Abstract

The inner face (4a) of the bottom (4) of the closure (1) comprises at least one tooth (4d). The top of the annular crown (9) of the pourer (2), which is applied against the bottom (4) of the closure (1), is provided with at least one notch (9a). The inner wall of the skirt (10) of the pourer (2), which is intended to surround the neck, comprises a projection (10b). The end (11a) of the neck comprises an axial groove (11d) in which the projection (10b) of the pourer (2) engages when the closure (1) is screwed onto the neck (11) and the tooth (4b) of this closure (1) comes up against the notch (9a) of the pourer (2) in order to drive it in rotation. The angular retention exerted on the pourer (2) by the projection (10b)/groove (11d) assembly is greater than that produced by the support (4b)/notch (9a), so that, once the projection is arranged in the groove, the pourer (2) remains angularly fixed. <IMAGE>

Description

La présente invention est relative à des perfectionnements apportés aux systèmes d'obturation comportant un bec verseur.The present invention relates to improvements made to closure systems comprising a pouring spout.

Dans les dispositifs du genre en question, il est nécessaire, lorsqu'on a affaire à un récipient pourvu d'une poignée, d'orienter le bec verseur de manière qu'il se trouve diamétralement opposé à ladite poignée. Une telle opération est bien entendu longue et fastidieuse, ce qui est un inconvé­nient majeur lorsqu'on a affaire à un emballage de produit de grande dis­tribution.In devices of the kind in question, it is necessary, when dealing with a container provided with a handle, to orient the spout so that it is diametrically opposite to said handle. Such an operation is of course long and tedious, which is a major drawback when dealing with a packaging product of mass distribution.

De manière générale, on prévoit que les becs verseurs modernes se trouvent à l'intérieur du goulot du récipient de manière qu'ils puissent être placés dans le bouchon à vis avant la mise en place de celui-ci sur le goulot du récipient. Dans ces conditions, il était pratiquement impossible jusqu'à présent de pouvoir orienter automatiquement le bec verseur, de telle sorte que c'est l'utilisateur qui, lors du déversement du produit, était obligé d'orienter le verseur afin qu'il soit en opposition par rapport à la poignée.In general, provision is made for modern pouring spouts to be inside the neck of the container so that they can be placed in the screw cap before the latter is placed on the neck of the container. In these conditions, it has been practically impossible until now to be able to automatically orient the pouring spout, so that it is the user who, when spilling the product, was obliged to orient the pourer so that it is in opposition to the handle.

Il est également de plus en plus courant de munir les bouchons destinés à être placés sur des récipients contenant des produits nocifs, de systèmes rendant très difficile le dévissage par des enfants en bas âge, de manière à pratiquement interdire tout accès aux produits nocifs contenus dans des récipients ainsi obturés.It is also more and more common to equip the caps intended to be placed on receptacles containing harmful products, with systems making very difficult the unscrewing by young children, so as to practically prohibit any access to the harmful products contained in containers thus closed.

Les perfectionnements qui font l'object de la présente invention visent à atteindre les deux buts ci-dessus mentionnés, c'est-à-dire d'une part assu­rer l'orientation automatique du verseur par rapport au récipient et d'au­tre part réaliser un bouchon à dévissage difficile pour des jeunes enfants.The improvements which are the object of the present invention aim to achieve the two goals mentioned above, that is to say on the one hand to ensure the automatic orientation of the spout relative to the container and on the other hand to achieve a difficult to unscrew cap for young children.

