Lipstick case with resilient friction tab
摘要:
A cosmetic container comprising a tubular base having an internally threaded lower section and an internally smooth upper section mates with a tubular rotatable sleeve extending up from the base. A tubular telescoping screw assembly has one part secured to the base and one part secured to a pomade cup keyed for rotation with the sleeve. A downward tab is formed integrally with the sleeve and has an outward nib on its lower end which presses against the smooth inner surface of the upper section of the base. The nib exerts a frictional drag on the rotation of the sleeve with respect to the base to give the operation of the container a silky "feel".
