Description

DOMAINE TECHNIQUE GENERALGENERAL TECHNICAL FIELD

La présente invention concerne le domaine des tubes souples comprenant un opercule obturant le goulot préalablement à la première utilisation du tube, et un bouchon perforateur adapté pour réaliser le perçage de l'opercule.The present invention relates to the field of flexible tubes comprising a cap sealing the neck prior to the first use of the tube, and a perforating plug adapted to perform the piercing of the cap.

ETAT DE L'ARTSTATE OF THE ART

On connait les tubes munis d'un opercule associés à un bouchon perforateur comprenant un poinçon adapté pour perforer ledit opercule lorsque le bouchon est inséré dans un premier sens dans le goulot du tube, et pour être vissé sur le goulot lorsqu'il est positionné dans un deuxième sens sur le goulot du tube.Tubes provided with a cap associated with a perforating plug are known comprising a punch adapted to perforate said cap when the cap is inserted in a first direction in the neck of the tube, and to be screwed onto the neck when positioned in a second sense on the neck of the tube.

L'opercule permet en effet de conserver le produit contenu dans le tube de manière hermétique pendant son stockage préalablement à sa première utilisation, ce qui représente une part très importante de la durée de vie globale du tube.The seal makes it possible to keep the product contained in the tube hermetically during storage before its first use, which represents a very important part of the overall service life of the tube.

De telles solutions sont toutefois peu pratiques et assez peu appréciées des utilisateurs. Elles conduisent en outre à avoir un tube ayant un poinçon faisant saillie de son bouchon lors de son utilisation et de son stockage, et nécessitent un effort de poussée pour percer l'opercule à l'aide du poinçon du bouchon.Such solutions are, however, impractical and not very popular with users. They also lead to having a tube having a punch protruding from its cap during its use and storage, and require a thrust force to pierce the cap using the plug punch.

Afin de corriger ces inconvénients, des solutions ont été proposées dans lesquelles le poinçon est disposé dans le bouchon, de manière à pouvoir perforer l'opercule lorsque le bouchon est vissé sur la tête de tube. Toutefois, afin d'assurer la préservation de l'opercule préalablement à la première utilisation, une bague d'espacement est disposée entre le bouchon et l'épaule de la tête de tube, de manière à maintenir le poinçon à distance de l'opercule lorsque le bouchon est vissé sur le goulot.In order to correct these drawbacks, solutions have been proposed in which the punch is placed in the stopper so as to be able to perforate the cover when the stopper is screwed onto the tube head. However, in order to ensure the preservation of the cap prior to the first use, a spacer ring is disposed between the cap and the shoulder of the tube head, so as to maintain the punch at a distance from the lid when the cap is screwed onto the neck.

De telles solutions sont toutefois très contraignantes industriellement en ce qu'elles nécessitent le positionnement de plusieurs pièces sur la tête de tube, la bague et le bouchon étant communément formés de deux pièces distinctes.Such solutions, however, are very demanding industrially in that they require the positioning of several parts on the tube head, the ring and the plug being commonly formed of two separate parts.

Il a également été proposé ( CH 576 376 , DE 20 2004 004 539 U1 ) de réaliser le bouchon et la bague en une seule pièce venue de matière, ces deux éléments étant ainsi reliés par des ponts de matière adaptés pour être rompus par vissage ou dévissage du bouchon. Cependant, le positionnement par machine du bouchon sur la tête de tube requiert alors une précision extrême afin de ne pas rompre systématiquement les ponts de matière lors du bouchonnage, rendant cette solution non exploitable.It has also been proposed ( CH 576 376 , DE 20 2004 004 539 U1 ) to achieve the cap and the ring in one piece made of material, these two elements being thus connected by material bridges adapted to be broken by screwing or unscrewing the plug. However, the machine positioning of the cap on the tube head then requires extreme precision so as not to systematically break the bridges of material during capping, making this solution unworkable.

