Definitions
- the present invention relates to the field of foam production devices by hand pumps operating with a non-deformable container containing a mixture of foaming liquid.
- the present invention relates more particularly to a device for producing foam cream.
- the problem is that the air inlet of the device is placed away from the tank neck downwards. Indeed, if the liquid tank to be foamed is completely filled, the air inlet may be immersed in the liquid preventing air from entering the device. Therefore, when filling the tank, remember to leave a sufficient volume of air so that the air inlet is not in contact with the foaming liquid and can perform its function. This has the disadvantage of not being able to fill the tank with liquid completely and therefore to be obliged to provide a tank larger than the volume of liquid.
- US Pat. Nos. 4,147,306 and 4,156,505 disclose deformable reservoir foamers in which foam is produced when their reservoir is deformed by compression.
- the mixing chamber is above the opening of the tank and the air inlet is made by means of holes at the end of the tank.
- this solution does not allow to incorporate the device inside the tank. Indeed, when the device is large, the air inlet is immersed in the liquid, preventing air from entering the device. This solution therefore makes it necessary to leave the foam production device outside the tank which leads to a device high enough and therefore not very aesthetic or with a tank of small capacity if we want to keep an acceptable size for the device.
- US patent application US 204/060 945 discloses a foam dispenser comprising a deformable reservoir, a housing, and a movable chamber within the housing.
- a deformable annular member is compressed or released by the movable chamber allowing air to flow from the outside of the reservoir inwardly or to flow from the interior of the reservoir to the inside of the chamber through the free space between the moving chamber and the housing of greater diameter.
- this solution can not be applied to the foam dispenser having a non-deformable reservoir. Indeed, the pressure exerted by the pumping means is much lower than when a user presses a deformable reservoir. The pumping means would not allow to compress the annular piece. The air would not enter the room and only the liquid would be pumped.
- Another solution proposed by the prior art consists of a tank with a neck having the same height as the body of the foam producing device. As a result, the air inlet is not immersed in the liquid to be lathered.
- a disadvantage of this solution is a tank having a neck high enough and therefore not very aesthetic.
- the object of the present invention is to overcome certain disadvantages of the prior art by proposing a device for producing foam cream that does not require leaving a large volume of air in the tank and thus making it possible to fill the tank almost completely.
- a device for producing foam cream that can be mounted on a rigid reservoir of liquid to be foamed, comprising a liquid supply duct, a mixing chamber, at least one anti-return device arranged in the chamber. of mixing, at least one air supply duct opening into the mixing chamber, a volume constituting a reserve of foam in communication with the mixing chamber and with an outlet duct, on the one hand, minus a stirring element arranged between the mixing chamber and the foam reserve, a pumping means.
- the air supply duct is formed by the space between two walls, one comprising at least a part of the wall of the mixing chamber and an air inlet and the second wall being different. from the wall of the foaming liquid tank.
- the air supply duct is formed by a groove formed in a part of the body of the device.
- At least one air supply duct is formed by a channel molded into the body of the device.
- At least one air supply duct is formed by a tube running along at least a portion of the wall of the device, connecting an air inlet to the ambient air in a region close to an opening of the foaming liquid tank.

- FIG. 1a shows an exemplary embodiment in which a reservoir (12) of non-deformable foaming liquid (4) is closed by a device for producing foam cream according to the invention.
- the device comprises a liquid supply pipe (1), one end of which is immersed in the liquid to be foamed and the other end is in communication with a mixing chamber (2).
- This conduit (1) may be formed for example and without limitation, by a dip tube whose one end, forming the inlet of the conduit, is disposed in the bottom of the tank (12) of liquid to be foamed (4).
- the other end forming the outlet of the liquid supply duct (1) is embedded in the mixing chamber (2) of the device.
- the end immersed in the liquid reservoir may, for example, be beveled so as to avoid clogging the inlet when the conduit touches the bottom of the tank.
