Abstract
A non-aerosol liquid dispenser comprising a container having a preformed elastomeric diaphragm secured therein. The diaphragm stretches during filling of the container to create a return force which causes dispensing when a manually operated valve is actuated. The diaphragm includes a one-way valve which, during filling of the container, operates to permit air trapped beneath the diaphragm to enter the space above the diaphragm where the liquid is being supplied. The trapped air is expelled during the first actuation of the manually operated valve.
