摘要

A pump for discharging doses of liquid, gel-like or viscous substances from a container, having a pump body made of a flexible and elastic material which can be squeezed together to form a suction vacuum and delivers the liquid via an outlet valve, which opens under overpressure. In order to provide a pump of the type mentioned, which is of simple construction and is at the same time self-priming, provision is made for the outlet valve to be configured as a valve plate which closes the pump body at the top, is molded integrally onto the latter, is convex in the delivery direction, and has an incision which forms the valve outlet in the form of a lip seal.