PRESENTATION DE L'INVENTIONPRESENTATION OF THE INVENTION

La présente invention vise à proposer un ensemble comprenant une tête de tube comprenant un opercule et un bouchon muni d'un poinçon adapté pour assurer la préservation de l'opercule préalablement à la première utilisation, tout en étant exploitable à l'échelle industrielle pour les opérations de fabrication et de positionnement du bouchon sur la tête de tube.The present invention aims to provide an assembly comprising a tube head comprising a cap and a plug provided with a punch adapted to ensure the preservation of the cap prior to the first use, while being exploitable on an industrial scale for the manufacturing operations and positioning of the cap on the tube head.

caractérisé en ce que la bague comprend des butées internes adaptées pour limiter le déplacement dudit bouchon au travers de la bague, de manière à maintenir le poinçon à distance de l'opercule lorsque le bouchon est vissé sur le goulot et en butée contre la bague.For this purpose, the invention proposes an assembly comprising
  • a tube head comprising a neck defining a longitudinal axis, a shoulder and a solid insert forming a lid closing said neck,
  • a stopper comprising a punch adapted to cut the lid, said cap being adapted to be screwed onto said neck, and configured so that when said stopper is screwed onto the neck, the punch is inserted inside the neck,
  • a removable spacer ring disposed on the shoulder around the neck,

characterized in that the ring comprises internal stops adapted to limit the displacement of said plug through the ring, so as to keep the punch away from the cap when the cap is screwed onto the neck and abutting against the ring.

Ledit ensemble présente typiquement une ou plusieurs des caractéristiques optionnelles suivantes, prises indépendamment ou en combinaison ;

  • ledit poinçon est adapté pour après le retrait de la bague d'espacement de l'ensemble, lorsque ledit bouchon est vissé en butée contre l'épaule, réaliser une découpe partielle dudit opercule afin d'ouvrir ledit goulot, l'opercule étant alors lié à la partie non découpée de l'insert par un pont de matière.

Said assembly typically has one or more of the following optional features, taken independently or in combination;
  • said punch is adapted for after removal of the spacer ring from the assembly, when said plug is screwed abutting against the shoulder, making a partial cutout of said lid to open said neck, the lid being then bound to the uncut portion of the insert by a material bridge.

La bague 3 d'espacement est configurée de manière à pouvoir être disposée autour du goulot 11, en appui contre l'épaule 12, et ainsi maintenir un espacement entre le bouchon 2 et l'épaule 12 lorsque le bouchon 2 est vissé sur le goulot 11 et que les ponts de matière 31 liant la bague 3 d'espacement et le bouchon 2 n'ont pas été rompus.The spacer ring 3 is configured so as to be arranged around the neck 11, resting against the shoulder 12, and thus maintain a spacing between the cap 2 and the shoulder 12 when the cap 2 is screwed onto the neck 11 and that the bridges of material 31 connecting the spacer ring 3 and the plug 2 have not been broken.

Plus précisément, la bague 3 d'espacement est configurée de manière à maintenir le poinçon 22 à distance de l'insert 13 lorsque le bouchon 2 est vissé sur le goulot 11 et que les ponts de matière 31 liant la bague 3 d'espacement et le bouchon 2 n'ont pas été rompus, empêchant ainsi le poinçon de venir au contact de l'insert 13 et l'empêchant donc de percer ou de découper l'opercule formé dans le goulot 11.More specifically, the spacer ring 3 is configured to keep the punch 22 away from the insert 13 when the cap 2 is screwed onto the neck 11 and the material bridges 31 connecting the ring 3 spacing and the cap 2 have not been broken, thus preventing the punch from coming into contact with the insert 13 and thus preventing it from piercing or cutting the lid formed in the neck 11.

La figure 1 présente cette configuration, dans laquelle la bague 3 d'espacement est liée au bouchon 2 par les ponts de matière 31, et est disposée autour du goulot 11, en appui contre l'épaule 12 alors que le bouchon 2 est vissé sur le goulot 11. Le poinçon 22 s'étend alors à l'intérieur du goulot 11, à une distance non nulle de l'insert 13, préservant ainsi l'opercule de toute découpe ou perforation.The figure 1 this configuration, in which the spacer ring 3 is connected to the plug 2 by the material bridges 31, and is arranged around the neck 11, bearing against the shoulder 12 while the cap 2 is screwed onto the neck 11 The punch 22 then extends inside the neck 11, at a non-zero distance from the insert 13, thus preserving the lid from any cutting or perforation.

