- Tubes provided with a cap associated with a perforating cap 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 it is positioned in the tube are known. a second sense on the neck of the 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.
- 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.
- said shoulder comprises protruding reliefs adapted to cooperate with non-return means arranged on an inner wall of the spacer ring in order to lock in rotation the ring around the neck in the unscrewing direction of the cap of the neck, so that the unscrewing of the cap relative to the neck causes a rupture of the material bridges to separate the spacer ring of the plug.
- said punch is adapted for after removal of the spacer ring from the assembly, when said plug is screwed in abutment against the shoulder, making a partial cutout of said lid to open said neck , the seal being then connected to the uncut portion of the insert by a material bridge.
- said spacer ring comprises a plurality of ribs adapted to center the spacer ring around the neck.
- said spacer ring has a shape of a circle portion of which a free end forms a tongue prehensible by a user.
- said punch has a free end beveled in a plane inclined relative to the longitudinal axis of the neck when the cap is screwed onto said neck. Said free beveled end then typically has a semicircular cross section.
- the invention thus ensures a maintenance of material bridges between the ring and the cap during their screwing on the tube head by an industrial corker, which ensures their relative positioning and thus allows the ring to play a stopper role so to preserve the operculum of any perforation or cutting prior to the first use of the assembly by a user.
- this maintenance material bridges between the ring and the cap performs a function of opening control; the presence of material bridges between the ring and the plug during the first use ensures that the plug has never been removed before.
- the tube head 1 comprises a neck 11 defining a longitudinal axis ZZ, a shoulder 12 and a solid insert 13 forming a lid closing said neck 11. More specifically, the insert 13 comprises a peripheral section 16, typically of frustoconical or disc shape, and a central section 17 forming said lid, whose diameter typically corresponds to the internal diameter of the neck 11.
- the neck 11 comprises a thread 14 on its outer periphery, adapted to allow the cap 2 to be screwed onto the neck 11.
- the plug 2 comprises an internal thread 21 adapted to cooperate with the thread 14 of the neck 11, and a punch 22 configured to be inserted into the neck 11 of the tube head 1 when the plug 2 is screwed onto said neck 11.
- the spacer ring 3 and the plug 2 are integrally formed in one piece, and are thus connected by material bridges 31 shown on the drawing. figure 2 .
- 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.
- 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.
- 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 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.
- the ring 3 and the plug 2 are made so that the ring 3 has an internal diameter greater than the external diameter of the plug 2, so as to allow the plug 2 to slide through the ring 3 after rupture of said material bridges 31.
- 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.
- 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.
- the punch 22 of the plug 2 has a free end 23 similar to that presented on the figure 1 but extending only 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.
- a shape promotes the cutting of the seal by the punch, while the previous embodiment performs a cutting of the punch by crushing.
- the shoulder 12 of the tube head 1 comprises reliefs 15 projecting radially from the junction between the neck 11 and the shoulder 12.
- the spacer ring 3 is provided with means such as internal ribs 32 adapted to cooperate with said reliefs 15 so as to allow its rotation around the neck 12 along the axis ZZ only in a single direction corresponding to the screwing direction of the cap 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.
- the figure 3 shows an exemplary embodiment comprising reliefs 15 having a generally helical shape around the ZZ axis.
- the reliefs 15 may for example form arcs of circles extending from the center of the neck 11 to form a general spiral shape, or a general form of toothed wheel.
- the user unscrews the cap 2 of the neck 11.
- the reliefs 15 and inner ribs 32 then cooperate to block the ring 3 rotating spacing.
- the spacer ring 3 thus remains stationary while the stopper 2 is unscrewed, which causes rupture of the material bridges 31 and the separation of the ring 3 with respect to the stopper 2.
- the user removes the spacer ring 3 by sliding it along the neck 11, then screws the cap 2 again on the neck 11, until the plug 2 is in abutment against the neck 11 or against the shoulder 12, which causes a cut or perforation of the lid formed by the central section 17 of the insert 13 by the punch 22 of the plug 2 whose free end 23 passes through the central section 17 of the insert 13.
- 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 complete cutout is a 360 ° cutout of the cap, that is to say a circular cut made by rotation of the cap 2
- 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.
- corking 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 cap 2 to screw on the neck 11 is slightly too large, the material bridges 31 are broken, and the cap 2 is disengaged from the spacer ring 3.
- the spacer ring 3 and the stopper 2 comprise lugs 34 and housings 35 cooperating in such a way as to limit their relative rotation with respect to each other. the other in the direction of screwing the cap 2 on the neck 11 to prevent the rupture of said bridges of material between the ring 3 and the cap 2 during screwing of the cap 2 on the neck 11.

- the lugs 34 typically extend in a plane perpendicular to the axis ZZ of the neck 11.
- the pins 34 and housing 35 being disjoint, a small relative rotation between the plug 2 and the spacer ring 3 is possible due to a spacing 36 between the lugs 34 and the housing 35.
