2. Description of the Related Art As an airtight container with an inner lid of this kind, there is a cosmetic compact disclosed in, for example, Utility Model Registration No. 2523785. This cosmetic compact includes a container main body provided with a cosmetic storage section, an inner lid covering the upper side of the storage section, and an outer lid further covering the inner lid, and the outer lid is screwed to the container main body. By screwing in, the inner lid is pressed by the outer lid, and the tightness of the storage portion by the inner lid is enhanced. The inner lid is hinged to the container body via a hinge so as to be openable and closable.

[0003]

However, in the above-mentioned cosmetic compact, the hinge for hingedly attaching the inner lid to the container main body has a notch at the upper end of the peripheral portion of the container main body, and a hinge pin extends across both sides of the notch. On the other hand, a holding portion is protruded outward from the peripheral edge of the inner lid, and the holding portion is fitted and supported on a hinge pin, and the inner lid is formed around the hinge pin. It is turned. At this time, the holding portion is positioned by the hinge pin, and even when the screwing force of the outer lid acts and the inner lid is pressed against the storage portion of the container body, the inner lid is centered on the hinge pin, Only the side of the inner lid opposite to the side where the hinge is arranged is pushed down. For this reason, even if the inner lid is provided with a skirt valve on the peripheral edge portion that closes the storage portion, there is a problem that the pressed state is biased and the sealing performance is reduced.

Accordingly, the present invention has been made in view of such a conventional problem, and when the screwing force of the outer lid acts,
It is an object of the present invention to provide an airtight container in which the inner lid is evenly sunk in the entire circumference to enhance the tightness of the inner lid.

It is characterized by being engaged so as to be relatively movable in the sealing direction.

According to this structure, in order to hermetically close the container body, the inner lid is first closed around the hinge and closed, and then the outer lid is covered so as to cover the inner lid. The lid is screwed into the container body and screwed in, and the screwing force of the outer lid is applied to the inner lid. At this time, the distal end portion of the extension piece provided with the hinge is engaged with the container body so as to be relatively movable in the sealing direction of the inner lid due to the screwing force of the outer lid, so that when the screwing force is applied, The inner lid can be pushed down as a whole together with the hinge, and the hermeticity of the inner lid is improved.

The hinge is formed by a bendable portion obtained by thinning a part of the extension piece, and the extension piece is movably inserted into an outer peripheral portion of the container body. A passage is formed.

According to this structure, the hinge is formed by a bent portion formed on the extension piece, and the bent portion is formed by thinning a part of the extension piece. Can be. Further, since the extension piece is inserted into the passage inside the outer peripheral portion of the container body, the extension piece does not protrude from the outer periphery of the container body. Therefore, the outer lid can be screwed to the container body without the extension piece and the hinge affecting the screwed portion of the outer lid at all. For this reason, the outer diameter of the outer lid can be reduced, and the airtight container can be formed compact as a whole.
