Description
Garniture stratifiée monobloc non isolante et son Procédé de fabrication.Non-insulating monobloc laminate trim and its manufacturing process.
La présente invention concerne une garniture stratifiée monobloc non isolante destinée à être placée dans, ou à constituer, le fond d'emballages alimentaires pour l'absorption des exsudats s'écoulant du contenu.The present invention relates to a non-insulating one-piece laminate lining intended to be placed in, or to constitute, the bottom of food packaging for the absorption of exudates flowing from the contents.
De nombreuses barquettes existent à ce jour pour permettre la conservation de produits alimentaires. Ces barquettes présentent cependant un certain nombre d'inconvénients. En effet, elles ne permettent pas toujours d'éviter un contact entre l'exsudat et le produit alimentaire, en particulier lors du retournement ou du conditionnement du produit. En outre, en raison des matériaux utilisés, le produit alimentaire est isolé de l'environnement extérieur, empêchant tout transfert thermique, en particulier tout refroidissement de sa face en contact avec le matériau de conditionnement. De ce fait, on crée à l'intérieur du produit un gradient de température défavorable à la conservation de ce dernier. On constate en effet souvent que la température de la face du dessus du produit alimentaire est inférieure à celle de la face du dessous. Parmi les problèmes précités, certains ont été résolus au moyen de garnitures ou de barquettes de conditionnement appropriées.Many trays exist to date to allow the conservation of food products. These trays, however, have a number of drawbacks. Indeed, they do not always make it possible to avoid contact between the exudate and the food product, in particular during the turning or packaging of the product. In addition, due to the materials used, the food product is isolated from the external environment, preventing any heat transfer, in particular any cooling of its face in contact with the packaging material. Therefore, a temperature gradient unfavorable for the preservation of the latter is created inside the product. It is often found that the temperature of the top face of the food product is lower than that of the bottom face. Among the above-mentioned problems, some have been solved by means of suitable packings or packaging trays.
Ainsi, le brevet FR-A-2.586.653 décrit une barquette de conditionnement munie d'un double fond et comportant des moyens pour tenir l'aliment éloigné de l'exsudat. Le double fond de cette barquette est constitué d'une couche supérieure perforée généralement en matière plastique, d'une couche intermédiaire réalisée en un matériau absorbant, ledit matériau absorbant étant enveloppé d'une couche d'air de manière à ne pas gêner son gonflement lorsqu'il est imprégné d'exsudat et une couche inférieure cannelée en matière plastique imperméable, lesdites cannelures ayant pour fonction d'une part de constituer le support du matériau absorbant, d'autre part, de récupérer l'exsudat dans leur fond. Une telle barquette, si elle répond au problème de l'isolement de l'exsudat par rapport au produit alimentaire, ne constitue en aucun cas un ensemble recyclable et présente en outre un coût de fabrication élevé.Thus, patent FR-A-2,586,653 describes a packaging container provided with a double bottom and comprising means for keeping the food away from the exudate. The double bottom of this tray consists of a perforated upper layer generally made of plastic, an intermediate layer made of an absorbent material, said absorbent material being enveloped with a layer of air so as not to hinder its swelling. when it is impregnated with exudate and a grooved lower layer of impermeable plastic, said grooves having the function on the one hand of constituting the support for the absorbent material, on the other hand, of recovering the exudate at their bottom. Such a tray, if it responds to the problem of isolating the exudate from the food product, does not in any way constitute a recyclable assembly and also has a high manufacturing cost.
Une autre garniture est décrite dans le brevet FR-A-2.578.512.Another packing is described in patent FR-A-2,578,512.
Cette garniture affecte la forme d'un coussin constituant une enveloppe dont les faces sont maintenues écartées au moyen d'entretoises. Le remplissage de l'enveloppe est réalisé au moyen d'un produit absorbant fixant le liquide ou exsudat. Les enveloppes sont perforées de manière à permettre la pénétration de l'exsudat et son absorption par l'intérieur de l'enveloppe. De nouveau, dans cette garniture, les coûts de fabrication sont élevés en raison de la complexité de l'ensemble qui nécessite des opérations de soudage et d'injection qui sont des opérations coûteuses.This lining takes the form of a cushion constituting an envelope whose faces are kept apart by means of spacers. The envelope is filled using an absorbent product which fixes the liquid or exudate. The envelopes are perforated so as to allow the exudate to penetrate and be absorbed by the interior of the envelope. Again, in this packing, the manufacturing costs are high because of the complexity of the assembly which requires welding and injection operations which are expensive operations.
