Description

  The present invention relates to a compact container.

  2. Description of the Related Art A cosmetic container that includes an inner dish container that stores cosmetics is known (see, for example, Patent Document 1). In the cosmetic container of Patent Document 1, the upper surface of the middle dish container is covered with a net.

JP 2003-93145 A

  In the above-described conventional cosmetic container, the net covering the inner dish container is pressed with a puff or the like, so that the cosmetic is oozed through the mesh of the net and discharged to the outside. However, in this case, the discharge amount is likely to change due to the force applied when the net is pressed, and it is not easy to discharge the cosmetic by a desired amount.

  The present invention has been made in consideration of such circumstances, and an object thereof is to provide a compact container capable of discharging a desired amount of contents with higher accuracy.

  In order to solve the above-described problem, a compact container according to one embodiment of the present invention is formed with an inner container in which contents are stored, and a communication hole that seals the inside of the inner container and communicates with the inner container. A discharge space provided between the inner cover and the inner cover, defining a communication space communicating with the communication hole between the inner cover and discharging the contents in communication with the communication space; An inner lid in which a hole is formed; a first valve body for switching communication between the communication hole and the communication space; and a second valve for switching communication between the discharge hole and the communication space; A body, and the inner lid includes an operation part that defines the communication space, and the operation part is provided with at least two pressing parts having different plane areas, and the two pressing parts are By being elastically deformable and elastically deforming, When the internal pressure of the communication space is increased or decreased and at least one of the two pressing portions moves downward to increase the internal pressure of the communication space, the first valve body communicates with the communication hole and the communication space. And the second valve body allows the discharge hole and the communication space to communicate with each other, and when at least one of the two pressing portions moves upward to lower the internal pressure of the communication space, The second valve body blocks communication between the discharge hole and the communication space, and the first valve body allows communication between the communication hole and the communication space.

According to the above aspect, when the pressing portion moves downward to increase the internal pressure of the communication space, the first valve body blocks communication between the communication hole and the communication space, and the second valve body is a discharge hole. And communication space. In addition, when the pressing portion moves upward to lower the internal pressure of the communication space, the second valve body blocks communication between the discharge hole and the communication space, and the first valve body communicates with the communication hole and the communication space. To communicate. For this reason, the user can increase or decrease the internal pressure of the communication space by depressing the pressing portion or releasing the pressing and elastically deforming the pressing portion, thereby making the communication space negative pressure. The contents can be made to flow into the communication space, and the contents can be filled into the communication space. In this state, if the pressing portion is pushed down to increase 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.
The operation portion is provided with at least two pressing portions having different plane areas. These pressing portions are different in the amount of elastic deformation when they are pressed down, so that the discharge amount of the contents is also different. Therefore, the user can select the discharge amount of the contents depending on which pressing portion is pressed, and can discharge a desired amount of the contents with higher accuracy. Further, for example, after discharging the contents, it is possible to easily perform an operation of additionally discharging a smaller amount of contents.
Also, for example, when the contents are cosmetics, when applying cosmetics to the entire face, press the pressing part with a large flat area, and when applying to a small area such as the eyes, press the pressing part with a small flat area. It is also possible to use it by pressing it.

  Here, when the plane areas of the two pressing portions are A1 and A2, respectively, A2 ≦ 1/2 × A1 may be satisfied.

  In this case, the difference between the flat areas of the two pressing parts is sufficiently large, so that the difference in the amount of elastic deformation when the two pressing parts are pressed increases. Thereby, the difference of the discharge amount by which pressing part is pressed becomes clear, and operability can be improved.

  Further, the two pressing parts may have a shape bulging upward from the operation part.

In this case, when the pressing portion is pressed, the pressing portion is elastically deformed so as to be reversed. In the case of the reverse deformation as described above, the deformation amount is stabilized as compared with the case where the reverse deformation is not performed. Since the discharge amount of the contents depends on the deformation amount of the pressing portion, it becomes possible to discharge a fixed amount of the contents with higher accuracy.
Furthermore, since the pressing portion bulges upward from the operation portion, the position of the pressing portion can be easily recognized, and the force required to push down the pressing portion and discharge the contents can be reduced. Therefore, the operability when the pressing portion is pressed can be further improved.

