Japanese Patent No. 3759428

  However, in the above-described conventional application container, it is difficult to control the discharge amount of the contents discharged through the discharge hole of the valve member at the application position, and there is room for improvement in improving the discharge accuracy.

  Therefore, the present invention has been made in view of the above-described circumstances, and an object thereof is to provide a coating container capable of improving the discharge accuracy.

In order to solve the above problems, the present invention proposes the following means.
An application container according to the present invention is a container main body in which contents to be applied to an application portion are accommodated, an inner plug member that is attached to a mouth portion of the container main body and has a communication hole communicating with the inside of the container main body, A measuring cylinder member forming a measuring chamber communicating with the inside plug member through the communication hole and the inside of the container main body, and a tip portion projecting outside from the measuring cylinder member and communicating with the measuring chamber. A coating plug having a discharge hole, and a leading end projecting to the outside through the discharge hole and connected to the coating plug, wherein the leading protrusion includes an outer peripheral surface of the leading protrusion and the discharge plug. The metering chamber communicates with the outside through a discharge passage formed between the inner peripheral surface of the hole, the coating plug blocks communication between the metering chamber and the outside, and the metering chamber and the container Weighing position to communicate with the main body and container The container is positioned between the application position where the measurement chamber is located on the bottom side of the container main body in the direction, the communication between the measurement chamber and the container main body is blocked, and the measurement chamber is communicated with the outside. The leading projection is arranged so as to be movable in the axial direction, and the tip projection of the leading projection is elastic toward the bottom side of the container body along the container axial direction while changing the cross-sectional area of the discharge passage. A plurality of nozzles are arranged along the circumferential direction of the discharge hole between the inner peripheral surface of the discharge hole and the outer peripheral surface of the preceding protrusion, and the inner peripheral surface of the discharge hole and the preceding protrusion It is characterized in that an elastic connecting piece for connecting the outer peripheral surface is provided .

With such a feature, when the coating container is in the measuring position and the coating container is placed in an inverted position, for example, with the leading protrusion facing downward, the contents in the container body flow into the measuring chamber through the communication hole. Outflow of contents to the outside is prevented. Therefore, a predetermined amount of contents are weighed in the weighing chamber.
After that, when the application stopper is moved to the application position with the inverted posture, etc., the contents in the measurement chamber are applied through the discharge path formed between the outer peripheral surface of the preceding protrusion and the inner peripheral surface of the discharge hole. It can discharge to a part.
Here, when the tip end surface of the preceding projection is pressed against the application portion in a state where the application plug is at the application position, the tip end surface of the preceding projection is elastically displaced according to the pressing force. Then, the flow volume of the content discharged to a to-be-coated part through a discharge path changes because the flow-path cross-sectional area of a discharge path changes. Thus, the flow rate of the content discharged through the discharge path can be controlled by adjusting the pressing force of the preceding protrusion, that is, the amount of displacement of the leading end surface of the preceding protrusion. As a result, the discharge accuracy can be improved.
In addition, since the tip surface of the preceding protrusion that can be elastically displaced in the container axial direction is pressed against the application portion, the impact, external force, etc. exerted on the application portion during application are alleviated by the cushioning action of the preceding protrusion. . Therefore, it is possible to obtain a soft application feeling, reduce uncomfortableness and uncomfortableness, and perform a comfortable and comfortable application.

In this case, since the elastic connecting piece is provided between the inner peripheral surface of the discharge hole and the outer peripheral surface of the preceding protrusion, the elastic connecting piece is pressed when the tip surface of the preceding protrusion is pressed against the application portion. By elastically deforming, the flow passage cross-sectional area of the discharge path can be changed while elastically displacing the tip surface of the preceding protrusion integrally with the entire preceding protrusion. Thereby, it becomes possible to change the flow-path cross-sectional area of a discharge path stably, and can aim at the further improvement of discharge accuracy.
Moreover, by setting so that the state before the elastic connecting piece is elastically deformed becomes the minimum flow path cross-sectional area, it is possible to suppress liquid leakage from the discharge path in this state.

  There may be provided a restricting portion that engages when the front end surface of the preceding protrusion is elastically displaced in the container axial direction and restricts further elastic displacement of the front end surface.

