Abstract
An airtight cosmetic compact, wherein the airtight feature is created by interaction between a seal on 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 screw piece inside of said base;
- a ring free to rotate about said recess wall;
- an elevator;
- a cover;
- wherein rotation of said cover about said recess wall forms an airtight seal between said base and said cover;
- wherein rotation of said ring moves said elevator in a vertical direction;
- wherein said elevator and said screw piece each further comprise mating threads such that engagement of said threads and rotation of said elevator causes said movement of said elevator in said vertical direction.

- a cover;
- a ring;
- mating threads on said recess wall and said cover;
- a sealing element affixed to said cover, said sealing element having a chamfered perimeter;
- a chamfer on said recess wall configured to mate with said chamfered perimeter on said sealing element;
- wherein rotation of said cover about said recess wall engages said mating threads on said cover and recess wall and draws said cover towards said base;
- wherein drawing said cover towards said base engages said chamfered perimeters on said cover and said recess wall and forms an airtight seal between said base and said cover.
A cosmetic case comprising:
- a base having a recess defined by a recess wall;
- a screw piece inside of said base;
- a ring free to rotate about said recess wall;
- an elevator;
- a cover;
- wherein rotation of said cover about said recess wall forms an airtight seal between said base and said cover;
