Definitions
- the present invention relates to a fluid dispenser pump, and a fluid dispenser device incorporating such a pump.
- Fluid product dispensing devices usually include a reservoir on which is mounted a dispensing member, such as a pump.
- a fixing element such as a screwable or snap-on ring or a crimpable capsule.
- the seal between the reservoir and the fixing element is produced by means of a seal called a neck seal. Since the manufacturer of the pump is generally different from the manufacturer of the product to be dispensed, the pump is manufactured, assembled and delivered to the manufacturer of the product which fills the reservoir and then performs the step of fixing said pump to said reservoir by means of the fixing element.
- the pump In order to provide the fluid manufacturer with a complete and pre-assembled pump sub-assembly, the pump is generally delivered complete and ready to assemble, ie incorporating all the elements essential to its assembly, including the aforementioned neck seal.
- This neck seal is generally pre-mounted around the pump body of the pump, so that after filling the reservoir, the manufacturer of the fluid product only has to place the pump on the reservoir neck and the '' assemble using the fixing element.
- Document EP-1 050481 discloses such a device.
- the pre-assembly of the seal around the pump body is generally carried out by fitting the said seal onto the pump body.
- the internal peripheral surface of the seal is not generally annular, but has several points of contact with the pump body, in general three which are distributed regularly around the pump body, and which ensure the positioning and the maintenance of the joint after this fitting.
- the seal therefore exerts a radial force on the pump body, this must be sufficient to prevent displacement of said seal during storage or transport.
- This radial force exerted by the seal on the outside of the pump body can cause a slight deformation of the lateral surface of said pump body, which can lead to leaks at the sliding surface of the piston inside the body. pump.
- the object of the present invention is to provide a fluid dispensing pump which does not have the abovementioned drawbacks.
- the present invention therefore aims to provide a fluid dispensing pump which is simple and inexpensive to manufacture to assemble, and which is reliable to use.
- the present invention aims to provide a fluid dispensing pump which limits the risks of leakage.
- the present invention therefore relates to a fluid dispensing pump, comprising a pump body in which slides at least one piston between a rest position and an actuating position, and a turret fixed to said pump body, said turret comprising an external part extending outside said pump body, said turret comprising, on said external part, support means for receiving and maintaining a seal sealing, said support means comprising a radial shoulder, said seal being snapped onto said shoulder.
- said spinner is fixed to the upper edge of the pump body and has an internal part extending inside the pump body and defining the rest position of said at least one piston.
- said seal is annular and extends in said support means approximately perpendicular to the longitudinal central axis of the pump.
- said support means comprise a radial flange extending outwards, said flange forming a bearing surface for said seal, and said radial shoulder being offset axially relative to said flange, and forming a retaining shoulder for said seal. , said seal being assembled between said flange and said shoulder.
- the external part of the turret comprises an axial sleeve approximately parallel to the pump body, the upper edge of said sleeve being fixed to said pump body and the lower edge of said sleeve comprising said support means.
- said axial sleeve of the spinner is spaced from said pump body, so that the seal exerts no radial force on said pump body.
- the present invention also relates to a device for dispensing a fluid product, comprising a product reservoir and a pump as described above, said pump being mounted on said reservoir by a fixing element, such as a fixing ring. , said seal which is arranged in the support means of the tower being the seal ensuring the seal between the reservoir and the fixing element.
- the seal is assembled and retained by the pump spinner before the pump is assembled on the tank.
- said fixing element cooperates with the radial flange of the spinner to fix the pump on the tank, with interposition of the seal.
- FIG. 1 is a schematic cross-sectional view of a fluid dispenser device produced according to a preferred embodiment of the present invention, after assembly of the pump on the reservoir;
- FIG. 2 is a schematic cross-sectional view of the tower of the pump of Figure 1;
- FIG. 3 is an enlarged schematic view in cross section of detail A in FIG. 2.
- the distribution pump comprises a pump body 10 of generally cylindrical shape. Inside this pump body slides at least one piston 15 between a rest position, which is that shown in FIG. 1, and an actuation position, not shown, in which the piston 15 is moved to the inside the pump body.
