Patent

CA 2330800

The invention concerns a fluid dispensing device (6), in particular of liquid and/or pasty substance, comprising a reservoir (1) capable of being actuated with pressure, and a dispensing head (2, 3, 4) communicating with the reservoir to obtain at least a partial fluid flow (6) towards an outlet (5a). The invention is characterised in that the head comprises a fixed body (2) and a membrane (3) mounted tight over part at least of the fixed body (2). The tightening of the membrane (3) is selected to enable, when the reservoir is actuated by pressure, the fluid to flow outside the reservoir through the peripheral space (7) between the membrane (3) and the fixed body (2).

L'invention concerne un dispositif distributeur de fluide (6), notamment une substance liquide et/ou une pâte. Ce dispositif comprend un réservoir (1) susceptible d'être actionné par pression, et une tête débitrice (2, 3, 4) communiquant avec le réservoir pour obtenir un écoulement au moins partiel du fluide (6) vers un orifice de sortie (5a). Selon l'invention, la tête comprend un corps fixe (2) et une membrane (3) montée serrée sur une partie au moins du corps fixe (2). Le serrage de la membrane (3) est choisi pour permettre, lors de l'actionnement par pression du réservoir, un écoulement hors du réservoir par l'espace périphérique (7), entre la membrane (3) et le corps fixe (2).
