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 above-described cosmetic container, by pressing the net covering the inner plate container with a puff or the like, the cosmetic is exuded through the mesh of the net and discharged 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 view of the above-mentioned problem.

In order to solve the above-mentioned subject, the present invention proposes the following means.
In the compact container according to the present invention, the content is contained, and the transparent inner container which is reduced in volume as the content decreases, the inside of the inner container is sealed, and the communication hole communicating with the inside of the inner container is formed. A discharge space which is provided above the inner lid and which is in communication with the communication hole between the inner lid and the inner lid, and which discharges the contents by communicating with the communication space A second valve for switching the communication between the discharge hole and the communication space, and a first valve for switching the communication between the communication hole and the communication space, and the communication between the communication hole and the communication space And a display unit disposed in the inner container and in contact with the volume-reduced inner container, the inner lid defining the communication space and being elastically deformable and elastically deformable And an operation unit for increasing or decreasing the internal pressure of the communication space, When the operation part 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 discharges the discharge hole And the communication space, and when the operation unit moves upward and the internal pressure of the communication space drops, the second valve body blocks the communication between the discharge hole and the communication space, and The first valve body communicates the communication hole with the communication space.

  According to this compact container, when the operating portion 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 discharges A hole and communication space are made to connect. 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.

  Moreover, the display part is provided in the inside container. When the inner container is reduced in volume and comes in contact with the display unit, the user visually recognizes the display unit through the transparent inner container, and the change in the shape of the inner container caused by the inner container coming in contact with the display unit By confirming a change in color or the like, the user can recognize that the inner container is in contact with the display unit. As a result, the user can recognize the remaining amount of the contents in the inner container and, for example, can grasp the time of replacement.

  The display unit may be movably supported toward the communication hole along the axial direction of the communication hole in a state where the display portion is positioned on the axial line of the communication hole.

If, in the process of reducing the volume of the inner container, a portion of the inner container located on the axis of the communication hole (hereinafter referred to as “on-axis portion”) is preferentially reduced in volume relative to the other portions, There is a possibility that the axial portion may close the communication hole. In this case, even if the content remains in the inner container, the content can not pass through the communication hole, and the content remains in the inner container.
According to this compact container, the display portion is supported so as to be movable toward the communication hole side along the axial direction of the communication hole in a state where the display portion is positioned on the axial line of the communication hole. Therefore, even if the axial portion of the inner container is subjected to volume reduction deformation preferentially to the other portions as described above, the display unit resists the volume reduction deformation. As a result, it is possible to reduce and deform the other portion preferentially in comparison with the on-axis portion. As a result, it becomes possible to suppress that the contents in the inner container remain, and the contents can be used efficiently.

  The display device may further include an outer shell that houses the inner container, and the outer shell may be provided with a window that allows the display to be viewed through the inner container.

  In this case, the window is provided in the shell. Therefore, it is possible to visually recognize that the volume-reduced inner container is in contact with the display part from the outside of the outer shell through the window while maintaining the state in which the outer shell protects the inner container.

  The window portion may be formed of a concave spherical lens member recessed toward the inside of the outer shell.

  In this case, the window is formed by the lens member. Therefore, it is possible to visually recognize the inner container and the display unit in an enlarged state by visually observing whether or not the volume-reduced inner container is in contact with the display unit from the outside of the outer shell through the lens member. it can.

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

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.

  The biasing unit 101 biases the operation unit 58, which has moved downward, upward. The biasing portion 101 is elastically deformable.

  The dome wall portion 103 has a dome shape that is convex upward. The central portion (top portion) of the dome wall portion 103 abuts on the lower surface of the operation portion 58 from below. In the dome wall portion 103, a through hole 104 which penetrates the dome wall portion 103 in the vertical direction Z is formed. A plurality of through holes 104 are formed in the dome wall portion 103 at intervals in the circumferential direction. The through hole 104 communicates the internal space of the biasing portion 101 with the external space. The contents flow through the through hole 104.

  When the operating portion 58 is pushed down, the biasing portion 101 elastically deforms. At this time, the biasing unit 101 biases the operation unit 58 upward by the restoring deformation force.

  The display unit 111 is disposed in the inner container 12. The reduced inner container 12 abuts on the display unit 111. In the unopened state (unused state, initial state) before the contents are discharged from the compact container 10, the display unit 111 is configured such that the inner member 12 and the upper member 47 of the inner lid 13 of the inner lid 13 It is disposed in a state of being separated from the lower surface of the The display unit 111 is movably supported toward the communication hole 56 side along the vertical direction Z (axial direction of the communication hole 56) in a state of being positioned on the container axis O (axial line of the communication hole 56) ing.

