Description

L'invention a pour objet un emballage pour joints. Elle concerne plus particulièrement un emballage pour joints, par exemple de forme ronde, destinés à être logés dans le fond d'un bouchon ou équivalent. Elle a également pour objet un procédé de fabrication de l'emballage contenant lesdits joints.The invention relates to a packaging for joints. It relates more particularly to a packaging for joints, for example of round shape, intended to be housed in the bottom of a plug or equivalent. It also relates to a method of manufacturing the package containing said seals.

L'obturation de récipients par bouchons, préalablement à leur première ouverture, est effectuée au moyen d'un joint qui peut être scellable, par exemple thermiquement, ou collable. Cette obturation est obtenue d'une part par la coopération d'un opercule mis en place sur tout le pourtour du rebord supérieur du col du récipient ou buvant, isolant de la sorte le récipient de l'extérieur, et d'autre part, par un support généralement plus épais, inséré sans être pour autant fixé au fond du bouchon, celui-ci venant donc se fixer à l'extrémité supérieure du col dudit récipient.The closure of containers by plugs, prior to their first opening, is performed by means of a seal which can be sealable, for example thermally, or bondable. This obturation is obtained on the one hand by the cooperation of a lid placed on the entire periphery of the upper rim of the neck of the container or drinking, thus isolating the container from the outside, and on the other hand, by a generally thicker support, inserted without being fixed to the bottom of the cap, the latter thus being attached to the upper end of the neck of said container.

L'invention concerne plus particulièrement l'emballage de ces supports en vue de leur mise en place dans le tube d'une machine de distribution de joints.The invention relates more particularly to the packaging of these supports for their introduction into the tube of a seal dispensing machine.

En effet et en pratique, le fabricant de joints n'est en général pas le conditionneur du produit. Dès lors, les joints sont vendus au conditionneur qui a la charge de positionner les joints dans les couvercles. En pratique, cette association est effectuée de manière automatisée en introduisant préalablement les joints dans le tube d'une machine distributrice de joints. En général, la paroi du tube destinée à recevoir les joints est discontinue, de manière à permettre à l'utilisateur d'avoir accès à ladite colonne en cas de mauvais positionnement des joints.Indeed and in practice, the seal manufacturer is generally not the conditioner of the product. Therefore, the seals are sold to the conditioner who is responsible for positioning the seals in the covers. In practice, this combination is performed automatically by introducing the seals in the tube of a seal dispensing machine. In general, the wall of the tube intended to receive the joints is discontinuous, so as to allow the user to have access to said column in case of poor positioning of the joints.

A la connaissance du Demandeur, les joints sont actuellement emballés dans des gaines en plastique hermétiquement fermées. Ce type de solution nécessite de couper avec un outil une des extrémités de la gaine. Les joints dans la gaine ouverte sont introduits dans le tube et la gaine est retirée par traction vers le haut. Cette action peut parfois endommager ou retourner un joint dans la colonne. Parfois, des cartouches de papier sont utilisées comme emballage, à l'instar de ce que l'on connaît pour les pièces de monnaie. Un inconvénient réside dans la nature du papier qui ne remplit pas les conditions d'hygiène nécessaires pour l'emballage alimentaire.To the Applicant's knowledge, the seals are currently packaged in hermetically sealed plastic sheaths. This type of solution requires cutting with one tool one end of the sheath. The joints in the open sheath are introduced into the tube and the sheath is withdrawn by pulling upwards. This action can sometimes damage or return a seal in the column. Sometimes, paper cartridges are used as packaging, just like what is known for coins. A disadvantage is the nature of the paper which does not fulfill the hygienic conditions necessary for food packaging.

Le document US-A-6 045 641 décrit une méthode pour fabriquer un manchon en matériau thermorétractable muni d'une prédécoupe longitudinale. Le manchon est dépourvu de fermetures à ses extrémités et ne concerne pas l'emballage de produits spécifiques.The document US-A-6,045,641 describes a method for manufacturing a sleeve of heat-shrinkable material provided with a longitudinal precut. The sleeve has no closures at its ends and does not concern the packaging of specific products.

