Abstract

A rotary collar (12) has a base (13) fixed in translation relative to a container (1) and a support (14) formed with a stud (14b). Helical bearing ramps (71,72), parallel to a valve axis, are formed about a dispensing stack (7) and on the location away from the valve side. The stud engages the ramps, facilitating translation of the stack as the collar is rotated.

Description

La présente invention concerne un récipient pressurisé pour la distribution de produits visqueux, ce récipient comportant une valve de distribution qui ménage pour la sortie du produit une section importante du flux sortant.The present invention relates to a pressurized container for the dispensing of viscous products, this container having a dispensing valve that provides for the output of the product a large section of the outflow.

Le problème spécifique de la distribution d'un produit à haute viscosité, tel qu'une crème glacée par exemple, provient du fait qu'il est impératif que la valve de distribution du récipient assure, à l'ouverture, une section de passage suffisante pour réduire au minimum les pertes de charge à l'écoulement du produit. En effet, si la perte de charge sur le flux sortant du produit est trop importante, le débit de produit est insuffisant, sauf à augmenter la pression qui règne à l'intérieur du récipient contenant le produit. Or, une telle augmentation de pression est incompatible avec les règles de sécurité qui doivent être respectées, notamment pour le conditionnement des produits alimentaires. Le problème relatif à ce type de distribution est parfaitement exposé dans la demande de brevet PCT publiée sous le n° WO 03/068632 .The specific problem of dispensing a high-viscosity product, such as an ice cream for example, comes from the fact that it is imperative that the dispensing valve of the container ensures, at the opening, a sufficient passage section to minimize the pressure drops in the flow of the product. Indeed, if the pressure drop on the outflow of the product is too large, the product flow is insufficient, except to increase the pressure inside the container containing the product. However, such an increase in pressure is incompatible with the safety rules that must be respected, especially for the packaging of food products. The problem relating to this type of distribution is perfectly set out in the PCT patent application published under No. WO 03/068632 .

Dans la demande de brevet WO 03/068632 précitée, on décrit un récipient pressurisé pour la distribution d'un produit visqueux, ledit récipient comprenant un conteneur équipé d'une valve de distribution, ladite valve comportant un pot de valve fixé sur le conteneur par sertissage et un clapet qui est solidaire d'une cheminée de distribution déplaçable en translation de façon étanche par rapport au pot de valve ; le clapet est soumis à l'action d'un ressort et coopère avec un siège porté par le pot de valve pour assurer la fermeture de la valve sous l'action du ressort ; pour l'ouverture de la valve, la compression du ressort peut être obtenue par un levier dont le point d'articulation est solidaire du pot de valve et dont le point d'action est solidaire de la cheminée de distribution. Dans une telle valve, à l'ouverture de la valve, le produit à distribuer est éjecté hors du récipient en passant entre le clapet et son siège puis à travers la cheminée de distribution. On peut, sans difficulté, augmenter le diamètre de la cheminée de distribution, d'une part, pour réduire les pertes de charge au passage du produit et, d'autre part, pour augmenter le débit de la distribution. Il en résulte que le seul endroit où se produit une perte de charge significative est le passage entre le clapet et son siège ; le clapet peut être suffisamment éloigné de son siège, à l'ouverture par compression du ressort, et, en conséquence, la perte de charge à cet endroit n'est fonction que du diamètre du siège de clapet, lequel n'est limité que par la dimension du bourrelet de sertissage, qui assure la fixation de la valve.In the patent application WO 03/068632 described above, a pressurized container for dispensing a viscous product, said container comprising a container equipped with a dispensing valve, said valve comprising a valve pot fixed to the container by crimping and a valve which is secured to a distribution duct movable in translation sealingly relative to the valve pot; the valve is subjected to the action of a spring and cooperates with a seat carried by the valve pot to ensure the closure of the valve under the action of the spring; for the opening of the valve, the compression of the spring can be obtained by a lever whose hinge point is integral with the valve pot and whose point of action is integral with the distribution stack. In such a valve, at the opening of the valve, the product to be dispensed is ejected out of the container passing between the valve and its seat and through the distribution shaft. It is possible, without difficulty, to increase the diameter of the distribution stack, on the one hand, to reduce the pressure drop at the passage of the product and, on the other hand, to increase the flow rate of the distribution. As a result, the only place where a significant loss of pressure occurs is the passage between the valve and its seat; the valve can be sufficiently far from its seat, at the opening by compression of the spring, and, as a result, the head loss at this location is a function of the diameter of the valve seat, which is limited only by the size of the crimping bead, which ensures the fixing of the valve.

Ce type de valve donne satisfaction au point de vue de l'écoulement du produit mais présente un inconvénient majeur en ce qui concerne la manoeuvre de la valve par l'utilisateur. En effet, l'utilisateur, pour l'ouverture, doit déplacer avec une main le levier en appliquant une force parallèlement à l'axe du récipient et en maintenant le récipient avec son autre main, ce qui n'est pas un gestuel apprécié par les utilisateurs. D'autre part, pour que la manoeuvre du levier puisse être effectuée même par des enfants, il est nécessaire de donner au levier une longueur minimum, ce qui présente un inconvénient car le levier fait alors saillie sur le côté du récipient, cette saillie étant gênante pour le rangement du récipient et étant, par ailleurs, inesthétique. Cette observation est d'autant plus pertinente que la force exercée par le ressort pour la fermeture de la valve est nécessairement importante afin que la fermeture s'effectue très vite si l'utilisateur relâche son action sur le levier, cette mesure étant requise pour la sécurité de la distribution.This type of valve is satisfactory from the point of view of the flow of the product but has a major drawback with regard to the operation of the valve by the user. Indeed, the user, for opening, must move with one hand the lever by applying a force parallel to the axis of the container and holding the container with his other hand, which is not a gesture appreciated by the users. On the other hand, for the operation of the lever can be performed even by children, it is necessary to give the lever a minimum length, which has a disadvantage because the lever then projects on the side of the container, this projection being annoying for the storage of the container and being, moreover, unsightly. This observation is all the more relevant as the force exerted by the spring for the closing of the valve is necessarily important so that the closing is carried out very quickly if the user releases its action on the lever, this measurement being required for the security of distribution.

