Definitions
- the present invention relates to an air intake device for a liquid product dispenser.
- Liquid product dispensers are generally equipped with a rigid reservoir and an atmospheric pump provided in particular with a cylindrical-conical body and a support flange cooperating, where appropriate, with a cup or an assembly socket crimped onto the neck of the tank.
- the distribution of a dose of product created in the capacity tank fixes a vacuum which must be compensated by an air intake of corresponding volume.
- the pump bodies are provided with so-called vent orifices capable of making the interior volume of the tank communicate with the outside during the final phase of the distribution.
- Another embodiment making it possible to restore the balance of the pressures necessary for the proper functioning of the distributor consists in providing a clearance between the fixing flange and / or the pump body, on the one hand, and the neck of the reservoir and / or the assembly cup, on the other hand so as to allow an air suction flow.
- the means forming a vent are the seat of leaks of liquid product, especially when the level of the product is above the vent, either by construction or by a specific use of the dispenser, inverted position.
- the present invention aims to solve these technical problems satisfactorily without modifying the structure of traditional distributors.
- an air intake device characterized in that it comprises a sleeve intended to be mounted around said pump body, under said flange and the lower part of which is provided a collar forming a vent, the internal wall of which, intended to come into radial tightening with said body, has a surface condition such that said collar is both tight vis-à-vis the liquid product and permeable to air.
- the surface of the internal wall of said collar has grains resulting from an electroerosion treatment.
- the sleeve defines with the wall of said body and above the level of said collar a free space capable of communicating with the outside by forming at least one suction duct for the air intake.
- said free space is delimited by at least one groove extending over the external lateral wall of the body of the pump. This variant applies more particularly to pumps fitted from their construction with a vent orifice.
- the inside diameter of said sleeve in the free state is then less than or equal to the outside diameter of the body in the vent zone.
- the upper edge of the sleeve then abuts against said collar.
- said free space is formed by the intermediate volume situated between the internal wall of the sleeve and the external lateral wall of the body of the pump, above the collar.
- the upper part of said sleeve is then provided with slots allowing the lateral entry of the air intake.
- the collar has a frustoconical profile while the sleeve is cylindrical and has a beveled upper edge.
- the device of the invention makes it possible to carry out sufficient air intake while ensuring hermeticity of the distributor.
- the static tightness of the collar vis-à-vis liquids can be adjusted according to the viscosity of the product to be packaged.
- the sleeve of the invention can be put in place after manufacture of the pump without it being necessary to modify the latter.
- this sleeve applies to pre-pressure pumps with or without a vent orifice.
- FIG. 1A represents a sectional view of a first embodiment of the device of the invention in the rest phase.
- Figure 1B shows a partial top view and in section along BB of the embodiment of Figure 1A.
- Figure 1C shows a sectional view of the embodiment of Figure 1A in the air intake phase.
- FIG. 2A represents a sectional view of a second embodiment of the device of the invention in the rest phase.
- Figure 2B shows a perspective view of the sleeve of the embodiment of Figure 2A.
- Figure 2C shows a sectional view of the embodiment of Figure 2A in the air intake phase.
- FIGS. 1A and 1 C show a detailed view in section of the embodiment of the sleeve of the invention corresponding to Figure 1B, in a plane passing through the median axis of a groove of the pump body.
- the device shown in FIGS. 1A and 1 C is intended to be used in liquid product dispensers equipped with a rigid reservoir R (partially shown), an atmospheric pump P provided in particular with a cylindroconical body C surmounted by a support flange S capable of being fixed to the tank coi R.
- the distributor shown also comprises a push button K carried by a spray head T mounted on the nozzle tube of the pump P as well as a metal socket of assembly D crimped both on the collar S of the pump and on the neck of the reservoir R by trapping a seal J.
- the device of the invention is intended to ensure the return of air to the reservoir R after each distribution a dose of product by pump P.
- This device comprises a sleeve 1 made of suitable elastomer or plastomer material and intended to be mounted around the body C of the pump P, under the flange S.
- the lower part of the sleeve 1 is provided with a collar 10 forming a vent which preferably has a frustoconical profile and the internal wall of which comes in semi-sealed radial tightening against the external lateral wall of the body C as shown in detail in FIG. 3.
- the surface condition of the internal wall of the collar 10 is such that the semi-sealed contact between said collar and the body C jointly ensures the seal with respect to the liquid product contained in the reservoir R whatever its orientation and the air permeability, at least from the outside towards the inside the tank R.
- the appropriate surface condition is irregular so as to delimit a fine network of small channels allowing the passage of air, while preventing the flow of the product. This network is produced, for example, by local electro-erosion of the internal wall of the collar 10.
- EDM will be adjusted so as to create a grain size g and therefore determined channel sections.
- the sleeve 1 delimits with the wall of the body C of the pump P, above the level of the collar 10, a free space capable of communicating with the external atmosphere by forming at least one suction duct for the air intake. .
- the pump P is provided with a vent orifice E passing through the wall of the body C and communicating with the outside, above the upper edge of the sleeve
- the sleeve 1 has everywhere, in the free state, an internal diameter equal to or slightly less than the external diameter of the body C in the vent zone.
- the free space is therefore here delimited by at least one and, preferably, three grooves e extending on the external lateral wall of the body C parallel to its generatrices as shown in FIG. 1 B.
- the body C of the pump P has no specific vent orifice.
- the sleeve 1 has at its lower part a collar 10 identical to that of the embodiment of FIGS. 1A and 1 C which is in semi-sealed radial clamping around the body C of the pump P.
- the sleeve 1 is here produced with an internal diameter greater than the external diameter of the body C.
- the free space is here formed of the intermediate cylindrical volume i situated between the internal wall of the sleeve 1 and the external lateral wall of the body C of the pump P, above of the collar 10.
- the sleeve 1 is further provided, at its upper part, with slots
