Description

The present invention relates to a compact container.

A cosmetics storage container including a medium plate container for storing cosmetics is known (see, for example, Patent Document 1). In the cosmetic storage container of Patent Document 1, the upper surface of the medium plate container is covered with a net.

Japanese Unexamined Patent Publication No. 2003-93145

In the conventional cosmetics storage container described above, by pressing the net covering the middle plate container with a puff or the like, the cosmetics are exuded through the mesh of the net and discharged to the outside. However, in this case, the discharge amount is likely to change depending on the force applied when pressing the net, and it is not easy to discharge the cosmetic amount in a desired amount.

The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a compact container capable of more accurately discharging a desired amount of contents.

In order to solve the above problems, in the compact container according to one aspect of the present invention, the inner container in which the contents are housed and the inside of the inner container are sealed, and a communication hole communicating with the inner container is formed. A discharge space provided above the inner lid and communicating with the communication hole is defined between the inner lid and the inner lid, and the contents are discharged by communicating with the communication space. The inner lid in which the hole is formed, the first valve body that switches the communication between the communication hole and the communication space, and the cutoff thereof, and the second valve that switches the communication between the discharge hole and the communication space and the cutoff thereof. The inner lid comprises a body and an outer shell having a bottomed tubular bottom member for accommodating the inner container, the inner lid, the inner lid, the first valve body, and the second valve body. Is provided with an operation unit that defines the communication space and is formed so as to be elastically deformable, and that increases or decreases the internal pressure of the communication space by elastically deforming. When ascended, the first valve body cuts off the communication between the communication hole and the communication space, and the second valve body communicates the discharge hole and the communication space, and the operation unit moves upward. When the internal pressure of the communication space drops due to movement, the second valve body cuts off the communication between the discharge hole and the communication space, and the first valve body connects the communication hole and the communication space. In the communication space, a guide member located between the communication hole and the discharge hole, a space below the guide member, and a space above the guide member are communicated with each other. When the passage and the passage are arranged and the direction intersecting the central axis is the radial direction in a plan view seen from the direction along the central axis of the outer shell, the guiding member has passed through the communication hole. It has a substantially circular plate-shaped portion in a plan view that guides the flow of the contents in the radial direction toward the communication passage.

According to the above aspect, when the operation unit moves downward to increase the internal pressure of the communication space, the first valve body cuts off the communication between the communication hole and the communication space, and the second valve body is the discharge hole. And the communication space. Further, when the operation unit moves upward to lower the internal pressure of the communication space, the second valve body cuts off the communication between the discharge hole and the communication space, and the first valve body connects the communication hole and the communication space. To communicate. Therefore, the user pushes down the operation part and releases the push-down to elastically deform the operation part to increase or decrease the internal pressure of the communication space, thereby making the inside of the communication space negative and inside the inner container. It is possible to flow the contents of the above into the communication space and fill the communication space with the contents. In this state, if the operation unit is pushed down to increase the internal pressure of the communication space, the contents can be discharged from the discharge hole by the amount corresponding to the increase of the internal pressure of the communication space.
In the communication space, a guide member and a communication passage for communicating the spaces above and below the guidance member are arranged, and the contents flowing into the communication space from the communication hole are radial by the guidance member. Guided to the passageway. In this way, instead of directing the contents directly from the communication hole to the discharge hole, the contents are detoured in the radial direction by the guiding member and then directed toward the discharge hole, so that the contents are directed to almost the entire area in the communication space. It is possible to spread it widely over the entire area, and it is possible to prevent the formation of air pools in the communication space. Therefore, for example, it is possible to prevent the discharge amount of the contents from becoming unstable due to the expansion and contraction of the air pool in the communication space due to the temperature change or the unexpected discharge of air together with the contents, which is desired with higher accuracy. It is possible to discharge the contents of the above amount.

Wherein said guide member includes a facing portion facing in the vertical direction to the communication hole, anda the plate-like portion extending radially outward from said opposed portion, the lower surface of the plate-like portion , A groove or rib extending in the radial direction is formed, and the communication passage may be located on the radial outer side of the plate-shaped portion.

In this case, the flow of the contents passing through the communication hole hits the facing portion of the guiding member and is dispersed in the radial direction. Further, the flow of the contents is smoothly guided to the communication passage located on the radial outer side of the plate-shaped portion by the groove or rib formed on the lower surface of the plate-shaped portion. In this way, by directing the contents outward in the radial direction in the communication space and then introducing the contents into the discharge hole, it is possible to more reliably suppress the formation of an air pool at the outer end portion in the radial direction in the communication space. be able to.