The display unit 111 includes a main body unit 112 and a support unit 113.

In the present embodiment, the convex portion 118 forms a character string "END" in the plan view. A second groove 119 communicating the inside and the outside of the “D” in the plan view is provided in a portion forming the “D” of the convex portion 118.

  As shown in FIG. 3, the support portion 113 movably supports the main body portion 112 upward in a state where the main body portion 112 is positioned on the container axis O. The support portion 113 connects the main body portion 112 and the inner lid 13. The support portion 113 is elastically deformable. The support portion 113 separates the main body portion 112 from the inner surface of the inner container 12 and the lower surface of the upper member 47 of the inner lid 13 in the inner container 12 in the natural length state (state not elastically deformed). It is placed in the The support portion 113 is elastically deformed when the main body portion 112 moves upward.

  As shown in FIG. 4, the support portion 113 includes a plurality of elastic connection pieces 120. The plurality of elastic connection pieces 120 are arranged at intervals in the circumferential direction. Each elastic connection piece 120 includes a main body piece 121, a first connection piece 122, and a second connection piece 123. The main body piece 121 extends in the circumferential direction. The first connection piece 122 connects one end portion in the circumferential direction of the main body piece 121 and the main body portion 112. The second connection piece 123 connects the other end of the main body piece 121 in the circumferential direction to the inner lid 13.

As shown in FIG. 2, 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.

  The outer shell 11 is provided with a window 11 a that allows the display 111 to be viewed through the inner container 12. The window portion 11 a is provided on the bottom member 21 of the outer shell 11. The window portion 11 a is disposed coaxially with the container axis O. The window portion 11a is formed by the lens member 11b. The lens member 11 b has a concave spherical shape that is recessed upward (inside the outer shell 11). In the present embodiment, an opening 11 c coaxial with the container axis O is formed in the bottom member 21, and the lens member 11 b is attached to the opening 11 c. The lens member 11b is colorless and completely transparent. The lens member 11 b is located at a height position higher than the lower surface of the outer shell 11. The lens member 11 b is larger in diameter than the display unit 111 (main body unit 112), and the entire display unit 111 can be viewed through the lens member 11 b.

  In the illustrated example, the fixing ring 11d is provided on the lens member 11b. The fixing ring 11d protrudes outward in the radial direction from the outer peripheral edge of the lens member 11b. The lens member 11 b is fixed to the outer shell 11 via the fixing ring 11 d by fitting the lower surface of the fixing ring 11 d to the opening peripheral edge of the opening 11 c in the bottom member 21 from above.

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 101 biases the operation unit 58 upward to urge restoration. 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, when the contents flow out from the accommodation space 45 in the inner container 12 to the communication space 65 in the process of performing the elastic deformation and restoration of the operation unit 58 a plurality of times, first, on the container axis O of the inner container 12 ( The portion located on the axis of the communication hole 56 (hereinafter referred to as "on-axis portion 12a") is preferentially reduced in volume relative to other portions. At this time, the on-axis portion 12a is deformed upward, and a portion of the inner container 12 located radially outward with respect to the on-axis portion 12a (hereinafter referred to as "peripheral portion 12b") is an axis. The amount of deformation is smaller than that of the upper portion 12a, or maintained in a non-deformed state.

  When the on-axis portion 12a abuts on the display portion 111, the further deformation of the on-axis portion 12a is suppressed by the elastic force of the display portion 111 (support portion 113). Thereafter, volume reduction deformation is performed until the peripheral portion 12b of the inner container 12 abuts the lower surface of the inner lid 13 (lower member 46). At this time, when the peripheral portion 12b of the inner container 12 abuts on the lower surface of the outer peripheral portion 48a of the inner lid 13, the housing space 45 and the peripheral peripheral space 45a radially outside the outer peripheral portion 48a (see FIG. 5) The two spaces 45a and 45b are divided into a central space 45b (see FIG. 5) located radially inward of the outer peripheral portion 48a, but both of the spaces 45a and 45b pass through the gaps between the protruding ridges 48c adjacent in the circumferential direction. It is communicated. Therefore, even if contents remain in the peripheral space 45a, the contents can be discharged from the compact container 10 through the gap and the central space 45b.

