However, it is considered that the fixed-quantity dispensing container constituting the conventional fixed-quantity dispensing container has various inconveniences. For example, the one described in Patent Document 1 is considered to be unsuitable for applications such as applying a liquid agent such as a hair restorer to the scalp because the internal pressure in the cylinder is increased and discharged from the discharge port at the upper end. .. In that respect, although the one described in Patent Document 2 can derive only a predetermined amount of the liquid agent and is suitable for the above-mentioned application to the scalp, the structure tends to be slightly complicated. be.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a quantitative injection container capable of eliminating the above-mentioned inconveniences. That is, it is an object of the present invention to provide a fixed-quantity dispensing container that is suitable for the application of a liquid agent to the scalp and is capable of accurate weighing and easy and reliable derivation of the measured liquid.

The quantitative injection container of the present invention has a container body having a storage space for containing a liquid inside, and a movable member that is mounted so as to be able to move up and down between a lowered state and an raised state with respect to the container body. I have. The movable member may be provided with a pipe portion that hangs downward inside the container body and has a liquid outlet space inside. A measuring chamber having an upper end opening that opens upward may be provided at the bottom of the container body. The bottom of the measuring chamber may be provided with a protrusion protruding upward. When the lower end of the pipe portion is in the descending state, the lower end portion is fitted into the protrusion portion to block the lead-out space from the storage space and the measuring chamber, while the lower end portion of the upper end opening of the measuring chamber is used from the opening edge portion. The measuring chamber can be configured to communicate with the storage space at a distance. Further, when the lower end portion of the pipe portion is in the raised state, the lower end portion thereof is separated from the protrusion portion to communicate the lead-out space with the measuring chamber, and is internally fitted into the opening edge portion of the upper end opening of the measuring chamber. The measuring chamber may be configured to be shielded from the storage space.

In the case of the present invention, when the movable member is in the lowered state, the inner peripheral edge portion of the switching portion fits outside the protrusion of the measuring chamber, so that the lower end opening of the switching portion is closed. Since the outer peripheral edge portion is separated from the opening edge portion of the upper end opening of the measuring chamber, the storage space in the pipe portion and the measuring chamber are communicated with each other through the upper end opening. Therefore, in the descending state, the liquid stored in the storage space is filled in the measuring chamber, while the lead-out space is cut off from the storage space and maintained in an empty state. When the movable member is raised from this lowered state to the raised state, the inner peripheral edge portion of the switching portion is disengaged from the protrusion and the lower end opening of the pipe portion is opened, while the outer peripheral edge portion of the switching portion is weighed. The measuring chamber is cut off from the storage space because it is in close contact with the opening edge of the upper end opening of the chamber. Therefore, the measuring chamber is in a state of communicating only with the lead-out space through the lower end opening of the switching portion. As a result, the liquid filled in the measuring chamber can be separated from the storage space, and this separation makes it possible to accurately measure a predetermined amount of liquid. At the same time as the weighing, the measured liquid can be led out only to the out-licensing space and poured out through the out-licensing space.

In the quantitative injection container of the present invention, the lower end of the pipe portion is fitted inside the opening edge of the upper end opening of the measuring chamber before being separated from the protrusion in the process from the descending state to the ascending state. It may be configured to do so. According to such a configuration, the liquid outlet space in the pipe portion does not communicate with the liquid storage space of the container body, and it is possible to accurately measure the liquid by the measuring chamber and dispense the liquid.

Further, a mouth portion is provided on the upper portion of the container body, the movable member is attached to the mouth portion so as to be able to move up and down in the central axis direction of the mouth portion, and the pipe portion is attached to the central axis. It hangs downward in the direction, the upper end opening of the measuring chamber is opened upward in the central axis direction, and the lower end of the pipe portion constitutes a switching portion for switching the state of the measuring chamber. The protrusion protrudes upward from the bottom of the measuring chamber in the central axis direction, and the switching portion constitutes a lower end opening that opens downward in the central axis direction and can be fitted externally to the protrusion, and the lower end opening. The configuration may include an inner peripheral edge portion that is slidable while being in close contact with the outer peripheral surface of the protrusion, and an outer peripheral edge portion that is slidable while being in close contact with the opening edge portion of the upper end opening. According to this, each part can be designed based on the central axis of the mouth part, and the structure can be easily assembled.

Preferably, the quantitative injection container of the present invention has a container body for accommodating a liquid, an independent internal space, and a pipe portion that communicates with the internal space and extends in the vertical direction and hangs downward in the central axial direction. A movable member that is attached to the mouth of the container body so as to be able to move up and down between the lowered state and the raised state in the central axis direction is provided, and the inside of the container body is formed by the pipe portion. It should be divided into a lead-out space inside the pipe section and a storage space excluding the inside of the pipe section. In this container, the container body is provided with a measuring chamber which is concavely divided at the bottom portion and the upper end opening opens upward in the central axial direction, while the pipe portion is provided with a measuring chamber at the lower end thereof. A switching unit for switching the above is provided. In addition, the measuring chamber is provided with a protrusion that rises upward in the central axis direction from the bottom of the measuring chamber, and the switching portion is a lower end opening that opens downward in the central axis X direction and can be fitted externally to the protrusion. An inner peripheral edge portion that constitutes the lower end opening and is slidable in close contact with the outer peripheral surface of the protrusion, and an outer peripheral edge portion that is slidable in close contact with the opening edge portion of the upper end opening. do. Then, when the movable member is in the lowered state of the measuring chamber and the switching portion, the inner peripheral edge portion of the switching portion is fitted onto the protrusion portion, and the outer peripheral edge portion of the switching portion is the opening of the upper end opening. By separating from the edge portion, the lower end opening of the switching portion is closed and the measuring chamber is communicated with the storage space through the upper end opening, while the switching is performed when the movable member is in the raised state. The inner peripheral edge portion of the portion is disengaged from the protrusion and the outer peripheral edge portion of the switching portion is brought into close contact with the opening edge portion of the upper end opening, so that the measuring chamber is passed through the lower end opening of the switching portion and the lead-out space is provided. It can be configured to be in a state of being communicated with the chisel.

The movable member of the quantitative injection container of the present invention can be engaged with the mouth of the container body so as to move up and down in the direction of the central axis by rotating spirally around the central axis. More specifically, for example, the movable member can be composed of an elevating operation member and a nozzle member. The elevating member is engaged with the container body so as to elevate and elevate in the direction of the central axis by spirally rotating around the central axis, and the nozzle member has a nozzle hole that can be opened and closed at the tip and elevates. It can be integrally connected to the operating member. Alternatively, the movable member can be composed of a nozzle member and a pipe member. That is, as a nozzle member, it has a nozzle hole that can be opened and closed at the tip, and is engaged with the container body so as to move up and down in the central axis direction by spirally rotating around the central axis, and as a pipe member. It is configured by being connected to the nozzle member so as to form the pipe portion.

In the case of a configuration that raises and lowers by rotation, a cap that is engaged so as to move up and down in the direction of the central axis by rotating spirally around the central axis is provided with respect to the container body, and the rotational force is applied as this cap. It can be configured to be communicably engaged with the movable member. As a result, it is possible not only to open and close the cap but also to convert the movable member into a descending state and an ascending state by simply performing a rotation operation for opening and closing the cap. The weighed liquid can be converted into a derivable state and ready for immediate use.