  The operation portion may be formed to be elastically deformable, and may be elastically deformed to increase or decrease the internal pressure of the communication space.

  In this case, it is possible to discharge a large amount of contents at a time by pushing down the entire operation unit to cause elastic deformation. Alternatively, it is possible to discharge an arbitrary amount of contents depending on how much the operation unit is depressed. Therefore, depending on whether only the pressing portion is pressed or whether the entire operation portion is pressed, the range of selection of the discharge amount by the user is widened, and the operability can be further improved.

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

As shown in FIGS. 3A and 3B, the upper surfaces of the pressing portions 100 </ b> A and 100 </ b> B bulge upward from the upper surface of the operation unit 58. The upper and lower surfaces of the pressing portions 100A and 100B are formed in a curved surface shape that is convex upward.

The plane area of the first pressing part 100A is larger than the plane area of the second pressing part 100B.
When the plane area of the first pressing part 100A is A1 and the plane area of the second pressing part 100B is A2, A2 is equal to or less than ½ of A1, that is, A2 ≦ 1/2 × A1. preferable.
A2 is more preferably 1/3 or less of A1, that is, A2 ≦ 1/3 × A1. In the present embodiment, A2 is 1/4 or less of A1, that is, A2 ≦ 1/4 × A1. Thus, by satisfying A2 ≦ 1/4 × A1, the difference in the discharge amount depending on which one of the first pressing portion 100A and the second pressing portion 100B is pressed becomes more remarkable.
100 A of 1st press parts are arrange | positioned in the part located in the operation part 58 on the opposite side to the side which contains the container axis | shaft O and the 2nd valve body 16 has shifted | deviated with respect to the container axis | shaft O. . In the illustrated example, the pressing portions 100 </ b> A and 100 </ b> B are formed in a portion located behind the second valve body 16 in the operation portion 58.

  The positions of the top surface of the top portion of the first pressing portion 100A located at the uppermost position and the upper end portion of the raised portion 62 of the inner lid 14 are equal to each other in the vertical direction Z. The top part of the first pressing part 100A is located behind the container axis O. The top part of the first pressing part 100 </ b> A is located at the center part in the left-right direction Y of the operation part 58. The first pressing portion 100A is opposed to the communication hole 56 and the first valve body 15 in the up-down direction Z.

The pressing portions 100A and 100B are formed so as to be elastically deformable, and increase or decrease the internal pressure of the communication space 65 by elastically deforming. As a material of the pressing portions 100A and 100B, for example, a soft material such as elastomer, nitrile rubber, butyl rubber, silicon rubber, soft polyethylene, or urethane can be used. In consideration of chemical resistance with respect to the contents, for example, elastically deformable and relatively soft polypropylene (PP), thin polyethylene terephthalate (PET), or the like may be used as the material of the pressing portions 100A and 100B.
In the present embodiment, the pressing parts 100 </ b> A and 100 </ b> B are integrally formed of the same material as the operation part 58. Note that, for example, the operating portion 58 formed of a hard resin may be used as an insert product, and the pressing portions 100A and 100B may be formed of the resin softer than the operating portion 58 by insert molding.

  Next, a method for discharging the contents of the compact container 10 of this embodiment will be described. In the following description, the operation of each unit when the first pressing unit 100A is pressed will be described using the operation unit 58, the first pressing unit 100A, and the second pressing unit 100B as representatives. However, when the operation unit 58 or the second pressing unit 100B is pressed instead of the first pressing unit 100A, the same effects as described below can be obtained.

When the compact container 10 is not in use, the contents are accommodated only in the accommodating space 45, and the communication space 65 is filled with, for example, air.
First, the user operates the push piece 37 to open the lid member 22 of the outer shell body 11. Next, the first pressing portion 100A is pressed and elastically deformed so as to be recessed downward. When the first pressing portion 100A is elastically deformed so as to be depressed downward, the volume of the communication space 65 is reduced, and the internal pressure of the communication space 65 increases. That is, the internal pressure of the communication space 65 is increased by moving the first pressing portion 100A downward. Then, the second valve body 16 is elastically bulged 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 part of the air is discharged from the discharge hole 66 to the outside.

