Description

DESCRIPTION DESCRIPTION
TITRE : Ensemble pour la fermeture d'un tube et tube comprenant cet ensemble TITLE: Set for closing a tube and tube including this set
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 cover closing the neck prior to the first use of the tube, and a perforating cap suitable for piercing the cover.
On connaît les tubes munis d'un opercule associés à un bouchon perforateur comprenant un poinçon adapté pour perforer ledit opercule. L'opercule est généralement disposé à l'extrémité du goulot en communication fluidique avec le réservoir du tube. L'opercule obture ainsi l'extrémité basse du goulot. Tubes provided with a cover associated with a perforating cap comprising a punch suitable for perforating said cover are known. The cap is generally disposed at the end of the neck in fluid communication with the reservoir of the tube. The cap thus closes the lower end of the neck.
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 cap makes it possible to keep the product contained in the tube hermetically during its storage prior to its first use, which represents a very important part of the overall lifespan of the tube.
Il existe des bouchons dans lesquels le poinçon est disposé dans le bouchon et fait saillie de celui-ci de manière à pouvoir perforer l'opercule lorsque le bouchon est vissé sur la tête de tube. Afin d'assurer la préservation de l'opercule préalablement à la première utilisation, une bague 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. Dans cette position, le bouchon est en position dite de transport ou position d'attente avant la lère utilisation. There are plugs in which the punch is placed in the plug and protrudes therefrom so as to be able to perforate the cover when the plug is screwed onto the tube head. In order to ensure the preservation of the cap prior to the first use, a ring is placed between the cap and the shoulder of the tube head, so as to keep the punch away from the cap when the cap is screwed on. on the neck. In this position, the stopper is in said transport position or standby position before the era use.
Pour percer et/ou découper l'opercule, l'utilisateur doit d'abord dévisser le bouchon, puis enlever la bague et enfin revisser le bouchon jusqu'à ce que l'opercule soit percé et/ou découpé. Le nombre d'étapes est contraignant pour l'utilisateur qui souvent ne comprend pas à quoi sert la bague et ne comprend pas forcément non plus qu'un opercule doit être percé avant une première utilisation du tube. To pierce and / or cut the cap, the user must first unscrew the cap, then remove the ring and finally screw the cap back on until the cap is pierced and / or cut. The number of steps is restrictive for the user who often does not understand what the ring is for and does not necessarily understand either that a cover must be pierced before using the tube for the first time.
Il existe également des bouchons interagissant avec un anneau localisé sur la surface externe du goulot. En position d'attente, l'anneau du goulot est maintenu en position d'attente, à distance de l'opercule. L'anneau du goulot et les excroissances du bouchon constituent un moyen de blocage en position d'attente ne nécessitant pas de pièce rapportée telle que la bague évoqué précédemment. Bien que répondant aux attentes de simplicité d'utilisation, un tel ensemble peut cependant présenter un jeu axial entre le bouchon et le goulot lorsque le bouchon est en position d'attente. Un tel jeu est indésirable pour de nombreuses raisons, notamment de stockage, de manipulation ou de test. There are also plugs interacting with a ring located on the outer surface of the neck. In the standby position, the ring of the neck is held in the standby position, away from the cap. The ring of the neck and the protuberances of the stopper constitute a means of blocking in the standby position which does not require an added part such as the ring mentioned above. Although meeting the expectations of ease of use, such a set may however have axial play between the stopper and the neck when the stopper is in the standby position. Such play is undesirable for many reasons, including storage, handling or testing.
Il existe donc un besoin d'un ensemble pour la fermeture d'un tube qui pallie au moins en partie les inconvénients précités. There is therefore a need for an assembly for closing a tube which at least partially overcomes the aforementioned drawbacks.
A cet effet, la présente invention propose un ensemble pour la fermeture d'un tube, ledit ensemble comprenant : To this end, the present invention provides an assembly for closing a tube, said assembly comprising:
- une tête de tube comprenant un goulot et un opercule obturant ledit goulot, - a tube head comprising a neck and a cap closing off said neck,
- un bouchon comprenant un poinçon adapté pour découper ledit opercule, - a stopper comprising a punch suitable for cutting said cover,
ledit goulot et ledit bouchon étant configurés pour permettre de guider le bouchon d'une position initiale dans laquelle le bouchon n'est pas en prise avec le goulot à une position d'attente dans laquelle le poinçon est maintenu à distance de l'opercule, puis de ladite position d'attente à une position de fermeture dans laquelle ledit poinçon a percé ledit opercule, le bouchon et le goulot définissant un premier chemin de guidage permettant le passage de la position initiale à la position d'attente ainsi que le maintien dans ladite position d'attente, et un second chemin de guidage permettant le passage de la position d'attente à la position de fermeture, lesdits premiers et second chemins de guidage étant indépendant l'un de l'autre. said neck and said stopper being configured to make it possible to guide the stopper from an initial position in which the stopper is not engaged with the neck to a standby position in which the punch is kept at a distance from the cap, then from said standby position to a closed position in which said punch has pierced said cap, the stopper and the neck defining a first guide path allowing passage from the initial position to the standby position as well as the maintenance in said waiting position, and a second guide path allowing the passage from the waiting position to the closed position, said first and second guide paths being independent of one another.
Le fait que le premier et second chemin de guidage soient indépendant l'un de l'autre signifie qu'ils ne sont pas deux portions d'un même chemin de guidage tel qu'un même filetage séparé en deux portions par une cloison transversale mais bien deux chemins distincts. The fact that the first and second guide path are independent of each other means that they are not two portions of the same guide path such as the same thread separated into two portions by a transverse partition but well two distinct paths.
