Definitions

  • the object of the present invention is to overcome the various drawbacks stated above, by means of a device making it possible to purge the residual air present in the reservoir, and this while protecting the purge ring as soon as it leaves the mold and until it is mounted in the tank to avoid any risk of subsequent leakage.
  • This reservoir 6 can be flexible or rigid, contain a piston 8 (or another system) or not to follow the variability of the volume of product 7.
  • the figure 4 shows a second possible configuration of the air purge device according to the invention. It still consists of a purge ring 1, and a protective part consisting in this case of a piston 8.
  • This device is intended to be no longer placed on a distributor head, therefore in the upper part of a distributor, but in the bottom of the reservoir 6 of the distributor, therefore in the lower part of a distributor.
  • the piston 8 moves from the bottom to the top of the reservoir 6 in order to reduce the internal volume of the reservoir 6 as the consumer takes product 7. It ensures by sliding the static and dynamic seal with the internal wall of the tank 6.
  • a first sleeve 85 extends from the upper surface of the disc 81, in the direction of the ring 1, and accommodates the sleeve 13 of the ring 1.
  • a second sleeve 83 extends from the lower surface of the disc 81, in the direction of the ring. bottom of the reservoir 6 when the piston 8 is mounted in the reservoir 6.
  • the orifice opens out into the two sleeves 83,85.
  • the diameter of the first sleeve 85 is less than the diameter of the second sleeve 83.
  • the end piece 16 of the sleeve 13 of the ring 1 is retained by this shoulder 80 after it snaps into the second sleeve 83 of the piston 8.
  • the piston 8 comprises a second peripheral skirt 82 connected to the outer periphery of the disc 81 and extending in the direction of the bottom of the reservoir 6 when the piston 8 is mounted in the reservoir 6.
  • the free ends of the two skirts 82,84 consist of sealing lips 89,88, the function of which is to seal the reservoir 6 when the dispenser is used.
  • These lips 89,88 are also fragile, just like the lip 12 of the ring 1.
  • the purge ring 1 and piston 8 assembly is fixed in a bottom part 9 which will be stored. in bulk then packaged. This bottom part 9 protects the lips 89,88 of the piston 8, as can be seen in figures 5a and 5b .
  • the bottom part 9, purge ring 1 and piston 8 assembly is called a sealing device because it enables a reservoir 6 which has no bottom to be closed. It is this type of reservoir 6 which will be used to accommodate the purge ring 1 and piston 8 assembly according to the invention.
  • the tank 6 in figure 6a (variant a) comprises an interlocking zone 61 located at a distance from its open end 62, so that the long section 92a of the bottom part 9 according to the figure 5a come and fit into it.
  • FIGS 7a and 7b The bottom part 9 is then positioned above the reservoir 6 and centered on the reservoir 6, so that the lip 88 of the first skirt 84 of the piston 8 comes into contact with the internal wall of the reservoir 6 so that to seal it. As the bottom part 9 moves closer to the reservoir 6, the air pressure contained in the volume A increases. This volume A corresponds to the volume of air included in the reservoir 6 between the product 7 and the ring 1.
  • the piston 8 is therefore movable relative to the bottom part 9 between an initial extended position visible to the figures 5a to 8b , and a retracted final position visible to figures 9a to 9b .
  • Ring 1 remains fixed relative to piston 8.
  • the figures 10 to 12 present a third possible configuration of the purge device.
  • the bottom part 9, the piston 8 and the ring 1 are identical to the parts described according to figures 5a to 9b (two variants always possible), with a few details as explained below.
  • the piston 8 comprises a single sleeve 83 developing in the direction of the bottom part 9, and coming to fit into the orifice of the bottom part 9.
  • the bottom part 9 continues its approach, until it fits over the reservoir 6.
  • the lip 89 of the second skirt 82 of the piston 8 finally comes into contact with the internal wall of the reservoir 6 so as to finalize the seal .
  • the volume of air A is always expelled into the chamber B via the ribs 87 formed in the skirt 84 of the piston 8, then escapes to the outside via the ribs 10 formed in the sleeve 13 of the ring 1.
  • the sleeve 13 extends from the outer periphery of the cap 11 in the direction of the piston 8, while the lip 12 extends from the periphery of the internal orifice 14 of the cap 11 in the direction of the piston 8.
  • the lip 12 still comes into contact with an internal wall of the piston 8, but it is now the wall of the first sleeve 85.
  • the lip 12 surrounds the first sleeve 85, and comes into contact with the wall of the sleeve 85.
  • the sleeve 13 comes into contact with the internal wall of the first skirt 84 of the piston 8 in a sealed manner.
