Abstract

The present invention relates to a packaging tray, essentially for packing juice-releasing foodstuffs such as animal produce for example. This tray is characterised in that the perforations 3 of its bottom 2 have a size of the order of 1 mm<2> and are preferably from 350 to 400 per dm<2> in number, and the space between the two walls of the bottom of the tray, which contains an absorbent material 4, is calculated so that this absorbent material 4 is surrounded by a sufficient layer of air, even after reaching its maximum level of absorption, which therefore enables it to swell freely, resulting in an increase in its liquid-retaining capacity.

Description

La présente invention concerne une barquette de conditionnement pour l'empaquetage essentiellement de produits alimentaires libérant du jus, conçue pour permettre d'absorber et d'éliminer efficacement ce jus, souvent de couleur inappétissante. Cela est tout particulièrement important dans le cas d'emballaqes contenant des produits animaux. The present invention relates to a packaging tray for packaging primarily food products releasing juice, designed to allow the absorption and effective elimination of this juice, often of an unappetizing color. This is particularly important in the case of packages containing animal products.

Les barquettes existant jusqu'à présent fabriquées par moulaqe par compression de trois couches en sandwich ,à savoir: une couche supérieure perforée ,une couche inter médiaire absorbante et une couche inférieure qui, tout comme ia couche supérieure, ne doit être que peu ou pas affectée par le contenu liquide des denrées alimentaires. Cette formule s'est toutefois révéiée insuffisamment en mesure d'absorber ie liquide s'écoulant, dont ia couleur transparait en outre de manière inesthétique à travers les perforations. The trays existing until now manufactured by compression molding of three sandwich layers, namely: a perforated upper layer, an absorbent middle layer and a lower layer which, like the upper layer, should be little or no affected by the liquid content of food. This formulation, however, was found to be insufficiently capable of absorbing the flowing liquid, the color of which furthermore showed unsightly through the perforations.

La barquette suivant l'invention permet par contre d'éliminer totalement ces inconvénients. Cette barquette comprend un double fond en matière plastique imperméable aux liquides, dont celui qui est en contact avec les produits alimentaires comporte des perforations de l'ordre de 1 mm2, de préférence au nombre de 350-400 par dm2. Par ailleurs, i'espace compris entre les deux parois du fond -de la bar omette, qui contient un matériau absorbant,est calculé de telle sorte que ce matériau absorbant soit toujours entouré d'une couche d'air suffisante, même après avoir atteint son taux maximal d'absorption, ce qui lui permet donc de gonfler librement, avec pour résultat une augmentation de sa capa- cité de rétention de liquide.Cette même barquette est également caractérisée par le fait que la surface perforée sur laquelle reposent les denrées alimentaires, est lisse et que son fond extérieur comporte plusieurs creux séparés par des cannelures transversales en saillie vers le haut, le rêle des cannelures étant en premier lieu de servir de support au matériau absorbant et celui des creux de recueillir l'exce- dent de liquide non absorbé. Par cette formule, mise au point à la suite de longs essais avec différents types de produits alimentaires,il a été possibie de réaliser un em balivage à ia fois hygiénique et esthétique,parfaitement fonctionnel pour ce qui est d'aborsber le jus des denrées caractérisées par un abondant écouiement. The tray according to the invention on the other hand makes it possible to completely eliminate these drawbacks. This tray comprises a double bottom made of plastic material impermeable to liquids, of which that which is in contact with the food products has perforations of the order of 1 mm 2, preferably 350-400 per dm 2. Furthermore, the space between the two walls of the bottom of the bar omette, which contains an absorbent material, is calculated so that this absorbent material is always surrounded by a sufficient layer of air, even after having reached its maximum absorption rate, which therefore allows it to swell freely, resulting in an increase in its liquid retention capacity. This same tray is also characterized by the fact that the perforated surface on which the foodstuffs rest , is smooth and that its outer bottom has several hollows separated by transverse grooves projecting upwards, the role of the grooves being primarily to serve as a support for the absorbent material and that of the hollows to collect the excess liquid not absorbed. By this formula, developed following long tests with different types of food products, it was possible to achieve a balivage ia both hygienic and aesthetic, perfectly functional in terms of absorbing the juice of the characterized food. by an abundant discharge.

On décrira ci-après,à titre d'exemple non limitatif, une forme d'exécution de la présente invention,en référence au dessin annexé sur lequel
La figure 1 est une vue en perspective du dessus d'une barquette avec un arrachement à l'endroit de l'un de ses angles.An embodiment of the present invention will be described below, by way of nonlimiting example, with reference to the appended drawing in which
FIG. 1 is a perspective view from above of a tray with a cutaway at the location of one of its angles.

La figure 2 est une vue en perspective éclate de la barquette. Figure 2 is an exploded perspective view of the tray.

Les figures 3a et 3b sont des vues en coupe de la barquette, respectivement selon les deux axes b-bl et a-al indiqués sur la figure 2. Figures 3a and 3b are sectional views of the tray, respectively along the two axes b-bl and a-al indicated in Figure 2.

Les figures 4a et 4b sont des vues en coupe de ia barquette semblables è celles des figures 3a et 3b mais avec en plus son fond intérieur perforé et la couche de matériau absorbant. Figures 4a and 4b are sectional views of the tray similar to those of Figures 3a and 3b but with in addition its perforated inner bottom and the layer of absorbent material.

Sur le dessin la barquette est désignée par 1, les creux du fond par 6 et les cannelures en saillie vers ie haut par 5. Ces cannelures servent en même temps de support au matériau absorbant 4 et de séparations aux creux 6 prévus pour recueillir dans les cas extrêmes l'excédent de liquide rejeté par les denrées alimentaire,celles-ci reposant sur le fond lisse 2, muni d'un grand nombre de fines perforations 3, ce fond 2 ayant une couche superficielle dure agréée pour son utilisation au contact d'aiiments. Les points de fixation du fond intérieur 2,constitué par une plaque amovible sont désignés par 7,ce fond étant collé, au moyen de colle fusible, sur le fond extérieur de la barquette 1. A titre d'exemple de matière plastique pour la barquette l,il est possi-bie d'envisager du polystyrène expansé, et pour le fond extérieur 2 du chlorure de polyvinyle (PVC). Un matériau absorbant approprié peut être par ailleurs constitué de plusieurs épaisseurs de papier h usage domestique, de préférence au nombre de 15, ou plusieurs feuilles de cellulose. In the drawing, the tray is designated by 1, the hollows in the bottom by 6 and the grooves projecting upwards by 5. These grooves serve at the same time as a support for the absorbent material 4 and as separations for the hollows 6 provided to collect in the extreme cases the excess liquid rejected by the foodstuffs, the latter resting on the smooth bottom 2, provided with a large number of fine perforations 3, this bottom 2 having a hard surface layer approved for its use in contact with love. The fixing points of the inner bottom 2, consisting of a removable plate are designated by 7, this bottom being glued, by means of hot-melt adhesive, to the outer bottom of the tray 1. By way of example of plastic material for the tray l, it is possi-bie to consider expanded polystyrene, and for the outer bottom 2 of polyvinyl chloride (PVC). A suitable absorbent material may furthermore consist of several layers of household paper, preferably 15 in number, or several sheets of cellulose.