A cet effet, le fond intérieur du bouchon comporte une dent et le dessus de la partie annulaire du verseur appliquée contre le fond intérieur est pour­vu d'un cran, tandis que la paroi interne de la jupe dudit verseur qui est destinée à entourer le bout lisse du goulot comporte une saillie propre à venir coopérer avec une rainure axiale (ou vice-versa) dudit bout lorsqu'on visse le bouchon sur le goulot et que la dent du bouchon bute contre le cran du verseur pour l'entraîner en rotation, la retenue angulaire exercée sur le verseur par l'assemblage saillie rainure étant plus importante que celle engendrée par l'appui dent-cran de manière qu'une fois la saillie engagée dans la rainure, le verseur soit immobilisé en rotation tandis que la dent du bouchon n'est plus stoppée par le cran.To this end, the inner bottom of the stopper has a tooth and the top of the annular part of the pourer applied against the inner bottom is provided with a notch, while the inner wall of the skirt of said pourer which is intended to surround the end. smooth of the neck has a clean projection to cooperate with an axial groove (or vice versa) of said end when the cap is screwed on the neck and the tooth of the cap abuts against the notch of the pourer to drive it in rotation, the angular restraint exerted on the pourer by the groove projection assembly being greater than that generated by the tooth-notch support so that once the projection engaged in the groove, the pourer is immobilized in rotation while the plug tooth is no longer stopped by the notch.

Suivant un mode d'exécution préféré, la jupe extérieure du bouchon est pourvue sur sa face interne d'au moins un ressaut propre à coopérer avec au moins un redan ménagé sur le flacon afin d'éviter le dévissage du bouchon, les zones dudit flacon situées de part et d'autre de son diamètre orienté à 90° par rapport à son redan étant aplaties afin qu'une pression centripète sur la jupe extérieure prévue élastique au niveau des deux aplatissements du flacon, provoque le dégagement du ressaut par rapport au redan.According to a preferred embodiment, the outer skirt of the stopper is provided on its internal face with at least one projection capable of cooperating with at least one step formed on the bottle in order to avoid unscrewing the stopper, the areas of said bottle located on either side of its diameter oriented at 90 ° relative to its step being flattened so that a centripetal pressure on the outer skirt provided elastic at the two flattenings of the bottle, causes the release of the projection relative to the step .

La combinaison suivant l'invention est essentiellement constituée d'un bouchon ou obturateur 1, d'un bec verseur 2, et d'un récipient ou flacon 3.The combination according to the invention essentially consists of a plug or obturator 1, a pouring spout 2, and a container or bottle 3.

Le bouchon 1 est constitué, comme usuellement, par un fond 4 à partir de la face intérieure duquel part un manchon central 5 prévu taraudé et qui est entouré par une jupe extérieure 6 plus longue que le manchon 5.The plug 1 is constituted, as usual, by a bottom 4 from the inner face from which a central sleeve 5 provided with a thread and which is surrounded by an outer skirt 6 longer than the sleeve 5 leaves.

Conformément à l'invention, la face intérieure 4a du fond 4 est pourvue de deux dents 4b diamétralement opposées, réalisées sous la forme d'une dent de rochet, qui présente une face avant perpendiculaire au fond 4. La face intérieure de la jupe 6 est encore pourvue d'un ressaut axial 6a comme on l'expliquera mieux plus loin.According to the invention, the inner face 4 a of the bottom 4 is provided with two diametrically opposite teeth 4 b , produced in the form of a ratchet tooth, which has a front face perpendicular to the bottom 4. The inner face of the skirt 6 is also provided with an axial projection 6 a as will be explained better below.

Le bec verseur 2 comprend un bec cylindrique 7 relié par une cheminée tron­conique 8 à une couronne 9 à de la périphérie de laquelle part une jupe 10 parallèle au bec 7. La face interne de la jupe 10 est pourvue d'un cordon 10a destiné à s'encliqueter dans une gorge correspondante du goulot du ré­cipient 3 comme on l'expliquera mieux plus loin. En vis-à-vis de la partie de déversement 7a du bec 7, la jupe 10 est pourvue encore sur sa face inté­rieure d'une saillie longitudinale 10b dont le rôle sera expliqué ci-après.The pouring spout 2 comprises a cylindrical nozzle 7 connected by a frustoconical chimney 8 to a ring 9 to the periphery from which a skirt 10 parallel to the spout 7. The inner face of the skirt 10 is provided with a strip 10 destined to snap into a corresponding groove in the neck of the container 3 as will be better explained below. Opposite the pouring part 7 a of the spout 7, the skirt 10 is also provided on its inner face with a longitudinal projection 10 b , the role of which will be explained below.

