Description

Distributeur pour le soutirage d'un produit fluide contenu dans un récipientDispenser for the withdrawal of a fluid product contained in a container
La présente invention se rapporte à un distributeur pour le soutirage d'un produit fluide contenu dans un récipient.The present invention relates to a dispenser for withdrawing a fluid product contained in a container.
Un tel distributeur est connu par le document WO 80/02 546. Ce distributeur ou robinet destiné plus particulièrement à des récipients du type "bag-in-box" (combinant récipient intérieur souple en forme de poche ou vessie et un récipient extérieur rigide) comprend une pièce fixe formant corps de robinet, comprenant une partie de fixation au récipient qui est prolongée vers l'extérieur du récipient par une partie verseuse de forme générale cylindrique, ouverte à ses deux extrémités axiales et percée d'un orifice latéral de sortie de fluide. Ce distributeur comprend, en outre, une pièce mobile comprenant une partie d'obturation de formule générale cylindrique montée à ajustement serré dans la partie verseuse de la pièce fixe, ouverte à son extrémité axiale intérieure, fermée à son extrémité axiale extérieure et percée d'un orifice latéral de sortie de fluide, et une partie de tête permettant de saisir et de manoeuvrer la pièce mobile depuis l'extérieur. Les deux pièces comprennent par ailleurs des moyens conçus pour définir une première position axiale de la pièce mobile par rapport à la pièce fixe, dans laquelle les orifices latéraux des deux pièces sont décalés axialement de manière à ne pas pouvoir être amenés en coïncidence, donc en communication, quelle que soit la position angulaire de la pièce mobile par rapport à la pièce fixe et des moyens conçus pour définir une seconde position axiale de la pièce mobile par rapport à la pièce fixe, dans laquelle les orifices latéraux des deux pièces peuvent être amenés en coïncidence donc en communication, par rotation de la pièce mobile par rapport à la pièce fixe.Such a dispenser is known from document WO 80/02 546. This dispenser or tap intended more particularly for receptacles of the "bag-in-box" type (combining flexible inner receptacle in the form of a pocket or bladder and a rigid outer receptacle) comprises a fixed part forming a valve body, comprising a part for fixing to the container which is extended towards the outside of the container by a pouring part of generally cylindrical shape, open at its two axial ends and pierced with a lateral outlet outlet from fluid. This dispenser further comprises a movable part comprising a shutter part of general cylindrical formula mounted with a tight fit in the pouring part of the fixed part, open at its internal axial end, closed at its external axial end and pierced with a lateral fluid outlet orifice, and a head part making it possible to grasp and maneuver the moving part from the outside. The two parts also comprise means designed to define a first axial position of the movable part with respect to the fixed part, in which the lateral orifices of the two parts are offset axially so that they cannot be brought into coincidence, therefore in communication, whatever the angular position of the moving part with respect to the fixed part and means designed to define a second axial position of the moving part with respect to the fixed part, into which the lateral orifices of the two parts can be brought coincidentally so in communication, by rotation of the moving part with respect to the fixed part.
Un premier inconvénient de ce distributeur connu sur lequel ladite première position axiale est la position d'extraction et ladite seconde position axiale est la position d'enfoncement de la pièce mobile par rapport à la pièce fixe consiste dans le fait que rien n'est prévu pour maintenir la pièce mobile avec certitude à la première position axiale tant que la pièce mobile n'a pas été manoeuvrée intentionnellement en vue d'une première distribution de fluide. Une distribution soit accidentelle, soit intempestive de fluide ne peut donc pas être exclue avec certitude. Par ailleurs, compte tenu de la structure de ce distributeur connu, la manoeuvre de la partie de tête de la pièce mobile, par rotation, en vue de la distribution du fluide, n'est pas aisée, la partie de tête étant, dans la deuxième position axiale, difficilement accessible en vue de sa rotation. De plus, il n'est pas prévu et il n'est pas possible, sur ce distributeur connu, de ramener la pièce mobile de la seconde position axiale à la première position axiale, c'est-à-dire à la position dans laquelle une rotation de la pièce mobile n'entraîne pas de distribution du fluide. Enfin, ce distributeur connu ne présente pas de moyens dits d'inviolabilité garantissant à l'utilisateur le parfait état du récipient et de son contenu au moment de son achat.A first drawback of this known dispenser on which said first axial position is the extraction position and said second axial position is the position in which the movable part is inserted relative to the fixed part consists in the fact that nothing is provided to hold the moving part with certainty at the first axial position until the moving part has been intentionally operated for a first distribution of fluid. An accidental or untimely distribution of fluid cannot therefore be excluded with certainty. Furthermore, given the structure of this known distributor, the operation of the head part of the movable part, by rotation, for the distribution of the fluid, is not easy, the head part being, in the second axial position, difficult to access for its rotation. In addition, it is not planned and it is not possible, on this known distributor, to bring the moving part from the second axial position to the first axial position, that is to say to the position in which a rotation of the moving part does not cause the fluid to be distributed. Finally, this known distributor does not have so-called inviolability means guaranteeing the user the perfect condition of the container and its contents at the time of purchase.
