Definitions

  • the present invention relates to a fluid product dispensing device comprising a spray nozzle provided with several dispensing orifices and a pump for dispensing metered quantities of fluid product. More particularly, the pump is a precompression pump in which the distribution of the fluid product is carried out at a high pressure of at least 15 bars. The present invention also relates to the method of assembling such a pump.
  • Fluid product dispensing devices comprising dispensing nozzles provided with a plurality of orifices or dispensing holes are known in particular from documents EP1878507 And WO2018100321 .
  • the diameter of the holes is generally between 8 and 20 ⁇ m.
  • the nozzle is associated with a pre-compression pump delivering the fluid product to the nozzle at a pressure less than 7 bars.
  • the nozzle is associated either with a pump whose pressure is between 2 and 7 bars, or with a pressurized valve operating with a propellant gas whose pressure is between 6 and 13 bars.
  • the present invention aims to provide a device and a pump which do not reproduce the aforementioned drawbacks.
  • the present invention aims in particular to provide a fluid product distribution device making it possible to associate a manually operated pre-compression pump delivering high pressure with a distribution nozzle provided with several distribution orifices.
  • the present invention also aims to provide a pump which delivers the fluid product at a higher pressure compared to traditional pumps.
  • the present invention also aims to provide such a pump which is simple and easy to manufacture and assemble, and reliable in its use.
  • the present invention also aims to provide such a pump which ensures total and reproducible distribution of the contents of the pump chamber at each actuation, independently of the user's actuation speed.
  • the present invention also aims to provide a method of assembling such a pump which makes it possible to improve the reliability of the pump during storage and in use, in particular by improving the integrity of the parts subjected to high pressure during of actuation.
  • said sleeve is welded to said pump body by a waterproof weld, in particular an ultrasonic weld.
  • said sealed weld is made between two respective radial flanges of said pump body and said sleeve.
  • the sealing lips of said piston, of said outlet valve element and of said inlet valve element are oriented in the direction opposite to their respective direction of insertion, so that said sealing lips are not damaged during their assembly.
  • said step of inserting said spring and said inlet valve element into said sleeve of reduced diameter is carried out before said step of inserting said piston and said outlet valve element into said sleeve.
  • the present invention also relates to a fluid product distribution device assembled by a method as described above.
  • this pump of the prior art comprises a pump body 3 in which slides a piston 1 secured to an actuating rod 2 on which the user presses to activate the pump.
  • the piston 1 slides in a pump chamber 5 defined in the pump body 3 between an inlet valve 11 and an outlet valve 12.
  • a fixing ring 4 for example crimpable, screwable or snap-on, allows the pump to be fixed on a tank.
  • the inlet valve 11, open in the pump rest position, as visible on the figure 1 , is formed by an inlet valve element 10 movable in the pump body 3 during actuation of the pump and adapted to cooperate with a part of the pump body 3 at the start of actuation of the pump to close said valve inlet valve 11.
  • Said inlet valve element 10 is made in the form of a hollow cylinder closed on one side by a bottom wall, the edge of the open end of said hollow cylinder cooperating in a sealed manner from the start of actuation of the pump with a cylinder 9 of the pump body 3 to close the inlet valve 11.
  • a spring 20 rests on the one hand on a bottom wall of the inlet valve element 10 and on the other hand on a part of the pump body 3.
  • the outlet valve 12 comprises an outlet valve element 39, advantageously formed by the lower lip of the piston 1, and is made in such a way that, when the pump is actuated, it is only opened at the end actuation of the pump to allow the expulsion of the product contained in the pump chamber.
  • This opening is made at the level of passage means formed at the level of a radial internal shoulder 40 of the pump body.
  • the objective of said passage means 40 is to form at least one fluid passage when the outlet valve element 39, which during the entire actuation stroke of the pump cooperates in a sealed manner with the pump body 3, comes at the end of the actuation stroke at said passage means 40.
  • the expulsion of the product contained in the pump chamber 5 is carried out independently of the actuation speed exerted by the user.
  • the inlet valve element 10 cooperates with the spring 20 which, when the actuation of the pump, is compressed by the movement of the inlet valve element 10 under the effect of the pressure created in the pump chamber.
  • said spring 20 of the inlet valve 11 also acts as a return spring of the pump, thus returning the piston 1 to its rest position after expulsion of the product.
