Abstract

The invention concerns a liquid dispensing tap, consisting essentially of a mount body (1) in the outlet hole of a container for dispensing liquid, made of a rigid material, through a valve or diaphragm (2) sealingly closing an orifice (3) dispensing the liquid, provided with a control member (4) and housed in the part of the body (1) opposite to that of the mounting body in the outlet hole and of means (5) actuating said control member (4). The tap is characterised in that the mount body (1) in the outlet hole of a container for dispensing liquid is produced in double-material by co-injection or co-moulding into one single moulded piece incorporating the means (5) actuating the member (4) controlling the valve or diaphragm (2) sealingly closing the liquid dispensing orifice (3) by spring action, via a deformable elastic membrane made of flexible material with retentive spring action, the rest of the body (1) being made of a rigid material. The invention is more particularly useful for manufacturing taps dispensing liquids contained in small rigid, semirigid or flexible containers, in particular food drinks, having a high barrier capacity to oxygen.

Description

Robinet de distribution de liquides Liquid dispensing valve
La présente invention concerne le domaine de la fabrication de robinets de distribution de liquides contenus dans des petits récipients rigides, semi-rigides ou souples, en particulier de liquides alimentaires, et a pour objet un tel robinet. Actuellement, la distribution de boissons alimentaires, notamment de vins de table, de jus de fruits ou de lait stérilisé ultra-haute température à partir de petits récipients rigides, semi-rigides ou souples, tels que des outres en matière synthétique, s'effectue généralement au moyen de robinets fixés sur la bonde de vidange de ces récipients. A cet effet, on connaît des robinets constitués par un corps de montage dans la bonde d'un récipient et par un piston de libération du liquide chargé par un ressort et guidé dans le corps, le piston agissant sur une membrane d'étanchéité élastique solidaire du corps. Le corps de montage dans la bonde est pourvu d'un emmanchement de fixation coopérant par encliquetage avec la bonde.The present invention relates to the field of manufacture of valves for dispensing liquids contained in small rigid, semi-rigid or flexible containers, in particular of food liquids, and has for its object such a valve. Currently, the distribution of food drinks, in particular table wines, fruit juice or ultra-high temperature sterilized milk from small rigid, semi-rigid or flexible containers, such as plastic bottles, is carried out. generally by means of taps fixed on the drain of these receptacles. To this end, taps are known which consist of a mounting body in the bung of a container and by a piston for releasing the liquid charged by a spring and guided in the body, the piston acting on an elastic sealing membrane integral from the body. The mounting body in the drain is provided with a fastening fitting cooperating by snap-fastening with the drain.
De tels robinets permettent une distribution correcte du liquide et sont parfaitement adaptés, soit à une opération d'embouteillage, soit à une succession de soutirages, que ces derniers soient effectués dans un environnement stérile, tel qu'une chambre stérile sur remplisseuse aseptique, ou non, par exemple pour le remplissage de verres ou de petits récipients, c'est-à-dire pour un usage privé ou en restauration pour de petits débits d'une seule boisson ou d'un seul cru.Such taps allow correct distribution of the liquid and are perfectly suited either to a bottling operation or to a succession of rackings, whether these are carried out in a sterile environment, such as a sterile chamber on an aseptic filler, or no, for example for filling glasses or small containers, that is to say for private use or in catering for small outlets of a single drink or a single vintage.
On connaît également des robinets de distribution de liquides, en particulier de liquides alimentaires aseptiques ou non, à fermeture automatique, qui sont constitués par un corps de montage dans la bonde d'un récipient et par un piston de libération du liquide agissant sur une membrane d'étanchéité élastique solidaire du corps, ces robinets étant pourvus d'un moyen de maintien en position d'ouverture du piston.There are also known taps for dispensing liquids, in particular aseptic food liquids or not, with automatic closure, which are constituted by a mounting body in the bung of a container and by a liquid release piston acting on a membrane. elastic sealing integral with the body, these valves being provided with means for holding the piston in the open position.
Il existe encore d'autres robinets de type à boisseau, dans lesquels le passage du liquide est réalisé par mise en concordance d'ouvertures de passage au moyen d'un levier ou d'une poignée de manœuvre.There are also other valves of the plug type, in which the passage of the liquid is achieved by matching the passage openings by means of a lever or an operating handle.
