Abstract

The invention relates to a closure and container assembly having a neck, comprising complementary snap-fit means, characterised in that the neck has two successive snap-fit means having between them an annular groove carrying, set back, several embossings (20), which are uneven in number or a multiple of an uneven number, each having at least on one and the same side, to the left or to the right, a lateral bearing edge (21, 22) with one and the same tilt relative to the axis of the neck, the inside of the said closure having embossings (13) which snap fit into the said groove and, after possible rotation of the said closure, interact simultaneously with the said bearing edges (21, 22) of the embossings (20) of the said groove, giving rise to a downward translational movement of the said closure and its definitive snap-fitting. The invention applies to any closure fixed in a tamper-evident manner onto the neck of a container, in particular capsules with a shaft or "service capsules". <IMAGE>

Description

L'invention concerne le domaine des bouchages fixés de façon inviolable sur le goulot d'un récipient.The invention relates to the field of closures fixed in an inviolable manner on the neck of a container.

On connaît des capsules à ouverture en matière plastique dont la base ou souche est fixée sur le goulot en matière plastique d'un tube typiquement par encliquetage, cette base comportant un moyen d'étanchéité par l'intérieur dudit goulot, par exemple une couronne pénétrant avec forcement à l'intérieur de ce goulot. Cette base est fixée sur le goulot par vissage ou simple encliquetage, d'inviolabilité médiocre.Plastic opening capsules are known, the base or strain of which is fixed to the plastic neck of a tube typically by snap-fastening, this base comprising a sealing means from the inside of said neck, for example a penetrating crown. with forcing inside this neck. This base is fixed to the neck by screwing or simple snap-fastening, of poor inviolability.

On connaît par ailleurs, par les brevets EP-B-192011 et EP-B-0119145 de la demanderesse, un capuchon comportant des moyens d'emboîtage axial à force d'un opercule d'inviolabilité qui surmonte le goulot d'un récipient. Ces moyens d'emboîtage sont des ailettes radiales d'entaillage longitudinal en matière plastique plus dure que celle dudit opercule, ou des ailettes d'emboîtage de reliefs longitudinaux de l'opercule.We also know, from patents EP-B-192011 and EP-B-0119145 of the applicant, a cap comprising means of axial interlocking by force of a tamper-evident seal which overcomes the neck of a container. These nesting means are radial fins of longitudinal notching made of plastic material harder than that of said cover, or fins of longitudinal relief reliefs of the cover.

La demanderesse a cherché à mettre au point un bouchage emboîtant le goulot d'un récipient comportant des moyens de fixation de sécurité accrue et s'est préoccupée de l'adaptation de tels moyens au cas d'une capsule à ouverture et d'un goulot à opercule d'inviolabilité.The Applicant has sought to develop a closure fitting the neck of a container comprising increased safety fixing means and is concerned with the adaptation of such means to the case of an opening capsule and a neck. with tamper-evident seal.

EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention a pour objet l'ensemble d'un bouchage et d'un récipient à goulot, ledit bouchage et ledit récipient comportant des moyens complémentaires d'encliquetage, caractérisé en ce que ledit goulot comporte un premier moyen d'encliquetage et en dessous un deuxième moyen d'encliquetage consistant en un jonc d'arrêt, ledit premier moyen d'encliquetage et ledit jonc d'arrêt ayant entre eux une gorge portant en retrait plusieurs reliefs locaux de nombre supérieur ou égal à 3 ayant chacun au moins d'un même côté à gauche ou à droite un bord d'appui latéral d'une même inclinaison par rapport à l'axe dudit goulot, l'intérieur dudit bouchage ayant des reliefs locaux qui s'encliquetent dans ladite gorge et après éventuelle rotation dudit bouchage coopèrent simultanément avec lesdits bords d'appui des reliefs de ladite gorge en entraînant un mouvement vers le bas consistant en ou voisin d'une translation dudit bouchage et son encliquetage en-dessous dudit jonc d'arrêt. Le bouchage peut alors tourner librement autour du goulot.The subject of the invention is the assembly of a closure and a container with a neck, said closure and said container comprising complementary latching means, characterized in that said neck comprises a first latching means and below a second latching means consisting of a stop ring, said first latching means and said stop ring having between them a groove recessing several local reliefs of number greater than or equal to 3 each having at least the same side to the left or to the right a lateral bearing edge of the same inclination relative to the axis of said neck, the interior of said closure having local reliefs which engage in said groove and after possible rotation of said stopper cooperate simultaneously with said bearing edges of the reliefs of said groove by causing a downward movement consisting of or near a translation of said stopper and its snap-in below said stop ring . The closure can then rotate freely around the neck.

