Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight compact container which is required to be airtight.

[0002]

2. Description of the Related Art Some cosmetics contain a volatile component. Containers such as compact containers for storing cosmetics containing volatile components of this type and replacement cosmetic containers have an airtight structure so that the volatile components are not volatilized. That is,
A packing made of an elastic material such as an elastomer is brought into pressure contact with the rim of the inner plate containing the volatile component-containing cosmetic.

[0003]

However, many of the above-mentioned volatile components increase in volatility due to temperature rise,
In some cases, the internal pressure in the container rises more than at room temperature, and this internal pressure overcomes the pressure contact force between the rim of the inner plate and the packing, and the airtightness of the compact container may be impaired.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to provide an airtight compact container which does not lose airtightness even if the temperature rises. .

[0005]

The present invention adopts the following means in order to solve the above problems. <Summary of the present invention> The gist of the present invention is that the container body is attached with an inner plate containing cosmetics, and the inside of the lid that closes the container body is airtight at the rim of the inner plate. In an airtight compact container provided with a packing that is pressed against the inner plate, the inner plate is attached so as to be movable in a direction approaching the packing of the lid, and a predetermined temperature is provided between the container body and the inner plate. A pressing body that deforms when the temperature becomes the above is interposed, and the intermediate plate can be pushed in a direction approaching the packing of the lid by the deformation of the pressing body when the temperature becomes equal to or higher than the predetermined temperature. It is an airtight compact container.

The points of the present invention will be briefly described below. As for the installation position of the pressing body, any position can be used as long as the pressing body can move the inner plate in a direction approaching the packing when the pressing body is deformed at a predetermined temperature or higher. I don't mind.

For example, a pressing body may be installed between the bottom portion of the container body and the bottom portion of the inner tray, or the pressing body may be placed between the rim portion of the inner tray and the supporting portion of the container body that supports it. May be installed.

With regard to the shape of the pressing body, any shape may be used as long as it has a function of pushing the inner plate in the direction approaching the packing when the pressing body is deformed at a temperature higher than a predetermined temperature. I don't mind.

For example, it may have a disc shape, an annular plate shape, a cylindrical shape, or a coil shape.

The material of the pressing body may be resin (so-called shape memory resin) or metal (so-called shape memory alloy).
But it is okay.

Various means such as a hinge means, a screw means, and a fitting means can be adopted as the means for connecting the container body and the lid.

<Applicability of the Present Invention> The airtight compact container according to the present invention includes a container for storing a replacement inner dish (so-called refill).

[0013]

[Action]

<Operation of the present invention> The pressing body maintains the shape at the time of setting until it reaches a predetermined temperature. At this time, the packing of the lid body is pressed against the rim of the inner plate to seal the inner plate. Until the predetermined temperature is reached, the volatilization amount of the volatile components in the cosmetic is small and the internal pressure rise in the inner plate is small, so that the airtight state of the inner plate can be sufficiently maintained even if the pressing body is not deformed. it can.

When the ambient temperature rises, the volatilization amount of the volatile components in the cosmetic increases, and as a result, the internal pressure in the inner plate also rises, but when the predetermined temperature is reached, the pressing body deforms to cover the inner plate. Push in the direction of approaching the body packing. This allows
The pressure contact force of the inner edge of the inner plate with respect to the packing is larger than that before the deformation of the pressing body, and the airtight state of the inner plate is maintained even if the internal pressure in the inner plate is increased.
