Although it is possible to absorb shocks by providing such a cushioning member, since the shock projections support the shocks, the shocks can be transmitted from the shock projections to the inner dish container. It cannot be prevented.

Therefore, it is conceivable to hold the medium dish container in a suspended state in the container body with a fixing frame made of a thermoplastic elastomer so that the impact can be absorbed as much as possible. However, the thermoplastic elastomer is flexible and absorbs the impact. Good, but flexible and non-shape-retaining. Therefore, if it is left as it is, it is difficult to handle when assembling the container, and it is not easy to attach it to the medium dish container. In this respect, the holding piece made of a soft elastic material of Japanese Utility Model Publication No. 61-35612 is also the same.

Even when it can be mounted on the inner dish container, it is not easy to assemble the inner dish container with such a flexible fixing frame made of elastomer into the container body.

The present invention has been made under the background as described above. It is made of a thermoplastic elastomer and has a sufficient shape-retaining property, so that it can be easily attached to a medium dish container or a container body. It is an object to provide a fixed inner plate fixing frame.

[0010]

The present invention adopts the following means in order to solve the above problems.

That is, the compact container of the present invention is a medium plate fixing frame 5 for holding the peripheral edge of the medium plate container 4 to be accommodated in the container body 1 of the compact container and fixing it to the container body 1, which is a ring frame. The base 6, the first and second fixing legs 7 and 8 provided on the lower surface of the frame base 6, and the frame base 6
The ring-shaped frame base 6 is made of synthetic resin and has at least one hole 9 penetrating from the lower surface to the upper surface.
The fixed leg 8 and the annular projection 13 are made of thermoplastic elastomer and are integrally molded through the hole 9, and the first fixed leg 7 is fitted inside the container body 1. The second fixed leg 8 is provided inside the frame base 6 apart from the first fixed leg 7, and the peripheral wall of the inner plate container 4 is fitted between the first fixed leg 7 and the second fixed leg 8. In the compact container, the bottom part of the inner dish container 4 is separated from the bottom part of the container body 1 and held in a suspended state when the inner dish container 4 is fixed to the container body 1. It is a plate fixing frame.