De cette manière, l'ensemble formé du bouchon 2 et de la bague 3 d'espacement peut être vissé sur le goulot 11, jusqu'à ce que la bague 3 d'espacement vienne en butée contre l'épaule 12, l'insert 13 étant préservé de tout poinçonnage ou découpe comme détaillé précédemment.In this way, the assembly formed of the plug 2 and the spacer ring 3 can be screwed onto the neck 11, until the spacer ring 3 abuts against the shoulder 12, the insert 13 being preserved from punching or cutting as detailed previously.

De plus, la bague 3 et le bouchon 2 sont réalisés de sorte que la bague 3 présente un diamètre interne DI supérieur au diamètre externe DE du bouchon 2, de manière à permettre un coulissement du bouchon 2 au travers de la bague 3 après rupture desdits ponts de matière 31.In addition, the ring 3 and the plug 2 are made so that the ring 3 has an internal diameter DI greater than the outer diameter DE of the plug 2, so as to allow the plug 2 to slide through the ring 3 after rupture of said material bridges 31.

A l'échelle industrielle, le bouchonnage, c'est-à-dire l'étape lors de laquelle le bouchon 2 est vissé sur le goulot 11 est typiquement réalisée au moyen d'une bouchonneuse. Toutefois, il est très délicat de configurer une telle machine afin qu'elle visse le bouchon 2 sur le goulot 11 jusqu'au point précis où la bague 3 d'espacement est en butée contre l'épaule 11 tout en préservant les ponts de matière 31. En effet, si la rotation du bouchon 2 pour le visser sur le goulot 11 est légèrement trop importante, les ponts de matière 31 se rompent, et le bouchon 2 est désolidarisé de la bague 3 d'espacement, ce qui peut provoquer la perforation de l'insert 13.On an industrial scale, corking, that is to say the step in which the cap 2 is screwed onto the neck 11 is typically performed by means of a corker. However, it is very difficult to configure such a machine so that it screws the cap 2 on the neck 11 to the precise point where the spacer ring 3 abuts against the shoulder 11 while preserving the bridges of material 31. Indeed, if the rotation of the plug 2 to screw on the neck 11 is slightly too large, the material bridges 31 break, and the plug 2 is separated from the spacer ring 3, which can cause the perforation of the insert 13.

Afin que la bague 3 d'espacement assure la protection de l'opercule même après rupture des ponts de matière 31 la liant au bouchon 2 et sans calibration extrêmement précise de la bouchonneuse, la bague 3 d'espacement comprend des butées internes 33 adaptées pour limiter le déplacement du bouchon 2 au travers de la bague 3 d'espacement une fois les ponts de matière 31 rompus, de manière à maintenir le poinçon 22 à distance de l'opercule lorsque le bouchon 2 est vissé sur le goulot 11 et en butée contre lesdites butées internes 33 de la bague 3.So that the spacer ring 3 ensures the protection of the seal even after rupture of the material bridges 31 the binder to the cap 2 and without extremely accurate calibration of the corker, the spacer ring 3 comprises internal stops 33 adapted to limit the displacement of the plug 2 through the spacer ring 3 once the bridges material 31 broken, so as to keep the punch 22 away from the cap when the cap 2 is screwed on the neck 11 and abut against said internal stops 33 of the ring 3.

Les figures 5 et 6 présentent l'action de ces butées internes 33 lors de la rupture des ponts de matière 31 pour limiter le déplacement du bouchon 2 au travers de la bague 3 d'espacement.The figures 5 and 6 show the action of these internal stops 33 during the rupture of the material bridges 31 to limit the displacement of the plug 2 through the spacer ring 3.

Les butées internes 33 sont ainsi typiquement dimensionnées de manière à définir un diamètre interne réduit DR de la bague 3 d'espacement, inférieur au diamètre externe du bouchon 2.The internal stops 33 are thus typically dimensioned so as to define a reduced internal diameter DR of the spacer ring 3, smaller than the external diameter of the plug 2.

