Description

Domaine de l'inventionField of the invention

La présente invention concerne un conteneur tubulaire, fermé à sa partie supérieure par un moyen d'obturation de type bouchon refermable y compris à charnière, muni d'un dispositif de compensation.The present invention relates to a tubular container, closed at its upper part by closure means of the closable cap type including hinge, provided with a compensation device.

L'invention concerne plus particulièrement un conteneur de ce type destiné notamment à conditionner des produits à usage pharmaceutique, cosmétique, alimentaire, vétérinaire, de diagnostique ou encore phytosanitaire, pouvant se présenter sous diverses formes telles que par exemples, des pastilles, des comprimés, des cachets, des tablettes. Ces produits conditionnés peuvent être empilés axialement à l'intérieur du conteneur tubulaire, les dimensions internes de ce dernier correspondant sensiblement aux dimensions externes des produits conditionnés ou bien être en vrac à l'intérieur dudit conteneur.The invention relates more particularly to a container of this type intended in particular to package products for pharmaceutical, cosmetic, food, veterinary, diagnostic or phytosanitary purposes, which may be in various forms such as, for example, pellets, tablets, tablets, tablets. These packaged products can be stacked axially inside the tubular container, the internal dimensions of the latter corresponding substantially to the external dimensions of the packaged products or be loose within said container.

Etat de la techniqueState of the art

Les produits conditionnés mentionnés ci-dessus ont souvent une structure poreuse et friable, en particulier lorsqu'il s'agit de comprimés effervescents, ce qui les rend particulièrement fragiles aux chocs et à l'abrasion. Cette détérioration mécanique est souvent occasionnée lors de la manutention et du transport de ces produits conditionnés dans des tubes eux-mêmes stockés dans des caisses ou des cartons, au cours desquels les chocs ou les secousses sont inévitables.The packaged products mentioned above often have a porous and friable structure, especially when it comes to effervescent tablets, which makes them particularly fragile to shocks and abrasion. This mechanical deterioration is often caused during the handling and transportation of these packaged products in tubes themselves stored in crates or boxes. cartons, during which shocks or shocks are inevitable.

Il a déjà été proposé de maintenir en position lesdits produits dans un conteneur tubulaire, plein ou sensiblement plein, grâce à un dispositif de compensation ayant la forme d'un ressort ou d'une vrille. Ainsi, les produits conditionnés ne peuvent plus bouger de manière intempestive à l'intérieur du conteneur lors du transport.It has already been proposed to hold said products in position in a tubular container, solid or substantially full, thanks to a compensation device in the form of a spring or a twist. Thus, the packaged products can not move inadvertently inside the container during transport.

De plus, de tels dispositifs de compensation permettent de compenser les écarts de cote d'épaisseur des produits unitaires conditionnés, ou de conditionner dans un même conteneur des produits d'épaisseurs différentes, à l'origine d'un jeu inéluctable existant entre le fond du moyen d'obturation et la face supérieure de la pile de produits conditionnés dans le conteneur. Toute liberté de déplacement à l'intérieur d'un tel espace est une source possible de détérioration desdits produits conditionnés.In addition, such compensation devices make it possible to compensate for differences in the thickness dimension of the packaged unit products, or to pack in one and the same container products of different thicknesses, at the origin of an unavoidable clearance existing between the bottom shutter means and the upper face of the stack of products packaged in the container. Any freedom of movement within such a space is a possible source of deterioration of said packaged products.

Quatre documents reflétant particulièrement l'état de la technique la plus proche dans ce domaine ont été sélectionnés, et sont décrits ci-après. Ils exposent différentes solutions de maintien des produits conditionnés dans un conteneur tubulaire à l'aide d'un dispositif de compensation.Four documents particularly reflecting the closest state of the art in this field have been selected, and are described below. They expose different solutions for keeping packaged products in a tubular container using a compensation device.

Un premier document ( US 2005/0016873 A1 ) décrit différents modes de réalisation d'un conteneur déshydratant permettant le stockage de comprimés, de type par exemple pharmaceutique. Ce conteneur comprend dans son fond et/ou dans son moyen d'obturation, de type bouchon relié audit conteneur par une charnière, un ressort élastique constitué de brins hélicoïdaux entrecroisés ou non, ledit ressort pouvant être réalisé en matière polymère déshydratante et sur lequel prennent appui les produits conditionnés empilés.A first document ( US 2005/0016873 A1 ) discloses various embodiments of a desiccant container for storing tablets, such as pharmaceutical type. This container comprises in its bottom and / or in its closure means, cap type connected to said container by a hinge, an elastic spring constituted by helical strands intercrossed or not, said spring being made of desiccant polymer material and on which support stacked packaged products.

Ce premier document présente un dispositif de compensation de type ressort élastique, ce dernier étant fixé soit sur le fond du conteneur soit sur la surface interne de son moyen d'obturation par surmoulage, ce qui engendre une certaine cohésion entre matériaux.This first document has a resilient spring type compensation device, the latter being fixed either on the bottom of the container or on the inner surface of its overmolding closure means, which generates a certain cohesion between materials.