- a rest position which is that shown in FIG. 1
- an actuation position not shown, in which the piston 15 is moved to the inside the pump body.
- the internal structure of the pump, and its operation will not be described in more detail below, since the invention does not relate directly to the operation of the pump. On the contrary, the present invention applies to any type of pump, and that shown in FIG. 1 is only an example, the scope of the present invention not being limited to this pump.
- the pump comprises a spinner 20 which is fixed to the pump body 10, and more particularly to the upper edge 11 of the pump body 10.
- This spinner 20 advantageously comprises an internal part 23 which extends inside the pump body 10 , and which can advantageously be used to define the rest position of the piston 15.
- the spinner 20 further comprises an external part 21 which extends outside the pump body and which comprises support means 30 to receive and maintain a seal 40.
- this external part 21 is advantageously produced in the form of an axial sleeve 21 which extends approximately parallel to the pump body 10, and the upper edge is fixed to the upper edge 11 of the pump body 10, while the lower edge comprises the support means 30.
- FIG. 1 is advantageously produced in the form of an axial sleeve 21 which extends approximately parallel to the pump body 10, and the upper edge is fixed to the upper edge 11 of the pump body 10, while the lower edge comprises the support means 30.
- the sleeve 21 of the spinner 20 is spaced radially with respect to the pump body, at least at the level of said support means 30, so that when the seal 40 is assembled in said support means 30, it exerts no radial force on the pump body.
- the present invention therefore makes it possible to avoid any deformation of the pump body due to the prepositioning of the neck seal 40, so that the risks of pump leakage are reduced.
- the seal 40 is generally produced in the form of an annular disc which extends approximately perpendicular to the longitudinal central axis of the pump. Indeed, this seal 40 is generally intended to seal between the upper edge of the neck of a tank 1 and a fixing element 5 used to fix the pump on said tank.
- This fixing element 5 may be a screwable ring as shown in FIG. 1, but could also be produced in the form of a snap-on ring or a crimpable capsule, or more generally in any way allowing the fixing of the pump on the tank.
- FIGS. 2 and 3 show more detailed views of the turret 20, and in particular support means 30 making it possible to pre-position the seal 40.
- these support means comprise a radial flange 33 extending outwards and with the upper side of which the fastening element 5 cooperates when the pump is fixed to the tank.
- the lower side of this radial flange 33 forms a bearing surface for the seal 40.
- a radial shoulder 31 is also provided, which is offset axially with respect to said radial flange 33, and which forms the retaining shoulder for said seal 40.
- the seal 40 is assembled between said radial flange 33 and said radial shoulder 31.
- An advantage of this method of fixing the seal 40 lies in the fact that the seal 40 no longer exerts radial force on the pump body. . It can exert such a radial force on the spinner, but this does not imply any risk of pump leakage.
- a seal 40 which is not necessarily prestressed when it is assembled in the support means 30 of the spinner. On the contrary, it could be slightly deformed to pass through above the radial shoulder 31, but then it would snap between said radial flange 33 and said shoulder 31 and could, in this position, exert no radial or axial force on the spinner. This would prevent deformation of the seal during storage or transport of the pump, and more generally before it is assembled on the tank.
- the shoulder 31 can be extended by an inclined ramp 35 which facilitates the installation, assembly, or more generally the snap-fastening of the seal 40 in said support means for the turret 20
- the manufacturer of the pump assembles all the constituent elements of the pump inside the pump body, fixes the spinner 20 on the pump body and then comes to pre-assemble the seal 40 in the support means 30 of the tourette 20.
- This sub-assembly is then delivered to the manufacturer of the fluid, which then fills the reservoir 1 with its product and then places the pump on the neck of the reservoir, the seal 40 being generally disposed on the upper edge of said reservoir.
- the pump is then fixed by the fixing element 5, which in the assembly of FIG. 1 is a screwable ring.
- the present invention therefore makes it possible to obtain in a simple and inexpensive manner the same advantages as with existing pumps, namely the delivery to the manufacturer of the fluid product of a complete pump unit which it suffices to assemble after filling the reservoir. , without the drawbacks which existed previously, namely the risks of leakage at the level of the pump body due to the compression forces exerted by the seal fitted around this pump body.