On observe que le dessus de la couronne annulaire 9 comprend deux crans 9a disposés de manière diamétralement opposées.It is observed that the top of the annular ring 9 comprises two notches 9 a arranged diametrically opposite.

Le récipient 3 qui est réalisé sous la forme d'un flacon est pourvu d'un goulot 11 dont le bout 11a est lisse, c'est-à-dire que le filetage 11b du goulot part en dessous de ce bout 11a. Dans ce dernier est ménagée une gorge 11c apte à recevoir le cordon 10a. Ce bout comporte encore une rai­nure longitudinale 11d destinée à recevoir la saillie 10b du verseur 2.The container 3 which is produced in the form of a bottle is provided with a neck 11 the end 11 a of which is smooth, that is to say that the thread 11 b of the neck leaves below this end 11 a . In the latter is formed a groove 11 c capable of receiving the cord 10 a . This end also has a longitudinal groove 11 d intended to receive the projection 10 b of the pourer 2.

En dessous du goulot 11, le flacon 3 comporte un col 12 de forme ovale et dont l'une des deux parties aplaties est pourvue d'un redan 12a. Le flacon 3 est pourvu d'une poignée 13 orientée de manière diamétralement opposée par rapport à la rainure 11d de son goulot.Below the neck 11, the bottle 3 has a neck 12 of oval shape and one of the two flattened parts of which is provided with a step 12 a . The bottle 3 is provided with a handle 13 oriented diametrically opposite with respect to the groove 11 d of its neck.

Le fonctionnement découle des explications qui précèdent :The operation follows from the above explanations:

Le verseur 2 est d'abord automatiquement engagé à l'intérieur du manchon 5, sa jupe 10 s'engageant sans jeu notable à l'intérieur du filetage de ce manchon. La couronne 9 du verseur vient donc se disposer très près de l'in­térieur 4a du fond 4 du bouchon 1. Elle en est distante de l'épaisseur de ses crans 9a qui sont de même hauteur que celle des dents 4b. Celles-ci reposent donc contre la couronne 9 et les crans 9a de cette dernière contre la face 4a du fond 4.The pourer 2 is first automatically engaged inside the sleeve 5, its skirt 10 engaging without significant play inside the thread of this sleeve. The crown 9 of the pourer therefore comes to be placed very close to the interior 4 a of the bottom 4 of the plug 1. It is distant from it by the thickness of its notches 9 a which are the same height as that of the teeth 4 b . These therefore rest against the crown 9 and the notches 9 a of the latter against the face 4 a of the bottom 4.

Comme à l'accoutumée, l'ensemble du bouchon 1 et de son bec verseur 2 est placé dans un distributeur automatique destiné à l'amener en vis-à-vis du goulot 11 d'un flacon 13. Bien entendu, par le léger serrage exercé par le sommet du filetage du manchon 5 contre l'extérieur de la jupe 10 du bec verseur, celui-ci reste disposé très près du fond 4 du bouchon, comme ex­pliqué plus haut. Une matrice vient se placer autour du bouchon et lui im­prime un mouvement de rotation, de telle sorte que son manchon 5 commence à se visser par rapport au filetage 11b du goulot 11.As usual, the assembly of the plug 1 and its pouring spout 2 is placed in an automatic dispenser intended to bring it opposite the neck 11 of a bottle 13. Of course, by the slight tightening exerted by the top of the thread of the sleeve 5 against the outside of the skirt 10 of the pouring spout, the latter remains disposed very close to the bottom 4 of the plug, as explained above. A matrix is placed around the plug and gives it a rotational movement, so that its sleeve 5 begins to screw with respect to the thread 11b of the neck 11.