Un tel ensemble permet au bouchon d'être maintenu en position d'attente sans devoir utiliser une pièce supplémentaire autre que le goulot et le bouchon. Autrement dit, l'extrémité libre du poinçon faisant saillie du bouchon est maintenue éloigné de l'opercule obturant le goulot et l'opercule est ainsi préservé de toute perforation ou découpe préalablement à la première utilisation du tube par un utilisateur de manière simple et fiable sans compliquer l'ensemble de fermeture. Notamment un tel ensemble permet de s'abstenir d'utiliser la bague d'espacement généralement utilisée dans de tel système pour maintenir le poinçon éloigné de l'opercule en position d'attente. Le fait que le moyen de blocage en position d'attente soit un chemin de guidage implique une meilleure prise entre le bouchon et le goulot et permet ainsi de limiter le jeu axial entre le bouchon et le goulot lorsque le bouchon est en position d'attente. Such an assembly allows the stopper to be kept in the standby position without having to use an additional part other than the neck and the stopper. In other words, the free end of the punch projecting from the stopper is kept away from the cover closing the neck and the cover is thus preserved from any perforation or cutting prior to the first use of the tube by a user in a simple and reliable manner. without complicating the closing assembly. In particular, such an assembly makes it possible to refrain from using the spacer ring generally used in such a system to keep the punch away from the cover in the standby position. The fact that the locking means in the waiting position is a guide path implies a better grip between the stopper and the neck and thus makes it possible to limit the axial play between the stopper and the neck when the stopper is in the waiting position. .
De plus, le fait que l'ensemble présente deux chemins de guidages indépendants l'un de l'autre permet de limiter encore d'avantage le risque de perforation accidentel de l'opercule. Dans le cas d'un chemin de guidage formé par un filetage séparé en deux portions par une butée située dans le filetage, la deuxième portion du chemin de guidage est dans la continuité de la première portion du chemin de guidage. Si un couple trop important est appliqué au bouchon lors de sa mise en position d'attente, la partie en prise dans la première portion du filetage risque de franchir la butée et de passer directement dans la deuxième portion du filetage. La présence de deux chemins de guidages indépendants l'un de l'autre permet de réduire la continuité de guidage du bouchon et donc de limiter le risque de perforation accidentel de l'opercule. In addition, the fact that the assembly has two guide paths independent of each other makes it possible to further limit the risk of accidental perforation of the cover. In the case of a guide path formed by a thread separated into two portions by a stop located in the thread, the second portion of the guide path is in continuity with the first portion of the guide path. If too much torque is applied to the plug when it is placed in the standby position, the part engaged in the first portion of the thread runs the risk of crossing the stopper and passing directly into the second portion of the thread. The presence of two independent guide paths from one another makes it possible to reduce the continuity of guiding the stopper and therefore to limit the risk of accidental perforation of the cover.

Comme illustré aux différentes figures, l'invention concerne un ensemble 1 pour la fermeture d'un tube, ledit ensemble 1 comprenant une tête de tube 3 et un bouchon 30. La tête de tube 3 comprend un goulot 10 et un opercule 5 obturant ledit goulot 10 en partie basse de ce dernier. En d'autres termes, l'opercule est disposé à l'extrémité du goulot en communication fluidique avec le réservoir du tube. Le bouchon 30 comprend un poinçon 7 adapté pour découper ledit opercule 5. Le goulot 10 et le bouchon 30 s'étendent sensiblement selon un axe longitudinal (A) passant en leur centre. Le bouchon 30 est mobile en rotation et/ou en translation par rapport audit goulot 10 selon ledit axe longitudinal (A). As illustrated in the various figures, the invention relates to an assembly 1 for closing a tube, said assembly 1 comprising a tube head 3 and a stopper 30. The tube head 3 comprises a neck 10 and a cap 5 closing off said neck 10 in the lower part of the latter. In other words, the cap is disposed at the end of the neck in fluid communication with the reservoir of the tube. The stopper 30 comprises a punch 7 adapted to cut said cover 5. The neck 10 and the stopper 30 extend substantially along a longitudinal axis (A) passing through their center. The stopper 30 is movable in rotation and / or in translation with respect to said neck 10 along said longitudinal axis (A).
Ledit goulot 10 et ledit bouchon 30 sont configurés pour permettre de guider le bouchon 30 d'une position initiale à une position d'attente, puis de ladite position d'attente à une position de fermeture. Comme illustré aux figures 4 et 5, lorsque le bouchon 30 est en position initiale, ledit bouchon 30 n'est pas en prise avec le goulot 10. Ledit bouchon 30 est dans cette position initiale au début du mouvement de mise en place du bouchon 30 sur la tête de tube 3. Cette mise en place, également appelé bouchonnage, est en particulier réalisée sur des lignes de productions. Il est donc important de permettre une cinématique simple, fiable et répétable afin de limiter les incidents de production. Avantageusement, lors de la mise en place du bouchon 30 sur la tête de tube 3 de l'ensemble 1 selon l'invention, sur les lignes de productions, le bouchon 30 est simultanément poussé vers la tête de tube et tourné dans le sens contraire des aiguille d'une montre. Said neck 10 and said stopper 30 are configured to allow the stopper 30 to be guided from an initial position to a waiting position, then from said waiting position to a closed position. As illustrated in FIGS. 4 and 5, when the stopper 30 is in the initial position, said stopper 30 is not engaged with the neck 10. Said stopper 30 is in this initial position at the start of the movement for fitting the stopper 30. on the tube head 3. This positioning, also called capping, is carried out in particular on production lines. It is therefore important to allow simple, reliable and repeatable kinematics in order to limit production incidents. Advantageously, when placing the stopper 30 on the tube head 3 of the assembly 1 according to the invention, on production lines, the stopper 30 is simultaneously pushed towards the tube head and turned in the opposite direction. hands of a watch.
Comme illustré aux figures 6 et 7, lorsque le bouchon 30 est en position d'attente sur le goulot 10, le poinçon 7 est maintenu à distance de l'opercule 5. Ledit bouchon 30 est dans cette position d'attente à la fin du mouvement de mise en place du bouchon 30 sur la tête de tube 3. C'est dans cette position qu'est vendu l'ensemble 1 avant remplissage du tube. C'est également dans cette position d'attente qu'est vendu l'ensemble 1 au consommateur, après remplissage du tube. As illustrated in Figures 6 and 7, when the stopper 30 is in the standby position on the neck 10, the punch 7 is maintained at a distance from the cap 5. Said cap 30 is in this standby position at the end of the process. movement of placing the stopper 30 on the tube head 3. It is in this position that the assembly 1 is sold before filling the tube. It is also in this waiting position that the assembly 1 is sold to the consumer, after filling the tube.
