发明名称 Valved cosmetic applicator
摘要 An applicator for applying cream to a person's lips including a tube for the cream having a deformable portion adapted to be squeezed to displace a quantity of cream into an applicator tip mounted on the tube. The tip includes a valve structure cooperable with the outlet of the tube to automatically close the outlet when a closure cap is applied over the applicator, to prevent undesired oozing. A spring engages the tip to open the valve after the cap is removed from the applicator.