Un deuxième document, le document US 1 671 285 , décrit un conteneur distributeur de comprimés, dont le corps est obturé à son extrémité inférieure par un fond rapporté sur lequel est fixé un ressort muni d'un plateau, la pile de comprimés stockés prenant appui sur ledit plateau. Un élément de retenue à l'extrémité supérieure du conteneur permet une extraction unitaire du comprimé situé sur le dessus de la pile par une ouverture latérale aménagée sur la partie supérieure du conteneur.A second document, the document US 1,671,285 , discloses a tablet dispensing container, whose body is closed at its lower end by an attached base on which is fixed a spring provided with a tray, the stack of stored tablets bearing on said tray. A retaining element at the upper end of the container allows a unit extraction of the tablet located on the top of the stack by a lateral opening arranged on the upper part of the container.

Ce document propose ainsi un dispositif de compensation sous la forme d'un ressort qui contribue aussi à l'extraction des comprimés, du fait de la détente dudit ressort et qui permet une extraction latérale du comprimé situé sur le dessus de la pile. Ce dispositif de compensation se compose de deux pièces différentes, à savoir un ressort et un plateau.This document thus proposes a compensation device in the form of a spring which also contributes to the extraction of the tablets, because of the expansion of said spring and which allows a lateral extraction of the tablet located on the top of the stack. This compensation device consists of two different parts, namely a spring and a plate.

Un troisième document, le document EP 1 602 596 A2 , ressemblant beaucoup au document US 1 671 285 , décrit aussi un conteneur distributeur pour comprimés effervescents qui reposent empilés axialement sur un disque perforé associé à un ressort, ce dernier étant apposé sur la face supérieure perforée d'un compartiment aménagé au fond du conteneur, et dans lequel est inséré un agent déshydratant. Le conteneur décrit dans ce document comporte en outre un capuchon à vis muni d'un joint assurant une fermeture hermétique. Enfin, un compartiment de stockage d'un nombre limité de comprimés, muni aussi d'un moyen déshydratant, et obturé par un bouchon à l'une de ses extrémités, peut être vissé par son autre extrémité, à la base inférieure du conteneur.A third document, the document EP 1 602 596 A2 , much like the document US 1,671,285 , also discloses a dispensing container for effervescent tablets which rest stacked axially on a perforated disc associated with a spring, the latter being affixed to the perforated upper face of a compartment arranged at the bottom of the container, and in which is inserted a desiccant. The container described in this document further comprises a screw cap provided with a seal ensuring an airtight seal. Finally, a storage compartment of a limited number of tablets, also provided with a dehydrating means, and closed by a plug at one of its ends, can be screwed by its other end to the lower base of the container.

Ce document présente le même dispositif de compensation que le document US 1 671 285 , c'est-à-dire un dispositif à ressort, permettant l'extraction de comprimés, avec en outre quelques améliorations telles que la présence d'un agent déshydratant et d'un compartiment de stockage additionnel.This document presents the same compensation device as the document US 1,671,285 , that is to say a spring device, allowing the extraction of tablets, with further improvements such as the presence of a desiccant and an additional storage compartment.

Enfin, un quatrième document, le document FR 2 694 270 décrit un tube d'emballage, notamment pour des produits pharmaceutiques tels que des comprimés, fermé par un bouchon, ce tube comportant un panier suspendu destiné à recevoir lesdits comprimés, et grâce auquel ils sont protégés contre les chocs. Des moyens élastiques sont prévus de manière à compenser automatiquement l'espace axial existant entre la face supérieure du comprimé supérieur et la face interne en vis-à-vis du bouchon. Ces mêmes moyens élastiques peuvent aussi être agencés symétriquement dans le fond du panier suspendu. Un déshydratant peut, en outre, être inséré au fond du tube.Finally, a fourth document, the document FR 2,694,270 describes a packaging tube, in particular for pharmaceutical products such as tablets, closed by a stopper, this tube comprising a suspended basket for receiving said tablets, and thanks to which they are protected against shocks. Elastic means are provided so as to automatically compensate for the axial space existing between the upper face of the upper tablet and the inner face vis-à-vis the plug. These same elastic means can also be arranged symmetrically in the bottom of the suspended basket. A desiccant may further be inserted at the bottom of the tube.

Ce document décrit un tube d'emballage équipé d'un dispositif de compensation dont la conception du panier suspendu paraît complexe du point de vue du moulage.This document describes a packaging tube equipped with a compensation device whose design of the suspended basket seems complex from the point of view of molding.

Au vu de l'état de la technique décrit ci-dessus, les dispositifs de compensation sont souvent de conception complexe quant à leur forme. De plus, ils sont généralement réalisés pour s'adapter de manière tout à fait spécifique aux dimensions d'un conteneur donné, ou le cas échéant d'un bouchon donné, dans lequel ils doivent être insérés.
Ainsi, la réalisation d'un dispositif de compensation apparaît dépendre des caractéristiques, en particulier des dimensions, du conteneur ou du bouchon dans lequel il doit être inséré, et engendre des coûts de fabrication élevés du fait qu'un seul dispositif de compensation ne peut être utilisé que pour un seul conteneur donné; ces coûts venant s'ajouter à ceux de l'élaboration de formes complexes du dispositif de compensation.In view of the state of the art described above, the compensation devices are often of complex design as to their shape. In addition, they are generally made to adapt in a very specific manner to the dimensions of a given container, or if necessary a given plug, in which they must be inserted.
Thus, the production of a compensation device appears to depend on the characteristics, in particular on the dimensions, of the container or plug in which it is to be inserted, and generates high manufacturing costs because only one compensation device can be used for only one given container; these costs are added to those of the development of complex forms of the compensation device.

