Abstract

A support for food products includes a cardboard support on which an impermeable layer of plastic material is applied. The layer of plastic material can be of the polyethylene type, for example. The impermeable layer has perforations that provides for the absorption of exudate and any other liquid from food product support. The support advantageously can form the bottom of a liquid-tight boat-shaped tray for packaging, storing and/or displaying of meat products, such as poultry of slices of beef, for example.

Description

La présente invention concerne le domaine de l'emballage ; elle concerne plus particulièrement un support de produit alimentaire, du genre barquette en carton à coins étanches, par exemple, destiné notamment à l'emballage de produit carné, à son conditionnement, stockage ou présentation à la vente. Ce support en carton est du type muni d'une couche imperméable de contact, en forme de pellicule genre polyéthylène alimentaire par exemple. La nature de cette pellicule assure l'imperméabilisation du conditionnement ; elle renforce avantageusement l'étanchéité, notamment au niveau des angles, pour éviter que les liquides ou exsudats provenant du produit conditionné ne souillent la périphérie de l'emballage et son environnement extérieur direct.The present invention relates to the field of packaging; it relates more particularly to a food product support, of the cardboard tray type with tight corners, for example, intended in particular for packaging meat product, for its packaging, storage or presentation for sale. This cardboard support is of the type provided with an impermeable contact layer, in the form of a film such as food polyethylene for example. The nature of this film ensures the waterproofing of the packaging; it advantageously strengthens the seal, especially at the corners, to prevent liquids or exudates from the packaged product from contaminating the periphery of the packaging and its direct external environment.

En contrepartie, ce renfort d'étanchéité limite la dissipation des exsudats liquides du produit. Ces liquides biologiques stagnent dans le fond de la barquette et favorisent le développement bactérien. Cet aspect particulier limite le temps de conservation des produits et peut avoir une influence sur leurs qualités gustatives.In return, this sealing reinforcement limits the dissipation of liquid exudates from the product. These biological liquids stagnate in the bottom of the tray and promote bacterial development. This particular aspect limits the shelf life of products and can have an influence on their taste qualities.

Pour pallier à cet inconvénient, il est courant de positionner sur le fond une feuille intercalaire, libre, en matériau absorbant du type cellulose, éponge ou luffa, compatible et adaptée au produit conditionné. Le matériau absorbant disposé entre le fond-support et le produit, réceptionne les exsudats libérés ; il les disperse et les éponge rapidement pour limiter les risques de débordement à l'extérieur.To overcome this drawback, it is common to position on the bottom an intermediate sheet, free, of absorbent material of the cellulose, sponge or loofah type, compatible and suitable for the packaged product. The absorbent material disposed between the support base and the product, receives the released exudates; it disperses and sponges them quickly to limit the risk of overflowing outside.

Cette technique est relativement efficace mais elle nécessite une opération préalable de positionnement de la feuille absorbante sur le support, avant de conditionner le produit. Cette opération génère un coût matière important sans résoudre les problèmes de développement bactériologiques liés au contact permanent entre la cellulose, les exsudats et le produit.This technique is relatively effective but it requires a prior operation of positioning the absorbent sheet on the support, before packaging the product. This operation generates a significant material cost without resolving the bacteriological development problems linked to the permanent contact between the cellulose, the exudates and the product.

Le document GB-A-1 168 925 décrit une barquette de conditionnement dont le fond est constitué d'un complexe de trois couches superposées : une couche supérieure de contact en matériau imperméable genre polystyrène munie de perforations et de canaux de drainage, une couche intermédiaire absorbante type papier buvard, et une couche inférieure également en polystyrène. Les perforations de la couche de contact supérieure permettent l'absorption des liquides ou exsudats par la couche intermédiaire absorbante. Cette structure de support s'avère relativement compliquée à fabriquer et son coût de revient est relativement important.Document GB-A-1 168 925 describes a packaging tray, the bottom of which consists of a complex of three superimposed layers: an upper contact layer of impermeable polystyrene-like material provided with perforations and drainage channels, an intermediate layer absorbent blotting paper type, and a lower layer also made of polystyrene. The perforations in the upper contact layer allow the absorption of liquids or exudates by the absorbent intermediate layer. This support structure is relatively complicated to manufacture and its cost is relatively high.

La présente invention propose un support de produit alimentaire, de structure très simple et peu onéreuse, qui permet de remédier aux inconvénients précités.The present invention provides a food product support, of very simple and inexpensive structure, which overcomes the aforementioned drawbacks.

