Abstract
Abstract A portable dispensing device which includes a head assembly having an orifice therein and a handle assembly removably attached to said head assembly. The handle assembly includes a hollow substantially rigid reservoir housing having a piston assembly axially mounted therein and a means at the end of the housing opposite the head assembly for sealing the housing. A tapered expandable sleeve having a compensating expander therein, cooperating with a mating element within said sleeve and on the exterior of the expander for preventing rotational movement between the sleeve and the expander. A piston compressing adjusting disk is provided for axially moving the expander within said sleeve, and internal threading within said expander mates with an externally threaded feed rod which extends substantially the length of said housing and is secured to an actuating knob external of said housing.
