- a fixing ring is generally provided for fixing this pump to a reservoir containing the fluid product.
- a dip tube can also be associated with the pump to extend to the bottom of the tank and allow the distribution of all of the product contained therein.
- This type of pump comprises a relatively large number of component parts, which makes its manufacture and its assembly relatively complicated and expensive.
- Another problem which can arise, in particular when the fluid product is a pharmaceutical product, is that the product is generally in contact with the springs of the pump, these being generally metallic. Depending on the pharmaceutical product under consideration, this type of contact with a metallic product can be harmful and cause product alteration.
- the object of the present invention is to provide a fluid dispensing pump which does not have the abovementioned drawbacks. More particularly, the present invention aims to provide a fluid dispensing pump which is simple and inexpensive to manufacture and assemble. The present invention aims in particular to provide a fluid dispensing pump which is made up of a minimum number of component parts.
- the present invention also aims to provide a fluid dispenser pump, which eliminates any risk of alteration of the fluid product dispensed by said pump, in particular by eliminating any contact with metal parts.
- the present invention therefore relates to a fluid dispenser pump comprising a pump body, a pump chamber, at least one piston sliding in said pump chamber for dispensing the fluid product, a dispensing orifice, and a shutter.
- the shutter cooperating with said dispensing orifice, said shutter being displaceable and / or deformable between a position for closing the dispensing orifice and a position for opening the dispensing orifice, said shutter being resiliently biased towards its position of obturation, the pump comprising a single elastic element, such as a spring, adapted to return said at least one piston to its rest position after actuation and to urge said obturator to its obturation position, and said pump body being produced of a single piece with said shutter.
- said spring is out of any contact with the fluid product.
- the pump includes a fixing ring adapted to fix said pump on a tank.
- said fixing ring is made in one piece with a dip tube intended to extend into a reservoir.
- said fixing ring is made in one piece with a seat of the inlet valve of the pump chamber.
- the pump comprises a dispensing head comprising the dispensing orifice.
- said pump body is arranged inside said dispensing head.
- said dispensing head is connected, in particular snapped-in, in a non-removable manner on said fixing ring, said dispensing head and said fixing ring forming a stop to define the rest position of the pump.
- said piston is made in one piece with said fixing ring.
- said pump consists of only four parts comprising the part (A) forming a dispensing head, the part (B) forming the pump body and obturator, the part (C) forming a spring, and the part (D) forming a piston, fixing ring and dip tube.
- the part (D) forming a piston fixing ring and dip tube also forms the seat of an inlet valve of the pump chamber, cooperating with a valve element.
- the valve element is integral with the part (B) forming the pump body and the shutter.
- the valve element is a separate part (E) such as a ball.
- said pump chamber is arranged immediately upstream of said dispensing orifice, said shutter forming an outlet valve of said pump chamber.
- the present invention also relates to a device for dispensing a fluid product, comprising a reservoir and a pump as described above.
- the pump is fixed, in particular snapped on, on the tank with the interposition of a seal.
- FIG. 1 is a schematic cross section of a fluid dispenser device comprising a fluid dispenser pump produced according to an advantageous embodiment of the present invention, in the pump rest position;
- - Figure 2 is a view similar to that of Figure 1 at the end of actuation of the pump;
- - Figure 3 is a schematic cross-sectional view of a fluid dispenser device comprising a fluid dispenser pump according to another advantageous embodiment of the present invention, in the pump rest position;
- - Figure 4 is a view similar to that of Figure 3, at the end of actuation of the pump;
- - Figure 5 is a schematic exploded perspective view of the fluid dispenser device shown in Figures 3 and 4.
- the dispensing pump comprises a pump body 10 in which slides at least a first piston 30 , 72. Said at least one piston 30, 72 slides in a pump chamber 20 to dispense a dose of fluid product through a dispensing orifice 45, each time the pump is actuated.
- Said pump chamber 20 preferably comprises an inlet valve 70.
