When the inner pressure of the communication space 65 descends due to upward movement of the operation part 58, the second valve body 16 shuts down communication between the discharge hole 66 and the communication space 65, and the first valve body 15 communicates the communication hole 56 with the communication space 65. The lower surface of the inner lid 13 is formed with a communication path 101 which extends in the radial direction of the inner lid 13 and communicates an outer peripheral part inside the inner container 12 with the communication hole 56.SELECTED DRAWING: Figure 4

Description

  The present invention relates to a compact container.

  DESCRIPTION OF RELATED ART The cosmetics storage container provided with the inside plate container which accommodated cosmetics is known (for example, refer patent document 1). In the cosmetic container of Patent Document 1, the upper surface of the inner plate container is covered with a net.

JP 2003-93145 A

  In the conventional cosmetic container described above, the cosmetic covering the inner plate container is pressed with a puff or the like to exude the cosmetic through the mesh of the net and discharge the cosmetic to the outside. However, in this case, it is difficult to adjust the discharge amount of the cosmetic, and it is difficult to discharge the cosmetic by a desired amount.

  An object of this invention is to provide the compact container which adjustment of the discharge amount of the content is easy.

In order to solve the above-mentioned subject, the present invention proposes the following means.
The compact container according to the present invention contains the contents, and the inner container which can be reduced in volume as the content decreases, and the inside of the inner container are sealed and communicated with the inside of the inner container. A communication space is provided between the inner lid in which the hole is formed and the upper surface of the inner lid and in communication with the communication hole between the inner lid and the inner lid, and the content is communicated with the communication space. Switching the communication between the discharge hole and the communication space, and the switching of the first valve body switching the communication between the communication hole and the communication space, and the shutoff of the inner lid in which the discharge hole to be discharged is formed And a second valve body, wherein the inner lid defines the communication space and is formed so as to be elastically deformable, and includes an operation unit that increases or decreases the internal pressure of the communication space by elastic deformation, the operation unit Moves downward and the internal pressure of the communication space rises The first valve body interrupts the communication between the communication hole and the communication space, and the second valve body causes the discharge hole to communicate with the communication space, and the operation portion moves upward. When the internal pressure of the communication space drops, the second valve body interrupts the communication between the discharge hole and the communication space, and the first valve body cuts the communication hole and the communication space. A communication passage is formed on the lower surface of the inner lid so as to extend in the radial direction of the inner lid and to communicate between the outer peripheral portion in the inside of the inner container and the communication hole.

  According to this configuration, when the operation unit moves downward and raises the internal pressure of the communication space, the first valve body interrupts the communication between the communication hole and the communication space, and the second valve body is the discharge hole And communicate with the communication space. In addition, when the operating portion moves upward and lowers the internal pressure of the communication space, the second valve body interrupts the communication between the discharge hole and the communication space, and the first valve body communicates with the communication hole and the communication space Communicate. For this reason, the user depresses the operation unit or releases the depression to elastically deform the operation unit to increase or decrease the internal pressure of the communication space, thereby making the communication space negative pressure and causing the inner container to be inside. The content of the content can be flowed into the communication space, and the content can be filled in the communication space. In this state, when the operation unit is pushed down to raise the internal pressure of the communication space, the content can be discharged from the discharge hole by an amount corresponding to the increase of the internal pressure of the communication space.

In this manner, the contents can be stably sucked from the inner container into the communication space, and the discharge amount of the contents when the operation unit is subsequently depressed can be made to be a desired amount.
Therefore, adjustment of the discharge amount of the contents is easy.

  By the way, the inner container is configured to be capable of reducing and deforming as the content decreases. Therefore, the inner container is reduced in volume as the contents flow out to the communication space through the communication hole. For example, if the inner container is in close contact with the lower surface of the inner lid in the process of volume reduction deformation from the central portion to the outer peripheral side of the bottom of the inner container, communication is made with a portion located radially outward of the contact portion There is a risk that the communication with the hole is blocked, and the flow of contents toward the communication hole may be impeded.