Further, the switching portion of the present invention can be configured by a large-diameter tubular portion having a predetermined range in the central axial direction including the lower end opening of the pipe portion having a larger diameter than other portions. As a result, the inner peripheral surface thereof may form the inner peripheral edge portion, and the outer peripheral surface may form the outer peripheral edge portion. Alternatively, the switching portion of the present invention can be configured by a donut annular plate-shaped portion protruding from the lower end opening of the pipe portion toward the inner and outer peripheral sides.

Further, a cap having a double lid structure engaged with the container body so as to move up and down in the central axis direction by spirally rotating around the central axis can be provided. In this case, as a movable member, a nozzle hole communicating with the internal space is provided, and the shaft portion of the valve body can be moved forward and backward from the internal space side in a state of being urged in the closing direction in the nozzle hole. An inner cap that is fitted and rotatably engaged with the container body as a cap, an outer cap that is displaceably covered with respect to the inner cap in the central axial direction, and a top wall portion of the outer cap. A convex rod portion that protrudes in the central axis direction so as to penetrate the top wall portion of the inner cap and a top wall portion of the outer cap are positioned at positions separated by a predetermined distance in the central axis direction with respect to the top wall portion of the inner cap. It can be composed of means of force. The inner cap and the outer cap are provided with engaging protrusions that project in opposite directions and engage with each other so that the rotational operation force from the outer cap can be transmitted to the inner cap, and the inner cap is attached. By being pushed down in the direction of the central axis against the force means, the engaging convex parts on both sides are engaged with each other so that the inner cap and the outer cap can rotate integrally, and the convex rod part pushes down the shaft part. The configuration may be such that the closing of the nozzle hole by the valve body is released so that the nozzle hole can be converted into a state in which the nozzle hole is communicated with the outside.

When a cap having such a double lid structure is provided, even if an internal pressure fluctuation occurs in the measuring chamber, for example, during a weighing operation (conversion from a descending state to an ascending state of the switching portion) by opening the cap. The internal pressure fluctuation can be released through the nozzle hole. As a result, even when the measured liquid is poured out, it can be poured out to the scalp or the like by a natural pouring flow. Moreover, by using the cap having a double lid structure, the release of the internal pressure fluctuation can be automatically performed by the cap opening operation without performing a special operation or the like.

As described above, according to the quantitative injection container of the present invention, accurate measurement and easy and reliable derivation of the measured liquid can be achieved. That is, when the movable member is in the lowered state, the measuring chamber can be in a state of communicating with the storage space in the pipe portion through the upper end opening thereof, and the liquid stored in the storage space is filled in the measuring chamber. On the other hand, the derived space can be isolated from the storage space and maintained in an empty state. When the movable member is raised from this lowered state to the raised state, the measuring chamber can be switched to a state in which the measuring chamber communicates only with the lead-out space through the lower end opening of the switching portion, and the liquid filled in the measuring chamber can be transferred from the storage space. It becomes possible to separate and accurately measure a predetermined amount of liquid. Then, at the same time as this weighing, the measured liquid can be led out only to the out-licensing space and can be poured out through the out-licensing space. Further, when the cap having a double lid structure is provided, even if the internal pressure fluctuation occurs in the measuring chamber during the measuring operation or the like, the internal pressure fluctuation can be released, and even when the measured liquid is poured out. In addition to being able to be injected into the scalp, etc. by a natural injection flow, such internal pressure fluctuations can be released automatically by opening the cap without performing any special operation. become.

<First Embodiment>
FIG. 1 shows a quantitative injection container according to the first embodiment of the present invention. When not in use, this fixed-quantity injection container is stored with a liquid (for example, a liquid such as a hair restorer) filled inside, and when in use, only a certain amount of liquid measured from the internal liquid is injected (applied). It is something that can be done. Then, in this fixed quantity pouring container, weighing is completed only by removing the cap in the upright state, and pouring is possible if the container is turned upside down as it is. There is no limit to the liquid that can be filled inside, and even if it is a highly volatile liquid such as a hair restorer, it will not cause any inconvenience and maintain a reliable storage state without the risk of liquid leakage. Accurate weighing and easy and reliable pouring can be achieved. In the following description, the state shown in FIG. 1 is referred to as an upright state, and the state in which the top and bottom are reversed is referred to as an inverted state. The axis X is the central axis of the fixed quantity pouring container and extends in the vertical direction. Of the "up and down" movements in the axis X direction, "ascending" means moving upward in FIG. 1 along the axis X, and "descending" means moving downward.

The fixed quantity pouring container is configured to include the following components. That is, the fixed-quantity pouring container includes a container main body 2 for filling a liquid, and an elevating and lowering actuating member 3 joined to the mouth portion 21 of the container main body 2 so as to be spirally slidable and rotatable around an axis X. The purpose is to open and close the nozzle member 4 which is covered with the elevating member 3 from above and engaged with the elevating member 3 so as to move integrally with the elevating member 3 and the nozzle hole 40 of the nozzle member 4. A spring valve 5 that keeps the nozzle hole 40 closed by an upward urging force, a pipe member 6 that is supported in a state in which the upper end is connected to the elevating operating member 3 and hangs downward, and the pipe member 6. A measuring chamber 7 that can be switched to various states such as opening, weighing, and derivation after weighing by the switching unit 62, a bottom lid 8 for detachably closing the bottom opening 22 of the container body 2, a nozzle member 4, and a rotation operation. It is configured to include a cap 9 that is screwed onto the upper portion of the container body 2 in a state of being engaged so as to transmit a force. The elevating operation member 3 can be formed integrally with the pipe member 6, and constitutes a movable member together with the nozzle member 4. Then, the pipe member 6 constitutes a pipe portion of the movable member.

As will be clear from the detailed description below, the fixed-quantity pouring container is connected to the nozzle member 4, the elevating operating member 3 and the elevating operating member 3 by opening the cap 9 in the closed cap state (rotating in the opening direction). The pipe member 6 is raised, which makes it possible to measure the measuring chamber 7 by switching from the open state to the closed state and to lead the measured liquid to the lead-out space 24 which is the space inside the pipe member 6. It has become. The same function can be achieved by directly rotating the nozzle member 4, and the cap 9 is not an essential component. However, in addition to the aesthetic advantage of the entire container, the measurement by the pipe member 6 is completed and the injection is performed immediately by the operation that is natural for the user to open and operate the cap 9 for the use of the fixed quantity injection container. The existence of the cap 9 is significant in that it is possible. All of the above components can be formed by synthetic resin molding. Hereinafter, each component will be described in detail.

The container body 2 is formed in a cylindrical shape extending along the axis X, for example, the mouth portion 21 on the upper end side has a smaller diameter than the others, and the lower end side is opened to form a bottom opening 22. The bottom opening 22 is provided to fill the inside with a liquid by opening the bottom lid 8. The inside of the container body 2 is divided into a storage space 23 which is a donut annular space on the outer peripheral side of the pipe member 6 and a lead-out space 24 which is a space inside the pipe member 6. The storage space 23 is a space for storing the liquid, and the lead-out space 24 is a space for leading the measured liquid to the nozzle hole 40.

Further, one or a plurality (two in the example) spiral guide grooves 211 and 211 (see also FIG. 2) are formed on the outer peripheral surface of the mouth portion 21. The convex portions 30 and 30 of the elevating and lowering actuating members 3 are individually slidably fitted in the guide grooves 211 and 211, and when the elevating and lowering actuating member 3 is rotated around the axis X, the convex portions 30 are formed. The elevating operation member 3 is elevated by being moved and guided along the spiral guide groove 211. The top end of the guide groove 211 is bent upward and opened to the end surface of the mouth portion 21, and by fitting the convex portion 30 from above through this opening, the elevating operating member 3 can be assembled to the container body 2. It has become.