Enfin, d'autres garnitures beaucoup plus simples, qui constituent des garnitures de base sont, par exemple, décrites dans le brevet FR-A-2.655.027. Dans ce cas, la garniture est constituée d'un recto réalisé en matériau imperméable perforé et d'un verso constitué d'un matériau absorbant, le recto étant destiné à être en contact avec le produit alimentaire, alors que le verso constituant la couche inférieure permet la récupération de l'exsudat. L'ensemble est solidarisé au fond de la barquette. Dans ce cas, il n'existe aucun moyen de séparation entre le recto et le verso et, de ce fait, l'exsudat est aisément remis en contact avec le produit alimentaire, ce qui peut entraîneur des problèmes bactériologiques importants en raison de contamination du produit.Finally, other much simpler fittings, which constitute basic fittings are, for example, described in patent FR-A-2,655,027. In this case, the filling consists of a front made of perforated waterproof material and a back made of an absorbent material, the front being intended to be in contact with the food product, while the back constituting the lower layer allows recovery of exudate. The whole is secured to the bottom of the tray. In this case, there is no means of separation between the front and back and, therefore, the exudate is easily brought back into contact with the food product, which can cause significant bacteriological problems due to contamination of the product.
Le but de la présente invention est donc de proposer une garniture palliant les inconvénients précités, cette garniture stratifiée monobloc non isolante étant bon marché, aisément recyclable, pouvant être fabriquée par des opérations simples de pressage et de collage et assurant de manière sûre la séparation du produit alimentaire et de l'exsudat.The object of the present invention is therefore to propose a filling which overcomes the aforementioned drawbacks, this non-insulating one-piece laminate lining being inexpensive, easily recyclable, being able to be produced by simple pressing and gluing operations and ensuring the separation of the food product and exudate.
L'invention concerne à cet effet une garniture stratifiée monobloc destinée à être placée dans, ou à constituer, le fond d'emballages alimentaires pour l'absorption des exsudats s 'écoulant du contenu, caractérisée en ce qu'elle comprend au moins trois couches superposées, à base de cellulose, munies de perforations disposées en regard, la couche supérieure en contact avec le produit alimentaire appelée recto étant réalisée en un matériau imperméable à l'eau et aux graisses, la couche inférieure dite verso étant constituée d'un matériau absorbant destiné à récupérer les exsudats s 'écoulant du produit alimentaire à travers les perforations de l'empilement, les couches inférieure et supérieure étant maintenues écartées l'une de l'autre d'une distance suffisante pour éviter tout contact de l'exsudat avec le produit alimentaire au moyen d'une couche intermédiaire formée de micro-cannelures de hauteur appropriée.To this end, the invention relates to a monobloc laminate lining intended to be placed in, or to constitute, the bottom of food packaging for the absorption of exudates flowing from the content, characterized in that it comprises at least three layers superimposed, cellulose-based, provided with perforations arranged facing each other, the upper layer in contact with the food product called the front being made of a material impermeable to water and grease, the lower layer called the back being made of a material absorbent intended to recover the exudates flowing from the food product through the perforations of the stack, the lower and upper layers being kept apart from each other by a sufficient distance to avoid any contact of the exudate with the food product by means of an intermediate layer formed of micro-grooves of appropriate height.
Selon une forme de réalisation préférée de l'invention, la couche supérieure est constituée d'un carton, la couche intermédiaire d'un carton ondulé, la couche inférieure d'un buvard.According to a preferred embodiment of the invention, the upper layer consists of a cardboard, the intermediate layer of a corrugated cardboard, the lower layer of a blotter.
L'invention concerne également un procédé de fabrication d'une garniture monobloc destinée notamment à être placée dans le fond d'emballages alimentaires, caractérisé en ce qu'on assemble la couche inférieure et la couche intermédiaire de ladite garniture par collage, on comprime au moyen d'un organe presseur la couche supérieure collée à la pile préalablement réalisée, on perfore de manière traversante la pile en différents endroits de sa surface, puis on dispose l'ensemble sur le fond d'un conditionnement approprié.The invention also relates to a method of manufacturing a one-piece liner intended in particular to be placed in the bottom of food packaging, characterized in that the lower layer and the intermediate layer of said liner are assembled by gluing, it is compressed with by means of a pressing member, the upper layer glued to the previously made stack, the stack is pierced through in various places on its surface, then the assembly is placed on the bottom of an appropriate package.
L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels
la figure 1 représente une vue de dessus d'une
garniture conforme à l'invention; et
la figure 2 représente une vue en coupe de la garniture
de la figure 1.The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the accompanying drawings in which
Figure 1 shows a top view of a
packing according to the invention; and
Figure 2 shows a sectional view of the packing
of figure 1.
La garniture stratifiée, objet de l'invention, est un complexe mono-matériau à base de cellulose entièrement recyclable et biodégradable. Cette garniture monobloc est destinée à être placée dans le fond des emballages alimentaires ou à en constituer le fond de manière à permettre l'absorption des exsudats s'écoulant du contenu de l'emballage. En raison de sa composition, cette garniture peut être en contact direct avec le produit tout en présentant un pouvoir élevé d'absorption et de rétention des liquides.The laminate lining, object of the invention, is a mono-material complex based on cellulose that is fully recyclable and biodegradable. This one-piece filling is intended to be placed in the bottom of food packaging or to constitute the bottom so as to allow the absorption of exudates flowing from the contents of the packaging. Due to its composition, this filling can be in direct contact with the product while having a high power of absorption and retention of liquids.
