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, supported by a seal surrounding the pump body.
- the distribution of a dose of product created, in the capacity tank fixes a depression 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 flat ring forming a joint, the free edge of which is in leaktight support towards the outside under a frustoconical shoulder carried by the pump body or said flange and is likely to deform elastically under the effect of an internal depression to allow air intake.
- said frustoconical shoulder is produced directly on the external lateral wall of the pump body.
- said frustoconical shoulder is carried by a collar fitted on said pump body.
- said ring has at least one radial slit extending from the free edge to facilitate its deformation.
- the inner edge of said ring is in the closed position of the pump bent inwardly under stress by having a portion of its outer face in contact with said shoulder.
- the internal face of said ring comprises a peripheral wedging groove intended to receive a rib formed on the upper periphery of the reservoir.
- the device of the invention ensures sufficient air intake while ensuring hermeticity of the distributor.
- the flexibility and elasticity of the annular seal can be adjusted according to the level of depression likely to be created created in the tank by the distribution of the product.
- the dynamic semi-sealing of the dispenser is obtained according to the invention by the valve effect resulting from the cooperation between the ring and the shoulder.
- the device of the invention can be applied to precompression pumps with or without a vent orifice, without it being necessary to modify their structure.
- FIG. 1A shows a sectional view of an embodiment of the device of the invention in the rest position
- FIG. 1B shows a sectional view of the device of Figure 1A in the air intake phase
- - Figure 2A shows a sectional view of another embodiment of the device of the invention in the rest position
- - Figure 2B shows a sectional view of the device of Figure 2A in the air intake phase
- FIG. 3 shows a perspective view of the flat annular seal used in the invention.
- the device of the invention is intended to be used in liquid product distributors to ensure, after each distribution, the air intake in a rigid tank R (shown partially in the figures) containing the liquid product.
- This dispenser is equipped with an atmospheric pump P provided in particular with a cylindrical-conical body C surmounted by a support flange S fixed on the neck to the reservoir R by bearing on a seal enclosing the body C.
- the distributor shown comprises, in addition, a push-button K carried by a distribution head T mounted on the nozzle tube of the pump P as well as a metal assembly sleeve D crimped on both the flange S of the pump and on the neck of the tank R, trapping the seal.
- the device of the invention comprises a flat ring 1 forming a seal, provided with a free edge 10 capable of deforming elastically under the effect of an internal depression to allow air to be taken up in the reservoir R.
- the internal face of the ring 1 comprises a wedging groove 12 intended to receive a rib N of complementary profile formed on the upper periphery of the reservoir R.
- the frustoconical shoulder 20 is produced directly by molding in one piece with the external side wall of the body C of the pump P.
- the pump P is provided with a vent orifice E passing through the wall of the body C above the shoulder 20 and opening out above the ring 1 inside the socket D.
- the push-button K goes up with the nozzle tube of the pump P, creating a vacuum inside the reservoir R.
- This depression causes the elastic deformation of the free edge 10 of the ring 1 towards the inside of the reservoir R.
- the pump P has no vent orifice.
- the frustoconical shoulder 20 is carried by a collar 2 fitted on the body C of the pump.
- the collar 2 abuts upwards against the flange S.
- the lower part of the collar 2 carrying the shoulder 20 is in tight radial tightening with the external lateral wall of the body C while the part cylindrical upper delimits with the body C an intermediate space.
- FIG. 3 represents an embodiment of the flat ring 1 used in the device of the invention.
- the ring 1 has at least one and here three slots 13 which extend radially from the free edge 10 and facilitate its elastic deformation.
- the length of the slots is between a third and a half of the width of the ring 1