Le fonctionnement de l'enfoncement du bouchage et de sa fixation en deux étapes peut être expliqué comme suit : les moyens d'encliquetage de l'intérieur du bouchage, typiquement une jupe, sont ses reliefs locaux qui jouent aussi un rôle pour l'enfoncement du bouchage au-delà du jonc d'arrêt. Au premier encliquetage, chacun de ces reliefs vient se loger au hasard dans la gorge du goulot, soit contre une portion de relief local du goulot lui-même en retrait dans cette gorge, soit dans un intervalle entre reliefs locaux. Pour enfoncer davantage le bouchage vers sa position de délivrance d'un produit contenu, il suffit d'une faible rotation de ce bouchage, en tous cas inférieure à 120°, dans un sens repéré s'il s'agit de reliefs locaux à bords d'appui seulement à droite ou à gauche, pour que la descente du bouchage et son encliquetage sous le jonc d'arrêt se produisent sous deux effets : brusque glissement simultané des reliefs locaux du bouchage contre les reliefs locaux du goulot amorçant le franchissement du jonc d'arrêt, ce franchissement étant alors effectué avec un appui très faible, le guidage équilibré du glissement précédent et une légère déformation de la jupe ou couronne du bouchage facilitant ce franchissement. La position ainsi obtenue est fortement inviolable, elle s'applique à divers bouchages fixés sur le goulot d'un récipient, qu'ils soient associés à un moyen d'étanchéité distinct ou non, et à couper, percer ou ouvrir pour la délivrance du produit contenu. Pour la réussite de la descente facile du bouchage lors de son encliquetage définitif, il est important que les reliefs locaux coopèrent par glissement de façon simultanée, ce qui implique en pratique et de préférence qu'ils soient régulièrement espacés, ces conditions assurant le bon maintien du bouchage selon l'axe du goulot. Le nombre supérieur ou égal à 3 et de préférence impair des reliefs locaux du goulot permet un bon équilibrage ou maintien du bouchage en toute position de descente. Les nombres impairs supérieurs ou égaux à 3 ainsi préférés assurent en effet une stabilité axiale meilleure que les nombres pairs, grâce à la dissymétrie diamétrale constante de leurs zones d'appui (pas de petit effet de basculement).The operation of driving in the plug and fixing it in two stages can be explained as follows: the latching means inside the plug, typically a skirt, are its local reliefs which also play a role in driving in plugging beyond the stop ring. At the first click, each of these reliefs is housed at random in the throat of the neck, either against a portion of local relief of the neck itself recessed in this groove, or in an interval between local reliefs. To push the stopper further towards its delivery position for a contained product, it suffices for a slight rotation of this stopper, in any case less than 120 °, in a marked direction if it is local reliefs with edges support only on the right or on the left, so that the descent of the stopper and its snapping under the stop ring occur under two effects: sudden simultaneous sliding of the local reliefs of the stopper against the local reliefs of the neck initiating the crossing of the rush stopping, this crossing being then carried out with very little support, the balanced guidance of the preceding sliding and a slight deformation of the skirt or crown of the blocking facilitating this crossing. The position thus obtained is highly inviolable, it applies to various closures fixed on the neck of a container, whether they are associated with a separate sealing means or not, and to cut, pierce or open for the delivery of the content product. For the success of the easy descent of the stopper during its final snap-on, it is important that the local reliefs cooperate by sliding simultaneously, which implies in practice and preferably that they are regularly spaced, these conditions ensuring good maintenance plugging along the axis of the neck. The number greater than or equal to 3 and preferably odd of the local reliefs of the neck allows a good balancing or maintenance of the blockage in any descent position. The odd numbers greater than or equal to 3 thus preferred indeed provide better axial stability than the even numbers, thanks to the constant diametrical asymmetry of their bearing zones. (no small tilting effect).

De préférence, les reliefs locaux du goulot comportent des bords d'appui à gauche et à droite, lesdits reliefs locaux du bouchage coopérant soit avec lesdits bords d'appui à gauche, soit avec lesdits bords d'appui à droite selon le sens de rotation du bouchage.Preferably, the local reliefs of the neck have support edges on the left and on the right, said local relief reliefs cooperating either with said support edges on the left, or with said support edges on the right according to the direction of rotation. clogging.

Plus précisément, les bords d'appui desdits reliefs locaux de la gorge annulaire du récipient et de l'intérieur du bouchage sont de préférence respectivement perpendiculaires à leurs surfaces. Ce sont alors des petits bords latéraux abrupts de ces reliefs locaux respectifs de la gorge du récipient et de la surface intérieure du bouchage, dont la mise en contact provoque une réaction vers le bas qui fait descendre le bouchage. Les reliefs locaux de chaque surface sont espacés autour de l'axe longitudinal du goulot et du bouchage, leurs bords d'appui respectifs étant à un même niveau par rapport à cet axe de façon à remplir simultanément leur rôle d'entraînement vers le bas du bouchage. La règle pratique de nombre de reliefs locaux du goulot s'adresse en réalité au nombre de ses bords d'appui agissant dans un enfoncement du bouchage: ainsi trois reliefs locaux ayant chacun un bord d'appui à gauche et un bord d'appui à droite pourront, si les reliefs locaux de l'intérieur du bouchage présentent des bords d'appui correspondants, permettre un enfoncement du bouchage selon l'invention soit en légère rotation à droite, soit en légère rotation à gauche.More specifically, the bearing edges of said local reliefs of the annular groove of the container and of the interior of the stopper are preferably respectively perpendicular to their surfaces. These are then small abrupt lateral edges of these respective local reliefs of the throat of the container and of the internal surface of the stopper, the contacting of which causes a downward reaction which lowers the stopper. The local reliefs of each surface are spaced around the longitudinal axis of the neck and of the stopper, their respective bearing edges being at the same level relative to this axis so as to simultaneously fulfill their role of driving down the capping. The practical rule for the number of local reliefs of the neck is actually addressed to the number of its support edges acting in a depression of the stopper: thus three local reliefs each having a support edge on the left and a support edge at right may, if the local reliefs of the interior of the stopper have corresponding bearing edges, allow a depression of the stopper according to the invention either by slight rotation to the right, or by slight rotation to the left.

Les bords d'appui des reliefs locaux du goulot, de préférence régulièrement espacés comme déjà indiqué et qu'ils soient à gauche ou à droite, ont une inclinaison comprise de préférence entre 30 et 60° et de préférence encore entre 42 et 48° par rapport à l'axe du goulot, les reliefs d'appui du bouchage ayant des bords coopérant avec lesdits bords d'appui du goulot et de même inclinaison que ces bords d'appui, lesdits reliefs locaux du bouchage étant également espacés et étant en nombre égal ou sous-multiple du nombre desdits reliefs locaux du goulot, donc "égal" dans le cas où le nombre de ces reliefs du goulot est un impair premier.The bearing edges of the local reliefs of the neck, preferably regularly spaced as already indicated and whether they are on the left or on the right, have an inclination preferably between 30 and 60 ° and more preferably between 42 and 48 ° by relative to the axis of the neck, the support reliefs of the closure having edges cooperating with said support edges of the neck and of the same inclination as these support edges, said local reliefs of the closure also being spaced and being in number equal or submultiple of the number of said local reliefs of the neck, therefore "equal" in the case where the number of these reliefs of the neck is a prime odd.