La présente invention a pour but de proposer, pour résoudre le problème ci-dessus exposé, un récipient comportant une valve de distribution du même type que ci-dessus décrit ; la solution du problème posé provient du fait que la manoeuvre de ladite valve est réalisée au moyen d'un actuateur rotatif, ce qui supprime l'inconvénient du levier en saillie du système antérieurement connu ci-dessus rappelé, tout en conservant les avantages relatifs à la faiblesse des pertes de charge de distribution. En outre, la manoeuvre de l'actuateur du récipient selon l'invention est appréciée par les utilisateurs sur le plan du gestuel et ne requiert qu'un faible effort pour la commande d'ouverture en raison de la démultiplication que procure l'utilisation d'un système de rampes hélicoïdales. Enfin le récipient proposé par l'invention permet une sécurité de la distribution, notamment pour le cas où la viscosité du produit serait accidentellement réduite, par exemple dans le cas des crèmes glacées par augmentation de température : en effet, dans un tel cas, selon l'invention, il suffit que l'utilisateur relâche l'action de ses doigts sur l'actuateur rotatif pour que la distribution s'arrête par fermeture de la valve sous l'action d'un ressort dont la force peut être importante vu la démultiplication obtenue par les rampes hélicoïdales comme ci-dessus indiqué.The purpose of the present invention is to propose, to solve the above problem, a container having a dispensing valve of the same type as described above; the solution of the problem arises from the fact that the maneuvering of said valve is carried out by means of a rotary actuator, which eliminates the disadvantage of the protruding lever of the previously known system mentioned above, while retaining the advantages relative to low distribution losses. In addition, the operation of the actuator of the container according to the invention is appreciated by the users in terms of gestures and requires only a small effort for the opening control because of the reduction that provides the use of a system of helical ramps. Finally the container proposed by the invention allows a safety distribution, especially for the case where the viscosity of the product would be accidentally reduced, for example in the case of ice cream by temperature increase: indeed, in such a case, according to the invention, it suffices that the user releases the action of his fingers on the rotary actuator so that the distribution stops by closing the valve under the action of a spring whose strength may be important given the reduction obtained by the helical ramps as above indicated.

La présente invention a donc pour objet un récipient pressurisé pour la distribution d'un produit visqueux, ledit récipient comprenant un conteneur équipé d'une valve de distribution, ladite valve comportant un pot de valve fixé sur le conteneur et un clapet, qui est solidaire d'une cheminée de distribution déplaçable en translation de façon étanche par rapport au pot de valve et qui est soumis à l'action d'un ressort, ledit clapet coopérant avec un siège porté par le pot de valve pour assurer la fermeture de la valve sous l'action du ressort, la compression du ressort pouvant être obtenue pour l'ouverture de la valve par un moyen de manoeuvre actionnable par un utilisateur, ledit moyen de manoeuvre agissant sur la cheminée de distribution en prenant appui sur le conteneur de sorte que le produit à distribuer soit éjecté hors du récipient à travers la valve et la cheminée de distribution, caractérisé par le fait que, d'une part, la cheminée de distribution porte extérieurement, du côté opposé à la valve, au moins une rampe hélicoïdale de même axe que la valve et que, d'autre part, le moyen de manoeuvre est un collier rotatif fixe en translation par rapport au conteneur, ledit collier comportant au moins un téton susceptible de venir coopérer avec la (les) rampe(s) hélicoïdale(s) pour provoquer, lors d'une rotation du collier, une translation de la cheminée de distribution.The present invention therefore relates to a pressurized container for dispensing a viscous product, said container comprising a container equipped with a dispensing valve, said valve comprising a valve pot fixed on the container and a valve, which is secured a distribution duct movable in translation sealingly relative to the valve pot and which is subjected to the action of a spring, said valve cooperating with a seat carried by the valve pot to ensure the closure of the valve under the action of the spring, the compression of the spring being obtainable for the opening of the valve by actuating means operable by a user, said actuating means acting on the distribution duct bearing on the container so that the product to be dispensed is ejected from the container through the valve and the distribution stack, characterized in that, on the one hand, the dispensing chimney in externally, on the side opposite the valve, at least one helical ramp of the same axis as the valve and that, on the other hand, the operating means is a rotary collar fixed in translation relative to the container, said collar comprising at least a pin capable of cooperating with the (the) ramp (s) helical (s) to cause, during a rotation of the collar, a translation of the distribution stack.

Dans un mode préféré de réalisation, le (ou les) téton(s) du collier est (sont) déplaçable(s) sensiblement radialement par rapport à leur(s) rampe(s) hélicoïdale(s) d'appui, entre une première position, dans laquelle il y a coopération du téton avec sa rampe associée sous l'effet d'une action de l'utilisateur, et une deuxième position, dans laquelle il n'y a pas de coopération téton/rampe ; le collier est constitué, de préférence, d'une embase fixée sur un moyen d'accrochage du conteneur et d'un support de téton(s) ; le collier peut porter deux tétons diamétralement opposés et le support de téton(s) peut comporter, pour chaque téton, un bras élastique, futilisateur pouvant agir simultanément sur les deux bras élastiques pour provoquer la coopération téton/rampe.In a preferred embodiment, the collar (s) of the collar is (are) displaceable (s) substantially radially relative to their (s) helical ramp (s) support, between a first position, in which there is cooperation of the nipple with its associated ramp under the effect of a user action, and a second position, in which there is no nipple / ramp cooperation; the collar is preferably constituted by a base fixed on a hooking means of the container and a nipple support (s); the collar can carry two diametrically opposed studs and the nipple support (s) may comprise, for each pin, an elastic arm, futilizer can act simultaneously on the two elastic arms to cause the nipple / ramp cooperation.