Comme illustré aux figures 8 et 9, lorsque le bouchon 30 est en position de fermeture, ledit poinçon 7 a percé ledit opercule 5. Le bouchon 30 ferme alors de manière hermétique le tube 100 sur lequel est adapté l'ensemble 1. La position de fermeture peut également être qualifiée de position d'utilisation dans la mesure où la découpe de l'opercule détermine le point de départ de l'utilisation du tube 100 sur lequel est monté l'ensemble de fermeture 1 selon l'invention. Le bouchon 30 peut en particulier être destiné à rester en position de fermeture. C'est notamment le cas lorsque le poinçon 7 présente la forme d'un fût creux et présente une ouverture 8 au niveau de la face supérieure du bouchon 30. Ainsi, une fois le bouchon 30 en position de fermeture sur le goulot 10, l'accès au volume interne du tube 100 sur lequel est adapté l'ensemble 1 est possible par ladite ouverture 8. As illustrated in Figures 8 and 9, when the cap 30 is in the closed position, said punch 7 has pierced said cap 5. The cap 30 then hermetically closes the tube 100 on which the assembly is fitted 1. The position of closure can also be qualified as a position of use insofar as the cutting of the cover determines the starting point for the use of the tube 100 on which the closure assembly 1 according to the invention is mounted. The stopper 30 may in particular be intended to remain in the closed position. This is particularly the case when the punch 7 has the shape of a hollow barrel and has an opening 8 at the level of the upper face of the stopper 30. Thus, once the stopper 30 is in the closed position on the neck 10, the Access to the internal volume of the tube 100 on which the assembly 1 is fitted is possible through said opening 8.
Avantageusement, lorsque le bouchon 30 est destiné à rester en position de fermeture, la tête de tube 3 comporte une première série de crans 6 coopérant avec une deuxième série de crans 9 du bouchon 30 lorsque ledit bouchon 30 est en position de fermeture. Les deux séries de crans agissent alors comme un système antiretour empêchant le bouchon 30 de retourner en position d'attente. Advantageously, when the stopper 30 is intended to remain in the closed position, the tube head 3 comprises a first series of notches 6 cooperating with a second series of notches 9 of the stopper 30 when said stopper 30 is in the closed position. The two series of notches then act as an anti-return system preventing the stopper 30 from returning to the waiting position.
Selon un mode de réalisation non représenté, l'ouverture 8 du goulot 30 est fermée par un couvercle relié au bouchon 10. Ainsi, le bouchon 30 peut être maintenu en position de fermeture sur le goulot 10 tout en permettant l'accès au volume interne du tube 100 et la fermeture de cet accès. Le bouchon 30 et le goulot 10 définissent ensemble un premier chemin de guidage 21. Ledit premier chemin de guidage 21 permet le passage de la position initiale à la position d'attente. De plus, ledit premier chemin de guidage 21 permet également le maintien du bouchon 30 dans ladite position d'attente. According to an embodiment not shown, the opening 8 of the neck 30 is closed by a cover connected to the stopper 10. Thus, the stopper 30 can be kept in the closed position on the neck 10 while allowing access to the internal volume. tube 100 and the closing of this access. The stopper 30 and the neck 10 together define a first guide path 21. Said first guide path 21 allows the passage from the initial position to the standby position. In addition, said first guide path 21 also allows the stopper 30 to be maintained in said standby position.
Le bouchon 30 et le goulot 10 définissent également ensemble un second chemin de guidage 22. Ledit second chemin de guidage 22 permet le passage de la position d'attente à la position de fermeture. The stopper 30 and the neck 10 also together define a second guide path 22. Said second guide path 22 allows the passage from the waiting position to the closed position.
Le premier chemin de guidage 21 et le second chemin de guidage 22 sont indépendant l'un de l'autre. Ceci signifie que les chemins de guidage sont bien deux chemins distincts et non pas deux portions d'un même chemin de guidage. The first guide path 21 and the second guide path 22 are independent of each other. This means that the guide paths are indeed two distinct paths and not two portions of the same guide path.
Un tel ensemble assure un maintien en position d'attente sans utilisation d'une pièce supplémentaire telle qu'une bague d'espacement. Such an assembly ensures maintenance in the waiting position without the use of an additional part such as a spacer ring.
Le fait que le moyen de blocage en position d'attente soit un chemin de guidage implique une meilleure prise entre le bouchon et le goulot et permet ainsi de limiter le jeu axial entre le bouchon et le goulot lorsque le bouchon est en position d'attente. The fact that the locking means in the waiting position is a guide path implies a better grip between the stopper and the neck and thus makes it possible to limit the axial play between the stopper and the neck when the stopper is in the waiting position. .
De plus, comme mentionné plus haut, le fait que l'ensemble présente deux chemins de guidages indépendants l'un de l'autre permet de limiter encore d'avantage le risque de perforation accidentel de l'opercule. In addition, as mentioned above, the fact that the assembly has two guide paths independent of one another makes it possible to further limit the risk of accidental perforation of the cover.
Les premiers et seconds chemins de guidage de l'ensemble 1 selon l'invention ne sont pas limités aux formes divulguées aux figures 1 à 9. The first and second guide paths of the assembly 1 according to the invention are not limited to the shapes disclosed in Figures 1 to 9.