Pour la facilité et l'efficacité des encliquetages successifs, il est préféré que le jonc d'arrêt ait un diamètre extérieur 0,2 à 0,6 mm plus fort que le diamètre extérieur du premier moyen d'encliquetage, et que les reliefs locaux portés par ladite gorge soient en retrait de 0,2 à 0,5 mm au rayon par rapport au jonc d'arrêt et en retrait de 0,1 à 0,3 mm par rapport audit premier moyen d'encliquetage. Le jonc d'arrêt peut être continu ou présenter des discontinuités empêchant une remontée des reliefs intérieurs du bouchage par glissement.For the ease and efficiency of successive snap-ins, it is preferred that the stop ring has an outside diameter 0.2 to 0.6 mm larger than the outside diameter of the first latching means, and that the local reliefs carried by said groove are set back from 0.2 to 0 , 5 mm to the radius with respect to the stop ring and set back 0.1 to 0.3 mm with respect to said first latching means. The stop ring can be continuous or have discontinuities preventing a rise in the internal reliefs of the plugging by sliding.

En pratique, la portion du bouchage comportant ses dits reliefs locaux, qui coopèrent avec des reliefs locaux de la gorge du goulot pour produire la descente du bouchage, est une couronne annulaire d'épaisseur 0,6 à 1 mm en matière plastique, de façon à être suffisamment déformable pour faciliter les deux encliquetages de ses reliefs locaux.In practice, the portion of the stopper comprising its so-called local reliefs, which cooperate with local reliefs in the throat of the neck to produce the descent of the stopper, is an annular crown 0.6 to 1 mm thick in plastic material, so to be sufficiently deformable to facilitate the two snaps of its local reliefs.

Selon une modalité particulièrement avantageuse, le jonc d'arrêt est discontinu et comporte des couples de secteurs ou portions permettant le passage vers le bas entre ces secteurs des reliefs locaux du bouchage, ce passage se faisant avec un forcement local sur l'un de ces secteurs, la descente du bouchage étant ainsi fortement facilitée (couple d'enfoncement divisé par 2 à 3). Une disposition qui permet un tel résultat et interdit en outre toute remontée des reliefs locaux de l'intérieur du bouchage est la suivante : les secteurs de chaque couple du jonc d'arrêt présentent respectivement en vis à vis un bord sensiblement parallèle au bord d'appui latéral qui le surmonte et une extrémité amincie par un bord oblique, typiquement lui aussi sensiblement parallèle audit bord d'appui latéral, la distance entre les extrémités inférieures de ces bords des deux secteurs étant plus faible que la largeur hors-tout minimale d'un dit relief correspondant du bouchage. Le forcement local de ce relief pour descendre à travers l'intervalle insuffisant entre ces deux secteurs s'opère par déformation élastique vers le bas de la partie en relief de ladite extrémité amincie et par chevauchement local de cette mince partie déformée. Même un peu ébréchée, cette extrémité amincie revient en place et empêche complètement, avec les autres secteurs agissant de même vis à vis des autres reliefs locaux du bouchage, toute remontée du bouchage au-dessus du jonc d'arrêt. Ce processus est amélioré lorsque la matière plastique de la capsule est plus dure que celle du goulot, condition connue dans le cas où le bouchage emboîte l'opercule au moyen d'ailettes entaillantes (voir plus loin).According to a particularly advantageous modality, the stop ring is discontinuous and comprises pairs of sectors or portions allowing the passage down between these sectors of the local reliefs of the blockage, this passage being made with a local forcing on one of these sectors, the descent of the blockage is thus greatly facilitated (driving torque divided by 2 to 3). A provision which allows such a result and further prohibits any rise in local reliefs of the interior of the blockage is as follows: the sectors of each pair of the stop ring respectively have opposite an edge substantially parallel to the edge of lateral support which surmounts it and one end thinned by an oblique edge, typically also substantially parallel to said lateral support edge, the distance between the lower ends of these edges of the two sectors being less than the minimum overall width of a said relief corresponding to the blockage. The local forcing of this relief to descend through the insufficient gap between these two sectors takes place by elastic deformation downwards of the raised part of said thinned end and by local overlap of this thin deformed part. Even a little chipped, this thinned end returns in place and completely prevents, with the other sectors acting in the same way with respect to other local reliefs of the blockage, any rise in the blockage above the stop ring. This process is improved when the plastic material of the capsule is harder than that of the neck, a condition known in the case where the capping fits the lid by means of notching fins (see below).

Pour assurer encore mieux le guidage du bouchage et empêcher des tentatives frauduleuses d'enlèvement de ce bouchage par le dessous, il est bon dans le cas où le goulot du récipient se prolonge par une épaule de munir cette épaule d'une couronne annulaire discontinue (guidage seul) ou continue (sécurité anti-fraude), cette couronne s'emboîtant à l'intérieur du bouchage dès son premier encliquetage avec un jeu faible, inférieur à 1 mm au diamètre.To ensure even better the guiding of the stopper and to prevent fraudulent attempts to remove this stopper from below, it is good in the case where the neck of the container is extended by a shoulder to provide this shoulder with a discontinuous annular crown ( guide only) or continuous (anti-fraud security), this ring fitting inside the stopper from its first click with a small clearance, less than 1 mm in diameter.

