- This orifice (52) is extended by a tube (53) plunger fixed to the magazine (5), for example, by tight fitting to be easily removable and changeable.
- the plunger tube (53) descends to the bottom of the container (1), under the level of liquid substance (9) in the container (1), and the device remains functional as long as the pipe (53) is immersed in the liquid substance (9).

- the passage (6) being narrower than the width of the magazine (5), the propagation of the mixture accelerates at this passage (6), which has the advantageous effect of stirring the liquid substance and air.
- the passage (6) being divergent with respect to the direction of propagation of the mixture creates a swirling phenomenon at the outlet of the passage (6) which advantageously increases the stirring of the liquid substance and the air.
- a partially emulsified premix of the liquid substance (9) is obtained at the outlet of the variable flow passage (6).
- the premix passes through the foam forming element (7a), rises in level in the perforated cylinder (13) through the succession of rigid wires forming a brush, then passes through the element (7b) of forming foam to finally leave the tank (1 + 2) through the dispensing orifice (11).
- the latter is connected to the chamber (12) of the foam duct, itself connected to the outlet (18) of the foam production device, this outlet (18) guiding the flow of foam for easy reception by the foam. 'user.
- the needle (14) and the non-return valve (54) fall by gravity, the first on its seat (19), thus closing the passage (6) variable flow, and the second at the bottom of the magazine (5), thus closing the orifice (52) of the magazine (5) and retaining the liquid substance (9) contained in the magazine (5).
- the overflow of liquid substance (9) in the magazine (5) spreads in the container (1) through the orifice (51) and the liquid substance (9) in the tube ( 53) plunger is held in the tube (53) by a suction phenomenon related to the closed position of the non-return valve (54).
- the device according to the invention therefore relaxes to its initial configuration. A new device manipulation cycle can begin.
- the container (1) deformable device is provided to be removed from the nozzle (2).
- the container (1) deformable comprises for example a rigid ring at its circular opening so that the tip (2) can snap on.
- the user can fill it with liquid substance (9).
- the device is thus rechargeable by the user.
- a non-limiting embodiment comprising a horizontal mark of maximum filling on the container showing the level of the product by transparency.
- a utensil is added at the foam spraying head.
- the utensil is for example a plastic grid which filters the foam produced to change the consistency of the foam.
- Another example of a device is a cross which separates the jet of foam for example into four smaller jets. The invention thus allows adjustments to produce quantities but also different foam consistencies according to the accessories used or added.
- the foam producing device operates while being held in place by the user.
- the amount of foam produced is not unlimited but a tank (1 + 2) large capacity expels a large amount of air and liquid substance (9) to produce a large amount of foam.
- the tip (2) fits on a container (1) deformable by sealingly attaching a sealing device (21) at the circular opening (20) of the container (1) deformable.
- a user can therefore adapt containers (1) deformable having a different volume, but with an opening of the same size, on the same nozzle (2) container.
- the size of the deformable containers varies for example according to whether the container is more or less bulging or higher or lower.
- the different tank sizes adapt to particular uses. To produce an abundant foam, a large capacity tank will be used and produce only a small amount of foam, for example to save money. an expensive product, a small tank will be used. The more or less flexible nature of the tank also changes the flow rate and type of foam produced.
- the device according to the invention has several advantages. First, the emulsion of the liquid substance with the air starting in the magazine (5) and the variable flow passage (6), that is, before the first foam forming member (7a), increases the quality. finally obtained foam. As a result, also, the quality of the foam obtained depends little on the strength and duration of the pressure exerted by the user. Then, the device does not require any priming phase and has a high reactivity, because of the proximity between the foam-forming device and the reserve of liquid substance that constitutes the magazine (5), and because of the constant maintenance of the liquid substance in the plunger pipe (53). As a result, small jerks make it possible to obtain a quantity of well controlled foam. Finally, since the magazine (5) is larger than the plunger tube (53), the relaxation of the device after releasing the pressure exerted on the container is facilitated, and the breathing of the reservoir is greatly improved, compared with to a foam production device without a magazine (5).

