ABSTRACT:
A tubular container, at least partially closed at one end and having a nozzle at the other end, encloses a cylindrical valve head having an applicator brush attached to one end and a valve stem connected to the other end which extends along the axis of the container. When the applicator brush is extended to operating position, one end of the valve head seats against the inside shoulder of the nozzle, preventing liquid from leaking out. In one embodiment, in which the valve head is double-ended, a partition separates a large liquid reservoir at one end of the container from an auxiliary reservoir adjacent the nozzle. When the container is upended, the brush is retracted, engaging a valve seat in the partition, trapping liquid in the auxiliary reservoir. The disclosed embodiments include at least one liquid-pervious guide rigidly fixed inside the container wall and having a circular opening disposed to accommodate the valve stem in free moving axial relation. In a modification, the valve head is single-ended, and the partition is replaced by a second liquid-pervious guide which also accommodates the valve stem in free moving relation. In both types, the applicator may be manually actuated by a plunger which protrudes axially through the end of the container opposite the nozzle. Another feature relates to liquid refilling means.