Avantageusement, la cheminée de distribution a un axe de révolution et les deux rampes hélicoïdales sont symétriques par rapport audit axe ; chacun des bras élastiques du collier peut être relié, par une de ses extrémités, à l'embase et porter à son autre extrémité un téton.Advantageously, the distribution stack has an axis of revolution and the two helical ramps are symmetrical with respect to said axis; each of the elastic arms of the collar can be connected at one of its ends to the base and carry at its other end a nipple.

On peut prévoir que la zone du conteneur, où est fixée la valve, soit de révolution autour d'un axe et que le moyen d'accrochage du conteneur soit un bourrelet de sertissage de révolution autour dudit axe, ledit bourrelet assurant la liaison entre le conteneur et une collerette de sertissage du pot de valve.It can be provided that the zone of the container, where the valve is fixed, is of revolution about an axis and that the means for fastening the container or a crimping bead of revolution about said axis, said bead ensuring the connection between the container and a crimping flange of the valve pot.

Dans une réalisation avantageuse, la cheminée de distribution est constituée de deux pièces cylindriques coaxiales, l'une étant un porte-clapet, qui est solidaire du clapet et coulisse de façon étanche dans le pot de valve, l'autre constituant un embout de distribution, qui forme un chemisage à l'intérieur du porte-clapet ; le porte-clapet peut comporter une collerette périphérique, le ressort étant un ressort hélicoïdal disposé entre ladite collerette et le fond d'une zone cylindrique en doigt de gant du pot de valve, le coulissement du porte-clapet étant guidé par rapport au pot de valve par la paroi du doigt de gant qui est la plus proche de l'axe de la cheminée, une étanchéité étant ménagée entre le porte-clapet et ladite paroi du doigt de gant.In an advantageous embodiment, the distribution stack consists of two coaxial cylindrical parts, one being a valve holder, which is integral with the valve and slides in a sealed manner in the valve pot, the other constituting a dispensing nozzle which forms a liner inside the valve holder; the valve-holder may comprise a peripheral collar, the spring being a helical spring disposed between said collar and the bottom of a cylindrical zone in the thimble of the valve pot, the sliding of the valve-holder being guided relative to the pot of valve by the wall of the thimble which is closest to the axis of the chimney, a seal being provided between the valve-holder and said wall of the thimble.

On peut prévoir que l'embout de distribution porte extérieurement les deux rampes hélicoïdales de la cheminée de distribution et comporte un logement cylindrique en doigt de gant, qui s'adapte sur la partie du porte-clapet située du côté de sa collerette où ne se trouve pas le clapet ; la collerette du porte-clapet peut comporter au moins une encoche, qui reçoit une languette solidaire de l'embout de distribution, ladite languette assurant une solidarisation amovible par encliquetage entre l'embout de distribution et le porte-clapet, pour permettre la désolidarisation dudit embout.It is possible for the dispensing nozzle to carry the two helical ramps of the distribution stack externally and to have a cylindrical housing in a glove finger, which fits on the portion of the valve holder situated on the side of its collar where not find the flap; the flange of the valve holder may comprise at least one notch, which receives a tab integral with the dispensing nozzle, said tongue ensuring a removable fastening snap between the dispensing nozzle and the valve holder, to allow the separation of said tip.

Etant donné que l'action des tétons sur les rampes hélicoïdales au cours de la rotation du collier risque d'entraîner en rotation la cheminée de distribution malgré la présence de l'étanchéité réalisée entre ladite cheminée et le pot de valve, on a prévu que la cheminée de distribution et le pot de valve peuvent être bloqués en rotation l'un par rapport à l'autre par un dispositif de rainures et nervures parallèles à l'axe de ladite cheminée ; le pot de valve peut comporter intérieurement deux couples de nervures diamétralement opposés et la cheminée de distribution peut comporter, à sa périphérie, deux couples de rainures correspondants ; la languette de l'embout de distribution peut être positionnée entre les deux rainures d'un couple de rainures de la cheminée de distribution.Since the action of the pins on the helical ramps during the rotation of the collar may cause rotation of the distribution duct despite the presence of the seal made between said chimney and the valve pot, it has been provided that the distribution duct and the valve pot can be locked in rotation relative to each other by a device with grooves and ribs parallel to the axis of said chimney; the valve pot may internally comprise two pairs of diametrically opposed ribs and the distribution stack may comprise, at its periphery, two pairs of corresponding grooves; the tongue of the dispensing nozzle can be positioned between the two grooves of a pair of grooves of the distribution chimney.

Avantageusement, le collier porte, sur la face intérieure de son embase, un bossage venant se placer dans une fenêtre pratiquée dans le pot de valve, du côté de la collerette de sertissage où ne se trouve pas le clapet ; quand l'utilisateur imprime une rotation au collier, le bossage sort de sa fenêtre par déformation de l'embase et la position de ladite fenêtre sur le pot de valve correspond, quand le bossage y est logé, à une position du collier, dans laquelle les deux tétons sont au droit des points bas des deux rampes hélicoïdales. De préférence, au moins une rampe hélicoïdale comporte, à sa partie haute, une butée limitant la rotation du collier : lorsque par rotation du collier, les tétons arrivent au contact de ladite butée, on a opéré l'enfoncement maximum de la cheminée de distribution et du clapet, donc l'ouverture maximum de la valve qui correspond au débit maximum du récipient.Advantageously, the collar carries, on the inner face of its base, a boss coming to be placed in a window made in the valve pot, on the side of the crimping flange where the valve is not located; when the user prints a rotation to the collar, the boss comes out of his window by deformation of the base and the position of said window on the valve pot corresponds, when the boss is housed therein, at a position of the collar, wherein the two nipples are at the low points of the two helical ramps. Preferably, at least one helical ramp comprises, at its upper part, an abutment limiting the rotation of the collar: when by rotation of the collar, the studs come into contact with said stop, the maximum depression of the distribution pipe has been made and the valve, so the maximum opening of the valve which corresponds to the maximum flow of the container.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire ci-après, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the invention will be described below, by way of purely illustrative and non-limiting example, an embodiment shown in the accompanying drawing.

