Description

  The present invention relates to an airtight compact having a double structure in which an inner tray for filling contents is disposed in a container body having a lid, and the inner tray is kept airtight by the inner lid.

  Such compacts are mainly used to store contents containing volatile components, and examples of such contents include cosmetics such as foundations and eye shadows.

In addition, as a conventional structure for improving airtightness, a container with a lid for filling the contents and a container body with a lid for storing the dish with the lid are separately provided. When closing the lid (outer lid), the structure is used to increase the airtightness by pressing the lid (inner lid) of the middle dish against the opening of the middle dish with this outer lid (for example, Patent Documents) 1).
Japanese Patent No. 3778308

  In the conventional airtight compact, for the purpose of improving the usability, the push piece incorporated on the container body side pushes up the outer lid to release the engagement with the container body, and pushes up the inner lid. A second release portion for releasing the engagement with the inner dish is provided, and the outer lid and the inner lid are simultaneously opened.

  However, in the compact structure of this type, the mechanism for opening the outer lid and the mechanism for opening the inner lid, which should originally exist separately, are configured integrally. After opening and taking out the contents and closing only the inner lid, when opening the inner lid again to take out the contents, there is no choice but to push the push piece, and there is room for improvement in terms of usability .

The problem to be solved by the present invention is to use a push piece that pushes up the lid and releases the engagement with the container body, and operates the release portion provided integrally with the middle plate to push up the middle lid and The configuration is to release the engagement of
The purpose is to be able to open the inner lid at the same time by reliably operating the release part formed on the lid and the inner tray, and a new airtightness that can open only the inner lid by a separate and independent operation. To provide a compact.

  The hermetic compact according to the present invention includes an inner tray filled with contents, a container main body in which the inner tray is disposed, and is held by the container main body so as to be opened and closed via a pivot, and is engaged with the container main body in a closed state. A lid that can be opened and closed via a pivot and maintains the inner tray in an airtight state, and a push piece that is slidably held in the container body and that disengages the lid by pushing. The inner lid includes an operation piece that is swingably or rotatably connected to an edge facing the pivot of the inner lid, and the operation lid is suspended toward the bottom of the container body. The push piece includes a pressing portion that performs a pushing operation, an extension portion that is connected to the pressing portion and extends toward the operation piece, and the extension portion and the thin portion. Point that can be swung The container body includes a working surface that pushes up so that the tip of the protruding piece slides and opens the inner lid by swinging or rotating upward of the operation piece, and the push piece is pushed in It has a slope which pushes up so that the above-mentioned tip part of a push piece may slide and rock the above-mentioned operation piece to the upper part.