La figure 5 présente le bouchon 2 et la bague 3 d'espacement reliés par les ponts de matière 31 préalablement à leur rupture. Les butées internes 33 sont ici formées par des nervures internes longitudinales.The figure 5 presents the plug 2 and the spacer ring 3 connected by the material bridges 31 before they break. The internal stops 33 are here formed by longitudinal internal ribs.

La figure 6 présente quant à elle le bouchon 2 et la bague 3 d'espacement suite à la rupture des ponts de matière 31. Le bouchon 2 a coulissé dans la bague 3 d'espacement, jusqu'aux butées internes 33 qui limitent ce coulissement, de sorte que le poinçon 22 soit maintenu à distance de l'opercule lorsque le bouchon 2 est vissé sur le goulot 11 et en appui contre les butées internes 33 de la bague 3 d'espacement, la bague 3 d'espacement étant en appui contre l'épaule 12 de la tête de tube 1.The figure 6 as for the plug 2 and the spacer ring 3 following rupture of the material bridges 31. The plug 2 has slid into the spacer ring 3, as far as the internal stops 33 which limit this sliding, so that that the punch 22 is kept at a distance from the lid when the cap 2 is screwed onto the neck 11 and bears against the internal stops 33 of the spacer ring 3, the spacer ring 3 being in abutment against the shoulder 12 of the tube head 1.

Cette limitation du coulissement du bouchon 2 dans la bague 3 d'espacement assure que le poinçon est maintenu à distance de l'opercule, et ce dernier est ainsi préservé de toute découpe ou perforation, même en cas de rupture des ponts de matière 31, que cette rupture soit volontaire ou non.This limitation of the sliding of the stopper 2 in the spacer ring 3 ensures that the punch is kept at a distance from the lid, and the latter is thus preserved from any cutting or perforation, even in case of rupture of the material bridges 31, whether this break is voluntary or not.

On peut ainsi calibrer une bouchonneuse de manière à réaliser la rupture des ponts de matière 31 lors du bouchonnage, de sorte que l'utilisateur puisse se contenter de dévisser le bouchon 2, retirer la bague 3, puis visser le bouchon 2 sur le goulot de manière à perforer ou découper l'opercule, et ainsi permettre une distribution du produit contenu dans le tube.It is thus possible to calibrate a corker so as to break the material bridges 31 during corking, so that the user can simply unscrew the plug 2, remove the ring 3, then screw the plug 2 onto the neck of the cork. way to punch or cut out the lid, and thus allow a distribution of the product contained in the tube.

Les butées internes 33 définissent ainsi une course limitée du bouchon 2 du travers de la bague 3 d'espacement après la rupture des ponts de matière 31, typiquement égale à 1mm. Une telle course limitée permet l'utilisation d'une bouchonneuse industrielle afin de visser l'ensemble composé du bouchon 2 et de la bague 3 d'espacement sur le goulot 11, tout en préservant l'opercule de toute perforation ou découpe en cas de rupture des ponts de matière résultant du calibrage de la bouchonneuse.The internal stops 33 thus define a limited stroke of the stopper 2 through the spacer ring 3 after breaking the bridges of material 31, typically equal to 1 mm. Such a limited stroke allows the use of an industrial corker to screw the assembly consisting of the plug 2 and the spacer ring 3 on the neck 11, while preserving the seal of any perforation or cutting in case of rupture of the bridges of material resulting from the calibration of the corker.

Lors de la première utilisation, l'utilisateur dévisse le bouchon 2 du goulot 11, puis retire la bague 3 d'espacement préalablement désolidarisée du bouchon 2 par la rupture des ponts de matière 31, et revisse le bouchon 2 sur le goulot 11 jusqu'à ce qu'il vienne en butée contre le goulot 11 ou contre l'épaule 12. Le poinçon 22 a alors réalisé une découpe ou une perforation de l'insert 13, et plus précisément de sa partie centrale 17 formant l'opercule de la tête de tube.During the first use, the user unscrews the cap 2 of the neck 11, then removes the spacer ring 3 previously disconnected from the plug 2 by breaking the material bridges 31, and screw the cap 2 on the neck 11 until it comes into abutment against the neck 11 or against the shoulder 12. The punch 22 then made a cut or a perforation of the insert 13, and more precisely of its central portion 17 forming the lid of the tube head.