Conformément à la figure 2, cette garniture 1 comprend au moins trois couches 2, 3, 4 superposées, à base de cellulose, munies de perforations 5 traversantes.In accordance with FIG. 2, this lining 1 comprises at least three superposed layers 2, 3, 4, based on cellulose, provided with through holes 5.
La couche supérieure 2, en contact avec le produit alimentaire, appelée recto, est réalisée en un matériau imperméable à l'eau et aux graisses. En outre, ce matériau ingraissable et anti-adhérant est traité contre l'humidité.The upper layer 2, in contact with the food product, called the front, is made of a material impermeable to water and to grease. In addition, this greasy, non-stick material is treated against moisture.
Ainsi, à titre d'exemple, la face apparente ou recto de cette couche supérieure 2 pourra être réalisée en un carton couché multi-jet très fortement collé et ingraissable. L'autre face sera en pâte chimique blanchie traitée. Le grammage pourra varier en fonction de la rigidité désirée.Thus, by way of example, the visible or front face of this upper layer 2 can be produced from a coated multi-jet cardboard which is very strongly bonded and greasable. The other side will be treated bleached chemical pulp. The grammage may vary according to the desired rigidity.
La couche inférieure 4, dite verso, est constituée d'un matériau absorbant destiné à récupérer les exsudats s'écoulant du produit alimentaire à travers des perforations 5 de l'empilement. Cette couche inférieure 4 est de préférence formée par un papier buvard dont la caractéristique essentielle résidera dans sa capacité à absorber l'eau. A titre d'exemple, la valeur moyenne de l'absorption pourra être de l'ordre de 1610 g/m2. Dans certains cas, la couche inférieure 4 pourra être doublée d'un matériau formant fond à base toujours de cellulose de manière à constituer l'ensemble de la face formant fond du conditionnement.The lower layer 4, called the back, consists of an absorbent material intended to recover the exudates flowing from the food product through perforations 5 of the stack. This lower layer 4 is preferably formed by a blotting paper whose essential characteristic will reside in its capacity to absorb water. By way of example, the average value of the absorption may be of the order of 1610 g / m2. In certain cases, the lower layer 4 may be lined with a bottom-forming material always based on cellulose so as to constitute the whole of the bottom-forming face of the packaging.
La couche intermédiaire 3, qui maintient les couches supérieure 2 et inférieure 4 écartées l'une de l'autre d'une distance suffisante pour éviter tout contact de l'exsudat avec le produit alimentaire, est formée de micro ou petites cannelures de hauteur appropriée. Généralement, cette couche intermédiaire 3 est constituée d'un carton ondulé dont les ondulations sont constituées par des cannelures transversales en saillie vers le haut. En fonction du grammage et du coefficient d'onde choisis pour ce carton ondulé, on aura une hauteur et donc un écartement variable entre les couches inférieure 4 et supérieure 2. Ce choix de la couche intermédiaire interviendra également dans les propriétés finales de rigidité de la garniture.The intermediate layer 3, which keeps the upper 2 and lower 4 layers spaced from each other by a sufficient distance to avoid contact of the exudate with the food product, is formed of micro or small grooves of appropriate height . Generally, this intermediate layer 3 consists of corrugated cardboard, the corrugations of which consist of transverse grooves projecting upwards. Depending on the grammage and the wave coefficient chosen for this corrugated board, there will be a height and therefore a variable spacing between the lower 4 and upper 2 layers. This choice of the intermediate layer will also play a role in the final stiffness properties of the garnish.
Les perforations 5 sont, quant à elles, de forme et de dimension quelconques. Certaines de ces perforations, telles que des trous circulaires 6, peuvent servir à la fixation de la garniture dans le fond de l'emballage.The perforations 5 are, in turn, of any shape and size. Some of these perforations, such as circular holes 6, can be used to fix the gasket in the bottom of the packaging.
Pour la réalisation d'une telle garniture stratifiée monobloc 1, on procède généralement de la manière suivante. On superpose et on assemble par collage la couche inférieure 4 et la couche intermédiaire 3, on dispose et on presse la couche supérieure 2 encollée sur la face apparente de la couche intermédiaire de la pile préalablement réalisée et on perfore de manière traversante la pile sur au moins une partie de sa surface. For the production of such a one-piece laminate lining 1, the procedure is generally as follows. The lower layer 4 and the intermediate layer 3 are superimposed and assembled by bonding, the upper layer 2 glued is placed on and pressed on the visible face of the intermediate layer of the previously made pile and the pile is pierced through on minus part of its surface.