  When the contents are discharged a plurality of times, the on-axis portion 12a of the inner container 12 gradually rises with the display unit 111 against the elastic force of the display unit 111, as shown in FIG. 5 and FIG. The portion 111 abuts on the lower surface of the inner lid 13 (upper member 47). Thereafter, when the content is to be further discharged, the internal container 12 is further reduced in volume, and the content in the recess 116 is pushed out of the recess 116 by the inner container 12 through the first groove portion 117 as shown in FIG. Be Thereby, the inner container 12 (the on-axis portion 12a) is in pressure contact with the display portion 111, and the character string ("END") of the marker portion 114 is three-dimensionally lifted. The content pushed out from the concave portion 116 is discharged to the outside of the display portion 111 through the first groove portion 117, and then flows into the communication groove 53d through the gap between the display portion 111 and the support portion 113. It circulates toward 53 d of communicating holes.

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.

  In addition, a display unit 111 is provided in the inner container 12. When the inner container 12 is reduced in volume and comes in contact with the display unit 111, the user visually recognizes the display unit 111 through the transparent inner container 12, and the content is attributed to the inner container 12 coming in contact with the display unit 111 By confirming the change in the shape, the color, and the like of the container 12, the user can recognize that the inner container 12 is in contact with the display unit 111. As a result, the user can recognize the remaining amount of the contents in the inner container 12 and, for example, can grasp the time of replacement.

Further, the outer shell 11 is provided with a window portion 11 a. Therefore, visually observing that the volume-reduced inner container 12 abuts the display portion 111 from the outside of the outer shell 11 through the window portion 11 a while maintaining the outer shell 11 protecting the inner container 12. Can.
Furthermore, the window part 11a is formed of the lens member 11b. Therefore, the inner container 12 and the display unit 111 are enlarged by visually observing whether or not the reduced inner container 12 abuts on the display unit 111 from the outside of the outer shell 11 through the lens member 11 b. It can be viewed in the state.

By the way, if the axial portion 12a of the inner container 12 is reduced in volume preferentially in comparison with the peripheral portion 12b (the other portions) in the process of reducing the volume of the inner container 12, the axial portion 12a will There is a risk of blocking. In this case, even if the content remains in the inner container 12, the content can not pass through the communication hole 56, and the content remains in the inner container 12.
According to the compact container 10, the display unit 111 is supported so as to be movable upward while being positioned on the container axis O. Therefore, even if the axial portion 12a of the inner container 12 attempts to reduce the volume preferentially in comparison with the peripheral portion 12b as described above, the display portion 111 resists the volume reduction. Thus, the peripheral portion 12b can be reduced in volume preferentially in comparison with the on-axis portion 12a. As a result, it becomes possible to suppress that the contents in the inner container 12 remain, and the contents can be used efficiently.

Further, a biasing unit 101 is provided which biases the operation unit 58 moved downward to the upper side. Therefore, when the depression of the operation unit 58 is released, the biasing unit 101 stably returns the operation unit 58 to the original position before the depression. That is, the biasing unit 101 assists the resiliently deformed operation unit 58 to be restored and deformed. As a result, 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 next 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 addition, since the operation portion 58 is stably returned to the position before the depression by the biasing portion 101, the operability of the operation portion 58 is good. As a result, by forming the operation portion 58 of an elastically deformable soft material such as an elastomer, for example, even when the sealability by the second valve body 16 is secured, it is possible to have good restorability.

Further, since the operation unit 58 defines the communication space 65, for example, the operation unit 58 can be formed large according to the size of the communication space 65, and the user operates the discharge of the contents. It can expand the possible range.
Further, in the present embodiment, since the biasing unit 101 biases the portion of the operation unit 58 overlapping the first valve body 15 when viewed in the vertical direction Z, the following effects can be obtained.
That is, in this case, the operation unit 58, the biasing unit 101, and the first valve body 15 can be arranged in the vertical direction Z. Since the operation unit 58 and the first valve body 15 can be arranged at a close position, the fluctuation (positive pressure, negative pressure) of the internal pressure of the communication space 65 when the operation unit 58 is operated acts on the first valve body 15 It can be made easy. Therefore, the operation of the first valve body 15 is stabilized.
In addition, a portion of the operation portion 58 that is positioned immediately above the first valve body 15 that is particularly difficult to restore and deform can be reliably returned to the original position by the biasing portion 101.