Objets de l'inventionObjects of the invention

Il y a donc un problème technique posé et non résolu, qui est celui de ne pouvoir réaliser un dispositif de compensation de réalisation aisée et pouvant s'adapter à de multiples conteneurs tubulaires de dimensions et de diamètres voisins lorsqu'ils sont de section circulaire, tout en assurant aussi une protection suffisante des produits conditionnés à l'encontre des chocs ou secousses occasionnés lors du transport ou de la manutention.There is therefore a technical problem that has been posed and not solved, which is that of not being able to produce a compensation device that is easy to produce and that can be adapted to multiple tubular containers of similar dimensions and diameters when they are of circular section. while also ensuring sufficient protection of the packaged products against shocks or jolts caused during transport or handling.

Un autre problème posé au concepteur est de proposer un conteneur tubulaire équipé d'un dispositif de compensation sous la forme d'une pièce moulée indépendante dudit conteneur et s'insérant aisément et de manière à ce qu'il devienne solidaire de celui-ci. L'insertion du dispositif de compensation dans le conteneur tubulaire pouvant être réalisée :

  • avant l'introduction des produits conditionnés, ou
  • conjointement avec ces derniers.
    Un autre problème technique souvent mal résolu et à résoudre est celui de conteneurs tubulaires clos par un bouchon de type à charnière dont le mouvement d'ouverture-fermeture est gêné, voire empêché quand ledit bouchon est muni d'un dispositif de compensation, pour ce faire, la hauteur dudit dispositif de compensation doit être réduite, ce qui provoque une perte d'efficacité de l'action de compensation.
Another problem posed to the designer is to propose a tubular container equipped with a compensation device in the form of a molded part independent of said container and easily inserted and so that it becomes integral with it. The insertion of the compensation device into the tubular container can be performed:
  • before the introduction of packaged products, or
  • jointly with them.
    Another technical problem often badly solved and to be solved is that of tubular containers closed by a hinge-type plug whose opening-closing movement is obstructed or even prevented when said plug is provided with a compensation device, for which to do, the height of said compensation device must be reduced, which causes a loss of efficiency of the compensation action.

Dès lors, l'objet principal consiste à réaliser un conteneur tubulaire équipé d'un dispositif de compensation tel que:

  • ce dernier puisse s'adapter à de multiples conteneurs de dimensions et de diamètres voisins lorsque le conteneur est de section circulaire,
  • sa forme, de conception peu complexe, permette une insertion aisée et définitive au fond dudit conteneur, et ce avant l'introduction des produits conditionnés ou conjointement avec ces derniers,
  • sa position au fond dudit conteneur laisse une entière liberté pour le choix du type du moyen d'obturation, y compris à charnière.
Therefore, the main object consists in producing a tubular container equipped with a compensation device such as:
  • the latter can adapt to multiple containers of similar dimensions and diameters when the container is of circular section,
  • its shape, of uncomplicated design, allows an easy and definitive insertion in the bottom of said container, and before the introduction of the packaged products or jointly with them,
  • its position at the bottom of said container leaves complete freedom for the choice of the type of closure means, including hinged.

Sommaire de l'inventionSummary of the invention

Dès lors l'invention concerne un conteneur tubulaire, fermé à sa partie supérieure par un moyen d'obturation de type bouchon y compris à charnière, pour le conditionnement de produits unitaires empilés axialement ou en vrac tels que pastilles, comprimés, cachets, tablettes, et muni d'un dispositif de compensation, positionné au fond dudit conteneur, ledit conteneur comprenant éventuellement un moyen déshydratant, ledit dispositif de compensation étant constitué :

  • d'un moyen de compensation muni à ses extrémités d'une grande base et d'une petite base qui est au plus égale à la grande base, et sur l'une desquelles reposent les produits conditionnés, et
  • d'un moyen de fixation,
qui se caractérise en ce que ledit moyen de fixation :
  • est solidaire du moyen de compensation,
  • et se compose d'éléments mécaniques, à mémoire de forme qui, après leur déformation élastique consécutive à l'insertion dudit dispositif de compensation dans le fond du conteneur, rendent solidaire le dispositif de compensation dudit conteneur en exerçant sur la paroi latérale interne du conteneur une force de friction perpendiculaire à ladite paroi.

  • a compensation means provided at its ends with a large base and a small base which is at most equal to the large base, and on one of which the packed products rest, and
  • a fastening means,
characterized in that said fixing means:
  • is integral with the compensation means,
  • and consists of mechanical elements, shape memory which, after their elastic deformation consecutive to the insertion of said compensation device in the bottom of the container, make integral the compensation device of said container by exerting on the inner side wall of the container a friction force perpendicular to said wall.

Description détaillée de l'inventionDetailed description of the invention

Le conteneur tubulaire selon l'invention est destiné au conditionnement de produits solides, stockés à l'intérieur dudit conteneur sous la forme d'un empilement axial ou en vrac. Le conteneur selon l'invention peut être utilisé pour le conditionnement de produits à usage pharmaceutique, cosmétique, alimentaire, vétérinaire, de diagnostique ou phytosanitaire.The tubular container according to the invention is intended for the packaging of solid products, stored inside said container in the form of an axial stack or in bulk. The container according to the invention can be used for the packaging of products for use pharmaceutical, cosmetic, food, veterinary, diagnostic or phytosanitary.