A un moment donné, l'arête inférieure de la jupe 10 du verseur vient en contact avec la partie terminale du goulot 11, de telle sorte qu'un blocage angulaire du verseur s'effectue à cet instant. Dans ces conditions, les dents 4b du fond du bouchon 1 viennent en contact avec les crans 9a du bec verseur 2 en parcourant la distance qui les sépare à l'origine comme illus­tré en fig. 3 et 4. Dans ces conditions, la rotation du bouchon entraîne celle du verseur qui vient coopérer avec le bout non fileté du goulot 11 jusqu'à ce que la saillie 10b du verseur vienne s'engager dans la rainure 11d du goulot 11, comme illustré en fig. 5 et 6. Du fait que la retenue angulaire exercée sur le verseur 2 par l'assemblage saillie 10b rainure 11d est beaucoup plus importante que celle engendrée par l'appui des dents 4b sur les crans 9a, le verseur reste immobilisé angulairement tandis que les dents sautent par dessus les crans (fig. 7).At a given moment, the lower edge of the skirt 10 of the pourer comes into contact with the end portion of the neck 11, so that an angular blocking of the pourer takes place at this instant. Under these conditions, the teeth 4 b of the bottom of the plug 1 come into contact with the notches 9 a of the pouring spout 2 by covering the distance which originally separates them as illustrated in FIG. 3 and 4. Under these conditions, the rotation of the plug causes that of the pourer which comes to cooperate with the non-threaded end of the neck 11 until the projection 10 b of the pourer comes to engage in the groove 11 d of the neck 11 , as illustrated in fig. 5 and 6. Because the angular restraint exerted on the pourer 2 by the protruding assembly 10 b groove 11 d is much greater than that generated by the support of the teeth 4 b on the notches 9 a , the pourer remains immobilized angularly while the teeth jump over the notches (fig. 7).

Au fur et à mesure de l'enfoncement du bouchon par rapport au goulot, le verseur descend, le cordon 10a de la jupe 10 du bec verseur coopère avec l'extrémité du bout non fileté du goulot 11 (fig. 9), tandis que le ressaut 6a de la jupe extérieure 6 n'est pas bloqué par le redan 12a du col du fait que sa partie arrière est arrondie et qu'au contraire la partie avant dans le sens du vissage du redan est oblique. Il se passe une simple déformation de la jupe 6 lors du passage du ressaut sur le redan puisque le bouchon est réalisé en une matière plastique élastique.As the plug is pushed in with respect to the neck, the pourer descends, the cord 10 a of the skirt 10 of the pouring spout cooperates with the end of the non-threaded end of the neck 11 (fig. 9), while the projection 6 a of the outer skirt 6 is not blocked by the step 12 has a neck because its rear part is rounded and on the contrary the front part in the direction of screwing of the step is oblique. There is a simple deformation of the skirt 6 during the passage of the projection on the step since the plug is made of an elastic plastic material.

En fin de vissage, le cordon 10a de la face intérieure de la jupe 10 du bec verseur vient s'encliqueter dans la gorge 11c de l'extrémité non filetée du goulot 11, si bien qu'il est immobilisé axialement par ce moyen tandis qu'il est fixe angulairement par coopération de la saillie 10b dans la rai­nure 11d comme indiqué plus haut. Les choses sont arrangées de telle maniè­re qu'en fin de vissage, c'est-à-dire lorsque le fond du bouchon vient s'appuyer contre la couronne 9 du bec verseur qui est elle-même en appui contre l'extrémité du goulot 11, la face du ressaut 6a orientée normalement par rapport à la face interne de la jupe 6 se trouve en vis-à-vis immédiat de la face du redan 12a orientée normalement au col 12 (fig. 12). Ainsi le dévissage du bouchon est interdit.At the end of screwing, the cord 10 a of the inside face of the skirt 10 of the pouring spout snaps into the groove 11 c of the non-threaded end of the neck 11, so that it is immobilized axially by this means while it is fixed angularly by cooperation of the projection 10 b in the groove 11 d as indicated above. Things are arranged in such a way that at the end of screwing, that is to say when the bottom of the stopper comes to rest against the crown 9 of the pouring spout which is itself in abutment against the end of the neck 11, the face of the projection 6 a oriented normally with respect to the internal face of the skirt 6 is located immediately opposite the face of the step 12 a oriented normally at the neck 12 (fig. 12). Thus unscrewing the cap is prohibited.