En se référant au dessin, on voit que l'on a désigné par 1 le conteneur métallique du récipient pressurisé selon l'invention. Ce conteneur 1 a une forme cylindrique et il s'ouvre vers l'extérieur par le collet d'une ogive 1a, ledit collet étant conformé en un bourrelet de sertissage 1b, qui entoure l'ouverture circulaire par laquelle l'intérieur du conteneur 1 communique avec l'extérieur en l'absence de tout dispositif fixé sur ledit bourrelet de sertissage. Sur le conteneur 1, on a fixé une valve de distribution qui comporte un pot de valve 2 de forme cylindrique, le pot de valve 2 étant équipé d'une collerette de sertissage 2a, qui est destinée à venir en appui sur le bourrelet de sertissage 1b avec interposition d'un joint d'étanchéité 3. La fixation du pot de valve 2 sur le conteneur 1 est réalisée, de façon connue, au moyen d'une rondelle métallique que l'on sertit pour former un anneau 4 ; ledit anneau 4 enserre le bourrelet de sertissage 1b, le joint 3 et la collerette 2a en remontant, en outre, un peu le long de la paroi cylindrique du pot de valve, qui est adjacente à la collerette de sertissage 2a, du côté où ne se trouve pas le bourrelet de sertissage 1b.Referring to the drawing, it is seen that 1 has designated the metal container of the pressurized container according to the invention. This container 1 has a cylindrical shape and opens outwardly by the collar of a warhead 1a, said collar being configured as a crimping bead 1b, which surrounds the circular opening through which the interior of the container 1 communicates with the outside in the absence of any device attached to said crimping bead. On the container 1, there is fixed a dispensing valve which comprises a valve pot 2 of cylindrical shape, the valve pot 2 being equipped with a crimping flange 2 has , which is intended to bear against the bead of crimping 1b with interposition of a seal 3. The fixing of the valve pot 2 on the container 1 is carried out, in known manner, by means of a metal washer which is crimped to form a ring 4; said ring 4 encloses the crimping bead 1b, the seal 3 and the flange 2 has up further slightly along the cylindrical wall of the valve pot, which is adjacent the seaming flange 2a, the side where the crimping bead is not located 1 b .

Le pot de valve 2 comporte dans sa partie basse, c'est-à-dire dans sa partie qui est à l'intérieur du conteneur 1, une zone constituant un doigt de gant cylindrique 2b délimitée entre la paroi cylindrique externe 2c du pot de valve 2, une paroi cylindrique interne 2d coaxiale avec la paroi cylindrique 2c et une paroi 2e constituant le fond du doigt de gant 2b, ladite paroi 2e étant sensiblement perpendiculaire à l'axe commun des parois cylindriques 2c et 2d. La paroi 2e est solidarisée avec un siège de clapet 5 de forme tronconique. Dans le doigt de gant cylindrique 2b, on a mis en place un ressort hélicoïdal 6, dont la partie supérieure a un diamètre légèrement plus petit que celui de la partie inférieure, laquelle se trouve logée dans le doigt de gant cylindrique 2b.The valve pot 2 comprises in its lower part, that is to say in its part which is inside the container 1, a zone forming a cylindrical pocket 2b delimited between the outer cylindrical wall 2 c valve pot 2, an inner cylindrical wall 2 d coaxial with the cylindrical wall 2c and a wall 2 e constituting the bottom of the glove finger 2 b, said wall 2 e being substantially perpendicular to the common axis of the cylindrical walls 2 c and 2 d . The wall 2 e is secured to a valve seat 5 of frustoconical shape. In the cylindrical thimble 2b , a helical spring 6 has been put in place, the upper part of which has a diameter slightly smaller than that of the lower part, which is housed in the cylindrical thimble 2b .