Toutes les dispositions qui précèdent s'appliquent en particulier au cas dans lequel le bouchage est une capsule à ouverture munie d'une base ou souche, cette souche comportant lesdits moyens d'encliquetage qui sont des reliefs coopérant avec les reliefs de la gorge du goulot, ce goulot étant surmonté d'un opercule d'inviolabilité, la partie ouvrante de la capsule comportant des moyens agissant sur ledit opercule pour sa découpe ou rupture et son enfoncement dans le goulot lors de la translation vers le bas et de l'encliquetage de ladite souche sous ledit jonc d'arrêt.All of the foregoing provisions apply in particular to the case in which the closure is an opening capsule provided with a base or strain, this strain comprising said latching means which are reliefs cooperating with the reliefs of the throat of the neck , this neck being surmounted by a tamper-evident seal, the opening part of the capsule comprising means acting on said seal for its cutting or breaking and its insertion into the neck during the downward translation and the latching of said strain under said stop ring.

Lorsque cette capsule à ouverture ainsi que le goulot et son opercule sont en matière plastique, lesdits moyens agissant sur l'opercule emboîtent de préférence à force l'opercule, de façon que l'opercule reste fixé dans la capsule lors de son ouverture et du versement du produit contenu. Ces moyens d'emboîtage à force de l'opercule sont alors typiquement soit des ailettes longitudinales intérieures à la capsule s'insérant entre des reliefs longitudinaux de l'opercule, soit encore des ailettes radiales longitudinales d'entaillage de l'opercule, comme connu par les deux documents cités au début de la présente description. La matière plastique de la capsule est plus dure que celle de l'opercule pour permettre l'entaillage, et de préférence aussi dans le cas de l'imbrication ailettes/reliefs pour l'obtention d'un serrage permanent.When this opening capsule as well as the neck and its cover are made of plastic, said means acting on the cover preferably force fit the cover, so that the cover remains fixed in the capsule during its opening and payment of the product contained. These means for force-fitting the cover are then typically either longitudinal fins inside the capsule fitting between longitudinal reliefs of the cover, or else longitudinal radial fins for notching the cover, as known by the two documents cited at the beginning of this description. The plastic material of the capsule is harder than that of the cover to allow the notching, and preferably also in the case of nesting fins / reliefs to obtain a permanent tightening.

Dans le cas d'un emboîtage de l'opercule par des ailettes d'entaillage, il est souhaitable que le premier encliquetage de la souche de la capsule intervienne après le début de l'entaillage à pleine section de l'opercule, de façon à réduire l'effort maximal d'enfoncement.In the case of a casing of the cover by notching fins, it is desirable that the first snap-fastening of the strain of the capsule occurs after the start of the notching at full section of the cover, so as to reduce the maximum driving force.

Dans ce même cas, il est avantageux, pour faciliter l'enfoncement de la capsule et réduire encore l'effort correspondant, que l'opercule porte des reliefs longitudinaux 2 à 4 fois plus nombreux que les ailettes d'entaillage de l'opercule et en-dessous de ces reliefs longitudinaux une portion à entailler lisse de hauteur plus faible que celle desdits reliefs. Le début de l'insertion des ailettes se fait facilement et sans indexation, striant au hasard les reliefs longitudinaux étroits de l'opercule, puis l'entaillage traversant la portion lisse qui solidarise l'opercule et la capsule est de durée et d'effort relativement faibles. En dessous de cette portion lisse, l'opercule comporte une portion en retrait précédant une coupelle annulaire qui sert de butée pour le rebouchage du goulot par ledit opercule déchiré et retenu alors dans la partie ouvrante de la capsule.In this same case, it is advantageous, in order to facilitate the insertion of the capsule and to further reduce the corresponding effort, for the cover to have longitudinal reliefs 2 to 4 times more numerous than the notching fins of the cover and below these longitudinal reliefs a smooth notching portion of lower height than that of said reliefs. The beginning of the insertion of the fins is done easily and without indexing, randomly striating the narrow longitudinal reliefs of the cover, then the notching crossing the smooth portion which secures the cover and the capsule is of duration and effort relatively weak. Below this smooth portion, the cover comprises a recessed portion preceding an annular cup which serves as a stop for the filling of the neck with said torn cover and then retained in the opening part of the capsule.

Dans tous les cas d'emboîtage de l'opercule par la capsule, la position juste encliquetée (premier encliquetage) est de préférence la position de livraison, l'étanchéité par l'opercule étant conservée par sa non rupture.In all cases of fitting of the cover by the capsule, the position just snapped on (first click) is preferably the delivery position, the seal by the cover being preserved by not breaking it.

Pour l'ouverture, il faut faire tourner la capsule d'un angle variable mais toujours inférieur à 120°, dans un sens repéré ou dans un sens quelconque, et lorsque la capsule s'enfonce par le mécanisme déjà décrit l'opercule est déchiré par cisaillement et il s'enfonce dans le goulot. Si la rotation déclenchant l'enfoncement est trop faible pour déchirer complètement l'opercule, la faible rotation qui accompagne la descente de la capsule par coopération des reliefs locaux de l'invention et cette descente elle-même entraîne le déchirement complet et l'enfoncement de cet opercule.For the opening, the capsule must be rotated by a variable angle but always less than 120 °, in a marked direction or in any direction, and when the capsule is pushed in by the mechanism already described the cover is torn by shearing and it sinks into the neck. If the rotation triggering the insertion is too low to completely tear the cover, the low rotation which accompanies the descent of the capsule by cooperation of the local reliefs of the invention and this descent itself leads to complete tearing and depression of this seal.

