Definitions
- Fluid product distribution device comprising a pump
- the present invention relates to a fluid product distribution device comprising a pump.
- a conventional pump comprises a pump body defining a pump chamber, with at least one piston sliding in said pump body to distribute a dose of a fluid product contained in a reservoir to which the pump is fixed.
- the pump is fixed to the neck of a tank by means of a fixing ring, and generally comprises a tourette, which is an element fixed to the pump body and which comes into contact with a neck seal provided to ensure the sealing at the level of the tank neck.
- a disadvantage of this type of pump is that it can happen that the fluid product comes into contact with the neck seal, likely in particular to absorb part of the fluid.
- the present invention aims to provide a fluid product dispensing device which does not reproduce the aforementioned drawbacks.
- the present invention aims in particular to provide a fluid product distribution device which eliminates the risks of absorption of the fluid product by a neck seal.
- the present invention also aims to provide a fluid product dispensing device which allows relatively high manufacturing tolerances.
- the present invention also aims to provide a fluid product dispensing device which is simple and inexpensive to manufacture and assemble and reliable in use, while guaranteeing perfect sealing.
- the present invention therefore relates to a fluid product distribution device comprising a pump having a pump body fixed to a neck of a reservoir containing a fluid product to be distributed, said neck comprising an upper axial edge, a compression element being arranged on said upper axial edge, said pump comprising a nozzle, said nozzle comprising a fixing part for attaching directly to said pump body, a compression part for compressing said compression element on said upper axial edge of said neck, and a fitting sleeve extending axially downwards below said compression part , said fitting sleeve coming, during the assembly of said pump on said tank, to fit into said neck of said tank, said fitting sleeve comprising at least one radial sealing profile which cooperates, after assembly, with sealed manner with said neck of said tank.
- each radial sealing profile is formed by a peripheral sealing bead.
- said fitting sleeve comprises a single radial sealing profile.
- said fitting sleeve comprises at least two radial sealing profiles, offset axially.
- said compression element is produced in the form of a neck seal.
- said compression element is formed by a deformable lip, integral with said tourette.
- said compression part is formed by a radial annular wall of said tourette.
- said tourette is a one-piece part which is fixed directly to said pump body, which is adapted to cooperate directly with said compression element to compress it on said upper axial edge of said neck, and which is adapted to cooperate directly with the interior of said pass.
- Figure 1 is a schematic sectional view of a fluid product distribution device comprising a pump
- Figures 2 to 4 are schematic sectional views, showing in detail the neck of the reservoir, the nozzle and the fixing ring, when assembling the pump on the tank, according to a first advantageous embodiment
- Figure 5 is a view similar to that of Figure 4, showing a second advantageous embodiment
- Figure 6 is a schematic view in cutaway perspective of the tourette of Figure 5
- Figure 7 is a view similar to that of Figure 4, showing a third advantageous embodiment.
- axial and radial refer to the longitudinal central axis of the device.
- top”, “bottom”, “upper” and “lower” refer to the upright position of the device shown in Figure 1.
- the device comprises a reservoir 1 provided with a neck 2, a pump 10 being assembled on said neck 2 of the reservoir 1 by means of a fixing ring 5, with the interposition of a compression element 9, useful for compensating tolerances dimensions of the parts and thus ensure reliable fixing in all circumstances.
- the compression element is a neck seal 9 placed on an upper axial edge 2' of the neck 2 of the tank 1.
- the compression element is a deformable lip 9', integral with the tower 50, and which cooperates with said upper axial edge 2'.
- the pump 10 comprises a pump body 11 provided with an upper end edge 12.
- a piston 20 slides sealingly inside of said pump body 11 at each actuation to distribute a dose of product from the reservoir 1.
- the piston 20 is integral, in particular in one piece, as shown in the drawings, with an actuating rod 30 on which is assembled a dispensing head 60 or pusher on which the user presses to activate the pump 10 .
- the pump body 11, in particular its upper end edge 12, is fixed in a spindle 50 at the level of a fixing part 51 of said spindle.
- the tourette 50 comprises a fitting sleeve 53 extending axially downwards under said compression part 52, said fitting sleeve 53 coming during assembly to fit into the axially upper part of the neck 2 of the reservoir 1 .
- the tourette 50 therefore forms a one-piece part which on the one hand is fixed directly to the pump body 11, which on the other hand cooperates directly with the compression element 9, 9' to compress it on the upper axial edge 2' of the neck 2, and which finally cooperates directly with the interior of said neck 2 of the tank 1.
- the tourette 50 is advantageously made by molding in a suitable plastic material.
- a ferrule 55 is assembled inside the pump body 11, and cooperates with the piston 20 to define the rest position thereof.
- the ferrule 55 is formed in one piece with the tourette 50.
- the fitting sleeve 53 comprises at least one radial sealing profile 54 which cooperates in a sealed manner with the neck 2 of the reservoir 1.
- sealing profiles 54 can be provided.
- this compression element 9 can be produced in the form of a neck seal, as in the examples in Figures 1 to 5.
- it can be formed by a deformable lip 9', integral with the tower 50, and which cooperates with the upper axial edge 2' of the neck 2 of the reservoir 1, as visible in Figure 7.
- An essential advantage of the present invention is that any risk of contact between the fluid product contained in the reservoir 1 and a neck seal capable of absorbing fluid is avoided by the presence of at least one radial sealing profile 54.
