ABSTRACT:
A dispenser for paste products comprises a container and a hollow dispensing head having a pumping member mounted on its interior, an actuating lever for the member, and a delivery conduit which is associated at one end with the pumping member. The head has a tubular extension facing the top end of the container, which matches the contour of the container. The extension is releasably attached to the container, thereby the latter can be provided in the form of a replaceable refill container. To extend the working life of the dispensing head, the pumping member has a leaf spring associated therewith which acts against the push force from the actuating lever.