La présente invention a pour but de fournir un distributeur pour le soutirage d'un produit fluide contenu dans un récipient, distributeur qui remédie aux inconvénients décrits ci-dessus des distributeurs connus.The object of the present invention is to provide a dispenser for withdrawing a fluid product contained in a container, a dispenser which overcomes the drawbacks described above of known dispensers.
Le distributeur objet de l'invention pour le soutirage d'un produit fluide contenu dans un récipient comprend une pièce fixe comprenant une partie de fixation au récipient qui est prolongée vers l'extérieur du récipient par une partie verseuse de forme générale cylindrique, ouverte à ses deux extrémités axiales, et percée d'un orifice latéral de sortie de fluide. Ce distributeur comprend, en outre, une pièce mobile comprenant une partie d'obturation de forme générale cylindrique montée à ajustement serré dans la partie verseuse de la pièce fixe, ouverte à son extrémité axiale intérieure, fermée à son extrémité axiale extérieure et percée d'un orifice latéral de sortie de fluide, et une partie de tête permettant de saisir et de manoeuvrer la pièce mobile depuis l'extérieur. La pièce mobile est montée mobile en translation axiale et en rotation dans la pièce fixe. La pièce fixe et la pièce mobile comprennent des moyens conçus pour définir une première position axiale de la pièce mobile par rapport à la pièce fixe, dans laquelle les orifices latéraux des deux pièces sont décalés axialement de manière à ne pas pouvoir être amenés en coïncidence, quelle que soit la position angulaire de la pièce mobile par rapport à la pièce fixe, et des moyens pour définir une seconde position axiale de la pièce mobile par rapport à la pièce fixe, dans laquelle les orifices latéraux des deux pièces peuvent être amenés en coïncidence par rotation de la pièce mobile. Sur le distributeur suivant l'invention, ladite première position axiale de la pièce mobile est la position d'enfoncement maximale de la pièce mobile dans la pièce fixe et ladite seconde position axiale est la position d'extraction de la pièce mobile de la pièce fixe. La première position axiale de la pièce mobile est définie par une bande d'inviolabilité qui, tant qu'elle n'est pas arrachée, relie la partie de tête de la pièce mobile à la pièce fixe. La seconde position axiale de la pièce mobile est définie par des moyens d'encliquetage conçus pour autoriser une rotation de la pièce mobile dans cette seconde position.The dispenser which is the subject of the invention for withdrawing a fluid product contained in a container comprises a fixed part comprising a part for fixing to the container which is extended towards the outside of the container by a pouring part of generally cylindrical shape, open to its two axial ends, and pierced with a lateral fluid outlet orifice. This dispenser further comprises a movable part comprising a shutter part of generally cylindrical shape mounted with a tight fit in the pouring part of the fixed part, open at its internal axial end, closed at its external axial end and pierced with a lateral fluid outlet orifice, and a head part making it possible to grasp and maneuver the moving part from the outside. The moving part is mounted movable in axial translation and in rotation in the fixed part. The fixed part and the mobile part comprise means designed to define a first axial position of the mobile part with respect to the fixed part, in which the lateral orifices of the two parts are offset axially so that they cannot be brought into coincidence, whatever the angular position of the moving part with respect to the fixed part, and means for defining a second axial position of the moving part with respect to the fixed part, in which the lateral orifices of the two parts can be brought into coincidence by rotation of the moving part. On the dispenser according to the invention, said first axial position of the moving part is the position of maximum insertion of the moving part into the fixed part and said second axial position is the position of extraction of the moving part from the fixed part . The first axial position of the moving part is defined by a tamper-evident band which, as long as it is not torn off, connects the head part of the moving part to the fixed part. The second axial position of the moving part is defined by latching means designed to allow rotation of the moving part in this second position.
