Definitions

  • a package tray for liquid-containing food products such as meat
  • the invention concerns a package tray for liquid-contain ⁇ ing food products, such as meat, said package tray being made of e.g. sheeting and having a storage space which - seen in the normal position of rest of the tray - is de ⁇ fined downwardly by a bottom and by upright side walls along the sides, said bottom being provided with a plura ⁇ lity of ridges having upwardly converging walls.
  • Today such trays are used in very large numbers for the distribution of ready-for-sale food products, which are placed in the trays, which are generally then coated with a thin, transparent plastics sheet permitting the custo ⁇ mers to inspect the respective article.
  • the food products can hereby be displayed freely accessibly in refrigerated display cases in retail outlets, from which the customers, according to the self-service principle, can then select and pick up the article which appeals most to them.
  • GB patent specification 974 180 discloses a thin walled tray of thermoplastics having longitudinal and transverse ribs in the bottom. The distance of the ribs from the opening of the tray decreases with the distance from the side edges, resulting in the formation of a fall toward these in the spaces between the ribs. This entails that the meat juices are conveyed to the edge area of the tray where the juice is clearly visible from the outside.
  • GB patent specification 1 527 212 describes a package tray for storing sausages.
  • the tray has a plane bottom provided with rows of uniform, pyramidal projec ⁇ tions which are so dimensioned that a sausage can be ac ⁇ commodated between two rows.
  • the purpose of this structure is to obtain air circulation around the sausages, but the plane bottom does not enable possible meat juice to be drained off to a non-visible location, and the great dis ⁇ tance between the projections does not ensure separation between a possible meat article and the meat juice.
  • GB patent specification 2 003 836 discloses a tray for perishable food products exuding juices.
  • the bottom con- sists of a plane face whose center has a recessed collec ⁇ tion area. Further, the bottom is formed with a plurality of grooves extending inwardly from the edges to the col ⁇ lection area.
  • a hygroscopic material may be placed in the collection area for absorbing the juices. Owing to the relatively large, plane faces between the grooves some of the meat juice cannot be effectively con ⁇ veyed down to the collection are owing to the capillary effect.
  • GB patent specification 2 059 920 describes a tray whose bottom is provided with a system of ribs and grooves serv ⁇ ing to convey exuding liquids from the packaged article to grooves or areas along the side edges where the juices are readily visible to the customers.
  • This tray has a rela ⁇ tively sturdy construction and is intended for the trans ⁇ port of meat pies and cannot therefore be regarded as a package tray proper.
  • DK 155 789 discloses an open box of relatively great thickness.
  • the bottom is formed with a plurality of up ⁇ wardly extending knobs having a plane surface, which col ⁇ lectively form a face sloping downwards toward the center of the bottom, while the actual bottom forms a face slop ⁇ ing downwards toward the side walls.
  • the side walls are moreover formed with holes for discharge of liquid, and the box is particularly intended for the transport of fish.
  • the plane top sides of the knobs form a relatively large contact area with the articles.
  • the object of the invention is to provide a package tray of the type mentioned in the opening paragraph, which can be manufactured at small costs and in a simple structure, and which is capable of effectively separating the pack ⁇ aged food product from exuding juices better than known before and conceal them during storage.
  • the package tray may have a skirt extending downwardly on the outer side of the side walls from their upper rim.
  • the skirt When the height of the skirt is greater than that of the side walls, the skirt then serves as a foot on which the tray can stand in the position of rest.
  • the tray With a suitable selection of the height of the skirt the tray can rest on a horizontal base with the central area in addition to the foot, when the tray is filled and is in the position of rest.
  • the ridges may have the shape of cones or truncated cones with rounded tops, and to avoid perforation of the surface of the packaged food product by these tops, the area of each top may be determined by the surface pressure between the top and the food product part which rests on the top in use being slightly smaller than the pressure which the surface of the food product can resist without being broken.
  • fig. la is a perspective view of a first embodiment of the package tray of the invention.
  • fig. lb is a top view of the same
  • fig. lc is a sectional view of the same
  • fig. 2a is a top view of a second embodiment of the pack ⁇ age tray of the invention.
  • fig. 2b is a top view of the same
  • fig. 3a is a perspective view of a third embodiment of the package tray of the invention.