En d'autres termes, la solution décrite dans ce document ne peut pas être transposée pour l'emballage de joints, dans la mesure où aucune retenue des joints découpés n'est assurée pour les manipulations et pendant le stockage. En outre, l'absence de fermeture au niveau des extrémités ne permet pas de garantir l'intégrité du joint, tant chimiquement que physiquement.In other words, the solution described in this document can not be transposed for the packing of joints, insofar as no restraint of the cut joints is ensured for handling and during storage. In addition, the lack of closure at the ends does not ensure the integrity of the joint, both chemically and physically.

Le document JP2002173174 décrit un emballage plastique destiné à contenir des produits alimentaires visqueux du type par exemple, margarine ou pâte de soja. L'emballage présente des languettes latérales qui sont rompues par déchirement à partir d'une amorce prévue à l'extrémité de la bandelette longitudinale. C'est seulement ensuite que les deux parties constitutives de la bandelette longitudinale scellées sont désolidarisées pour permettre l'ouverture complète du produit. L'ouverture est en outre favorisée par la présence de prédécoupes traversantes ménagées sur la surface de la bandelette longitudinale, avantageusement sur toute leur longueur.The document JP2002173174 discloses a plastic package for containing viscous food products of the type for example, margarine or soy paste. The package has side tabs that are ruptured by tearing from a primer provided at the end of the longitudinal strip. Only then the two constituent parts of the longitudinal strip sealed are separated to allow the complete opening of the product. The opening is further favored by the presence of through precuts formed on the surface of the longitudinal strip, preferably over their entire length.

Le problème posé est donc de développer un emballage pour joints qui puisse être facilement manipulable pour le conditionneur et qui garantisse l'intégrité des joints qu'il contient.The problem is therefore to develop a seal package that can be easily handled for the conditioner and that ensures the integrity of the joints it contains.

Pour ce faire, le Demandeur a eu l'idée, en lieu et place des emballages papier et gaines plastiques hermétiques aujourd'hui utilisés, de mettre en oeuvre un film plastique muni d'une languette de préhension longitudinale prédécoupée et dont au moins une des extrémités est fermée pour définir également une languette de préhension prédécoupée.To do this, the Applicant has had the idea, in place of hermetic plastic paper packaging and cladding today used, to implement a plastic film provided with a pre-cut longitudinal gripping tab and at least one of ends is closed to also define a pre-cut grip tab.

Plus précisément, l'invention a pour objet un emballage pour joints destinés à être logés dans le fond d'un bouchon ou équivalent, constitué d'une gaine réalisée en matière plastique à partir d'une feuille, la gaine étant munie sur toute sa longueur, d'une languette de préhension longitudinale obtenue par association des deux extrémités longitudinales de la feuille, et sur au moins une des ses deux largeurs, d'une languette latérale obtenue par association des deux extrémités latérales correspondantes de la feuille, caractérisé en ce que la gaine présente des prédécoupes agencées en dessous des languettes latérales et longitudinales.More specifically, the invention relates to a packaging for seals intended to be housed in the bottom of a plug or equivalent, consisting of a sheath made of plastic material from a sheet, the sheath being provided over its entire length. length, a longitudinal gripping tab obtained by combining the two longitudinal ends of the sheet, and on at least one of its two widths, a lateral tab obtained by association of the two corresponding lateral ends of the sheet, characterized in that that the sheath has pre-cuts arranged below the lateral and longitudinal tongues.

Autrement dit, la feuille présente des prédécoupes situées sur au moins trois de ses quatres cotés, à proximité des extrémités des sorte que, une fois repliée sur elle-même pour former la gaine, les prédécoupes soient situées en dessous des languettes latérale et longitudinale, c'est-à-dire à l'intérieur de l'emballage.In other words, the sheet has precuts located on at least three of its four sides, near the ends so that, once folded on itself to form the sheath, the pre-cuts are located below the lateral and longitudinal tabs, that is to say inside the package.