Avantageusement, l'un des deux entre le premier chemin de guidage 21 et le second chemin de guidage 22 induit une rotation horaire du bouchon 10, l'autre des deux entre le premier chemin de guidage 21 et le second chemin de guidage 22 induit une rotation antihoraire du bouchon 10. Le fait que le passage de la position initiale à la position d'attente soit réalisé par une rotation dans un sens et que le passage de la position d'attente à la position de fermeture soit réalisé par une rotation dans un autre sens permet de limiter encore d'avantage le risque d'un passage accidentel en position de fermeture. En effet, une rotation unique dans un seul sens de rotation ne peut ainsi permettre de passer directement de la position initiale à la position de fermeture. Ceci est particulièrement avantageux lorsque la mise en place du bouchon 30 est réalisée sur des lignes de production. En effet, dans le cas où le passage de la position d'attente à la position de fermeture est réalisable avec un seul sens de rotation, si le couple de rotation de l'unité de bouchonnage est trop élevé par rapport à la résistance plastique de la bague, le bouchon va être vissé au-delà de sa position d'attente et ainsi détériorer la bague et percer l'opercule. En revanche, avec une ensemble 1 selon l'invention nécessitant une rotation dans un sens pour passer de la position initiale à la position d'attente et une rotation dans un sens opposé pour passer de la position d'attente à la position de fermeture, même si le couple de rotation de l'unité de bouchonnage est trop élevé, le risque de passer accidentellement à la position de fermeture, et donc le risque de détérioration du bouchon et le perçage de l'opercule, est fortement limité. Advantageously, one of the two between the first guide path 21 and the second guide path 22 induces a clockwise rotation of the plug 10, the other of the two between the first guide path 21 and the second guide path 22 induces a counterclockwise rotation of the plug 10. The fact that the passage from the initial position to the waiting position is achieved by a rotation in one direction and that the passage from the waiting position to the closed position is achieved by a rotation in another direction makes it possible to further limit the risk of an accidental passage into the closed position. Indeed, a single rotation in a single direction of rotation cannot thus make it possible to pass directly from the initial position to the closed position. This is particularly advantageous when the fitting of the stopper 30 is carried out on production lines. Indeed, in the case where the passage from the standby position to the closure is achievable with only one direction of rotation, if the torque of the capping unit is too high compared to the plastic resistance of the ring, the cap will be screwed in beyond its standby position and thus damage the ring and pierce the seal. On the other hand, with an assembly 1 according to the invention requiring a rotation in one direction to go from the initial position to the waiting position and a rotation in an opposite direction to go from the waiting position to the closed position, even if the rotational torque of the capping unit is too high, the risk of accidentally passing to the closed position, and therefore the risk of deterioration of the stopper and the piercing of the seal, is greatly limited.
De plus, dans le cas d'un bouchon destiné à être retiré du bouchon, ce double sens de rotation est également utile pour sécuriser l'ouverture après la première utilisation, lorsque l'opercule a déjà été découpé. Moreover, in the case of a stopper intended to be removed from the stopper, this double direction of rotation is also useful for securing the opening after the first use, when the cover has already been cut.
Avantageusement encore, le premier chemin de guidage 21 induit une rotation antihoraire du bouchon 10 et le second chemin de guidage 22 induit une rotation horaire du bouchon 10. L'utilisateur réceptionnant l'ensemble 1 en position d'attente n'a alors qu'à réaliser une rotation horaire du bouchon 30 sur le goulot 10 afin de percer l'opercule. La rotation horaire est préférable pour un utilisateur car plus habituelle. Again advantageously, the first guide path 21 induces a counterclockwise rotation of the stopper 10 and the second guide path 22 induces a clockwise rotation of the stopper 10. The user receiving the assembly 1 in the standby position then only has in carrying out a clockwise rotation of the stopper 30 on the neck 10 in order to pierce the cover. Clockwise rotation is preferable for a user because it is more usual.
Préférablement, chaque chemin de guidage est défini par une partie mâle et une partie femelle. La partie mâle du premier chemin de guidage 21 est configurée pour pouvoir interagir avec la partie femelle du premier chemin de guidage 21 uniquement. La partie mâle du premier chemin de guidage 21 ne peut donc pas interagir avec la partie femelle du second chemin de guidage 22 ni avec la partie mâle du second chemin de guidage 22. Preferably, each guide path is defined by a male part and a female part. The male part of the first guide path 21 is configured to be able to interact with the female part of the first guide path 21 only. The male part of the first guide path 21 therefore cannot interact with the female part of the second guide path 22 or with the male part of the second guide path 22.
De la même manière, la partie mâle du second chemin de guidage 22 est configurée pour pouvoir interagir avec la partie femelle du second chemin de guidage 22 uniquement. La partie mâle du second chemin de guidage 22 ne peut donc pas interagir avec la partie femelle du premier chemin de guidage 21 ni avec la partie mâle du premier chemin de guidage 21. Likewise, the male part of the second guide path 22 is configured to be able to interact with the female part of the second guide path 22 only. The male part of the second guide path 22 therefore cannot interact with the female part of the first guide path 21 or with the male part of the first guide path 21.
Cette distinction entre partie mâle et femelle du premier et second chemin de guidage permet d'assurer la séparation entre le mouvement induit par le premier chemin de guidage 21 et le mouvement induit par le second chemin de guidage 22. This distinction between the male and female part of the first and second guide path ensures the separation between the movement induced by the first guide path 21 and the movement induced by the second guide path 22.
Avantageusement, le premier chemin de guidage 21 est défini par une rainure de guidage 11 de l'un des deux entre le goulot 10 et le bouchon 30 interagissant avec un élément en saillie 31 de l'autre des deux entre le goulot 10 et le bouchon 30. Ainsi, la partie femelle du premier chemin de guidage 21 correspond à la rainure de guidage 11 et la partie mâle dudit premier chemin de guidage 21 correspond à l'élément en saillie 31. Advantageously, the first guide path 21 is defined by a guide groove 11 of one of the two between the neck 10 and the stopper 30 interacting with a projecting element 31 of the other of the two between the neck 10 and the stopper 30. So the female part of the first path guide 21 corresponds to the guide groove 11 and the male part of said first guide path 21 corresponds to the projecting element 31.
De la même manière, le deuxième chemin de guidage 22 est défini par un premier filetage 16 de l'un des deux entre le goulot 10 et le bouchon 30 interagissant avec un second filetage 36 de l'autre des deux entre le goulot 10 et le bouchon 30. Ainsi, la partie femelle du second chemin de guidage 22 correspond au premier filetage et la partie mâle dudit second chemin de guidage 22 correspond au second filetage 36. Likewise, the second guide path 22 is defined by a first thread 16 of one of the two between the neck 10 and the stopper 30 interacting with a second thread 36 of the other of the two between the neck 10 and the plug 30. Thus, the female part of the second guide path 22 corresponds to the first thread and the male part of said second guide path 22 corresponds to the second thread 36.
Les parties mâles et femelles des premiers et seconds chemins de guidage de l'ensemble 1 selon l'invention ne sont pas limitées aux formes divulguées aux figures 1 à 9. The male and female parts of the first and second guideways of the assembly 1 according to the invention are not limited to the shapes disclosed in Figures 1 to 9.