- the liquid supply duct (1) and the mixing chamber (2) are not formed of two separate parts.
- the mixing chamber (2) comprises an anti-return device (3a, 3b) preventing the fluid contained in this chamber (2) from going into the reservoir (12) while allowing a circulation of the reservoir (12) towards the chamber of mixture (2).
- This anti-return device (3a, 3b) can be placed, for example, between the liquid supply duct (1) and the inlet of the mixing chamber (2).
- the anti-return device (3a, 3b) may, for example, be formed by a movable element (3a) such as for example a ball or a needle resting on a substantially frustoconical seat (3c).
- the seat (3c) of the anti-return device (3a, 3b) may for example be formed by a substantially frustoconical portion of the body of the end of the mixing chamber (2) in communication with the liquid supply duct (1). ) forming the inlet of said chamber (2).
- a retaining device (3b) can also be associated with the movable element (3a) so as to limit the stroke of the latter and serve as a stop for the movable element (3a).
- the retaining device (3b) may for example and without limitation, be achieved by a ring or lugs formed or placed on the inner wall of the mixing chamber (2).
- the mixing chamber (2) also comprises one or more air inlets (5) allowing air to enter the chamber (2) thereby allowing the foaming liquid to be mixed with the air to form a foam.
- This air inlet (5) will have a cross section determined according to the cross section of the liquid supply duct (1) so as to have an air / liquid foaming ratio to produce a quality foam. Indeed, too much foaming product (4) and not enough air produces a flowing foam.
- the air inlet (5) is connected to an air supply duct (50).
- This duct (50) has the function of allowing air to enter the mixing chamber (2) even when the air inlet (5) is below the level of the foaming liquid (4).
- the air supply duct (50) may for example be formed by a channel, connecting the air inlet (5) to the ambient air above the filling level of the reservoir (12) of foaming liquid (4). ) for example, at a portion near the opening of said reservoir (12).
- This channel may, for example, be molded along an outer portion of a wall of the device.
- a groove may for example be hollowed in the outer wall of the device at least on a portion of the path of said channel as shown in Figure 2a or 2b. In this embodiment, a groove has been cut on a portion of the outer wall of the mixing chamber (2) of the air inlet (5) to a region near the tank opening (12).
- the groove may for example be made along a portion of the outer wall of the mixing chamber (2) and a part of the reserve of foam (7).
- at least a part of the body of the foam cream production device, comprising one or more air inlets (5) is formed of two parts embedded in each other as illustrated in FIGS. and 1 b.
- the air supply duct (50) is formed by the space between the two envelopes.
- Figure 1b shows a section of the device shown in Figure 1a, along the plane AA '.
- projecting elements (51) such as, for example and without limitation, nipples or ribs keep the two parts separate.
- the projecting elements (51) can be indifferently made on one of the two walls or on both walls.
- complementary shapes may be formed on the wall facing the projecting elements (51) such as a groove cooperating with a nipple or a rib.
- An advantage of these complementary shapes is that they facilitate the insertion of parts during assembly.
- an L-shaped groove may be made to cooperate with a nipple. Such a groove makes it possible to lock the stud and thus and thus to prevent the parts from being broken after assembly.
- the two walls may be of the same shape, for example two substantially concentric or non-concentric shapes. They may also be of different shapes, for example a cylinder inserted inside a wall of substantially oval section.
- An advantage of the different section walls is that in some cases they can make it possible to dispense with the projecting elements (51).
- the duct (50) may be made by a small tube parallel to the body of the device connecting the air inlet (5) to the ambient air for example at the neck of the tank (12) foaming liquid (4) as shown in Figure 2a or 2b.
- the air supply duct (50) may also for example be pierced in the wall of the device.
- the mixing chamber (2) communicates with a foam tank (7). Between the mixing chamber (2) and the foam tank (7), one or more stirring elements (6) are inserted. These stirring elements (6) may be, for example, sieves, grids or any other porous element.