  Therefore, in the configuration according to the present invention, the communication passage is formed on the lower surface of the inner lid, for communicating between the outer peripheral portion in the inner container and the communication hole. Therefore, even if the inner container is in close contact with the inner lid before the volume reduction deformation of the inner container propagates to the outer peripheral side in the process of reducing the volume of the inner container along with the use of the contents, the outer peripheral portion in the inner container Communication between the valve and the communication hole is secured through the communication passage. Thereby, it can be suppressed that the flow of the contents from the inner container to the discharge hole accompanying the operation of the operation unit is inhibited, and the contents of the inner container can be used up effectively.

In the compact container according to the present invention, the inner lid is provided with a valve seat portion which defines the communication hole and to which the first valve body can be attached and detached, and the lower surface of the inner lid is provided at the lower side. A protrusion is formed and extends radially to define the communication path together with the lower surface of the inner lid, and the lower surface of the valve seat is located above the lower end of the protrusion Good.
According to this configuration, it is possible to suppress the inner container from coming into close contact with the valve seat earlier than the projection. This prevents the communication between the communication hole and the communication path from being interrupted, and the contents can be used up effectively.

  According to the compact container of the present invention, it is easy to adjust the discharge amount of the contents.

The first valve body 15 allows the flow of fluid (content, the same applies hereinafter) from the accommodation space 45 of the inner container 12 to the communication space 65 and blocks the flow of fluid from the communication space 65 to the accommodation space 45. In the example of the present embodiment, a three-point valve is used as the first valve body 15. In addition, according to the property etc. of the contents accommodated in the inner container 12, for example, changing the shape of the three-point valve appropriately or adopting a check valve having a configuration different from the three-point valve as the first valve body 15 can do.

The second valve body 16 is a valve that switches the communication between the discharge hole 66 of the inner lid 14 and the communication space 65 and the blocking thereof. In the present embodiment, the second valve body 16 is provided on the inner lid 14. The second valve body 16 is integrally formed with the operation portion 58.
The second valve body 16 is formed by a portion including the opening peripheral portion of the discharge hole 66 in the operation portion 58. In the present embodiment, the second valve body 16 is formed in a portion of the operation portion 58 surrounded by the cylindrical restriction wall portion 81.

  The second valve body 16 is thinner than the other portions of the operation portion 58 and the thin portion 64. The plan view shape of the second valve body 16 is similar to the plan view shape of the second valve seat portion 67, and is larger than the plan view shape of the second valve seat portion 67 (see FIG. 1). As shown in FIG. 2, the second valve body 16 blocks the communication between the discharge hole 66 and the communication space 65 by being seated on the second valve seat portion 67. The second valve body 16 brings the discharge hole 66 into communication with the communication space 65 when the second valve body 16 is elastically deformed and separated from the second valve seat portion 67. The second valve body 16 is a check valve. The second valve body 16 permits the flow of fluid from the communication space 65 to the outside, and blocks the flow of fluid from the outside to the communication space 65.

  In the communication space 65, a biasing portion 91 is disposed between the upper member 47 of the inner lid 13 and the operation portion 58 of the inner lid 14. The biasing portion 91 is located on the container axis O. Specifically, the biasing portion 91 has a deformation portion 92 and a fitting portion 93. The biasing portion 91 may be integrally formed on the lower surface of the operation portion 58.

  The deformation portion 92 is formed in a dome shape protruding upward. The deformation portion 92 covers the valve main body 85 of the first valve body 15 from the upper side of the valve main body 85. The top of the deformation portion 92 approaches or abuts on the lower surface of the operation portion 58 from the lower side of the operation portion 58. The deformation portion 92 is configured to be elastically deformable in the vertical direction Z in accordance with the displacement of the operation portion 58 in the vertical direction Z. That is, the deformation portion 92 elastically deforms when the operation portion 58 is pressed down, and biases a portion of the operation portion 58 overlapping the first valve body 15 as viewed from the vertical direction Z upward. The biasing unit 91 may bias the operation unit 58 in a state where at least the operation unit 58 is moved downward.