Le magasin (5) a approximativement, mais de façon non limitative, la forme d'un tube à essai, ouvert sur sa partie supérieure cylindrique et fermé par une base arrondie en U. Le magasin est fixé au passage (6) à débit variable, par exemple, par collage de sa partie supérieure ouverte sur le pourtour extérieur cylindrique du passage (6). Le magasin (5) comporte deux orifices qui permettent des échanges de substance liquide (9) et d'air entre le magasin (5) et le réservoir (1+2). Un premier orifice (51) est pratiqué, par exemple, approximativement à mi-hauteur du magasin (5). Cet orifice (51) permet, d'une part, d'évacuer le trop-plein de substance liquide (9) dans le magasin (5), la quantité de substance liquide dans le magasin étant ainsi contrôlée par la position de l'orifice (51), d'autre part, de permettre des échanges d'air entre le réservoir (1+2) et le magasin (5), le magasin se trouvant à l'intérieur du réservoir. Pour le bon fonctionnement du dispositif, il est bien entendu que le niveau de la substance liquide (9) dans le réservoir (1+2) ne doit pas dépasser le niveau de l'orifice (51) du magasin (5). Un deuxième orifice (52) est pratiqué au fond du magasin (5), par exemple, dans sa base arrondie. Cet orifice (52) est prolongé par un tube (53) plongeur fixé au magasin (5), par exemple, par emboîtement serré pour être facilement démontable et changeable. Notamment, des tuyaux plus ou moins longs seront adaptés à des récipients (1) déformables plus ou moins profonds. De préférence, afin d'utiliser toute la substance liquide (9) contenue dans le réservoir (1 +2), le tube (53) plongeur descend jusqu'au fond du récipient (1), sous le niveau de substance liquide (9) dans le récipient (1), et le dispositif reste fonctionnel tant que le tuyau (53) est plongé dans la substance liquide (9). L'orifice (52) est en outre équipé d'un clapet anti-retour (54) empêchant la substance liquide (9) contenue dans le magasin (5) de s'écouler dans le récipient par le tube (53) plongeur. Le clapet anti-retour (54) est par exemple à bille.The magazine (5) has approximately, but not limited to, the shape of a test tube, open on its cylindrical upper part and closed by a rounded U-shaped base. The magazine is fixed to the variable flow passage (6) for example, by bonding its open upper part to the cylindrical outer periphery of the passage (6). The magazine (5) has two orifices that allow exchanges of liquid substance (9) and air between the magazine (5) and the tank (1 + 2). A first port (51) is made, for example, approximately halfway up the magazine (5). This orifice (51) makes it possible, on the one hand, to evacuate the overflow of liquid substance (9) in the magazine (5), the quantity of liquid substance in the magazine thus being controlled by the position of the orifice (51), on the other hand, to allow air exchange between the tank (1 + 2) and the magazine (5), the magazine being inside the tank. For the proper functioning of the device, it is understood that the level of the liquid substance (9) in the reservoir (1 + 2) must not exceed the level of the hole (51) of the magazine (5). A second orifice (52) is formed at the bottom of the magazine (5), for example, in its rounded base. This orifice (52) is extended by a tube (53) plunger fixed to the magazine (5), for example, by tight fitting to be easily removable and changeable. In particular, longer or shorter pipes will be adapted to containers (1) deformable more or less deep. Preferably, in order to use all the liquid substance (9) contained in the reservoir (1 + 2), the plunger tube (53) descends to the bottom of the container (1), under the level of liquid substance (9) in the container (1), and the device remains functional as long as the pipe (53) is immersed in the liquid substance (9). The orifice (52) is further equipped with a non-return valve (54) preventing the liquid substance (9) contained in the magazine (5) from flowing into the container via the plunger tube (53). The non-return valve (54) is for example ball.