In addition, one or a plurality (two in the example) spiral guide grooves 212 and 212 are also formed on the outer peripheral surface of the container body 2 on the lower side of the mouth portion 21. The convex portions 921 and 921 of the cap 9, which will be described later, are individually slidably fitted in the guide grooves 212 and 212, and when the cap 9 in the closed cap state is rotated around the axis X in the open direction, the cap 9 is convex. The portion 921 is spirally moved upward along the guide groove 212, and the cap 9 is raised. The top end of each guide groove 212 is also bent upward and opened upward, and the convex portion 921 protrudes upward from this opening 213 so that the cap 9 can be removed from the container body 2 and separated. ing. Further, by performing the reverse operation (inserting the convex portion 921 from the opening and rotating the cap 9 in the closing direction), the cap 9 can be returned to the closed cap state again.

The elevating operation member 3 includes a substrate portion 31 extending in a plane orthogonal to the axis X, a central hole portion 32 erected upward so that the axis X passes at the center position of the substrate portion 31, and the central hole portion 32. The upper midfoot portion 33, which is erected slightly on the inner peripheral side of the outer peripheral edge of the substrate portion 31 so as to surround the substrate portion 31 concentrically, and the outer cylinder portion 34 extending downward from the outer peripheral edge position of the substrate portion 31 are similarly centered. An inner tubular portion 35 extending downward from the position and a tubular lower midfoot portion 36 disposed between the two are integrally formed.

On the lower end edge of the outer cylinder portion 34, convex portions 30 and 30 projecting to the inner peripheral side and fitting into the guide groove 211 are formed at positions separated by, for example, 180 degrees in the circumferential direction, and the vertical concave groove 341 is formed at the same position. , 341 are formed. Vertical ribs 431 of the nozzle member 4, which will be described later, are fitted into the vertical recessed grooves 341 from above, and the rotational force from the nozzle member 4 can be transmitted to the elevating operation member 3.

The lower end portion of the inner cylinder portion 35 extends downward from the outer cylinder portion 34 and is externally fitted to the upper end portion 61 of the pipe member 6. For this outer fitting, a strong engaging means such as uneven engagement is used, whereby the elevating operating member 3 and the pipe member 6 are firmly connected to each other and sealed so as not to be relatively movable in the axial X direction. ing.

Further, the upper middle foot portion 33 is in close contact with the inner peripheral surface of the base end portion of the nozzle portion 41 described later of the nozzle member 4 so as to partition the inside of the nozzle portion 41. On the other hand, the lower middle foot portion 36 is pushed into the inner peripheral surface of the mouth portion 21 of the container body 2 from above to bring the elevating and lowering actuating member 3 into close contact with each other so as to be able to slide and rotate spirally around the axis X. The elevating operating member 3 is supported so as to be able to elevate and elevate to the container body 2 while sealing between the two. In addition, the elevating operation member 3 and the pipe member 6 can be integrally formed.

The nozzle member 4 includes a substantially hemispherical nozzle portion 41 having a nozzle hole 40 formed at the apex. A stepped surface 42 extending to the outer peripheral side is formed at the base of the nozzle portion 41, and the cover portion 43 extends downward from the outer peripheral position of the stepped surface 42. Vertical ribs 431 and 431 are formed at each position 180 degrees apart in the circumferential direction on the inner peripheral surface of the cover portion 43, while vertical concave grooves 432 and 432 are formed at the same positions on the outer peripheral surface. A locking projection 433 is formed on the lower end edge of the cover portion 43 so as to project toward the inner peripheral side. Then, the nozzle member 4 inserts the vertical rib 431 into the vertical concave groove 341 of the elevating and lowering operation member 3 from above, and locks the locking projection 433 to the lower edge on the outer peripheral side of the convex portions 30 and 30. Then, at the same time, the stepped surface 42 comes into contact with the outer peripheral edge portion of the substrate portion 31. As a result, the nozzle member 4 is integrally assembled with the elevating operation member 3, and is spirally twisted and rotated together with the elevating operation member 3 to move up and down.

Further, a spring valve 5 is arranged between the elevating operation member 3 and the nozzle member 4. That is, the annular pedestal 51 on the base end side of the spring valve 5 (see also FIG. 3) cannot move relative to the central hole 32 of the elevating operating member 3 in the axis X direction due to, for example, undercut fitting. The inside of the nozzle member 4 and the inside of the pipe member 6 are communicated with each other through the central hole portion 32. Then, the valve body 54 (see also FIG. 4A) having the convex shaft portion 52 on the tip end side of the spring valve 5 receives the elastic urging force from the elastic arm portion 53 with respect to the nozzle hole 40. It is fitted inward from the bottom to the top so that a part of the tip protrudes from the nozzle hole 40. In this state, the valve body 54 extending from the lower position of the shaft portion 52 to the periphery is pressed upward against the seat surface formed by the inner peripheral surface below the nozzle hole 40 and is brought into close contact with the nozzle hole. The 40 is kept in a closed state.

Reference numeral 521 in FIG. 4A is a concave groove, and at least one (three in the example) is formed around the shaft portion 52. Then, when the shaft portion 52 protruding from the nozzle hole 40 is pushed, the valve body 54 is separated from the seat surface in the nozzle portion 41 (see FIG. 4B), and the nozzle hole 40 is in an open state, whereby the nozzle member The lead-out space 24 (see FIG. 1) composed of the spaces inside the 4 and the pipe member 6 and the outside communicate with each other through the concave groove 521.

The upper end portion 61 of the pipe member 6 is connected to the elevating operating member 3 and is supported in a suspended state. Further, the pipe member 6 is provided with a switching portion 62 at the lower end portion thereof. The switching unit 62 either opens the measuring chamber 7 facing the storage space 23 or shuts the measuring chamber 7 from the storage space 23, depending on whether the pipe portion 6 is in the lowered state or the rising state. It is configured to switch to a state of communicating with the lead-out space 24 so that the measured predetermined amount of liquid can be led out to the lead-out space 24. For this purpose, the switching portion 62 is formed as a large-diameter tubular portion in which the lower end portion of the pipe member 6 is increased in diameter by a predetermined amount over a predetermined range in the axis X direction, and the inner peripheral surface (inner peripheral edge portion) thereof is formed. ) Is formed so that it can be closely fitted from above to the hat-shaped protrusion 71 described later in the measuring chamber 7, while the shape of the outer peripheral surface (which constitutes the outer peripheral edge) of the measuring chamber 7 is formed. It is formed so as to be able to come into close contact with the opening edge 72 described later. As a result, the switching portion 62 descends and fits the protrusion 71 from top to bottom in the axis X direction, so that the lead-out space 24 in the pipe portion 6 is cut off from the measuring chamber 7 and the storage space 23. , The storage space 23 reaches a descending state in which it is communicated with the measuring chamber 7 through the gap 73 (the state shown in FIGS. 1 and 5A). On the contrary, when the switching portion 62 rises and comes off from the protrusion 71 and the outer peripheral surface of the switching portion 62 comes into close contact with the opening edge 72, the gap 73 is closed and the measuring chamber 7 has the storage space 23 and the lead-out space. When any of the 24 is cut off (see FIG. 5B) and the switching portion 62 rises further upward while the lower end outer peripheral surface of the switching portion 62 is in close contact with the opening edge 72, the inside of the measuring chamber 7 is switched. An ascending state is reached in which the lead-out space 24 is communicated with the lead-out space 24 through the lower end opening of the portion 62 (the state shown in FIG. 5C).