  • the pump of figures 1 and 2 therefore comprises two pistons, on the one hand the piston 1, part of which defines the outlet valve, and on the other hand the inlet valve element 10 defining the inlet valve, and which when actuated acts like a piston against the external surface of cylinder 9 of pump body 3.
  • the inlet valve element 10 is also assembled around the sleeve 9 with its sealing lip which impacts the upper edge of said sleeve.
  • the inlet valve element 10 is also assembled around the sleeve 9 with its sealing lip which impacts the upper edge of said sleeve.
  • This pump of the prior art represented on the figures 1 and 2 typically delivers a pressure of around 7 bars.
  • spring 20 typically has a force F of 13 N
  • the surface S which corresponds to the external diameter of the sleeve 9 around which the valve element 10 will slide during actuation, is typically 18.8 mm 2 (the external diameter of the sleeve 9 being typically 4.9 mm).
  • the pressure P is therefore approx. 7 bars.
  • the present invention relates in particular to a precompression pump adapted to deliver a pressure of at least 15 bars, advantageously of at least 20 bars.
  • the pump according to the invention comprises a pump body 3 in which slides a piston 1 secured to an actuating rod 2 on which the user presses to activate the pump.
  • the piston 1 slides in a pump chamber 5 defined in the pump body 3 between an inlet valve 11 and an outlet valve 12.
  • a fixing ring 4 for example crimpable, screwable or snap-on, allows the pump to be fixed on a tank.
  • the side wall of the pump chamber 5 is reinforced by the insertion of a sleeve 50 into the pump body 3.
  • This sleeve 50 can be integral, for example in one piece, with the fixing ring 4.
  • This sleeve 50 thus forms a double wall in the pump chamber 5, which makes it possible to avoid deformation of the internal side wall of the pump chamber 5 because of the high pressure created by the pump during actuation.
  • This sleeve 50 includes the radial shoulder which defines the outlet valve 40.
  • a waterproof weld 55 is provided, for example by ultrasound, preferably between two radial flanges respectively of said pump body 3 and of said fixing ring 4 which incorporates the sleeve 50.
  • the sleeve 9, which cooperates with the inlet valve element 10 extends axially the pump body 3 downwards in the orientation of the figures 6 to 14 and contains said inlet valve element 10 and said spring 20.
  • the inlet valve element 10 is solid and has peripheral sealing lips which extend radially outwards. In the rest position, visible in particular on the Figure 6 , these sealing lips do not cooperate in a sealed manner with the sleeve 9, so that the inlet valve 11 is open.
  • the valve element 10 will slide axially in the sleeve 9 by compressing the spring 20. This sliding is carried out in a sealed manner, the sealing lips of the valve element 10 cooperating in a sealed manner with the sleeve 9.
  • the sleeve 9 has a reduced diameter compared to the pump body 3. It advantageously includes external reinforcing ribs 90, visible in particular on the figures 5 And 7 to 9 .
  • This implementation of the sleeve 9 makes it possible to reduce its radial dimensions, with typically an internal diameter less than the external diameter of the sleeve 9 of the pump of the figure 1 . So for example, the sleeve 9 of the pump of the Figure 6 could have a diameter less than 4.2 mm, advantageously less than 4 mm, preferably 3.9 mm.
  • the piston 1 and the outlet valve element 39 could be made in one single piece, but preferably, as shown in the figures 3 And 6 to 14 , the outlet valve element 39 is formed by a separate part which is fixed in the piston 1. This fixing can be done by force-fit, snap-fit, screwing, or any other suitable fastening.
  • the sealing lips of the piston 1 and the outlet valve element 39 are oriented in the same direction, downwards in the position of the Figure 6 .
  • One of the characteristics of the pump according to the invention is the assembly of the piston 1 and the outlet valve element 39 in the sleeve 50. Unlike the pump of figures 1 and 2 , this assembly is done from below, as visible on the figures 12 and 13 . Thus, the sealing lips are not weakened by this assembly, said lips being oriented in the opposite direction to the direction of assembly. In this way, the elastic deformation of the sealing lips is not carried out by frontal contact of the radially external surface of the lips against the sleeve 50 of the pump chamber 5, but on the contrary, the lips are gradually deformed radially towards the inside, so that the sealing surfaces are not subject to any sudden stress which could alter their sealing capacity.