De préférence, la bande d'inviolabilité relie la partie de tête de la pièce mobile à un anneau d'accrochage encliqueté sur la pièce fixe.Preferably, the tamper-evident band connects the head part of the moving part to a hooking ring snapped onto the fixed part.
Ainsi, la pièce mobile (partie d'obturation et partie de tête) peut être réalisée d'une seule pièce par moulage avec la bande d'inviolabilité et avec l'anneau d'accrochage, et cet ensemble peut être assemblé avec la pièce fixe moulée à part, la partie d'obturation de la pièce mobile étant emboîtée à fond dans la partie verseuse de la pièce fixe les deux pièces étant solidarisées l'une de l'autre par encliquetage de l'anneau d'accrochage de la pièce mobile derrière un bourrelet extérieur formé sur la pièce fixe.Thus, the moving part (shutter part and head part) can be produced in one piece by molding with the tamper-evident band and with the hooking ring, and this assembly can be assembled with the fixed part. molded apart, the shutter part of the moving part being fully fitted into the pouring part of the fixed part, the two parts being joined to one another by snap-fastening of the hooking ring of the moving part behind an outer bead formed on the fixed part.
Avantageusement, la partie de tête de la pièce mobile présente un rebord extérieur de préhension et la bande d'inviolabilité relie ledit rebord extérieur à la pièce fixe, de préférence à l'anneau d'accrochage coopérant par encliquetage avec la pièce fixe.Advantageously, the head part of the moving part has an external grip rim and the tamper-evident band. connects said outer rim to the fixed part, preferably to the hooking ring cooperating by snap-fastening with the fixed part.
De préférence, le rebord extérieur de la partie de tête, la bande d'inviolabilité et éventuellement la bague d'accrochage de la pièce mobile et la partie de fixation de la pièce fixe présentent sensiblement le même diamètre extérieur, ce qui donne à l'ensemble du distributeur, avant la première ouverture, une forme extérieure générale cylindrique, c'est-à-dire une forme extérieure sensiblement lisse, sans parties saillantes. L'orifice latéral prévu sur la partie verseuse de la pièce fixe, peut avantageusement comporter un bec verseur, de préférence à peu près radial, ce qui permet un versement régulier, quel que soit le débit réglé par un recouvrement plus ou moins important des orifices latéraux des deux pièces du distributeur. Les moyens d'encliquetage définissant la seconde position axiale de la pièce mobile par rapport à la pièce fixe peuvent avantageusement comprendre un bourrelet intérieur sur la pièce fixe et un bourrelet extérieur sur la partie d'obturation de la pièce mobile.Preferably, the outer rim of the head part, the tamper-evident band and possibly the fastening ring of the moving part and the fixing part of the fixed part have substantially the same outside diameter, which gives the assembly of the dispenser, before the first opening, a generally cylindrical outer shape, that is to say a substantially smooth outer shape, without projecting parts. The lateral orifice provided on the pouring part of the fixed part, may advantageously include a pouring spout, preferably approximately radial, which allows a regular pouring, whatever the flow rate adjusted by a more or less significant covering of the orifices. side of the two parts of the dispenser. The latching means defining the second axial position of the moving part with respect to the fixed part may advantageously comprise an internal bead on the fixed part and an external bead on the shutter part of the mobile part.
Le bourrelet intérieur est avantageusement formé sur une jupe prolongeant la partie verseuse de la pièce fixe vers l'intérieur du récipient.The inner bead is advantageously formed on a skirt extending the pouring part of the fixed part towards the interior of the container.
De préférence, la partie d'obturation cylindrique de la pièce mobile présente au moins une échancrure s'étendant depuis l'extrémité intérieure de la partie d'obturation sur une profondeur axiale telle que ladite échancrure soit décalée axialement par rapport à l'orifice latéral de la pièce fixe dans la première position axiale de la pièce mobile et puisse, par rotation de la pièce mobile, dans la deuxième position axiale de cette dernière, être amenée en coïncidence avec l'orifice latéral de la pièce fixe. Suivant un mode de réalisation préféré, deux échancrures diamétralement opposées sont prévues dans la partie d'obturation de la pièce mobile.Preferably, the cylindrical closure part of the movable part has at least one notch extending from the inner end of the closure part to an axial depth such that said notch is offset axially relative to the lateral orifice. of the fixed part in the first axial position of the moving part and can, by rotation of the moving part, in the second axial position of the latter, be brought into coincidence with the lateral orifice of the fixed part. According to a preferred embodiment, two diametrically opposite notches are provided in the closing part of the moving part.