The measuring chamber 7 is partitioned so that the upper end opens upward and the inside has a predetermined volume. The measuring chamber 7 is provided with a protrusion 71 that projects upward in a hat shape from the center position through which the axis X at the bottom of the container body 2 passes, and an opening edge 72 formed in a predetermined opening shape at the upper end opening. There is. The measuring chamber 7 is formed by a first lid member 81 constituting the bottom lid 8 and a second lid member 82. The first lid member 81 is composed of a donut annular top plate portion in which an opening forming the opening edge 72 is formed at a central position, and a tubular wall portion extending downward from the top plate portion. By press-fitting the peripheral edge of the plate portion from the bottom opening 22 of the container body 2 into the inner peripheral surface of the bottom portion, the peripheral portion is detachably fixed at a predetermined position. The second lid member 82 includes an outer lid wall and an engaging portion that protrudes from the outer lid wall toward the first lid member 81 and is engaged by being fitted externally to the tubular wall portion. It is composed of. Then, on the outer lid wall of the second lid member 82, a protrusion forming the protrusion 71 is formed from the center position toward the inside of the container body 2. By assembling the first lid member 81 and the second lid member 82 to the container body 2 so as to close the bottom opening 22, the bottom lid 8 is formed and the measuring chamber 7 is formed. It is composed.

The cap 9 includes a top wall portion 91 and a tubular wall portion 92 extending downward from the outer peripheral edge position of the top wall portion 91. The top wall portion 911 is formed with an annular protective cylinder 911 that projects downward from the inner surface at the center position thereof. The protective cylinder 911 protrudes more than the amount of protrusion of the shaft portion 52 protruding from the nozzle hole 40, and surrounds the shaft portion 52 inside so that the lower end can come into contact with the top of the nozzle portion 41. As a result, it is possible to prevent an unintended external force from acting on the shaft portion 52 and to reliably maintain the closed state of the nozzle hole 40 by the shaft portion 52. Further, the tubular wall portion 92 is formed with convex portions 921, 921 protruding toward the inner peripheral side by one or two or more (two at positions 180 degrees apart in the circumferential direction in the figure) from the lower end edge thereof. At the same time, vertical ribs 922 and 922 are formed so as to project toward the inner peripheral side from the same position in the upper range of the tubular wall portion 92.

To put the cap 9 in the closed cap state, the cap 9 is put on the nozzle member 4 and engaged with the container body 2 and the nozzle member 4. That is, the convex portion 921 of the cap 9 is fitted into the top end of the guide groove 212 through the opening 213 (see FIG. 2) of the container body 2, and the vertical rib 922 is inserted into the vertical concave groove 432 of the nozzle member 4 from above, and then In addition, the cap 9 can be closed by twisting and rotating the cap 9 to the end of the guide groove 212. At the same time, by closing the cap 9, the nozzle member 4, the elevating operating member 3 and the pipe member 6 can be brought into the lowered state (the state shown in FIG. 1).

That is, the guide groove 211 for the nozzle member 4 and the guide groove 212 for the cap 9 have the same swivel guide amount (stroke) for both the nozzle member 4 and the cap 9 from the top end position to the end position, respectively. Is set to. As a result, by rotating the cap 9 in the closed cap state from the terminal position of the guide groove 212 to the top end position, the nozzle member 4 and the elevating operation member 3 are also rotationally operated from the terminal position to the top end position of the guide groove 211. , The pipe member 6 is designed to rise from the lowered state to the raised state.

The above-mentioned fixed-quantity pouring container is assembled as follows and filled with a liquid. For example, an elevating operating member 3 to which a pipe member 6 is connected and a nozzle member 4 are assembled with a spring valve 5 interposed therebetween, and a cap 9 further attached to the nozzle member 4 is attached to the container body 2. Assemble and close the cap. Next, in a state where the top and bottom are reversed, a predetermined amount of liquid such as a chemical solution is filled into the storage space 23 from the bottom opening 22 at the bottom of the container body 2, and then the bottom lid 8 is fitted to fit the bottom lid 8 of the container body 2. Once the bottom is closed, the metered dose container can be used.

Subsequently, the method of using this fixed-quantity dispensing container will be described with reference to FIG. 6. When the cap 9 is in the closed cap state (see the left end portion of FIG. 6), the elevating operation member 3 and the pipe member 6 are lowered. In the state, the switching portion 62 is in close contact with the outer peripheral surface of the protrusion 71 of the measuring chamber 7 and the outer peripheral corner portion of the top wall, whereby the lower end opening of the switching portion 62 is sealed and the lead-out space 24 is the storage space 23. The measuring chamber 7 communicates with the storage space 23 through the gap 73 (see FIG. 5A) between the opening edge 72 and the pipe member 6, and the inside of the measuring chamber 7 is filled with liquid. There is.

From this closed cap state, first, the cap 9 is twisted and rotated around the axis X to open the cap. Then, the convex portion 921 slides along the guide groove 212, so that the cap 9 rises while rotating (see the central portion of FIG. 6). This rotational force is transmitted to the nozzle member 4 by the vertical rib 922 fitted in the vertical concave groove 432, and the nozzle member 4 rotates in synchronization with the cap 9. At the same time, as the nozzle member 4 rotates, the rotational force is transmitted to the elevating operating member 3 by the vertical rib 431 fitted in the vertical recessed groove 341, and the elevating operating member 3 also rotates in synchronization with the cap 9. Become. Due to the rotational operation of the elevating and lowering operating member 3, the convex portion 30 slides along the guide groove 211, whereby the elevating and lowering operating member 3 also rises while rotating. Further, as the elevating operating member 3 rises, the pipe member 6 including the switching portion 62 that has been in the lowered state also rises at the same time, the switching portion 62 separates from the protrusion 71, and its outer peripheral surface is in close contact with the opening edge 72. (See FIG. 5 (b)). As a result, the measuring chamber 7 is closed, and the amount of liquid corresponding to the internal volume of the measuring chamber 7 is separated from the liquid in the storage space 23, that is, the liquid is weighed.

Further, when the outer peripheral surface of the switching portion 62 slides in close contact with the opening edge 72 as the cap 9 is rotated and the convex portion 921 reaches the top end position of the guide groove 212, the nozzle member 4, the elevating operating member 3 and the elevating operating member 3 The pipe member 6 reaches the ascending state (see the right end portion of FIG. 6). In this raised state, the outer peripheral surface of the lower end portion of the switching portion 62 is in close contact with the opening edge 72, while the inner peripheral surface of the switching portion 62 and the protrusion 71 are completely released from each other and a gap is formed between them. It will be vacant (see FIG. 5 (c)). As a result, the inside of the measuring chamber 7 communicates with the leading-out space 24, and the liquid in the measuring chamber 7 can be led out to the leading-out space 24.

Then, by pulling the cap 9 that has reached the raised state upward, the convex portion 921 is pulled upward from the opening 213 at the top end of the guide groove 212 (see the left side portion of FIG. 7), and the cap 9 is pulled out from the container body 2. Can be separated. Next, the container body 2 is turned upside down to be in an inverted state (see the right part of FIG. 7). As a result, the liquid measured in the measuring chamber 7 is led out to the lead-out space 24, and falls into the nozzle member 4 through the inner cylinder portion 35 and the central hole portion 32. When the shaft portion 52 is pressed against the affected portion (for example, the scalp) H in this inverted state, the elastic arm portions 53, ... Of the spring valve 5 bend and the shaft portion 52 retracts (see also FIG. 4 (b)). Since the nozzle hole 40 is opened through the concave groove 521, the liquid can be poured out to the scalp H and applied.

