DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The present invention relates to a hermetically sealed cosmetic container for containing cosmetic material in a portable fashion, and more particularly, to a hermetically sealed cosmetic container having a refill case detachably housed in a container housing, the refill case accommodating volatile cosmetic material therein.


BACKGROUND ART

Generally, cosmetic containers are used to carry cosmetic materials. Such a cosmetic container has a container housing accommodating cosmetic material therein, and an outer lid openably and closably hinged to a rear end of the container housing for covering the entire upper side of the container housing. The cosmetic container has a general structure which includes a hook mechanism disposed between the front ends of the container housing and the outer lid for keeping the outer lid closed, and a button projecting from the front end of the container housing for releasing the hook mechanism.
If the cosmetic material is a volatile cosmetic material, then the hermetic seal of the cosmetic container becomes important. There have been proposed various hermetically-sealed cosmetic containers which provide an increased hermetic sealing capability between the container housing accommodating cosmetic material therein and the outer lid for opening and closing the container housing. (See i) Japanese Laid-open Patent Publication No. 9-37839.) Some hermetically sealed cosmetic containers include an inner lid positioned between the container housing and the outer lid to provide a sealing structure between the inner lid and the container housing. (See ii) Japanese Laid-open Patent Publication No. 8-347 and iii) Japanese Laid-open Patent Publication No. 9-37838.) Recent years have seen a cartridge-type refill case detachably housed in a container housing and accommodating volatile cosmetic material therein. (See iv) Japanese Laid-open Patent Publication No. 9-65920 and v) Japanese Laid-open Patent Publication No. 9-98829.)
Specifically, the refill case comprises an inner lid openably and closably attached to the inner tray accommodating cosmetic material therein. An elaborate sealing mechanism is disposed between the inner tray and the inner lid and an elaborate detachable attaching mechanism is used between the refill case and the container housing. There is known a detachable attaching mechanism which allows an inner tray accommodating a non-volatile cosmetic material to be detachably housed in a container housing without use of an inner lid. (See vi) Japanese Laid-open Patent Publication No. 9-47319.) In a design having an inner lid disposed between the container housing and the outer lid, an elaborate mechanism is employed to open and close both lids because the outer and inner lids provide a double lid mechanism. (See vii) Japanese Laid-open Patent Publication No. 8-348 and viii) Japanese Laid-open Patent Publication No. 9-98828.)
The hermetically sealed cosmetic container shown in i) Japanese Laid-open Patent Publication No. 9-37839 includes an annular elastic gasket disposed below the outer periphery of an opening of a cosmetic accommodating region of the container housing, and an annular ridge projecting on an inner surface of the lid. When the lid is closed, the annular ridge and the annular elastic gasket are pressed against each other below the opening of the cosmetic accommodating region. The hermetically sealed cosmetic container disclosed in ii) Japanese Laid-open Patent Publication No. 8-347 has an annular elastic gasket of U-shaped cross section which is installed from above onto a peripheral edge of an opening of an inner tray and an elastic gasket disposed on the lid. When the lid is closed, the annular elastic gasket on the inner tray and the elastic gasket on the lid are pressed against each other. The hermetically sealed cosmetic container with the inner lid shown in iii) Japanese Laid-open Patent Publication No. 9-37838 includes an annular elastic gasket disposed below the outer periphery of an opening of a cosmetic accommodating region of the cont
