Abstract

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.

A dispensing container for the fluent material;

an applicator tip movable axially on said container and extending forwardly of said container and having a passage for fluent material dispensed from said container, said tip having a forward outlet at the end of said passage;

valve means within said passage disposed inwardly of said outlet for preventing and permitting flow of fluent material from said container to said passage;

a removable cap disposed over said container and tip to enclose said tip and its passage; and

means responsive to application of said cap to said container for moving said tip axially of said container to close said valve means to prevent flow of fluent material from said container into said passage.

2. In an applicator for fluent material as defined in claim 1;

means for opening said valve means to permit flow of fluent material to said passage upon removal of said cap from said container.