  In this case, since the restricting portion for restricting the amount of elastic displacement of the leading end surface of the preceding protrusion is provided, excessive displacement of the leading end surface of the preceding protrusion in the container axial direction can be restricted. As a result, it is possible to suppress a large load from being applied to the deformed portion that is deformed in accordance with the elastic displacement of the leading end surface of the leading protrusion, and the flow passage cross-sectional area of the discharge path can be stably changed over a long period of time. Can do.

  The peripheral wall portion of the measuring cylinder member forms an inner peripheral surface of the measuring chamber, and is formed with a main body cylinder portion formed so that the measuring chamber can be visually recognized from the outside, and a larger diameter than the main body cylinder portion, An attached cylinder portion that extends from the outer peripheral surface of the main body cylinder portion toward the bottom side of the container body along the container axial direction, and is attached to at least one of the mouth portion and the inner plug member, The adherend tube part may be located on the bottom side of the container main body along the container axial direction from the bottom surface of the measuring chamber.

  In this case, since the adherend cylinder part is located on the bottom side of the container main body along the container axial direction with respect to the bottom surface of the measurement chamber, the adherend cylinder can be used when visually checking the contents in the measurement chamber through the main body cylinder part. The remaining amount of the contents can be easily confirmed without obstructing visual recognition by the part.

  According to the present invention, it is possible to improve the discharge accuracy.

  A locking cylinder 63 extending downward is disposed on the top wall 62. The locking cylinder 63 is arranged coaxially with the container axis O. The locking cylinder 63 surrounds the leading protrusion 15 from the outside in the radial direction, and the lower end portion of the locking cylinder 63 is fitted in the discharge hole 41. At the lower end portion of the locking cylinder 63, a second locking portion 63a that is detachably locked with the first locking portion 41a of the mounting hole 36 is formed.

  Next, the effect | action of the application | coating container 10 mentioned above is demonstrated. In the following description, a state in which the overcap 16 is attached to the mouth portion 11a of the container body 11 as shown in FIGS. 1 and 2 is an initial state. In the coating container 10 in the initial state, the coating stopper 14 blocks communication between the inside of the measuring chamber 29 and the inside of the container body 11 through the communication hole 21 and communicates the inside of the measuring chamber 29 with the outside through the discharge path 52. It is located at the application position P2.

  In the coating container 10 in the initial state, the screwing between the mouth 11a of the container body 11 and the overcap 16 is released, and the overcap 16 is removed. When the overcap 16 and the container body 11 are relatively rotated in the direction in which the screwing is released, the overcap 16 moves upward with respect to the container body 11 along with the relative rotation. At this time, since the overcap 16 is locked to the coating plug 14 via the locking cylinder 63, the second locking portion 63a, and the first locking portion 41a, the coating cap is moved along with the upward movement of the overcap 16. 14 is raised.

  At this time, as shown in FIG. 3, the application plug 14 is pulled up together with the overcap 16 until the connecting step 44 abuts on the top 34 of the measuring cylinder member 13 and further upward movement is restricted. In this state, when the overcap 16 and the container body 11 are further rotated relative to each other in the direction in which the screwing is released, the overcap 16 moves upward with respect to the application plug 14, thereby The second locking portion 63a gets over each other. As a result, the locking of the overcap 16 and the coating plug 14 is released, and only the overcap 16 moves upward, so that the screwing of the overcap 16 and the container body 11 is released, and the overcap 16 is removed.

  At this time, the seal portion 45 of the coating plug 14 is detached from the outer cylinder 25 of the inner plug member 12, and the communication hole 21 of the inner plug member 12 and the inside of the measuring chamber 29 are the lower end of the seal portion 45 and the outer cylinder 25. Is communicated with the upper end of the. On the other hand, as shown in FIGS. 3 and 4, a portion of the small diameter portion 43 of the coating plug 14 that is located below the through hole 46 is liquid-tightly fitted into the mounting hole 36, and the through hole 46. And the communication between the measuring chamber 29 and the discharge hole 41 are blocked. Thus, immediately after the overcap 16 is removed, the application plug 14 blocks communication between the inside of the measuring chamber 29 through the discharge passage 52 and the outside, and also connects the inside of the measuring chamber 29 and the inside of the container body 11. It is located at a metering position P1 communicating with the hole 21.