Further, the guiding member may be formed so as to be elastically deformable or elastically displaceable downward, and may give an upward urging force to the operating portion that has moved downward.

In this case, the guiding member assists the elastically deformed operating portion to be restored and deformed when the pressing of the operating portion is released. In this way, by stably returning the operation unit to the position before pushing down by the upward urging force of the guiding member, the contents are stably sucked from the inner container into the communication space, and then when the operation part is pushed down. It is possible to stabilize the discharge amount of the contents of.

Further, the guide member has the plate-like portion facing in the vertical direction to the operation unit, the upper surface of the plate-shaped portion, a groove or rib extending in a radial direction may be formed.

In this case, the flow path of the contents from the continuous passage to the discharge hole can be secured by the groove or rib formed on the upper surface of the plate-shaped portion. In particular, when the guiding member urges the operating portion that has moved downward upward, even if the plate-shaped portion and the operating portion are in close contact with each other, the flow path of the contents can be secured. Therefore, the contents can be discharged more stably.

According to the above aspect of the present invention, it is possible to provide a compact container capable of more accurately discharging a desired amount of contents.

The material of the operation unit 73 is, for example, a soft material such as elastomer, nitrile rubber, butyl rubber, silicon rubber, soft polyethylene, urethane and the like (hereinafter, simply referred to as “elastomer and the like”). In consideration of chemical resistance to the contents, for example, PP that is elastically deformable and relatively soft, polyethylene terephthalate (PET) formed into a thin wall, or the like may be used as the material of the operation unit 73. The operating portion 73 is softer than the mounting ring 57, and the mounting ring 57 is harder than the operating portion 73.

An inner groove portion 73b and an outer groove portion 73c that are recessed upward are formed on the lower surface of the operation portion 73. The inner groove portion 73b is located on the inner peripheral edge portion of the operation portion 73, and the outer groove portion 73c is located on the outer peripheral edge portion of the operation portion 73. Therefore, the operating portion 73 is easily deformed with the inner groove portion 73b and the outer groove portion 73c as fixed ends. The inner groove portion 73b and the outer groove portion 73c are formed in an annular shape centered on the container shaft O in a plan view.

A protrusion 74 that protrudes downward is formed in a portion of the operation portion 73 between the inner groove portion 73b and the discharge hole 14a. A plurality of protrusions 74 are formed at intervals in the circumferential direction. Each protrusion 74 is in contact with or close to the plate-shaped portion 81 of the guide member 80, which will be described later, from above. The portion of the top wall member 70 adjacent to the outer groove portion 73c on the outer side in the radial direction is in contact with or in close contact with the annular protrusion 54b.
When the operating portion 73 is pressed, the operating portion 73 is supported by the annular projection 54b, and the protrusion 74 abuts on the plate-shaped portion 81. Then, in this state, the operating portion 73 is elastically deformed in the vertical direction so that the inner groove portion 73b and the outer groove portion 73c are fixed ends.

The plate-shaped portion 81 is formed in a substantially circular shape in a plan view and is fitted in the annular projection 54b. Further, as shown in FIGS. 3A and 3B, a notch 81a is formed on the outer peripheral portion of the plate-shaped portion 81. Therefore, a gap is provided between the notch 81a and the annular projection 54b, and this gap functions as a continuous passage R. The communication passage R is located on the radial outer side of the plate-shaped portion 81.

In the present embodiment, a plurality (four) cutout portions 81a are formed at equal intervals in the circumferential direction, and each cutout portion 81a forms a continuous passage R. That is, in the present embodiment, a plurality of (four) communication passages R are formed at equal intervals in the circumferential direction. For example, a through hole or a slit that penetrates the plate-shaped portion 81 in the vertical direction Z may be formed, and this through hole or the like may be used as the communication passage R.

As shown in FIGS. 3A to 3C, a groove 81b that is recessed upward and extends in the radial direction is formed on the lower surface of the plate-shaped portion 81. In the present embodiment, a plurality of (four) grooves 81b extend radially (cross-shaped) from the central portion (opposing portion 82) of the plate-shaped portion 81. The radial inner end of each groove 81b is open toward the lower side of the facing portion 82, and the radial outer end of each groove 81b is open toward the notch 81a (communication passage R). .. As a result, each groove 81b communicates the space below the facing portion 82 with the communication passage R (see FIG. 2).
The lower surface of the plate-shaped portion 81 in the present embodiment is in contact with or close to the upper surface of the connecting ring portion 55 of the inner lid 13. Even if the plate-shaped portion 81 and the connecting ring portion 55 are in close contact with each other, the groove 81b secures a flow path for the contents from the communication hole 56 to the communication passage R.

