Abstract: An applicator assembly includes at least one ampoule formed of a frangible material and containing liquid to be applied, a body having a proximal end, a distal end, and an interior portion defining a chamber adapted to receive the at least one ampoule, an application member attached to the distal end of the body, an actuator projecting from the body operable to fracture the at least one ampoule, a trench formed in a surface of the body, and a vent disposed through a surface of the trench.

Abstract: An applicator assembly includes a plurality of ampoules formed of a frangible material and containing liquid to be applied, a container having a proximal end, a distal end, and an interior portion defining a chamber adapted to receive the plurality of ampoules, an application member attached to the distal end of the container; and at least one actuator projecting from the container, wherein the at least one actuator is actuatable to independently fracture the plurality of ampoules, thereby independently releasing the liquid into the application member. The at least one actuator may be moveable from a first position to a second position, the applicator having a smaller profile when the actuator is in the second position than when the actuator is in the first position.

Abstract: A pump piston assembly has a pump cylinder, at least one hollow piston slidably mounted for reciprocating motion in the pump cylinder, the piston having an inner surface of a first diameter and an outer surface of a second diameter, and a liner sleeve of a different material from the piston mounted on the inner or outer surface of the piston with a close or friction fit to the diameter of the piston surface on which it is mounted. The liner sleeve is of an acoustic dampening material which has a lower acoustic frequency than the piston material and is configured to absorb harmonic acoustic vibrations resulting from reciprocation of the piston in the cylinder.