La découpe de l'opercule est avantageusement partielle, de manière à ce que la ou les portions de l'opercule ayant été découpées demeurent liées au reste de l'insert 13, prévenant ainsi tout mélange du matériau formant l'insert 13 avec un produit contenu dans le tube associé, et une éventuelle distribution de ce matériau à l'utilisateur.The cutting of the lid is advantageously partial, so that the portion or portions of the lid having been cut remain connected to the rest of the insert 13, thus preventing any mixing of the material forming the insert 13 with a product. contained in the associated tube, and a possible distribution of this material to the user.

A titre d'exemple, en considérant qu'une découpe complète est une découpe à 360° de l'opercule, c'est-à-dire une découpe circulaire réalisée par rotation du bouchon 2, on réalise avantageusement une découpe comprise entre 250° et 330°, formant ainsi un lien suffisant pour assurer la cohésion entre la section centrale 17 ayant été découpée, et la section périphérique 16.By way of example, considering that a complete cut is a 360 ° cutout of the cap, that is to say a circular cut made by rotation of the stopper 2, a cutting of between 250.degree. and 330 °, thus forming a link sufficient to ensure cohesion between the central section 17 having been cut, and the peripheral section 16.

Les figures 1, 5 et 6 présentent plusieurs exemples de forme du poinçon 22.The figures 1 , 5 and 6 present several examples of shape of the punch 22.

Dans le mode de réalisation représenté sur la figure 1, le poinçon 22 a une section cylindrique de révolution, dont une extrémité libre 23 est biseautée, de manière à ce que lorsque le bouchon 2 est vissé sur le goulot 11 de la tête de tube 1, l'extrémité libre 23 du poinçon 22 soit insérée dans le goulot 11, et qu'elle soit biseautée par rapport à un plan normal à l'axe Z-Z du goulot 11, l'opercule formé par l'insert 13 étant typiquement disposé dans un tel plan normal à l'axe Z-Z du goulot 11. L'extrémité libre 23 du poinçon 22 a par conséquent une section de cercle s'inscrivant dans un plan incliné par rapport à l'axe Z-Z du goulot 11, qui coïncide avec l'axe longitudinal du bouchon 2.In the embodiment shown on the figure 1 , the punch 22 has a cylindrical section of revolution, a free end 23 of which is bevelled, so that when the cap 2 is screwed onto the neck 11 of the tube head 1, the free end 23 of the punch 22 is inserted in the neck 11, and that it be beveled with respect to a plane normal to the axis ZZ of the neck 11, the lid formed by the insert 13 being typically arranged in such a plane normal to the axis ZZ of the neck 11. The free end 23 of the punch 22 therefore has a section of a circle in a plane inclined with respect to the axis ZZ of the neck 11, which coincides with the longitudinal axis of the stopper 2.

Dans le mode de réalisation représenté, un chanfrein est de plus réalisé à la bordure interne de l'extrémité libre 23 du poinçon 22, permettant ainsi d'en réduire l'épaisseur pour rentre l'extrémité libre 23 coupante, ce qui facilite la découpe de l'opercule par le poinçon 22.In the embodiment shown, a chamfer is furthermore made at the inner edge of the free end 23 of the punch 22, thus making it possible to reduce the thickness thereof to fit the free cutting end 23, which facilitates cutting. of the operculum by the punch 22.

Un autre mode de réalisation du poinçon 22 du bouchon 2 est illustré sur les figures 5 et 6, la forme de l'extrémité libre 23 du poinçon 22 est similaire à celle présentée sur la figure 1, mais s'étend uniquement sur un demi-cercle biseauté comme décrit précédemment, l'autre partie de l'extrémité libre 23 étant évidée de manière à être en retrait dudit demi-cercle biseauté. Une telle forme favorise la découpe de l'opercule par le poinçon, alors que le mode de réalisation précédent réalise une découpe du poinçon par écrasement.Another embodiment of the punch 22 of the plug 2 is illustrated on the figures 5 and 6 , the shape of the free end 23 of the punch 22 is similar to that presented on the figure 1 but only extends over a beveled half-circle as described above, the other part of the free end 23 being recessed so as to be set back from said beveled half-circle. Such a shape promotes the cutting of the seal by the punch, while the previous embodiment performs a cutting of the punch by crushing.