Avantageusement, comme représenté aux figures 1 à 10, le goulot 10 comprend la rainure de guidage 11 et le premier filetage 16. Ainsi, le bouchon 30 comprend l'élément en saillie 31 et le second filetage 36. Advantageously, as shown in Figures 1 to 10, the neck 10 comprises the guide groove 11 and the first thread 16. Thus, the plug 30 comprises the projecting element 31 and the second thread 36.
Préférentiellement, le goulot comprend trois rainures de guidage 11 régulièrement réparties sur sa face externe. Preferably, the neck comprises three guide grooves 11 regularly distributed over its external face.
Avantageusement encore, le bouchon comprend trois éléments en saillie 31. Lesdits éléments en saillie 31 sont régulièrement répartis sur la face interne du bouchon 30. Again advantageously, the stopper comprises three projecting elements 31. Said projecting elements 31 are regularly distributed over the internal face of the stopper 30.
Selon un autre mode de réalisation non représenté, la rainure de guidage 11 et le premier filetage 16 peuvent être localisés sur le bouchon 30. Dans cette configuration, l'élément en saillie 31 et le second filetage 36 sont localisés sur le goulot 10. According to another embodiment not shown, the guide groove 11 and the first thread 16 can be located on the stopper 30. In this configuration, the projecting element 31 and the second thread 36 are located on the neck 10.
Avantageusement encore, comme représenté aux figures 1 et 2, la rainure de guidage 11 est située dans une partie basse du goulot 10, c'est-à-dire la partie du goulot partant de son extrémité inférieure en communication fluidique avec le réservoir du tube. Le premier filetage 16 est quant à lui situé dans une partie haute dudit goulot 10, c'est-à-dire la partie du goulot partant de son extrémité supérieure en communication avec l'extérieur du tube. Dans cette configuration, l'élément en saillie 31 est situé dans une partie basse du bouchon 30 et le second filetage 36 est situé dans une partie haute dudit bouchon 30, de sorte à pouvoir interagir respectivement avec la rainure de guidage 11 et le premier filetage 16. Une telle disposition permet une meilleure stabilisation du bouchon 30 en position d'attente. Again advantageously, as shown in Figures 1 and 2, the guide groove 11 is located in a lower part of the neck 10, that is to say the part of the neck starting from its lower end in fluid communication with the reservoir of the tube. . The first thread 16 is for its part located in an upper part of said neck 10, that is to say the part of the neck starting from its upper end in communication with the outside of the tube. In this configuration, the projecting element 31 is located in a lower part of the plug 30 and the second thread 36 is located in an upper part of said plug 30, so as to be able to interact respectively with the guide groove 11 and the first thread. 16. Such an arrangement allows better stabilization of the stopper 30 in the standby position.
Dans la mesure où le premier chemin de guidage 21 induit une rotation antihoraire du bouchon 10 et le second chemin de guidage 22 induit une rotation horaire du bouchon 10, la rainure de guidage 11 présente un sens rétrograde et les premier et second filetages 16, 36 présentent un pas à droite. Insofar as the first guide path 21 induces a counterclockwise rotation of the cap 10 and the second guide path 22 induces a clockwise rotation of the cap 10, the groove of guide 11 has a retrograde direction and the first and second threads 16, 36 have a right pitch.
Comme représenté aux figures 1 et 2, le premier filetage 16 est formé par une pluralité de filetsAs shown in Figures 1 and 2, the first thread 16 is formed by a plurality of threads
17 s'étendant depuis une face externe du goulot 10 et présentant un bord distal 18. La rainure de guidage 11 est quant à elle formée par une pluralité de nervures 12 s'étendant depuis une face externe du goulot 10 et présentant un bord distal 13. Avantageusement, la nervure 12 comprend une portion 12a formant une rampe hélicoïdale et une portion 12b coudée. 17 extending from an outer face of the neck 10 and having a distal edge 18. The guide groove 11 is itself formed by a plurality of ribs 12 extending from an outer face of the neck 10 and having a distal edge 13 Advantageously, the rib 12 comprises a portion 12a forming a helical ramp and a bent portion 12b.
Avantageusement encore, le goulot 10 comprend trois nervures 12 à 120° l'une de l'autre. Les nervures 12 sont ainsi régulièrement réparties sur la face externe du goulot 10. Also advantageously, the neck 10 comprises three ribs 12 at 120 ° from each other. The ribs 12 are thus regularly distributed over the external face of the neck 10.
Préférentiellement, le bord distal 13 des nervures 12 est radialement décalé par rapport audit bord distal 18 des filets 17. Ce décalage radial permet d'éviter toute interférence d'une part entre l'élément en saillie 31 et les filets 17 du premier filetage 16 et d'autre part entre les nervures 12 et le second filetage 36. Preferably, the distal edge 13 of the ribs 12 is radially offset with respect to said distal edge 18 of the threads 17. This radial offset makes it possible to avoid any interference on the one hand between the projecting element 31 and the threads 17 of the first thread 16. and on the other hand between the ribs 12 and the second thread 36.
Dans cette configuration, l'élément en saillie 31 et le second filetage 36 du bouchon 30 sont également décalés radialement l'un par rapport à l'autre de sorte à pouvoir interagir respectivement avec la rainure de guidage 11 et le premier filetage 16. In this configuration, the projecting element 31 and the second thread 36 of the plug 30 are also radially offset with respect to each other so as to be able to interact respectively with the guide groove 11 and the first thread 16.
Comme illustré aux figures 1 et 2, le goulot 10 s'étend le long d'un axe longitudinal (A) passant en son centre. Avantageusement, la distance radiale entre le bord distal 13 des nervures 12 et ledit axe longitudinal (A) est supérieure à la distance radiale entre le bord distal 18 des filets 17 et ledit axe longitudinal (A). En d'autres termes, les nervures 12 présentent une plus grande hauteur ou profondeur par rapport aux filets 17 du premier filetage 16. Les nervures 12 sont ainsi décalées radialement vers l'extérieur du goulot 10 par rapport aux filets 17 du premier filetage 16. As illustrated in Figures 1 and 2, the neck 10 extends along a longitudinal axis (A) passing through its center. Advantageously, the radial distance between the distal edge 13 of the ribs 12 and said longitudinal axis (A) is greater than the radial distance between the distal edge 18 of the threads 17 and said longitudinal axis (A). In other words, the ribs 12 have a greater height or depth relative to the threads 17 of the first thread 16. The ribs 12 are thus offset radially outwardly of the neck 10 with respect to the threads 17 of the first thread 16.
