Abstract
Description
L'invention concerne un procédé pour la réalisation d'un emballage tel qu'une barquette de conditionnement pour produits alimentaires. The invention relates to a method for producing a package such as a packaging tray for food products.
On connaît déjà les barquettes qui se composent de deux coques de matière plastique thermoformées, qui sont disposées l'une dans l'autre avec interposition d'une étiquette. Dans ce cas, au moins la matière plastique constituant la coque extérieure, est transparente, de façon à rendre visible l'inscription de l'étiquette disposée en sandwich entre les deux coques et qui se trouve ainsi convenablement maintenue et protégée. We already know the trays which consist of two thermoformed plastic shells, which are arranged one inside the other with the interposition of a label. In this case, at least the plastic material constituting the outer shell is transparent, so as to make visible the inscription of the label sandwiched between the two shells and which is thus suitably maintained and protected.
Ce procédé de fabrication est cependant onéreux, dans la mesure où il nécessite la fabrication de deux coques, avec des machines spécifiques et coûteuses et, en outre, les emballages obtenus ne sont pas de bonne qualité dans la mesure où la matière plastique utilisée ne permet pas d'obtenir des emballages présentant une bonne tenue à la température et une bonne résistance à la déformation. This manufacturing process is however expensive, insofar as it requires the manufacture of two shells, with specific and expensive machines and, moreover, the packaging obtained is not of good quality insofar as the plastic material used does not allow not to obtain packaging with good temperature resistance and good resistance to deformation.
La présente invention a notamment pour but de remédier à ces inconvénients et concerne à cet effet un procédé pour la réalisation d'un emballage tel qu'une barquette de conditionnement pour produits alimentaires, caractérisé en ce qu'on met en oeuvre une feuille de matériau souple pourvue d'une décoration et/ou de références d'identification sur l'une de ses faces, on dispose cette feuille dans un moule d'injection et on injecte dans ce moule une matière plastique transparente afin de surmouler cette matière plastique sur la face de la feuille pourvue de la décoration, la matière plastique surmoulée étant de nature et/ou d'épaisseur telle qu'elle constitue la structure de rigidification de l'emballage. The present invention aims in particular to remedy these drawbacks and for this purpose relates to a method for producing a package such as a packaging container for food products, characterized in that a sheet of material is used flexible provided with a decoration and / or identification references on one of its faces, this sheet is placed in an injection mold and a transparent plastic material is injected into this mold in order to overmold this plastic material on the face of the sheet provided with the decoration, the overmolded plastic being of a nature and / or thickness such that it constitutes the stiffening structure of the packaging.
Suivant une autre caractéristique de l'invention, on met en forme la feuille souple de façon qu'elle définisse tout ou partie de la paroi interne de l'emballage et on surmoule la matière plastique sur cette feuille mise en forme. According to another characteristic of the invention, the flexible sheet is shaped so that it defines all or part of the internal wall of the packaging and the plastic is overmolded on this shaped sheet.
L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels
- la figure 1 est une vue en coupe schématique d'un emballage conforme à l'invention,
- la figure 2 est une vue en perspective de cet emballage.The invention is shown by way of non-limiting example in the accompanying drawings in which
FIG. 1 is a schematic sectional view of a package according to the invention,
- Figure 2 is a perspective view of this package.
La présente invention a en conséquence pour but la réalisation d'un emballage simple et peu onéreux, dans la mesure où il permet la décoration ou l'étiquetage de l'emballage, simultanément à sa fabrication, cette décoration et cet étiquetage étant par ailleurs convenablement fixés pour ne pas être déplacés par les produits que contient l'emballage et, également, sans pouvoir être arrachés ou détériorés de l'extérieur de cet emballage. The present invention therefore aims to achieve a simple and inexpensive packaging, insofar as it allows the decoration or labeling of the packaging, simultaneously with its manufacture, this decoration and this labeling being moreover suitably fixed so as not to be moved by the products contained in the packaging and, also, without being able to be torn off or damaged from the outside of this packaging.
Suivant l'invention, il est ainsi prévu de réaliser l'emballage tel que la barquette 1, par injection d'une matière plastique transparente, le moule d'injection recevant, préalablement à l'inJection, de la matière plastique, une feuille de matériau souple pourvue d'une décoration ou des références d'identification du produit emballé, de façon que la matière plastique pâteuse recouvre la face décorée de la feuille en assurant donc, après solidification, son positionnement. According to the invention, it is thus planned to produce the packaging such as the tray 1, by injection of a transparent plastic material, the injection mold receiving, prior to injection, the plastic material, a sheet of flexible material provided with a decoration or identification references of the packaged product, so that the pasty plastic material covers the decorated face of the sheet thus ensuring, after solidification, its positioning.
