ABSTRACT:
A dispenser for dispensing metered amounts of liquid or paste-like products has a cylindrical reservoir having an open bottom and an upper end with an intake valve. A plunger is arranged axially movably in the cylindrical reservoir and closes off the open bottom of the cylindrical reservoir. A dispensing head is arranged on the upper end of the reservoir. The dispensing head has a bell-shaped dispensing pump having elastic sidewalls and a pump head with a through opening having an outlet valve. The dispensing pump together with the intake valve and the outlet valve delimits a closed pump chamber. The outlet valve is manufactured as a monolithic part of the pump neck such that with a simple working step the entire through opening of the pump neck is closable by a valve flap of the outlet valve.
