Description

Ensemble verseur à bouchage à vis pour un récipient. Screw cap pourer assembly for a container.
L'invention se rapporte à un ensemble verseur à bouchage à vis pour un récipient fermé de façon hermétique jusqu'à sa première utilisation, comprenant une embase de fixation au récipient, avec une cheminée verseur faisant saillie vers le haut sur ladite embase et comportant un file- tage, un élément de bouchage comportant un filetage pour pouvoir coopérer par vissage avec et obturer la cheminée verseuse, et des moyens pour percer, à la première utilisation, la zone du récipient entourée par l'embase de fixation.The invention relates to a screw-cap pouring assembly for a container hermetically closed until its first use, comprising a base for fixing to the container, with a pouring chimney projecting upwards on said base and comprising a threading, a plugging element comprising a thread in order to be able to cooperate by screwing with and closing the pouring chimney, and means for piercing, on first use, the zone of the container surrounded by the fixing base.
Un ensemble verseur de ce type est connu par exemple par le document EP-A-0328 652, en particulier figure 13. Cet ensemble connu se compose de trois pièces moulées séparément, à savoir un élément verseur, un élément perceur et une capsule de bouchage. Le principal inconvénient de cet ensemble connu consiste dans son coût élevé dû notamment au fait que les trois pièces constitutives de l'ensemble doivent être fabriquées séparément par moulage et être assemblées avant que l'ensemble soit fixé sur un récipient, par exemple par soudage. De plus, cet ensemble connu ne comporte pas de témoin d'inviolabilité apportant à l'utilisateur la preuve visible que l'ensemble verseur à bouchage et donc le récipient équipé de cet ensemble n'a pas fait l'objet d'une ouverture ou tentative d'ouverture frauduleuse.A pouring assembly of this type is known for example from document EP-A-0328 652, in particular FIG. 13. This known assembly consists of three parts molded separately, namely a pouring element, a piercing element and a closure cap. . The main drawback of this known assembly consists in its high cost due in particular to the fact that the three constituent parts of the assembly must be manufactured separately by molding and be assembled before the assembly is fixed to a container, for example by welding. In addition, this known assembly does not include a tamper-evident indicator providing the user with visible proof that the stoppered pouring assembly and therefore the container equipped with this assembly has not been opened or fraudulent opening attempt.
La présente invention vise un ensemble verseur à bouchage à vis qui, tout en étant d'un coût réduit, procure les fonctions des ensembles connus de ce type.The present invention relates to a screw closure pouring assembly which, while being of reduced cost, provides the functions of known assemblies of this type.
L'invention vise par ailleurs un ensemble verseur à bouchage à vis comportant un témoin d'inviolabilité. L'ensemble verseur à bouchage à vis conforme à l'invention pour un récipient fermé de façon hermétique jusqu'à sa première utilisation, comprend une embase de fixation au récipient, avec une cheminée verseuse faisant saillie sur ladite embase et comportant un filetage, un élé- ment de bouchage comportant un filetage pour pouvoir coopérer par vissage avec et obturer la cheminée verseuse, et des moyens pour percer, à la première utilisation, la zone du récipient entourée par l'embase de fixation. La cheminée verseuse de l'embase présente un filetage intérieur et l'élément de bouchage est un bouchon dont au moins la partie supérieure présente un filetage extérieur et qui est moulé d'une seule pièce avec l'embase, la partie filetée du bouchon étant disposée au-dessus de la cheminée. Le bouchon est relié à la cheminée par une zone frangible. Le bouchon présente une hauteur totale supérieure à la hauteur de la cheminée de manière que le récipient se trouve percé par le bouchon au cours du vis- sage de ce dernier dans la cheminée.The invention also relates to a screw-cap pouring assembly comprising a tamper-evident indicator. The screw cap pouring assembly according to the invention for a container hermetically sealed until its first use, comprises a base for fixing to the container, with a pouring chimney projecting from said base and comprising a thread, a closure element comprising a thread in order to be able to cooperate by screwing with and closing the pouring chimney, and means for piercing, on first use, the zone of the container surrounded by the fixing base. The pouring chimney of the base has an internal thread and the plugging element is a plug of which at least the upper part has an external thread and which is molded in one piece with the base, the threaded part of the plug being arranged above the fireplace. The plug is connected to the chimney by a frangible zone. The plug has a total height greater than the height of the chimney so that the container is pierced by the plug during the screwing of the latter into the chimney.