  Next, the contents M in the container body 11 are caused to flow into the measuring chamber 29. In a state where the application plug 14 is at the measurement position P1, the application container 10 is set in an inverted posture in which the leading protrusion 15 faces downward. Then, the content M in the container main body 11 flows into the measurement chamber 29 through the communication hole 21. On the other hand, since the communication between the through hole 46 of the coating plug 14 and the inside of the measuring chamber 29 is blocked at the measurement position P1, the inflow of the content M into the discharge hole 41 through the through hole 46 is prevented. ing. As a result, a predetermined amount of the content M is weighed in the weighing chamber 29. In the inverted posture, the upper and lower sides of the application container 10 are inverted, so that the application stopper 14 side along the container axis O direction is the lower side and the container body 11 side is the upper side.

Subsequently, as shown in FIG. 5, the leading protrusion 15 and the application plug 14 are pressed against the application portion S in a state where the application container 10 is maintained in the inverted posture.
At this time, first, the leading end surface of the leading protrusion 15 is pressed against the application portion S, and the leading protrusion 15 is pushed upward. Then, the elastic connecting piece 51 is elastically deformed in the container axis O direction, and the flow path cross-sectional area of the discharge path 52 is increased.

  Thereafter, the application plug 14 is pressed against the application portion S together with the leading protrusion 15. When the application plug 14 is pressed against the portion S to be applied, the application plug 14 moves upward with respect to the measuring cylinder member 13. At this time, first, before the sealing portion 45 of the coating plug 14 is fitted into the outer cylinder 25 of the inner plug member 12, the communication between the through hole 46 of the coating plug 14 and the inside of the measuring chamber 29 is released. Move to the intermediate position P3. In addition, you may comprise so that the interruption | blocking of the communication with the through-hole 46 and the inside of the measurement chamber 29 may be cancelled | released after the seal | sticker part 45 is fitted in the outer cylinder 25. FIG.

Thereafter, as shown in FIG. 6, the application plug 14 is moved to the application position P <b> 2 where the seal portion 45 of the application plug 14 is fitted in the outer cylinder 25 of the receiving portion 24. At this time, the connection stopper 44 of the application plug 14 contacts the inner cylinder 26 of the receiving portion 24 from below, so that the upward movement of the application plug 14 is restricted. Further, when the restricting portions 53 are engaged with each other, further elastic displacement in the container axis O direction of the entire leading protrusion 15 (the front end surface of the leading protrusion 15) is restricted.
When the application plug 14 moves to the application position P <b> 2, the content M in the measuring chamber 29 flows into the discharge hole 41 through the through hole 46. The content M that has flowed into the discharge hole 41 is discharged onto the application portion S through the discharge path 52.

  Here, when the tip end surface of the preceding protrusion 15 is pressed against the portion S to be applied in the state where the application plug 14 is at the application position P2, as shown in FIGS. 6 and 7, the preceding protrusion 15 is in accordance with the pressing force. Is elastically displaced. Then, the flow volume of the content M discharged to the application part S through the discharge path 52 changes because the flow-path cross-sectional area of the discharge path 52 changes. Thereby, the discharge amount of the content M discharged to the to-be-coated part S can be adjusted.

  In addition, the main body cylinder part 33 is formed so that the inside of the measuring chamber 29 can be visually recognized from the outside. Specifically, the main body cylinder part 33 is formed to be transparent or translucent (for example, formed so that visible light can be transmitted). 8, the remaining amount of the contents M in the measuring chamber 29 can be confirmed by once returning the application container 10 to the upright posture as shown in FIG. 8. In the illustrated example, the bottom surface of the measuring chamber 29 (the upper end surface of the outer cylinder 25 of the inner plug member 12) is located above the upper end surface of the adherend cylinder part 32, so The remaining amount of the contents M in the measuring chamber 29 can be easily confirmed without hindering the visibility of the objects M.