  The deformation portion 92 is formed with a through hole 95 penetrating the deformation portion 92 in the vertical direction Z. A plurality of through holes 95 are formed in the deformation portion 92 at intervals in the circumferential direction. The through hole 95 communicates the internal space of the biasing portion 91 with the external space.

  The fitting portion 93 is continuously provided at the lower end portion of the deformation portion 92 over the entire circumference. The fitting portion 93 is formed thicker than the deformation portion 92. The fitting portion 93 is fitted in the mounting cylindrical portion 52.

In the present embodiment, the inner container 12, the inner lid 13 and the inner lid 14 constitute a refill container 17. The refill container 17 is detachably provided to the outer shell 11. This allows the user to replace the refill container 17 with a new refill container 17 filled with contents after the contents in the inner container 12 are used up.
When removing the refill container 17 from the shell 11, the user releases the engagement between the engagement claw of the engagement plate portion of the bottom member 21 and the circumferential groove of the mounting ring 57.

  Here, as shown in FIG. 2 and FIG. 3, a projection 100 is formed on the lower surface of the inner cover disc portion 48 of the lower member 46 described above. The projection 100 projects downward from the lower surface of the inner lid disc portion 48 and extends in the radial direction. The protrusion 100 is formed such that the circumferential width is uniform throughout the radial direction. In the present embodiment, a plurality of projections 100 having the same shape and size are arranged radially with respect to the container axis O. In the illustrated example, four projections 100 are arranged at equal intervals in the circumferential direction. However, the number of the projections 100 can be appropriately changed to, for example, twelve.

  The radial inner end of each protrusion 100 extends beyond the boundary between the inner lid disc portion 48 and the mounting portion 51 and reaches the mounting portion 51. The radially outer end of each protrusion 100 is located radially inward with respect to the boundary between the inner lid disc portion 48 and the inner cylindrical portion 49. However, the length in the radial direction of each protrusion 100 can be changed as appropriate. For example, each protrusion 100 may be formed over the inner lid disc portion 48 and the mounting portion 51, or may be formed only on any of the inner negative disc portion 48 and the mounting portion 51.

  In each protrusion 100, the amount of protrusion (height) in the vertical direction Z from the lower surface of the inner lid disc portion 48 is set to be equal. The height in the vertical direction Z of each protrusion 100 is uniformly set over the entire radial direction. In the present embodiment, the lower end of each protrusion 100 is located below the lower end edge of the cylindrical portion 53 a of the first valve seat portion 53. The lower end of each projection 100 may be located at the lowermost end of the inner lid 13.

  A portion defined by the lower surface of the inner lid disc portion 48 and each projection 100 is a series connecting the outer peripheral portion and the inner peripheral portion (communication hole 56) of the accommodation space 45 (inside of the inner container 12). The passage 101 is configured. In the present embodiment, the communication passage 101 is radially disposed about the container axis O. The width of each communication passage 101 in the circumferential direction is gradually narrowed from the radially outer side toward the radially inner side.

Next, the discharge method of the content of the compact container 10 of this embodiment is demonstrated.
When the compact container 10 is in an unused state, the contents are accommodated only in the accommodation space 45, and the communication space 65 is filled with air, for example.
First, the user operates the push piece 37 to open the lid 22 of the shell 11. The operation portion 58 is pressed from above and elastically deformed so as to be depressed downward. When the operation portion 58 is elastically deformed so as to be depressed downward, the volume of the communication space 65 is reduced, so the internal pressure of the communication space 65 is increased. That is, by moving at least a part of the operation unit 58 downward, the internal pressure of the communication space 65 is increased. Then, the second valve body 16 is elastically expanded and deformed upward by the internal pressure of the communication space 65 and separated from the second valve seat portion 67, and the closed state of the discharge hole 66 is released. A portion of the air is discharged from the discharge holes 66 to the outside. Thereafter, the second valve body 16 is restored and deformed to be seated on the second valve seat portion 67, and the discharge hole 66 is closed. At this time, the first valve body 15 blocks the movement of fluid from the communication space 65 to the accommodation space 45, so the communication hole 56 is closed by the first valve body 15, and the air in the communication space 65 is a communication hole. The flow from 56 to the accommodation space 45 is suppressed. Thus, when the operating portion 58 moves downward and the internal pressure of the communication space 65 rises, the first valve body 15 shuts off the communication between the communication hole 56 and the communication space 65, and the second valve body 16. Communicates the discharge hole 66 with the communication space 65.