L'ensemble verseur à bouchage à vis suivant l'invention est donc moulé d'une seule pièce. La zone frangible entre le bouchon et la cheminée verseuse constitue le témoin d'inviolabilité, en ce sens que le bouchon est maintenu dans une position prédéterminée par rapport à la cheminée tant que cette zone frangible est intacte. Pour mettre en service l'ensemble verseur, l'utilisateur appuie sur le bouchon pour rompre la zone frangible, puis visse le bouchon dans la cheminée verseuse, de sorte que le bouchon perce la zone du récipient entourée par l'embase de fixation.The screw closure pouring assembly according to the invention is therefore molded in one piece. The frangible zone between the stopper and the pouring chimney constitutes the tamper-evident indicator, in the sense that the stopper is maintained in a predetermined position relative to the chimney as long as this frangible zone is intact. To put the pouring assembly into service, the user presses on the stopper to break the frangible zone, then screws the stopper into the pouring chimney, so that the stopper pierces the area of the container surrounded by the fixing base.
Dans le cadre de l'invention, il est possible, en fonction du maté- riau du récipient et/ou par une conformation (affaiblissement) du récipient dans la zone entourée par l'embase de fixation, de faire en sorte que cette zone du récipient puisse être percée par la simple pression exercée par l'extrémité inférieure du bouchon en fin de vissage.Within the framework of the invention, it is possible, depending on the material of the container and / or by a conformation (weakening) of the container in the area surrounded by the fixing base, to make this area of the container can be pierced by the simple pressure exerted by the lower end of the cap at the end of screwing.
Toutefois, suivant un mode de réalisation préféré, le bouchon présente une partie supérieure filetée et une partie inférieure comprenant au moins une lame ou un tranchant analogue qui perce le récipient par découpage au cours du vissage du bouchon dans la cheminée verseuse.However, according to a preferred embodiment, the stopper has a threaded upper part and a lower part comprising at least one blade or a similar cutting edge which pierces the container by cutting during the screwing of the stopper into the pouring chimney.
La zone frangible reliant le bouchon à la cheminée verseuse peut par exemple comprendre plusieurs picots ou ponts de liaison localisés entre les deux éléments, mais suivant un mode de réalisation préféré, cette zone frangible comprend un voile annulaire de faible épaisseur, ce qui présente l'avantage d'empêcher avec certitude toute pénétration de corps étrangers dans la cheminée verseuse.The frangible zone connecting the plug to the pouring chimney can for example comprise several pins or connecting bridges located between the two elements, but according to a preferred embodiment, this frangible zone includes an annular veil of small thickness, which has the advantage of preventing with certainty any penetration of foreign bodies in the pouring chimney.
De préférence, le bouchon peut comprendre à son extrémité supérieure des moyens de préhension facilitant son vissage et dévissage.Preferably, the plug may comprise at its upper end gripping means facilitating its screwing and unscrewing.
Ces moyens de préhension peuvent par exemple comprendre deux oreilles extérieures opposées.These gripping means can for example comprise two opposite outer ears.
La rigidité de ces oreilles peut être améliorée par le fait que les- dites oreilles sont reliées à l'extrémité supérieure du bouchon par des ren- forts circonférentiels.The rigidity of these ears can be improved by the fact that said ears are connected to the upper end of the stopper by circumferential reinforcements.
Dans le cadre de l'invention, le bouchon peut être réalisé sous la forme d'un godet comprenant une paroi d'extrémité sur laquelle font saillie vers le haut une jupe portant le filetage extérieur et vers le bas la ou les lames ou tranchants analogues, ou sous la forme d'un godet compre- nant une paroi d'extrémité sur laquelle font saillie vers le bas, d'une part, une jupe extérieure portant le filetage extérieur et, d'autre part, une jupe intérieure prolongée vers le bas par la ou les lames ou tranchants analogues.In the context of the invention, the plug can be made in the form of a cup comprising an end wall on which protrude upwards a skirt carrying the external thread and downwards the blade (s) or similar cutting edges , or in the form of a bucket comprising an end wall on which project downwards, on the one hand, an external skirt carrying the external thread and, on the other hand, an internal skirt extended towards the low by the blade or similar cutting edges.
