The dispenser for the dosed delivery of fluid or paste-like substances comprises a storage container (3) with its open bottom end closed off by an axially movable piston (32). A dispensing head (2) includes a bell-shaped dispensing pump (10). An outlet valve (8) as part of the pump neck (12) is made in one piece with it so that by a simple operating stage the complete upper through-passage of the pump neck can be closed off by a valve plate (20). The valve plate, which is preferably made of rubber, has a central hole which is fitted over a pin (11) in the pump neck. |