Lorsque le goulot et son opercule sont en aluminium ou alliage d'aluminium, les moyens de la capsule agissant sur cet opercule sont des moyens de défoncement progressif de rabattement de cet opercule à l'intérieur du goulot. La capsule est alors de préférence en matière plus dure que cet opercule, par exemple en matière plastique appropriée. Sa partie ouvrante peut être ouverte dans l'état de livraison sans qu'il y ait rupture de l'opercule.When the neck and its cover are made of aluminum or aluminum alloy, the means of the capsule acting on this cover are means of progressive knockdown of folding of this cover inside the neck. The capsule is then preferably made of a harder material than this cover, for example of suitable plastic. Its opening part can be opened in the delivery condition without breaking the cover.

AVANTAGES DE L'INVENTIONADVANTAGES OF THE INVENTION

  • La fixation de livraison est inviolable et de sécurité accrue. Elle est obtenue essentiellement par un premier encliquetage, puis par une rotation d'angle inférieur à 120° entraînant le deuxième encliquetage plus sûr. Ces modalités sont simples aussi bien pour le fabricant que pour l'utilisateur.The delivery fastener is inviolable and of increased security. It is obtained essentially by a first snap-fastening, then by a rotation of angle less than 120 ° resulting in the second safer snap-fastening. These procedures are simple for both the manufacturer and the user.
  • Dans le cas des capsules à ouverture sur goulot operculé, l'enfoncement final opéré par ladite rotation produit en même temps la rupture de l'opercule et sa rétention, l'ouverture de la capsule étant alors libérée et permettant aussitôt d'utiliser le produit contenu.In the case of capsules with opening on a sealed neck, the final depression effected by said rotation produces at the same time the rupture of the seal and its retention, the opening of the capsule being then released and allowing the product to be used immediately. content.
  • Elle procure des moyens anti-effraction accompagnant l'enfoncement, ce qui est très simple pour l'utilisation.It provides anti-intrusion means accompanying the penetration, which is very simple for use.

1. Description du premier ensemble 1. Description of the first set

Sur la figure 1, on voit un tube 1 avec goulot 2 en PEHD (polyéthylène haute densité) surmonté d'une capsule à ouverture 3 en PP (polypropylène) comprenant une souche ou base 4 et une partie ouvrante ou couvercle 5 pouvant pivoter par une charnière en 6 par rapport à cette base 4. Le goulot 2 dont l'orifice d'extrémité 7 a un diamètre de 7,5 mm est surmonté d'un opercule étanche 8 relié à l'intérieur du goulot par une portion étroite déchirable 9 d'épaisseur 0,2 mm. Au-dessus de cette liaison 9, l'opercule comprend successivement une jupe annulaire bombée extérieurement 10 de diamètre extérieur d'étanchéité plus fort de 0,2 mm que le diamètre de l'orifice 7, puis une coupelle annulaire 11 de diamètre extérieur 10,5 mm servant de butée pour le futur enfoncement de l'opercule 8 dans l'orifice 7, et servant aussi de butée de sécurité pour la montée de l'opercule dans le couvercle 5, puis enfin une portion cylindrique 12 de hauteur 5 mm et de diamètre hors-tout 8,8 mm comportant sur son pourtour des reliefs longitudinaux 24.In Figure 1, we see a tube 1 with neck 2 in HDPE (high density polyethylene) surmounted by an opening capsule 3 in PP (polypropylene) comprising a stump or base 4 and an opening part or cover 5 which can pivot by a hinge at 6 with respect to this base 4. The neck 2 whose end orifice 7 has a diameter of 7.5 mm is surmounted by a tight seal 8 connected to the inside of the neck by a narrow tearable portion 9 0.2 mm thick. Above this connection 9, the cover successively comprises an externally curved annular skirt 10 with an outer sealing diameter greater than 0.2 mm than the diameter of the orifice 7, then an annular cup 11 with an outer diameter 10 , 5 mm serving as a stop for the future insertion of the cover 8 into the orifice 7, and also serving as a safety stop for mounting the cover in the cover 5, then finally a cylindrical portion 12 of height 5 mm and with an overall diameter of 8.8 mm, having longitudinal reliefs 24 around its periphery.

Le goulot 2 porte 4 mm en dessous de son orifice 7, à l'extrémité inférieure d'une surface extérieure inclinée 14 de diamètre croissant, un relief d'encliquetage 15 en forme de nervure 15 de diamètre extérieur 14 mm et de dessous annulaire horizontal 16 surmontant une portion cylindrique en retrait 17 de diamètre 12 mm et de hauteur 2,5 mm. A cette portion en retrait 17 succède un jonc d'arrêt. 18 de diamètre 14,4 mm plus fort que celui du relief d'encliquetage 15. Les reliefs annulaires 15 et 18 et la portion en retrait 17 délimitent une gorge annulaire 19 de profondeur 1 mm (figures 1 et 2). A l'intérieur de cette gorge 19, il y a trois reliefs locaux 20 espacés de 120° en relief de 0,8 mm par rapport au fond 17 de la gorge 19, chacun de ces reliefs locaux 20 étant de contour trapézoïdal de hauteur 2,3 mm avec deux côtés latéraux 21 et 22 inclinés à 45° par rapport à la direction de l'axe longitudinal 23, ces côtés 21 et 22 correspondant à des bords francs regardant respectivement à droite et à gauche (figures 1 à 3).The neck 2 carries 4 mm below its orifice 7, at the lower end of an inclined outer surface 14 of increasing diameter, a latching relief 15 in the form of a rib 15 with an outer diameter of 14 mm and a horizontal annular underside 16 surmounting a recessed cylindrical portion 17 with a diameter of 12 mm and a height of 2.5 mm. This recessed portion 17 is followed by a stop ring. 18 with a diameter of 14.4 mm greater than that of the snap-fit relief 15. The annular reliefs 15 and 18 and the recessed portion 17 delimit an annular groove 19 with a depth of 1 mm (Figures 1 and 2). Inside this groove 19, there are three local reliefs 20 spaced 120 ° in relief of 0.8 mm relative to the bottom 17 of the groove 19, each of these local reliefs 20 being of trapezoidal contour of height 2 , 3 mm with two lateral sides 21 and 22 inclined at 45 ° relative to the direction of the longitudinal axis 23, these sides 21 and 22 corresponding to sharp edges looking respectively to the right and to the left (Figures 1 to 3).