En se référant aux dessins annexés, on va décrire ci-après plus en détail plusieurs modes de réalisation illustratifs et non limitatifs d'un ensemble verseur à bouchage à vis conforme à l'invention; sur les dessins : la figure 1 est une vue en perspective d'un premier mode de réalisation d'un ensemble verseur conforme à l'invention; la figure 2 est une vue de dessus de l'ensemble de la figure 1 ; la figure 3 est une coupe suivant A- A de la figure 2; la figure 4 est une coupe correspondant à celle de la figure 3, après vissage du bouchon dans la cheminée; la figure 5 est une vue en perspective d'un deuxième mode de réalisation de l'ensemble conforme à l'invention; la figure 6 est une vue de dessus de l'ensemble suivant la figure 5 ; la figure 7 est une coupe suivant B-B de la figure 6; la figure 8 est une coupe analogue à celle de la figure 7, le bouchon étant vissé dans la cheminée.Referring to the appended drawings, there will be described below in more detail several illustrative and non-limiting embodiments of a screw-cap pouring assembly according to the invention; in the drawings: FIG. 1 is a perspective view of a first embodiment of a pouring assembly according to the invention; Figure 2 is a top view of the assembly of Figure 1; Figure 3 is a section along A- A of Figure 2; Figure 4 is a section corresponding to that of Figure 3, after screwing the plug into the chimney; Figure 5 is a perspective view of a second embodiment of the assembly according to the invention; Figure 6 is a top view of the assembly according to Figure 5; Figure 7 is a section along B-B of Figure 6; Figure 8 is a section similar to that of Figure 7, the plug being screwed into the chimney.
L'ensemble verseur 1 tel qu'illustré par les figures 1 à 4, est des- tiné à un récipient qui peut être, par exemple, une brique (récipient parai- lelepipédique) formée d'un complexe de carton, d'aluminium et/ou de matière plastique ou un emballage souple en matière plastique du type berlingot. Le récipient dans son ensemble n'est pas représenté, mais on a esquissé sur les figures 1, 3 et 4, la paroi 2 du récipient sur laquelle l'ensemble 1 est fixé.The pouring assembly 1 as illustrated in FIGS. 1 to 4, is intended for a container which can be, for example, a brick (container appears lelepipédique) formed from a complex of cardboard, aluminum and / or plastic or a flexible plastic container of the berlingot type. The container as a whole is not shown, but has been sketched in Figures 1, 3 and 4, the wall 2 of the container on which the assembly 1 is fixed.
L'ensemble 1 comprend essentiellement une embase de fixation 3 et un bouchon 4.The assembly 1 essentially comprises a fixing base 3 and a plug 4.
L'embase de fixation 3 présente une bride 5 annulaire, par laquelle l'embase 3 peut être fixée à la paroi 2 du récipient par soudage, collage ou analogue, et une cheminée verseuse 6 faisant saillie sur la brideThe fixing base 3 has an annular flange 5, by which the base 3 can be fixed to the wall 2 of the container by welding, gluing or the like, and a pouring chimney 6 projecting from the flange
5 vers le haut. La cheminée 6 présente un filetage intérieur 7.5 up. The chimney 6 has an internal thread 7.
Le bouchon 4 qui présente la forme générale d'un godet, comprend un fond 8 sur lequel fait saillie vers le haut une jupe 9 sensiblement cylindrique comportant un filetage extérieur 10. A son extrémité supé- rieure, la jupe 9 du bouchon 4 comporte un rebord extérieur 11. Au niveau du rebord 11 , deux oreilles 12 diamétralement opposées sont formées sur le bouchon 4, chaque oreille 12 comportant une surface de préhension radiale munie de parties 13 en relief améliorant la préhension.The plug 4 which has the general shape of a bucket, comprises a bottom 8 on which protrudes upwards a substantially cylindrical skirt 9 having an external thread 10. At its upper end, the skirt 9 of the plug 4 has a outer rim 11. At the rim 11, two diametrically opposite ears 12 are formed on the plug 4, each ear 12 comprising a radial gripping surface provided with parts 13 in relief improving the gripping.
Tel que cela apparaît sur les figures 1 et 2, les oreilles 12 sont reliées à l'extrémité supérieure du bouchon 4 sur un angle d'environ 90°, grâce à la prévision de renforts circonférentiels 14.As shown in FIGS. 1 and 2, the ears 12 are connected to the upper end of the plug 4 at an angle of approximately 90 °, thanks to the provision of circumferential reinforcements 14.