Cela permet, dans la deuxième position axiale de la pièce mobile, d'amener l'une ou l'autre de ces deux échancrures en coïncidence avec l'orifice latéral de la pièce fixe, par un mouvement de rotation de moins de 180° dans un sens ou dans l'autre. De plus, ces deux échancrures donnent à la partie d'obturation, à l'endroit de son bourrelet d'encliquetage, une souplesse favorisant son encliquetage dans la seconde position axiale. Dans le cas où le distributeur est destiné à équiper un récipient contenant un liquide, il peut être avantageux de prévoir, dans la partie verseuse de la pièce fixe, dans une position diamétralement opposée à l'orifice latéral de cette partie, un ou plusieurs trous d'aération qui permettent au fur et à mesure que le liquide s'écoule du récipient, l'entrée d'un volume d'air correspondant à l'intérieur du récipient, évitant ainsi la formation, à l'intérieur du récipient, d'une dépression qui pourrait perturber l'écoulement régulier du liquide.This allows, in the second axial position of the movable part, to bring one or the other of these two notches in coincidence with the lateral orifice of the fixed part, by a movement less than 180 ° in one direction or the other. In addition, these two notches give the closure part, at the place of its latching bead, a flexibility favoring its latching in the second axial position. In the case where the dispenser is intended to equip a container containing a liquid, it may be advantageous to provide, in the pouring part of the fixed part, in a position diametrically opposite to the lateral orifice of this part, one or more holes ventilation that allow as the liquid flows from the container, the entry of a corresponding volume of air inside the container, thus avoiding the formation, inside the container, of '' a depression which could disturb the regular flow of the liquid.
En se référant aux dessins schématiques annexés, on va décrire ci-après plus en détail un mode de réalisation illustratif et non limitatif d'un distributeur conforme à l'invention; sur les dessins : la figure 1 est une vue en perspective d'un bidon équipé d'un distributeur conforme à l'invention; la figure 2 est une vue en élévation frontale du distributeur, avant arrachage de la bande d'inviolabilité; la figure 3 est une coupe suivant III-III de la figure 2; la figure 4 est une vue en perspective éclatée du distributeur de la figure 2, montrant ses deux éléments constitutifs et le goulot du bidon; la figure 5 est une vue analogue à celle de la figure 2 après arrachage de la bande d'inviolabilité et traction sur la pièce mobile; la figure 6 est une coupe suivant NI-NI de la figure 5; la figue 7 est une coupe analogue à celle de la figure 6, après rotation de la pièce mobile de manière que les orifices de sortie de la pièce mobile et de la pièce fixe coïncident. Tel qu'illustré par les dessins, le distributeur 1 conforme à l'invention pour le soutirage de fluide, par exemple de liquide, d'un récipient 2 représenté sur la figure 1 sous la forme d'un bidon en matière plastique, se compose de deux éléments 3 et 4, à savoir un élément 3 destiné à être fixé au goulot 5 du récipient 2 et un élément 4 coopérant avec l'élément 3 pour commander et régler le soutirage du fluide contenu dans le récipient 2.Referring to the appended schematic drawings, there will be described below in more detail an illustrative and nonlimiting embodiment of a dispenser according to the invention; in the drawings: FIG. 1 is a perspective view of a container fitted with a dispenser according to the invention; Figure 2 is a front elevational view of the dispenser, before tearing off the tamper-evident band; Figure 3 is a section along III-III of Figure 2; Figure 4 is an exploded perspective view of the dispenser of Figure 2 showing its two components and the neck of the container; Figure 5 is a view similar to that of Figure 2 after tearing of the tamper-evident band and traction on the moving part; Figure 6 is a section along NI-NI of Figure 5; Fig 7 is a section similar to that of Figure 6, after rotation of the moving part so that the outlet openings of the moving part and the fixed part coincide. As illustrated in the drawings, the dispenser 1 according to the invention for withdrawing fluid, for example liquid, from a container 2 shown in FIG. 1 in the form of a plastic container, consists of of two elements 3 and 4, namely an element 3 intended to be fixed to the neck 5 of the container 2 and an element 4 cooperating with the element 3 to control and regulate the withdrawal of the fluid in container 2.