After use, the fixed quantity pouring container is returned to the upright state, the vertical rib 922 of the cap 9 is fitted into the vertical concave groove 432 of the nozzle member 4, and the convex portion 921 is fitted from the opening 213 of the guide groove 212 of the container body 2 to the top end. By pushing and turning the cap 9 in the container, the cap 9 is twisted and rotated in the direction opposite to the opening operation to return to the original closed cap state. As a result, the nozzle member 4, the elevating actuating member 3, and the pipe member 6 also rotate synchronously and return to the descending state.

According to the above-mentioned quantitative injection container, when it is desired to inject a predetermined amount of liquid from the container body 2 in which the liquid is stored, an accurate amount of the predetermined amount of liquid can be accurately obtained by simply rotating the cap 9 in the closed cap state in the opening direction. It will be possible to perform weighing and reliable removal (deriving and pouring) of the measured liquid. In other words, by simply opening the cap 9 which is absolutely necessary for a container with a cap, weighing and pouring can be performed accurately and reliably, eliminating the need for other special operations. can do. Moreover, if the cap 9 is in the open cap state, it has already been converted into a measurable state by the open cap operation, and the user is in a state where a certain amount of liquid can be poured out and applied. You can grasp it immediately at a glance.

Further, a combination of the convex portion 921 and the spiral guide groove 212 is adopted as the elevating operation mechanism of the cap 9, or a combination of the convex portion 30 and the spiral guide groove 211 is adopted as the elevating operation mechanism of the elevating operation member 3. Therefore, as compared with the case of adopting a normal screw coupling (for example, screwing with a screw screw), the amount of lifting and lowering for the same rotation operation can be significantly increased, and a reliable operation can be obtained by a simple operation.

In addition, when not in use, that is, in the closed cap state in which the cap 9 is put on the container body 2, the pipe member 6 is in the lowered state, so that the lead-out space 24 can be cut off from the storage space 23. Further, in both the process of the pipe member 6 reaching the raised state and the raised state in which the cap 9 is removed, the outer peripheral surface of the pipe member 6 is brought into close contact with the opening edge 72 of the measuring chamber 7 to provide the lead-out space 24. It can be cut off from the storage space 23. As described above, the liquid contained and stored in the container body 2 is sealed regardless of whether it is in the lowered or raised state, or even if the fixed-quantity dispensing container is placed in a state such as lying down instead of in an upright state. The state can be maintained, and the occurrence of liquid leakage or the like can be avoided.

The other configurations are the same as those of the quantitative injection container of the first embodiment, unlike the quantitative injection container of. Hereinafter, only the different points will be described, and the same reference numerals as those of the first embodiment will be added to the other similar configurations, and duplicate description will be omitted.

The container body 2a is formed with a tubular support portion 25 that is in close contact with the outer peripheral surface of the inner cylinder portion 35 at a position protruding downward from the inner peripheral surface at a lower position away from the mouth portion 21 to the inner peripheral side. ing. On the outer peripheral surface of the inner cylinder portion 35, a bulging portion 351 slightly bulging toward the outer peripheral side is formed on the entire circumference, and the bulging portion 351 is in close contact with the inner peripheral surface of the support portion 25, whereby the inner cylinder portion 35 is in close contact with the inner peripheral surface. The portion 35 is securely sealed so that it can slide in a spiral shape.

Specifically, when the elevating operating member 3 and the pipe member 6 are in the lowered state, the bulging portion 351 is located near the lower end opening of the supporting portion 25, and a minute gap is formed between the bulging portion 351 and the inner peripheral surface of the supporting portion 25. It will be in a state of existence. That is, the storage space 23 and the internal space of the nozzle member 4 are in a state of communicating with each other through this gap and the through hole 311. On the other hand, when the elevating operation member 3 and the pipe member 6 move up and down from the descending state to the ascending state, the bulging portion 351 slides in close contact with the inner peripheral surface of the supporting portion 25 to completely fill the storage space 23. It is designed to be sealed.

By providing the support portion 25, the donut-shaped space between the inner cylinder portion 35 and the mouth portion 21 is divided into upper and lower parts by the substrate portion 31 and the support portion 25, but the through hole 311 is provided. , 311 communicates with the internal space of the nozzle member 4.

<Second Embodiment>
FIG. 9 shows a quantitative injection container according to the second embodiment of the present invention. Although the shape of this quantitative injection container is different from that of the measuring chamber 7 and the switching unit 62 of the first embodiment in the configuration of the measuring chamber 16 and the switching unit 136, the container is in line with the first embodiment in its principle. Moreover, the elevating mechanism for elevating and lowering the pipe member 13 by the rotation operation is also in line with that of the first embodiment. On the other hand, as the configuration of the cap 18, a push-and-turn type double lid configuration is adopted, and the occurrence of internal pressure fluctuation is eliminated by using this, which is significantly different from the first embodiment.

The quantitative injection container of the second embodiment has a container body 12 for filling a liquid and a pipe that is inserted inside from the mouth portion 121 of the container body 12 and moves up and down in the axis X (central axis extending in the vertical direction) direction. A nozzle that is integrally connected to the pipe member 13 by being covered with the upper part of the pipe member 13 from above and engaged with the member 13 and is engaged with the container body 12 so as to be able to move up and down by rotating around the axis X. A spring valve for opening and closing the nozzle hole 140 of the member 14 and the nozzle member 14 by applying an upward urging force between the nozzle hole 140 and the pipe member 13 to keep the nozzle hole 140 in a closed state. 15, a measuring chamber 16 that can be switched to various states such as opening, weighing, and derivation after weighing by the switching portion 136 of the pipe member 13, and a bottom lid 17 for detachably closing the bottom opening 122 of the container body 12. A cap 18 screwed onto the upper portion of the container body 12 in a state of being engaged with the nozzle member 14 so as to be able to transmit a rotational operation force in the circumferential direction. That is, in the first embodiment, the two members separated into the elevating operation member 3 and the pipe member 6 are integrated into the pipe member 13 in the second embodiment, and this is integrally connected to the nozzle member 14. The elements are simplified. The pipe member 13 and the nozzle member 14 form a movable member, and the pipe member 13 constitutes a pipe portion of the movable member.

The quantitative injection container of the second embodiment is also connected to the nozzle member 14 and the nozzle member 14 by opening the cap 18 in the closed cap state (rotating in the opening direction), as will be clear from the detailed description below. The pipe member 13 is raised, which makes it possible to measure the measuring chamber 16 by switching from the open state to the closed state and to lead the measured liquid to the lead-out space 124, which is the space inside the pipe member 13. It has become. In addition, in the quantitative injection container of the second embodiment, at the time of the switching, the spring valve 15 that closes the nozzle hole 140 is converted to the open state by the push operation of the cap 18, thereby weighing. The internal pressure fluctuation that may occur in the chamber 16 is allowed to escape to the outside. Hereinafter, each component will be described in detail.