As described above, according to the application container 10 according to the present embodiment, the flow path cross-sectional area of the discharge path 52 changes with the displacement of the preceding protrusion 15 in the container axis O direction. By adjusting the pressing force, that is, the amount of displacement of the preceding protrusion 15 (the amount of displacement of the leading end surface of the preceding protrusion 15), the flow rate of the content M discharged through the discharge path 52 can be controlled. As a result, the discharge accuracy can be improved.
In the present embodiment, in the state where the leading end surface of the leading protrusion 15 is not elastically displaced, the flow passage cross-sectional area of the discharge passage 52 is small, and the unexpected outflow of the contents M is inhibited. When the distal end surface of the material is elastically displaced, the flow passage cross-sectional area of the discharge passage 52 increases and the contents M are easily discharged. Therefore, by repeating the elastic displacement and the restoring displacement of the leading end surface of the leading projection 15, the contents M can be dispensed in multiple times.

  In addition, since the tip surface of the preceding protrusion 15 that can be elastically displaced in the container axis O direction is pressed against the application portion S, the impact and external force applied to the application portion S are reduced by the cushioning action of the preceding protrusion 15 during application. Will be. Therefore, it is possible to obtain a soft application feeling, reduce uncomfortableness and uncomfortableness, and perform a comfortable and comfortable application.

Further, since the elastic connecting piece 51 is provided between the inner peripheral surface of the discharge hole 41 and the outer peripheral surface of the preceding protrusion 15, when the tip surface of the preceding protrusion 15 is pressed against the application portion S. By elastically deforming the elastic connecting piece 51, the flow passage cross-sectional area of the discharge passage 52 can be changed while elastically displacing the tip surface of the preceding protrusion 15 integrally with the entire preceding protrusion 15. Thereby, it becomes possible to change the flow path cross-sectional area of the discharge path 52 stably, and the further improvement of discharge precision can be aimed at.
Moreover, by setting the state before the elastic connecting piece 51 to be elastically deformed so as to have the minimum flow path cross-sectional area, it is possible to suppress liquid leakage from the discharge path 52 in this state.

  Furthermore, since the restricting portion 53 that restricts the amount of elastic displacement of the leading end surface of the leading projection 15 is provided, excessive displacement of the leading end surface of the leading projection 15 in the container axis O direction can be regulated. As a result, it is possible to prevent a large load from being applied to the elastic connecting piece 51 (a deformed portion that deforms in accordance with the elastic displacement of the distal end surface of the leading protrusion 15), and the flow path cross-sectional area of the discharge path 52 is increased. It can be changed stably over a period of time.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, when the contents M are applied onto the application portion S using the application container 10 shown in the above embodiment, the application portion is in a state where the tip portion of the leading protrusion 15 is in contact with the application portion S. It is also possible to move the application container 10 with respect to S.

Further, the restriction unit 53 may not be provided.
Moreover, although the structure which provides a clearance gap between the inner peripheral surface of the discharge hole 41 and the outer peripheral surface of the preceding protrusion 15 in the state before elastic deformation is employ | adopted as the elastic connection piece 51, the structure without this clearance gap is employ | adopted. It is also possible.

  In the above-described embodiment, the leading protrusion 15 itself is not deformed, and the connecting portion between the leading protrusion 15 and the application plug 14 is deformed, so that the entire leading protrusion 15 is elastically displaced in the container axis O direction. Accordingly, the tip surface of the leading protrusion 15 is also elastically displaced, but the present invention is not limited to this. For example, a configuration may be employed in which the leading protrusion 15 is formed so as to be elastically deformable, and the leading protrusion 15 itself is deformed so that the tip surface of the leading protrusion 15 is elastically displaced in the container axis O direction.

  In addition, the leading protrusion 15 can be appropriately changed to another form continuously connected to the coating plug 14. From the viewpoint of reducing the number of parts, it is preferable that the coating plug 14 and the leading projection 15 are integrally formed as in the above-described embodiment. However, the leading projection 15 is formed separately from the coating plug 14, and these are formed. It is also possible to assemble them together.

  The container body 11 is not limited to a shape having a self-supporting bottom as shown in the above-described embodiment, and can be changed as appropriate, and various cross-sectional shapes and the like of the container can be adopted.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
