Abstract

The packaging tray is made from cardboard (1) and has a plastic lining (4) which is heat molded inside it. It is then stuck to the surface by strips of adhesive (3) which allow it to be removed subsequently so that the tray can be recycled. An Independent claim is included for a method for making the tray.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne une barquette étanche recyclable. Elle est constituée d'une enveloppe externe réalisée en un matériau d'emballage relativement rigide comme par exemple du carton et d'un doublage intérieur réalisé au moyen d'un film plastique thermoformé qui assure l'étanchéité de la barquette.  The present invention relates to a recyclable waterproof tray. It consists of an outer envelope made of a relatively rigid packaging material such as cardboard and an inner lining made by means of a thermoformed plastic film which seals the tray.

Le film de doublage étant particulièrement mince, il est généralement assemblé sur la face interne de l'enveloppe. Cet assemblage est réalisé par soudure à l'aide d'un adhésif qui est réactivé par la chaleur du film plastique au moment du thermoformage. Cet adhésif est déposé préalablement soit sur toute la surface interne du matériau composant l'enveloppe, soit sur le film plastique, soit encore sur les deux.  The lining film being particularly thin, it is generally assembled on the internal face of the envelope. This assembly is carried out by welding using an adhesive which is reactivated by the heat of the plastic film at the time of thermoforming. This adhesive is deposited beforehand either on the entire internal surface of the material making up the envelope, or on the plastic film, or else on both.

Cette technique est relativement coûteuse et elle est surtout incompatible avec les techniques de recyclage des matériaux. En effet, il est pratiquement impossible de séparer la doublure plastique de l'enveloppe externe du fait de la soudure des matériaux. Or dans ce type de barquette, l'enveloppe externe constitue la majeure partie de ce qui est recyclable.  This technique is relatively expensive and is above all incompatible with techniques for recycling materials. Indeed, it is practically impossible to separate the plastic lining from the external envelope due to the welding of the materials. However, in this type of tray, the external envelope constitutes the major part of what is recyclable.

La présente invention propose une barquette qui remédie à ces inconvénients, facilitant le recyclage de l'un au moins des matériaux.  The present invention provides a tray which overcomes these drawbacks, facilitating the recycling of at least one of the materials.

La barquette selon l'invention est constituée d'une enveloppe en un matériau du genre carton, doublée intérieurement d'un film plastique étanche qui est thermoformé sur ladite enveloppe et ce film plastique est solidaire de ladite enveloppe par une ou plusieurs zones de collage dont la surface est telle qu'elle permet une séparation pratique des deux matériaux constitutifs avec une force particulièrement réduite et qui surtout, limite la quantité de matière arrachée à l'enveloppe.  The tray according to the invention consists of an envelope of a cardboard-like material, lined internally with a waterproof plastic film which is thermoformed on said envelope and this plastic film is integral with said envelope by one or more bonding zones, the surface is such that it allows a practical separation of the two constituent materials with a particularly reduced force and which above all, limits the amount of material torn from the envelope.

L'invention concerne également le procédé de façonnage de la barquette qui est constituée d'une partie externe formant enveloppe réalisée en matériau du genre carton et d'un doublage interne en forme de film plastique thermoformé directement dans ladite enveloppe qui a été préalablement mise en volume, lequel procédé consiste, avant de réaliser l'opération de thermoformage du doublage plastique, à projeter sur la surface interne de ladite enveloppe de la colle dans des emplacements judicieusement choisis pour obtenir un bon maintien du doublage dans ladite enveloppe.  The invention also relates to the method of shaping the tray which consists of an outer part forming an envelope made of material of the cardboard type and an inner lining in the form of a thermoformed plastic film directly in said envelope which has been previously placed volume, which method consists, before carrying out the thermoforming operation of the plastic lining, to spray onto the internal surface of said envelope of the adhesive in judiciously chosen locations to obtain good retention of the lining in said envelope.