The container body 12 is formed in a cylindrical shape extending along the axis X, for example, the mouth portion 121 on the upper end side is gradually reduced in diameter in two stages, and the lower end side is opened to form a bottom opening 122. The bottom opening 122 is provided to fill the inside with a liquid by opening the bottom lid 17. The inside of the container body 12 is divided into a storage space 123, which is a donut annular space on the outer peripheral side of the pipe member 13, and a lead-out space 124, which is a space inside the pipe member 13. The storage space 123 is a space for storing the liquid, and the lead-out space 124 is a space for leading the measured liquid to the nozzle hole 140.

The container body 12 is formed with an inner peripheral flange 125 that protrudes from the base end side position of the mouth portion 121 to the inner peripheral side. The inner peripheral edge of the inner peripheral flange 125 comes into contact with the pipe portion 135 of the pipe member 13, which will be described later, to guide and support the elevating operation of the pipe member 13.

Further, on the outer peripheral surface of the mouth portion 121, one or a plurality of spiral guide grooves 1211, 1211 (two in the illustrated example) are formed as in the first embodiment. The convex portions 144 and 144 of the nozzle member 14, which will be described later, are individually fitted into the guide grooves 121 and 1211 so as to be slidable, and when the nozzle member 14 is rotationally operated around the axis X, the convex portions 144 are formed. The nozzle member 14 and the pipe member 13 are moved up and down by being moved and guided along the spiral guide groove 1211. The top end of the guide groove 1211 is bent upward and opened to the end surface of the mouth portion 121, and by fitting the convex portion 144 from above through this opening, the nozzle member 14 can be assembled to the container body 12. ing.

In addition, one or a plurality (two in the example) spiral guide grooves 1212, 1212 are formed on the outer peripheral surface of the lower portion of the mouth portion 121 as in the first embodiment. The convex portions 180, 180 of the cap 18, which will be described later, are individually slidably fitted in the guide grooves 121 and 1212, and when the cap 18 in the closed cap state is rotated around the axis X in the open direction, the cap 18 is convex. The portion 180 is spirally moved upward along the guide groove 1212, and the cap 18 is raised. The top end of each guide groove 1212 is also bent upward and opened upward, and the convex portion 180 protrudes upward from this opening so that the cap 18 can be removed from the container body 12 and separated. There is. Further, by performing the reverse operation (inserting the convex portion 180 from the opening and rotating the cap 18 in the closing direction), the cap 18 can be returned to the closed cap state again.

The pipe member 13 is concentric with a substrate portion 131 extending in a plane orthogonal to the axis X, a central hole portion 132 erected upward so that the axis X passes at the center position of the substrate portion 131, and the central hole portion 132. The midfoot portion 134, which is erected slightly on the inner peripheral side while leaving the outer peripheral edge portion 133 of the substrate portion 131 so as to surround the substrate portion 131, and the lower part from the central position of the substrate portion 131 so as to be continuous with the hole of the central hole portion 132. A pipe portion 135 extending to the pipe portion 135 and a switching portion 136 provided at the lower end portion of the pipe portion 135 are provided and integrally formed.

The pedestal 151 of the spring valve 15 is fitted onto the central hole 132, and the midfoot 134 is pushed into the inner peripheral surface of the base end portion of the nozzle portion 141 described later of the nozzle member 14, and the outer peripheral edge of the substrate portion 131 is formed. The portion 133 is locked so as not to be relatively movable in the axis X direction at a position below the step portion 142 described later of the nozzle member 14. Specifically, in a state where the upper surface of the outer peripheral edge portion 133 is in contact with the lower surface of the step portion 142, the lower edge of the outer peripheral edge portion 133 engages with the engaging portion 1430 protruding from the inner surface of the nozzle member 14 to the inner peripheral side. By combining, the pipe member 13 and the nozzle member 14 are connected to each other so as not to be relatively movable.

The switching portion 136 (see also FIG. 11) is composed of a donut annular plate-shaped portion provided so as to close the lower end of the pipe portion 135. When the pipe member 13 is in the lowered state (the state shown in FIGS. 9 and 11A), the inner peripheral edge portion 1361 of the switching portion 136 can slide on the outer peripheral surface of the rod-shaped protrusion 161 described later in the measuring chamber 16. The lead-out space 124 is cut off from the storage space 123 by closing the lower end opening formed by the inner peripheral edge portion 1361. On the other hand, when the pipe member 13 is in the raised state (the state shown in FIG. 11B), the outer peripheral edge portion 1362 of the switching portion 136 is slidably brought into close contact with the opening edge portion 162 described later in the measuring chamber 16 and is opened. The upper end opening of the measuring chamber 16 formed by the edge portion 162 is closed to shut off the measuring chamber 16 from the storage space 123, while the measuring chamber 16 is communicated with the lead-out space 124 through the opening formed by the inner peripheral edge portion 1361. Will be. A pedestal 163 extending in a direction orthogonal to the axis X is formed at the base of the rod-shaped protrusion 161 so that the lower surface continuous from the inner peripheral edge portion 1361 of the descending switching portion 136 abuts on the upper surface of the pedestal 163. It has become. As a result, the blocking function of the switching unit 136 in the descending state can be maintained more firmly.

The nozzle member 14 includes a substantially hemispherical nozzle portion 141 having a nozzle hole 140 formed at the apex, a step portion 142 extending outward from the base portion of the nozzle portion 141, and a cover extending downward from the outer peripheral position of the step portion 142. It is configured to include a portion 143. Vertical concave grooves 1431 and 1431 are formed on the outer peripheral surface of the cover portion 143 at positions separated by 180 degrees in the circumferential direction, and convex portions 144 and 144 are formed at the same positions on the lower end edge of the cover portion 143. It is formed so as to protrude toward the circumferential side. A vertical rib 184, which will be described later, of the cap 18 is internally fitted in each of the vertical recessed grooves 1431 so that the rotational operation force of the cap 18 can be transmitted to the nozzle member 14.

The spring valve 15 has the same configuration as the spring valve 5 (see FIG. 3) of the first embodiment, and has a tubular pedestal 151 that is externally fitted into the central hole 132 of the pipe member 13 from above, and a nozzle member 14. It is provided with a valve body 154 for closing the nozzle hole 140 and an elastic arm portion 153 for exerting an elastic urging force between the pedestal 151 and the valve body 154. The valve body 154 has a shaft portion 152 that is inserted into the nozzle hole 140 from below, and the shaft portion 152 (see also FIG. 10A) receives an elastic urging force from the elastic arm portion 153. , It is fitted inward with respect to the nozzle hole 140 from the bottom to the top so that a part of the tip thereof protrudes from the nozzle hole 140. In this state, the valve body 154 extending from the lower position of the shaft portion 152 to the periphery is pressed upward against the seat surface formed by the inner peripheral surface below the nozzle hole 140 and is brought into close contact with the nozzle hole. The 140 is designed to be kept closed.

Reference numeral 155 in FIG. 10 is a concave groove, and at least one (for example, three in the radial direction at intervals from each other) is formed around the shaft portion 152. Then, when the shaft portion 152 protruding from the nozzle hole 140 is pushed and the valve body 154 separates from the seating surface in the nozzle portion 141 (see FIG. 10B), each space in the nozzle portion 141 and the pipe member 13 is formed. The lead-out space 124 composed of the above is in a state of communicating with the outside through the concave groove 521, that is, the nozzle hole 140 is in an open state.

