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.