De la sorte, cette configuration permet au conditionneur, lorsqu'il reçoit les joints emballés, de facilement ouvrir une extrémité de la gaine sans outil coupant, avant de l'introduire directement dans le tube de la machine distributrice de joints. L'utilisateur rompt ensuite la languette latérale de préhension supérieure puis, après rupture de la languette de préhension longitudinale, retire facilement le reste de la matière plastique, sans avoir à la retirer par le haut du tube. Les risques d'endommager les joints lors du retrait de l'emballage sont quasi inexistants.In this way, this configuration allows the packager, when receiving the packaged seals, to easily open one end of the sheath without cutting tool, before introducing it directly into the tube of the machine dispenser seals. The user then breaks the upper lateral gripping tab and, after breaking the longitudinal gripping tab, easily removes the rest of the plastic without having to remove it from the top of the tube. The risk of damaging the seals when removing the packaging is almost non-existent.

Dans un mode de réalisation avantageux, chaque extrémité présente une languette de préhension latérale prédécoupée.In an advantageous embodiment, each end has a pre-cut lateral gripping tongue.

De préférence, la prédécoupe est réalisée sur toute la longueur de la languette latérale sur chacune des deux extrémités de la feuille.Preferably, the precut is performed along the entire length of the lateral tongue on each of the two ends of the sheet.

Selon une autre caractéristique, l'association des extrémités longitudinales et latérales de la feuille entre elles est obtenue par soudure.According to another characteristic, the combination of the longitudinal and lateral ends of the sheet between them is obtained by welding.

Bien entendu, la forme de l'emballage peut être adaptée en fonction du diamètre des joints et éventuellement de la forme des joints.Of course, the shape of the package can be adapted according to the diameter of the joints and possibly the shape of the joints.

L'invention a également pour objet un procédé pour la fabrication d'un emballage contenant des joints destinés à être logés dans le fond d'un bouchon ou équivalent.The invention also relates to a process for the manufacture of a package containing seals intended to be housed in the bottom of a plug or equivalent.

Selon ce procédé :

  • on dépose sur une feuille plastique, une succession de joints en contact avec ladite feuille par leur tranche,
  • on replie ensuite la feuille autour du tube formé par les joints,
  • on soude, on perfore en dessous de la ligne de soudure et on coupe simultanément ou non au dessus de la ligne de soudure les deux bords longitudinaux de la feuille pour former une languette de préhension prédécoupée,
  • simultanément ou ultérieurement, on soude, puis on coupe les bords latéraux, dont au moins un est préalablement prédécoupé en dessous de la ligne de soudure.
According to this method:
  • depositing on a plastic sheet, a succession of joints in contact with said sheet by their edge,
  • the sheet is then folded around the tube formed by the joints,
  • welded, perforated below the weld line and cut simultaneously or not above the weld line the two longitudinal edges of the sheet to form a pre-cut gripping tongue,
  • simultaneously or later, is welded and then cut the side edges, at least one is precut previously below the weld line.

Dans un mode de réalisation avantageux, le procédé est mis en oeuvre en continu à partir d'une bobine de matière plastique.In an advantageous embodiment, the process is carried out continuously from a plastic spool.

Lorsque la longueur de la feuille plastique est adaptée à la longueur correspondant à la succession des joints, les languettes de préhension latérales n'ont pas besoin d'être coupées et sont simplement soudées, une au moins étant prédécoupée en dessous de la ligne de soudure.When the length of the plastic sheet is adapted to the length corresponding to the succession of joints, the lateral gripping tongues do not need to be cut and are simply welded, at least one being precut below the weld line .

Bien entendu, l'emballage plastique peut être réalisé au moyen de tout matériau connu de l'homme du métier, en particulier les matériaux comportant une face soudable, comme le polyéthylène ou le polypropylène.Of course, the plastic package can be made using any material known to those skilled in the art, especially materials having a weldable face, such as polyethylene or polypropylene.

L'invention et les avantages qui en découlent ressortiront mieux des exemples de réalisation suivant à l'appui des figures annexées.

  • La figure 1 est une illustration de l'emballage vue de profil.
  • La figure 2 est une coupe de la figure 1 selon A-A'.
The invention and the advantages resulting therefrom will emerge more clearly from the following exemplary embodiments in support of the appended figures.
  • Figure 1 is an illustration of the package seen in profile.
  • Figure 2 is a section of Figure 1 according to A-A '.

