Definitions

  • the present invention relates to a pump for improved fluid product distribution and a device fluid dispensing system comprising such pump. More particularly, the present invention relates to a fluid dispensing pump incorporating filtration and / or treatment means of venting air.
  • the first one solution is to use an airless system, it's up to say without air intake, with in this case a reservoir of product that decreases in volume at each distribution for compensate for the depression created by the expulsion of a quantity of product determined. This can be done by example using a flexible pouch emptying gradually or a follower piston disposed in the tank.
  • the second solution is to treat, filter the incoming air, after each product distribution. To do this, we use advantageously filter elements arranged in the venting air passage from the pump or device distribution.
  • document EP-0 189 549 discloses arrange a filter against the vertical side wall of the pump body incorporating a vent hole.

  • the subject of the present invention is therefore a pump of fluid dispensing comprising a body of pump, a piston sliding in a sealed manner in said pump body between a rest position and a position of distribution, and a fixing ring for assembling said pump on a tank, the upper edge of the pump body being fixed in said fixing ring, a seal ring being disposed between said pump body and said fixing ring, said pump further comprising a vent air passage between the reservoir and atmosphere, characterized in that an element of filtering and / or venting air treatment is provided in said vent air passage, said element filter being disposed between said upper edge of the pump body and said fixing ring.
  • said vent air passage is open in all pump positions.
  • said annular seal forms the element filtration, said seal being permeable to air and fluid-tight fluid dispensed by said pump.
  • the pump comprises a ferrule mounted on the upper edge of the pump body between said upper edge on the one hand, and said seal ring on the other hand, said ferrule extending to inside said pump body to cooperate with said piston in the rest position, the filter element being disposed between the upper edge of the pump body and said ferrule.
  • the upper edge of the pump body has a through bore defining a portion of the venting air passage, said filter element being disposed between said upper edge of the pump body and said ferrule, completely covering said bore crossing.
  • said filter element comprises means of passage to define a part of passage of air between the ferrule and the annular seal.
  • said venting air passage is defined between the ferrule and said pump body so that the ferrule closes said air passage in the rest position of the pump, said air passage being open when said piston is moves to its dispensing position.

  • the pump body 10 is usually assembled on the neck of a tank 1 to using a fixing ring 5, which can be any other, in particular snap-in, screwable, or crimp.
  • the seal between the pump and the ring fixing 5 is carried out by means of an annular seal 100, 200 and the seal between the fixing ring 5 and the tank 1 is made by means of a collar 300.
  • a pump chamber 30 is defined between an inlet valve 40, 41 and a check valve outlet 50, 51, so that the pump shown on the figures is a pre-compression pump.
  • a dispensing head no shown
  • the actuating rod 21 moves the piston 20 in a sealed manner in the pump body 10.
  • This displacement causes the closure of the inlet flap 40 so the product volume is defined inside the pump chamber 30.
  • the outlet valve 50 opens by the pressure created at inside the pump chamber 30, so that said product dose is expelled through the canal of expulsion 6.

  • This air passage venting first passes between the actuating rod 21 and the upper end of ferrule 60. It goes down the along the inner wall of ferrule 60 to the lower end of it, where it is closed by the piston 20 in the rest position.
  • venting air passage 80 is open at this location and it extends between the pump body 10 and the outside of ferrule 60 to level of the upper edge 11 of the pump body 10. Next, it passes between the outside of the pump body 10 and the fixing ring 5 and penetrates inside the tank (not shown in Figure 1).