L'élément 3 comprend une partie 6 de fixation au goulot 5, composée d'une jupe extérieure 7 munie d'un filetage intérieur 8, et d'une jupe intérieure 9 qui coopère avec la surface intérieure du goulot 5 pour assurer l'étanchéité entre l'élément 3 et le goulot 5. La jupe extérieure 7 présente, à distance au-dessus du filetage 8, un décrochement vers l'intérieur, formant un épaulement annulaire 10. Au-dessus de l'épaulement 10, la jupe extérieure 7 comporte un bourrelet annulaire extérieur 1 1 et rejoint ensuite la jupe intérieure 9 par un rebord annulaire intérieur 12 qui s'étend radialement vers l'intérieur au-delà de la jupe intérieure 9.The element 3 comprises a part 6 for fixing to the neck 5, composed of an external skirt 7 provided with an internal thread 8, and an internal skirt 9 which cooperates with the internal surface of the neck 5 to ensure sealing between the element 3 and the neck 5. The outer skirt 7 has, at a distance above the thread 8, an inward recess, forming an annular shoulder 10. Above the shoulder 10, the outer skirt 7 comprises an external annular bead 1 1 and then joins the internal skirt 9 by an internal annular rim 12 which extends radially inwards beyond the internal skirt 9.
La partie de fixation 6 est prolongée, à l'endroit du bord intérieur du rebord 12, axialement vers le haut sur les figures, c'est-à- dire vers l'extérieur du récipient 2, par une partie verseuse 13 de forme générale cylindrique. La partie verseuse 13 comporte latéralement, à distance au-dessus du rebord 12, un orifice d'écoulement de liquide 14 situé à peu près à mi-longueur de la partie 13. L'orifice 14 est entouré d'un bec verseur 15 s'étendant radialement vers l'extérieur. Dans une position diamétralement opposée à l'orifice 14, la partie verseuse 13 présente un orifice d'entrée d'air 16 situé, suivant l'axe de la partie verseuse 13, à peu près au niveau du bord inférieur de l'orifice 14.The fixing part 6 is extended, at the location of the inner edge of the rim 12, axially upwards in the figures, that is to say towards the outside of the container 2, by a pouring part 13 of general shape cylindrical. The pouring part 13 comprises laterally, at a distance above the rim 12, a liquid flow orifice 14 located approximately halfway along the part 13. The orifice 14 is surrounded by a pouring spout 15 s 'extending radially outwards. In a position diametrically opposite to the orifice 14, the pouring part 13 has an air inlet orifice 16 situated, along the axis of the pouring part 13, approximately at the level of the lower edge of the orifice 14 .
Une jupe cylindrique 17 de faible longueur comportant à son extrémité inférieure une rangée circulaire de bourrelets intérieurs 18 s'étend vers le bas à partir du rebord 12, de telle manière que les extrémités intérieures des bourrelets 18 soient situés sensiblement sur le prolongement vers le bas de la surface intérieur de la partie verseuse 13.A short cylindrical skirt 17 having at its lower end a circular row of inner beads 18 extends downward from the rim 12, so that the inner ends of the beads 18 are located substantially on the downward extension of the interior surface of the pouring part 13.
Enfin, un anneau d'inviolabilité 19 comportant un bourrelet intérieur d'accrochage 20 (ou plusieurs ergots intérieurs d'accrochage) est relié par des ponts frangibles 20a au bord inférieur de la jupe extérieure 7 de l'élément 3.Finally, a tamper-evident ring 19 comprising an internal hooking bead 20 (or several internal hooking lugs) is connected by frangible bridges 20a to the lower edge of the external skirt 7 of the element 3.
L'élément 4 comprend une partie d'obturation 21 qui se présente sous la forme d'une jupe cylindrique faisant saillie sur un fond 22 obturant la jupe 21 à son extrémité supérieure. Le fond 22 est prolongé radialement vers l'extérieur au-delà de la jupe 21, sous la forme d'un rebord extérieur annulaire 23. La jupe 21 présente deux échancrures 24 diamétralement opposées s'étendant, depuis l'extrémité inférieure de la jupe, vers le haut sensiblement jusqu'à mi-hauteur de cette dernière. La jupe 21 comporte par ailleurs, à son bord inférieur, un bourrelet extérieur 25 s'étendant sur tout le pourtour de la jupe 21 , sauf à l'endroit des échancrures 24.The element 4 comprises a closure part 21 which is in the form of a cylindrical skirt projecting from a bottom 22 closing the skirt 21 at its upper end. The bottom 22 is extended radially outwards beyond the skirt 21, in the form of an annular outer rim 23. The skirt 21 has two diametrically opposite notches 24 extending, from the lower end of the skirt, upwards substantially to halfway up the latter. The skirt 21 also comprises, at its lower edge, an outer bead 25 extending over the entire periphery of the skirt 21, except at the location of the notches 24.
