Hermetically sealed cosmetic compact case

摘要

A hermetically sealed compact (10) contains a cosmetic substance. The compact includes an integral two-piece insert (22) having a cover piece (24) coupled to a base piece (26) by an integral living hinge. The cover piece (24) of the insert has a circular cavity (30) with a pair of ridges (44,46), while the base piece has a peripheral wall (36) that slides within a groove (48) to form the seal. As the integral insert (22) obtains the closed configuration, the evacuated air makes a distinctive audible sound, indicating to the user that the hermetic seal has been established.