Lorsque l'empilement des produits conditionnés est axial, les dimensions internes du conteneur tubulaire correspondent sensiblement aux dimensions externes desdits produits conditionnés. L'empilement axial des produits conditionnés est préféré à l'entassement en vrac.When the stack of packaged products is axial, the internal dimensions of the tubular container substantially correspond to the external dimensions of said packaged products. Axial stacking of packaged products is preferred over bulk packing.

Avantageusement, le conteneur tubulaire peut être de section polygonale, elliptique, circulaire, et est préférentiellement de section circulaire.Advantageously, the tubular container may be of polygonal, elliptical, circular section, and is preferably of circular section.

De tels produits unitaires conditionnés tels que des pastilles, des comprimés, peuvent être friables, si bien que leur maintien en position est primordial afin d'éviter tout risque de détérioration par effet mécanique, en particulier de choc ou d'abrasion.Such packaged unit products such as tablets and tablets can be friable, so that their holding in position is essential in order to avoid any risk of deterioration by mechanical effect, in particular shock or abrasion.

Le conteneur tubulaire est fermé à sa partie supérieure par un moyen d'obturation de type bouchon refermable, y compris à charnière, de telle sorte que lorsque ledit conteneur est rempli ou quasi-rempli, le dispositif de compensation dont est muni le conteneur, exerce son action de compensation sur les produits conditionnés et les maintient en position, évitant ainsi tout risque de détérioration.The tubular container is closed at its upper part by a closure means of closable cap type, including hinged, so that when said container is filled or almost filled, the compensation device which is provided with the container, exerts its compensation action on the packaged products and keeps them in position, thus avoiding any risk of deterioration.

Le dispositif de compensationThe compensation device

Le conteneur tubulaire selon l'invention est muni d'un dispositif de compensation, positionné au fond dudit conteneur, et qui est constitué :

  • d'un moyen de compensation,
  • d'un moyen de fixation.
The tubular container according to the invention is provided with a compensation device, positioned at the bottom of said container, and which consists of:
  • a compensation means,
  • a fastening means.

Le moyen de compensation et le moyen de fixation sont rendus solidaires l'un de l'autre.The compensation means and the fixing means are secured to one another.

Le moyen de fixation est rendu solidaire du moyen de compensation par collage, soudage, co-injection ou injection conduisant à un ensemble monobloc. Le moyen de compensation et le moyen de fixation sont coaxiaux.The fixing means is secured to the compensation means by gluing, welding, co-injection or injection leading to a one-piece assembly. The compensation means and the fixing means are coaxial.

Le moyen de compensationThe compensation means

Le moyen de compensation du dispositif de compensation est creux et de forme apparente cylindrique, conique, tronconique, polyédrique, polyédrique tronquée, composé d'une grande base et d'une petite base parallèle à la grande base. Indifféremment la petite base ou la grande base est en contact avec les produits conditionnés, la grande base ou la petite base étant alors en contact avec le fond du conteneur. Le moyen de fixation est toujours solidaire de la base en contact avec le fond du conteneur, que ce soit la grande base ou la petite base. Ces deux bases sont coaxiales et sont reliées par au moins un moyen de liaison déformable sous l'effet d'une pression mécanique, et qui a capacité à recouvrer sa forme initiale lorsque ladite pression est supprimée.The compensation means of the compensation device is hollow and of apparent cylindrical, conical, frustoconical, polyhedral, truncated polyhedral form, composed of a large base and a small base parallel to the large base. Regardless, the small base or the large base is in contact with the packaged products, the large base or the small base then being in contact with the bottom of the container. The fastening means is always integral with the base in contact with the bottom of the container, whether the large base or the small base. These two bases are coaxial and are connected by at least one deformable connecting means under the effect of a mechanical pressure, and which has the ability to recover its initial shape when said pressure is removed.

La grande base et la petite base du moyen de compensation peuvent être de formes différentes ou non, mais dans tous les cas ces différentes formes doivent être insérables dans le conteneur tubulaire et adaptées à la section dudit conteneur.The large base and the small base of the compensation means may be of different shapes or not, but in all cases these different forms must be insertable into the tubular container and adapted to the section of said container.

Dans un mode de réalisation particulier, ladite section du conteneur est polygonale, elliptique ou circulaire.In a particular embodiment, said container section is polygonal, elliptical or circular.

Le moyen de compensation est de hauteur suffisante pour que son action mécanique de compensation puisse effectivement s'exercer. Ainsi, lorsque le conteneur selon l'invention est rempli ou quasi-rempli des produits conditionnés et obturé par son moyen d'obturation, le moyen de compensation exerce son action de compensation sur les produits conditionnés, de telle sorte qu'ils soient maintenus en position à l'intérieur dudit conteneur.The compensation means is of sufficient height so that its mechanical compensation action can actually be exercised. Thus, when the container according to the invention is filled or almost filled with the packaged products and closed by its sealing means, the compensation means exerts its compensation action on the packaged products, so that they are maintained in position inside said container.

La forme apparente du moyen de compensation, c'est-à-dire le volume fictif dans lequel ledit moyen de compensation est contenu, c'est-à-dire son encombrement stérique, peut être cylindrique, conique, tronconique, polyédrique ou polyédrique tronqué.The apparent shape of the compensation means, that is to say the imaginary volume in which said compensation means is contained, that is to say its steric hindrance, can be cylindrical, conical, frustoconical, polyhedral or truncated polyhedral .