Une bande d'inviolabilité 26 arrachable, réalisée d'une seule pièce avec le rebord 23 du fond 22, est reliée audit rebord par une zone annulaire 27 de moindre résistance. La bande d'inviolabilité 26 comporte, comme le montrent les figures 1 à 4, une patte de préhension 28 permettant de saisir une extrémité de la bande 26 en vue de son arrachage. A son extrémité inférieure, la bande d'inviolabilité 26 cylindrique est reliée par une zone annulaire 29 de moindre résistance à un anneau d'accrochage 30 muni intérieurement d'un bourrelet annulaire 31 destiné à coopérer par encliquetage avec le bourrelet extérieur 1 1 de la partie de fixation 6 de l'élément 3.A tear-away tamper-evident band 26, made in one piece with the rim 23 of the bottom 22, is connected to said rim by an annular zone 27 of less resistance. The tamper-evident band 26 comprises, as shown in FIGS. 1 to 4, a gripping tab 28 making it possible to grip one end of the band 26 with a view to tearing it off. At its lower end, the cylindrical tamper-evident band 26 is connected by an annular zone 29 of least resistance to a hooking ring 30 provided internally with an annular bead 31 intended to cooperate by snap-fastening with the outer bead 1 1 of the fixing part 6 of element 3.
L'élément 3 est réalisé d'une seule pièce avec la bague d'inviolabilité 19, par moulage en matière plastique. L'élément 4 est réalisé d'une seule pièce avec la bande d'inviolabilité 26 et l'anneau d'accrochage 30, également par moulage en matière thermoplastique.The element 3 is made in one piece with the tamper-evident ring 19, by plastic molding. The element 4 is made in one piece with the tamper-evident band 26 and the attachment ring 30, also by molding in thermoplastic material.
Avant la pose du distributeur 1 formé des deux éléments 3 et 4 sur le goulot 5 du récipient 2, on assemble les deux éléments 3 et 4, en insérant la jupe 21 de l'élément 4 dans la partie verseuse 13 de l'élément 3 jusqu'à ce que, après franchissement du bourrelet intérieurBefore installing the dispenser 1 formed of the two elements 3 and 4 on the neck 5 of the container 2, the two elements 3 and 4 are assembled, by inserting the skirt 21 of the element 4 in the pouring part 13 of the element 3 until after crossing the inner bead
18 de l'élément 3 par le bourrelet extérieur 25 de l'élément 4, l'anneau d'accrochage 31 de l'élément 4 se trouve encliqueté en dessous du bourrelet 10 de l'élément 3, en portant sur l'épaulement 10. Dans cette position qui est visible sur les figures 2 et 3, le bord supérieur des échancrures 24 de la jupe 21 de l'élément 4 est situé plus bas que le bord inférieur de l'orifice 14 de la partie verseuse 13 de l'élément 3.18 of the element 3 by the outer bead 25 of the element 4, the hooking ring 31 of the element 4 is snapped under the bead 10 of the element 3, bearing on the shoulder 10 In this position which is visible in FIGS. 2 and 3, the upper edge of the notches 24 of the skirt 21 of the element 4 is located lower than the lower edge of the orifice 14 of the pouring part 13 of the item 3.
De préférence, cet assemblage des deux éléments 3 et 4 peut être effectué avec un positionnement angulaire bien déterminé de l'élément 4 par rapport à l'élément 3, à savoir de telle manière que la patte d'arrachement 28 de la bande d'inviolabilité 26 se trouve au droit du bec verseur 15 de l'orifice 14 (voir figure 3).Preferably, this assembly of the two elements 3 and 4 can be carried out with a well-determined angular positioning of the element 4 relative to the element 3, namely in such a way that the tear-off tab 28 of the strip of inviolability 26 is found in law the spout 15 of the orifice 14 (see Figure 3).