Le fond 8 du bouchon 4 comporte, sur sa face tournée vers le bas, au moins une lame 15 faisant saillie vers le bas dans une position légèrement décalée vers l'intérieur par rapport au bord du fond 8. Dans l'exemple représenté, la lame 15 comporte un unique tranchant oblique.The bottom 8 of the plug 4 comprises, on its face turned downwards, at least one blade 15 projecting downwards in a position slightly offset inwards relative to the edge of the bottom 8. In the example shown, the blade 15 has a single oblique cutting edge.
L'embase de fixation 3 et le bouchon 4 sont réalisés d'une seule pièce en matière plastique par moulage, le bouchon 4 occupant, par rapport à l'embase 3, la position illustrée par les figures 1 et 3. Dans cette position, le fond 8 du bouchon 4 se trouve à la hauteur de l'extrémité supérieure de la cheminée 5, en étant relié à cette dernière par plusieurs ponts 16 de faible section, répartis sur la circonférence.The fixing base 3 and the plug 4 are made in one piece of plastic by molding, the plug 4 occupying, with respect to the base 3, the position illustrated by FIGS. 1 and 3. In this position, the bottom 8 of the plug 4 is at the height of the upper end of the chimney 5, being connected to the latter by several bridges 16 of small section, distributed over the circumference.
La longueur des lames 15 (parallèlement à l'axe de l'ensemble 1) étant inférieure à la hauteur de la cheminée 6 de l'embase de fixation 3, les lames 15 se trouvent, dans la position suivant les figures 1 et 3, à distance au-dessus de la paroi 2 du récipient sur laquelle est fixée l'embase 3.The length of the blades 15 (parallel to the axis of the assembly 1) being less than the height of the chimney 6 of the fixing base 3, the blades 15 are, in the position according to FIGS. 1 and 3, remote above the wall 2 of the container on which the base 3 is fixed.
Tant que les ponts 16 entre le bouchon 4 et l'embase de fixation 3 sont intacts, le bouchon 4 est maintenu dans cette position haute, ce qui indique et garantit à l'utilisateur que le récipient sur lequel est fixé l'ensemble 1 est intact (témoin d'inviolabilité).As long as the bridges 16 between the plug 4 and the fixing base 3 are intact, the plug 4 is maintained in this high position, which indicates and guarantees to the user that the container on which the assembly 1 is fixed is intact (witness of inviolability).
Pour prélever le contenu du récipient, l'utilisateur exerce une poussée sur le bouchon 4, ce qui provoque la rupture des ponts 16 et permet au bouchon 4 de descendre dans la cheminée 6 jusqu'à ce que son filetage 10 entre en contact avec le filetage 7 de la cheminée 6. Par vissage du bou- chon 4 dans la cheminée 6, il est ensuite possible d'engager le bouchon 4 à fond dans la cheminée 6. Pendant ce mouvement de vissage, les lames 14 percent la paroi 2 de l'emballage, dans sa zone entourée par la bride 5. En fin de vissage, le rebord 11 du bouchon 4 vient porter sur l'extrémité supérieure de la cheminée 6, ce qui assure l'obturation étanche de l'ensemble 1 et donc également du récipient équipé de cet ensemble 1.To take the contents of the container, the user pushes on the plug 4, which breaks the bridges 16 and allows the plug 4 to descend into the chimney 6 until its thread 10 comes into contact with the thread 7 of the chimney 6. By screwing the plug 4 into the chimney 6, it is then possible to engage the plug 4 fully into the chimney 6. During this screwing movement, the blades 14 pierce the wall 2 of the packaging, in its zone surrounded by the flange 5. At the end of screwing, the rim 11 of the plug 4 comes to bear on the upper end of the chimney 6, which ensures the tight sealing of the assembly 1 and therefore also of the container fitted with this set 1.
Le mode de réalisation suivant les figures 5 à 8 reprend les caractéristiques générales de l'ensemble suivant les figures 1 à 4, et ne diffère de ce dernier que sur deux points concernant, le premier la conformation du bouchon 4 et le second la liaison du bouchon 4 avec la cheminée 6 de l'embase de fixation 3, avant la première utilisation.The embodiment according to FIGS. 5 to 8 takes up the general characteristics of the assembly according to FIGS. 1 to 4, and differs from the latter only on two points concerning, the first the conformation of the plug 4 and the second the connection of the plug 4 with the chimney 6 of the fixing base 3, before the first use.