  Thereafter, the second valve body 16 is restored and deformed and is seated on the second valve seat portion 67 to close the discharge hole 66. At this time, the first valve body 15 blocks the movement of the 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 communicated with the communication hole 65. The flow from 56 to the accommodation space 45 is suppressed. Thus, when the first pressing portion 100A moves downward and the internal pressure of the communication space 65 rises, the first valve body 15 blocks the communication between the communication hole 56 and the communication space 65, and the second valve The body 16 makes the discharge hole 66 and the communication space 65 communicate with each other.

  Next, the user releases the pressing force applied to the first pressing portion 100A, and restores these elastically deformed portions to the original state. Thereby, the volume of the communication space 65 increases, and the inside of the communication space 65 becomes negative pressure. That is, the first pressure portion 100A moved downward is moved upward toward the original position, so that the internal pressure of the communication space 65 decreases. At this time, since the discharge hole 66 is closed by the second valve body 16, the entry of air into the communication space 65 from the outside is suppressed. Therefore, the contents in the accommodation 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 with each other. Does not obstruct the flow. As a result, the contents flow into the communication space 65. Thus, when the first pressing portion 100A moves upward and the internal pressure of the communication space 65 decreases, the second valve body 16 blocks the communication between the discharge hole 66 and the communication space 65, and the first valve The body 15 makes the communication hole 56 and the communication space 65 communicate with each other.

  The user can discharge the air in the communication space 65 to the outside and fill the content in the communication space 65 by performing the elastic deformation and restoration of the first pressing portion 100A described above a plurality of times. it can. Here, the inner container 12 has flexibility, and the volume is reduced (the volume is deformed) as the contents flow out to the communication space 65 through the communication hole 56. When the internal pressure of the storage space 45 is reduced, the inner container 12 is reduced in size and the volume of the storage space 45 is reduced. Thereby, even when the content flows into the communication space 65 and the total amount of the content in the accommodation space 45 is reduced, the content can be stably sent from the accommodation space 45 to the communication space 65. It is.

  When the communication space 65 is filled with contents, if the first pressing portion 100A is elastically deformed, the internal pressure of the communication space 65 increases. Thereby, the 2nd valve body 16 bulges and deforms upwards, and obstruction | occlusion of the discharge hole 66 is cancelled | released. Accordingly, the content pushed out from the communication space 65 is 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 on the upper surface of the inner lid 14. Therefore, it can suppress that the contents spill from the upper surface of the inner lid 14. The user uses the contents attached to the puff P by wiping the upper surface of the inner lid 14 with the puff P or the like.

  As described above, according to the compact container 10 of the present embodiment, the user pushes down the first pressing portion 100A and releases the pushing down to elastically deform these portions, thereby causing the communication space 65 to be formed. By increasing or decreasing the internal pressure, the inside of the communication space 65 can be set to a negative pressure so that the content in the inner container 12 can flow into the communication space 65 and the content can be filled into the communication space 65. In this state, when the first pressing portion 100A is pushed down to increase the internal pressure of the communication space 65, the contents can be discharged from the discharge holes 66 by an amount corresponding to the increase of the internal pressure of the communication space 65.

  As described above, the content is stably sucked from the inner container 12 into the communication space 65, and the discharge amount of the content when the first pressing portion 100A is pressed down next is set to a desired amount. it can. The operation portion 58 is provided with at least two pressing portions 100A and 100B having different plane areas. Since these pressing parts 100A and 100B have different elastic deformation amounts when pressed, the discharge amounts of the contents are also different. Therefore, the user can select the discharge amount of the contents depending on which one of the first pressing portion 100A and the second pressing portion 100B is pressed, and can discharge a desired amount of the contents with higher accuracy. it can. Further, for example, after discharging the contents, it is possible to easily perform an operation of additionally discharging a smaller amount of contents.