Pour le montage du distributeur 1 ainsi assemblé à partir des éléments 3 et 4 sur le récipient 2 dont le goulot 5 comporte un filetage extérieur 32 et, en dessous de ce dernier, un bourrelet extérieur d'accrochage 33 et un rebord extérieur d'appui 34, on visse le distributeur 1 sur le goulot 5. La hauteur du rebord 12 de l'élément 3, à l'endroit où ce rebord 12 vient porter sur le bord supérieur du goulot 5, est avantageusement choisie de telle manière que lorsque le distributeur 1 est vissé à fond sur le goulot 5, le bourrelet intérieur 20 de la bague d'inviolabilité 19 étant encliqueté en dessous du bourrelet extérieur 33 du goulot 5, le distributeur 1 occupe une position angulaire bien prédéterminée par rapport au goulot 5.For mounting the dispenser 1 thus assembled from elements 3 and 4 on the container 2, the neck 5 of which has an external thread 32 and, below the latter, an external attachment bead 33 and an external support flange 34, the distributor 1 is screwed onto the neck 5. The height of the rim 12 of the element 3, at the place where this rim 12 comes to bear on the upper edge of the neck 5, is advantageously chosen in such a way that when the dispenser 1 is fully screwed onto the neck 5, the inner bead 20 of the tamper-evident ring 19 being snapped in below the outer bead 33 of the neck 5, the dispenser 1 occupies a well predetermined angular position relative to the neck 5.
Dans le mode de réalisation représenté, le bec verseur 15 qui se trouve en dessous de la patte d'arrachage 28 de la bande d'inviolabilité 26 occupe ainsi une position angulaire telle que lorsque le bidon 2 est couché de telle sorte que, le distributeur 1 soit placé plus bas, le bec verseur 15 soit orienté vers le bas.In the embodiment shown, the spout 15 which is located below the tear-off tab 28 of the tamper-evident band 26 thus occupies an angular position such that when the container 2 is laid down so that the dispenser 1 is placed lower, the spout 15 is oriented downwards.
Pour assurer l'étanchéité entre les deux éléments 3 et 4, il est nécessaire que le diamètre extérieur de la jupe 17 de l'élément 4 et le diamètre intérieur de la partie verseuse 13 de l'élément 3 soient adaptés de manière que la jupe 21 de l'élément 4 soit montée à ajustement serré dans la partie verseuse 13 de l'élément 3.To ensure the seal between the two elements 3 and 4, it is necessary that the outside diameter of the skirt 17 of the element 4 and the inside diameter of the pouring part 13 of the element 3 are adapted so that the skirt 21 of element 4 is fitted tightly in the pouring part 13 of element 3.
Tant que la bande d'inviolabilité 26 n'a pas été arrachée, l'élément 4 occupe la position selon les figures 1 à 3 et tout soutirage, volontaire ou non, est impossible.As long as the tamper-evident band 26 has not been torn off, the element 4 occupies the position according to FIGS. 1 to 3 and any withdrawal, voluntary or not, is impossible.
A la première ouverture, on arrache la bande d'inviolabilité 26 et on tire sur la tête 22 de l'élément 4 pour extraire ce dernier jusqu'à l'encliquetage du bourrelet extérieur 25 de l'élément 4 derrière le bourrelet intérieur 18 de l'élément 3. Dans cette position, aucune des deux échancrures 24 ne se trouve en coïncidence avec l'orifice 14.At the first opening, the tamper-evident band 26 is torn off and the head 22 of the element 4 is pulled to extract the latter until the outer bead 25 of the element 4 clicks behind the inner bead 18 of element 3. In this position, neither of the two notches 24 is in coincidence with the orifice 14.
Ce n'est que par un mouvement de rotation imprimé à l'élément 4, dans un sens ou dans l'autre, qu'il est possible d'amener l'une ou l'autre des deux échancrures 24 en regard de l'orifice 14, ce qui permet un soutirage à un débit réglable par le degré de recouvrement de cette échancrure 24 avec l'orifice 14. En même temps, l'échancrure 24 opposée vient coïncider avec l'orifice 16, permettant ainsi une entrée d'air dans le récipient au fur et à mesure que le fluide contenu dans le récipient s'écoule par l'orifice 14 et le bec verseur 15 (voir figure 7).It is only by a rotational movement imparted to the element 4, in one direction or the other, that it is possible to bring one or the other of the two notches 24 opposite the orifice 14, which allows withdrawal at an adjustable rate by the degree of overlap of this notch 24 with the orifice 14. At the same time, the notch 24 opposite coincides with the orifice 16, thus allowing air to enter the container as the fluid contained in the container flows through the orifice 14 and the spout 15 (see FIG. 7).
