Description

[0001]
[Industrial application fields]
The present invention relates to an airtight compact container as a portable cosmetic container that stores cosmetics such as powder and stores the cosmetics in an airtight state in a closed state.
[0002]
[Prior art]
There are various types of airtight compact containers that are portable containers for holding cosmetics in an airtight manner, but a lid is provided at the opening edge of the cosmetic storage recess of the container main body for storing the cosmetics of the compact containers. Compared to the structure in which the ring-shaped sealing functional body assembled to the container is in close contact, the sealing functional body that covers the entire opening of the cosmetic storage recess of the container main body is assembled to the lid, and this sealing functional body is attached to the container main body. It is well known that the structure having the close contact with the opening edge of the cosmetic housing recess exhibits a high and stable sealing performance.
[0003]
As prior arts constructed by assembling a lid with a sealing functional body covering the entire opening of the cosmetic storage recess of the container body, Japanese Utility Model Publication No. 5-27124, Japanese Utility Model Publication No. 6-2585, and further As disclosed in Japanese Patent Application Laid-Open No. 7-10659, a sealing portion that tightly elastically contacts the opening edge of the cosmetic storage recess of the container main body with respect to the portion of the sealing function body that is assembled to the lid body. It can be easily elastically displaced by pressure contact with the side.
[0004]
In the above-described prior art, the seal portion of the sealing function body can be easily elastically displaced by the pressure contact with the container body side, so that the local portion accompanying deformation fatigue of the seal portion can be obtained. It is possible to prevent the occurrence of permanent deformation and elastic deterioration as much as possible, thereby exhibiting the advantage that a stable sealing function can be exhibited over a long period of time.
[0005]
[Problems to be solved by the invention]
However, in the above prior art, due to a slight displacement from the state where the seal part of the sealing function body is in close contact with the container body side to the closed state where the lid body is locked and fixed to the container body, The internal pressure of the sealed cosmetic storage space increases, and the increased internal pressure elastically displaces the sealed portion of the sealing functional body that is easily elastically deformed, and the elastic displacement is displaced in a direction that lowers the sealing state. Therefore, there is a problem that the sealing performance is lowered.
[0006]
In addition, as described above, since the sealing portion of the sealing functional body is constantly subjected to a force that is elastically displaced in the direction of lowering the sealing state, the sealing performance exhibited by an external impact when carrying is large. Therefore, there is a problem that high sealing performance cannot be stably exhibited.
[0007]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and it is a technical problem to prevent deterioration of the sealing performance due to an increase in the internal pressure of the cosmetic storage space after achieving the seal. The purpose of the present invention is to exhibit a high and stable sealing property of the cosmetic storage space by the sealing function body.
[0008]

The middle dish body is tightly fitted to the opening of the attached middle dish body, and sealing of the middle dish body by the seal body is achieved.
[0014]
The sealing of the inner tray body by the seal body is achieved by tightly fitting the tightly fitting cylindrical piece of the sealing body into the opening of the intermediate dish body. The internal pressure of the sealed inner tray increases as the close fitting progresses to the part.
[0015]
When the internal pressure of the intermediate dish starts to rise, the central deformed portion of the seal body that is thin and easily elastically deforms is elastically deformed in a direction that reverses its curved posture by the internal pressure of the intermediate dish, and the internal pressure of the intermediate dish increases. Reduce the degree.
[0016]
The elastic deformation of the central deformation part of the seal body that reduces the increase in internal pressure of the intermediate dish body is due to the fact that the central deformation part itself is thin and the joint part between the central deformation part of the seal body and the assembled peripheral end. The presence / absence of the formed expansion / contraction groove is achieved very smoothly, and exhibits a sufficient suppression effect of an increase in the internal pressure of the intermediate dish.
[0017]
That is, when the central deforming portion starts to deform in the bulging direction that reverses the bending posture due to the internal pressure of the inner plate body, the expansion / contraction groove deforms in a direction to decrease the groove width, and the central deforming portion moves in the bulging direction. The deformation is easily performed, and thereby, the deformation of the central deformation portion in the bulging direction is smoothly achieved, thereby suppressing the increase in the internal pressure of the inner tray body.

According to the third aspect of the present invention, the assembly of the sealing body is formed by the pressing cylinder piece using the assembling force of the lid body in the closed posture state, which is in a state of being immovably engaged with the container body. Since the attached peripheral end portion is pressed against the opening edge of the middle dish body, the tight fitting of the tightly fitting cylinder piece of the sealing body with respect to the opening portion of the middle dish body is firmly achieved and maintained thereby. The inner plate seal is more powerful.
[0021]
In the invention according to claim 4, since the receiving circumferential groove of the seal body and the pressing cylinder piece of the lid body are fitted, the assembled peripheral end portion of the sealing body is displaced in a delirium state when the pressing cylinder piece is pressed. Thus, the seal reinforcing action by the pressing cylinder piece is effectively exhibited.
[0022]