La force motrice du dispositif de production de mousse est la pression exercée par l'utilisateur sur le récipient (1) déformable et la propriété d'élasticité du matériau constituant le récipient (1) conférant à ce dernier la capacité de reprendre sa forme initiale après relâchement de la pression exercée par l'utilisateur. La manipulation du dispositif de production de mousse s'effectue par cycle de respiration, chaque cycle comprenant une phase de compression du récipient (1) déformable et une phase de relâchement de la pression exercée sur le récipient (1) élastique pour permettre à celui-ci de reprendre sa forme initiale.The driving force of the foam producing device is the pressure exerted by the user on the deformable container (1) and the property of elasticity of the material constituting the container (1) conferring on the latter the capacity to resume its initial shape after release of the pressure exerted by the user. The foam production device is operated by a breathing cycle, each cycle comprising a compression phase of the deformable container (1) and a release phase of the pressure exerted on the elastic container (1) to allow it to this to resume its original form.
Dans la suite de cette description, nous expliquons le fonctionnement du dispositif de production de mousse selon l'invention en traitant successivement l'une puis l'autre des deux phases d'un cycle de manipulation du dispositif selon l'invention.In the rest of this description, we explain the operation of the foam production device according to the invention by successively treating one then the other of the two phases of a handling cycle of the device according to the invention.
Nous considérons le dispositif dans la configuration initiale suivante : le récipient (1) non déformé et le magasin (5) sont à moitié remplis de substance liquide (9), le pointeau (14) repose sur son siège (19), les clapets obturateurs (4) des orifices (10) d'arrivée d'air reposent sur leur dispositif de maintien (22) et le clapet anti-retour (54) ferme l'orifice (52) retenant ainsi la substance liquide (9) contenue dans le magasin (5).We consider the device in the following initial configuration: the undeformed container (1) and the magazine (5) are half filled with liquid substance (9), the needle (14) rests on its seat (19), the valves shutters (4) of the air intake orifices (10) rest on their holding device (22) and the non-return valve (54) closes the orifice (52) thus retaining the liquid substance (9) contained in the store (5).
Lorsque l'utilisateur exerce une pression sur le récipient (1) qui se déforme, un courant d'air sortant par les orifices (10) débute. Selon le phénomène physique d'aspiration, le clapet obturateur (4) se plaque alors contre les orifices (10) d'arrivée d'air. La pression dans le réservoir maintient alors la membrane contre l'ouverture et une propriété élastique du matériau constituant le clapet permet à celui-ci de réaliser l'étanchéité et d'empêcher la circulation de l'air vers l'extérieur du réservoir (1+2).
Dans le même temps, le magasin (5) est alimenté en substance liquide (9) et en air depuis le réservoir (1+2). D'une part, la substance liquide (9) remonte dans le tuyau (53) plongeur. La substance liquide (9) exerce une poussée, proportionnelle à la pression exercée par l'utilisateur, cette poussée soulevant le clapet anti-retour (54) permettant l'alimentation en substance liquide (9) du magasin (5). D'autre part, une partie de l'air compressé circule du réservoir (1+2) jusque dans le magasin (5) par l'orifice (51) pratiqué dans le magasin (5) approximativement à mi-hauteur.
Ensuite, un premier mélange de substance liquide (9) et d'air se forme et monte en niveau dans le magasin (5) jusqu'à soulever par poussée le pointeau de son siège (19). Le pointeau ainsi soulevé bute contre les éléments (16) de butée et s'agite au passage du mélange. Le passage (6) étant plus étroit que la largeur du magasin (5), la propagation du mélange s'accélère au niveau de ce passage (6), ce qui a l'effet avantageux de brasser la substance liquide et l'air. De plus, le passage (6) étant divergent par rapport au sens de propagation du mélange crée un phénomène de remous en sortie du passage (6) qui augmente avantageusement le brassage de la substance liquide et de l'air. Ainsi, un pré-mélange partiellement émulsifié de la substance liquide (9) est obtenu en sortie du passage (6) à débit variable.When the user exerts pressure on the container (1) which deforms, a stream of air exiting through the orifices (10) begins. According to the physical phenomenon of suction, the shutter valve (4) is then plate against the orifices (10) of air supply. The pressure in the reservoir then holds the membrane against the opening and an elastic property of the material constituting the valve allows it to seal and to prevent the flow of air to the outside of the reservoir (1 2).