- the product to be foamed (4) comprises an active agent optionally combined with a foaming agent, diluted in water.
- the passage of the liquid foaming / air mixture through the stirring element (s) (6) makes it possible to stir the liquid in the air and transform the latter into foam.
- An anti-return device (30a, 30b) is inserted between the mixing chamber (2) and the foam reserve (7).
- the anti-return device comprises a movable element (30a), such as for example and without limitation, a ball or a needle, resting on a seat (30c) of substantially frustoconical shape.
- a retainer (30b) may also be associated with the movable member (30a) to limit its stroke.
- the retaining device (30b) may for example and without limitation be made by a ring or lugs formed or placed on the inner wall of the foam reserve (7).
- the foam reserve (7) comprises means for pumping the foam.
- This pumping means can be produced, for example and without limitation, by a piston (8a) sliding inside the volume of the foam reserve (7) and an elastic return means (8b) such as a spring.
- the elastic return means (8b) also participates in the stirring. During its movement, it improves the quality of the foam. It also prevents the drying of the foam.
- One end of the outlet duct (9) is integral with the piston (8a) and the cross member allowing the foam contained in the reserve (7) to be expelled.
- a retaining means (8c) such as for example a disk or a ring makes it possible to limit the stroke of the piston (8a) and to prevent it from coming out of the foam reserve (7).
- the pumping means comprises the outlet duct (9), a part of which penetrates inside the volume of the foam reserve (7) and is integral with a movable part in the foam reserve (7).
- the pumping means may also be formed by at least a portion of the deformable and elastic body of the foam reserve (7) as shown in FIG 2a or 2b.
- the compression of the foam reserve (7) expels the foam from the latter and its decompression to suck it from the mixing chamber (2).

- the foam is extracted from the foam reserve (7) via an outlet duct (9) in communication with this reserve (7), for example through the body of the piston (8a) as illustrated in the example of embodiment of Figure 1a or 2.
- One or more filter elements (10) can be inserted between one end of the outlet duct (9) and the foam reservoir (7).
- at least one filter element (10) is inserted into the outlet duct (9).
- a filter element (10) such as a grid, is placed at one end of the outlet duct (9).
- the filter elements (10) can be in the form of sieves, grids or porous elements. These filtering elements (10) are intended to refine the foam by filtering and turn it into foam cream.
- the presence of filtering elements (10) in the outlet duct (9) makes it possible, in certain cases, to suppress the anti-return device (1 1a, 1 1b) also present in this device. led (9).
- This may be the case, for example, when the filter element or elements (10) have very thin openings.
- the filter elements (10) create a strong resistance inside the outlet duct (9) favoring the passage of the foaming liquid / air mixture through the brewing element (6) rather than air through the outlet pipe (9) during decompression of the pumping means.
- This may also be the case when the filter elements (10) are numerous and / or thick. As in the previous case, they create an important resistance inside the outlet duct (9).
- the classic foam is in the form of rather coarse air bubbles, of different sizes and very airy.
- the foam cream is in the form of a foam more homogeneous than the classic foam with more regular bubbles and much thinner.
- the foam cream forms a product denser and more compact than the classic foam. It is in the form of a fluid much less ventilated than the classic foam.
- the foam cream contains more foaming than air from where its consistency approximates that of a gel.
- the foam cream obtained will be all the more compact and with bubbles even more fine and regular that the size of the openings of the filter elements (10) will be fine.
- the quality of the foam cream can also be improved by increasing the number of filter elements (10). In the case of an arrangement of several filter elements (10) in series, it is possible to vary the pore size progressively. Depending on the product to be foamed used, we will start with a filter element having fairly large pores and then use elements having openings increasingly fine. For other products, it will act in reverse.
- the device for producing foam cream may also comprise a blocking system for the pumping means.
- This system may for example be achieved by a pin preventing movement of the piston (8a).
- the system can, for example, be locked by pivoting the outlet duct (9) in one direction and unlocked by rotating it in the opposite direction.