Lorsque la quantité requise de fluide a été soutirée, l'utilisateur peut arrêter le soutirage en faisant tourner l'élément 4 de manière que l'échancrure 24 ne coïncide plus avec l'orifice 14, ce qui interrompt le versement. Pour améliorer la sécurité contre un versement intempestif, l'utilisateur peut par ailleurs pousser sur l'élément 4 pour ramener ce dernier en position d'enfoncement selon la figure 3, position dans laquelle, même par rotation de l'élément 4, il n'est pas possible d'amener les échancrures 24 en coïncidence avec l'orifice 14, du fait du décalage axial des échancrures par rapport à l'orifice.When the required quantity of fluid has been withdrawn, the user can stop the withdrawal by rotating the element 4 so that the notch 24 no longer coincides with the orifice 14, which interrupts the pouring. To improve security against an untimely payment, the user can also push on the element 4 to bring the latter into the insertion position according to FIG. 3, position in which, even by rotation of the element 4, there n 'is not possible to bring the notches 24 in coincidence with the orifice 14, due to the axial offset of the notches relative to the orifice.
Il va de soi que le mode de réalisation représenté et décrit n'a été donné qu'à titre d'exemple illustratif et non limitatif et de nombreuses modifications et variantes sont possible dans le cadre de l'invention.It goes without saying that the embodiment shown and described has been given only by way of illustrative and nonlimiting example and numerous modifications and variants are possible within the scope of the invention.
Ainsi, le distributeur 1, au lieu d'être fixé par vissage, pourrait également être fixé par encliquetage sur un goulot conformé en conséquence. Dans ce cas, afin d'assurer un positionnement angulaire correct du distributeur par rapport au récipient, il est possible de prévoir, à la fois sur la partie de fixation 6 de l'élément 3 et sur le goulot 5 du récipient, des moyens de positionnement angulaire coopérant l'un avec l'autre de manière à ne permettre un encliquetage du distributeur sur le goulot que dans la position angulaire recherchée.Thus, the dispenser 1, instead of being fixed by screwing, could also be fixed by snap-fastening on a neck shaped accordingly. In this case, in order to ensure correct angular positioning of the dispenser relative to the container, it is possible to provide, both on the fixing part 6 of the element 3 and on the neck 5 of the container, means of angular positioning cooperating with each other so as to allow the dispenser to snap onto the neck only in the desired angular position.
L'encliquetage définissant la position d'extraction de l'élément mobile 4 pourrait être réalisé par des moyens autres que les bourrelets 18 et 25. La bande d'inviolabilité 26 pourrait coopérer directement avec l'élément 3, de qui supprimerait l'anneau d'accrochage 30.The snap defining the position of extraction of the movable element 4 could be achieved by means other than the beads 18 and 25. The tamper-evident band 26 could cooperate directly with the element 3, which would remove the ring hanging 30.
Le distributeur conforme à l'invention peut utilisé pour 1 soutirage de tout produit fluide pouvant être distribué par versage à partir d'un récipient. Dans le cas de liquides, l'orifice de ventilation 16 peut avantageusement être prévu pour empêcher l'établissement d'une dépression dans le récipient, qui pourrait perturber le soutirage régulier. Le distributeur conforme à l'invention peut également être utilisé par exemple pour le soutirage de poudres ou d'autres produits solides fluides, par exemple sous forme de microbilles. Dans ce cas, un orifice de ventilation peut s'avérer superflu.The dispenser according to the invention can be used for 1 withdrawal of any fluid product which can be dispensed by pouring from a container. In the case of liquids, the ventilation orifice 16 can advantageously be provided to prevent the establishment of a depression in the container, which could disturb regular racking. The dispenser according to the invention can also be used, for example, for drawing off powders or other fluid solid products, for example in the form of microbeads. In this case, a ventilation hole may be superfluous.
Par ailleurs, le distributeur conforme à l'invention pourrait également présenter une forme générale extérieure autre que la forme cylindrique représentée. Furthermore, the dispenser according to the invention could also have a general external shape other than the cylindrical shape shown.
