Patent

CA 2640063

The invention relates to a dispensing device for dispensing a foam, comprising a manually compressible container (2) for storing a liquid and air, which container comprises an opening (3), a rigid housing (4, 5) to be fitted in or on the opening, the housing comprising an air passage (11, 12) and a liquid passage (9), which are in communication with a dispensing passage (14) which ends in a dispensing opening (8), and a valve body (6) which, in a rest position, covers a mouth of the liquid passage and a mouth of the air passage (10) in a sealing manner in order to prevent a flow from the liquid passage and the air passage to the dispensing passage, and which, during dispensing, opens the mouth of the liquid passage and the mouth of the air passage in order to allow mixing of air and liquid to take place in the dispensing passage. The invention is characterized by the fact that the mouth of the air passage and the mouth of the liquid passage are- substantially annular and are arranged substantially concentrically with respect to one another.

L'invention concerne un distributeur de mousse comprenant: un réservoir comprimable à la main (poire) qui renferme de l'air et un liquide et qui présente une ouverture; un boîtier rigide s'emboîtant sur ou dans l'ouverture et comprenant un passage pour l'air et un passage pour le liquide qui communiquent avec un conduit de distribution débouchant sur un orifice de distribution; et un corps de soupape qui, à l'état de repos, obture une ouverture du passage pour liquide et une ouverture du passage pour air et empêche ainsi l'air et le liquide de passer dans le conduit de distribution et qui, pendant la distribution, ouvre lesdites ouvertures et permettent à l'air et au liquide de se mélanger dans le conduit de distribution. Cette invention se caractérise en ce que l'ouverture du passage d'air et l'ouverture du passage de liquide présentent une forme sensiblement annulaire et sont disposées de manière sensiblement concentrique l'une par rapport à l'autre.