La valve du récipient selon l'invention comporte, en outre, une cheminée de distribution qui est constituée de deux pièces, à savoir un embout de distribution désigné par 7 dans son ensemble et un porte-clapet désigné par 8 dans son ensemble. Le porte-clapet 8 est constitué d'une paroi cylindrique 8c qui porte à sa partie inférieure, c'est-à-dire du côté de l'intérieur du conteneur 1, trois bras en étoile 8a partant de la paroi cylindrique 8c du porte-clapet 8 pour arriver à une douille 8b, dont l'axe est confondu avec l'axe de la paroi cylindrique 8c du porte-clapet 8. La douille 8b reçoit la queue de liaison 9 d'un clapet conique 10, ladite queue de liaison 9 étant maintenue dans la douille 8b par un bourrelet d'encliquetage 9a. La pointe conique du clapet 10 est dirigée vers le bas et la grande base du cône formé par le clapet 10 comporte un logement où est mis en place un joint d'étanchéité 11 en forme de rondelle circulaire, ladite rondelle entourant la queue de liaison 9. La paroi cylindrique 8c coopère, par son extrémité basse, avec la paroi cylindrique 2d avec interposition d'un joint torique d'étanchéité 21 ; la paroi cylindrique 2d constitue un guide de coulissement pour le porte-clapet 8. La partie cylindrique 8c du porte-clapet 8 comporte extérieurement une collerette périphérique 8d, qui se trouve à peu près à mi-distance entre les deux extrémités de ladite paroi cylindrique 8c. Le ressort 6 est mis en place entre la paroi 2e du doigt de gant cylindrique 2b et la collerette périphérique 8d ; l'appui du ressort 6 sur la collerette périphérique 8d s'effectue dans la zone où la collerette 8d se raccorde à la paroi cylindrique 8c du porte-clapet 8.The valve of the container according to the invention further comprises a dispensing chimney which consists of two parts, namely a dispensing nozzle designated by 7 as a whole and a valve holder designated by 8 as a whole. The valve holder 8 consists of a cylindrical wall 8 c which carries at its lower part, that is to say the side of the interior of the container 1, three arm star 8a extending from the cylindrical wall 8 c of the valve holder 8 to arrive at a bushing 8b , whose axis coincides with the axis of the wall cylindrical 8c of the valve holder 8. The sleeve 8 b receives the linking stem 9 of a cone valve 10, said linking stem 9 being held in the sleeve 8 b by a snap bead 9 a. The conical tip of the valve 10 is directed downwards and the large base of the cone formed by the valve 10 comprises a housing where is placed a seal 11 in the form of a circular washer, said washer surrounding the connecting tail 9 . the cylindrical wall 8c cooperates, by its lower end with the cylindrical wall 2d with the interposition of a sealing O-ring 21; the cylindrical wall 2 d constitutes a sliding guide for the valve holder 8. The cylindrical portion 8c of the valve holder 8 externally has a peripheral collar 8 d , which is approximately halfway between the two ends of the said cylindrical wall 8c . The spring 6 is placed between the wall 2 e of the cylindrical thimble 2 b and the peripheral collar 8 d ; the support of the spring 6 of the peripheral flange 8 d is carried out in the area where the flange 8d is connected to the cylindrical wall 8 c of the valve holder 8.

L'embout de distribution 7 est la pièce, qui définit le canal de sortie 7a du produit distribué. Dans la réalisation représentée sur le dessin, ce canal de sortie 7a présente une section de passage en forme d'étoile, mais il est clair que la section du canal 7a peut être quelconque. L'embout de distribution 7 comporte une paroi cylindrique 7b qui constitue un chemisage intérieur pour le porte-clapet 8. La partie de l'embout de distribution 7, qui se trouve entre le canal de sortie 7a, d'une part, et le niveau de la collerette périphérique 8d, d'autre part, forme un doigt de gant cylindrique, où est logée la partie de la paroi cylindrique 8c qui se trouve au-dessus de la collerette périphérique 8d, c'est-à-dire du côté de cette collerette périphérique où ne se trouve pas le ressort 6. L'embout de distribution 7 peut ainsi venir s'assembler sur la partie supérieure du porte-clapet 8 ; on a désigné par 7c la paroi cylindrique externe qui, avec la paroi cylindrique interne 7b, définit le doigt de gant cylindrique où est mise en place la partie supérieure du porte-clapet 8. La base de la paroi cylindrique 7c constitue un anneau 7d, qui vient reposer par sa face inférieure sur la collerette périphérique 8d. La face supérieure de l'anneau 7d forme deux rampes hélicoïdales 71, 72 symétriques l'une de l'autre par rapport à l'axe de l'embout de distribution 7. Chacune de ces rampes hélicoïdales se termine, en son point haut, par une butée 73.The dispensing nozzle 7 is the part which defines the outlet channel 7 has the dispensed product. In the embodiment shown in the drawing, this outlet channel 7 a has a passage section star-shaped, but it is clear that the channel section 7 may be one. The dispensing nozzle 7 has a cylindrical wall 7b which constitutes an inner liner for the valve holder 8. The portion of the dispensing nozzle 7, which is located between the outlet channel 7 has , on the one hand, and the level of the peripheral flange 8 d , on the other hand, forms a cylindrical thimble where the portion of the cylindrical wall 8 c is located above the peripheral flange 8 d , that is, that is to say on the side of this peripheral flange where is not the spring 6. The dispensing nozzle 7 can thus be assembled on the upper part of the valve holder 8; 7 c is the external cylindrical wall which, together with the internal cylindrical wall 7 b , defines the cylindrical thimble where the upper part of the valve holder 8 is placed. The base of the cylindrical wall 7 c constitutes a ring 7 d , which comes to rest by its lower face on the peripheral collar 8 d . The upper face of the ring 7 d forms two helical ramps 71, 72 symmetrical to each other with respect to the axis of the dispensing nozzle 7. Each of these helical ramps ends at its high point. , by a stop 73.

La valve, dont les éléments principaux viennent d'être décrits, est en position de fermeture, lorsque le ressort 6 amène le joint 11 du clapet 10 contre le siège 5 sous l'action du ressort 6, ce qui est représenté sur la figure 1. La valve passe en position d'ouverture (voir figure 2) lorsque l'on comprime le ressort 6 pour faire descendre la cheminée de distribution 7-8 dans le pot de valve 2, ce qui entraîne le clapet 10 : le produit à distribuer passe alors entre le clapet 10 et le siège de clapet 5 ; il traverse la zone où sont disposés les bras 8a, remonte dans le canal défini par la paroi cylindrique 7b et s'échappe vers l'extérieur par le canal de sortie 7a.The valve, whose main elements have just been described, is in the closed position, when the spring 6 brings the seal 11 of the valve 10 against the seat 5 under the action of the spring 6, which is represented on the figure 1 . The valve moves to the open position (see figure 2 ) when the spring 6 is compressed to lower the distribution stack 7-8 in the valve pot 2, which causes the valve 10: the product to be dispensed then passes between the valve 10 and the valve seat 5; it passes through the zone where the arms 8 are arranged has, upwardly through the channel defined by the cylindrical wall 7 b and escapes outwardly through the outlet channel 7 a.