Selon l'invention, l'emballage identifié par la référence générale (1) est constitué d'une gaine (2) dans laquelle sont positionnés des joints de forme ronde comportant éventuellement une ou plusieurs languettes (3), lesquels sont destinés à être introduits dans le fond de couvercles de bocaux. Ces joints sont empilés pour remplir une partie du volume de la gaine (2). Cette gaine (2) présente deux extrémités libres (4, 5) formant des languettes de préhension latérales, ainsi qu'une languette de préhension longitudinale.According to the invention, the packaging identified by the general reference (1) consists of a sheath (2) in which are positioned round-shaped seals optionally comprising one or more tongues (3), which are intended to be introduced in the bottom of jar lids. These seals are stacked to fill part of the volume of the sheath (2). This sheath (2) has two free ends (4, 5) forming lateral gripping tabs, and a longitudinal gripping tab.

Plus précisément, l'emballage est obturé longitudinalement et latéralement par des lignes de soudure, respectivement (6, 7 et 8). Entre la ligne de soudure et les joints, sont ménagées des prédécoupes (9, 10, 11) permettant de séparer les languettes de préhension latérales et longitudinales de la gaine, de manière à permettre la libération des joints.More specifically, the package is closed longitudinally and laterally by welding lines, respectively (6, 7 and 8). Between the weld line and the joints are provided precuts (9, 10, 11) for separating the lateral and longitudinal gripping tabs of the sheath, so as to allow the release of the joints.

Sur la figure 2, on a représenté une coupe selon la ligne A-A de la figure 1. Sur cette coupe, on constate que la feuille plastique est munie, sur sa partie longitudinale, de deux prédécoupes (9-1 et 9-2) permettant une séparation facile de la languette de préhension longitudinale du reste de la gaine.FIG. 2 shows a section along line AA of FIG. 1. On this section, it can be seen that the plastic sheet is provided, on its longitudinal portion, with two pre-cuts (9-1 and 9-2) allowing easy separation of the longitudinal gripping tab from the rest of the sheath.

En pratique, le conditionneur reçoit les joints emballés. Il ouvre une des extrémités de la gaine prédécoupée sans outil coupant. Il positionne ensuite l'emballage et les joints dans le tube de la machine distributrice de joints. Une fois mis en place, il tire la languette de préhension latérale supérieure ainsi que la languette de préhension longitudinale, de manière à ouvrir la gaine d'emballage et à retirer la matière plastique à travers les lumières de la paroi latérale du tube distributeur.In practice, the conditioner receives the packaged joints. It opens one end of the pre-cut sheath without cutting tools. It then positions the package and seals in the tube of the seal dispensing machine. Once in place, it pulls the upper side grip tab and the longitudinal grip tab, so as to open the packaging sheath and remove the plastic material through the lumens of the side wall of the dispenser tube.

L'invention a également pour objet le procédé de fabrication en continu ou discontinu de l'emballage contenant les joints.The invention also relates to the continuous or discontinuous manufacturing process of the package containing the seals.

En pratique, les joints sont disposés sur une feuille en matière plastique provenant directement de la bobine. Une fois les joints mis en place, la feuille est repliée sur les joints de manière à former une gaine, dont les deux extrémités longitudinales sont ensuite simultanément perforées en dessous de la ligne de soudure et thermosoudées. A l'issue de cette étape, la gaine est découpée sur toute sa longueur au dessus de la ligne de soudure. Parallèlement, les extrémités latérales de l'emballage sont également thermosoudées et perforées en dessous de la ligne de soudure.In practice, the seals are arranged on a sheet of plastic material coming directly from the reel. Once the seals are in place, the sheet is folded over the joints to form a sheath, the two longitudinal ends are then simultaneously perforated below the weld line and heat sealed. At the end of this step, the sheath is cut along its entire length above the weld line. Meanwhile, the lateral ends of the package are also heat sealed and perforated below the weld line.

L'invention et les avantages qui en découlent ressortent bien de la description qui précède. On notera en particulier la mise en oeuvre facile de l'emballage pour l'utilisateur avec une plus grande sécurité pour l'opérateur, et moins de risque d'endommager les joints lors du déballageThe invention and the advantages derived therefrom are apparent from the foregoing description. Of particular note is the easy implementation of the package for the user with greater safety for the operator, and less risk of damaging the seals during unpacking
