DESCRIPTION:

BRIEF SUMMARY
DETAILED DESCRIPTION OF THE INVENTION

1. Technical Field
The present invention relates to a compact for a cosmetic substance which is provided with a lid assembly comprising an inner lid member that seals an inner dish containing a cosmetic substance and an outer lid member that doses the entire compact, and, in particular, to a compact for a cosmetic substance having a closable structure whereby pressure from the inner lid causes a resilient sealing member provided on an edge portion of an opening of the inner dish to form a double airtight state.
2. Background Art
As can be seen from Japanese Utility Model Application Laid-Open No. 7-3510, which discloses a typical example of a compact for a cosmetic substance, a known type of compact for a cosmetic substance has a configuration comprising a main compact body having an outer shape that is roughly rectangular or oval, wherein a concave portion into which is assembled an inner dish that accommodates a cosmetic substance is provided in one side half thereof and another concave portion that accommodates a cosmetic implement such as a powder puff is provided in the remaining side half. A lid assembly formed of an inner lid member that seals the surface of the inner dish and an outer lid member that doses the entire compact is provided on one edge portion of the compact, to form a hinged structure that can be freely opened and closed.
Either of the following methods is employed as means of releasing the lid assembly: (1) a method of releasing both the inner and outer lid members together by a "one-touch" operation, such that the engagement between the outer lid member and the main body of the compact is canceled whereby, at the same time, the engagement between the inner lid member and the inner dish is canceled, or (2) a method of releasing the inner lid member after the outer lid member has been completely released.
However, method (1) has a problem in that a large operating force is required for releasing the lid assembly, because the disengagement of both of the lid members must be done simultaneously, and method (2) has a problem in that the operation of releasing the lids is complicated, because each lid member requires a separate release operation.
In addition, there are many various volatile substances comprised within cosmetic substances, so a compact that is designed to hold such a cosmetic substance has to have a structure that is capable of being closed so that the cosmetic substance contained therein is in a sealed state, to ensure that such volatile substances do not evaporate.
Specific examples of such a structure are known, as disclosed in Japanese Utility Model Application Laid-Open Nos. 3-34412 and 7-3510.
In the former configuration, disclosed in Japanese Utility Model Application Laid-Open No. 3-34412, an inner dish is provided fitted into an inner accommodation portion formed in a main container body and a sealing member consisting of a resilient material is attached to the inner surface of a lid body of the main container body. The vicinity of the peripheral edge portion of this sealing member is formed to have an inward-facing tapered surface on an outer surface of an annular skirt portion that protrudes so as to engage with the peripheral edge of the opening of the inner dish.
When the container is closed, the skirt portion of the sealing member engages inward of the inner dish from the upper opening thereof, and the outer surface of the skirt portion is pressed elastically into contact with the inner peripheral edge of the opening of the inner dish, to form an airtight seal for the interior of the inner dish. However, this configuration in which the skirt portion of the sealing member is inserted into the inner dish when the container is closed has a disadvantage in that only a limited quantity of cosmetic substance can be placed in the inner dish, to ensure that the extreme edge portions of the skirt portion do not strike the upper surface of the cosmetic substance.
In the latter configuration, disclosed in Japanese Utility Model App