Tel que cela apparaît surtout sur les figures 7 et 8, le bouchon 4 présente la forme générale d'un godet retourné, c'est-à-dire fermé dans le haut par une paroi d'extrémité 17 sur laquelle la jupe 9 portant un filetage extérieur 10 fait saillie vers le bas. Les oreilles 12 font donc saillie vers l'extérieur sur la paroi d'extrémité 17 du bouchon 4 et le rebord 1 1 est prévu au niveau de la paroi d'extrémité 17. Au moins une lame 15 est prévue ici sur une jupe intérieure 18 qui fait saillie vers le bas sur la paroi d'extrémité 17, concentriquement à l'intérieur de la jupe 9.As shown above in FIGS. 7 and 8, the plug 4 has the general shape of an inverted cup, that is to say closed at the top by an end wall 17 on which the skirt 9 carrying a external thread 10 projects downwards. The ears 12 therefore project outwardly from the end wall 17 of the plug 4 and the flange 11 is provided at the end wall 17. At least one blade 15 is provided here on an inner skirt 18 which projects downwards on the end wall 17, concentrically inside the skirt 9.
Par ailleurs, le bouchon 4 est relié à la cheminée 6 de l'embase de fixation 3, non pas par plusieurs ponts 16 comme dans le mode de réalisation des figures 1 à 4, mais par un voile 19 annulaire s'étendant entre l'extrémité supérieure de la cheminée 6 et l'extrémité inférieure de la jupe 9 du bouchon 4, sur tout le pourtour. L'avantage d'un tel voile 19 continu, par rapport à plusieurs ponts 16 localisés, consiste dans le fait qu'il empê- che avec certitude toute pénétration de corps étrangers (poussière, etc.) à l'intérieur de la cheminée 6.Furthermore, the plug 4 is connected to the chimney 6 of the fixing base 3, not by several bridges 16 as in the embodiment of FIGS. 1 to 4, but by an annular web 19 extending between the upper end of the chimney 6 and the lower end of the skirt 9 of the plug 4, around the entire periphery. The advantage of such a continuous veil 19, compared with several localized bridges 16, consists in the fact that it prevents with certainty any penetration of foreign bodies (dust, etc.) to inside the chimney 6.
Il y a lieu de noter que les deux modes de réalisation représentés et décrits n'ont été donnés qu'à titre d'exemples illustratifs et non limitatifs et que de nombreuses modifications et variantes sont possibles dans le cadre de l'invention.It should be noted that the two embodiments shown and described have been given only by way of illustrative and nonlimiting examples and that numerous modifications and variants are possible within the scope of the invention.
Ainsi, il serait possible, au lieu d'utiliser une ou plusieurs lames 15, de donner au bouchon 4 dans son ensemble, en l'occurence à sa jupe 9, une hauteur supérieure à la hauteur de la cheminée 6, de manière qu'en fin de vissage du bouchon 4 dans la cheminée 6, l'extrémité inférieure de la jupe 9 dépasse vers le bas la bride 5 et perce ainsi la paroi 2 du récipient dans la zone entourée par la bride 5.Thus, it would be possible, instead of using one or more blades 15, to give the plug 4 as a whole, in this case to its skirt 9, a height greater than the height of the chimney 6, so that at the end of screwing the plug 4 into the chimney 6, the lower end of the skirt 9 projects downwards from the flange 5 and thus pierces the wall 2 of the container in the area surrounded by the flange 5.
Dans tous les modes de réalisation, mais en particulier en l'absence de lame 15, il peut être avantageux d'affaiblir la paroi 2 du récipient, dans la zone entourée par la bride 5 de l'embase de fixation 3, facili- tant ainsi l'opération de percement de la paroi 2 sous l'effet du vissage du bouchon 4.In all the embodiments, but in particular in the absence of a blade 15, it may be advantageous to weaken the wall 2 of the container, in the area surrounded by the flange 5 of the fixing base 3, facilitating thus the operation of piercing the wall 2 under the effect of the screwing of the plug 4.
Dans tous les cas, le bouchon 4 doit être réalisé et être relié, avant utilisation, à la cheminée 6 de l'embase de fixation 3, de telle manière que le bouchon 4 et l'embase de fixation 3 puissent être réalisés d'une seule pièce par moulage en matière plastique. En particulier, son filetage 10 doit se trouver de préférence au-dessus de l'extrémité supérieure de la cheminée verseuse 6. In all cases, the plug 4 must be produced and be connected, before use, to the chimney 6 of the fixing base 3, in such a way that the plug 4 and the fixing base 3 can be produced in a single piece by plastic molding. In particular, its thread 10 must preferably be located above the upper end of the pouring chimney 6.