Pour permettre ce dévissage, on prévoit avantageusement d'affecter au col 12 du flacon 3 une forme aplatie, c'est-à-dire qu'en fait son profil en plan est ovale avec les parties les plus rapprochées du centre situées dans un diamètre perpendiculaire au redan 6a (fig. 13) ; dans ces conditions, en appuyant de manière centripète sur la jupe 6 du bouchon 1 au niveau des deux aplatissements du col 12, on provoque la déformation de cette jupe, de telle sorte qu'alors le ressaut 6a se dégage vers l'extérieur par rapport au redan 12a comme illustré en fig. 13. Dans ces conditions, on peut dévis­er le bouchon et avoir accès au contenu du flacon 12. La partie active 7a du bec verseur 2 se trouve à l'opposé de la poignée 13 du flacon, si bien que le déversement du produit s'effectue correctement.To allow this unscrewing, provision is advantageously made to assign to the neck 12 of the bottle 3 a flattened shape, that is to say that in fact its profile in plan is oval with the parts closest to the center located in a diameter perpendicular to the step 6 a (fig. 13); under these conditions, by pressing in a centripetal manner on the skirt 6 of the plug 1 at the level of the two flattenings of the neck 12, this skirt is deformed, so that the projection 6 a is released towards the outside by compared to step 12 a as illustrated in fig. 13. Under these conditions, it is possible to unscrew the stopper and have access to the contents of the bottle 12. The active part 7 a of the pouring spout 2 is located opposite the handle 13 of the bottle, so that the spillage of the product s 'performs correctly.

Bien entendu, le rebouchage du flacon 13 s'effectue par simple vissage du bouchon. En fin de vissage, le ressaut 6a de la jupe extérieure vient co­opérer avec le redan pour déformer la jupe et permettre le vissage comme expliqué plus haut.Of course, the filling of the bottle 13 is carried out by simply screwing the cap. At the end of screwing, the projection 6a of the outer skirt cooperates with the recess to deform the skirt and allow the screw as explained above.

Bien entendu, les trois composants de la combinaison suivant l'invention peuvent être fabriqués en toute matière appropriée, mais on choisit avanta­ geusement de mouler le bouchon et le verseur en une matière plastique semi-­rigide du genre du polypropylène, tandis que le flacon est moulé par souf­flage en une matière telle que le PCV rigide ou analogue.Of course, the three components of the combination according to the invention can be made of any suitable material, but we choose avanta It is a good idea to mold the stopper and the pourer into a semi-rigid plastic material such as polypropylene, while the bottle is blow molded from a material such as rigid PCV or the like.

Bien entendu, on peut prévoir deux redans diamétralement opposés destinés à coopérer avec deux ressauts orientés de manière correspondante sur la jupe extérieure ou encore prévoir une multiplicité de dents 4b et de crans 9a, le tout étant déterminé de manière que lors du vissage initial de l'ensem­ble bouchon-bec verseur sur le goulot du récipient, le bec verseur reste orienté de manière définitive par coopération de sa saillie 10b dans la rainure 11d du goulot.Of course, it is possible to provide two diametrically opposite steps intended to cooperate with two projections oriented in a corresponding manner on the outer skirt or else to provide a multiplicity of teeth 4 b and notches 9 a , the whole being determined so that during the initial screwing of the stopper-spout assembly on the neck of the container, the spout remains permanently oriented by cooperation of its projection 10b in the groove 11d of the neck.

On observera que pour des raisons de facilité de montage, le redan 12a est disposé perpenculairement au diamètre passant par la ranure 11d.It will be observed that for reasons of ease of assembly, the step 12 a is arranged perpetually with the diameter passing through the groove 11 d .

En particulier, la saillie 10b pourait être une dépression et la rainure 11b une saillie. De même la dent 4d pourrait être placée à n'importe quelle zone de l'intérieur du bouchon 1 le cran 9a étant placé en correspondance sur le verseur 2.In particular, the projection 10 b could be a depression and the groove 11 b a projection. Similarly, the tooth 4 d could be placed at any zone inside the stopper 1 the notch 9 a being placed in correspondence on the pourer 2.
