发明名称 Cosmetic container having an inner sleeve for creating torque
摘要 A cosmetic container, such as a lipstick container, having a tubular inner sleeve rotatable within a tubular outer sleeve and a cosmetic carrier positioned therein. The cosmetic container may be extended and retracted for the application and storage of the cosmetic. The inner sleeve includes a shank defining a longitudinal slot for receiving lugs extending radially outward from the cosmetic carrier and a manually rotatable base. The shank includes at least one radially outwardly facing rib extending circumferentially along at least a portion of the shank. Preferably a plurality of ribs extend from the inner sleeve and are positioned in a flexible region thereof. The outer diameter of the ribs is at least equal to the inner diameter of the outer sleeve to create torque therebetween.