The facing portion 82 is located at the radial center portion of the guide member 80, and protrudes upward from the plate-shaped portion 81. The upper surface and the lower surface of the facing portion 82 are formed in a curved surface shape with a protrusion facing upward, and are arranged coaxially with the container shaft O. The facing portion 82 faces the discharge hole 14a and the second valve body 14b in the vertical direction Z. The second valve body 14b is in contact with the upper surface of the facing portion 82.

As shown in FIG. 3B, a plurality (four) legs 83 are formed at equal intervals in the circumferential direction. Each leg portion 83 is located on the radial outer side of the facing portion 82 and on the radial inner side of the radial inner end portion of the groove 81b. As shown in FIG. 2, each leg 83 is in contact with or close to the valve cylinder 84 of the first valve body 15 from above. The gap between the leg portions 83 adjacent to each other in the circumferential direction becomes a flow path of the contents from the communication hole 56 to the communication passage R through the groove 81b.

Next, the operation of the compact container 10A in the present embodiment will be described.

When the compact container 10A is in an unused state, the contents are contained only in the accommodating space 45, and the connecting space S is filled with, for example, air.
The user operates the push piece 37 to open the lid member 22 of the outer shell body 11. Next, the operation unit 73 is pressed from above and elastically deformed so as to be recessed downward. At this time, the operating portion 73 is elastically deformed downward so that the inner groove portion 73b and the outer groove portion 73c are fixed ends. When the operation unit 73 is elastically deformed downward, the volume of the communication space S becomes small, so that the internal pressure of the communication space S increases. Then, the second valve body 14b is elastically deformed upward due to the internal pressure of the communication space S to open the discharge hole 14a, and a part of the air in the communication space S is discharged to the outside from the discharge hole 14a. In this way, the second valve body 14b closes the discharge hole 14a so as to be openable.

Further, when air or contents are discharged from the discharge hole 14a and the internal pressure of the communication space S drops, the second valve body 14b is restored and deformed and comes into contact with the facing portion 82, and the discharge hole 14a is closed again. Therefore, the second valve body 14b also functions as a check valve for suppressing the backflow of the contents or the outside air discharged from the discharge hole 14a into the communication space S. That is, the second valve body 14b allows the flow of the contents or the air through the discharge hole 14a from the connecting space S to the outside, and blocks the flow of the contents or the air from the outside to the connecting space S.

When the pressing force applied to the operation unit 73 is released, the elastically deformed operation unit 73 is restored and deformed to its original state. As a result, the volume of the connecting space S increases, and the pressure inside the connecting space S becomes negative. At this time, since the discharge hole 14a is closed by the second valve body 14b, air is suppressed from entering the communication space S from the outside. On the other hand, when the communication space S becomes a negative pressure, an upward force acts on the valve body 85 of the first valve body 15. As a result, the valve body 85 is elastically displaced upward so that the communication hole 56 and the communication space S communicate with each other, and the contents in the accommodation space 45 are sucked into the communication space S through the communication hole 56. In this way, when the operation unit 73 moves upward and the internal pressure of the communication space S drops, the second valve body 14b cuts off the communication between the discharge hole 14a and the communication space S, and the first valve body 15 Communicates the communication hole 56 and the communication space S.

When the elastic deformation and the restoration deformation of the operation unit 73 described above are repeatedly performed, the air in the communication space S is discharged to the outside, and the contents are filled in the communication space S. Since the inner container 12 has flexibility, the volume is reduced and deformed as the contents flow out to the communication space S or the like through the communication hole 56. As a result, even when the contents flow into the communication space S or the like and the total amount of the contents in the accommodation space 45 is reduced, the contents can be stably sent from the accommodation space 45 to the communication space S. It is possible.

When the operating portion 73 is elastically deformed downward while the connecting space S is filled with the contents, the contents in the connecting space S exert an upward pressure on the second valve body 14b. When the pressure in the communication space S due to the contents reaches a predetermined magnitude, the second valve body 14b is elastically deformed upward, the discharge hole 14a is opened, and the contents are discharged from the discharge hole 14a.

By the above action, the user can discharge the contents by repeatedly pressing and releasing the operation unit 73. Since the contents are discharged to the inside of the raised portion 62, the raised portion 62 suppresses the contents from hanging from the upper surface of the inner lid 14. The user can wipe the upper surface of the inner lid 14 with a puff P or the like, attach the contents to the puff P or the like, and use the inner lid 14.

