The coating container of Patent Document 1 basically allows the liquid in the container body to flow down to the mouth cylinder portion through the liquid passage hole in an inverted state, and the liquid supplied from the mouth cylinder portion is used on the coating surface. It is used by spreading it on the surface to be coated. If a coating portion such as a sponge is attached to the coating surface, the liquid can be contained in the coating portion in an inverted state and used as an upright state, but only the amount contained can be applied. Further, when the product is used in the initial state, even if it is suddenly tried to be applied in an upright state, the liquid cannot be applied because the liquid has not penetrated into the applied portion.

An object of the present invention is to provide a coating container that is easy to use in both an upright state and an inverted state.

The first means is a container body 2 that erects the mouth and neck 6 from the squeezable body 4.
A fitting peripheral wall 10 fitted to the mouth neck 6 is provided on the outer peripheral portion, and a spout 22 is opened in a top wall 16 continuous with the fitting peripheral wall 10, and the contents are covered around the spout 22. A cap member 8 having a coating surface 28 for coating on the coating material,
It has a tubular peripheral wall 32 supported inside the mouth neck 6, and a partition wall 36 facing the back surface of the top wall 16 of the cap member 8 is stretched inside the tubular peripheral wall 32, and a part of the partition wall 36. A holding cylinder member 30 having a pipe holding hole 42 communicating with the spout 22 via a communication passage C.
It is provided with an upright liquid supply pipe 48 that is fitted into the pipe holding hole 42 and hangs down to the lower part of the container body 2.
In addition, in the upside-down coating container, the holding cylinder member 30 is formed with an auxiliary passage A that opens from the lower surface of the partition wall 36 into the communication passage C and allows the liquid to pass through during inversion.
An obstruction member 50 having an obstruction plate 52 covering the upper part of the spout 22 forming portion was attached to the cap member 8.

In this means, as shown in FIG. 1, an obstruction member 50 having a spout 22 opened in a part of the top wall 16 of the cap member 8 and an obstruction plate 52 covering the upper part of the spout 22 forming portion is provided. It is proposed to attach it to the cap member 8. As a result, even if the user excessively squeezes the body 4, the contents are dispersed and discharged along the back surface of the baffle plate 52 in all radial directions, so that the contents pop out from the spout 22 to the outside. Can be prevented.
Further, a partition wall 36 is stretched inside the tubular peripheral wall 32 supported inside the mouth neck 6, and a pipe holding hole that communicates with the spout 22 through a communication passage C in a part of the partition wall 36. A holding cylinder member 30 that opens 42 is provided, and an upright liquid supply pipe 48 that is fitted into the pipe holding hole 42 and hangs down to the lower part of the container body 2 is provided, and the holding cylinder member 30 is provided with the partition wall. An auxiliary passage A is formed which opens from the lower surface of the 36 into the communication passage C and allows the passage of liquid when inverted. According to this configuration, as shown in FIG. 6, in the inverted state, when the body 4 is squeezed, the liquid in the container is supplied from the spout 22 via the auxiliary passage A and the communication passage C.
Further, in the upright state, as shown in FIG. 7, by squeezing the body portion 4, the air in the upper part of the container body 2 is first exhausted from the injection port 22 through the auxiliary passage A and the communication passage C, and this air flow. The liquid is sucked up to the confluence e2 by making the communication passage C negative pressure, and the contents are supplied from the spout 22 by continuing to squeeze the body portion 4.

The "holding cylinder member" is a member in which a pipe holding hole 42 for holding a liquid supply pipe is opened in a partition wall 36 continuous with the cylinder peripheral wall 32, and is supported inside the mouth and neck. The pipe holding hole 42 communicates with the spout 22 via the communication passage C, and an auxiliary passage A that opens from the lower surface of the partition wall 36 into the communication passage C is formed.
"Supported inside the mouth and neck 6" includes not only a structure supported by the mouth and neck 6 but also a structure supported by the cap member 8.
The "auxiliary passage" also serves as a passage for the contents in an inverted state and a passage for air in an upright state.
The "obstructing member" is a means for adjusting the direction of the flow of the contents discharged from the spout 22, and uses an obstructing plate 52 that covers the upper part of the place where the spout 22 is formed, and goes straight up from the spout. I try not to pop out. By providing an obstructing member, it is possible to regulate the vigorous discharge (spouting) of the liquid upward and to discharge the liquid in the radial direction. The obstructing member may be configured as a valve body of the liquid discharge valve.