Suivant cette réalisation, la feuille de matériau souple forme donc tout ou partie de la face interne de l'emballage, dont la face extérieure est constituée par la matière plastique transparente, de façon à rendre visible la décoration ou les références d'étiquetage du produit emballé. According to this embodiment, the sheet of flexible material therefore forms all or part of the internal face of the packaging, the external face of which is formed by transparent plastic, so as to make the decoration or the labeling references of the product visible. packed up.
Afin de favoriser la jonction mecanique de la face externe décorée de la feuille souple et de la matière plastique à l'état pâteux, on prévoira, de préférence, un laquage sur cette face décorée de la feuille souple, de façon que cette laque se ramollisse au contact de la matière plastique chaude et assure une bonne jonction mécanique de la feuille souple et de la matière plastique après solidification de cette dernière. In order to favor the mechanical junction of the external face decorated with the flexible sheet and the plastic material in the pasty state, provision will preferably be made for lacquering on this decorated side of the flexible sheet, so that this lacquer softens in contact with the hot plastic and ensures good mechanical joining of the flexible sheet and the plastic after solidification of the latter.
Dans l'exemple représenté, la feuille de matériau souple 2 est une feuille qui recouvre la totalité de la face interne de l'emballage. Cette feuille, constituée par exemple par une feuille d'aluminium, est mise en forme par plissage à hauteur de ses angles 3, les plis couchés de la feuille d'aluminium étant convenablement maintenus par la liaison mécanique de la feuille et de la matière plastique transparente. In the example shown, the sheet of flexible material 2 is a sheet which covers the entire internal face of the packaging. This sheet, constituted for example by an aluminum sheet, is shaped by pleating at the height of its angles 3, the folded folds of the aluminum sheet being suitably maintained by the mechanical connection of the sheet and the plastic material. transparent.
Cette feuille d'aluminium pourra comporter une décoration sur la totalité de sa face externe, dans la mesure où la nature de cette décoration est telle qu'elle n'est pas détruite par les plissages de la feuille à hauteur des angles de l'emballage. Dans ce cas cependant, les références d'identification seront prévues sur les faces planes latérales et/ou de fond, afin de ne pas être déformées par le plissage de la feuille. This aluminum sheet may include a decoration on the whole of its external face, insofar as the nature of this decoration is such that it is not destroyed by the folds of the sheet at the corners of the packaging. . In this case, however, the identification references will be provided on the flat side and / or bottom faces, so as not to be deformed by the pleating of the sheet.
On notera donc que, suivant l'invention, la feuille de matériau souple est conçue pour servir de support à la décoration et pour pouvoir venir en contact avec le produit emballé et, notamment, un produit alimentaire, alors que la structure de l'emballage lui-même est obtenue par une matière plastique transparente injectée qui ne comporte pas en elle-même la décoration et qui ne vient en contact avec le produit emballé que dans les zones laissées éventuellement libres par la feuille de matériau souple. It will therefore be noted that, according to the invention, the sheet of flexible material is designed to serve as a support for decoration and to be able to come into contact with the packaged product and, in particular, a food product, while the structure of the packaging itself is obtained by an injected transparent plastic material which does not in itself contain the decoration and which comes into contact with the packaged product only in the zones possibly left free by the sheet of flexible material.
Dans le cas de la mise en oeuvre d'une feuille d'aluminium, celle-ci recouvrira préférablement la totalité de la face interne de l'emballage, comme cela est représenté sur les dessins ci-joints, afin d'obtenir un emballage de bonne tenue mécanique, pourvu d'une décoration convenablement protégée de l'extérieur et qui offre de bonnes qualités barrières aux gaz et aux rayonne- ments ultra-violet et cela même à hauteur des angles de l'emballage dans lesquels se situent les plis 3 de la feuille d'aluminium. In the case of the implementation of an aluminum foil, this will preferably cover the entire internal face of the package, as shown in the attached drawings, in order to obtain a packaging of good mechanical strength, with a decoration suitably protected from the outside and which offers good barrier qualities to gases and ultra-violet radiation, even at the corners of the packaging in which the folds are located 3 aluminum foil.