En-dessous du jonc d'arrêt 18, il y a une autre gorge annulaire 25 de hauteur 2,7 mm destinée à l'encliquetage des reliefs locaux intérieurs 13 de la souche 4 de la capsule 3 en fin d'enfoncement (reliefs locaux 13 décrits plus loin).Below the stop ring 18, there is another annular groove 25 of height 2.7 mm intended for the latching of the local internal reliefs 13 of the stump 4 of the capsule 3 at the end of insertion (local reliefs 13 described below).

La partie ouvrante ou couvercle 5 de la capsule 3 comporte une tubulure centrale 26 ouverte à ses deux extrémités, sa surface intérieure 27 de diamètre 8,9 mm portant des ailettes radiales 28 s'emboîtant avec forcement entre les reliefs longitudinaux 24 de l'opercule 8. Elle comporte aussi une tubulure intermédiaire 29 s'encliquetant avec un effort faible dans la souche ou base 4.The opening part or cover 5 of the capsule 3 comprises a central tube 26 open at its two ends, its inner surface 27 of diameter 8.9 mm carrying radial fins 28 interlocking with forcing between the longitudinal reliefs 24 of the cover 8. It also includes an intermediate tube 29 which snaps into place with little effort in the stump or base 4.

Cette souche ou base 4 comprend une portion cylindrique centrale 31 portant intérieurement les trois reliefs locaux à encliqueter 13 d'épaisseur 0,8 mm, de hauteur 2,3 mm et de diamètre intérieur enveloppe au repos 13 mm, chacun de ces reliefs locaux 13 étant d'allure trapézoïdale inversée par rapport aux reliefs trapézoïdaux 20 de la gorge 19, avec des bords latéraux 32 et 33 inclinés à 45° par rapport à l'axe 23, et pouvant être opposés respectivement à des bords tels que 22 et 21. La portion basse 34 de la portion centrale 31 améliore le centrage des opérations d'enfoncement de la capsule 3, elle est déformable transversalement pour faciliter le franchissement des reliefs annulaires d'encliquetage 15 et 18 par les reliefs locaux 13 qu'elle porte. Son épaisseur est ici de 0,7 mm, et dans le cas général de 0,6 à 1 mm. La souche 4 comprend encore une portion intermédiaire oblique 35 comportant une zone 36 d'encliquetage de la tubulure 29 de la partie ouvrante 5 et une jupe extérieure rigide 39 emboîtant avec un jeu de 0,5 mm au diamètre une couronne annulaire 37 portée par l'épaule 38 du récipient, cela dès le premier encliquetage (franchissement du relief 15).This strain or base 4 comprises a central cylindrical portion 31 internally carrying the three local snap-on reliefs 13 of thickness 0.8 mm, height 2.3 mm and inside diameter of the envelope at rest 13 mm, each of these local reliefs 13 being of reverse trapezoidal shape with respect to the trapezoidal reliefs 20 of the groove 19, with lateral edges 32 and 33 inclined at 45 ° with respect to the axis 23, and being able to be opposed respectively to edges such as 22 and 21. The lower portion 34 of the central portion 31 improves the centering of the insertion operations of the capsule 3, it is deformable transversely to facilitate the crossing of the annular snap reliefs 15 and 18 by the local reliefs 13 that it carries. Its thickness here is 0.7 mm, and in the general case from 0.6 to 1 mm. The strain 4 also comprises an oblique intermediate portion 35 comprising a zone 36 for latching the tubing 29 of the opening part 5 and a rigid outer skirt 39 fitting with a clearance of 0.5 mm in diameter an annular crown 37 carried by the 'shoulder 38 of the container, this from the first click (crossing of the relief 15).

2. Enfoncement de la capsule du premier ensemble 2. Insertion of the capsule of the first set

Le premier encliquetage des trois reliefs locaux 13 de la souche 4 dans la gorge 19 est obtenu facilement, grâce à l'entrée conique 14 du goulot 2 et à la déformabilité de la couronne annulaire 34 (Fig.3) portant ces reliefs 13. La figure 3 permet de distinguer les points importants pour l'enfoncement, les portions concernées du goulot 2 et de la souche 4 étant représentées écartées pour plus de clarté. Simultanément, les reliefs 24 et les ailettes 28 de l'opercule 8 et de la partie ouvrante 5 de la capsule 3 ont commencé à s'interpénétrer, l'opercule 8 étant immobilisé en rotation par rapport à cette capsule 3. La jupe extérieure 39 emboîte déjà la couronne annulaire 37 de l'épaule 38 du récipient, empêchant un éventuel basculement de la capsule 3 lors des opérations de livraison.The first snap-fastening of the three local reliefs 13 of the strain 4 in the groove 19 is easily obtained, thanks to the conical entry 14 of the neck 2 and to the deformability of the annular crown 34 (FIG. 3) carrying these reliefs 13. The FIG. 3 makes it possible to distinguish the important points for the penetration, the portions concerned of the neck 2 and of the strain 4 being shown apart for greater clarity. Simultaneously, the reliefs 24 and the fins 28 of the cover 8 and of the opening part 5 of the capsule 3 have started to interpenetrate, the cover 8 being immobilized in rotation relative to this capsule 3. The outer skirt 39 already fits the annular crown 37 of the shoulder 38 of the container, preventing a possible tilting of the capsule 3 during the delivery operations.

