<p>A sealed lipstick dispenser assembly (10) has a base (14), a sleeve (16) mounted within the base (14) containing a lipstick pomade (18), and a cover (12) mounted over the base and receiving a portion of the sleeve (16) and pomade (18) within a hollow interior. A bellows-like sealing member (20) defines a sealing surface on one end (22), and a plurality of infolded or pleated portions (26) to permit axial extension and retraction of the sealing surface. The sealing member (20) is mounted on the base of the cover (12) within the hollow interior, with the sealing surface (22) on its free end. Upon closure of the cover (12) on the base (14), the sealing surface (22) is pressed into engagement with a lip of the sleeve (16) due to the resilient nature of the infolded portions (26) of the sealing member (20) to form a fluid-tight seal, and thereby seal the lipstick pomade (18) within the sleeve (16).</p> |
