Definitions

  • the invention relates to a device for dispensing, in expanded form, liquid foaming products according to the preamble of claim 1.
  • Liquid foaming products are often used, for example for hygiene, hairdressing, treatment of skin conditions, maintenance, beauty treatments, etc., which are lathered during use, in the immediate vicinity of the point. of application.
  • a device which comprises a container with a deformable wall, containing a liquid product phase and a gaseous air phase, and a dispensing head are known from the German patent 2,610,219 and the French patent 2,485,955. tightly attached to the container.
  • the head has an internal chamber which permanently communicates with the outside, through a foam outlet nozzle, and with the inside of the container through a porous element.
  • a central tube starts from this chamber, crosses the porous element and is extended into the container by a dip tube which opens near the bottom of the container.
  • the opening of the tube, on the side of the chamber is provided with a one-way valve which allows the entry of fluid into the tube, but not the exit of fluid from the tube.
  • the wall of the central tube is pierced with holes which ensure communication between the porous element and the interior of the tube.
  • This known device has a drawback, in that the density of the foam obtained depends very much on the degree of filling of the container, variations in pressure drop of the porous element under the effect of the residual foam in particular, and the position of the container. For example, if the pressure drop of the porous element is low, in the position of the head-up container, a lot of air passes through the porous element and little or no liquid through the central tube. If the pressure drop increases, the quantity of expelled air tends to decrease and that of the liquid tends to increase.
  • the present invention avoids these drawbacks. It relates to a foam dispenser, capable of supplying a foam whose characteristics remain substantially constant throughout the period of use of the container.
  • It also relates to a distributor of foam, in which the quantity of liquid distributed at each pressure on the container is correctly dosed, with optimal consumption of product.
  • the invention also relates to a foam dispenser which provides the same advantages as above, in all the positions of the container.
  • the dispenser according to the invention is characterized in that it comprises a plunger connected identically to the plunger of the prior art, except that it opens into the gas phase of the container when this is placed head up, and a second plunger which opens into the liquid phase near the bottom of the container and is connected to its upper part, via a chamber or a flare, at the base of head around the porous element.
  • the device comprises a dispensing head 1, tightly fixed in the neck 2 of a container 3.
  • the dispensing head comprises a body 4, a porous mass 5 and a tubular element 6.
  • the body 4 for example made of rigid plastic, has a cylindrical-frustoconical shape with an inner chamber 13, the base 8 of which fits into the neck 2 of the associated container 3, with limitation of penetration by a shoulder 9, and of which the nozzle 14 can optionally be oriented to the side.
  • the tubular element 6 opens into the inner chamber 13 of the head, above the porous mass, through an orifice 11 provided with a ball valve 12.
  • the container 3 is made of a material, such as polyethylene, and of a thickness allowing it to decrease in volume when it is subjected to manual pressure and to quickly resume its normal volume when this pressure is released.
  • a central dip tube 7 extends the tubular element 6, but it opens into the gas phase inside the container placed in the normal position head up, either through 'a side tap, preferably because it is U-shaped with a 180 ° change of direction.
  • a second tube 15 is preferably substantially concentric with the tube 7, so as to define therewith a reduced annular section A.
  • the tube 15 is open at its lower part, near the bottom of the container, and it is flared at its part upper to form a chamber B and connect to the base of the head, around the porous element 5.
  • the weight of the liquid column no longer applies over the entire free surface of the porous element but only on the holes 10, which limits or eliminates the dripping of liquid and the consequences of the change of position.
  • the invention also includes embodiments where the pressure on the container is exerted mechanically, in particular by means of a pump. This is the case in an installation for the permanent production of foam.
  • the device can be used as a foam fire extinguisher.
  • divers 7 and 15 are not necessarily concentric; in this case, they are offset with respect to each other, the plunger 7 passing through chamber B and stopping just outside of it, as illustrated in FIG. 3.