The second means has the first means, and the obstruction member 50 passes the contents through the lower part of the support rod 56 hanging from the central portion of the elastic obstruction plate 52 into the spout 22. A gap g, which is an air passage, was formed between the lower surface of the baffle plate 52 and the upper surface of the top wall 16 around the spout 22 while being inserted and locked as possible.

In this means, as shown in FIG. 2, the obstruction member 50 inserts the lower portion of the support rod 56 hanging from the central portion of the elastic obstruction plate 52 into the spout 22 so that the contents can pass through. .. Further, as shown in FIG. 3, a gap g, which is an air passage, is formed between the lower surface of the baffle plate 52 and the upper surface of the top wall 16 portion around the spout 22.
According to this configuration, by squeezing the body 4 in an upright state, an air flow from the upper part of the container 2 through the auxiliary passage A and the communication passage C can be quickly generated, and the contents up to the confluence. It is possible to ensure the suction of objects. Therefore, the liquid can be accurately discharged even though the configuration is simpler than that of the pump mechanism having a built-in suction valve and discharge valve.

The third means has a first means or a second means, and the partition wall 36 has an inflow port e1 to the auxiliary passage A, and the lower surface of the partition wall is the outer edge of the partition wall 36. The liquid collection surface S has a substantially tapered shape and is inclined upward and inward from the portion to the inflow port e1.

In this means, the lower surface of the partition wall 36 is a substantially tapered liquid collecting surface S that inclines upward and inward from the outer edge portion of the partition wall 36 to the inflow port e1, and as a result, when the contents are low. , As shown by the alternate long and short dash line in FIG. 6, the contents can be guided along the liquid collecting surface S to the inflow port e1 of the auxiliary passage A.

According to the invention according to the first means, since the obstruction member 50 provided with the obstruction plate 52 covering the upper part of the spout 22 forming portion of the cap member 8 is attached to the cap member 8, the user attaches the container body 2 to the container body 2. Even if it is made excessively strong, the direction of the contents discharged vigorously from the spout 22 can be changed to prevent the contents from being scattered outward as it is, and it is easy to use even in an upright state.
According to the invention according to the second means, since a gap g, which is an air passage, is formed between the lower surface of the baffle plate 52 of the baffle member 50 and the upper surface of the top wall 16 around the spout 22, the state is upright. When the container body 2 is squeezed with, the air inside the container flows from the auxiliary passage A to the outside through the gap g, and the liquid inside the container flows to the outside through the liquid supply pipe 48 due to the negative pressure generated by this air flow. Since it can be discharged, it is easy to use in an upright position.
According to the invention according to the third means, the partition wall 36 has an inflow port e1 to the auxiliary passage A, and the lower surface of the partition wall is inward from the outer edge portion of the partition wall 36 to the inflow port e1. Since the liquid collecting surface S has a substantially tapered shape that is inclined in the direction, the contents can be discharged to the end even if the remaining amount of the contents in the container body 2 becomes small, which is convenient.

1 to 7 show a coating container according to an embodiment of the present invention. The coating container is formed of a container body 2, a cap member 8, a holding cylinder member 30, a liquid supply pipe 48, an obstructing member 50, and a lid 60. These members can be formed of, for example, synthetic resin.

The container body 2 stands up from the squeezable body 4 to the mouth and neck 6 via the shoulders. The upper part of the mouth neck 6 forms a small diameter portion 6a. A fitting groove portion 7 is provided around the outer surface of the small diameter portion 6a. Further, a screw portion is formed on the outer surface of the mouth neck portion excluding the small diameter portion 6a.