At the same time, the magazine (5) is supplied with liquid substance (9) and with air from the reservoir (1 + 2). On the one hand, the liquid substance (9) rises in the pipe (53) plunger. The liquid substance (9) exerts a thrust, proportional to the pressure exerted by the user, this thrust lifting the non-return valve (54) for the supply of liquid substance (9) of the magazine (5). On the other hand, a part of the compressed air flows from the tank (1 + 2) into the magazine (5) through the orifice (51) made in the magazine (5) approximately halfway up.
Then, a first mixture of liquid substance (9) and air is formed and leveled in the magazine (5) until pushing up the needle of its seat (19). The needle thus raised abuts against the abutment elements (16) and agitates as the mixture passes. The passage (6) being narrower than the width of the magazine (5), the propagation of the mixture accelerates at this passage (6), which has the advantageous effect of stirring the liquid substance and air. In addition, the passage (6) being divergent with respect to the direction of propagation of the mixture creates a swirling phenomenon at the outlet of the passage (6) which advantageously increases the stirring of the liquid substance and the air. Thus, a partially emulsified premix of the liquid substance (9) is obtained at the outlet of the variable flow passage (6).
Ensuite, le pré-mélange passe par l'élément (7a) de formation de mousse, monte en niveau dans le cylindre (13) ajouré à travers la succession de fils rigides formant un goupillon, puis passe par l'élément (7b) de formation de mousse pour enfin quitter le réservoir (1+2) par l'orifice de distribution (11). Ainsi, une mousse bien foisonnante est produite au niveau de l'orifice de distribution (11). Ce dernier est connecté à la chambre (12) de conduit de la mousse, elle-même connectée à la sortie (18) du dispositif de production de mousse, cette sortie (18) guidant le débit de mousse pour en facilité la réception par l'utilisateur.Then, the premix passes through the foam forming element (7a), rises in level in the perforated cylinder (13) through the succession of rigid wires forming a brush, then passes through the element (7b) of forming foam to finally leave the tank (1 + 2) through the dispensing orifice (11). Thus, a very abundant foam is produced at the dispensing orifice (11). The latter is connected to the chamber (12) of the foam duct, itself connected to the outlet (18) of the foam production device, this outlet (18) guiding the flow of foam for easy reception by the foam. 'user.
Lorsque l'utilisateur relâche sa pression sur le récipient (1), celui-ci reprend sa forme initiale, grâce aux propriétés élastiques du matériau déformable du récipient (1). Le retour dans sa forme initiale crée une dépression dans le réservoir (1+2) par rapport à la pression extérieure. Chaque clapet obturateur (4) retombe en position de repos sur son dispositif (22) de maintien ouvrant ainsi l'orifice (10) d'arrivée d'air qui lui correspond. L'air est aspiré dans le réservoir (1+2) par les orifices (10) d'arrivée d'air. L'air ne peut donc circuler entre l'intérieur et l'extérieur du réservoir (1+2) par les orifices (10) que dans le sens rentrant.