Pour provoquer la compression du ressort 6, on agit sur les rampes hélicoïdales 71, 72 au moyen d'un collier désigné par 12 dans son ensemble. Le collier 12 est constitué de deux sous-ensembles liés l'un à l'autre, à savoir une embase désignée par 13 dans son ensemble et un support de tétons désigné par 14 dans son ensemble. Les deux sous-ensembles 13 et 14 du collier 12 sont moulés d'une seule pièce pour constituer ledit collier 12 et sont reliés entre eux par deux zones de liaison 15, lesdites zones de liaison 15 étant bien visibles sur les figures 2 et 7 ; en dehors des zones 15, les deux sous-unités du collier 12 sont séparées l'une de l'autre.To cause compression of the spring 6, it acts on the helical ramps 71, 72 by means of a collar designated by 12 as a whole. The collar 12 consists of two sub-assemblies connected to each other, namely a base designated by 13 as a whole and a nipple support designated by 14 as a whole. The two subassemblies 13 and 14 of the collar 12 are molded in one piece to form said collar 12 and are interconnected by two connecting zones 15, said connecting zones 15 being clearly visible on the figures 2 and 7 ; outside the zones 15, the two sub-units of the collar 12 are separated from each other.

L'embase 13 vient s'adapter sur la partie supérieure du pot de valve 2 à la périphérie de celle-ci. La partie supérieure de l'embase 13 entoure le pot de valve 2 dans sa partie située au dessus de la collerette de sertissage 2a ; la partie inférieure de l'embase 13 constitue une jupe, qui entoure l'anneau 4 de sertissage et qui vient s'encliqueter par un bossage annulaire 13a au-dessous dudit anneau 4 de sertissage. La mise en place de cet encliquetage de l'embase 13 sur l'anneau 4 de sertissage est rendue possible par la présence de fentes 16 disposées de place en place, régulièrement, à la périphérie de l'embase pour donner à la jupe la souplesse nécessaire à l'encliquetage. L'embase 13 est ainsi maintenue sur le conteneur 1, sans possibilité de translation par rapport à l'axe du conteneur mais elle est libre en rotation autour dudit axe, la rotation s'effectuant autour de l'anneau 4, qui sert de guide.The base 13 fits on the upper part of the valve pot 2 at the periphery thereof. The upper part of the base 13 surrounds the valve pot 2 in its portion located above the crimping flange 2 a ; the lower part of the base 13 constitutes a skirt which surrounds the crimping ring 4 and which snaps by an annular boss 13 has below said four crimping ring. The introduction of this snap of the base 13 on the crimping ring 4 is made possible by the presence of slots 16 arranged in place, regularly, at the periphery of the base to give the skirt the flexibility necessary for snapping. The base 13 is thus maintained on the container 1, without the possibility of translation relative to the axis of the container but is free to rotate about said axis, the rotation being effected around the ring 4, which serves as a guide .

Le support de tétons 14 comporte deux bras élastiques 14a symétriques par rapport à l'axe du collier 12. Chacun de ces bras 14a est relié par une de ses extrémités à une des zones de liaison 15 et porte, à son autre extrémité, un téton 14b qui est disposé radialement au droit d'une platine d'appui 14c destinée à l'action des doigts de l'utilisateur sur les bras 14a ; chaque bras 14a a une forme voisine de celle d'un demi-cercle quand il est vu en plan selon l'axe du collier 12. Lorsque l'utilisateur n'appuie pas sur les platines 14c, l'élasticité des bras 14a fait que les tétons 14b ne peuvent pas venir en contact avec les rampes hélicoïdales 71, 72. Au contraire, lorsque l'utilisateur exerce une pression radiale sur les platines 14c, les tétons 14b peuvent venir en contact avec lesdites rampes hélicoïdales.The support pins 14 has two resilient arms 14a are symmetrical with respect to the axis of the collar 12. Each of these arms 14 a is connected by one of its ends to one of the connecting regions 15 and carries at its other end, a stud 14 b which is arranged radially in a bearing plate 14 c for the action of the fingers of the user on the arms 14 a; each arm 14 has a shape close to that of a semicircle when it is seen in plan along the axis of the collar 12. When the user does not press on the plates 14 c , the elasticity of the arms 14 made the nipples 14b can not contacting the helical ramps 71, 72. On the contrary, when the user exerts a radial pressure on the plates 14 c, the studs 14b are engageable with said helical ramps.

Les zones de liaison 15, se prolongent du côté opposé à chacun des bras élastiques 14a par des doigts rigides 15a (figures 3, 4, 7 et 13) qui, comme montré à la figure 4 viennent au contact des bras 14a en se logeant dans les décochements 14d (figure 13) de forme complémentaire ménagés dans la paroi interne des bras 14a lorsque l'utilisateur exerce une pression radiale sur les platines 14c. Dans cette position des bras les doigts 15a servent de butées pour maintenir les bras élastiques dans un plan horizontal.Link 15 of the zones extend on the side opposite each of the elastic arm 14 has by rigid fingers 15 a ( Figures 3, 4 , 7 and 13 ) which, as shown in figure 4 come into contact with arm 14 has fitting into the décochements 14 d ( figure 13 ) of complementary shape formed in the inner wall of the arms 14 a when the user exerts a radial pressure on the plates 14 c . In this position the arm 15 has the fingers serve as stops for holding the elastic arms in a horizontal plane.

