Abstract
A lipstick container cover has a cup-shaped insert which sealingly telescopes over a sealed base assembly. The cover insert has an inward peripheral rib which makes line sealing contact with the sleeve. A bump formed on the sleeve raises the rib to vent pressure caused either by pushing the cover on the lipstick container or pressure build-up due to vaporizing solvent after the cover is fully installed. Venting the pressure in the container avoids the lifting off of the cover after installation. Otherwise such lifting unseals the container.
