SEALED FLUID DISPENSING DEVICE

摘要

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).
