Abstract
A dispenser for pasty compositions, particularly a toothpaste dispenser, with pump-like actuation for the portioned delivery of the content from a nozzle discharge channel, in which connection the pump chamber, which can be reduced in volume by displacement of an actuator against spring action, lies, as seen in the flow path, between two valves, one of which is connected with the storage space and the other with the nozzle discharge channel. By a simple structural shape which is easy to manufacture and easy to use, the two valves are located on a straight-line which extends along their extension through the nozzle discharge channel and the actuation of the pump takes place transverse to said straight line.
