A viscous liquid dispensing device for a cylindrical tubular reservoir includes an internal piston wedge, a first fitting encircling an outside wall of the reservoir, and a second fitting joined with the first fitting, with the second fitting having a flip-top cap enclosing an opening of dimension and size to receive a head of the piston wedge as it is removed forwardly along the reservoir from a closed end by a pinching action of the thumb and index finger upon a tail of the piston wedge. |
