Abstract (en)
[origin: EP0452260A2] A dispenser (401) has a pumping device (411) which has a support (413) with a plate-shaped support part (413a), a pump element (411) which can be pressed manually against the latter and at least one pump chamber (439). The latter is connected by means of an outlet valve (437) to the side of the pump element (431) which is accessible from the outside. The pump element (431) and the outlet valve (437) are formed by an elastic diaphragm (433a) which has an outlet hole (433c), and by an essentially dimensionally stable disc (435) which is connected to said diaphragm. When the pump element (431) is non-operative the outlet valve (437) is closed, in which case at most a very small amount of the product to be stored which is present in any case in the outlet hole (433c) can come into contact with the ambient air. If a person manually presses the pump element (431) against the aforesaid support part (413a), the product (451) to be dispensed opens the outlet valve (437). <IMAGE>