Tous ces robinets connus permettent de remplir correctement leur fonction essentielle de fermeture étanche d'un récipient avec possibilité de soutirage du liquide contenu. Cependant, compte-tenu du nombre relativement important de leurs pièces constitutives, nécessitant des opérations de montage correspondantes, leur prix de revient est gravement affecté par ces opérations, de sorte que dans le prix de revient de ces robinets celui de la matière formant leurs pièces constitutives ne représente qu'une faible partie.All these known taps make it possible to correctly fulfill their essential function of sealing a container with the possibility of withdrawal of the liquid contained. However, given the relatively large number of their constituent parts, requiring corresponding assembly operations, their cost price is seriously affected by these operations, so that in the cost price of these taps that of the material forming their parts constitutive represents only a small part.
Il est également connu de réaliser un robinet de distribution de liquides comportant un clapet ou une membrane d'obturation étanche d'un orifice de distribution du liquide manœuvré au moyen d'un dispositif de commande faisant partie d'une membrane de fermeture frontale. Un tel robinet présente, cependant l'inconvénient de ne pas permettre de garantir une fermeture parfaite et pérenne de l'orifice de distribution du liquide après les manœuvres. En effet, dans ces robinets, le clapet ou la membrane d'obturation n'est pas guidé et, en outre, le moyen de manœuvre est soumis à une fatigue rapide empêchant la persistance de la mémoire élastique nécessaire pour garantir une fermeture étanche.It is also known to produce a liquid distribution valve comprising a valve or a sealed obturation membrane for a liquid distribution orifice operated by means of a control device forming part of a front closure membrane. Such a tap has, however the drawback of not making it possible to guarantee a perfect and lasting closure of the liquid distribution orifice after the maneuvers. In fact, in these taps, the valve or the shutter membrane is not guided and, moreover, the operating means is subjected to rapid fatigue preventing the persistence of the elastic memory necessary to guarantee a tight closure.
On connaît également, par EP-A-0 213 783, un robinet pour liquides gazeux comprenant un diaphragme manœuvré par l'intermédiaire de deux manettes. Ce robinet est pourvu d'une interface faisant office de diaphragme et agissant sur un piston qui est solidarisé avec ledit diaphragme, ce diaphragme étant actionné par l'intermédiaire de deux manettes s'étendant au-dessus de lui. A cet effet, il est nécessaire de développer une force d'ouverture importante au moyen des manettes, afin de déformer le diaphragme dans le sens d'une ouverture de la valve du robinet. Cette difficulté d'ouverture du diaphragme est due au fait qu'il est réalisé dans la même matière que le corps du robinet, en une seule opération de moulage. Il en résulte que le diaphragme ou dôme, solidarisé avec le piston, n'est pas élastique par nature mais par constitution lors de la fabrication, l'élasticité ou la semi-rigidité nécessaire à sa déformation pour l'actionnement du piston n'étant obtenue que par la prévision de lignes d'affaiblissement circulaires sous forme de rainures.EP-A-0 213 783 also discloses a tap for gaseous liquids comprising a diaphragm operated by means of two levers. This valve is provided with an interface acting as a diaphragm and acting on a piston which is secured to said diaphragm, this diaphragm being actuated by means of two levers extending above it. For this purpose, it is necessary to develop a large opening force by means of the levers, in order to deform the diaphragm in the direction of opening of the valve of the tap. This difficulty in opening the diaphragm is due to the fact that it is made of the same material as the valve body, in a single molding operation. It follows that the diaphragm or dome, secured to the piston, is not elastic by nature but by constitution during manufacture, the elasticity or the semi-rigidity necessary for its deformation for actuation of the piston being obtained only by the provision of circular weakening lines in the form of grooves.
Ainsi, un tel robinet ne peut pas être monostable, c'est-à-dire présenter une élasticité permettant un effet ressort fiable sans contre- pression. En effet, la souplesse du diaphragme ou dôme n'est seule pas suffisante pour assurer des ouvertures et fermetures alternées correctes du robinet et seule une pression du produit renfermé dans le contenant pourvu de ce robinet est susceptible de garantir la fermeture par action sur le piston et pour garantir l'étanchéité.Thus, such a valve cannot be monostable, that is to say have an elasticity allowing a reliable spring effect without back pressure. Indeed, the flexibility of the diaphragm or dome alone is not sufficient to ensure correct alternating openings and closings of the valve and only a pressure of the product contained in the container provided of this valve is likely to guarantee closing by action on the piston and to guarantee sealing.