- the spacing 36 between the lugs 34 and the housings 35 is dimensioned according to the mechanical properties of the material of which the plug 2 and the spacer ring 3 are formed, and in particular its elastic and plastic deformation properties, so that the relative rotation that it allows between the plug 2 and the ring 3 causes a deformation of the material bridges 31 less than its resistance to rupture.

Abstract
Description
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.
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 cap 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 it is positioned in the tube are known. 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.
De telles solutions sont toutefois très contraignantes industriellement en ce qu'elles nécessitent le positionnement de plusieurs pièces sur la tête de tube.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.
Such solutions, however, are very demanding industrially in that they require the positioning of several parts on the tube head.
Il a également été proposé 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 to make 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.
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.
A cet effet, l'invention propose un ensemble comprenant
- une tête de tube comprenant un goulot définissant un axe longitudinal, une épaule et un insert plein formant un opercule obturant ledit goulot,
- un bouchon comprenant un poinçon adapté pour découper l'opercule, ledit bouchon étant adapté pour être vissé sur ledit goulot, et configuré de manière à ce que lorsque ledit bouchon est vissé sur le goulot, le poinçon soit inséré dans le goulot,
- une bague d'espacement amovible disposée en appui sur l'épaule autour du goulot,
caractérisé en ce que la bague et le bouchon comprennent des ergots et logements coopérant de manière à limiter leur rotation relative de l'un par rapport à l'autre dans le sens du vissage du bouchon sur le goulot afin d'empêcher la rupture desdits ponts de matière entre la bague et le bouchon lors du vissage du bouchon sur le goulot.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 cap is screwed onto the neck, the punch is inserted into the neck,
- a removable spacer ring disposed on the shoulder around the neck,
characterized in that the ring and the cap comprise lugs and housings cooperating so as to limit their relative rotation relative to each other in the direction of screwing the cap on the neck to prevent the breaking of said bridges. of material between the ring and the cap during screwing of the cap on the neck.
Selon un mode de réalisation particulier, ladite épaule comprend des reliefs faisant saillie adaptés pour coopérer avec des moyens anti-retour aménagés sur une paroi interne de la bague d'espacement afin de bloquer en rotation la bague autour du goulot dans le sens du dévissage du bouchon du goulot, de sorte que le dévissage du bouchon par rapport au goulot entraine une rupture des ponts de matière pour désolidariser la bague d'espacement du bouchon.According to a particular embodiment, said shoulder comprises protruding reliefs adapted to cooperate with non-return means arranged on an inner wall of the spacer ring in order to lock in rotation the ring around the neck in the unscrewing direction of the cap of the neck, so that the unscrewing of the cap relative to the neck causes a rupture of the material bridges to separate the spacer ring of the plug.
Selon un mode de réalisation particulier, 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.According to a particular embodiment, said punch is adapted for after removal of the spacer ring from the assembly, when said plug is screwed in abutment against the shoulder, making a partial cutout of said lid to open said neck , the seal being then connected to the uncut portion of the insert by a material bridge.
Selon un mode de réalisation particulier, ladite bague d'espacement comprend une pluralité de nervures adaptées pour centrer la bague d'espacement autour du goulot.According to a particular embodiment, said spacer ring comprises a plurality of ribs adapted to center the spacer ring around the neck.
Selon un mode de réalisation particulier, ladite bague d'espacement présente une forme de portion de cercle dont une extrémité libre forme une languette préhensible par un utilisateur.According to a particular embodiment, said spacer ring has a shape of a circle portion of which a free end forms a tongue prehensible by a user.
Selon un mode de réalisation particulier, ledit poinçon présente une extrémité libre biseautée selon un plan incliné par rapport à l'axe longitudinal du goulot lorsque le bouchon est vissé sur ledit goulot. Ladite extrémité libre biseautée présente alors typiquement une section transversale en demi-cercle.According to a particular embodiment, said punch has a free end beveled in a plane inclined relative to the longitudinal axis of the neck when the cap is screwed onto said neck. Said free beveled end then typically has a semicircular cross section.
L'invention assure ainsi un maintien des ponts de matière entre la bague et le bouchon lors de leur vissage sur la tête de tube par une bouchonneuse industrielle, ce qui assure leur positionnement relatif et donc permet à la bague de jouer un rôle de butée afin de préserver l'opercule de toute perforation ou découpe préalablement à la première utilisation de l'ensemble par un utilisateur.The invention thus ensures a maintenance of material bridges between the ring and the cap during their screwing on the tube head by an industrial corker, which ensures their relative positioning and thus allows the ring to play a stopper role so to preserve the operculum of any perforation or cutting prior to the first use of the assembly by a user.
En outre, ce maintien des ponts de matière entre la bague et le bouchon réalise une fonction de témoin d'ouverture ; la présence des ponts de matière entre la bague et le bouchon lors de la première utilisation assure que le bouchon n'a jamais été retiré antérieurement.In addition, this maintenance material bridges between the ring and the cap performs a function of opening control; the presence of material bridges between the ring and the plug during the first use ensures that the plug has never been removed before.

