Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hermetically sealed structure of a compact container capable of maintaining a moisturized state for a long period of time for a foundation having a high water content called an emulsion type, for example.

[0002]

[Prior art]

 Conventionally, an airtight cosmetic container is described in JP-A-10-192044 as a compact container for storing a foundation having a high water content. This container is a container in which the pressing force of the packing by the inner lid is equalized as a whole to enhance the airtight performance in order to increase the sealing force of the inner lid formed as a double container.

[0003]

[Problems to be solved by the invention]

 However, the conventional airtight cosmetic container has a configuration in which the upper end surface of the packing and the contact surface of the inner lid are press-bonded even if the pressing force of the packing is entirely uniform, so that the space between these surfaces When the foundation adheres, a small gap is formed in the adhered portion, and as a result, the internal foundation dries from the small gap. In particular, in a foundation having a high water content called an emulsion type, since this water content is a characteristic, a compact container that holds this water for as long as possible is desired. However, it is difficult to maintain such a water-containing state for a long period of time in a conventional closed container, and there has been an inconvenience that the characteristics of a foundation having a high water content cannot be maintained.

[0004] Further, if the sealing force is to be further increased in the conventional hermetic cosmetic container, the pressing force for pressing the packing is increased. Then, there is a possibility that the opening / closing operation may be inconvenient, for example, the pressure may hinder the opening / closing operation.

Therefore, the present invention has been devised to solve the above-mentioned problems, and has as its object to provide a sealed structure of a compact container which has extremely high moisturizing power and can be easily opened and closed.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a first means of the present invention is to provide an elastic packing 20 buried in a peripheral edge of a container body 10 or a container lid 30 for storing a high moisture content foundation. In the compact structure of a compact container comprising a container lid 30 or a sealing projection 31 provided on the peripheral edge of the container body 10 corresponding to the packing 10, a groove 21 is provided on the surface of the packing 20 where the sealing projection 31 contacts. The sealing projection is inserted and fixed in the groove 21 when the container lid 30 is covered.

The packing 20 of the second means is housed in a housing recess 11 provided around the container body 10 or the container lid 30, and an opening of the housing recess 11 is provided with an upper end of the packing 20. And a pair of fixing projections 12 are formed so as to protrude.

Further, the packing 20 of the third means includes an introduction portion 23 inserted between the fixing protrusions 12 of the storage recess 11, and a crimping portion extending upward from the introduction portion 23 and formed in a bifurcated cross section. And a groove 21 for elastically deforming the crimping portion 22 when the crimping portion 22 is housed in the housing recess 11 to form the groove 21 for crimping the sealing projection 31. This is a means to solve the problem.

[0009]

[Embodiment of the invention]

 As an embodiment of the present invention, a storage recess 11 formed on the peripheral edge of the container body 10, a packing 20 stored in the storage recess 11, and a seal provided on a container lid 30 which is pressed into the groove 21 of the packing 20. An example with the protrusion 31 will be described (see FIG. 1).

The storage recess 11 of the container main body 10 is provided around the container main body 10 of the container main body 10, and a pair of fixing projections 12 that lock the upper end of the packing 20 into the opening of the storage recess 11. (See FIG. 2). The fixing protrusion 12 may be formed on the entire circumference of the storage recess 11, or may be selectively provided at a key portion of the storage recess 11 as shown in FIG.

The packing 20 has a ring shape formed of a rubber material or another elastic material, and has a groove 21 for press-fitting the sealing projection 31 on a surface where the tip of the sealing projection 31 contacts. The illustrated packing 20 is provided with a crimping section 22 having a bifurcated cross section which is elastically deformed to form the groove 21 when inserted between the fixing projections 12 of the storage recess 11. In addition, below the crimping portion 22, an introduction portion 23 for introducing the crimping portion 22 into the storage recess 11 from between the fixing protrusions 12 of the storage recess 11 is provided. The packing 20 usually has a substantially Y-shaped cross section. When the packing 20 is stored in the storage recess 11, the storage recess 11 forcibly presses the crimping portion 22 to seal the packing 20. A groove 21 having an optimum width for crimping the protrusion 31 is formed in the crimp portion 22 (see FIG. 3). In the packing 20 stored in the storage recess 11, the crimping portion 22 tries to expand by its own elastic force, and furthermore, a pair of fixing protrusions 12 formed to project from the opening of the storage recess 11, and the upper end of the crimping portion 22 is formed. Since the portion is locked, when the sealing projection 31 pressed into the groove 21 is extracted, the packing 20 is prevented from coming out together with the sealing projection 31 (see FIG. 2). In addition, when the sealing portion 31 is press-fitted into the groove portion 21 when the sealing protrusion 31 is pressed into the groove portion 21, the pressing force is absorbed by the elastic force of the introducing portion 23. Can be absorbed by the packing 20.

Although the sealing projection 31 of the container lid 30 is provided integrally with the container lid 30 in the illustrated example, the sealing projection 31 may be provided separately.

In the embodiment, for convenience of explanation, the packing 20 is housed in the container body 10 and the sealing projection 31 is formed on the container lid 30, but the packing 20 is housed in the container lid 30. However, since the same sealing effect can be obtained even if the sealing projection 31 is provided on the container body 10, the present invention is not limited to the above embodiment.

[0014]

[Effect of the invention]

 The present invention has achieved the original object by being configured as described above. That is, according to the first aspect, even if the foundation adheres to the packing 20, the sealing projection 31 is forcibly inserted into the crimping portion 22 of the packing 20 to seal the packing 20, so that the moisture retention is extremely high. It has become possible to maintain the characteristics of a foundation with a high water content for a long time.

Further, the fixing projection 12 according to the second aspect prevents the packing 20 from falling out of the storage recess 11 and facilitates opening and closing operations. Further, since the packing 20 is stored in the storage recess 11, even if a slight error occurs in the dimensional accuracy of the container body 10 or the container lid 30, the packing 20 absorbs the error and does not reduce the sealing force. I'm done.

Further, the crimping portion 22 and the introducing portion 23 according to the third aspect facilitate the mounting of the packing 20 of the present invention and can securely crimp the sealing projection 31.

As described above, according to the present invention, it is possible to maintain the characteristics of a foundation having a very high moisturizing power and a high water content for a long period of time, and to be able to easily perform opening and closing operations. Various advantageous effects are obtained.
