L'invention va à présent être décrite en référence aux
Les orifices (10) d'arrivée d'air sont combinés avec un dispositif de blocage, comme par exemple une membrane, pour permettre à l'air de circuler uniquement dans le sens d'une aspiration de l'extérieur vers l'intérieur du réservoir. Dans l'exemple non limitatif de réalisation représenté sur la
Lorsque l'utilisateur relâche sa pression sur le réservoir, celui-ci reprend sa forme initiale, grâce aux propriétés élastiques du matériau déformable du réservoir. Le retour dans sa forme initiale, crée une dépression dans le réservoir par rapport à la pression extérieure. L'air est donc aspiré dans le réservoir (1, 2). L'air pénètre par les ouvertures (10) prévues en repoussant la membrane (4b). La membrane repose alors sur le dispositif (22) de maintien. L'air ne peut donc circuler que dans le sens rentrant.When the user releases its pressure on the tank, it returns to its original shape, thanks to the elastic properties of the deformable material of the tank. The return to its original form, creates a depression in the tank relative to the external pressure. The air is sucked into the tank (1, 2). The air enters through the openings (10) provided by pushing back the membrane (4b). The membrane then rests on the holding device (22). The air can therefore circulate only in the incoming direction.
La force motrice de la pompe est la pression exercée par l'utilisateur sur le flacon (1) souple. Lorsque l'utilisateur presse le flacon (1) déformable, une pression s'exerce à l'intérieur du réservoir et la membrane (4) bouche l'ouverture (10) d'arrivée d'air. Le volume d'air compressé va exercer une pression sur le liquide (9) de base qui va être propulsé dans le mélangeur (6) par le tuyau (5) plongeur. D'autre part, une partie de l'air s'échappe par le mélangeur (6) en passant par les ouvertures (13) d'arrivée d'air du mélangeur (6). De la mousse est produite en sortie (11) du mélangeur (6), la sortie (11) du mélangeur (6) étant connectée au chambre (12) de distribution de la mousse. Lorsque l'utilisateur relâche la pression sur le flacon (1) déformable, grâce aux propriétés élastiques du matériau, le flacon (1) reprend sa forme initiale provoquant une aspiration d'air. La membrane (4) qui contrôle le conduit (10) d'alimentation en air va être repoussée, libérant ainsi l'ouverture (10) d'arrivée en air dans le réservoir (1, 2). Le réservoir (1, 2) se remplit alors avec de l'air ambiant. Une fois sa forme retrouvée, une nouvelle pression de l'utilisateur provoque de nouveau la production de mousse. De préférence, la pompe fonctionne en étant tenue à l'endroit par l'utilisateur.The driving force of the pump is the pressure exerted by the user on the flexible bottle (1). When the user presses the deformable bottle (1), a pressure is exerted inside the tank and the membrane (4) closes the opening (10) of air supply. The volume of compressed air will exert a pressure on the liquid (9) base that will be propelled into the mixer (6) by the pipe (5) plunger. On the other hand, a portion of the air escapes through the mixer (6) through the openings (13) of the air inlet of the mixer (6). Foam is produced at the outlet (11) of the mixer (6), the outlet (11) of the mixer (6) being connected to the chamber (12) for dispensing the foam. When the user releases the pressure on the deformable bottle (1), thanks to the elastic properties of the material, the bottle (1) returns to its initial shape causing an aspiration of air. The membrane (4) which controls the air supply duct (10) will be pushed back, thus releasing the air inlet opening (10) into the tank (1, 2). The tank (1, 2) then fills with ambient air. Once its shape is found again, a new pressure of the user again causes the production of foam. Preferably, the pump operates while being held in place by the user.
L'embout (2) de flacon expulse la mousse par une ouverture (11) de distribution de la mousse. La mousse passe ensuite dans le capot (3), par une chambre (12) de distribution de la mousse qui réalise le guidage, la mousse étant disponible pour l'utilisateur à la sortie du conduit (18). L'ouverture (11) de distribution de la mousse relié au mélangeur (6) et ne communique donc pas directement avec le réservoir (1, 2).The mouthpiece (2) of the bottle expels the foam through an opening (11) for dispensing the foam. The foam then passes into the hood (3), by a chamber (12) for dispensing the foam which provides guidance, the foam being available to the user at the outlet of the duct (18). The dispensing opening (11) of the foam connected to the mixer (6) and therefore does not communicate directly with the reservoir (1, 2).
