Definitions

  • the present invention relates to a two-phase distribution device, that is to say for simultaneously dispensing a fluid and a gas, generally of the air.
  • This kind of dispensing device is generally mounted on a tank containing the fluid to be dispensed.
  • Such a device can be used for two different applications: in a first application, this kind of distributor is used as a foam pump for dispensing a fluid product under foam form, i.e. mixed with fine air bubbles.
  • the device can be used to dispense the fluid in the form of a jet of finely sprayed droplets entrained by the air flow.
  • the delivery device has a design identical incorporating a fluid pump and an air pump.
  • the dispensing device further comprises a foaming chamber, then that in the case of application in the form of a sprayer, the dispensing device is generally equipped with a nozzle at the outlet allowing the dispersion of the fluid product into fine droplets.
  • WO 95/30490 describes a two-phase distribution device, in which a free piston is mounted sliding on an actuating rod, the free piston also being slidably mounted in a pump body so as to delimit the pump chamber.
  • the free piston defines with the actuating rod the top valve of the fluid pump as well as the upper valve of the air chamber.
  • the fluid product under pressure flows inside an internal conduit formed at inside the actuating rod.
  • pressurized air flows through a separate duct.
  • the two conduits of fluid and air come together at a spray nozzle which allows distribute the fluid in the form of a jet of fine droplets.
  • Another pump described in document EP-0 613 728 which discloses the preamble of claim 1, comprises a check valve fluid outlet located at the upper end of the actuating rod and a air pump outlet valve communicating with the upper end of the rod actuation by an air passage which extends around the actuation rod. The also, the mixing of the air and the fluid product is carried out only at the exit of the rod actuation so that the mixing volume is restricted.
  • the present invention therefore aims to define a dispensing device biphasic, in particular a foam pump but not only, in which the mixing of fluid and air takes place in a large volume allowing a good homogeneity of the mixture.
  • the present invention provides a product distribution device fluid according to claim 1.
  • the outlet valve of the air pump is formed by the piston free. Therefore, there is only one piece that performs the dual function of organ mobile outlet valve.
  • the actuating rod forms a valve seat for the air pump outlet valve.
  • the free piston allows on the one hand to isolate the two chambers one from the other, and on the other hand forms the movable valve member for the two outlet valves of the two chambers.
  • the actuating rod defines, at the level of the free piston, several radial channels surrounded by an internal wall of the free piston, together defining a part of said duct common. It is thus possible to form the part of the actuating rod located at the level of the free piston so as to have a substantially shaped cross section star with three, four or five branches depending on the number of radial channels that one wants to train.
  • the sum of the cross sections of the different radial channels is considerably larger than that of a conventional internal channel extending to inside the actuating rod. Therefore, the volume geometry of mixing is very complex and therefore generates a lot of turbulence.
  • the common duct has a large section, there is only a pressure drop very low at the outlet of the valves, which allows actuation of the particularly soft and supple distribution.
  • the free piston comprises at least one lip seal in leaktight sliding contact with the body and a sealing lip in sealed sliding contact with the actuating rod.
  • the rod actuator includes a socket defining an internal sliding wall against which the sealing lip is in leaktight sliding contact. It is advantageous for the piston to penetrate inside the sleeve with its sealing lip: In this way, the sealing lip is strongly pressed against the internal wall of sliding by the fluid under pressure flowing through the common conduit at the outlet of the valve. This avoids any risk of leakage at the contact of sliding of the piston lip in the rod socket.
  • the wall internal sliding sleeve is formed with at least one rupture profile seal at which the piston sealing lip is no longer in contact watertight so as to form an air passage towards the common duct.
  • the sealing rupture profile is in the form of a obviously or a groove made in the internal wall of the sleeve.
  • the sealing rupture profile is in the form of a flat surface pan creating a defect in circularity in the internal wall of the sleeve.
  • the common conduit communicates downstream with a chamber for forming foam.
  • the conduit common communicates downstream with an outlet nozzle.
  • the dispensing device used to illustrate the present invention is a foam pump for dispensing a fluid product mixed with air from so as to form a foam at the outlet of the dispensing device.
  • the fluid contained in a reservoir (not shown) contains an agent suitable foaming agent, in contact with air, to expand so as to trap fine bubbles air inside the fluid. A foam is thus obtained at the outlet of the distributor.
  • the present invention could also have been illustrated by means of a two-phase pump for distributing a spray of fine droplets of fluid product.
  • the outlet of the distribution device is generally equipped a spray nozzle.
  • the dispensing device comprises a fluid pump designated as a whole by the reference numeral 1 and an air pump defining an air chamber 54 of variable volume.
  • the device is provided with a pusher 4 on which is pressed, at a bearing surface 41, to activate the fluid pump and the air pump simultaneously.
  • the device distribution further comprises an outer covering 52 in leaktight engagement with a internal fixing ring 51 used for fixing the device to the neck of a tank (not shown) containing the fluid product to be dispensed.