The cap member 8 has a fitting peripheral wall 10 fitted to the mouth and neck portion 6 on the outer peripheral portion thereof, and a top wall 16 continuous with the upper portion of the fitting peripheral wall 10.
The fitting peripheral wall 10 of the present embodiment is formed in a double tubular shape including an inner peripheral wall 10a fitted to the inner surface of the mouth neck 6 and an outer peripheral wall 10b fitted to the outer surface of the mouth neck 6. ..
In the illustrated example, the outer peripheral wall 10b hangs down from the outer surface of the inner peripheral wall 10a via the connecting wall portion 10c. The outer peripheral wall 10b is fitted to the outer surface of the small diameter portion 6a, and the fitting ridge 12 attached to the lower inner surface of the outer peripheral wall 10b is fitted into the fitting groove portion 7. Further, an engaging groove portion 14 is provided around the upper inner surface of the outer peripheral wall 10b. However, these configurations can be changed as appropriate.
The top wall 16 is continuous with the upper end of the outer peripheral wall 10b. The top wall 16 shown in the figure is formed in a dome shape, but the shape thereof can be changed as appropriate.
A spout 22 is opened in a part of the top wall 16 (the central portion in the illustrated example). In a preferred illustrated example, the vicinity of the spout 22 is formed in the recessed portion 18, and the spout 22 is opened at the bottom thereof. As shown in FIG. 2, the bottom surface 19 of the recessed portion 18 shown in the drawing is formed by an annular upper bottom surface 19a and an inner lower bottom surface 19b, and a spout 22 is formed in the lower bottom surface 19b. As shown in FIG. 4, contact ribs 20 having a flat upper surface are formed in the radial direction at a plurality of locations (three locations in the illustrated example) in the circumferential direction of the lower bottom surface 19b. Further, the claw portion 24 protrudes inward from the mouth edge of the spout 22. The claw portion 24 of the illustrated example is arranged at a position corresponding to the contact rib 20, but it is not always necessary to have such a configuration.
A communication tube portion 26 hangs down from the periphery of the spout 22. The inner surface of the illustrated communication tube portion 26 is formed as a tapered surface having a large diameter at the lower end.
Further, the outer surface of the top wall portion between the recessed portion 18 and the inner peripheral wall 10a is formed on the coating surface 28 for applying the content liquid to the object to be coated.

The holding cylinder member 30 is a bottomed cylindrical member supported inside the mouth and neck portion 6, and is supported via the cap member 8 in the illustrated example, but is supported by the mouth and neck portion 6. It doesn't matter.
The holding cylinder member 30 of the present embodiment has a cylinder peripheral wall 32 fitted to the inner surface of the inner peripheral wall 10a, and an engaging rib 34 attached to the upper outer surface of the tubular peripheral wall 32 is fitted into the engaging groove portion 14. I'm matching.
The holding cylinder 38 stands up from the lower part of the cylinder peripheral wall 32 via the partition wall 36.
The partition wall 36 is inclined upward and inward from the lower part of the cylinder peripheral wall 32, and the lower surface of the partition wall 36 is a liquid collecting surface S which is a tapered surface having a small diameter at the upper end. The liquid collecting surface S plays a role of collecting liquid to the inflow port e1 of the auxiliary passage A described later in an inverted state.
The holding cylinder 38 is a member whose cylinder hole is a pipe holding hole 42. In the holding cylinder 38 of the illustrated example, the upper end portion is a small inner diameter portion 40, and the cylinder hole in the portion below the small inner diameter portion 40 is a pipe holding hole 42. Further, the holding cylinder 38 is provided with a vertical groove 44 that opens downward from the lower half of the small inner diameter portion 40.
An extension cylinder portion 46 having a larger inner diameter than the holding cylinder 38 extends from the upper end of the holding cylinder 38. The communication cylinder portion 26 is liquid-tightly fitted to the inner surface of the extension cylinder portion 46.

The upper end of the liquid supply pipe 48 is fitted into the pipe holding hole 42 and hangs down from the bottom of the container body 2. An auxiliary passage A that serves as a liquid passage in an inverted state and an air passage in an upright state is formed between the upper end of the liquid supply pipe 48 and the holding cylinder 38. The auxiliary passage A has an inflow port e1 that opens on the lower surface of the partition wall 36 and a confluence e2 that opens on the inner surface of the small inner diameter portion 40.

The obstruction member 50 is a means for preventing the liquid from jumping directly upward from the spout 22 in the upright state of the coating container, and has an obstruction plate 52 that obstructs the momentum of the liquid, and has a lower surface of the obstruction plate 52. A support rod 56 hanging from the central portion is locked in the spout 22.
Further, in the present embodiment, the obstruction member 50 is made of an elastic material and has a function as a valve body of the liquid discharge valve V.