Le moyen de liaison déformable de la grande base à la petite base peut être formé par :

  • au moins une hélice déformable s'enroulant sur un cylindre ou cône fictif et coaxiale à l'axe de symétrie du moyen de compensation, et apparaissant comme un ressort cylindrique, tronconique ou conique ou,
  • au moins une languette déformable apparaissant comme l'une des arêtes des faces du polyèdre fictif dans lequel s'inscrit le moyen de compensation ou appartenant à la surface fictive d'un cône ou d'un tronc de cône.
The deformable connecting means of the large base to the small base can be formed by:
  • at least one deformable helix winding on a cylinder or imaginary cone and coaxial with the axis of symmetry of the compensation means, and appearing as a cylindrical, frustoconical or conical spring or,
  • at least one deformable tongue appearing as one of the edges of the faces of the fictional polyhedron in which the compensation means is inscribed or belonging to the imaginary surface of a cone or a truncated cone.

Le moyen de compensation, lorsque contenu dans un volume fictif cylindrique, conique, tronconique, polyédrique ou polyédrique tronqué peut comporter plusieurs moyens de liaison déformables au nombre de 2, 3, 4 ou plus et disposés autour de l'axe de symétrie du moyen de compensation.
En particulier, lorsque le volume fictif est polyédrique ou polyédrique tronqué, l'une des arêtes est constituée par le au moins un moyen de liaison déformable réel, reliant la grande base à la petite base, les autres arêtes étant fictives.The compensating means, when contained in a cylindrical, conical, frustoconical, polyhedral or truncated polyhedral fictitious volume may comprise a plurality of deformable connecting means of 2, 3, 4 or more and arranged around the axis of symmetry of the means of compensation.
In particular, when the fictitious volume is truncated polyhedral or polyhedral, one of the edges is constituted by the at least one real deformable connecting means, connecting the large base to the small base, the other edges being fictitious.

De manière illustrative, quand le volume fictif est polyédrique ou polyédrique tronqué, il comporte au minimum trois surfaces latérales dont les trois arêtes réelles sont constituées par trois moyens de liaison déformables. Il en est de même pour 4 faces, 5 faces, 6 faces.Illustratively, when the fictitious volume is truncated polyhedral or polyhedral, it comprises at least three lateral surfaces whose three real edges are constituted by three deformable connecting means. It is the same for 4 faces, 5 faces, 6 faces.

Quand le au moins un moyen de liaison déformable est formé par au moins deux hélices, lesdites hélices sont à sens opposés ou non et régulièrement réparties symétriquement par rapport à l'axe de symétrie du moyen de compensation.When the at least one deformable connecting means is formed by at least two propellers, said propellers are in opposite or opposite directions and regularly distributed symmetrically with respect to the axis of symmetry of the compensation means.

Dans le cas où, par exemple, le moyen de compensation comporte trois hélices, ces hélices peuvent être de même sens, ou bien, deux hélices peuvent être dans le même sens et la troisième hélice dans l'autre sens.In the case where, for example, the compensation means comprises three helices, these helices may be in the same direction, or two helices may be in the same direction and the third helix in the other direction.

Cette au moins une hélice est reliée, par son extrémité inférieure, à l'une des bases, qui est positionnée par exemple dans le fond du conteneur. Cette au moins une hélice est également reliée, par son extrémité supérieure, à l'autre base par exemple en contact physique avec le produit conditionné.This at least one helix is connected, by its lower end, to one of the bases, which is positioned for example in the bottom of the container. This at least one helix is also connected, by its upper end, at the other base for example in physical contact with the packaged product.

La section de cette au moins une hélice peut être circulaire ou polygonale.The section of this at least one helix may be circular or polygonal.

D'autres formes d'hélices peuvent être considérées, telles que, par exemple, des hélices à contre sens de rotation ou de forme non pas strictement conique mais légèrement rhomboïde.Other forms of helix may be considered, such as, for example, propellers against rotation direction or shape not strictly conical but slightly rhomboid.

Quand le au moins un moyen de liaison déformable est formé par au moins deux languettes, lesdites languettes sont réparties symétriquement par rapport à l'axe de symétrie du moyen de compensation. Cette au moins une languette est reliée, par son extrémité inférieure à l'une des bases, par exemple la grande base, qui est positionnée par exemple au fond du conteneur, et par son extrémité supérieure à l'autre base en contact physique avec le produit conditionné.When the at least one deformable connecting means is formed by at least two tabs, said tabs are distributed symmetrically with respect to the axis of symmetry of the compensation means. This at least one tongue is connected, by its lower end to one of the bases, for example the large base, which is positioned for example at the bottom of the container, and by its upper end to the other base in physical contact with the conditioned product.

Ledit moyen de compensation assure ainsi, par sa capacité à être comprimé et par son effet ressort, le maintien en position des produits conditionnés. La section des languettes est suffisamment fine, qu'elles soient circulaires ou polygonales, pour que lesdites languettes puissent se déformer de manière réversible, sous l'effet de la pression exercée sur elles lors de la fermeture du conteneur rempli.Said compensation means thus ensures, by its ability to be compressed and by its spring effect, the holding in position of the packaged products. The section of the tongues is sufficiently thin, whether circular or polygonal, so that said tongues can deform in a reversible manner, under the effect of the pressure exerted on them during the closure of the filled container.