L'embase 13 porte sur sa face interne, au-dessus de la zone où se trouvent les fentes 16, un léger bossage 13b, qui est susceptible de venir se loger dans une encoche 2f ménagée au même niveau dans la paroi cylindrique 2c du pot de valve 2, juste au-dessus de la bordure du feuillet métallique, qui assure extérieurement le sertissage au niveau de l'anneau 4. Si l'on entraîne en rotation l'embase 13 par rapport au conteneur 1, le léger bossage 13b sort de son logement 2f et s'appuie sur la paroi cylindrique 2c du pot de valve 2. Le bossage 13b permet une indexation de la position angulaire de l'embase 13 par rapport au conteneur 1 ; cette indexation correspond à un positionnement des tétons 14b au droit des points bas des rampes hélicoïdales 71, 72.The base 13 bears on its inner face, above the area where the slots 16 are located, a slight boss 13b , which is likely to be housed in a notch 2 f formed at the same level in the cylindrical wall 2 c of the valve pot 2, just above the edge of the metal sheet, which externally ensures crimping at the level of the ring 4. If the base 13 is rotated relative to the container 1, the light weight boss 13 b out of its housing 2 f and is based on the cylindrical wall 2 c of the valve pot 2. The boss 13 b allows indexing of the angular position of the base 13 relative to the container 1; this index corresponds to a positioning of the studs 14 b on the right of the low points of the helical ramps 71, 72.

Pour provoquer la translation de la cheminée de distribution 7-8 par rapport au pot de valve 2 en vue de l'ouverture de la valve, l'utilisateur appuie sur les platines 14c, ce qui amène celles-ci au contact des rampes hélicoïdales 71, 72 et l'utilisateur effectue ensuite un mouvement de rotation dans le sens où les tétons se déplacent sur lesdites rampes en direction des butées 73. Dans ce cas, étant donné que le collier 12 est fixe en translation par rapport au conteneur 1, la cheminée de distribution 7-8 se déplace vers le bas, c'est-à-dire provoque l'ouverture de la valve par descente du clapet 10. Il est essentiel dans ce mouvement de rotation d'éviter que les tétons 14b ne soient soulevés verticalement lorsqu'ils se déplacent par rapport aux rampes 71, 72 sous l'effet de la pression du ressort 6, auquel cas le collier 12 ne serait plus fixe en translation par rapport au conteneur 1 et la cheminée de distribution ne se déplacerait pas vers le bas par rapport au pot de valve. Cette fonction est réalisée par les doigts 15a. Il est également essentiel dans ce mouvement de translation que la cheminée de distribution ne puisse pas tourner par rapport au pot de valve. En conséquence, on a prévu de ménager, dans les collerettes 7d et 8d, deux couples de rainures, respectivement 17 et 17a, parallèles à l'axe de la cheminée de distribution, qui coopèrent avec deux couples de nervures 18 pratiquées sur la face intérieure de la paroi cylindrique 2c du pot de valve 2. L'un des couples rainures/nervures (17, 18) et (17a, 18) se trouve de part et d'autre de l'encoche 2f, qui constitue le logement du léger bossage 13b ; entre les deux rainures (17, 17a) de ce couple, on a ménagé une languette 19 solidaire de l'embout de distribution 7, languette qui pénètre dans une encoche 20 pratiquée dans la collerette 8d ; cette languette comporte à son extrémité libre un bourrelet 19a. La mise en place de la languette 19 dans l'encoche 20 permet, par le bourrelet 19a, le maintien de l'embout de distribution 7 par rapport au porte-clapet 8 ; cependant, les dimensions du bourrelet 19a par rapport à l'encoche 20 et au jeu existant entre la cheminée de distribution et la paroi cylindrique 2c du pot de valve 2 permet, par élasticité de la languette 19, une désolidarisation de l'embout de distribution 7 par rapport au porte-clapet 8 sous l'effet d'une traction effectuée sur l'embout de distribution parallèlement à son axe. De la sorte, l'embout de distribution est amovible, ce qui permet son nettoyage entre deux distributions successives.To cause the translation duct 7-8 to be displaced relative to the valve pot 2 in order to open the valve, the user presses on the plates 14c , which brings them into contact with the helical ramps. 71, 72 and the user then performs a rotational movement in the direction that the pins move on said ramps towards the stops 73. In this case, since the collar 12 is fixed in translation relative to the container 1, the distribution pipe 7-8 moves downwards, that is to say causes the valve to open by lowering the valve 10. It is essential in this rotational movement to prevent the nipples 14 b are lifted vertically when they move relative to the ramps 71, 72 under the effect of the pressure of the spring 6, in which case the collar 12 would no longer be fixed in translation relative to the container 1 and the distribution chimney would not move not down compared to u valve pot. This function is performed by the fingers 15 a . It is also essential in this translational movement that the distribution chimney can not rotate relative to the valve pot. As a result, provision has been made to protect the flanges 7 d and 8 d , two pairs of grooves, respectively 17 and 17 a , parallel to the axis of the distribution stack, which cooperate with two pairs of ribs 18 formed on the inner face of the cylindrical wall 2 c of the valve pot 2 . One of the couples grooves / ribs (17, 18) and (17 a, 18) located on either side of the notch 2 f, which is the accommodation of slight boss 13 b; between the two grooves (17, 17 a ) of this pair, there is formed a tab 19 integral with the dispensing tip 7, tongue which penetrates into a notch 20 formed in the collar 8 d ; the tongue has at its free end a flange 19 a. The introduction of the tongue 19 in the notch 20 allows, by the bead 19 has the maintenance of the dispensing nozzle 7 relative to the valve holder 8; however, the bead 19 has dimensions relative to the slot 20 and the clearance between the dispensing stack and the cylindrical wall 2c of the valve pot 2 allows, by elasticity of the tongue 19, a disconnection of the endpiece 7 distribution relative to the valve holder 8 under the effect of a traction performed on the dispensing nozzle parallel to its axis. In this way, the dispensing nozzle is removable, which allows its cleaning between two successive distributions.