  • the inlet valve element 10 has sealing lips oriented in the opposite direction to the sealing lips of the piston 1 and the outlet valve element 39. As visible in the Figure 14 , said inlet valve element 10 is assembled in the sleeve 9 of the pump body from above. In this way, its sealing lips are also not damaged during assembly.
  • the pump according to the invention therefore significantly improves the sealing capacities of the various sealed parts, namely the piston 1, the outlet valve element 39 and the inlet valve element 10.
  • a spring having a greater force typically at least 20 N, advantageously 25 N.
  • the present invention makes it possible to provide a pre-compression pump of standard type but capable of distributing the fluid product at a pressure of at least 15 bars, advantageously around 20 bars, which is much superior to traditional standard pumps and even superior to valves operating with propellant gas.
  • the actuation force of such a pump with a 25 N spring and the surface S of 12 mm 2 is less than 60 N, advantageously around 50 N, which remains acceptable.
  • the step of inserting the spring 20 and the inlet valve element 10 into the sleeve 9 of reduced diameter can be carried out before the step of inserting the piston 1 and the outlet valve element 39 in the sleeve 50.
  • the inlet valve 11 closes, by sealed cooperation between the lips of the inlet valve element 10 and the internal cylindrical surface of the sleeve 9, while the outlet valve 12 remains closed.
  • the spring 20 is compressed under the effect of the inlet valve element 10 which slides in the sleeve 9.
  • the sleeve 9 having a reduced diameter compared to the sleeve 50 disposed in the pump body 3, and the fluid contained in the pump chamber 5 being incompressible, this compression of the spring 20 occurs relatively easily, despite the high force of said spring 20.
  • FIG. 9 illustrates the actuated position, with the outlet valve open and therefore the contents of the pump chamber 5 which is expelled under the effect of the spring 20 which relaxes.
  • the fluid product is then expelled with a pressure of at least 15 bars, advantageously at least 20 bars.
  • THE figures 10 and 11 show a variant embodiment, in which a second spring 80 is provided to assist the user in his actuation effort, in order to reduce it.
  • the second spring 80 is advantageously arranged around the piston 1 to urge it towards its actuated position.
  • the second spring 80 therefore acts against the spring 20, and consequently its force must be less than that of the spring 20.
  • the piston 1 can be secured to an external sleeve 2' assembled around the actuating rod 2, itself secured to the outlet valve element 39.
  • This implementation could also be adapted to the variant of the figures 6 to 9 .
  • the present invention also relates to a fluid product distribution device comprising a pump as described above, associated with a spray nozzle comprising a plurality of distribution orifices.
  • micro-hole nozzle such as that described in the document WO2018100321
  • the use of a micro-hole nozzle may depending on the design of the nozzle, and in particular if the micro-holes have a diameter less than 5 ⁇ m, or even less than 2 ⁇ m, require a fluid arriving with high pressure, typically greater than 15 bars.
  • the present invention makes it possible to guarantee a pressure of at least 15 bars, advantageously at least 20 bars, without using propellant gas.
  • the device comprises a body 101 containing a reservoir 100, on which a pump as described above is mounted, by means of the fixing ring 4.
  • the tank 100 is preferably without air intake.
  • a deformable pocket 105 is fixed inside said reservoir 100, said pocket containing the fluid product and deforming as the doses are distributed.
  • the filling of the bag can be carried out under vacuum. This implementation guarantees the delivery of almost all of the product contained in the bag, it allows actuation of the device in any orientation, and it avoids any risk of contamination of the fluid product contained in the bag.
  • a follower piston could also be used in the reservoir 100.
  • a micro-hole nozzle 200 is arranged in a distribution tip 110 fixed to the body 101.
  • This distribution tip 110 can be for example a mouthpiece.
  • the fluid expelled by the pump strikes a plate pierced with a plurality of micro-holes, which generates the spray of the fluid.
  • the micro-holes of the nozzle 200 have a diameter of less than 5 ⁇ m, preferably less than 2 ⁇ m.
  • a filter 150 is interposed between the outlet of the pump and the nozzle 200.
  • This filter serves to filter the impurities which could be transported by the fluid when it passes through the various plastic parts. Indeed, there is always a risk that particles are generated during the manufacturing and assembly processes, with the risk of blocking the micro-holes in the nozzle.
  • the body 101 comprises a lateral actuating arm 160, which makes it possible to actuate the pump by lateral actuation.