The measuring chamber 16 opens upward and is partitioned so that the inside has a predetermined volume. The measuring chamber 16 includes a protrusion 161 that projects upward in a rod shape from the center position through which the axis X at the bottom of the container body 2 passes, and an opening edge portion 162 formed in a predetermined opening shape. The measuring chamber 16 is formed by a first lid 17a and a second lid 17b constituting the bottom lid 17. The first lid member 17a has a recess that opens upward at the center position, and a tubular second lid member 17b is internally fitted and fixed to the recess from above. A pedestal 163 is formed at a position one step above the bottom surface of the recess of the first lid member 17a, and a rod-shaped protrusion 161 is formed so as to project from the pedestal 163. The protrusion 161 and the opening edge 162 are set to have a length in the axis X direction corresponding to the elevating stroke between the descending state and the ascending state of the switching portion 136. In addition, the upper end opening side of the second lid member 17b has a slightly smaller diameter to form the opening edge portion 162. The bottom lid 17 may not be separated into the first lid 17a and the second lid 17b, but both may be integrally formed.

As shown in FIG. 10, the cap 18 has a double lid structure in which an inner cap 18a and an outer cap 18b are combined, and is configured in a push-and-turn system provided with a CR mechanism (Child Rest mechanism). ..

That is, the outer cap 18b is urged upward with respect to the inner cap 18a by the urging means 193 described later, and the outer cap 18b is pushed downward against the urging force to push down the outer cap 18b and the inner cap 18a. Engage so that they rotate together. On the other hand, when the outer cap 18b at the upper position is rotated in the closing direction (tightening direction), the inner cap 18a is also rotated in the closing direction by engaging with the inner cap 18a, but is moved to the upper position. Even if a certain outer cap 18b is rotated in the opening direction (removal direction), the outer cap 18b is configured to rotate (idle) while sliding with respect to the inner cap 18a.

In short, even if the outer cap 18b in the closed cap state is rotated in the opening direction without pushing it down, the opening operation becomes impossible just by idling, so that the CR mechanism is secured and the outside is based on a clear opening operation intention. If the cap 18b is rotated in the opening direction while being pushed down, it can be rotated in the opening direction integrally with the inner cap 18a to enable the opening operation. At the same time, the nozzle hole 140 is converted to the open state and the inside of the measuring chamber 16 is operated. It will be possible to release the internal pressure that may fluctuate. Hereinafter, a specific description will be given.

The inner cap 18a includes a top wall portion 181 that covers the nozzle member 14, and a peripheral wall portion 182 that extends downward from the outer peripheral edge position of the top wall portion 181. Further, the outer cap 18b includes a top wall portion 191 that covers the top wall portion 181 and a peripheral wall portion 192 that extends downward from the outer peripheral edge position of the top wall portion 191 and can cover the peripheral wall portion 182 and be housed inside. It is composed of. Then, the outer cap 18b is put on the inner cap 18a from above, and is coupled to a predetermined relationship by engaging the locking portions 183 and 193 of the two. That is, in a state where a predetermined gap is opened between the two top wall portions 181, 191 by receiving the urging force by the urging means described later, the outer cap 18b is allowed to be displaced downward with respect to the inner cap 18a, but the inner cap 18a is relative to the inner cap 18a. Further upward displacement of the outer cap 18b is prevented. In addition, one or two or more vertical ribs 184 and 184 (two at positions 180 degrees apart in the circumferential direction) project to the inner peripheral side on the inner peripheral surface of the peripheral wall portion 182 of the inner cap 18a. The vertical rib 184 is formed, and the vertical rib 184 is internally fitted into the vertical recessed groove 1431 of the cover portion 143 of the nozzle member 14 from above.

The inner cap 18a (see also FIG. 12) has an engaging convex portion 185 projecting upward from a predetermined portion in the circumferential direction of the outer peripheral edge of the top wall portion 181 and a unidirectional engaging portion provided on the upper surface of the inner position thereof. A hole 187 for inserting a step portion 186 and a convex rod portion 195 described later through the center position of a top wall portion 181 through which the shaft X passes, and a protective cylinder 188 whose hole edge projects downward by a predetermined amount. And have. The engaging convex portions 185 and the unidirectional engaging step portions 186 are arranged at a plurality of locations (three locations in the illustrated example) at equal intervals in the circumferential direction. Each engaging protrusion 185 is provided with engaging surfaces that are substantially perpendicular to both ends in the circumferential direction. Further, each unidirectional engaging step portion 186 is provided with a hurdle portion provided so as to project from the upper surface of the top wall portion 181, and is composed of a substantially vertical surface formed on one side of the hurdle portion in the circumferential direction. There is.

By engaging the tip of the elastic engaging piece 193 of the outer cap 18b, which will be described later, with the one-way engaging step portion 186, the inner cap 18a is rotated together with the outer cap 18b in the closing direction (tightening direction). It has become possible. On the other hand, an inclined surface is formed on the other side in the circumferential direction of the hurdle portion, and if the outer cap 18b located at the upper position is rotated in the opening direction, the elastic engaging piece 193 is inclined in the one-way engaging step portion 186. Overcoming the hurdle portion along the surface, the upper surface of the inner cap 18a is slid. At that time, when passing through the one-way engaging step portion 186, the elastic engaging piece 193 is struck against the top wall portion 181 by its own elastic restoring force and makes a clicking sound.

The protective cylinder 188 projects downward more than the amount of protrusion of the shaft portion 152 protruding from the nozzle hole 140, and surrounds the shaft portion 152 inside so that the lower end of the protective cylinder 188 can come into contact with the top of the nozzle portion 141. It has become. As a result, when the cap 18 is in the closed cap state, it is possible to prevent an unintended external force from acting on the shaft portion 152, and to ensure that the nozzle hole 140 is maintained in the closed state by the shaft portion 152.

The outer cap 18b (see also FIG. 13) is provided in the vicinity of the outer peripheral edge of the lower surface of the top wall portion 191 and the three elastic engaging pieces 193, 193 ... It is provided with three engaging convex portions 194 and 194, and a convex rod portion 195 projecting downward along the axis X from the center position of the top wall portion 191. Each elastic engagement piece 193 constitutes an urging means.

The tip (lower end) of each elastic engagement piece 193 (see also FIG. 14) is in contact with the upper surface of the top wall portion 181 of the inner cap 18a, and the outer cap 18b is urged by the urging force of each elastic engagement piece 193. Is urged at an upper position (see FIG. 10A) separated above the inner cap 18a by a predetermined interval. When the outer cap 18b is positioned at this upper position, the engaging protrusions 185 and 194 are separated from each other in the vertical direction to be disengaged from each other, and the convex rod portion is formed in the hole 187. The lower end of the 195 and the upper end of the shaft portion 152 are arranged so as to be spaced apart from each other. Then, when the outer cap 18b is pushed downward against the urging force of each elastic engaging piece 193 (see FIG. 10B), the engaging convex portion of the outer cap 18b with respect to the engaging convex portion 185 of the inner cap 18a. The portion 194 is engaged in the circumferential direction so that the inner cap 18a can be integrally rotated by any rotation operation of the outer cap 18b in the opening direction or the closing direction, and the convex rod portion 195 is a shaft. By pushing down the portion 152 downward, the nozzle hole 140 is opened through the concave groove 155.

In addition to the elastic engaging piece 193, another urging means may be provided on the inner cap 18a side or the outer cap 18b side. Further, instead of the combination of the elastic engaging piece 193 and the unidirectional engaging step portion 186, a combination of the same functions shall be provided between the peripheral wall portions 182 and 192 of the inner cap 18a and the outer cap 18b. Can be done.