Pour ouvrir ensuite, on fait tourner la capsule sur elle-même dans un sens ou l'autre et rapidement il se produit un enfoncement et un encliquetage en-dessous du jonc d'arrêt 18 par le mécanisme déjà décrit. Comme on le voit sur la figure 4 :

  • les reliefs locaux 13 de la couronne 34 de la souche 4 sont encliquetés dans la gorge 25 avec un jeu assez faible (0,4 mm sur la hauteur) de façon à assurer une immobilisation verticale satisfaisante de la souche 4;
  • l'opercule 8 a été déchiré par la rotation de la capsule 3, et sa jupe annulaire 10 a été enfoncée dans l'orifice 7 du goulot 2, permettant un stockage et des rebouchages étanches;
  • la jupe extérieure 39 est enfoncée autour de la couronne annulaire 37, empêchant encore mieux les basculements ou soulèvements de la souche 4;
  • la capsule 3 peut toujours tourner autour du goulot 2, ce qui est pratique, et l'ouverture de la partie ouvrante 5 entraîne l'opercule 8 maintenant emboîté à force dans cette partie 5. L'utilisateur peut positionner la capsule et sa charnière où il le souhaite pour une utilisation facile.
To then open, the capsule is rotated on itself in one direction or the other and quickly there is a depression and a snap-fastening below the stop ring 18 by the mechanism already described. As seen in Figure 4:
  • the local reliefs 13 of the crown 34 of the strain 4 are snapped into the groove 25 with a fairly small clearance (0.4 mm in height) so as to ensure satisfactory vertical immobilization of the strain 4;
  • the cover 8 has been torn by the rotation of the capsule 3, and its annular skirt 10 has been inserted into the orifice 7 of the neck 2, allowing storage and tight plugs;
  • the outer skirt 39 is pressed around the annular crown 37, preventing even better the tilting or lifting of the strain 4;
  • the capsule 3 can always rotate around the neck 2, which is practical, and the opening of the opening part 5 causes the cover 8 now forcibly fitted into this part 5. The user can position the capsule and its hinge where he wants it for easy use.

3. Deuxième ensemble (figure 5) 3. Second set (Figure 5)

Le récipient est un tube 40 en aluminium à 99.5 % de pureté comportant les caractéristiques de l'invention, les reliefs locaux étant obtenus par des opérations de façonnage traditionnelles. L'opercule 41 a son pourtour 42 aminci pour faciliter la découpe. L'enfoncement de la capsule en matière plastique dure entre l'encliquetage initial des reliefs locaux 13 en-dessous du relief 15 et l'encliquetage final de ces reliefs 13 en-dessous du relief annulaire d'arrêt 18 et dans la gorge 25 s'accompagne d'un défonçage de l'opercule 41 et d'un rabattement d'une partie au moins de cet opercule 41 à l'intérieur du goulot 2. Pour cela, la partie ouvrante 5 de la capsule comporte un bord incliné en arête 42 et un bord d'appui 43 opérant le rabattement de la partie découpée. Les reliefs locaux du goulot sont espacés également comme les reliefs locaux 13 de la capsule.The container is a tube 40 made of 99.5% purity aluminum comprising the characteristics of the invention, the local reliefs being obtained by traditional shaping operations. The cover 41 has its circumference 42 thinned to facilitate cutting. The insertion of the hard plastic capsule between the initial locking of the local reliefs 13 below the relief 15 and the final latching of these reliefs 13 below the annular stop relief 18 and in the groove 25 is accompanied by a knockout of the cover 41 and a drawdown of a at least part of this cover 41 inside the neck 2. For this, the opening part 5 of the capsule has an edge inclined at an edge 42 and a bearing edge 43 operating the folding down of the cut part. The local reliefs of the neck are also spaced like the local reliefs 13 of the capsule.

4. Troisième ensemble (figures 6 à 8) 4. Third set (Figures 6 to 8)

Le troisième ensemble comprend comme le premier un tube 45 en PEHD et une capsule à ouverture en PP dont seul un relief local 13 s'encliquetant successivement dans les gorges annulaires 19 et 25 apparaît sur les figures 6 et 7.
Comme on le voit sur la figure 6, qui est une vue extérieure déroulée de la gorge annulaire 19 et du jonc d'arrêt interrompu 180 qui délimite cette gorge, ledit relief local 13 de l'intérieur de la souche ou base de la capsule y étant représenté après son encliquetage dans la gorge 19 pour les besoins de l'explication, le jonc d'arrêt 180 comprend des secteurs espacés 181, 182 et 183.
Le couple de secteurs 181 et 182 présente en vis-à-vis un bord 220 parallèle au bord 22 du relief local 20 du tube 45 et une extrémité 184 amincie en pointe par un bord oblique 185 sensiblement parallèle à ce même bord 22. L'épaisseur ou hauteur du jonc interrompu 180 selon l'axe du tube est de 0,7 mm et sa largeur radiale est, comme pour le tube 1, de 1,2 mm. La distance "d" entre l'extrémité inférieure 221 du bord 220 et l'extrémité inférieure 186 du bord oblique 185 est de 2 mm, elle est inférieure à la largeur hors tout minimale "l" du relief local 13, qui est ici la longueur de son bord supérieur 130. Ce relief 13 ne pourra donc pas franchir en sens inverse les secteurs 181 et 182 du jonc d'arrêt 180 une fois son encliquetage dans la gorge inférieure 25 opéré (fig. 7). Ce principe permet aussi bien d'obtenir un engagement partiel en remontée des reliefs locaux 13 de la capsule sans qu'il soit possible de franchir les secteurs du jonc d'arrêt.The third assembly includes, like the first, a HDPE tube 45 and an opening capsule in PP of which only a local relief 13 snapping successively into the annular grooves 19 and 25 appears in FIGS. 6 and 7.
As can be seen in FIG. 6, which is an unrolled external view of the annular groove 19 and of the interrupted stop ring 180 which delimits this groove, said local relief 13 from the inside of the stump or base of the capsule y being shown after it clicks into the groove 19 for the purposes of the explanation, the retaining ring 180 comprises spaced sectors 181, 182 and 183.
The pair of sectors 181 and 182 has vis-à-vis an edge 220 parallel to the edge 22 of the local relief 20 of the tube 45 and an end 184 thinned in point by an oblique edge 185 substantially parallel to this same edge 22. The thickness or height of the interrupted rod 180 along the axis of the tube is 0.7 mm and its radial width is, as for tube 1, 1.2 mm. The distance "d" between the lower end 221 of the edge 220 and the lower end 186 of the oblique edge 185 is 2 mm, it is less than the minimum overall width "l" of the local relief 13, which is here the length of its upper edge 130. This relief 13 cannot therefore cross sectors 181 and 182 of the stop ring 180 in the opposite direction once it has snapped into the lower groove 25 (fig. 7). This principle also makes it possible to obtain a partial engagement in raising the local reliefs 13 of the capsule without it being possible to cross the sectors of the stop ring.