La présente invention a pour but de pallier les inconvénients des robinets existants et de proposer un robinet à très haute barrière à l'oxygène, facilement manœuvrable, garantissant une fermeture automatique sans action complémentaire du contenu et dont la fabrication des pièces constitutives et leur assemblage peuvent être réalisés de manière simple et rapide, de sorte que leur prix de revient peut être notablement diminué.The object of the present invention is to overcome the drawbacks of existing taps and to propose a tap with a very high oxygen barrier, easily maneuverable, guaranteeing an automatic closing without any additional action of the contents and the manufacture of the constituent parts and their assembly can be carried out in a simple and rapid manner, so that their cost price can be significantly reduced.

Les figures 1 à 8 des dessins annexés représentent un robinet de distribution de liquides, qui est essentiellement constitué par un corps 1 de montage dans la bonde d'un récipient (non représenté) et de distribution du liquide, par un clapet ou une membrane 2 d'obturation étanche d'un orifice 3 de distribution du liquide, muni d'un organe de commande 4 et logé dans la partie du corps 1 opposée à celle de montage dans la bonde et par un moyen 5 d'actionnement dudit organe de commande 4. Conformément à l'invention et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 à 8 des dessins annexés, le corps 1 de montage dans la bonde d'un récipient et de distribution du liquide est réalisé en bi-matière par bi-injection ou comoulage en une pièce moulée unique intégrant le moyen 5 d'actionnement de l'organe 4 de commande du clapet ou de la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide par effet ressort, par l'intermédiaire d'une membrane élastique déformable constituée en une matière souple à effet ressort rémanent, le reste du corps 1 étant constitué en matière rigide. Une telle constitution du reste du corps 1 permet d'assurer une bonne prise en main de ce dernier.Figures 1 to 8 of the accompanying drawings show a liquid distribution valve, which is essentially constituted by a body 1 for mounting in the bung of a container (not shown) and for distributing the liquid, by a valve or a membrane 2 sealing a liquid distribution orifice 3, provided with a control member 4 and housed in the part of the body 1 opposite to that for mounting in the drain and by means 5 for actuating said control member 4. In accordance with the invention and as shown more particularly, by way of example, FIGS. 1 to 8 of the appended drawings, the body 1 for mounting in the bung of a container and for dispensing the liquid is produced in bi -material by bi-injection or co-molding in a single molded part integrating the means 5 for actuating the valve control member 4 or the membrane 2 for sealing the orifice 3 of the liquid distribution orifice 3 by spring effect , through ire of a deformable elastic membrane made of a flexible material with a residual spring effect, the rest of the body 1 being made of rigid material. Such a constitution of the rest of the body 1 ensures good grip of the latter.
Ainsi, le corps 1 et le moyen 5 d'actionnement de l'organe 4 de commande du clapet ou de la membrane 2 d'obturation de l'orifice 3 de distribution de liquide peuvent être réalisés de manière simple et peu onéreuse en une seule opération de moulage, par bi-injection ou comoulage de deux matières présentant des caractéristiques mécaniques différentes. Par ailleurs, l'étanchéité entre le moyen 5 et le corps 1 est parfaitement assurée.Thus, the body 1 and the means 5 for actuating the valve control member 4 or the membrane 2 for closing the orifice 3 for dispensing liquid can be produced in a simple and inexpensive manner in a single molding operation, by bi-injection or co-molding of two materials having different mechanical characteristics. Furthermore, the seal between the means 5 and the body 1 is perfectly ensured.
Selon une caractéristique de l'invention, et comme le montrent plus particulièrement les figures 1 et 3 à 8 des dessins annexés, le clapet ou la membrane 2 d'obturation de l'orifice 3 de distribution de liquide est, de préférence, constitué sous forme d'un piston, dont la tête 2' coopère par forme avec l'orifice 3 de distribution de liquide et qui est chargé par un ressort de compression 2", ledit piston étant muni d'une tige de piston formant l'organe de commande 4 et étant guidé dans un étrier 2'" de montage dans le corps 1, au-dessus de l'orifice de distribution 3.According to a characteristic of the invention, and as shown more particularly in Figures 1 and 3 to 8 of the accompanying drawings, the valve or the membrane 2 for closing the orifice 3 for dispensing liquid is preferably formed under shape of a piston, the head 2 'of which cooperates in shape with the liquid distribution orifice 3 and which is loaded by a compression spring 2 ", said piston being provided with a piston rod forming the control member 4 and being guided in a bracket 2 '"for mounting in the body 1, above the dispensing orifice 3.