  Next, the user releases the pressing force applied to the operation unit 58, and restores the elastically deformed operation unit 58 to the original state. At this time, the biasing unit 91 biases the operation unit 58 upward to urge restoration and deformation. Further, the elastic plate 82 assists the restoration and deformation of the operation unit 58. As a result, the volume of the communication space 65 increases and the pressure in the communication space 65 becomes negative. That is, when the portion of the operation unit 58 moved downward is moved upward to the original position, the internal pressure of the communication space 65 is lowered. At this time, since the discharge hole 66 is closed by the second valve body 16, entry of air into the communication space 65 from the outside is suppressed. Therefore, the contents in the housing space 45 are sucked into the communication space 65 through the communication hole 56. Since the first valve body 15 allows the flow of fluid from the accommodation space 45 to the communication space 65, the first valve body 15 is in a state where the communication hole 56 and the communication space 65 are in communication. Not disturb the flow of As a result, the contents flow into the communication space 65. Thus, when the operating portion 58 moves upward and the internal pressure of the communication space 65 drops, the second valve body 16 shuts off the communication between the discharge hole 66 and the communication space 65 and the first valve body 15. Communicates the communication hole 56 with the communication space 65.

  The user can discharge the air of the communication space 65 to the outside and fill the communication space 65 with contents by performing the elastic deformation and the restoration of the operation unit 58 a plurality of times. Here, the inner container 12 has flexibility, and the volume decreases as the contents flow out to the communication space 65 through the communication holes 56 (the volume is reduced), so the contents decrease. When the internal pressure of the storage space 45 is reduced, the inner container 12 is shrunk and the volume of the storage space 45 is reduced. As a result, even if the contents flow into the communication space 65 and the total amount of contents in the housing space 45 is reduced, the contents can be stably sent from the housing space 45 to the communication space 65. It is.

  When the operation portion 58 is elastically deformed in a state where the contents are filled in the communication space 65, the internal pressure of the communication space 65 is increased. As a result, the second valve body 16 bulges and deforms upward, and the clogging of the discharge hole 66 is released. Therefore, the contents pushed out from the communication space 65 are discharged from the discharge hole 66 to the outside. In this way, the user can discharge the contents. The contents are discharged from the discharge hole 66 to the inside of the raised portion 62 in the upper surface of the inner lid 14. Therefore, the contents can be prevented from spilling from the upper surface of the inner lid 14. The user wipes the upper surface of the inner lid 14 with a puff P or the like to adhere the contents to the puff P or the like for use.

  By the way, as shown in FIG. 4, when the volume of the inner container 12 is reduced with the use of contents, for example, in the bottom of the inner container 12, the volume reduction deformation is propagated from the central portion in the radial direction to the outer peripheral side Go. That is, in the bottom portion of the inner container 12, after the central portion in the radial direction first dents upward, the outer circumferential side gradually dents upward. When the bottom of the inner container 12 is in close contact with the lower surface of the inner lid disc portion 48 in the process of volume reduction deformation from the central portion to the outer peripheral side, the bottom of the inner container 12 is radially outward The communication between the located portion and the communication hole 56 is interrupted, and the flow of the contents toward the communication hole 56 may be hindered.