- the dispensing orifice 45 is provided with a shutter 38 which is movable and / or deformable between a position of closure of this dispensing orifice 45 and an open position thereof, said shutter 38 being resiliently urged towards its closed position.
- the pump comprises a single elastic element 50, such as a spring, which is adapted both to return the piston 30, 72 to its rest position after actuation and to urge the shutter 38 to its closed position.
- this spring is disposed out of any contact with the fluid product, which avoids any risk of contamination, especially when this spring is metallic.
- the pump comprises a dispensing head 40 which incorporates the dispensing orifice 45.
- the pump chamber 20 is disposed at least partially in said dispensing head 40, directly upstream of said dispensing orifice 45. L shutter 38 then forms the outlet valve of this pump chamber.
- the pump can be fixed to a reservoir 60 containing the fluid by means of a fixing ring 15, which can be of any desired type, for example screwable, snap-on or crimpable.
- the pump is assembled on the reservoir 60 by means of said fixing ring 15 with the interposition of a seal 65 between these two elements.
- Figures 1 and 2 show an advantageous reahsation mode of the present invention.
- the pump body 10 is produced in a single piece with the shutter 38, and the piston 72 therefore slides inside said shutter 38.
- the pump body 10 is therefore placed inside said shutter head 40.
- the fixing element 15 is itself made in one piece with the piston 72 and the seat of the inlet valve 71.
- the dip tube 18 is in this example reported, but it could of course also be made in one piece with said fixing ring 15.
- the return spring 50 is directly in contact with a second piston 34 integral with the shutter 38, being arranged around said tubular element forming the piston 72 and the valve seat 71 of the valve inlet 70 of the pump chamber 20.
- the valve element 75 is in this example produced in the form of an added element, in particular a ball 75 cooperating with said valve seat 71.
- the part forming the pump body 10 and shutter 3 8 comprises in this embodiment an opening 32 adapted to cooperate with the piston 72 to allow priming.
- the dispensing orifice 45 includes a spray profile (not shown) which can for example be arranged in an axial sleeve 150 of the head 40 in which said shutter 38 slides.
- the priming of this pump is produced by the opening 32 provided in the shutter 38 which cooperates with the piston 72.
- Figures 3 and 4 show another advantageous reahsation mode of the present invention. This differs from the embodiment shown in FIGS. 1 and 2 in that the dip tube 18 is produced in a single piece with the fixing element 15 and in that the part forming the pump body 10 and the shutter 38 comprises a third piston 35 also sliding in the head
- a passage 33 is provided at this second part of the pump chamber 23 to allow a backflow of part of the product contained in the pump chamber 20 under certain conditions.
- the pressure rising rapidly _. in the pump chamber causes excessive movement of this valve in the axial sleeve 150 provided in the bottom of the head 40.
- the head 40 has passage means cooperating with the third piston 35 for, after a movement predetermined axial of said shutter 38, open the connection between the first part of pump chamber 21 and the second part of chamber 23, thus causing an overpressure in this second part of pump chamber 23, and therefore a backflow of part of the product through the passage 33 towards the radial passage 74 then the dip tube 18 in the direction of the reservoir 60.
- the figures represent various alternative embodiments, but other implementations are also possible.
- the pump body could be made in one piece with the dispensing head, the piston then sliding directly in this head.
- a particular advantage of the present invention is that it makes it possible to produce a pump with a minimum of constituent parts.
- FIG. 5 it can be seen that the pumps of FIGS.
- 1 to 4 can be produced with only four components, namely the part A forming the dispensing head 40, the part B forming the pump body 10 and the shutter. 38, the part C forming a spring 50, and the part D forming a piston 72, fixing ring 15 and dip tube 18.
- the valve element 75 of the inlet valve 70 of the pump chamber 20 is produced under the shape of a separate part E (for example a ball), it can be considered that the pump comprises a fifth part.
- the pump is then assembled on the reservoir 60 with the interposition of a seal 65, and it therefore appears clearly that the number of parts of the pump according to the invention is lower in comparison with the pumps of the prior art , which simplifies the manufacture and assembly of this pump, and therefore makes it less expensive.