Moreover, in the present embodiment, since the biasing portion 101 is disposed between the inner lid 13 and the middle lid 14, the biasing portion 101 can be easily provided. Further, the urging unit 101 acts to push up the operation unit 58 from the inside of the communication space 65, and the restorability of the operation unit 58 is favorably maintained.
Further, in the present embodiment, since the biasing portion 101 is dome-shaped, the resilience after elastic deformation is good.
Further, in the present embodiment, the biasing portion 101 can be formed of an optimum material for biasing the operation portion 58 upward. That is, since the biasing portion 101 is separate from the first valve body 15 and the second valve body 16, the degree of freedom in selecting the material of the biasing portion 101 can be increased. Also, the formability of the biasing portion 101 is good.

  Further, an annular thin portion 64 is formed in the operation portion 58. Therefore, a portion of the operation portion 58 located radially inward of the thin portion 64 can be easily elastically deformed from the thin portion 64 as a starting point. As a result, the internal pressure of the communication space 65 can be greatly increased and decreased, and the adjustment of the discharge amount of the contents can be made easier.

  The inner lid 14 also has a mounting ring 57. Therefore, the mounting ring 57 can be appropriately formed to be rigid while securing the operability based on the elastic deformation of the operation portion 58, and the mounting property of the inner lid 14 to the inner lid 13 can be secured by the mounting ring 57. As a result, both the operability of the operation unit 58 and the mountability of the inner lid 14 can be secured.

  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, as described below, for example.

In the above-mentioned embodiment, although the character of mark part 114 is formed of convex part 118, it may be formed of a crevice. In this case, a relief groove may be further provided for releasing the contents remaining in the recess to the outer peripheral edge portion of the display unit from the recess.
In addition, the indicator portion 114 may not be a letter. For example, the marker part 114 may form a symbol, a code, a figure or the like different from the characters. In the first embodiment, when the user visually recognizes the marking portion 114, it can be recognized that the remaining amount of the content is exhausted based on the meaning content ("END") indicated by the marking portion 114. However, the semantic content indicated by the marker 114 is not limited to this.

In addition, the color of the content and the color of the display unit 111 may be adjusted as appropriate.
For example, the color of the content and the color of the display unit 111 are the same, and the characters (signs, signs, symbols such as symbols) of the sign unit 114 are formed by the convex portions 118 as in the first embodiment. In this case, the user may be made to recognize that there is no remaining amount as in the first embodiment, as in the first embodiment. In this case, even if the inner container 12 abuts on the convex portion 118 due to volume reduction deformation of the inner container 12, it is difficult to recognize the character string, but the contents disappear and the inner container 12 is in pressure contact with the lower surface of the display unit 111 Since the character string can be visually recognized by raising the character string (convex part 118) from the inner container 12, the user can recognize that there is no remaining amount.
For example, the color of the content and the color of the display unit 111 are different, and the characters (signs, signs, symbols such as symbols) of the sign unit 114 are formed by the convex portions 118 as in the first embodiment. In this case, the meaning content of the character string indicated by the marker 114 may be different from the first embodiment, and may allow the user to recognize that the remaining amount is small. In this case, when the inner container 12 abuts on the convex portion 118 due to the volume reduction deformation of the inner container 12, the character string (convex portion 118) becomes visible, and the user recognizes that the remaining amount is small. It can be done. On the other hand, when the content is lost and the inner container 12 is in pressure contact with the display unit 111, the character string floats up from the inner container 12 so that the user can recognize that there is no remaining amount.
For example, when the color of the content and the color of the display unit 111 are different, and the characters (signs, symbols, signs such as figures, etc.) of the sign unit 114 are formed by the recess unlike the first embodiment. As in the first embodiment, the user may be made to recognize that there is no remaining amount of the meaning contents of the character string indicated by the marker portion 114. In this case, even if the inner container 12 approaches and abuts on the lower surface of the display unit 111 due to the volume reduction deformation of the inner container 12, it is difficult to recognize the character string, but the contents disappear and the inner container 12 becomes the display unit 111. By leaving the content in the recess while discharging the content from the lower surface of the display unit 111 when pressing against the lower surface, the character string (recess) becomes visible, so there is no remaining amount Can be made to recognize.
For example, the color of the content and the color of the display unit 111 are the same, and the characters (signs, symbols, signs such as figures, etc.) of the sign unit 114 are formed by the recess unlike the first embodiment. In this case, the meaning content of the character string indicated by the marker portion 114 may be made possible to allow the user to recognize that there is no remaining amount as in the first embodiment. In this case, even if the inner container 12 approaches and abuts on the lower surface of the display unit 111 due to the volume reduction deformation of the inner container 12, it is difficult to recognize the character string, but the contents disappear and the inner container 12 becomes the display unit 111. By discharging the contents through the escape groove not only from the lower surface of the display unit 111 but also from within the recess when pressing against the lower surface, the character string (recess) can be recessed for three-dimensional visual recognition. The user can be made aware that there is no remaining amount.