By the way, when the contents are filled in the communication space S, it is conceivable that an air pool is generated in the communication space S. In particular, when the communication hole 56 and the discharge hole 14a are arranged in the vicinity of the container shaft O as in the present embodiment, an air pool is likely to occur at the radial outer end portion of the communication space S. If there is an air pool in the connecting space S and the air pool expands due to, for example, a temperature change, the contents may be suddenly discharged from the discharge hole 14a without pressing the operation unit 73. be. Alternatively, the expansion and contraction of the air pool may cause variations in the discharge amount of the contents when the operation unit 73 is pressed. Alternatively, when the operation unit 73 is pressed, air is discharged together with the contents, so that the discharge amount of the contents may fluctuate.

Therefore, in the present embodiment, the guide member 80 located between the communication hole 56 and the discharge hole 14a is provided in the communication space S, and the communication passage R for communicating the spaces above and below the guide member 80 is formed. ing. Then, the contents flowing into the communication space S from the communication hole 56 are guided in the radial direction by the guiding member 80 and head toward the communication passage R. In this way, instead of directing the contents directly from the communication hole 56 to the discharge hole 14a, the contents are directed to the discharge hole 14a after being detoured in the radial direction by the guiding member 80, so that the contents can be directed to the discharge hole 14a. It is possible to spread it widely over almost the entire area in S, and it is possible to suppress the formation of air pools in the communication space S. As a result, it is possible to suppress the variation in the discharge amount of the contents due to the air pool, and it is possible to more accurately discharge the desired amount of the contents.

Further, the facing portion 82 faces the communication hole 56 in the vertical direction, the radial inner end portion of the groove 81b opens toward the lower side of the facing portion 82, and the radial outer end portion of the groove 81b is the communication passage R. It is open toward. With this configuration, the flow of the contents passing through the communication hole 56 hits the facing portion 82 and is dispersed in the radial direction. Then, the flow of the contents is smoothly guided by the groove 81b to the communication passage R located on the radial outer side of the guiding member 80. In this way, by directing the contents outward in the radial direction in the communication space S and then introducing the contents into the discharge hole 14a, it is possible that an air pool is generated at the outer end portion in the radial direction in the communication space S. It can be surely suppressed.

Further, since the guide member 80 is arranged in the communication space S, the internal volume of the communication space S is reduced. This makes it possible to quickly fill the communication space S with the contents from an unused state. Further, in a state where the contents are not discharged even if the operation unit 73 is pressed, such as when the remaining amount of the contents in the accommodation space 45 is exhausted, the amount of the contents remaining in the communication space S can be reduced. can. That is, it becomes possible to use up more contents.

(Second Embodiment)
Next, the second embodiment according to the present invention will be described, but the basic configuration is the same as that of the first embodiment. Therefore, the same reference numerals are given to the same configurations, the description thereof will be omitted, and only the different points will be described.
In the compact container 10B of the present embodiment, the shape of the guiding member is different from that of the first embodiment.

As shown in FIG. 4, the guide member 90 of the present embodiment faces the plate-shaped portion 91 extending in a plane orthogonal to the container axis O and the communication hole 56 with the first valve body 15 interposed therebetween in the vertical direction. It has a portion 92, an outer cylinder portion 93 that surrounds the plate-shaped portion 91 from the outside in the radial direction, and a leg portion 95 that projects downward from the facing portion 92.

The facing portion 92 is located at the radial center portion of the guide member 90, and protrudes upward from the plate-shaped portion 91. The upper surface and the lower surface of the facing portion 92 are formed in a curved surface shape with a protrusion facing upward, and are arranged coaxially with the container shaft O. The facing portion 92 faces the discharge hole 14a and the communication hole 56 in the vertical direction Z. The second valve body 14b is in contact with the upper surface of the facing portion 92.

As shown in FIG. 5, a plurality of slits 94a extending in the circumferential direction are formed between the plate-shaped portion 91 and the outer cylinder portion 93. These slits 94a are arranged so as to form a plurality (three) connecting portions 94 between the plate-shaped portion 91 and the outer cylinder portion 93. The plate-shaped portion 91 and the outer cylinder portion 93 are connected by a plurality of connecting portions 94 extending in the circumferential direction. The plate-shaped portion 91 can be elastically displaced with respect to the outer cylinder portion 93 by elastically deforming the plurality of connecting portions 94.

