<p>There is disclosed a foaming de- vice for dispensing foam. The device in- cludes a collapsible liquid container (30) and a foam pump (36) attached to the con- tainer outlet. The foam pump includes two enclosures, the first being bonded in the throat of the container and the sec- ond being telescopingly received in the first. When assembled, the two enclosures define an air chamber (104) and a fluid chamber (50) each having outlets which merge by the foamer outlet. The fluid chamber (50) accepts liquid from the con- tainer (30), and when the second member is moved with respect to the first mem- ber, the fluid chamber (50) is pressurized to open an outlet valve (20), and air is si- multaneously expelled through the outlet. The liquid and air commingle as they pass through a wire, plastic or fabric mesh (84) thereby forming the foam. There is in- cluded a dispenser housing for releasably receiving the collapsible liquid container and foam pump. The dispenser includes a push button pivotally attached thereto which is coupled to the second enclosure so that as the push button is moved the pump is actuated.</p> |
