Abstract
An airtight cosmetic compact, wherein the airtight feature is created by interaction between a seal facing downwardly from the inside of the cover and the upwardly facing recess of the base. The cover locks on the base by either thread elements on both cap and base or by bayonet like cams, allowing the cover to be twisted on the base compressing the cover against the base and engaging the seal with the base recess. By compressing the seal against the base and holding it in place through the threaded engagement the air-tightness of the compact is achieved and guaranteed.

A cosmetic case comprising:
- a base having a recess defined by a recess wall;
- a ring free to rotate about the recess wall and retained by the base;
- a cover;
- a hinge affixing the cover to the ring to form a cover assembly;
- wherein rotation of the cover assembly about the recess wall forms an airtight seal between the base and the cover;
- wherein the ring is retained to the base with at least one groove extending around at least a portion of the recess wall engaged with at least one protrusion extending inwardly from the ring, said at least one groove retaining the ring by the at least one protrusion while allowing rotation of the ring through at least a predetermined arc about the recess wall;
- wherein the at least one groove further comprises at least one riser such that rotation of the cover assembly engages the at least one protrusion with the at least one riser and moves the cover assembly away from the base.