In the present embodiment, the slit 94a functions as a communication passage R for communicating the space below the guide member 90 and the space above the guide member 90 in the communication space S. The communication passage R (slit 94a) is located on the radial outside of the plate-shaped portion 91 and on the radial inside of the outer cylinder portion 93.

The plate-shaped portion 91 extends radially outward from the facing portion 92 and faces the operating portion 73 in the vertical direction. As shown in FIG. 5, the plate-shaped portion 91 is formed in a substantially circular shape in a plan view. A groove 91a that is recessed downward and extends in the radial direction is formed on the upper surface of the plate-shaped portion 91. In the present embodiment, a plurality of (four) grooves 91a extend radially (cross-shaped) from the central portion (opposing portion 92) of the plate-shaped portion 91. The radial inner end of each groove 91a is open toward the upper surface of the facing portion 92, and the radial outer end of each groove 91a is open toward the slit 94a (communication passage R). As a result, each groove 91a communicates the communication passage R with the discharge hole 14a.

As shown in FIG. 4, the lower surface of the operation unit 73 of the present embodiment is a flat surface, and the upper surface of the plate-shaped portion 91 is in contact with or close to the lower surface of the operation unit 73. Even if the plate-shaped portion 91 and the operating portion 73 are in close contact with each other, the groove 91a secures a flow path for the contents from the communication passage R to the discharge hole 14a.

As shown in FIG. 6, a plurality (four) legs 95 are formed at equal intervals in the circumferential direction. As shown in FIG. 4, each leg portion 95 is in contact with the valve cylinder 84 of the first valve body 15 from above. The gap between the leg portions 95 adjacent to each other in the circumferential direction becomes a flow path of the contents from the communication hole 56 to the communication passage R.
The outer cylinder portion 93 is located inside the annular protrusion 54b in the radial direction. The lower end of the outer cylinder portion 93 is in contact with or in close contact with the connecting ring portion 55. A connecting portion 94 is connected to the upper end portion of the outer cylinder portion 93.

Next, the operation of the compact container 10B in the present embodiment will be described as being different from the first embodiment.

In the present embodiment, when the operating portion 73 is pressed and moves downward, the plate-shaped portion 91 of the guiding member 90 is also elastically displaced downward. At this time, an upward urging force acts on the operation portion 73 due to the plate-shaped portion 91 trying to be restored and displaced. That is, the guiding member 90 applies an upward urging force to the operation unit 73 that has moved downward. Then, the upward urging force of the guiding member 90 assists the elastically deformed operating portion 73 to be restored and displaced when the pushing down of the operating portion 73 is released. In this way, by stably returning the operation unit 73 to the position before pushing down by the upward urging force of the guiding member 90, the contents are stably sucked from the inner container 12 into the communication space S, and then the operation unit 73. It is possible to stabilize the discharge amount of the contents when the 73 is pushed down.

Further, the plate-shaped portion 91 faces the operation portion 73 in the vertical direction, and a groove 91a extending in the radial direction is formed on the upper surface of the plate-shaped portion 91. With this configuration, the flow path of the contents from the communication passage R to the discharge hole 14a can be secured by the groove 91a. In particular, when the plate-shaped portion 91 upwardly urges the operating portion 73 that has moved downward, even if the plate-shaped portion 91 and the operating portion 73 are in close contact with each other, the flow path of the contents can be secured. Therefore, the contents can be discharged more stably.

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

For example, in the first and second embodiments, the second valve body 14b is formed integrally with the operation unit 73, but the second valve body 14b may be a separate body from the operation unit 73.
Further, instead of the groove 81b in the first embodiment, or in addition to the groove 81b, a rib protruding downward from the lower surface of the plate-shaped portion 81 and extending in the radial direction may be provided. Alternatively, instead of the groove 91a in the second embodiment, or in addition to the groove 91a, a rib protruding upward from the upper surface of the plate-shaped portion 91 and extending in the radial direction may be provided. Even in these cases, the ribs can secure the flow path of the contents.

In addition, it is possible to replace the constituent elements in the above-described embodiment with well-known constituent elements as appropriate without departing from the spirit of the present invention, and the above-described embodiments and modifications may be appropriately combined.
For example, the first embodiment and the second embodiment may be combined to form radial grooves or ribs on both the upper surface and the lower surface of the plate-shaped portion 81 or the plate-shaped portion 91. Alternatively, the guiding member 80 of the first embodiment may be configured to urge the operating portion 73 that has moved downward.