The baffle plate 52 covers the spout 22 and the top wall portion around the spout 22, and changes the direction of the liquid flowing upward in the spout 22 to the upper side, in other words, to the coating surface 28 side. It is configured.
In the present embodiment, the outer peripheral plate portion 52b of the baffle plate 52 is in contact with or close to the top wall portion, and the baffle plate 52 is elastically deformed upward by the hydraulic pressure in the spout 22 to open and hydraulic pressure. The baffle plate 52 is elastically restored by the elimination of the above, and a liquid discharge valve V that regulates the outflow of the contents is formed.
It is also possible to provide a gap in the liquid discharge valve that regulates the outflow of the contents so that air having a lower viscosity than the liquid can pass through. In the illustrated example, as shown in FIG. 3, a gap g as an air passage is provided between the outer peripheral plate portion 52b of the baffle plate 52 and the top wall portion around the spout 22. With this configuration, when the body 4 is squeezed in an upright state, an air flow passing through the auxiliary passage A, the communication passage C, and the gap g is quickly generated from the inside of the container body 2, and the pressure is reduced by the generation of the air flow. The liquid is sucked through the liquid supply pipe 48.
In the baffle plate 52 of a suitable illustrated example, the inner peripheral plate portion 52a is thicker than the outer peripheral plate portion 52b, and the lower surface of the inner peripheral plate portion 52a is lower than the lower surface of the outer peripheral plate portion 52b. Then, the lower surface of the outer peripheral plate portion 52b is brought close to the upper bottom surface 19a of the recessed portion 18, and the inner peripheral plate portion 52a is brought into contact with the upper surface of the contact rib 20.

As shown in FIG. 3, the support rod 56 is inserted into the spout 22 with a play m, which is a fluid passage, between the support rod 56 and the mouth surface, and is locked. In a preferred illustrated example, the claw portion 24 is in contact with the upper outer surface of the support rod 56. A retaining rib 56a is provided around the lower outer surface of the support rod 56. The retaining rib 56a is formed so as to get over the claw portion 24 when the support rod 56 is inserted into the mouth neck portion 6 and to be locked to the lower surface of the claw portion 24.

As shown in FIG. 1, the lid body 60 is formed by stretching a lid top wall 64 on the upper surface of a lid peripheral wall 62 fitted (screwed in the illustrated example) to the mouth neck portion 6. A seal plate 66 is attached to the back surface of the lid top wall 64, and the upper end of the recess 18 is liquid-tightly closed by the seal plate 66. In the illustrated example, the upper half portion 62b of the lid peripheral wall 62 is formed to have a smaller diameter than the lower half portion 62a.

In the above configuration, in the state of FIG. 1, the liquid discharge valve V is closed, and even if the coating container is accidentally tilted, leakage of the liquid from the spout 22 is restricted.
When the coating container is used in an inverted state, as shown in FIG. 6, when the coating container is turned upside down, the liquid moves inside the container body 2 toward the mouth and neck 6, so that the body 4 is moved in this state. When squeezed, the liquid reaches the inside of the spout 22 through the auxiliary passage A and the communication passage C, and the baffle plate 52 is elastically deformed outward by the liquid pressure to open the liquid discharge valve V. As a result, the liquid flows out to the coated surface 28 side along the back surface of the baffle plate 52. Then, the liquid can be applied by rubbing the coating surface 28 to which the liquid is attached to the object to be coated. When the squeezing of the body portion 4 is released, the outside air enters the container body 2 through the gap g, and the negative pressure of the container body 2 is eliminated.
When the coating container is used in an upright state, the body 4 may be suddenly squeezed in the upright state shown in FIG. 7 without being once inverted as in the conventional container. As a result, first, the air in the upper part of the container body 2 is exhausted from the gap g, which is an air passage, via the auxiliary passage A and the communication passage C. The air flow creates a negative pressure in the communication passage C, so that the liquid is sucked up to the confluence e2. Further, when the body portion 4 is continuously squeezed, the liquid in the body portion 4 is pushed up through the liquid supply pipe 48 and the communication passage C, and flows out from the spout 22 to the coating surface 28 side along the back surface of the baffle plate 52. As in the inverted state, the coating surface can be rubbed against the object to perform the coating operation, and when the squeezing of the body 4 is released, the outside air enters the container body through the gap g.
In both the inverted and upright states, the liquid flowing through the spout 22 collides with the baffle plate 52, turns to the coated surface 28 side, and is dispersed and discharged in all radial directions, so that the user has an excess of the body. Even if it is strongly squeezed, it is possible to prevent the liquid from rushing out in the opening direction of the spout 22.
Further, since the liquid discharge valve V is provided as described above, in the application in the inverted state, the contents are not discharged simply by setting the coating container in the inverted position. Further, since the contents are discharged by the amount of pressing the body 4 of the container body, excessive discharge of the contents is suppressed, and it is easy to discharge the required amount of contents by adjusting the degree of pressing. Is. As a result, usability in an inverted state can be improved.