  • Inner tube 54 is located substantially around the fluid pump 1 with a wall of the ring attachment 51 serving as the bottom for the air chamber 54, the internal wall of the covering 52 serving as a sealed sliding wall for an air piston 48 of substantially shaped shape annular mounted inside the pusher 4.
  • the pusher 4 defines at its upper part the bearing surface 41 to which a peripheral skirt 44 is connected, here of ogival shape, which ends in a collar 45 which projects outwards.
  • the pusher 4 defines a sleeve 46 whose free lower end serves when connected to an actuating rod 2 which is an integral part of the fluid product 1.
  • the sleeve 46 internally defines a conduit which extends towards the top by an outlet channel 42 opening to the outside through an outlet orifice 43.
  • the sleeve 46 receives inside an insert defining a foam-forming chamber 47.
  • Chamber 47 includes a low inlet and a high outlet, both with a filter for foaming.
  • the foaming chamber 47 can be provided under the shape of a separate plastic part forcibly inserted into the sleeve 46 of the pusher 4 which can be formed in one piece.
  • the air piston 48 extends in an annular shape stepped around the sleeve 46 with which it is in sealed contact at an annular sealing lip 481. This lip 481 provides a static seal at the sleeve 46. On its periphery outside, the air piston 48 defines a lip 482 intended to come into contact with sealed sliding with the internal wall of the covering 52.
  • the external collar 45 pusher 4 is in contact, with its lower annular surface, with the periphery outside of the air piston 48 substantially at the level of the dynamic sealing lip 482.
  • the dispensing device is shown in the rest position, in which the outer flange 45 of the pusher 4 is in abutment against an inner flap 521 of the casing 52 used to fix the top dead center of the air pump.
  • the covering 52 is in leaktight engagement with the ring of fixing 51 which forms the bottom of the air chamber 54.
  • the fixing ring 51 is formed for this purpose with an outer ring 513 in tight contact with the inner wall of the covering 52 and an internal screw ring 512 formed with an internal thread intended to cooperate with an external thread formed on the neck of the container (not shown). he this is a screw fixing, but of course other fixing techniques can be imagined without departing from the scope of the invention.
  • the outer ring 513 and the inner ring 512 are connected and extend inward by an internal annular flange 511 defining a central opening at through which the fluid pump 1 passes.
  • This internal flange 511 engages with an external fixing flange 142 which is an integral part of the pump fluid product 1.
  • the outer flange 511 presses the collar 142 on the end upper neck with possible interposition of a seal 17. From this way, the dispensing device is fixed to a fluid reservoir.
  • the fixing ring 51 forms substantially at the level of the junction of the outer ring 513 and the inner ring 512 several conduits air intake 514 which are selectively closed by a flexible washer 515 which is pressed against the outlet of the conduits 514.
  • the washer 515 is pressed by the pressure on the conduits 514 and seal them tightly.
  • air can be drawn in through ducts 514 by lifting the washer 515 slightly.
  • the washer 515 in combination with the conduits 514 forms the air intake valve for the air chamber 54.
  • This fluid pump 1 comprises a pump body 10 in the form general cylindrical provided at its lower end with an inlet 11 on which can be connected to a dip tube. Above the inlet 11, the pump body 10 defines a valve seat 120 for a ball 12 serving as a low valve member. Ball 12 is advantageously confined in a limited space defined by an insert 121 on which comes to bear on the lower end of a return spring 15. At its end upper, the pump body 10 is provided with an annular reinforcement 13, projecting towards the outside, snapped into a housing formed by a spindle 114 which form on the outside the retaining flange 142 intended to come into engagement between the flange 511 of the fixing ring 51 and the upper end of the tank neck (not shown) with the possible interposition of a seal 17.
  • An air return passage can be formed in the peripheral reinforcement 13 to allow air to enter the reservoir from outside as fluid is distributed through the pump 1.
  • the turret 114 defines inside the body 10 a ferrule 141 which makes it possible to limit the stroke of pump 1 and fix its rest position.
  • the fluid pump 1 is conventionally provided with a rod actuator 2 at the lower end of which the other end of the return spring 15 so as to urge the actuating rod 2 in its position rest shown in Figure 1.
  • the actuating rod 2 is provided with a free piston 3 which can move on the actuating rod 2 over a limited distance.
  • the numerical references relating to the free piston 3 are visible in FIG. 2a.
  • the piston free 3 is therefore slidably mounted on the actuating rod 2 and, on the other hand, it slides inside the pump body 10 with seal.
  • the actuating rod 2 is here formed of a lower part 21 and a part upper 22 connected to each other for example by interlocking force.
  • the part upper 22 defines a flow passage 221 at its end upper which is inserted inside the sleeve 46 defined by the pusher 4.
  • the upper part 22 defines a substantially cylindrical skirt 222 defining at its lower end a waterproof sliding bush 223.
  • the lower part 21 is inserted into the upper part 22 so that the substantially cylindrical skirt 222 partially surrounds the lower part 21.
  • the assembly of the two lower parts 21 and upper 22 defines between them a conduit 23 which communicates with the flow passage 221 formed at the end upper part of upper part 22.