Dans cette configuration, l'élément en saillie 31 est lui aussi décalé radialement vers l'extérieur du bouchon 30 par rapport aux filets du second filetage 36. En particulier, comme représenté aux figures 11 et 12, le diamètre minimum d31 du cercle défini par le bord des éléments en saillie 31 est supérieur au diamètre maximum dl6 du premier filetage 16 défini par le bord distal In this configuration, the projecting element 31 is itself also offset radially towards the outside of the plug 30 relative to the threads of the second thread 36. In particular, as shown in Figures 11 and 12, the minimum diameter d31 of the circle defined by the edge of the protruding elements 31 is greater than the maximum diameter dl6 of the first thread 16 defined by the distal edge
18 des filets 17. En revanche, le diamètre externe dl2 du cercle défini par le bord distal 13 des nervures 12 est supérieur au diamètre minimum du cercle défini par le bord des éléments en saillie 31. 18 of the threads 17. On the other hand, the outer diameter dl2 of the circle defined by the distal edge 13 of the ribs 12 is greater than the minimum diameter of the circle defined by the edge of the projecting elements 31.
De cette manière, lorsque le bouchon 30 est monté sur le goulot 10 et se déplace en translation le long de l'axe longitudinal (A), l'élément en saillie 31 vient au contact d'une nervure 12 sans entrer en contact avec les filets 17 du premier filetage 16 du goulot 10. Il n'y a donc aucune interférence entre l'élément en saillie 31 et le premier filetage 16. In this way, when the stopper 30 is mounted on the neck 10 and moves in translation along the longitudinal axis (A), the projecting element 31 comes into contact with a rib 12 without come into contact with the threads 17 of the first thread 16 of the neck 10. There is therefore no interference between the projecting element 31 and the first thread 16.
Une première manière de permettre le décalage radial entre les nervures 12 et les filets 17 est donc de faire varier leur hauteur ou profondeur. Selon un autre mode de réalisation représenté à la figure 10, la largeur ou diamètre du goulot 10 au niveau du premier filetage 16 est inférieure à la largeur ou diamètre du goulot 10 au niveau de la rainure de guidage 11. Ainsi, même avec des nervures et des filets 17 de hauteur identique, les nervures 12 sont radialement décalées par rapport aux filets 17. Cette configuration permet notamment une fabrication simplifiée. Ce mode de réalisation est particulièrement avantageux en ce qui concerne le démoulage du goulot lors de sa fabrication. En effet, le décalage radial entre la partie haute et la partie basse du goulotA first way of allowing the radial offset between the ribs 12 and the threads 17 is therefore to vary their height or depth. According to another embodiment shown in FIG. 10, the width or diameter of the neck 10 at the level of the first thread 16 is less than the width or diameter of the neck 10 at the level of the guide groove 11. Thus, even with ribs and threads 17 of identical height, the ribs 12 are radially offset with respect to the threads 17. This configuration allows in particular a simplified manufacture. This embodiment is particularly advantageous as regards the release from the mold of the neck during its manufacture. Indeed, the radial offset between the upper part and the lower part of the neck
10 permet de faciliter le démoulage dudit goulot 10. 10 makes it possible to facilitate the demolding of said neck 10.
En pratique, lors de la fabrication d'un goulot 10 selon le mode de réalisation des figures 1 à 9, le goulot 10 subit un démoulage en force par rotation du moule. Cette rotation est susceptible d'endommager la nervure 12. In practice, during the manufacture of a neck 10 according to the embodiment of FIGS. 1 to 9, the neck 10 undergoes a force-release by rotation of the mold. This rotation is liable to damage the rib 12.
En revanche, le mode de réalisation de la figure 10 est formé par un moule comprenant une partie haute formant le filetage 16 de la partie haute du goulot 10 et une partie basse formant la nervure 12 de la partie basse du goulot. Lors du démoulage, la partie haute du moule est retiré par rotation, ce qui n'endommage pas le filetage 16, et la partie basse du moule est retiré en force par un mouvement de translation. Ce retrait en force par un mouvement de translation permet de réduire le risque d'endommager la nervure 12. On the other hand, the embodiment of FIG. 10 is formed by a mold comprising an upper part forming the thread 16 of the upper part of the neck 10 and a lower part forming the rib 12 of the lower part of the neck. During demolding, the upper part of the mold is removed by rotation, which does not damage the thread 16, and the lower part of the mold is forcefully removed by a translational movement. This forced withdrawal by a translational movement reduces the risk of damaging the rib 12.
Le maintien du bouchon 30 en position d'attente peut être réalisé par une pluralité de formes différentes. Avantageusement, la rainure de guidage 11 comprend des protubérances 14 dudit goulot 10 pour maintenir ledit bouchon 30 en position d'attente. Comme représenté à la figure 2, chaque nervure 12 peut comprendre une pluralité de protubérances. Lesdites nervures 12 ici représentées comportent deux protubérances 14a et 14b, mais le nombre, la forme et la disposition des protubérances 14 n'est nullement limitée à celles divulguées par les figures. De telles protubérances constituent un obstacle partiel pour le passage de l'élément en saillie 31 dans la rainure de guidage 11. Le passage de l'élément en saillie 31 dans la rainure de guidageMaintaining the stopper 30 in the waiting position can be achieved by a plurality of different shapes. Advantageously, the guide groove 11 comprises protrusions 14 of said neck 10 to maintain said stopper 30 in the standby position. As shown in Figure 2, each rib 12 may include a plurality of protuberances. Said ribs 12 shown here have two protuberances 14a and 14b, but the number, shape and arrangement of protuberances 14 is in no way limited to those disclosed by the figures. Such protuberances constitute a partial obstacle for the passage of the protruding element 31 in the guide groove 11. The passage of the protruding element 31 in the guide groove
11 au niveau d'une protubérance 14 induit une certaine résistance. 11 at the level of a protuberance 14 induces a certain resistance.