L'effet ressort reste entier dans le temps, dans la mesure où les déformations restent dans la plage des déformations élastiques réversibles et qu'il n'y pas fluage des matériaux constitutifs du moyen de compensation. La pression exercée sur la pile de produits conditionnés par le moyen de compensation reste inchangée.The spring effect remains intact in time, insofar as the deformations remain in the range of the reversible elastic deformations and that there is no creep of the constituent materials of the compensation means. The pressure exerted on the stack of products packaged by the compensation means remains unchanged.

Le moyen de compensation, avec sa forme apparente conique ou polyédrique déformable, mais à mémoire de forme initiale, conserve toujours sa fonction de compensateur à effet ressort.The compensation means, with its deformable conical or polyhedral apparent shape, but with initial shape memory, still retains its function of spring compensator.

Le moyen de fixationFixing means

Le dispositif de compensation comporte également un moyen de fixation.The compensation device also comprises a fixing means.

Le moyen de fixation du dispositif de compensation à mémoire de forme et présentant une capacité à déformation élastique, exerce une force de friction perpendiculaire à la paroi latérale interne du conteneur est pour ce faire formé d'éléments mécaniques, lesdits éléments mécaniques peuvent être en particulier choisis dans le groupe constitué par les ailettes, les panneaux, les lames.The fixing means of the shape memory compensating device and having an elastic deformation capacity, exerts a friction force perpendicular to the inner side wall of the container is to this end formed of mechanical elements, said mechanical elements can be in particular selected from the group consisting of fins, panels, blades.

Le moyen de fixation comporte au moins trois éléments mécaniques. Les au moins trois éléments mécaniques du moyen de fixation sont rendus solidaires du moyen de compensation tangentiellement à la périphérie de la base au contact du fond du conteneur dudit moyen de compensation et répartis symétriquement par rapport à l'axe de symétrie du dispositif de compensation, de telle sorte que l'ensemble des forces de friction qu'ils engendrent avec la paroi latérale interne du conteneur rendent solidaire le dispositif de compensation du conteneur tubulaire.The fixing means comprises at least three mechanical elements. The at least three mechanical elements of the fastening means are made integral with the compensation means tangentially to the periphery of the base in contact with the bottom of the container of said compensation means and distributed symmetrically with respect to the axis of symmetry of the compensation device, such that all of the frictional forces they generate with the inner side wall of the container make integral the compensation device of the tubular container.

Ainsi, de manière tout à fait avantageuse, une fois le dispositif de compensation positionné au fond du conteneur, ledit conteneur peut être retourné sans que le dispositif de compensation ne s'en échappe.Thus, quite advantageously, once the compensation device positioned at the bottom of the container, said container can be returned without the compensation device does not escape.

Les au moins trois éléments mécaniques du moyen de fixation, au repos et avant leur insertion dans le conteneur, définissent par leur extrémité non solidaire du moyen de compensation, un contour apparent dont la plus grande dimension, définie par la distance la plus grande entre deux points en opposition dudit contour, est comprise entre 1,1 et 2,0 fois la plus grande dimension mesurée dans le plan de section perpendiculaire à l'axe de symétrie longitudinal du conteneur.The at least three mechanical elements of the fastening means, at rest and before their insertion into the container, define by their non-integral end of the compensation means, an apparent contour whose largest dimension, defined by the largest distance between two points in opposition to said contour, is between 1.1 and 2.0 times the largest dimension measured in the sectional plane perpendicular to the longitudinal axis of symmetry of the container.

Dans le cas où la section du conteneur est polygonale, la plus grande dimension apparente est:

  • pour une section triangulaire équilatérale, l'un des côtés du triangle,
  • pour une section carrée, une diagonale,
  • pour une section rectangulaire la diagonale la plus grande,
et ce de proche en proche pour toute section polygonale.
Dans le cas où la section est elliptique, la plus grande dimension apparente est le plus grand axe elliptique.In the case where the container section is polygonal, the largest apparent dimension is:
  • for an equilateral triangular section, one of the sides of the triangle,
  • for a square section, a diagonal,
  • for a rectangular section the largest diagonal,
and this step by step for any polygonal section.
In the case where the section is elliptical, the largest apparent dimension is the largest elliptical axis.

Dans le cas où la section est circulaire, la plus grande dimension apparente est le diamètre.In the case where the section is circular, the largest apparent dimension is the diameter.

Les au moins trois éléments mécaniques du moyen de fixation, au repos et avant leur insertion dans le conteneur, définissent par leur extrémité non solidaire du moyen de compensation, un contour apparent dont la plus grande dimension, définie par la distance la plus grande entre deux points en opposition dudit contour, est préférentiellement comprise entre 1,2 et 1,6 fois la plus grande dimension mesurée dans le plan de section perpendiculaire à l'axe de symétrie longitudinal du conteneur.The at least three mechanical elements of the fastening means, at rest and before their insertion into the container, define by their non-integral end of the compensation means, an apparent outline whose most large dimension, defined by the largest distance between two points in opposition to said contour, is preferably between 1.2 and 1.6 times the largest dimension measured in the section plane perpendicular to the longitudinal axis of symmetry of the container .

Les au moins trois éléments mécaniques du moyen de fixation ont une hauteur, lorsque le dispositif de compensation est inséré dans le conteneur, au plus égale à 0,5 fois la hauteur du moyen de compensation.The at least three mechanical elements of the fastening means have a height, when the compensation device is inserted into the container, at most equal to 0.5 times the height of the compensation means.

