CA 2164341

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.

On décrit un dispositif de production et de distribution de mousse qui comporte un récipient rétractable pour liquide (30) et une pompe à mousse (36), fixée à sa sortie, comprenant deux enceintesdont la première est soudée dans le goulot du récipient et la deuxième est logée de façon télescopique dans la première. Ces deux enceintes assemblées définissent une chambre pneumatique (104) et une chambre à fluide (105) dont les sorties respectives fusionnent au niveau de la sortie du dispositif de production de mousse. La chambre à fluide (50) reçoit un liquide du récipient (30) et, quand le deuxième élément se déplace par rapport au premier, la chambre à fluide (50) est mise sous pression pour ouvrir une soupape de sortie (20) et de l'air est simultanément expulsé par la sortie. Le liquide et l'air se mêlent en traversant un réseau (84) de fils, de plastique ou de tissu et produisent ainsi de la mousse. Un boîtier de distributeur reçoit de façon réversible le récipient rétractable pour liquide et la pompe à mousse. Ce distributeur comporte un poussoir pivotant qui est raccordé à la deuxième enceinte pour activer la pompe.
