Definitions
- the present invention relates to the pressure packaging industry. It relates more particularly to a valve comprising a reduced number of constituents.
- the search for a lowering of the cost of the valves has led to the design of valves devoid of return springs and using the elasticity of a shutter to combine the functions of shutter and valves.
- the object of the invention is to provide a valve of this type having numerous advantages over conventional valves. In addition to its qualities of operation and reliability, it works when the container is held vertically in the usual way, while most of the valves of this conventional type only work with the container turned upside down. In addition, the valve according to the invention allows the admission of additional gas into the dispensed product.
- the subject of the invention is a simplified valve for dispensing fluid products packaged in a pressure container, comprising a cup made of rigid material, sealingly fixed to the neck of the container, and a valve shutter made of flexible and elastic material, housed in an open tubular axial chimney of the cup, the obturator being hollowed out with a first blind tubular axial channel opening to the outside through an orifice surrounded by a tubular rim, for sealing the obturator on the end from the chimney outside the container, the shutter having, in the vicinity of the blind bottom of the first channel, an outer diametral annular widening forming a first valve cooperating by the elasticity of the shutter with a seat formed by the end of the chimney towards the outside of the container, the side wall of the obturator being pierced with at least one radial passage connecting the interior of the first channel to a first space delimited between the internal oi of the chimney and the external wall of the obturator comprised between the flange and the first
- the valve is characterized in that the extension has an external annular flange forming a second valve cooperating by the elasticity of the shutter with a seat formed by the internal wall of the cup in the vicinity of the chimney, valve which opens elastically.
- the second supply channel of the product to be distributed opens out, through at least one radial passage , in a second space delimited between the internal wall of the cup and the external wall of the shutter comprised between the first valve and the second valve.
- the second valve can be pierced with at least one calibrated orifice for the passage of gas making the interior of the container communicate with the second space.
- the peripheral peripheral part of the second valve bears elastically against a shoulder of the cup directed towards the interior of the container, and limiting an axial tubular extension of the chimney, of internal diameter greater than the external diameter of the first valve.
- the second valve has a peripheral marginal part folded in a skirt towards the interior of the container and bearing elastically against an axial cylindrical inner wall of the cup extending the chimney and of internal diameter greater than the external diameter of the first valve .
- the valve shown in FIGS. 1 and 2 essentially comprises a cup 1 made of metal and a shutter 2 made of flexible and elastic material, such as a rubbery polymer.
- the cup which is of the so-called "one inch” type, widely used in the aerosol industry, has an axial chimney 3 in which the shutter is housed.
- the shutter is dug with a first channel axial tubular blind 5, opening to the outside through an orifice surrounded by an annular rim 4 which bears in leaktight manner against the external end of the chimney 3.
- the shutter 2 extends to the inside the chimney 3 by a cylindrical part up to an annular widening 6 constituting a first valve which comes to bear elastically against a shoulder 7 limiting the chimney 3 towards the interior of the container 25.
- the cylindrical part of the shutter 2, between the rim 4 and the valve 6, has annular projections 27 guaranteeing a good seal, and providing a space 21 between the wall of the shutter 2 and the wall of the chimney 3.
- Two radial bores 8 and 9 communicate the space 21 with the interior 5 of the axial channel.
- tubular end of the tail of a diffuser plunger 11 or a nozzle 10 for injecting pressurized product for filling the container 25 through the valve is introduced at will.
- the tubular tail of the push button 11 communicates with the interior of the channel 5 by a radial bore 28, or also by a slot of the conventional type, not shown.
- the interior of the injection nozzle 10 communicates with the interior of the channel 5, by two radial orifices 29.
- the blind bottom 26 has an axial protuberance 30 which is inserted into the end of the nozzle 10 or of the pusher-diffuser tail 11, to ensure both good lateral support and a good sealing.
- the shutter 2 has an axial extension 12 towards the interior of the container 25.
- This extension is hollowed out by a second blind axial channel 13 which opens into the interior of the container and receives the end of a tube 23 plunging to the bottom of the container and bringing the liquid by two radial holes 17, 18 in a space 20 between the first valve 26 and a second valve 14.
- This second valve 14 has a sectional shape overturned, the marginal edge 15 of which abuts elastically against a shoulder 22 of the cup 1, extending a tubular part 24.
- the tubular part 24 has an inside diameter greater than the outside diameter of the valve 6 in the rest position.
- the second valve 14 has a calibrated bore 19 making the interior of the container communicate with the aforementioned space 20.
- the shutter 2 When filling the container 25 with pressurized product injected by the nozzle 10, as shown in Figure 2, where the path of the injected product is indicated by arrows, the shutter 2 extends from the rim 4, under the 'Effect, on the one hand, of the thrust exerted on the injection nozzle 10 and, on the other hand, under the effect of the pressure exerted by the injected product which takes off the valves 6 and 14 from their seats.
- valves 6 and 14 press elastically against their respective seats 7 and 22, thus ensuring a double seal between the inside of the container and the outside.
- the second valve 14 is in the form of a completed flange by a skirt 16, which normally seals against the tubular cylindrical wall 24 axially extending the chimney 3.
- This skirt 16 of the second valve 14 thus operates in the same way as a piston in a cylinder. It ensures sealed contact of the edge of the second valve 14 with the wall 24 of the cup 1 in all circumstances, except during filling under pressure, as indicated in FIG. 4.
- the cup 1 is crimped onto the container neck 25. It could also be snapped onto the container neck and being made of a rigid plastic, rather than metal * ot.