The method of using the quantitative injection container of the second embodiment will be described with reference to FIG. 15. First, when the cap 18 is in the closed cap state (see the left end portion of FIG. 15), the nozzle member 14 and the pipe member 13 are used. Is in the lowered state, and the switching portion 136 comes into close contact with the outer peripheral surface of the protrusion 161 (see FIG. 11A) of the measuring chamber 16 and the upper surface of the pedestal 163. As a result, the lower end opening formed by the inner peripheral edge portion 1361 of the switching portion 136 is sealed and the lead-out space 124 is blocked from the measuring chamber 16 and the storage space 123, while the measuring chamber 16 has the opening edge 162 and the pipe portion 135. The inside of the measuring chamber 16 communicates with the storage space 123 through the gap between the two and is filled with liquid.

From this closed cap state, first, the cap 18 is pushed and turned in the opening direction around the axis X to perform the opening cap operation. That is, with the outer cap 18b pushed down (see the central portion of FIG. 15), the rotation operation is performed. When the outer cap 18b is pushed down, the engaging convex portion 194 of the outer cap 18b (see also FIG. 10B) engages with the engaging convex portion 185 of the inner cap 18a in the circumferential direction to the outer cap 18b. The inner cap 18a also rotates integrally by the rotation operation of the above, and the convex portion 180 slides along the guide groove 1212, so that the cap 18 rises while rotating in a spiral shape and reaches an ascending state (FIG. FIG. See the right part of 15).

That is, the rotational force of the inner cap 18a is transmitted from the vertical rib 184 to the concave groove 1431 of the nozzle member 14 in the fitted state, and the nozzle member 14 also rotates in synchronization with the cap 18. As the nozzle member 14 rotates, the convex portion 144 slides along the guide groove 1211, so that the nozzle member 14 and the pipe member 13 connected to the nozzle member 14 also rise while spirally rotating. When the switching portion 136 that was in the lowered state starts to rise as the pipe member 13 rises, the outer peripheral edge portion 1362 thereof begins to come into close contact with the opening edge 162, and then the switching portion 136 separates from the protrusion portion 161. As a result, an ascending state (see FIG. 11B) is reached. As a result, the measuring chamber 16 is cut off from the storage space 123 and communicates only with the lead-out space 124, while the amount of liquid corresponding to the internal volume of the measuring chamber 16 is separated from the liquid in the storage space 123. In other words, it will be weighed.

Further, by pushing down the outer cap 18b, the convex rod portion 195 is lowered toward the shaft portion 152 and the shaft portion 152 is pushed down, whereby the nozzle hole 140 is opened and converted. Therefore, it becomes possible to release the internal pressure fluctuation that may occur in the process from the descending state to the ascending state of the switching unit 136. That is, when the switching portion 136 slightly rises from the lowered state shown in FIG. 11A, the inner peripheral edge portion 1361 of the switching portion 136 comes into close contact with the outer peripheral surface of the protrusion 161, and at the same time, the outer peripheral edge portion 1362 comes into close contact with the opening edge 162. By doing so, the measuring chamber 16 is shielded from both the storage space 123 and the lead-out space 124, and a closed state is reached. After reaching this sealed state, the switching portion 136 is slightly raised so that the inner peripheral edge portion 1361 separates from the protrusion portion 161 while the outer peripheral edge portion 1362 slides upward while maintaining a close state with the opening edge 162. It moves to reach the ascending state shown in FIG. 11 (b). That is, there is a possibility that a slight internal pressure fluctuation may occur in the measuring chamber 16 due to the momentary rise of the switching portion 136 when the measuring chamber 16 is switched from the closed state to the communicating state communicating only with the lead-out space 124. Such internal pressure fluctuations can be released to the outside of the container body 12 through the derived space 124 and the openly converted nozzle hole 140.

Then, according to the rotation operation of the cap 18, the convex portion 180 reaches the top end position of the guide groove 1212. Therefore, by pulling out the cap 18 upward, the convex portion 180 is pulled out upward from the opening of the top end of the guide groove 1212. (See the left side portion of FIG. 16), the cap 18 can be separated from the container body 12. Next, the container body 12 is turned upside down to be in an inverted state (see the right portion of FIG. 16). As a result, the liquid measured in the measuring chamber 16 is led out to the lead-out space 124, and falls into the nozzle member 14 through the central hole 132. When the shaft portion 152 is pressed against the affected portion (for example, the scalp) H in this inverted state, the elastic arm portions 153, ... Of the spring valve 15 are bent, the valve body 154 is retracted, and the nozzle hole 40 is opened through the concave groove 521. Therefore, the liquid can be poured out to the scalp H and applied.

After use, the fixed quantity pouring container is returned to the upright state, the vertical rib 184 of the cap 18 is fitted into the vertical concave groove 1431 of the nozzle member 14, and the convex portion 180 is inserted into the top end of the guide groove 1212 of the container body 12. When the cap 18 is rotated in the closing rotation direction opposite to the opening cap operation, the cap 18 returns to the original closed cap state. Along with this, the nozzle member 14 and the pipe member 13 also rotate synchronously and return to the lowered state.

According to the above-mentioned quantitative injection container, the same action and effect as those of the first embodiment can be obtained, and usability can be improved by releasing the internal pressure fluctuation by the cap 18. That is, when a predetermined amount of liquid is to be poured out from the container body 12 in which the liquid is stored, the predetermined amount of liquid can be accurately measured and the measured liquid can be accurately measured by simply rotating the cap 18 in the closed cap state in the opening direction. Can be reliably taken out (deriving and pouring). In other words, by simply opening the cap 18, which is absolutely necessary for a container with a cap, weighing and pouring can be performed accurately and reliably, eliminating the need for other special operations. can do. Moreover, if the cap 18 is in the open cap state, it has already been converted into a measurable state by the open cap operation, and the user is in a state where a certain amount of liquid can be poured out and applied. You can grasp it immediately at a glance.

Further, by adopting a combination of the convex portion 180 and the spiral guide groove 1212 as the elevating operation mechanism of the cap 18, or a combination of the convex portion 144 and the spiral guide groove 1211 as the elevating operation mechanism of the nozzle member 14. As compared with the case of adopting a normal screw coupling (for example, screwing with a screw screw), the amount of lifting and lowering for the same rotation operation can be significantly increased, and a reliable operation can be obtained by a simple operation.

Further, when not in use, that is, in the closed cap state in which the cap 18 is put on the container body 12, the pipe member 13 is in the lowered state, so that the lead-out space 124 can be cut off from the storage space 123. Further, in both the process of the pipe member 13 from the lowered state to the raised state and the raised state in which the cap 18 is removed, the inner peripheral edge portion 1361 of the switching portion 136 is brought into close contact with the outer peripheral surface of the protruding portion 161. Alternatively, the lead-out space 124 can be blocked from the storage space 123 by bringing the outer peripheral edge portion 1362 of the switching portion 136 into close contact with the opening edge 162. As described above, the liquid contained and stored in the container body 12 is sealed regardless of whether the container is lowered or raised, and even if the fixed-quantity dispensing container is placed in a state such as lying down instead of being upright. The state can be maintained, and the occurrence of liquid leakage or the like can be avoided.

In addition, even if the internal pressure fluctuation occurs in the measuring chamber 16 during the weighing operation (conversion from the descending state to the rising state of the switching unit 136) by the opening operation of the cap 18, the internal pressure fluctuation is released. Can be done. As a result, even when the measured liquid is poured out, it can be poured out to the scalp or the like by a natural pouring flow. Moreover, the internal pressure fluctuation can be released at the same time by opening the cap 18 without performing a special operation or the like.