Le montage du récipient selon l'invention s'effectue en fixant d'abord le pot de valve par sertissage sur le conteneur 1. Après quoi, on met en place le ressort 6, puis le porte-clapet 8 et en comprimant le ressort 6, on fixe le clapet 10 dans sa douille de maintien 8b. On relâche l'action sur la compression du ressort 6 et on positionne l'embout de distribution 7 sur le porte-clapet 8, ce qui entraîne l'encliquetage de la languette 19. La mise en place du porte-clapet 8 et de l'embout de distribution 7 s'effectue avec engagement des nervures 18 dans les rainures (17, 17a). On met alors en place le collier 12 en encliquetant l'embase 13 sur l'anneau 4 de sertissage, le bossage 13b venant se mettre en place dans son encoche 2f. A ce moment les tétons 14b se trouvent en vis-à-vis des points bas des rampes hélicoïdales 71, 72.The assembly of the container according to the invention is effected by first fixing the valve pot by crimping on the container 1. After that, it sets up the spring 6, then the valve holder 8 and compressing the spring 6 the valve 10 is fixed in its retaining sleeve 8b . The action is released on the compression of the spring 6 and the dispensing nozzle 7 is positioned on the valve holder 8, which causes the tongue 19 to snap. The positioning of the valve holder 8 and the dispensing nozzle 7 is made with engaging ribs 18 in the grooves (17, 17 a ). The collar 12 is then put in place by snapping the base 13 onto the crimping ring 4, the boss 13b coming into place in its notch 2f . At this point the pins 14 b are located vis-à-vis the bottom points of the helical ramps 71, 72.

La mise en oeuvre du récipient, qui vient d'être décrit, s'effectue par action de l'utilisateur sur les platines 14c. A l'état de fermeture de la valve, les tétons 14b sont, par l'élasticité des bras 14a, dégagés vers l'extérieur par rapport aux rampes hélicoïdales 71, 72, ce qui permet l'extraction de l'embout de distribution 7 pour nettoyage. Quand l'embout 7 est remis en position après nettoyage, la languette 19 vient s'encliqueter dans l'encoche 20 ; les nervures 18 sont engagées dans les rainures (17, 17a), ce qui empêche toute rotation de la cheminée de distribution par rapport au pot de valve 2. Lorsque l'utilisateur appuie sur les platines 14c et exerce un effort de rotation sur le collier 12, les tétons 14b appuient sur les rampes hélicoïdales 71, 72, ce qui provoque la translation de la cheminée de distribution vers l'intérieur du conteneur 1 ; mais la cheminée de distribution ne peut pas tourner autour de son axe en raison de la coopération des rainures (17, 17a) avec les nervures 18. Au début du mouvement, le léger bossage 13b était logé dans son encoche 2f, ce qui assurait que les tétons se trouvaient au droit du point bas des rampes hélicoïdales 71, 72. La rotation du collier 12 par rapport au conteneur 1 entraîne la descente du clapet 10, la suppression de l'étanchéité entre le joint 11 et le siège de clapet 5 et, par conséquent, la sortie du produit sous l'effet de la pression qui existe dans le conteneur 1. L'ouverture maximum est atteinte quand les tétons 14b arrivent au contact des butées 73. Si par accident, en raison d'un effort trop important exercé par l'utilisateur, les tétons 14b dépassent la butée, ils retombent au droit du point bas de la rampe hélicoïdale sur laquelle ils ne se trouvaient pas initialement, ce qui entraîne immédiatement, sous l'action du ressort 6, la fermeture de la valve : cette disposition permet une sécurité pour la distribution.The implementation of the container, which has just been described, is carried out by action of the user on the plates 14 c . In the state of the valve closure nipples 14 b are, by the elasticity of the arms 14a, released outward relative to the helical ramps 71, 72, which allows the extraction of the tip of distribution 7 for cleaning. When the tip 7 is returned to position after cleaning, the tongue 19 snaps into the notch 20; the ribs 18 are engaged in the grooves (17, 17 a ), which prevents any rotation of chimney distribution with respect to the valve pot 2. When the user presses the plates 14 c and exerts a rotation force on the collar 12, the nipples 14 b based on the helical ramps 71, 72, which causes the translation of the distribution stack towards the interior of the container 1; but the distribution stack can not rotate about its axis because of the cooperation of the grooves (17, 17 a ) with the ribs 18. At the beginning of the movement, the slight boss 13b was housed in its notch 2 f , this which ensured that the nipples were at the right of the low point of the helical ramps 71, 72. The rotation of the collar 12 relative to the container 1 causes the descent of the valve 10, the removal of the seal between the seal 11 and the seat of valve 5 and therefore the output of the product under the effect of the pressure that exists in the container 1. the maximum opening is reached when the pins 14b come into contact with the stops 73. If by accident, due to a too great effort exerted by the user, the pins 14 b exceed the stop, they fall to the right of the low point of the helical ramp on which they were not initially, which leads immediately, under the action of the spring 6, closing of the valve: this arrangement allows a security for the distribution.

L'avantage important du récipient selon l'invention est que la sortie du produit s'effectue avec très peu de perte de charge puisque le seul passage où la section est un peu restreinte est celui qui correspond à la traversée du siège de clapet 5. La perte de charge à la sortie du produit est donc minimum, ce qui permet de distribuer un produit de forte viscosité, tel qu'une crème glacée par exemple.The important advantage of the container according to the invention is that the outlet of the product is carried out with very little loss of load since the only passage where the section is a little restricted is that which corresponds to the passage of the valve seat 5. The pressure drop at the outlet of the product is therefore minimal, which makes it possible to dispense a product of high viscosity, such as an ice cream for example.