  On the other hand, in the present embodiment, the inner container 12 is in close contact with the projection 100 before the inner container 12 is in close contact with the lower surface of the inner lid disc portion 48 in the process of volume reduction deformation of the inner container 12. As a result, since the volume reduction deformation of the inner container 12 relative to the inner lid 13 is restricted, it is possible to suppress the inner container 12 from being in close contact with the lower surface of the inner lid disc portion 48. That is, in the housing space 45, the communication between the communication hole 56 and the region radially outside the close contact portion S of the inner container 12 and the protrusion 100 is maintained through the communication passage 101.

  Then, as described above, when the communication space 65 becomes negative pressure by the operation of the operation unit 58, the contents located in the region radially outward with respect to the close contact portion S in the inner container 12 radially in the communication passage 101 It flows inwards. Thereafter, the contents flow into the communication space 65 through the communication hole 56. On the other hand, as shown in FIG. 5, with the outflow of the contents from the inner container 12 to the communication space 65, the inner container 12 undergoes volume reduction deformation toward the outer peripheral side again.

  As described above, according to the compact container 10 of the present embodiment, when the operating portion 58 moves downward and raises the internal pressure of the communication space 65, the first valve body 15 is in communication with the communication hole 56. And the second valve body 16 brings the discharge hole 66 into communication with the communication space 65. Further, when the operating portion 58 moves upward and lowers the internal pressure of the communication space 65, the second valve body 16 shuts off the communication between the discharge hole 66 and the communication space 65, and the first valve body 15 The communication hole 56 and the communication space 65 are communicated with each other. For this reason, the user depresses the operation portion 58 or releases the depression to elastically deform the operation portion 58 to increase or decrease the internal pressure of the communication space 65 to make the inside of the communication space 65 a negative pressure. The contents in the inner container 12 can flow into the communication space 65, and the contents can be filled in the communication space 65. In this state, when the operating portion 58 is pushed down to raise the internal pressure of the communication space 65, the content can be discharged from the discharge hole 66 by an amount corresponding to the increase of the internal pressure of the communication space 65.

Thus, the contents can be stably sucked from the inner container 12 into the communication space 65, and the discharge amount of the contents when the operation unit 58 is subsequently depressed can be made to be a desired amount.
Therefore, in the compact container 10 of the present embodiment, adjustment of the discharge amount of the contents is easy.

In particular, in the present embodiment, the lower surface of the inner cover disc portion 48 is formed with the communication passage 101 for communicating between the outer peripheral portion in the inner container 12 and the communication hole 56.
According to this configuration, even if the inner container 12 is in close contact with the inner lid disc portion 48 before the volume reduction deformation of the inner container 12 propagates to the outer peripheral side, the outer peripheral portion and the communication hole 56 inside the inner container 12 And the communication between them are secured through the communication passage 101. Thereby, it can be suppressed that the flow of the contents from the inner container 12 to the communication hole 56 accompanying the operation of the operation unit 58 is inhibited, and the contents of the inner container 12 can be used up effectively.

In the present embodiment, the protrusion 100 defining the communication passage 101 is formed on the lower surface of the inner lid disc portion 48, and the lower end of the protrusion 100 is positioned below the lower end edge of the cylindrical portion 53a of the first valve seat 53. It was set up.
According to this configuration, the inner container 12 can be prevented from coming into close contact with the cylindrical portion 53 a earlier than the protrusion 100. This prevents the communication between the communication hole 56 and the communication passage 101 from being interrupted, and the contents can be effectively used up.

  Moreover, in the present embodiment, since the communication passage 101 is formed by the protrusion 100 formed on the lower surface of the inner lid disc portion 48, the inner container 12 adheres to the protrusion 100 and then follows the outer surface of the protrusion 100. Reduce volume. Thereby, it can be visually recognized through the confirmation hole 31 that the outer shape of the protrusion 100 is raised in the inner container 12. Therefore, the operator can determine the remaining amount of the content in the inner container 12 by the degree of the protrusion 100 floating on the inner container 12. That is, since the protrusion 100 can be used as an indicator which shows the residual amount of the content in the inner container 12, the compact container 10 excellent in usability can be provided.

