Abstract
An applicator for local application of a liquid to a person's skin. The applicator includes a porous dome, a chamber under the dome, a squeeze bottle providing a reservoir containing the liquid, and a tube from the squeeze bottle to the chamber. The porous dome has pores sized to provide liquid transport therein by capillary action. The chamber provides a location for liquid in position to be transported into dome. Increased pressure in the reservoir from squeezing the bottle causes liquid to flow from the reservoir through the tube to the chamber, and decreased pressure in the reservoir from releasing the bottle causes excess liquid in the chamber to flow from the chamber through the tube to the reservoir. The applicator can include a squeeze bottle having a relatively rigid molded open-end portion connected to a porous dome and an integral flexible, blow-molded reservoir portion that can be squeezed to a reduced volume condition to deliver liquid to the dome and has memory to return to an unsqueezed volume condition.