Furthermore, the marking part 114 may not be necessary. For example, as in a display section 131 according to a modification shown in FIG. 8, the display section 131 may be formed of an elastically deformable strip member 132. The strip member 132 has a spiral shape in a plan view as viewed from the up and down direction Z. One end of the strip member 132 is located radially outward of the other end. One end of the strip member 132 is connected to the locking portion 51 a of the inner lid 13. The strip member 132 extends downward from one end to the other end.
In this case, when the contents in the inner container 12 decrease and the volume of the inner container 12 is reduced, first, the other end of the strip member 132 (the central portion of the spiral shape formed by the strip member 132) Abut. Thereafter, when the inner container 12 is further reduced in volume, the strip member 132 is gradually compressed and deformed in the vertical direction Z, and the contact area between the inner container 12 and the strip member 132 is increased. At this time, the belt-like member 132 gradually abuts on the inner container 12 from the other end to the one end (from the central portion of the spiral shape to the outer peripheral portion). In the strip member 132, the whole including the connecting portion with the locking portion 51 abuts the inner container 12, and when the entire strip member 132 becomes visible through the inner container 12, the user can It can be recognized that the amount has run out.

In the embodiment described above, the biasing unit 101 biases a portion of the operation unit 58 that overlaps the first valve body 15 as viewed in the vertical direction Z. The biasing unit may bias a portion of the operation unit 58 which does not overlap the first valve body 15 as viewed in the vertical direction Z.
The biasing portion may not be disposed between the inner lid 13 and the inner lid 14.

Although not particularly shown, the communication space 65 includes a main communication space in which the communication hole 56 opens and a sub communication space in communication with the main communication space, and operates at least a part of the wall defining the sub communication space. It may be a department. In this case, the biasing portion may be provided in the sub communication space, and the biasing portion may bias the operation portion upward. Furthermore, in this case, the sub communication space may be formed in an annular shape coaxial with the container axis, and the operation unit may be formed in an annular shape that defines the sub communication space.
The operating portion may be in the form of a button or a dome that bulges upward.

The biasing portion may be integrally formed on the inner lid 13.
In this case, since the biasing portion is integrally formed on the inner lid 13, the number of parts can be reduced and the structure of the compact container can be simplified. In addition, since the movement of the biasing portion in the container is suppressed, the function of the biasing portion is well maintained.
There may not be a biasing unit.

  The elastic plate 82 may be integrally formed with the upper member 47 of the inner lid 13 instead of being integrally formed with the operation portion 58. The shape of the elastic plate 82 is not limited to the rectangular plate shape, and may be appropriately changed to other plate shapes, shapes other than the plate shape, and the like.

The planar view shape of the operation unit 58 is not particularly limited, and may be an elliptical shape, a triangular shape, a quadrangular shape, or a polygonal shape having five or more sides.
The operation portion 58 may not be integrally formed with the upper member 47, may be formed separately from the upper member 47, and may be attached to the upper member 47.
Further, the shape of the inner container 12 is not particularly limited, and may be, for example, an elliptical cylinder or an angular cylinder.
Further, the inner container 12, the inner lid 13 and the inner lid 14 may not constitute the refill container 17. That is, when the contents are used up, the inner container 12 may not be replaced.

The mounting ring 57 may not be provided. Instead of including the mounting ring 57, the elastically deformable operating portion 58 (elastically deformable portion) may be mounted on the inner lid 13 by being formed in, for example, a top cylindrical shape.
The discharge hole 66 may not be formed in the operation portion 58. For example, the mounting ring 57 may be provided with a flange projecting radially inward and defining the communication space 65, and the discharge hole 66 may be provided in the flange.
Only one discharge hole 66 may be formed.
The second valve 16 may not be formed by the operating portion 58, and the second valve 16 may be formed by a member different from the operating portion 58.