Le mélangeur (6) permet l'émulsion du produit (9) liquide de base avec de l'air pour fabriquer de la mousse. Le liquide (9) de base est amené vers le mélangeur (6) par un tuyau (5) plongeur. L'air est introduit dans le mélangeur (6) par les arrivées (13) d'air. L'air entre dans la chambre du mélangeur et vient en contact avec les différents éléments du mélangeur qui sont par exemple les grilles et le pointeau. Pour produire de la mousse, de l'air et un liquide (9) contenant un agent moussant sont propulsés simultanément dans le mélangeur (6). De même, le liquide pénètre dans la chambre du mélangeur et vient en contact avec les différents éléments du mélangeur comme la grille (7a) d'entrée du tuyau (5) plongeur, la grille (7b) de sortie et le pointeau. Pour réaliser une émulsion, le flux du liquide (9) de base est d'abord perturbé par un pointeau (14) placé dans un logement. Par définition, le pointeau est un régulateur de débit. Une butée (16) maintient le pointeau (14) en place. Lorsque aucune pression n'est exercée sur le flacon par l'utilisateur, le pointeau (14) bouche le conduit du liquide par une légère pression exercée par son poids.The mixer (6) allows the emulsion of the liquid base product (9) with air to make foam. The liquid (9) base is fed to the mixer (6) by a pipe (5) plunger. The air is introduced into the mixer (6) by the arrivals (13) of air. The air enters the chamber of the mixer and comes into contact with the various elements of the mixer which are for example the grids and the needle. To produce foam, air and a liquid (9) containing a foaming agent are propelled simultaneously into the mixer (6). Similarly, the liquid enters the chamber of the mixer and comes into contact with the various elements of the mixer such as the inlet grille (7a) of the pipe (5) plunger, the gate (7b) output and the needle. To achieve an emulsion, the flow of the liquid (9) base is first disturbed by a needle (14) placed in a housing. By definition, the needle is a flow regulator. A stop (16) holds the needle (14) in place. When no pressure is exerted on the bottle by the user, the needle (14) closes the conduit of the liquid by a slight pressure exerted by its weight.
Lorsque l'utilisateur exerce une pression sur le flacon déformable, le produit (9) de base est refoulé dans le tube, le pointeau est soulevé, laissant passer le produit (9) liquide, et modifie le flux du liquide (9) en créant une perturbation qui débute l'émulsion. Plus le flux de liquide est rapide, plus le pointeau est agité. Le pointeau comprend en effet une partie inférieure plongeant dans le tube de liquide et une partie supérieure plus large pour obturer le conduit de liquide au niveau du siège de pointeau. Lors d'une pression exercée par l'utilisateur, l'air dans le réservoir exerce une pression sur le liquide qui est refoulé dans le tuyau (5) plongeur. Plus la pression de l'utilisateur est importante, plus le flux de liquide moussant est important. Plus le flux de liquide sera important et plus le pointeau sera agité violemment. L'agitation du pointeau perturbe ainsi le flux de liquide. Cette perturbation d'une part réduit le débit de liquide et d'autre part réalise une première émulsion du produit liquide et débute la formation de mousse.When the user exerts pressure on the deformable bottle, the product (9) is pushed back into the tube, the needle is lifted, allowing the liquid product (9) to pass, and modifies the flow of the liquid (9) creating a disturbance that starts the emulsion. The faster the flow of liquid, the more the needle is agitated. The needle indeed comprises a lower portion immersed in the liquid tube and a wider upper part to close the liquid duct at the needle seat. During a pressure exerted by the user, the air in the tank exerts a pressure on the liquid which is discharged into the pipe (5) plunger. The greater the pressure of the user, the greater the flow of foaming liquid is important. The higher the flow of liquid, the more the needle will be shaken violently. The agitation of the needle thus disturbs the flow of liquid. This disturbance on the one hand reduces the flow of liquid and on the other hand performs a first emulsion of the liquid product and begins the formation of foam.
D'autre part, l'air se mélange au liquide (9) en partie émulsifié au niveau de la première grille (7a) du mélangeur (6) et au niveau de la deuxième grille (7b) avant d'arriver à l'ouverture (11) de distribution. Selon la pression exercée par l'utilisateur, le liquide est plus ou moins émulsifié après le pointeau (6) agitateur et après la première ou la deuxième grille de filtrage. Selon la pression exercée, l'utilisateur obtiendra un type de mousse différent, la mousse étant plus ou moins légère. La mousse passe ensuite par la chambre (12) de distribution pour sortir par la sortie (18) de la chambre.On the other hand, the air is mixed with the liquid (9) partially emulsified at the first gate (7a) of the mixer (6) and at the second gate (7b) before reaching the opening (11) distribution. According to the pressure exerted by the user, the liquid is more or less emulsified after the needle (6) agitator and after the first or second filtering grid. Depending on the pressure exerted, the user will obtain a different type of foam, the foam being more or less light. The foam then passes through the distribution chamber (12) to exit through the outlet (18) of the chamber.