Dans le mode de réalisation représenté, l'épaule 12 de la tête de tube 1 comprend des reliefs 15 optionnels formant saillie, radialement à partir de la jonction entre le goulot 11 et l'épaule 12. Ces reliefs 15 optionnels sont alors typiquement dimensionnés de manière à présenter un diamètre inférieur ou égal au diamètre interne de la bague 3. La bague 3 d'espacement est alors munie de moyens tels que des nervures 32 internes, adaptés pour coopérer avec lesdits reliefs afin de ne permettre sa rotation autour du goulot 12 selon l'axe Z-Z que dans un sens unique correspondant au sens de vissage du bouchon 2 sur le goulot 11, les reliefs 15 coopérant avec les nervures 32 afin d'empêcher la rotation de la bague 3 d'espacement autour du goulot 12 dans le sens du dévissage du bouchon 2 du goulot 11 de la tête de tube 1.In the embodiment shown, the shoulder 12 of the tube head 1 comprises optional reliefs projecting radially from the junction between the neck 11 and the shoulder 12. These optional reliefs are then typically dimensioned by so as to have a diameter less than or equal to the inner diameter of the ring 3. The spacer ring 3 is then provided with means such as internal ribs 32, adapted to cooperate with said reliefs to allow its rotation around the neck 12 along the ZZ axis, that in a single direction corresponding to the screwing direction of the plug 2 on the neck 11, the reliefs 15 cooperating with the ribs 32 to prevent the rotation of the spacer ring 3 around the neck 12 in the direction of unscrewing the cap 2 of the neck 11 of the tube head 1.

La figure 4 présente un exemple de mode de réalisation comprenant des reliefs 15 optionnels, ayant une forme générale d'hélice autour de l'axe Z-Z. Plusieurs modes de réalisation sont possibles ; les reliefs 15 optionnels peuvent par exemple former des arcs de cercles s'étendant à partir du centre du goulot 11 afin de former une forme générale de spirale, ou encore une forme générale de roue dentée.The figure 4 shows an exemplary embodiment including optional reliefs, having a generally helical shape around the ZZ axis. Several embodiments are possible; the optional reliefs may for example form arcs of circles extending from the center of the neck 11 to form a general spiral shape, or a general toothed form.

Selon un mode de réalisation particulier, les nervures 32 internes réalisant également la fonction d'arrêt en rotation en coopérant avec les reliefs 15 de l'épaule 12 peuvent également former les butées internes 33 limitant le coulissement du bouchon 2 au travers de la bague 3 d'espacement.According to a particular embodiment, the internal ribs 32 also performing the rotational stop function cooperating with the reliefs 15 of the shoulder 12 can also form the internal stops 33 limiting the sliding of the plug 2 through the ring 3 spacing.

L'ensemble décrit permet ainsi d'obtenir une tête de tube munie d'un opercule assurant la conservation hermétique d'un produit préalablement à sa première utilisation et associée à un bouchon perforateur amélioré assurant une découpe contrôlée par l'utilisateur lors d'un simple vissage du bouchon, tout en empêchant toute découpe ou perçage prématuré de l'opercule et en permettant un bouchonnage industriel.The assembly described thus makes it possible to obtain a tube head provided with a lid ensuring the hermetic preservation of a product prior to its first use and associated with an improved perforating plug ensuring a cut-off controlled by the user during a simple screwing of the cap, while preventing any cutting or premature piercing of the cap and allowing industrial capping.

En outre, la découpe partielle de l'opercule permet d'éviter sa chute dans le volume interne du tube ou son expulsion par le goulot de la tête de tube, et donc plus généralement son mélange avec le produit et sa distribution à l'utilisateur.In addition, the partial cut of the lid prevents its fall into the internal volume of the tube or its expulsion through the neck of the tube head, and therefore more generally its mixing with the product and its distribution to the user .
