Abstract (en)
[origin: US4749105A] A dispenser for paste-like substances is disclosed having a piston which is slidably disposed in a dispenser housing. The piston moves as the dispenser is being emptied toward a dispensing opening while being restrained from movement in the opposite direction. A press button is connected with a rod that extends through the piston and is coupled nonpositively with the piston through the intermediary of a locking device permitting the rod to move freely in one direction, but to carry the piston in the opposite direction. A membrane seals the end of the housing opposite the discharge opening. The piston rod is designed as a piercing tool for piercing the membrane.