Les au moins trois éléments mécaniques du moyen de fixation sont des parois minces formant des surfaces planes ou courbes.The at least three mechanical elements of the fastening means are thin walls forming flat or curved surfaces.

Ainsi, une fois le dispositif de compensation positionné au fond du conteneur tubulaire, les au moins trois éléments mécaniques élastiques s'étant redéployés jusqu'à être en contact surface à surface avec la paroi latérale interne du conteneur, exerce des forces de friction sur ladite paroi latérale interne, ce qui assure une tenue en position dudit dispositif de compensation dans le conteneur tubulaire.Thus, once the compensation device positioned at the bottom of the tubular container, the at least three elastic mechanical elements redeployed to be in surface-to-surface contact with the inner side wall of the container, exerts frictional forces on said internal side wall, which ensures a holding position of said compensation device in the tubular container.

Outre l'avantage mentionné ci-dessus d'une fiabilité de tenue en position au fond du conteneur de ce dispositif de compensation, et ce même en l'absence du moyen d'obturation et/ou des produits conditionnés, il est à noter les autres caractéristiques avantageuses de ce dispositif de compensation.In addition to the above-mentioned advantage of a position-holding reliability at the bottom of the container of this compensation device, even in the absence of the sealing means and / or the packaged products, it is worth noting the other advantageous features of this compensation device.

Les au moins trois éléments mécaniques du moyen de fixation peuvent éventuellement chacun comporter une protubérance en forme de segment de joncs venant s'ajuster dans une rainure correspondante positionnée sur la surface interne du conteneur. Cette association de segments de joncs et de rainure permet de fixer de manière encore plus définitive le dispositif de compensation inséré dans le conteneur.The at least three mechanical elements of the fixing means may optionally each comprise a protuberance in the form of segment of rods fitting into a corresponding groove positioned on the inner surface of the container. This combination of segments of rushes and groove makes it possible to fix even more definitively the compensation device inserted in the container.

Tout d'abord, le dispositif de compensation peut être introduit avant les produits conditionnés dans le conteneur, ou bien conjointement aux produits conditionnés.First, the compensation device can be introduced before the packaged products in the container, or in conjunction with the packaged products.

Ainsi, le déroulement des étapes de manutention du conteneur équipé de ce dispositif de compensation selon l'invention est simplifié.Thus, the steps of handling steps of the container equipped with this compensation device according to the invention is simplified.

De plus, du fait de l'élasticité des au moins trois éléments mécaniques constituant le moyen de fixation du dispositif de compensation, ce dispositif de compensation peut s'adapter à des conteneurs tubulaires de dimensions et de diamètres voisins lorsque le conteneur est de section circulaire.In addition, because of the elasticity of the at least three mechanical elements constituting the fixing means of the compensation device, this compensation device can adapt to tubular containers of similar dimensions and diameters when the container is of circular section. .

Ainsi, ce dispositif de compensation peut être intégré à différents conteneurs, offrant une souplesse d'utilisation, et permettant de se dégager de la contrainte d'élaboration d'un dispositif de compensation propre à chaque type de conteneur.Thus, this compensation device can be integrated with different containers, offering a flexibility of use, and to get rid of the constraint of developing a specific compensation device for each type of container.

Tous ces avantages mentionnés ci-dessus permettent de limiter les coûts de fabrication de conteneurs munis de ce dispositif de compensation.All these advantages mentioned above make it possible to limit the costs of manufacturing containers equipped with this compensation device.

Les matériaux polymèresPolymeric materials

D'une manière générale, le conteneur, le moyen d'obturation et le dispositif de compensation peuvent être réalisés à partir de polymères identiques ou différents.
Les polymères mis en oeuvre sont généralement choisis dans le groupe formé par les polyoléfines homo et/ou copolymères tels que les polyéthylènes, les polypropylènes, les copolymères d'éthylène/propylène mis en oeuvre seuls ou en mélange, formulés ou non.
D'autres polymères thermoplastiques peuvent également être utilisés tels que les polyamides (PA), les polystyrènes (PS), les copolymères d'acrylonitrile-butadiène-styrène (ABS), les copolymères de styrène-acrylonitrile (SAN), les polyméthacrylates de méthyl (PMMA), les polyéthylènetéréphtalates (PET), les polybutylènetéréphtalates (PBT), les polyacétals (POM), les polychlorures de vinyle (PVC), les polycarbonates (PC).In general, the container, the sealing means and the compensation device may be made from identical or different polymers.
The polymers used are generally chosen from the group formed by homo and / or copolymeric polyolefins such as polyethylenes, polypropylenes and ethylene / propylene copolymers used alone or in a mixture, formulated or not.

Ainsi, le dispositif de compensation décrit dans la présente invention simplifie la mise en oeuvre et la conception de conteneurs tubulaires destinés à conditionner des produits fragiles, tels que des comprimés pharmaceutiques, tout en assurant la fonction de tenue en position à l'intérieur dudit conteneur.Thus, the compensation device described in the present invention simplifies the implementation and design of tubular containers for packaging fragile products, such as pharmaceutical tablets, while providing the position-holding function inside said container. .

Le moyen déshydratantThe desiccant

Le conteneur tubulaire selon l'invention comprend éventuellement un moyen déshydratant qui peut être de type rapporté ou bien de type chemisage déshydratant.The tubular container according to the invention optionally comprises a desiccant means which can be of type reported or of the desiccant liner type.