Conformément à un premier mode de réalisation, représenté aux figures 1, 3 à 5, 7 et 10 des dessins annexés, le ressort de compression 2" s'appuie directement sur la face arrière du piston constituant le clapet ou la membrane 2 d'obturation de l'orifice 3 de distribution de liquide, entoure la tige de piston formant l'organe de commande 4 ou s'étend de part et d'autre de ladite tige (figure 10) et est relié à son autre extrémité à l'étrier 2'" de montage dans le corps 1, au-dessus de l'orifice de distribution 3. Ainsi, l'ensemble des éléments constitutifs du clapet ou de la membrane 2 d'obturation de l'orifice 3 de distribution de liquide peuvent avantageusement être réalisés par moulage d'un seul tenant. Une telle réalisation du clapet ou de la membrane 2 permet, d'une part, une fabrication simple et à moindre frais et, d'autre part, une limitation des pièces du robinet, de sorte que les opérations de montage sont réduites et que le coût correspondant peut être réduit en conséquence.According to a first embodiment, shown in Figures 1, 3 to 5, 7 and 10 of the accompanying drawings, the compression spring 2 "is supported directly on the rear face of the piston constituting the valve or the shutter membrane 2 of the liquid distribution orifice 3, surrounds the piston rod forming the control member 4 or extends on either side of said rod (Figure 10) and is connected at its other end to the caliper 2 '"for mounting in the body 1, above the dispensing orifice 3. Thus, all of the constituent elements of the valve or of the membrane 2 for closing the orifice 3 of liquid dispensing can advantageously be made by molding in one piece. Such an embodiment of the valve or of the membrane 2 allows, on the one hand, a simple and inexpensive manufacture and, on the other hand, a limitation of the parts of the valve, so that the assembly operations are reduced and the corresponding cost can be reduced accordingly.
Selon le mode de réalisation représenté à la figure 10 des dessins annexés, le ressort de compression 2" est constitué par une paire de lames élastique reliées chacune par une extrémité à l'extrémité de la tige de piston formant l'organe de commande 4 et par son autre extrémité à l'étrier 2'" de montage dans le corps 1, l'ensemble organe de commande 4 - clapet ou membrane 2 - étrier 2'" étant réalisé en une seule pièce de moulage, les lames élastiques formant le ressort de compensation 2" réalisant le guidage de la tige de piston. L'étrier 2'" de montage du clapet ou de la membrane 2 d'obturation de l'orifice 3 de distribution de liquide dans le corps 1, au- dessus de l'orifice de distribution 3, coopère, en position de service, par l'intermédiaire de rebords des extrémités libres de ses ailes, avec des rails de guidage parallèles 6 prévus dans le corps 1, de part et d'autre de l'orifice de distribution 3. Ainsi, il est possible de réaliser un montage aisé du clapet ou de la membrane 2 par simple insertion des rebords des extrémités libres des ailes de l'étrier 2'" dans les rails de guidage parallèles 6 prévus dans le corps 1. A l'arrivée en bout de course de montage de l'étrier 2'", la tête 2' du clapet ou de la membrane 2 se positionne automatiquement sur l'orifice 3 de distribution de liquide et ferme instantanément ce dernier de manière étanche. L'organe de commande 4 formant la tige du piston constituant le clapet ou la membrane 2 présente une partie d'extrémité libre logée dans l'étrier 2'", traversant l'extrémité de ce dernier opposée à l'orifice de distribution 3 du corps 1 et pourvue d'un dispositif 7 de connexion avec l'extrémité correspondante du moyen d'actionnement 5 pénétrant dans le corps 1. Ce dispositif de connexion 7 peut être sous forme d'un trou traversé par l'extrémité de forme correspondante du moyen d'actionnement 5 (figures 1, 3 à 5, 6, 7, 8 et 10). Le dispositif 7 peut également être constitué par deux rainures parallèles, inclinées par rapport à l'axe de l'organe de commande 4, près de son extrémité libre, et coopérant avec l'extrémité correspondante en forme de fourche du moyen d'actionnement 5.According to the embodiment shown in FIG. 10 of the accompanying drawings, the compression spring 2 "is constituted by a pair of elastic blades each connected by one end to the end of the piston rod forming the control member 4 and by its other end to the stirrup 2 '"for mounting in the body 1, the control member 4 - valve or membrane 2 - stirrup 2'" assembly being produced in a single molding, the elastic blades forming the spring 2 "compensation bar guiding the piston rod. The stirrup 2 '"for mounting the valve or the membrane 2 for closing the orifice 3 for dispensing liquid in the body 1, above the dispensing orifice 3, cooperates, in the service position, by means of flanges of the free ends of its wings, with parallel guide rails 6 provided in the body 1, on either side of the dispensing orifice 3. Thus, it is possible to carry out an easy assembly of the valve or of the membrane 2 by simple insertion of the flanges of the free ends of the wings of the stirrup 2 '"in the parallel guide rails 6 provided in the body 1. At the arrival at the end of the mounting stroke of the caliper 2 '", the head 2' of the valve or of the membrane 2 is automatically positioned on the orifice 3 of liquid distribution and instantly closes the latter in a sealed manner. The control member 4 forming the piston rod constituting the valve or the membrane 2 has a free end part housed in the stirrup 2 '", passing through the end of the latter opposite to the distribution orifice 3 of the body 1 and provided with a device 7 for connection with the corresponding end of the actuating means 5 penetrating into the body 1. This connection device 7 may be in the form of a hole through which the correspondingly shaped end of the actuating means 5 (Figures 1, 3 to 5, 6, 7, 8 and 10.) The device 7 can also be constituted by two parallel grooves, inclined relative to the axis of the control member 4, close of its free end, and cooperating with the corresponding fork-shaped end of the actuating means 5.
