Abstract

Simplified valve for aerosol conditioning, for the distribution of fluid products packaged in a container (25) under pressure, comprising a cupel (1) in rigid material tightly coupled in the neck of the container and a valve (2) with valve, in light and elastic material, housed in an open tubular axial neck or chimney (3) of the cup (1), the plug (2) being hollow with a first, tubular, blind, axial channel (5) that opens out to the outside by an orifice surrounded by an annular rim (4), sealingly fastening the obturator (2) at the end of the neck (3) outside the container (25) presenting the obturator (2) in front of the blind bottom (26) of the first channel ( 5), an outer diametral annular widening forming a first valve (6) cooperating with the elasticity of the obturator (2) with a seat (7) formed by the very end of the (3) towards the interior of the container (25), the side wall of the shutter (2) is cut at least by a radial passage (8, 9) joining the interior of the first channel (5) with a first space (21) delimited between the internal wall of the neck (3) and the external wall of the shutter (2) comprised between the rim (4) ) and the first valve (6); the first channel (5) receives externally sealed, the end of a nozzle (10) filling the container with product injected under pressure through the valve by the axial expansion of the obturator (2) from the flange (4), separating the first valve (6) from its seat (7) by effect of the pressure of the fluid injected by the nozzle and, alternatively, the end of the tube (11) of the pusher-diffuser, for the distribution at will of the packaged product, by the limited axial expansion of the obturator (2), under the effect of the manual pressure exerted on the pusher-diffuser, whose obturator (2) has an axial prolongation (12) directed towards the interior of the container (25), communicated by a second blind axial channel (13) that opens into the interior of the container (25) and receives the end of an immersion tube (23) through which the product to be distributed arrives, whose tube is submerged to the bottom of the container (25). ) and whose valve is acteriza because the extension (12) has a peripheral outer collar forming a second valve (14) cooperating by elasticity of the obturator (2, 22, 24) with a seat formed by the inner wall of the cup (1) facing the neck (3) ), whose valve (14) opens elastically under the effect of the pressure of the fluid injected during the filling, but which remains closed, in elastic support by its seat (22, 24), at the moment of the distribution of the product; the second channel (13) of arrival of the product to be dispensed ends, at least in a radial passage (17, 18) in a second space (20) delimited between the internal wall of the cup (1) and the external wall of the shutter (2) comprised between the first valve (6) and the second valve (14).