Comme illustré à la figure 2, les protubérances 14 s'étendent avantageusement des bords des nervures 12. Une telle configuration des protubérances 14 permet notamment une fabrication simplifiée. Avantageusement encore, les protubérances 14 sont configurées de sorte à induire une résistance lorsque le bouchon 30 arrive en position d'attente et une résistance supérieure lorsque le bouchon 30 sort de la position d'attente vers la position de fermeture. As illustrated in FIG. 2, the protuberances 14 advantageously extend from the edges of the ribs 12. Such a configuration of the protuberances 14 allows in particular a simplified manufacture. Again advantageously, the protuberances 14 are configured so as to induce a resistance when the stopper 30 arrives in the waiting position and a higher resistance when the stopper 30 leaves the waiting position towards the closed position.
Le passage d'une première protubérance 14a permet la mise en place du bouchon 30 en position d'attente. Lorsque l'élément en saillie 31 franchit la première protubérance 14a, ledit élément en saillie vient au contact de la portion coudée 12b de la nervure 12. Le bouchon 30 est alors en position d'attente. Ladite première protubérance 14a et ladite portion coudée 12b forment ensemble un logement accueillant ledit élément en saillie 31 lorsque le bouchon 30 est en position d'attente. Ainsi, la première protubérance 14a rencontrée par l'élément en saillie 31 permet à la fois de s'assurer de la mise en place du bouchon 30 en position d'attente et permet d'éviter un retour accidentel en position initiale. Lorsque l'élément en saillie est en position d'attente, le premier filetage 16 et le second filetage 36 ne sont pas encore en prise l'un avec l'autre. The passage of a first protuberance 14a allows the fitting of the stopper 30 in the standby position. When the projecting element 31 crosses the first protrusion 14a, said projecting element comes into contact with the bent portion 12b of the rib 12. The stopper 30 is then in the standby position. Said first protuberance 14a and said angled portion 12b together form a housing accommodating said protruding element 31 when stopper 30 is in the standby position. Thus, the first protuberance 14a encountered by the projecting element 31 makes it possible both to ensure that the stopper 30 is put in place in the standby position and to prevent an accidental return to the initial position. When the protruding member is in the standby position, the first thread 16 and the second thread 36 are not yet engaged with each other.
Le passage d'une seconde protubérance 14b permet le passage de la position d'attente à la position de fermeture. Lorsque l'élément en saillie 31 franchit la seconde protubérance 14b, ledit élément en saillie se dégage de la portion coudée 12b de la nervure 12 et le second filetage 36 du bouchon vient en prise avec le premier filetage du goulot 30. La seconde protubérance 14b permet d'éviter un passage accidentel en position de fermeture et donc un découpage accidentel de l'opercule. La découpe de l'opercule représente un aspect critique du stockage de produit dans le tube sur lequel est monté l'ensemble de fermeture, il est donc préférable de sécuriser d'avantage le passage en position de fermeture, en l'occurrence par une protubérance induisant une résistance plus importante. Une telle configuration permet donc un montage du bouchon 30 sur le goulot 10 et un maintien sécurisé en position d'attente. The passage of a second protuberance 14b allows the passage from the waiting position to the closed position. When the protruding member 31 passes the second protrusion 14b, said protruding member disengages from the bent portion 12b of the rib 12 and the second thread 36 of the stopper engages the first thread of the neck 30. The second protuberance 14b makes it possible to prevent accidental passage into the closed position and therefore accidental cutting of the cover. The cutting of the cover represents a critical aspect of the storage of product in the tube on which the closure assembly is mounted, it is therefore preferable to further secure the passage in the closed position, in this case by a protuberance inducing greater resistance. Such a configuration therefore allows mounting of the stopper 30 on the neck 10 and secure maintenance in the waiting position.
Préférentiellement, la rainure 11 présente des portions de guidage successives. Au moins une première portion lia assure le passage de la position initiale à la position d'attente. Au moins une deuxième portion 11b permet au second filetage 36 d'entrer en prise avec le premier filetage 16. La portion coudée 12b assure donc également un positionnement du second filetage 36 par rapport au premier filetage 16 de sorte que, lors de la lere utilisation, le second filetage 36 s'engage correctement dans le premier filetage 16 et que l'utilisateur ne ressente pas une sensation d'accrochage ou de blocage si le second filetage 36 butait contre le premier filetage 16 par un mauvais positionnement. La rainure 11 est formée entre deux nervures 12 voisines. La rainure 11 présente en particulier une première ouverture permettant le passage en position d'attente et une deuxième ouverture permettant le passage en position de fermeture. La première ouverture est formée entre l'extrémité de la portion 12a hélicoïdale d'une première nervure 12 et la partie haute de la portion 12b coudée d'une deuxième nervure 12. La deuxième ouverture est quant à elle formée entre l'extrémité de la portion 12a hélicoïdale d'une première nervure 12 et la partie basse de la portion 12b coudée d'une deuxième nervure 12. Ainsi, lorsque le bouchon 30 passe en position d'attente, un élément en saillie 31 passe par la première ouverture de la rainure 11 et vient se loger au creux de la portion 12b coudée de la nervure 12. Lorsque le bouchon 30 passe en position de fermeture, élément en saillie 31 se déloge du creux de la portion 12b coudée et passe par la deuxième ouverture de la rainure 11. Preferably, the groove 11 has successive guide portions. At least a first portion 11a ensures the passage from the initial position to the standby position. At least a second portion 11b allows the second thread 36 to engage with the first thread 16. The angled portion 12b therefore also ensures a positioning of the second thread 36 relative to the first thread 16 so that, during the 1st In use, the second thread 36 engages correctly in the first thread 16 and that the user does not feel a hooking or locking sensation if the second thread 36 abuts against the first thread 16 by a bad positioning. The groove 11 is formed between two neighboring ribs 12. The groove 11 has in particular a first opening allowing passage to the standby position and a second opening allowing passage to the closed position. The first opening is formed between the end of the helical portion 12a of a first rib 12 and the upper part of the angled portion 12b of a second rib 12. The second opening is in turn formed between the end of the helical portion 12a of a first rib 12 and the lower part of the angled portion 12b of a second rib 12. Thus, when the stopper 30 passes into the standby position, a projecting element 31 passes through the first opening of the groove 11 and comes to be housed in the hollow of the bent portion 12b of the rib 12. When the plug 30 passes into the closed position, the projecting element 31 dislodges from the hollow of the bent portion 12b and passes through the second opening of the groove 11.