Ce support particulier est préparé en usine et on peut l'utiliser tel quel, sans apport d'éléments complémentaires. Sa surface supérieure, en contact avec le produit conditionné, répond aux normes d'hygiène en vigueur ; elle est en outre adaptée pour assurer l'absorption des exsudats liquides provenant du produit afin de limiter la propension des bactéries a se développer.This particular support is prepared in the factory and can be used as it is, without any additional elements. Its upper surface, in contact with the packaged product, meets current hygiene standards; it is also suitable for ensuring the absorption of liquid exudates from the product in order to limit the propensity of bacteria to grow.

Le support de produit alimentaire selon l'invention est du type constitué d'un complexe de plusieurs couches superposées de matériaux, la couche supérieure de contact étant munie de perforations qui permettent l'absorption des exsudats et autres liquides par une couche inférieure. Ce support est caractérisé par le fait qu'il est constitué d'un complexe de deux couches superposées de matériaux, la première couche se présentant sous la forme d'un plateau de carton et la seconde étant constituée d'une couche imperméable de contact ; le complexe bi-couches comporte des perforations qui traversent complètement la couche imperméable et qui pénètrent partiellement dans l'épaisseur du plateau de carton pour permettre l'absorption des exsudats et autres par le plateau de carton lui-même. Les exsudats libérés peuvent ainsi se disperser par capillarité dans son épaisseur.The food product support according to the invention is of the type consisting of a complex of several superimposed layers of materials, the upper contact layer being provided with perforations which allow the absorption of exudates and other liquids by a lower layer. This support is characterized by the fact that it consists of a complex of two superimposed layers of materials, the first layer being in the form of a cardboard tray and the second consisting of an impermeable contact layer; the two-layer complex has perforations which completely pass through the impermeable layer and which partially penetrate the thickness of the cardboard tray to allow absorption of exudates and the like by the cardboard tray itself. The released exudates can thus disperse by capillarity in its thickness.

La couche imperméable en matériau plastique assure un contact hygiénique entre le support et le produit conditionné ; en outre, elle évite le collage des fibres de carton sur le produit emballé. De plus, on utilise les qualités de porosité du matériau qui soutient cette couche de contact pour absorber les exsudats ou liquides qui proviennent du produit conditionné.The impermeable layer of plastic material ensures hygienic contact between the support and the packaged product; in addition, it prevents the sticking of cardboard fibers on the packaged product. In addition, the porosity qualities of the material which supports this contact layer are used to absorb the exudates or liquids which come from the packaged product.

Les perforations peuvent être réalisées par une opération d'emboutissage, de cisaillement ou de poinçonnement de la couche imperméable de contact sur le carton. La profondeur de ces perforations est de préférence sensiblement égale à la moitié de l'épaisseur du complexe carton-couche imperméable.The perforations can be carried out by a stamping, shearing or punching operation of the waterproof contact layer on the cardboard. The depth of these perforations is preferably substantially equal to half the thickness of the cardboard-waterproof layer complex.

Les poinçons utilisés sont adaptés, dans leur forme et leur positionnement, pour réaliser des perforations aptes à obtenir le meilleur compromis entre une bonne absorption des exsudats du produit, la présence d une surface maximale de couche imperméable sur laquelle va venir reposer le produit conditionné et le maintien d'une bonne rigidité du plateau support.The punches used are adapted, in their shape and their positioning, to produce perforations capable of obtaining the best compromise between a good absorption of the exudates of the product, the presence of a maximum surface of impermeable layer on which goes come and rest the conditioned product and maintain good rigidity of the support plate.

Les perforations peuvent être réalisées sur plusieurs lignes, au niveau des bordures du plateau support.The perforations can be made on several lines, at the edges of the support plate.

Selon une disposition particulière, le support perforé constitue le fond d'une barquette étanche. Ainsi, outre ses qualités hygiéniques, la couche imperméable de contact complète l'étanchéité au niveau des angles du conditionnement. Cette étanchéité assure le cloisonnement des liquides ou exsudats dans l'emballage, lesquels exsudats ou liquides seront ensuite absorbés progressivement par le carton support, grâce à la présence des perforations.According to a particular arrangement, the perforated support constitutes the bottom of a sealed tray. Thus, in addition to its hygienic qualities, the waterproof contact layer completes the seal at the corners of the packaging. This seal ensures the partitioning of liquids or exudates in the packaging, which exudates or liquids will then be gradually absorbed by the cardboard support, thanks to the presence of the perforations.