Sur la figure 7, on a représenté la déformation élastique d'une portion 187 du secteur 182 incluant son extrémité amincie 184, cette portion 187 étant couchée et chevauchée par une partie du relief local 13 plus dur. Ce relief 13 ayant franchi le jonc d'arrêt en glissant le long du bord 220 et sur la portion 187, cette portion 187 se redresse comme l'indique la flèche 188 et elle empêchera avec les autres secteurs toute remontée du bouchage.In Figure 7, there is shown the elastic deformation of a portion 187 of sector 182 including its thinned end 184, this portion 187 being lying and overlapped by a portion of the local relief 13 harder. This relief 13 having crossed the stop ring by sliding along the edge 220 and on the portion 187, this portion 187 straightens up as indicated by the arrow 188 and it will prevent with the other sectors any rise in the blockage.

Plusieurs mesures de couple d'enfoncement ont été faites pour comparer cette disposition avec jonc d'arrêt discontinu 180 et celle du tube avec jonc d'arrêt continu 18. Le couple d'ouverture et d'enfoncement est divisé par 2 à 2,3 avec la disposition discontinue.Several driving torque measurements were made to compare this arrangement with discontinuous stop ring 180 and that of the tube with continuous stop ring 18. The opening and driving torque is divided by 2 to 2.3 with the discontinuous layout.

Sur la figure 8, on voit que l'opercule 8 en PE-HD porte latéralement 36 petits reliefs ou dents 80 longitudinales de hauteur 1,8 mm, faciles à entailler par les 12 ailettes longitudinales d'entaillage 240 portées par la tubulure centrale 26 de la partie ouvrante 5 de la capsule 3. En dessous des reliefs 80, il y a une portion lisse 81 de hauteur 1,2 mm et de même diamètre hors-tout 8 mm que les reliefs longitudinaux 80. Les ailettes 240 sont en train d'entailler facilement les reliefs 80 ou parfois de s'y insérer, ce qui produit une fixation anti rotation de la capsule 3 sur l'opercule 8 et un centrage de l'enfoncement. Ensuite elles entailleront en un temps réduit la portion pleine et lisse 81, ce qui procure une fixation anti-arrachement de l'opercule 8 dans la partie ouvrante 5 et leur arrêt en position de livraison de l'ensemble est facilité par le débouché de ces ailettes 240 dans une portion en retrait 82 précédant la coupelle annulaire 11 dont on a déjà vu le rôle à propos du tube 1 (premier ensemble);In FIG. 8, it can be seen that the cover 8 in PE-HD carries 36 small reliefs or longitudinal teeth 80, 1.8 mm high, laterally, easy to cut by the 12 longitudinal notching fins 240 carried by the central tube 26 of the opening part 5 of the capsule 3. Below the reliefs 80, there is a smooth portion 81 of height 1.2 mm and of the same overall diameter 8 mm as the longitudinal reliefs 80. The fins 240 are in the process to easily score the reliefs 80 or sometimes to insert therein, which produces an anti-rotation fixing of the capsule 3 on the cover 8 and a centering of the depression. Then they will cut in a short time the full and smooth portion 81, which provides an anti-tearing attachment of the cover 8 in the opening part 5 and their stopping in the delivery position of the assembly is facilitated by the outlet of these fins 240 in a recessed portion 82 preceding the annular cup 11, the role of which has already been seen in connection with the tube 1 (first assembly);

L'ensemble des moyens 80,81 et 82 situés au-dessus de la coupelle 11 donne un début d'enfoncement de la capsule beaucoup plus facile.The set of means 80, 81 and 82 located above the cup 11 gives a much easier start to depress the capsule.

En ajoutant à cette disposition la structure discontinue du jonc d'arrêt 180 décrite pour ce troisième ensemble, on obtient une grande facilité de l'enfoncement total de la capsule allant jusqu'à l'ouverture du tube par encliquetage complet de la capsule, provoquant la rupture de la TE ("Tamper Evidence") et le bouchage étanche du tube par son opercule. Le couple d'ouverture du tube du 3° ensemble, ne différant de celui du 1er ensemble que par les particularités ici décrites, est divisé par 2,5 à 3 et est typiquement de 0,4 à 0,5 N.m.By adding to this arrangement the discontinuous structure of the stop ring 180 described for this third assembly, one obtains a great facility of the total insertion of the capsule going until the opening of the tube by complete snap-fastening of the capsule, causing rupture of the TE ("Tamper Evidence") and tight sealing of the tube by its seal. The opening torque of the tube of the 3rd assembly, not differing from that of the 1st together only by the features described here, is divided by 2.5 to 3 and is typically from 0.4 to 0.5 Nm
