Abstract

Abstract An applicator including a tubular collapsible body containing a liquid preparation, one end being permanently closed, the other end being initially closed and having means for opening it to provide an outlet orifice. Surrounding the orifice and attached to the applicator is a collar made of absorbent spongy material impregnated with a protective substance in ointment form. Desirably the liquid and ointment are silicone. The collar is somewhat larger in diameter than the ear canal and is desirably frusto-conical in outer contour so that it can be inserted into the meatus of the ear and partially into the adjacent portion of the ear canal. A slight twisting of applicator causes the collar to deposit a coating of ointment on the skin it contacts, and the user then squeezes the applicator body to force some of the liquid into the ear canal.