Mais l'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'un mode de réalisation particulier, donné à titre d'exemple et représenté sur les dessins annexés dans lesquels :

  • la figure 1 est une vue de dessus d'un support selon l'invention, intégré dans un flan de carton destiné à la réalisation d'une barquette étanche ; les contours du flan sont représentés en traits mixtes fins ;
  • la figure 2 est une vue en perspective de la barquette mise en volume, sur le fond perforé de laquelle est positionné le produit à conditionner;
  • la figure 3 est une vue agrandie, en coupe transversale, montrant le support perforé selon l'invention, constitué d'une feuille de carton recouverte d'une couche imperméable de contact en matériau plastique.
However, the invention will be further illustrated, without being in any way limited, by the following description of a particular embodiment, given by way of example and represented in the appended drawings in which:
  • Figure 1 is a top view of a support according to the invention, integrated in a cardboard blank for the production of a sealed container; the contours of the blank are shown in thin dashed lines;
  • Figure 2 is a perspective view of the tray set in volume, on the perforated bottom of which is positioned the product to be packaged;
  • Figure 3 is an enlarged view, in cross section, showing the perforated support according to the invention, consisting of a cardboard sheet covered with an impermeable contact layer of plastic material.

Comme on peut le voir sur les figures, le support de produit alimentaire selon l'invention est constitué d'un plateau 1 en carton dont la forme et les dimensions sont adaptées au produit qui doit être conditionné. Le carton utilisé peut avoir une épaisseur de l'ordre de 0,5 à 2 mm par exemple.As can be seen in the figures, the food product support according to the invention consists of a cardboard tray 1 whose shape and dimensions are adapted to the product to be packaged. The cardboard used can have a thickness of the order of 0.5 to 2 mm for example.

La face supérieure du plateau 1, sur laquelle va venir reposer le produit conditionné, est recouverte d'une couche imperméable 2 qui offre une surface de contact propre et hygiénique dont les caractéristiques répondent aux normes alimentaires en vigueur.The upper face of the plate 1, on which the conditioned product will come to rest, is covered with an impermeable layer 2 which provides a clean and hygienic contact surface whose characteristics meet the food standards in force.

La couche imperméable 2 est appliquée et/ou solidarisée au plateau 1 de carton par tout moyen classique du domaine technique. Elle peut être réalisée par extrusion d'une pellicule de contact en matériau du genre polyéthylène alimentaire ; elle peut également être obtenue par tout autre traitement imperméabilisant, du type inclusion dans la masse, par exemple, en vue de bloquer les fibres en surface et éviter l'arrachage intempestif, notamment lors de l'enlèvement du produit conditionné.The waterproof layer 2 is applied and / or secured to the cardboard tray 1 by any conventional means of the technical field. It can be carried out by extrusion of a contact film of material of the food polyethylene type; it can also be obtained by any other waterproofing treatment, of the type included in the mass, for example, with a view to blocking the fibers on the surface and preventing untimely tearing, in particular during the removal of the packaged product.

Les figures 1 à 3 montrent que la couche imperméable 2 comporte un ensemble d'orifices, d'ouvertures ou de perforations 3 dont la forme et la disposition sont adaptées notamment pour assurer une absorption optimale de l'humidité ou des liquides par le plateau 1 de carton.Figures 1 to 3 show that the waterproof layer 2 comprises a set of orifices, openings or perforations 3 whose shape and arrangement are adapted in particular to ensure optimal absorption of moisture or liquids by the tray 1 of cardboard.

Ces perforations 3 sont réalisées de préférence après avoir appliqué le couche imperméable 2 sur le support rigide 1.
La perforation du complexe couche imperméable 2-plateau 1 est réalisé en usine, lors de la fabrication du support de produit alimentaire. Cette opération peut par exemple être réalisée en bout de chaîne, par cisaillement, au moyen d'un ou de plusieurs cylindres munis de poinçons adaptés, ou par emboutissage, au moyen de filets coupeurs.
Tel qu'on l'a représenté sur la figure 3, la profondeur x des perforations 3 est comprise entre l'épaisseur a de la couche imperméable 2 et l'épaisseur b du complexe plateau 1-couche 2 ; cette épaisseur x est de préférence sensiblement égale à la moitié de l'épaisseur b dudit complexe carton-couche imperméable pour assurer une pénétration des liquides au coeur du carton et permettre une absorption maximale des liquides ou exsudats libérés.These perforations 3 are preferably made after applying the impermeable layer 2 to the rigid support 1.
The perforation of the waterproof layer 2-tray 1 complex is carried out in the factory, during the manufacture of the food product support. This operation can for example be carried out at the end of the chain, by shearing, by means of one or more cylinders provided with suitable punches, or by stamping, by means of cutting threads.
As shown in FIG. 3, the depth x of the perforations 3 is between the thickness a of the impermeable layer 2 and the thickness b of the plate 1-layer 2 complex; this thickness x is preferably substantially equal to half the thickness b of said cardboard-waterproof layer complex to ensure penetration of liquids into the heart of the cardboard and allow maximum absorption of the liquids or exudates released.