Dans le même temps, la substance liquide (9) et l'air n'étant plus propulsés en direction du dispositif de formation de mousse, le dispositif de production selon l'invention relaxe. D'un côté, le pointeau (14) et le clapet de non-retour (54) retombent par pesanteur, le premier sur son siège (19), fermant ainsi le passage (6) à débit variable, et le deuxième au fond du magasin (5), fermant ainsi l'orifice (52) du magasin (5) et retenant la substance liquide (9) contenue dans le magasin (5). D'un autre côté, le trop-plein de substance liquide (9) dans le magasin (5) s'épand dans le récipient (1) par l'orifice (51) et la substance liquide (9) présente dans le tube (53) plongeur est maintenue dans le tube (53) par un phénomène d'aspiration lié à la position de fermeture du clapet anti-retour (54).
Le dispositif selon l'invention relaxe donc vers sa configuration initiale. Un nouveau cycle de manipulation du dispositif peut commencer.When the user releases its pressure on the container (1), it returns to its original shape, thanks to the elastic properties of the deformable material of the container (1). The return to its initial form creates a vacuum in the tank (1 + 2) with respect to the external pressure. Each shutter valve (4) falls into the rest position on its holding device (22) thus opening the corresponding air inlet orifice (10). Air is sucked into the tank (1 + 2) through the air inlets (10). The air can therefore flow between the inside and the outside of the tank (1 + 2) through the orifices (10) only in the re-entrant direction.
At the same time, the liquid substance (9) and the air are no longer propelled towards the foam-forming device, the production device according to the invention relaxes. On one side, the needle (14) and the non-return valve (54) fall by gravity, the first on its seat (19), thus closing the passage (6) variable flow, and the second at the bottom of the magazine (5), thus closing the orifice (52) of the magazine (5) and retaining the liquid substance (9) contained in the magazine (5). On the other hand, the overflow of liquid substance (9) in the magazine (5) spreads in the container (1) through the orifice (51) and the liquid substance (9) in the tube ( 53) plunger is held in the tube (53) by a suction phenomenon related to the closed position of the non-return valve (54).
The device according to the invention therefore relaxes to its initial configuration. A new device manipulation cycle can begin.
Le récipient (1) déformable du dispositif est prévu pour être démonté de l'embout (2). Le récipient (1) déformable comprend par exemple une couronne rigide au niveau de son ouverture circulaire pour que l'embout (2) puisse s'enclencher dessus. Lorsque le réservoir est démonté, l'utilisateur peut donc le remplir avec de la substance liquide (9). Le dispositif est ainsi rechargeable par l'utilisateur. Un mode de réalisation non limitatif comprenant une marque horizontale de remplissage maximum sur le récipient laissant voir le niveau du produit par transparence.The container (1) deformable device is provided to be removed from the nozzle (2). The container (1) deformable comprises for example a rigid ring at its circular opening so that the tip (2) can snap on. When the tank is disassembled, the user can fill it with liquid substance (9). The device is thus rechargeable by the user. A non-limiting embodiment comprising a horizontal mark of maximum filling on the container showing the level of the product by transparency.
Dans un mode de réalisation, un ustensile est ajouté au niveau de la tête de projection de la mousse. L'ustensile est par exemple une grille en plastique qui filtre la mousse produite pour changer la consistance de la mousse. Un autre exemple de dispositif est un croisillon qui sépare le jet de mousse par exemple en quatre jets plus petits. L'invention permet ainsi des réglages pour produire des quantités mais aussi des consistances de mousse différentes selon les accessoires utilisés ou ajoutés.In one embodiment, a utensil is added at the foam spraying head. The utensil is for example a plastic grid which filters the foam produced to change the consistency of the foam. Another example of a device is a cross which separates the jet of foam for example into four smaller jets. The invention thus allows adjustments to produce quantities but also different foam consistencies according to the accessories used or added.
De préférence, le dispositif de production de mousse fonctionne en étant tenue à l'endroit par l'utilisateur.Preferably, the foam producing device operates while being held in place by the user.