Le moyen 5 d'actionnement de l'organe 4 de commande du clapet ou de la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide est avantageusement constitué par une tige de manœuvre 5' s'étendant dans le corps 1, parallèlement à l'axe longitudinal de ce dernier, réalisée en une matière rigide, coopérant par une extrémité, à l'intérieur dudit corps 1, avec le dispositif de connexion 7 de l'extrémité correspondante de l'organe de commande 4, et par un bouton de commande 5" formant la membrane élastique déformable, qui est avantageusement réalisé en une matière souple à effet ressort rémanent, bi-injectée ou comoulée avec le corps 1 et avec la tige de manœuvre 5' et relié, d'une part, de manière étanche avec l'extrémité du corps 1 opposée à celle de montage dans la bonde d'un récipient et, d'autre part, avec l'extrémité de la tige de manœuvre 5' opposée au clapet ou à la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide. La conformation du bouton de commande 5" en une matière souple à effet ressort rémanent permet la manœuvre aisée de la tige 5', tout en assurant une étanchéité parfaite du robinet.The means 5 for actuating the valve control member 4 or the diaphragm 2 for sealing off the orifice 3 for distributing the liquid is advantageously constituted by an operating rod 5 ′ extending in the body 1 , parallel to the longitudinal axis of the latter, made of a rigid material, cooperating at one end, inside said body 1, with the connection device 7 of the corresponding end of the control member 4, and by a control button 5 "forming the deformable elastic membrane, which is advantageously made of a flexible material with a residual spring effect, bi-injected or co-molded with the body 1 and with the operating rod 5 'and connected, on the one hand , in a sealed manner with the end of the body 1 opposite to that of mounting in the bung of a container and, on the other hand, with the end of the operating rod 5 'opposite the valve or the membrane 2 d sealing of orifice 3 of distributio n of the liquid. The shape of the control button 5 "in a flexible material with a residual spring effect allows easy operation of the rod 5 ′, while ensuring perfect sealing of the tap.
L'extrémité libre de la tige de manœuvre 5' est avantageusement en forme de coin et coopère avec une paroi de pente correspondante du dispositif de connexion 7 de l'extrémité correspondante de l'organe de commande 4. Ainsi, par pression sur le bouton de commande 5", la tige de manœuvre 5' pénètre dans le logement formant le dispositif de connexion 7 et, par coopération de son extrémité en forme de coin avec la paroi en pente correspondante dudit logement, la tige 5' exerce une poussée sur l'extrémité correspondante de l'organe 4 de commande du clapet ou de la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide, de sorte que ledit clapet ou membrane 2 est soulevé de son siège sur l'orifice de distribution 3 et libère le passage du liquide.The free end of the operating rod 5 ′ is advantageously wedge-shaped and cooperates with a wall of corresponding slope of the connection device 7 of the corresponding end of the control member 4. Thus, by pressing the button 5 "control, the operating rod 5 'enters the housing forming the connection device 7 and, by cooperation of its wedge-shaped end with the corresponding sloping wall of said housing, the rod 5' pushes on the 'corresponding end of the valve control member 4 or membrane 2 for sealing the orifice 3 of the liquid distribution, so that said valve or membrane 2 is lifted from its seat on the dispensing orifice 3 and frees the passage of the liquid.