Selon un autre mode de réalisation de l'invention, le dispositif de compensation peut aussi constituer un moyen déshydratant du conteneur tubulaire, s'il est fabriqué à partir d'une composition comprenant au moins une matière plastique thermoplastique ou thermodurcissable, et au moins un matériau déshydratant.According to another embodiment of the invention, the compensation device may also constitute a desiccant means of the tubular container, if it is manufactured from a composition comprising at least one thermoplastic or thermosetting plastic material, and at least one desiccant material.

Lorsque le moyen déshydratant est de type rapporté, l'agent déshydratant est placé dans un logement approprié, situé dans le bouchon, et/ou sur le fond du conteneur tubulaire, et/ou intégré au dispositif de compensation, ou faire partie intégrante du dit dispositif, ledit logement étant clos par un moyen de fermeture non étanche à l'humidité ambiante, par exemple, une membrane en carton poreux, pour assurer la dessiccation rapide des produits sensibles à l'humidité et conditionnés dans le conteneur tubulaire.When the desiccant means is of type reported, the desiccant is placed in a suitable housing, located in the cap, and / or on the bottom of the tubular container, and / or integrated in the compensation device, or an integral part of said device, said housing being closed by a sealing means not sealed to ambient humidity, for example a porous cardboard membrane, to ensure the rapid drying of the moisture-sensitive products and packaged in the container tubular.

L'agent déshydratant mis en oeuvre dans le conteneur est choisi dans le groupe constitué par les gels de silice, les tamis moléculaires ou autres produits déshydratants, se présentant sous une forme pulvérulente ou déposés sur un support pulvérulent.The dehydrating agent used in the container is selected from the group consisting of silica gels, molecular sieves or other desiccants, in powder form or deposited on a powdery support.

L'agent déshydratant peut également être une capsule contenue dans ledit logement et réalisée en un matériau polymère déshydratant contenant ou non des charges déshydratantes.The desiccant may also be a capsule contained in said housing and made of a desiccant polymer material containing or not desiccant fillers.

Lorsqu'un agent déshydratant est positionné dans un logement situé sur le fond du conteneur tubulaire, le dispositif de compensation est positionné en appui sur la membrane non étanche à l'humidité ambiante fermant le logement.When a desiccant is positioned in a housing located on the bottom of the tubular container, the compensation device is positioned in abutment on the non-moisture-tight membrane closing the housing.

Lorsque le moyen déshydratant est de type chemisage, il a alors une forme telle qu'il vient s'ajuster à l'intérieur du conteneur tubulaire. Cette forme est positionnée de manière coaxiale par rapport au conteneur, ajustée très précisément par rapport à la surface interne dudit conteneur, et pouvant glisser librement par rapport à celui-ci, ou être emmanché légèrement à force. Cette forme peut également venir en léger retrait de la surface interne du conteneur tubulaire, l'ajustement sur le conteneur se faisant alors par une pluralité de nervures longitudinales parallèles à l'axe du conteneur, assurant le centrage, ou éventuellement par l'intermédiaire de protubérances, correspondant à des nervures tronquées.When the desiccant means is of liner type, it then has a shape such that it fits inside the tubular container. This shape is positioned coaxially with respect to the container, adjusted very precisely relative to the inner surface of said container, and can slide freely relative thereto, or be forced slightly forcibly. This shape can also come in slight withdrawal from the inner surface of the tubular container, the adjustment on the container then being made by a plurality of longitudinal ribs parallel to the axis of the container, ensuring the centering, or possibly via protuberances, corresponding to truncated ribs.

Un tel chemisage peut avoir une dimension en hauteur identique à la profondeur du conteneur tubulaire et venir araser l'extrémité ouverte dudit conteneur ou être de dimension inférieure.Such a liner may have a height dimension identical to the depth of the tubular container and come to strike the open end of said container or be of smaller size.

Le chemisage peut également posséder un fond, venant ou non se poser sur le fond du conteneur tubulaire. Une cale d'espacement peut également permettre de laisser un espace entre le fond du conteneur et le fond de la chemise constituant le moyen déshydratant.The liner may also have a bottom, whether or not to land on the bottom of the tubular container. A spacer may also allow to leave a gap between the bottom of the container and the bottom of the jacket constituting the dehydrating means.

Cette chemise dessicante est fabriquée par les techniques d'injection à partir de compositions déshydratantes. Ces compositions déshydratantes sont généralement bien connues et amplement décrites sous la forme de compositions thermoplastiques injectables comprenant des matériaux polymères auxquels ont été incorporés des produits déshydratants.This desiccant liner is manufactured by injection techniques from desiccant compositions. These desiccant compositions are generally well known and widely described in the form of injectable thermoplastic compositions comprising polymeric materials into which desiccants have been incorporated.

Lorsque le moyen déshydratant est de type chemisage, le moyen de fixation du dispositif de compensation exerce des forces de friction sur la chemise déshydratante.When the desiccant means is of liner type, the fixing means of the compensation device exerts frictional forces on the desiccant liner.

Dans le mode de réalisation de l'invention pour lequel le dispositif de compensation est aussi un moyen déshydratant, ledit moyen déshydratant est réalisé avec les mêmes polymères et matériaux déshydratants que ceux mis en oeuvre pour la réalisation de la chemise déshydratante.In the embodiment of the invention for which the compensation device is also a dehydrating means, said desiccant means is made with the same polymers and desiccant materials as those implemented for the production of the desiccant jacket.
