Definitions
- the invention relates to a device for the distribution, in expanded form, of liquid foaming products.
- Liquid foaming products are often used, for example for hygiene, hairdressing, treatment of skin ailments, maintenance, beauty treatments, etc., which are lathered during use, in the immediate vicinity from the point of application.
- a device which comprises a container with a removable 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. fixed tightly to the container.
- the head has an interior 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, passes through the porous element and is extended into the container by a dip tube which opens near the bottom of the container.
- the orifice of the tube on the side of the chamber, is provided with a unidirectional 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.
- the air is expelled from the container through the porous element, while, under the effect of the same pressure d air, the liquid rises in the central dip tube, passes into the porous element through the holes in the wall of the tube (the cla ⁇ pet being closed in this direction), and mixes with the air in the porous element to generate foam.
- the pressure drop of the porous element is weak, in the position of the container head up, 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. On the contrary, in the upside down position of the same device, a low pressure drop of the porous element or a large filling have the effect of too high a flow of liquid, and a draining of unexpanded liquid, since in this In this case, the entire weight of the liquid column applies directly to the entire surface of the porous element.
- It relates to a foam dispenser, capable of providing a foam, the characteristics of which 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 in an identical manner to the plunger of the prior art, except that it leads into the phase gaseous container when it 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 flar ent , at the base of the head around the porous element.
- Fig. 1 is a view in elevation and in section of a dispenser according to the invention, in its position of use with the head directed upwards,
- Fig. 2 is a similar view but in the position of use upside down, and
- Fig. 3 is a diagram of another embodiment of the invention.
- the apparatus 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 in rigid plastic material, has a cylindrical-frustoconical shape with internal chamber 13, the base 8 of which is inserted 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 porous mass 5 is for example based on polyolefin and has external dimensions allowing it to be inserted into the base 8 of the body 4 and its mechanical retention therein.
- the porous mass is crossed by the tubular element 6 which comprises, in its part corresponding to the porous mass, one and preferably several holes 10.
- the tubular element 6 opens into the interior 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 by through a side connection, 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 upper part to form a chamber B and connect to the base of the head, around the porous element 5.
- the operation of the device according to the invention is as follows; a) The container 3 is filled with liquid to be dispensed, keeping a certain volume of air, for example 20% of the total volume. b) The dispensing head is fixed, for example by screwing with a gasket. c) manual pressure is exerted on the deformable wall of the container 3, placed in a vertical position or inclined head up, which decreases the volume of the gas phase and therefore increases its pressure. This results in a closure of the valve 12, an air passage in the tube 7 and the holes 10, as well as a rise of the liquid in the annular space A between the tubes 7 and 15 and through the porous element 5 as illustrated in FIG. 1.
- the body 2 of the dispensing head 1 is made of rigid plastic, such as rigid polystyrene, polyvinyl chloride, etc.
- the porous plastic mass 5 is made of a plastic material based on POLYOLEFIN. Preferably, its density is close to 0.5 kg / dm 3 and its porosity on the order of 40 to 200 microns,
- the total section of all "orifices. 10 of the tubular element 5 is of the order of 2 to 10 mm 2 , the annular section A then being of the order of 10 to 50 mm 2 , for a annular passage length of about 100 mm.
- the invention also includes embodiments where the pressure on the container is exer ⁇ cated 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. It is understood that modifications of detail can be made in the form and construction of the device according to the invention, without departing from the scope thereof.
- divers 7 and 15 are not necessarily concentric; in this case, they are offset relative to each other, the plunger 7 passing through the chamber B and stopping just outside of it, as illustrated in FIG. 3.