Second Embodiment
Next, a second embodiment of the present invention will be described. In the following description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.
In the compact container 10 shown in FIG. 6, a plurality of (for example, four each) first protrusions 200 and second protrusions 201 are alternately arranged in the circumferential direction on the lower surface of the inner lid disc portion 48. The radial length and the circumferential width of each of the protrusions 200 and 201 are equal to each other. In the present embodiment, the portion defined by the adjacent projections 200 and 201 and the lower surface of the inner lid disc portion 48 constitutes the communication passage 101.

  The height of the first protrusion 200 in the vertical direction Z is higher than that of the second protrusion 201. That is, the lower end of the first protrusion 200 is located below the lower end of the second protrusion 201. The height of the first protrusion 200 is set to be the same as that of the protrusion 100 of the first embodiment. In each of the protrusions 200 and 201, the height in the vertical direction Z is uniformly set over the entire radial direction.

  According to the present embodiment, in the process of volume reduction deformation of the inner container 12 due to the use of the contents, the inner container 12 is first in close contact with the four first protrusions 200. Thus, the appearance of the outer shape of the first protrusion 200 in the inner container 12 can be visually recognized through the confirmation hole 31. Thereafter, the inner container 12 is in close contact with the four second protrusions 201 by the volume reduction deformation of the inner container 12. Thereby, it can be visually recognized through the confirmation hole 31 that the outer shape of the second protrusion 201 in addition to the first protrusion 200 is raised in the inner container 12. That is, since the number of protrusions which float up from the inner container 12 differs according to the remaining amount of the content in the inner container 12, the remaining amount of the content in the inner container 12 can be judged in stages. Thereby, the usability can be improved. In the present embodiment, the case where two types of protrusions 200 and 201 having different heights are provided has been described. However, the present invention is not limited to this configuration, and three or more types of protrusions having different heights may be provided.

Third Embodiment
Next, a third embodiment of the present invention will be described.
In the compact container 10 shown in FIG. 7, the confirmation window 301 is fitted in the confirmation hole 31. The confirmation window 301 is preferably formed of a light transmissive material (a transparent material or a translucent material). In addition, when the whole bottom member 21 is formed with the material which has light transmittance, it is not necessary to provide the confirmation hole 31 and the confirmation window 301. FIG.

  As shown in FIG. 8, on the lower surface of the inner lid disc portion 48, a display portion 302 is formed in a portion located between the adjacent protrusions 100 (in the communication passage 101). The display portion 302 protrudes downward from the lower surface of the inner lid disc portion 48. The height of the display portion 302 is lower than the height of the protrusion 100. That is, the lower end of the protrusion 100 is located below the lower end of the display unit 302. In the present embodiment, the plan view shape of the display unit 302 is, for example, a heart shape. However, the shape in plan view of the display unit 302 can be changed as appropriate, such as circular or rectangular.

  According to the present embodiment, in the process of volume reduction and deformation of the inner container 12 due to the use of the contents, the inner container 12 first adheres to the four projections 100. Thus, the appearance of the outer shape of the protrusion 100 on the inner container 12 can be visually recognized through the confirmation window 301. Thereafter, the inner container 12 is in close contact with the four display portions 302 by further reducing the volume of the inner container 12. Thereby, it can be visually recognized through the confirmation window 301 that the outer shape of the display unit 302 is raised on the inner container 12 in addition to the protrusion 100. That is, since the shape of the inner lid disc portion 48 which floats up from the inner container 12 differs in accordance with the remaining amount of the content in the inner container 12, the amount of the remaining content in the inner container 12 is judged in stages. Can. Thereby, the usability can be improved. In the present embodiment, the case where one type of display unit 302 having different heights is provided with respect to the protrusion 100 has been described, but not limited to this configuration, two or more types of display units having different heights may be provided. It is also good.