Les poinçons peuvent être constitués de pointes, de cylindres, de filets sinusoïdaux ou encore, tel que représenté sur les figures annexés, de lames qui définissent des entailles allongées.The punches can consist of points, cylinders, sinusoidal threads or, as shown in the appended figures, blades which define elongated notches.

Les perforations 3 sont réparties sur la surface du support de produit alimentaire de façon à assurer l'absorption des exsudats ou liquides, en quelque endroit qu'ils puissent se déposer, et également pour conserver une tenue et rigidité correctes du plateau support 1.The perforations 3 are distributed over the surface of the food product support so as to ensure the absorption of exudates or liquids, in some place that they can be deposited, and also to maintain the correct strength and rigidity of the support plate 1.

A titre d'exemple, les perforations 3 peuvent être disposées en lignes, sur les bordures du plateau de carton 1, au niveau des limites périphériques du produit conditionné.By way of example, the perforations 3 can be arranged in lines, on the edges of the cardboard tray 1, at the peripheral limits of the packaged product.

Selon une disposition préférentielle, le plateau de carton 1 peut constituer le fond d'un emballage en forme de barquette 4 pour le conditionnement d'un produit 5 représenté en pointillés sur la figure 2. Le plateau 1 a, dans ce cas, une forme générale rectangulaire, et il est bordé de quatre côtés latéraux 6, 7, 8 et 9, reliés deux à deux par des soufflets d'étanchéité 10.According to a preferred arrangement, the cardboard tray 1 can constitute the bottom of a packaging in the form of a tray 4 for the packaging of a product 5 shown in dotted lines in FIG. 2. The tray 1 has, in this case, a shape generally rectangular, and it is bordered by four lateral sides 6, 7, 8 and 9, connected two by two by sealing bellows 10.

Les perforations 3 réalisées dans le fond-support de l'emballage peuvent être réalisées avant ou après les opérations de découpe et de rainurage, mais, en règle générale, avant la mise en volume de la barquette.The perforations 3 produced in the bottom support of the packaging can be carried out before or after the cutting and grooving operations, but, as a general rule, before the tray is placed in volume.

On remarque, sur la figure 1 qui montre le flan de carton, à plat, que les lignes de perforations allongées 3 suivent les quatre bordures du plateau 1. L'opération de perforation peut être obtenue en une seule passe sur un dispositif perforateur unique ; il est également possible de prévoir une pluralité de dispositifs juxtaposés munis de poinçons perforateurs adaptés.Note, in Figure 1 which shows the cardboard blank, flat, that the elongated perforation lines 3 follow the four edges of the tray 1. The perforation operation can be obtained in a single pass on a single perforator device; it is also possible to provide a plurality of juxtaposed devices provided with suitable punch punches.

Lorsque le flan de carton est mis en volume, la barquette 4 est directement utilisable pour le conditionnement de tout produit alimentaire présentant une certaine humidité de surface ou susceptible de libérer des liquides biologiques ou exsudats.
Le support de produit alimentaire selon l'invention définit une surface plane d'accueil de qualité alimentaire ; cette surface est munie d'une pluralité de perforations 3 réalisées dans la couche imperméable 2, qui vont permettre l'absorption des liquides ou de l'humidité par le carton. La surface occupée par les perforations 3 n'est pas très importante et n'altère pas l'hygiène du support. La densité des perforations est choisie et adaptée en fonction du produit conditionné pour éviter le contact prolongé entre ledit produit et les liquides qu'il génère, tout en limitant l'altération de l'environnement immédiat de l'emballage.When the cardboard blank is set in volume, the tray 4 is directly usable for the packaging of any food product having a certain surface humidity or capable of releasing biological liquids or exudates.
The food product support according to the invention defines a flat reception surface for food quality; this surface is provided with a plurality of perforations 3 made in the impermeable layer 2, which will allow the absorption of liquids or moisture by the cardboard. The surface occupied by the perforations 3 is not very large and does not affect the hygiene of the support. The density of the perforations is chosen and adapted according to the product packaged to avoid prolonged contact between said product and the liquids it generates, while limiting the alteration of the immediate environment of the packaging.