Avantageusement, la première portion lia induit une rotation antihoraire du bouchon 30 et la deuxième portion 11b induit une rotation horaire du bouchon 30. Advantageously, the first portion 11a induces an anti-clockwise rotation of the plug 30 and the second portion 11b induces a clockwise rotation of the plug 30.
Les figures 4 à 9 représentent un ensemble de fermeture 1 selon la présente invention, et ce en position initiale, en position d'attente et en position de fermeture. Figures 4 to 9 show a closure assembly 1 according to the present invention, in the initial position, in the waiting position and in the closed position.
Comme illustré à la figure 4, lorsque le bouchon 30 est en position initiale sur le goulot 10, chaque élément en saillie 31 vient au contact d'une partie haute de la portion 12a hélicoïdale d'une des nervures 12 de la rainure 11. Dans cette position, le premier filetage 16 et le second filetage 36 ne sont pas en prise l'un avec l'autre. Comme représenté à la figure 5, dans cette position initiale le poinçon 7 du bouchon 10 est à distance de l'opercule 5 de la tête de tube 3. As illustrated in FIG. 4, when the stopper 30 is in the initial position on the neck 10, each projecting element 31 comes into contact with an upper part of the helical portion 12a of one of the ribs 12 of the groove 11. In in this position, the first thread 16 and the second thread 36 do not engage with each other. As shown in Figure 5, in this initial position the punch 7 of the stopper 10 is at a distance from the cap 5 of the tube head 3.
Lors du passage de la position initiale à la position d'attente illustrée à la figure 6, le bouchon 30 subit une rotation antihoraire par rapport au goulot 10 et l'élément en saillie 31 du bouchon 30 glisse le long de portion 12a hélicoïdale de la nervure 12, dans l'une des premières portions lia de la rainure 11. Ledit élément en saillie 31 dépasse alors l'une des protubérances 14, en l'occurrence la première protubérance 14a, et passe par la première ouverture de la rainure 11 de sorte à venir en butée contre le creux de la portion 12b coudée de la nervure 12. Le dépassement de la protubérance 14a nécessite un certain effort. La portion 12b coudée de la nervure 12 empêche de poursuivre la rotation antihoraire du bouchon 30. Les protubérances 14 empêchent quant à elle une rotation horaire accidentelle du bouchon 30 pour revenir en position initiale ou pour passer en position de fermeture. Le bouchon 30 est ainsi maintenu en position d'attente par la rainure 11 et par les protubérances 14. Dans cette position, le premier filetage 16 et le second filetage 36 ne sont toujours pas en prise l'un avec l'autre. Comme représenté à la figure 7, dans cette position d'attente le poinçon 7 du bouchon 10 est à une distance réduite de l'opercule 5 de la tête de tube 3. Lors du passage de la position d'attente à la position de fermeture illustré à la figure 8, le bouchon 30 subit une rotation horaire par rapport au goulot 10 et l'élément en saillie 31 du bouchon 30 glisse le long de la portion coudée 12b de la nervure 12, dans l'une des secondes portions 11b de la rainure 11. Ledit élément en saillie 31 dépasse alors une protubérance 14, en l'occurrence la deuxième protubérance 14b et passe par la deuxième ouverture de la rainure 11. Le dépassement de la protubérance 14b nécessite un effort plus important que pour la première protubérance 14a. Lors du dépassement de ladite deuxième protubérance 14b, le poinçon 7 entame un percement de l'opercule 5. Simultanément, le premier filetage 16 et le second filetage 36 entrent en prise l'un avec l'autre. Le premier filetage 16 va alors guider le bouchon 30 jusqu'à atteindre la position de fermeture. Le bouchon subit alors une rotation horaire par rapport au goulot 10 et le poinçon 7 découpe l'opercule 5. Comme représenté à la figure 9, dans cette position de fermeture l'opercule 5 de la tête de tube 3 est découpé par le poinçon 7 du bouchon 10. Avantageusement, ledit opercule est seulement partiellement découpé. Comme illustré à la figure 13, la présente invention concerne également un tube 100 comprenant un ensemble 1 de fermeture tel que décrit ci-dessus. When passing from the initial position to the standby position illustrated in FIG. 6, the stopper 30 undergoes a counterclockwise rotation with respect to the neck 10 and the protruding member 31 of the stopper 30 slides along the helical portion 12a of the rib 12, in one of the first portions 11a of the groove 11. Said projecting element 31 then projects beyond one of the protuberances 14, in this case the first protuberance 14a, and passes through the first opening of the groove 11 of so as to come into abutment against the hollow of the bent portion 12b of the rib 12. The protrusion of the protuberance 14a requires a certain effort. The bent portion 12b of the rib 12 prevents continued anti-clockwise rotation of the stopper 30. The protuberances 14 prevent accidental clockwise rotation of the stopper 30 to return to the initial position or to pass into the closed position. The stopper 30 is thus held in the waiting position by the groove 11 and by the protuberances 14. In this position, the first thread 16 and the second thread 36 are still not engaged with each other. As shown in Figure 7, in this standby position the punch 7 of the stopper 10 is at a reduced distance from the cap 5 of the tube head 3. When passing from the standby position to the closed position illustrated in Figure 8, the stopper 30 undergoes a clockwise rotation with respect to the neck 10 and the projecting element 31 of the stopper 30 slides along the bent portion 12b of the rib 12, in one of the second portions 11b of the groove 11. Said protruding element 31 then projects beyond a protuberance 14, in this case the second protuberance 14b and passes through the second opening of the groove 11. The protrusion of the protrusion 14b requires a greater force than for the first protuberance 14a. When passing said second protuberance 14b, the punch 7 begins to pierce the cover 5. Simultaneously, the first thread 16 and the second thread 36 come into engagement with one another. The first thread 16 will then guide the stopper 30 until it reaches the closed position. The stopper then undergoes a clockwise rotation with respect to the neck 10 and the punch 7 cuts the cover 5. As shown in FIG. 9, in this closed position the cover 5 of the tube head 3 is cut by the punch 7. of the stopper 10. Advantageously, said cover is only partially cut. As illustrated in FIG. 13, the present invention also relates to a tube 100 comprising a closure assembly 1 as described above.
