ABSTRACT:
A device for dispensing a fluid or plastic material from the chamber of a housing to brush bristles connected to said housing so that the material, such as a cleansing material, can be used in combination with the brush bristles. A reciprocal rod has an annular cavity adapted to fit a plurality of telescopic cylindrical members therein. A piston is preferably connected to one of said members and forms a movable wall of said chamber. Reciprocal movement of the rod causes the piston to be shifted longitudinally within the housing to selectively force material from said chamber through a pressure sensitive valve to the bristles. The telescopic members allow for the device to be of a minimum length while still allowing for substantially complete dispensing of the material within the chamber. Optionally, a separate container can be used to supply material to the housing chamber.
