Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable hermetic cosmetic container containing cosmetics.

[0002]

2. Description of the Related Art In general, a cosmetic container called a compact for carrying cosmetics is used. This cosmetic container accommodates cosmetics in a container body and opens and closes freely at the rear end of the container body. The upper part of the container body is entirely covered with a lid to be hinged. The general structure is such that the closed state of the lid is maintained by a hook mechanism provided between the front ends of the container body and the lid.

As a cosmetic container of this type, there is a container in which a lid is formed in a double structure with an outer lid and an inner lid, as disclosed in Japanese Utility Model Laid-Open No. 58-3003. That is,
The outer lid is adapted to entirely close the container body, while the inner lid is adapted to close an inner plate containing cosmetics contained in the container body. The inner lid is rotatably hinged to the inner plate, seals the periphery of the opening of the inner plate via packing when the inner lid is closed, and when the outer lid of the container body is at the closed position, The inner lid is pressed by the outer lid to increase the tightness of the inner plate.

[0004]

In such a conventional cosmetic container, however, the inner plate containing the cosmetic is sealed with an inner lid hinged to the inner plate. The lid is adapted to be pivoted about a hinge pin to which it is hinged. For this reason, when closing the periphery of the opening of the inner plate with the inner lid through the packing, the pressing force differs between the side closer to the hinge and the side farther from the hinge due to the principle of leverage. Then, when trying to obtain the required pressing force on the side far from the hinge, the pressing force becomes extremely large on the side near the hinge, and the packing of the part concerned is partially strongly compressed, so that the durability of the packing decreases. There was a problem of getting it.

In view of the above-mentioned problems, the present invention actively imparts vertical flexibility to the hinged portion of the inner lid so that the pressing force of the packing by the inner lid can be made uniform overall. It is an object of the present invention to provide an airtight cosmetic container capable of obtaining excellent airtight performance while improving the durability of the packing.

[0006]

In order to achieve the above object, an airtight cosmetic container according to the present invention as set forth in claim 1 comprises a container body provided with a cosmetic accommodating portion, and a hinged body attached to the container body. An openable / closable outer lid, a first hook mechanism provided between the open / close end of the outer lid, and the container body, a packing provided on a peripheral edge of the cosmetic storage section, and an outer side of the packing. A hinge pin provided on the hinge pin, an inner lid pivotally mounted on the hinge pin so as to be vertically movable and rotatable, and abutting on an upper end of the packing in a closed state; and an opening / closing end of the inner lid. A second hook mechanism provided between the container body and a closing force transmitting unit provided between a surface of the inner lid and a back surface of the outer lid and transmitting a closing force of the outer lid to the inner lid. It is constituted by having.

Further, the airtight cosmetic container according to the present invention as defined in claim 2 is configured by detachably attaching the pivot base end of the inner lid to the hinge pin.

According to the above construction, the hermetic cosmetic container according to the first aspect has an inner lid for closing the cosmetic storage portion provided on the container body, and an outer lid for entirely closing the container body.
The cosmetic container is hermetically sealed by pressing the inner lid against a packing surrounding the cosmetic container. When the outer lid and the inner lid are closed, first, the inner lid is closed and the second hook mechanism is engaged, whereby the inner lid comes into contact with the packing. At this time, since the rotation base end of the inner lid is attached to the hinge pin so as to be vertically movable, when the inner lid comes into contact with the packing when the inner lid is closed, the packing comes into contact with the packing. The pivot base end is lifted upward with the portion as a fulcrum. Therefore, the inner lid is in a state parallel to the opening of the cosmetic storage part and, consequently, the packing, and evenly contacts the entire periphery of the upper end of the packing. Then, when the outer lid is closed and the first hook mechanism is engaged, the closing force of the outer lid is transmitted to the inner lid via the closing force transmitting means, and the inner lid is pressed against the packing with a large pressing force. Then, the interior of the cosmetic container is hermetically sealed. Therefore, since the inner lid can always apply a uniform pressing force to the entire circumference of the packing, the durability of the packing and, in addition, the airtight performance of the airtight cosmetic container can be ensured for a long time.

The airtight cosmetic container according to claim 2 is
Since the rotation base end of the inner lid is detachably attached to the hinge pin, the inner lid can be removed when exchanging the cosmetics in the cosmetic accommodating part, which facilitates the replacement operation. In addition, the assemblability at the time of manufacturing the cosmetic container can be improved.