La figure 5 des dessins annexés représente une variante de réalisation de l'invention, dans laquelle le bouton de commande 5" du moyen 5 d'actionnement de l'organe 4 de commande du clapet ou de la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide est chargé par un ressort de rappel 5'" avantageusement monté sur la tige de manœuvre 5' et solidaire, du côté opposé au bouton de commande 5", de l'étrier 2'" de montage du clapet ou de la membrane 2 d'obturation de l'orifice 3 de distribution de liquide dans le corps 1. La prévision d'un tel ressort de rappel 5'" permet d'optimiser la manœuvre du bouton de commande 5" en favorisant son retour en position de repos après chaque manœuvre du clapet ou de la membrane 2, de sorte que l'action de fermeture dudit clapet ou membrane 2 par le ressort de compression 2" est optimisée et qu'une obturation parfaitement étanche de l'orifice 3 de distribution de liquide peut être obtenue.Figure 5 of the accompanying drawings shows an alternative embodiment of the invention, in which the control button 5 "of the means 5 for actuating the valve control member 4 or the membrane 2 for sealing the shutter orifice 3 for distributing the liquid is loaded by a return spring 5 '"advantageously mounted on the operating rod 5' and secured, on the side opposite to the control button 5", to the bracket 2 "for mounting the valve or of the diaphragm 2 for closing the orifice 3 for distributing liquid in the body 1. The provision of such a return spring 5 ′ "makes it possible to optimize the operation of the control button 5" by promoting its return in the rest position after each maneuver of the valve or membrane 2, so that the action of closing said valve or membrane 2 by the compression spring 2 "is optimized and that a perfectly sealed obturation of the orifice 3 of liquid distribution can be obtained.
La figure 6 des dessins annexés représente une autre variante de réalisation de l'invention, dans laquelle le ressort de compression 2" est constitué sous forme d'une lame recourbée, reliée par une extrémité à l'extrémité supérieure de l'étrier 2'", élastiquement déformable et s'appuyant par son extrémité libre sur l'extrémité de la tige de piston formant l'organe de commande 4 du clapet ou de la membrane 2. Dans ce mode de réalisation, l'extrémité de la lame s'appuyant sur l'extrémité de la tige de piston formant l'organe de commande 4 peut également être solidaire de cette extrémité, de sorte que l'ensemble des éléments constitutifs du clapet ou de la membrane 2 peuvent être réalisés par moulage d'un seul tenant.Figure 6 of the accompanying drawings shows another alternative embodiment of the invention, in which the compression spring 2 "is formed in the form of a curved blade, connected by one end to the upper end of the bracket 2 ' ", elastically deformable and supported by its free end on the end of the piston rod forming the control member 4 of the valve or of the membrane 2. In this embodiment, the end of the blade s' pressing on the end of the piston rod forming the control member 4 can also be integral with this end, so that all of the constituent elements of the valve or of the membrane 2 can be produced by molding in one holding.
La figure 7 des dessins annexés représente une autre variante de réalisation de l'invention, dans laquelle le clapet ou la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide est doublé par un deuxième clapet ou membrane 12 d'obturation étanche d'un orifice 13 d'entrée d'air, ce clapet ou membrane 12 étant manœuvré par l'intermédiaire du moyen 5 d'actionnement de l'organe 4 de commande dudit clapet ou de ladite membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide. La constitution de ce deuxième clapet ou membrane 12 d'obturation étanche d'un orifice 13 d'entrée d'air peut être identique à celle du clapet ou de la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide, la section de l'ouverture de l'orifice 13 étant, de préférence, inférieure à celle de l'orifice 3 de distribution du liquide. Un robinet ainsi réalisé est particulièrement adapté à un montage sur un conteneur rigide, dont le robinet nécessite une prise d'air. Ce robinet permet une vidange correcte de l'emballage, sans à-coup, le liquide qui s'écoule étant remplacé par un effet de siphonnage par l'air entrant à travers l'orifice 13, ce suite à la manœuvre unique du moyen 5.Figure 7 of the accompanying drawings shows another alternative embodiment of the invention, in which the valve or diaphragm 2 for sealing off the liquid distribution orifice 3 is doubled by a second valve or diaphragm 12 for sealing sealed from an air inlet orifice 13, this valve or membrane 12 being operated by means 5 of actuation of the member 4 for controlling said valve or said membrane 2 for sealing the air orifice 3 for dispensing the liquid. The constitution of this second valve or membrane 12 for sealing off an air inlet orifice 13 may be identical to that of the valve or membrane 2 for sealing off the orifice 3 for distributing the liquid, the section of the opening of the orifice 13 preferably being lower than that of the liquid distribution orifice 3. A valve thus produced is particularly suitable for mounting on a rigid container, the valve of which requires an air intake. This tap allows correct emptying of the packaging, smoothly, the flowing liquid being replaced by a siphoning effect by the air entering through the orifice 13, this following the unique operation of the means 5 .