Selon un autre mode de réalisation, le poinçon 22 du bouchon 2 a une extrémité libre 23 similaire à celle présentée sur la
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.According to another embodiment, the
Such a shape promotes the cutting of the seal by the punch, while the previous embodiment performs a cutting of the punch by crushing.
L'épaule 12 de la tête de tube 1 comprend des reliefs 15 formant saillie, radialement à partir de la jonction entre le goulot 11 et l'épaule 12.
La bague 3 d'espacement est munie de moyens tels que des nervures 32 internes, adaptés pour coopérer avec lesdits reliefs 15 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.The
The
La
Plusieurs modes de réalisation sont possibles ; les reliefs 15 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
Several embodiments are possible; the
Lors de la première utilisation, l'utilisateur dévisse le bouchon 2 du goulot 11. Les reliefs 15 et nervures internes 32 coopèrent alors afin de bloquer la bague 3 d'espacement en rotation.
La bague 3 d'espacement reste donc immobile tandis que le bouchon 2 est dévissé, ce qui provoque une rupture des ponts de matière 31 et la désolidarisation de la bague 3 par rapport au bouchon 2.
Une fois le bouchon 2 dévissé et retiré du goulot 11, l'utilisateur retire la bague 3 d'espacement en la faisant glisser le long du goulot 11, puis visse à nouveau le bouchon 2 sur le goulot 11, jusqu'à ce que le bouchon 2 soit en butée contre le goulot 11 ou contre l'épaule 12, ce qui entraine une découpe ou perforation de l'opercule formé par la section centrale 17 de l'insert 13 par le poinçon 22 du bouchon 2 dont l'extrémité libre 23 traverse la section centrale 17 de l'insert 13.During the first use, the user unscrews the

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.
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.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
For example, considering that a complete cutout is a 360 ° cutout of the cap, that is to say a circular cut made by rotation of the
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.
Afin d'éviter un tel risque de rupture des ponts de matière 31 lors du bouchonnage, la bague 3 d'espacement et le bouchon 2 comprennent des ergots 34 et logements 35 coopérant de manière à limiter leur rotation relative de l'un par rapport à l'autre dans le sens du vissage du bouchon 2 sur le goulot 11 afin d'empêcher la rupture desdits ponts de matière entre la bague 3 et le bouchon 2 lors du vissage du bouchon 2 sur le goulot 11.On an industrial scale, corking, that is to say the step in which the
In order to avoid such a risk of rupture of the material bridges 31 during capping, the
La
Les ergots 34 et logements 35 sont aménagés de manière à ne limiter la rotation relative entre le bouchon 2 et la bague 3 d'espacement que dans le sens correspondant au vissage du bouchon 2 sur le goulot 11 - conventionnellement le sens horaire et représenté par une flèche sur la
Les ergots 34 s'étendent typiquement dans un plan perpendiculaire à l'axe Z-Z du goulot 11.
Comme on le voit sur la
L'espacement 36 entre les ergots 34 et les logements 35 est dimensionné en fonction des propriétés mécaniques du matériau dont sont formés le bouchon 2 et la bague 3 d'espacement et notamment de ses propriétés de déformation élastique et plastique, de manière à ce que la rotation relative qu'il permet entre le bouchon 2 et la bague 3 entraine une déformation des ponts de matière 31 inférieure à sa résistance à la rupture. Selon un mode de réalisation particulier, l'espacement 36 est égal à 0,5 mm, correspondant donc à la distance entre les ergots 34 et les logements 35 en l'absence de déformation du bouchon 2 et de la bague 3.The
The
As we see on the
The spacing 36 between the
La présente invention permet ainsi de s'assurer de la préservation des ponts de matière 31 reliant le bouchon 2 et la bague 3 d'espacement lors du bouchonnage, ce qui permet ainsi d'assurer la préservation de l'opercule préalablement à la première utilisation du fait de la fonction d'espacement réalisée par la bague permettant de maintenir un espacement entre le poinçon 22 du bouchon 2 et l'opercule de la tête de tube 1.
De plus, l'invention permet d'assurer une fonction de témoin d'ouverture. En effet, lors de la première utilisation, l'utilisateur dévisse le bouchon 2 du goulot 11 ; les reliefs 15 et nervures internes 32 coopèrent alors afin de bloquer la bague 3 d'espacement en rotation.The present invention thus makes it possible to ensure the preservation of the bridges of
In addition, the invention makes it possible to provide an opening control function. Indeed, during the first use, the user unscrews the
La bague 3 d'espacement reste alors immobile tandis que le bouchon 2 est dévissé, ce qui provoque une rupture des ponts de matière 31 et la désolidarisation de la bague 3 par rapport au bouchon 2 et permet ainsi d'identifier aisément un tube ayant déjà été utilisé.The
