Definitions

  • DE-A-26 15 668 which has served as the basis for the preamble of claim 1, relates to a method of manufacturing foam using a distributor comprising a valve and an additional gas outlet opening into a chamber placed before the valve and not in the valve.
  • the additional gas intake is used to make the foam in the dispenser.
  • the product to be dispensed leaves as a foam from the dispensing valve.
  • GB-A-2 184 789 describes a device for dispensing foam using a liquefied propellant comprising a valve and a nozzle.
  • the foam is produced at the outlet of the valve and the nozzle is used to modify the consistency of the foam.
  • the Applicant has found that by providing the distributor with a nozzle for transforming a spray into foam with dimensional characteristics as described below, said distributor is adapted to supply foam under good conditions.
  • the present invention relates to a pressurized foam distributor containing a foaming liquid pressurized by a non-liquefiable compressed gas equipped with a distribution valve and an additional gas intake, said distributor being provided with a push button comprising a spraying member, characterized by the fact that a distribution valve with additional gas intake is used such that the gas / liquid ratio of the mixture distributed is between 95/5 and 99/1 (vol / vol), and that said dispenser is provided with a push button and a nozzle, said nozzle comprising a housing defining an accumulation chamber in which the spraying member sprays the product to be dispensed through a spray nozzle opening into said chamber accumulation, said nozzle having a diameter of between 0.7 and 2 mm, said chamber being closed by a porous sinter constituting at least partially a wall of said chamber re accumulation opposite to that in which is formed the spray nozzle and located at a distance therefrom between 0.5 and 5 mm.
  • the sinter has a thickness of between 0.5 and 4 mm, preferably 0.75 mm; the size of the sintered pores is between 10 and 50 microns, preferably between 15 and 25 microns and more particularly of the order of 20 microns.
  • the non-liquefiable compressed gas is in particular air or nitrogen.
  • a dispenser consists of a container 18 having a bottom 28, and closed at its upper part by a metal cup 3, a seal 2 ensuring the tightness of the closure.
  • the container 18 is filled with a liquid to be sprayed, and with a gas under pressure, for example compressed air.
  • a dispensing valve 7 comprises a valve body 6 and an operating rod 1; the valve body 6, of generally cylindrical shape, has at its upper part a bead 6 has a larger diameter than the rest of the body and allowing the body 6 to be held in place by crimping by the metal cup 3.
  • the transverse upper wall of the cup 3 is pierced with a circular orifice 3 has an annular seal 4, placed inside the bead 6 a , is compressed, during crimping, between the upper wall of the cup 3 and an annular bearing 6 b , concentric with the bead 6 a and carried by the valve body 6, extending to the joint 4 the cylindrical inner wall 25 of the body 6;
  • the operating rod 1 comprises two coaxial cylindrical portions 23 and 24, defining a transverse annular surface 17; the portion 23 of the rod 1 has a diameter slightly less than that of the orifice 3 a of the cup 3, while the portion 24 of the rod 1 has a diameter greater than that of the orifice 3 a , while being slightly smaller than the diameter of the inner wall 25 of the body 6.
  • the portion 23 passes through the seal 4 and the orifice 3 a of the upper wall of the cup 3, the portion 24 is in the chamber 10 defined inside the body 6;
  • the body 6 has, at its lower part, an extension 16, of smaller diameter than that of the rest of the body, along the axis of the body 6, and shaped as a nozzle to which a plunger tube 22, made of plastic, is connected, allowing communication between the chamber 10 and the product to be sprayed contained in the container 18, the dip tube 22 plunging to the vicinity of the bottom 28 of said container.
  • the second cylindrical portion 24 of the rod 1 has an axial blind passage 14 followed by a radial passage 5 passing through the wall of said second portion 24, said axial 14 and radial 5 passages opening respectively into the chamber 10.
  • a blind axial channel 13 is also provided in the first portion 23 of the rod 1; the channel 13 is, moreover, in communication with the outside of the rod 1 by a radial channel 12 passing through the wall of the first portion 23 of the rod 1; the section of said channel 12 through which it opens to the outside is less than the thickness of the joint 4; in the rest position, as shown in the drawing, the channel 12 opens to the right of the thickness of the seal 4.
  • the dispenser comprises a push button 30; the push button 30 comprises a cylindrical body 31 of circular section having at its lower part a housing 32 allowing the fitting of the portion 23 of the rod 1 to place the push button 30 on the container 18.
  • the body 31 carries a col 33; according to an exemplary embodiment, the neck 33 is inclined relative to the axis longitudinal of the body 31.
  • the body 31 and the neck 33 are crossed by channels 37 and 38, in the extension of one another, the channel 37 opening into the housing 32, and the channel 38 ending in a nozzle 39 spray.
  • the dispenser according to the invention operates as follows. From the rest position, as shown in the figure, a downward action on the push button 30, therefore on the operating rod 1, lowers the latter in the body 6; the radial channel 12 is no longer obstructed by the seal 4. Thus, the liquid to be sprayed is pushed by the gas under pressure from the dip tube 22 towards the chamber 10 and the channels 14, 5, 12, 13, and towards the spray nozzle 39; in parallel, the small orifice 8 communicating the upper part of the container containing the pressurized gas with the chamber 10, pressurized gas is also brought to join the nozzle via the upper part of the chamber 10 and the channels 12 and 13; in fact, it is a mixture of propellant gas and liquid product which is sprayed through the spray nozzle 39; the pressure drop through the additional gas intake constituted by the small orifice 8 results in a pressure in the chamber 10 lower than the pressure in the container 18, which allows the distribution of the product, from the container, as described below -above.
  • the neck 33 supports a housing 34 defining a chamber 40 for accumulation; according to the example shown, the housing 34 is cylindrical, of circular section, along an axis perpendicular to the longitudinal axis of the container 18.
  • the nozzle 39 opens into the chamber 40 of the housing 34 which, on the side opposite to the nozzle 39, is closed by a pellet 36 of sintered material held by a support cover 35 clipped onto the housing 34.
  • the nozzle having a diameter between 0.7 and 2 mm, and the pellet 36 being at a distance from the nozzle 39 between 0.5 and 5 mm, the spray produced by the valve 7 is distributed in the form of foam at the outlet of the housing 34.
  • Excellent results have been obtained with a sinter having a thickness of between 0.5 and 4 mm, preferably 0.75 mm , the size of the sintered pores being of the order of 20 microns.
  • the dispenser is advantageously pressurized with compressed air, at a pressure of 1.5 to 6 bars, preferably 3.5 to 6 bars; the section of the orifice 8 is such that the spray produced in the housing 34 contains by volume 95 to 99% of air.
  • the air is replaced by another non-liquefiable compressed gas such as nitrogen.
  • the housing 34 and the push button 30 are in one piece; alternatively, the housing 34 is attached to the conventional button 30 provided.
  • the bottom 28 of the container 18 has a connector 26 provided with a valve 27, for example of the ball valve type, allowing the entry of pressurized gas into the container 18, but opposing its exit.
  • This connector 26 allows connection to a source of pressurized gas, in particular the outlet of a compressor (not shown), which allows the container 18 to be recharged with pressurized gas.