Les clapets ou membranes 2 et 12, respectivement d'obturation étanche de l'orifice 3 de distribution du liquide et d'obturation étanche de l'orifice 13 d'entrée d'air peuvent avantageusement être réalisés sous forme d'une pièce de moulage unique. Ainsi, ces clapets ou membranes 2 et 12 peuvent être montés en une opération unique, rapide et simple, dans le corps 1.The valves or membranes 2 and 12, respectively for sealing the orifice 3 for distributing the liquid and for sealing the orifice 13 for the air inlet can advantageously be produced in the form of a molding part. unique. Thus, these valves or membranes 2 and 12 can be mounted in a single, quick and simple operation, in the body 1.
Les figures 8 et 9 des dessins annexés représentent une autre variante de réalisation de l'invention, dans laquelle la tige de manœuvre 5' constituant le moyen 5 d'actionnement de l'organe 4 de commande du clapet ou de la membrane 2 d'obturation étanche de l'orifice 3 de distribution du liquide est avantageusement reliée à l'extrémité correspondante du corps 1 par l'intermédiaire de ponts flexibles 18 réalisés dans la même matière que ladite tige 5' et que le corps 1 et surmoulés par la matière souple constitutive de la membrane formant le bouton de commande 5", au cours du comoulage ou de la bi-injection de l'ensemble. La réalisation des ponts flexibles 18 dans la même matière rigide que le corps 1 et la tige 5' permet le moulage simultané de ces ponts et de la tige 5' lors de la première partie du comoulage ou de la bi-injection et un centrage parfait de ladite tige 5' lors du moulage de la membrane flexible formant le bouton de commande 5", au cours de la deuxième partie dudit comoulage ou de ladite bi-injection. Ainsi, le moule du robinet peut être simplifié, la tige de manœuvre 5' étant reliée au corps 1 et ne nécessitant pas un maintien spécifique pendant la deuxième partie de l'opération de comoulage ou de bi-injection. Selon une autre caractéristique de l'invention et comme le montrent les figures 1 à 3 et 5 des dessins annexés, le robinet peut être pourvu, en outre, d'un dispositif d'inviolabilité destructible 14, solidarisé avec le corps 1 et se présentant sous forme d'une collerette arrachable entourant la partie du moyen d'actionnement 5 et, éventuellement, la butée 11 en saillie sur le corps 1. Ainsi, une action sur le moyen d'actionnement 5 ne peut être effectuée qu'après arrachement préalable du dispositif d'inviolabilité destructible 14. Conformément à une autre caractéristique de l'invention, l'inviolabilité ainsi obtenue peut être complétée par la prévision sur le dispositif d'inviolabilité destructible 14 d'un opercule déchirable et thermoscellable 15 fermant ledit dispositif d'inviolabilité 14 au-dessus du moyen d'actionnement 5 et, éventuellement, de la butée 8, cet opercule 15 pouvant avantageusement être pourvu d'un timbre de fiscalisation et pouvant recouvrir, en outre, le ou les orifices 3 et 13. Il en résulte qu'à la première utilisation du robinet, lors de la libération du moyen d'actionnement 5 par arrachage du dispositif d'inviolabilité destructible 14, le timbre de fiscalisation apposé sur l'opercule 15 est détruit et que toute fraude par réutilisation est impossible.Figures 8 and 9 of the accompanying drawings show another alternative embodiment of the invention, in which the operating rod 5 'constituting the means 5 for actuating the valve control member 4 or the membrane 2 of tight sealing of the liquid distribution orifice 3 is advantageously connected to the corresponding end of the body 1 by means of flexible bridges 18 made of the same material as said rod 5 'and as the body 1 and overmolded by the material flexible component of the membrane forming the control button 5 ", during co-molding or bi-injection of the assembly. The realization of the flexible bridges 18 in the same rigid material as the body 1 and the rod 5 'allows the simultaneous molding of these bridges and of the rod 5 'during the first part of the co-molding or of the bi-injection and perfect centering of the said rod 5' during the molding of the flexible membrane forming the control button 5 ", during of the second me part of said co-molding or said bi-injection. Thus, the tap mold can be simplified, the operating rod 5 ′ being connected to the body 1 and not requiring specific support during the second part of the co-molding or bi-injection operation. According to another characteristic of the invention and as shown in Figures 1 to 3 and 5 of the accompanying drawings, the valve can be provided, in addition, with a