  • Lower part 21 defines a large part from its height several radial channels 211 which extend up to near the lower end of the lower part 21 where it forms a plate 213 in which is defined an annular groove 212 serving as outlet valve seat. This groove 212 is formed on the upper surface of the tray 213 while the lower surface of the tray 213 receives the upper end of the return spring 15.
  • the free piston 3 is mounted on the lower part 21 of the actuating rod 2.
  • the piston 3 includes an inner sleeve 33 which internally defines a wall internal 87 which surrounds the lower part 21 formed with the radial channels 211.
  • the lower end of the cuff 33 forms a high valve member 332 adapted to come into tight contact in the annular groove 212 formed by the lower part of the actuating rod as can be seen in Figure 1 in the rest position.
  • the cuff 33 defines a sealed sliding lip 331 adapted to come into tight sliding contact with the internal wall 224 formed by the sliding bush 223 of the actuating rod 2.
  • the piston 3 in the rest position, the sleeve 33 of the piston 3 rests tightly in the valve seat groove 212 and against the internal wall 224 of the sealed sliding sleeve 223.
  • the piston 3 includes an outer ring 31 connected to the cuff 33 by a flange connection 32.
  • the outer ring 31 defines at each of its ends a lip 311 and 312 in tight sliding contact against the inner wall of the pump body 10.
  • the sealing lip upper 311 of piston 3 abuts against the lower end of ferrule 141 of so as to fix the top dead center of the pump 1.
  • this fluid pump 1 takes place in the manner following: when push button 4 is pressed, the actuating rod is pushed into the pump body 10 so that the pump chamber decreases in volume. For compensate for this reduction in volume, the free piston 3 which is then no longer in contact stop with the ferrule 141 moves relative to the actuating rod 2 so open the top valve to create an outlet passage for the flowing fluid then between the free piston 3 and the lower part 21 of the actuating rod 2. The product then flows into a conduit 23. From there it flows through passage 221 then through the chamber 47 and finally the outlet channel 42 which leads to 43 on outside.
  • the piston 3 and more particularly with respect to the internal wall 87, partially defines the external wall of the conduit making it possible to connect the outlet of the high valve at passage 221 leading outwards. Since the internal diameter of the cuff 33 is relatively large compared to that of a internal actuator rod conduit of a conventional distributor, a large passage section which therefore defines a large internal volume and which on the other hand only induces a small pressure drop. As soon as you leave the high volume valve in which the product can be mixed foaming with air from the air pump.
  • the air pump outlet valve is defined by the cuff 33 of the piston 3 at its contact with the sliding bush 223.
  • the air which is compressed in the pump chamber 54 finds a defined outlet passage between the actuating rod 2 and the ferrule 141 as can be seen in FIG. 2d. More specifically, the air first escapes between the lower part of the sleeve 46 of pusher 4 and ferrule 141 of turner 14. Then the air finds a passage between the upper part 21 more precisely the skirt 22, and the ferrule 141. More bottom, the air flows between the bush 223 and the internal wall of the pump body then between the ring and piston. The air flow passage is indicated by bold arrows in Figure 2d.
  • the wall internal 224 of the socket 223 is formed with a profile 225 making it possible to interrupt the sealed contact of the lip 331 with the wall 224.
  • This sealing interruption profile 225 may for example be in the form of grooves or grooves at the level of which the lip 331 cannot establish a tight contact.
  • the sealing interruption profile 225 can be present in the form of flat surface sections which interrupts the cylindricity of the wall 224 so that at the junction of the sides with the cylinder segments, edges are created at which the lip 331 cannot come into contact waterproof.
  • the particular form of the interrupt profile (s) sealing 225 does not limit the present invention to the extent that air can find a flow passage at this level when the dispensing device is in position actuated shown in Figure 2a.
  • the air which flows beyond the top valve formed by the lip sealing 331 in sliding contact with the wall 224 opens into the same conduit that that in which the fluid flows.
  • Pressurized air and product pressurized fluid therefore flow into a common conduit 23 formed between the piston 3 and the actuating rod 2 in its lower part then between the lower part 21 and the upper part 22 of the actuating rod 2.
  • the pressurized air is therefore injected into the pump 1 near the top valve of the fluid pump so that the air and foaming fluid are mixed immediately at the outlet of the respective high valves of the fluid pump and the air pump.
  • the principle of the present invention is based on the fact that the piston is used free to form the two outlet valves of the fluid and air pumps for lead into a common conduit 23, which also has a volume of mixture important and complex.
  • the fluid pump is used to form a mixing chamber, so that at the outlet of the actuating rod, the fluid product is already in the form of foam.
  • the foaming chamber located in the pusher further improves the quality of the foam. So we have in the present invention of a double stage of foam formation. In the pumps conventional foam, there is at most a single foaming chamber in which air is injected.
  • This provides a particularly effective distribution device for the distribution of a foam, but which can of course be used as a dispenser in the form of a spray of fluid sprayed product.