Le fait de produire la mousse par une pression manuelle sur le flacon (1) déformable, permet de contrôler la qualité de mousse. En effet la mousse a une consistance différente selon que l'utilisateur appuie fort ou doucement. De plus selon que l'utilisateur appuie longtemps ou pendant un court laps de temps, la quantité de mousse produite est différente. 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 produit moussant pour produire une grande quantité de mousse. L'embout (2) de flacon s'adapte sur un flacon (1) déformable en se fixant de manière hermétique par un dispositif d'étanchéité (21) au niveau de l'ouverture circulaire (20) du flacon (1) déformable. Un utilisateur peut donc adapter des flacons (1) déformables ayant un volume différent, mais avec une ouverture de même dimension, sur un même embout (2) de flacon. La dimension des flacons déformables varie par exemple selon que le flacon 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 fact of producing the foam by manual pressure on the deformable bottle (1) makes it possible to control the quality of foam. Indeed the foam has a different consistency depending on whether the user presses hard or soft. Moreover, depending on whether the user presses for a long time or for a short period of time, the quantity of foam produced is different. The amount of foam produced is not unlimited but a tank (1, 2) of large capacity allows to expel a large amount of air and foaming product to produce a large amount of foam. The bottle mouthpiece (2) fits onto a deformable bottle (1) by hermetically sealingly attaching it to a seal (21) at the circular opening (20) of the deformable bottle (1). A user can therefore adapt the deformable bottles (1) having a different volume, but with an opening of the same size, on the same mouthpiece (2) of the bottle. The size of the deformable bottles varies for example according to whether the bottle is more or less bulging or higher or lower. The different tank sizes adapt to particular uses. To produce a foam in abundance, a large capacity tank will be used and to produce only a small amount of foam, for example to save 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.
Une réalisation particulière du mélangeur est représentée en
Dans un exemple de réalisation, le tuyau (5) plongeant dans le liquide est composé de plusieurs parties de tuyau, de diamètre différent, emboîtées les unes dans les autres permettant de retenir le produit le long du conduit. Le tuyau (5) est par exemple fixé au mélangeur par emboîtement serré, pour être facilement démontable et changeable. Notamment des tuyaux plus ou moins longs seront adaptés à des flacons (1) déformables plus ou moins profonds. De préférence, afin d'utiliser tout le produit (9) liquide de base contenu dans le réservoir (1, 2), l'extrémité inférieure du tuyau débouche au niveau de la base du flacon (1) déformable. La pompe reste fonctionnelle tant que le tuyau (5) est plongé dans le liquide (9).In an exemplary embodiment, the pipe (5) immersed in the liquid is composed of several parts of pipe, of different diameter, nested in each other to retain the product along the conduit. The pipe (5) is for example fixed to the mixer by tight fitting, to be easily removable and changeable. In particular, longer or shorter pipes will be adapted to more or less deep deformable vials (1). Preferably, in order to use all the liquid product (9) base contained in the reservoir (1, 2), the lower end of the pipe opens at the base of the vial (1) deformable. The pump remains functional as long as the pipe (5) is immersed in the liquid (9).
Le flacon (1) déformable de la pompe est prévu pour être démonté de l'embout (2) du flacon. Le flacon (1) déformable comprend par exemple une couronne rigide au niveau de son ouverture circulaire pour que l'embout (2) de flacon puisse s'enclencher dessus. Lorsque le réservoir est démonté, l'utilisateur peut donc le remplir avec du produit (9) liquide de base. La pompe est ainsi rechargeable par l'utilisateur. Un mode de réalisation non limitatif comprenant une marque horizontale de remplissage maximum sur le réservoir laissant voir le niveau du produit par transparence, ou à l'intérieur du réservoir.The deformable bottle (1) of the pump is designed to be removed from the mouthpiece (2) of the bottle. The deformable bottle (1) comprises for example a rigid ring at its circular opening so that the tip (2) bottle can snap on. When the tank is disassembled, the user can fill it with liquid product (9) base. The pump is thus rechargeable by the user. A nonlimiting embodiment comprising a horizontal mark of maximum filling on the tank showing the level of the product by transparency, or inside the tank.
Dans un exemple de réalisation le capot (3) peut se déplacer verticalement par rapport à l'embout (2), par une liaison hélicoïdale (17). Dans une position haute du capot (3), la pompe à mousse s'utilise comme décrit précédemment et dans une position basse du capot (3), celui-ci vient boucher les conduits d'alimentation en air et d'expulsion de la mousse. Les bosses (15) du capot (3) sont chacune à égale distance de l'ouverture en vis-à-vis, de façon que chaque ouverture soit fermée dans la position basse du capot. Dans un autre mode de réalisation, le capot (3) est en liaison pivot glissant avec l'embout (2) de flacon et la position basse du capot (3) par rapport à l'embout (2) de flacon est maintenue par un système d'enclenchement, remplaçant la liaison hélicoïdale.In an exemplary embodiment the cover (3) can move vertically relative to the tip (2), by a helical connection (17). In a high position of the cover (3), the foam pump is used as described above and in a low position of the cover (3), it closes the air supply ducts and expulsion of the foam . The bumps (15) of the cover (3) are each equidistant from the opening vis-à-vis, so that each opening is closed in the low position of the cover. In another embodiment, the cover (3) is in sliding pivot connection with the tip (2) of the bottle and the low position of the cover (3) relative to the mouthpiece (2) of the bottle is maintained by a interlocking system, replacing the helical connection.
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 la 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 that 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.
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.