destructible tamper-evident device 14, secured to the body 1 and having in the form of a removable collar surrounding the part of the actuating means 5 and, optionally, the stop 11 projecting from the body 1. Thus, an action on the actuating means 5 can only be carried out after prior tearing of the destructible inviolability device 14. In accordance with another characteristic of the invention, the inviolability thus obtained can be supplemented by the provision on the destructible inviolability device 14 of a tearable and heat-sealable cover 15 closing said inviolability device 14 above the means d actuation 5 and, optionally, of the stop 8, this cover 15 which can advantageously be provided with a tax stamp and which can cover, in addition, the orifice (s) 3 and 13. As a result, the first use of the tap, when the actuating means 5 are released by tearing off the destructible inviolability device 14, the tax stamp affixed to the cover 15 is destroyed and that any fraud by reuse is impossible.
De préférence, l'opercule déchirable 15 peut être réalisé d'une seule pièce avec le dispositif d'inviolabilité destructible 14, en un matériau identique ou en un matériau différent, et peut simplement présenter une épaisseur moindre que celle dudit dispositif d'inviolabilité destructible 14. Il résulte de ce mode de réalisation que le robinet est inviolable pendant le transport et le stockage. Ainsi, la sécurité indispensable, notamment pour le conditionnement de liquides alimentaires aseptiques, est assurée et une utilisation délictueuse est instantanément détectée. Enfin, selon une autre caractéristique de l'invention et comme le montrent plus particulièrement les figures 1 à 3 des dessins annexés, le corps 1 de montage dans la bonde d'un récipient et de distribution du liquide est avantageusement relié à une partie de base 16, formant goulot et destinée à la liaison avec un conteneur, par une liaison initiale par l'intermédiaire d'un moyen physique destructible 17, la partie du corps 1 reliée à la partie de base 16 formant goulot étant emboîtable et verrouillable en position d'emboîtement définitif dans ladite partie de base 16 formant goulot après destruction du moyen physique 17. Ainsi, l'ensemble corps 1 - partie de base 16 peut être fixé de manière définitive et aseptique, par soudage de ladite partie de base 16 sur ou dans une ouverture correspondante d'un conteneur, le corps 1 étant arraché de la partie de base 16 pour le remplissage dudit conteneur, puis emboîté et verrouillé dans ladite partie 16 après remplissage.Preferably, the tearable lid 15 can be made in one piece with the destructible tamper-evident device 14, in an identical material or in a different material, and may simply have a thickness less than that of said destructible tamper-evident device 14. It follows from this embodiment that the tap is inviolable during transport and storage. Thus, the essential security, in particular for the packaging of aseptic food liquids, is ensured and criminal use is instantly detected. Finally, according to another characteristic of the invention and as shown more particularly in Figures 1 to 3 of the accompanying drawings, the body 1 for mounting in the bung of a container and for dispensing the liquid is advantageously connected to a base part 16, forming a neck and intended for the connection with a container, by an initial connection by means of a destructible physical means 17, the part of the body 1 connected to the base part 16 forming the neck being nestable and lockable in position d definitive fitting into said base part 16 forming a neck after destruction of the physical means 17. Thus, the body 1 - base part 16 assembly can be fixed definitively and aseptically, by welding of said base part 16 on or in a corresponding opening of a container, the body 1 being torn from the base part 16 for filling said container, then fitted and locked in said part 16 after filling age.
Le moyen physique destructible 17 est, de préférence, sous forme d'une bande fragilisée constituée dans la même matière que celle constitutive de la partie de base 16 et du corps 1. Il résulte de cette constitution la possibilité de réaliser le corps 1 et la partie de base 16, formant goulot, en une seule opération de moulage dans un moule unique, de sorte que la pièce monobloc obtenue peut être d'un coût nettement plus faible que celui des deux pièces utilisées à ce jour.The destructible physical means 17 is preferably in the form of a weakened strip made of the same material as that constituting the base part 16 and of the body 1.
