ABSTRACT:
A dispensing device for high-viscosity compositions includes a hollow cylindrical body in which the composition is contained between a closeable discharge opening at the front end of the body and a piston movable in the longitudinal direction of the body. The piston is driven by a threaded spindle engaging a threaded nut and bearing with its front end against the rear face of the piston. The nut is slid in a direction transverse to the longitudinal axis of the body into engagement with a flange provided at the rear end of the body. A detent mounted on the nut cooperates with a longitudinal groove provided on the spindle to indicate the angular position of the spindle, thus the amount of composition being discharged, in addition to preventing the spindle from reverse rotation.