La quantité de mousse produite n'est pas illimitée mais un réservoir (1+2) de grande capacité permet d'expulser une grande quantité d'air et de substance liquide (9) pour produire une grande quantité de mousse. L'embout (2) s'adapte sur un récipient (1) déformable en se fixant de manière hermétique par un dispositif d'étanchéité (21) au niveau de l'ouverture circulaire (20) du récipient (1) déformable. Un utilisateur peut donc adapter des récipients (1) déformables ayant un volume différent, mais avec une ouverture de même dimension, sur un même embout (2) de récipient. La dimension des récipients déformables varie par exemple selon que le récipient est plus ou moins bombé ou plus ou moins haut. Les différentes tailles de réservoir s'adaptent à des usages particuliers. Pour produire une mousse en abondance, un réservoir de grande capacité sera utilisé et pour ne produire qu'une petite quantité de mousse, afin par exemple d'économiser un produit cher, un petit réservoir sera utilisé. La nature plus ou moins souple du réservoir change également le débit et le type de mousse produite.The amount of foam produced is not unlimited but a tank (1 + 2) large capacity expels a large amount of air and liquid substance (9) to produce a large amount of foam. The tip (2) fits on a container (1) deformable by sealingly attaching a sealing device (21) at the circular opening (20) of the container (1) deformable. A user can therefore adapt containers (1) deformable having a different volume, but with an opening of the same size, on the same nozzle (2) container. The size of the deformable containers varies for example according to whether the container is more or less bulging or higher or lower. The different tank sizes adapt to particular uses. To produce an abundant foam, a large capacity tank will be used and produce only a small amount of foam, for example to save money. an expensive product, a small tank will be used. The more or less flexible nature of the tank also changes the flow rate and type of foam produced.
Le dispositif selon l'invention présente plusieurs avantages. Tout d'abord, l'émulsion de la substance liquide avec l'air commençant dans le magasin (5) et le passage (6) à débit variable, autrement dit avant le premier élément (7a) de formation de mousse, augmente la qualité de la mousse finalement obtenue. De ce fait, également, la qualité de la mousse obtenue dépend faiblement de la force et de la durée de la pression exercée par l'utilisateur. Ensuite, le dispositif ne nécessite aucune phase d'amorçage et présente une grande réactivité, du fait de la proximité entre le dispositif de formation de mousse et la réserve de substance liquide que constitue le magasin (5), et du fait du maintien en permanence de la substance liquide dans le tuyau (53) plongeur. En conséquence, de petits à-coups permettent l'obtention d'une quantité de mousse bien contrôlée. Enfin, le magasin (5) étant de dimensions plus grandes que le tube (53) plongeur, la relaxation du dispositif après relâchement de la pression exercée sur le récipient s'en trouve facilitée, et la respiration du réservoir est grandement améliorée, par rapport à un dispositif de production de mousse sans magasin (5).The device according to the invention has several advantages. First, the emulsion of the liquid substance with the air starting in the magazine (5) and the variable flow passage (6), that is, before the first foam forming member (7a), increases the quality. finally obtained foam. As a result, also, the quality of the foam obtained depends little on the strength and duration of the pressure exerted by the user. Then, the device does not require any priming phase and has a high reactivity, because of the proximity between the foam-forming device and the reserve of liquid substance that constitutes the magazine (5), and because of the constant maintenance of the liquid substance in the plunger pipe (53). As a result, small jerks make it possible to obtain a quantity of well controlled foam. Finally, since the magazine (5) is larger than the plunger tube (53), the relaxation of the device after releasing the pressure exerted on the container is facilitated, and the breathing of the reservoir is greatly improved, compared with to a foam production device without a magazine (5).
Il doit être évident pour les personnes versées dans l'art que la présente invention permet des modes de réalisation sous de nombreuses autres formes spécifiques sans l'éloigner du domaine d'application de l'invention comme revendiqué. Par conséquent, les présents modes de réalisation doivent être considérés à titre d'illustration mais peuvent être modifiés dans le domaine défini par la portée des revendications jointes.It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed. Therefore, the present embodiments should be considered by way of illustration but may be modified in the field defined by the scope of the appended claims.