L'invention sera encore détaillée à l'aide de la description suivante et des dessins annexés donnés à titre indicatif et dans lesquels : - la figure 1 montre d'une façon schématique, les différentes étapes du procédé selon l'invention ; - la figure 2 montre la séparation des deux matériaux constitutifs de la barquette.  The invention will be further detailed with the aid of the following description and of the appended drawings given by way of indication and in which: FIG. 1 schematically shows the different steps of the method according to the invention; - Figure 2 shows the separation of the two constituent materials of the tray.

La figure 1 montre les différentes étapes de fabrication de la barquette.
L'étape A présente l'enveloppe externe 1 d'une barquette. Cette enveloppe externe 1 est réalisée en matériau approprié, de préférence du carton et cette enveloppe est élaborée soit à partir d'un flan classique mis en volume, soit par moulage de pâte à papier par exemple. La nature et l'épaisseur du matériau de l'enveloppe sont choisies selon les dimensions de la barquette et sa destination. Figure 1 shows the different stages of manufacturing the tray.
Step A presents the outer envelope 1 of a tray. This outer envelope 1 is made of an appropriate material, preferably cardboard and this envelope is produced either from a conventional blank set in volume, or by molding paper pulp for example. The nature and thickness of the envelope material are chosen according to the dimensions of the tray and its destination.

L'étape B représente l'enveloppe externe 1 de la barquette et les moyens 2 qui permettent de projeter à l'endroit le plus approprié de la surface interne de l'enveloppe 1, de la colle avec les moyens usuels appropriés. Les zones de collage 3 peuvent se situer indifféremment sur les cotés et/ou le fond.  Step B represents the outer envelope 1 of the tray and the means 2 which make it possible to spray, at the most appropriate place on the inner surface of the envelope 1, adhesive with the usual usual means. The bonding zones 3 can be located either on the sides and / or the bottom.

L'étape C correspond à la mise en place du film plastique 4 au moyen d'une matrice 5 de thermoformage par exemple, ou toute autre technique classique.  Step C corresponds to the establishment of the plastic film 4 by means of a thermoforming matrix 5 for example, or any other conventional technique.

Le film plastique 4 est mis en volume directement dans l'enveloppe 1 par thermoformage, laquelle enveloppe 1 est préalablement disposée dans une matrice appropriée non représentée.  The plastic film 4 is placed in volume directly in the envelope 1 by thermoforming, which envelope 1 is previously arranged in a suitable matrix, not shown.

L'étape D montre le produit fini c'est-à-dire la barquette qui est constituée de son enveloppe externe 1 doublée intérieurement d'un film plastique 4 thermoformé, lequel film 4 est maintenu au moyen d'une ou de plusieurs zones de collage 3.  Step D shows the finished product, that is to say the tray which consists of its outer casing 1 lined internally with a thermoformed plastic film 4, which film 4 is maintained by means of one or more zones of collage 3.

Ainsi, pour le recyclage, comme représenté figure 2, on remarque que le doublage interne constitué du film plastique 4, se sépare facilement de l'enveloppe externe 1 de la barquette. Ce doublage n'étant retenu que par un ou quelques points de collage 3.  Thus, for recycling, as shown in Figure 2, we note that the inner lining consisting of the plastic film 4, is easily separated from the outer casing 1 of the tray. This doubling being retained only by one or a few bonding points 3.

La surface de ce ou de ces zones de collage 3 est particulièrement réduite ce qui a tout d'abord comme principal avantage de réduire  The surface of this or these bonding zones 3 is particularly reduced, which first of all has the main advantage of reducing

<Desc/Clms Page number 3><Desc / Clms Page number 3>

considérablement les efforts nécessaires pour séparer les deux matériaux constituant la barquette. Cette ou ces zones de collage, à faible surface, limitent également la quantité de matière susceptible d'être arrachée comme par exemple une portion de carton restant collée à la partie plastique. considerably the efforts necessary to separate the two materials constituting the tray. This or these bonding zones, with a small surface area, also limit the quantity of material capable of being torn off, such as for example a portion of cardboard which remains bonded to the plastic part.
