ABSTRACT:
A dispenser for the portioned dispensing of its contents, in particular a pasty composition, has a piston which is displaced stepwise in the emptying direction, an actuating handle which is displaced against spring force, and an outlet opening of the dispensing tube, which outlet opening can be closed by a closure part formed on the actuating handle. Also, upon a return movement of the actuating handle (6), the closure part (10) closes the outlet opening (11) by form-locked application, and pulls the dispensing tube (7) out of its dispensing position into a position of rest.