  For example, when the contents are cosmetics, when the cosmetic is applied to the entire face, the first pressing portion 100A having a large flat area is pressed, and when the cosmetic is applied to a small area such as the eyes, the flat area is small. It is possible to selectively use the second pressing unit 100B.

  Further, when A2 ≦ 1/2 × A1, the difference in the flat area of the pressing portions 100A and 100B is sufficiently large, so that the difference in elastic deformation when the pressing portions 100A and 100B are pressed is reduced. growing. Thereby, the difference of the discharge amount by which one of the 1st press part 100A and the 2nd press part 100B is pressed down becomes clear, and operativity can be improved.

Further, since the pressing portions 100A and 100B have a shape bulging upward from the operation portion 58, the pressed pressing portions 100A and 100B are elastically deformed so as to be reversed. In the case of the reverse deformation as described above, the deformation amount is stabilized as compared with the case where the reverse deformation is not performed. Since the discharge amount of the contents depends on the deformation amount of the pressing portions 100A and 100B, it is possible to discharge a fixed amount of the contents with higher accuracy.
Furthermore, the pressing parts 100A and 100B bulge upward from the operation part 58, so that the positions of the pressing parts 100A and 100B can be easily seen, and the pressing parts 100A and 100B are pressed down to discharge the contents. The force can be reduced. Therefore, the operability when pressing the pressing portions 100A and 100B can be further improved.

  In addition, since the pressing portions 100A and 100B are formed in a curved surface protruding upward, it is possible to reliably reduce the force required to push down the pressing portions 100A and 100B and discharge the contents. Become. Furthermore, for example, when the pressing portions 100A and 100B are pressed down while stroking the upper surface of the operation portion 58 with a finger, the upper surfaces of the pressing portions 100A and 100B can be smoothly slid without being caught by the finger.

  In the present embodiment, the operation portion 58 is also formed so as to be elastically deformable, and is configured to increase or decrease the internal pressure of the communication space 65 by elastic deformation. And it becomes possible to discharge a lot of contents at once by pushing down the operation part 58 entirely and making it elastically deform. Alternatively, it is possible to discharge an arbitrary amount of contents depending on how much the operation unit 58 is pushed down. Therefore, depending on whether only one of the first pressing unit 100A and the second pressing unit 100B is pressed or the entire operation unit 58 is pressed, the user can select a discharge amount and the operability is further improved. Can be improved. It is also possible to perform an operation of simultaneously pressing the first pressing part 100A and the second pressing part 100B, and discharge the amount of contents corresponding to the total elastic deformation amount of the pressing parts 100A, 100B.

  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 above-described embodiment, the upper surfaces of the pressing portions 100A and 100B bulge from the operation portion 58, but the upper surfaces of the pressing portions 100A and 100B and the upper surface of the operation portion 58 may be in the same position in the vertical direction. . In this case, for example, by forming a groove along the contour of the pressing portions 100A and 100B in the operation portion 58, the pressing portions 100A and 100B are configured to move up and down with respect to the operation portion 58 starting from the groove. Can do. Further, the upper and lower surfaces of the pressing portions 100A and 100B may be flat.

In the above-described embodiment, the entire operation unit 58 is formed to be elastically deformable. However, only the pressing units 100A and 100B of the operation unit 58 may be formed to be elastically deformable. In this case, since the deformation of the operation unit 58 when the pressing units 100A and 100B are pressed is suppressed, the contents can be discharged more stably and stably. When the operation portion 58 is not formed so as to be elastically deformable, the operation portion 58 formed of a hard resin is used as an insert product, and the pressing portions 100A and 100B are formed by insert molding with a softer resin than the operation portion 58. It is preferable to do.
Further, the pressing parts 100 </ b> A and 100 </ b> B may be formed thinner than other parts of the operation part 58.

  In addition, the constituent elements in the above-described embodiment can be appropriately replaced with known constituent elements without departing from the gist of the present invention, and the above-described embodiments and modifications may be appropriately combined.
