Abstract
A disposable hollow bulb-shaped applicator has an ointment-permeable soft mesh membrane which covers the bulbous end of the applicator. Resilient walls surround and interconnect both ends of the applicator, and form a chamber for holding ointment therebetween. The applicator has a necked end opposite to the bulbous end which may be attached to a container of ointment. The ointment chamber of the applicator may be filled with ointment by pressurizing the container (e.g. by squeezing) to force ointment from the container into the applicator. A plug is inserted into the necked end of the applicator to prevent the flow of ointment out of the applicator through the necked end. The filled applicator is squeezed to force ointment through the soft mesh membrane and onto the surface which is to be treated by the ointment. The applicator may be discarded after use.