  • fig. 3b is a top view of the same
  • fig. 3c is a longitudinal sectional view of the tray
  • fig. 3d is a transverse sectional view of the tray
  • fig. 4a is a top view of a fourth embodiment of the pack ⁇ age tray of the invention.
  • fig. 4b is a longitudinal sectional view of the tray
  • fig. 4c is a transverse sectional view of the tray
  • fig. 5a is a view of a fifth embodiment of the package tray of the invention in an unloaded state
  • fig. 5b is a view of the same, but loaded by a food pro ⁇ duct.
  • the first embodiment of the pack ⁇ age tray shown in figs, la-lc is made of vacuum-formed thermoplastics sheeting which may optionally consist of a laminate.
  • the tray is equilateral and has side walls 10 extending from a base 11 upwardly to a bent rim 12.
  • a skirt 14 extends downwardly from this rim 12 over a distance which is slightly longer than the height of the side walls.
  • the lower edge 15 of the skirt will hereby serve as a foot for the tray.
  • the edge of the skirt may be cut clean or, as shown, be provided with a rela ⁇ tively small, outwardly directed flap for stiffening the shell and forming a suitable supporting face for the pack ⁇ age tray.
  • a plurality of upwardly directed pyramids 17 are provided along the entire base, each of said pyramids having a square foot 18 and a relatively pointed top 19. These tops are arranged equidistantly and are so pointed as to form the least possible area of contact with the food product which they carry. However, the tops may not be so pointed as to damage the food product by perforating its surface. This is obtained by dimensioning each top with an area which is just so large that the surface pressure between the respective top and the food product will be slightly smaller than the pressure which the surface of the food product can resist without being perforated. As will be seen from fig. lc, the height of the pyramids increases successively with the distance from the side walls 10.
  • the tray is empty in the shown case.
  • a face containing the tops 19 slopes downwards toward a central point 2 in the tray, while the actual base slopes down ⁇ wards toward this center.
  • the underside 4 of the central point rests against a plane support 6 together with the edge 15.
  • the package tray may be constructed such that in the unloaded state of the tray the underside 4 is raised slightly, e.g. 1-2 mm, with respect to the embodi ⁇ ment shown in fig. lc.
  • the weight of these presses the underside 4 down to engage the support 6 and thereby transfers the weight to this support together with the edge 15.
  • the ridges 20 are conical with rounded tops 21.
  • the structure otherwise corresponds to the first embodiment shown in figs, la, b, c, each cone having a foot 22, and the height of the tops 21 increasing successively with the distance from the side walls to a central point 2.
  • the actual base forms a face 23 which may be continuous or divided into separate areas when the feet 22 of the cones adjoin each other. This em ⁇ bodiment has the advantage that it is easy to manufacture, and that with respect to the first embodiment there is more space for collection of liquid between the cones around the central point 2.
  • Rectangular package trays are preferred in many cases to the above-mentioned rectangular package trays.
  • Figs. 3a-3d thus show a rectangular package tray which corresponds to the tray shown in figs, la-lc, except that its sides do not have the same length.
  • figs. 4a-4c show a rectangular package tray which corresponds to the package tray shown in figs. 2a-2b. Since the rectangular trays do not have sides of the same length, the bases 30 and 40, respectively, may have a central area 3 proper instead of a central point in the bases, said central area having a plurality of ridges 31, 41 of the same height in the longitudinal direction of the tray. Each row extends transversely to the longitudinal direction, and merely one such row is provided in a specific variation of this embo ⁇ diment.
  • the base 50 of the tray is formed such that in an unloaded state (fig. 5a) it is plane and has ridges 52 whose height increases successive ⁇ sively toward the center 2.
  • the ridges 52 are arranged at such a great mutual distance that the spaces between them form a reservoir having a considerably capacity for col ⁇ lecting exuding liquid from the packaged liquid.
  • this product 54 is now placed on the ridges 52.
  • the weight of the product 54 forces the cen ⁇ ter 2 of the tray down to contact the support 6.
  • a face containing the tops of the ridges 52 is substantially plane, and the base forms a large reservoir centrally below the food product to receive exuding liquid, which cannot contact the food product and cannot be seen from the outside.
  • All of the embodiments of the package tray of the inven ⁇ tion described above have the advantage that exuding liquid from the packaged food product is collected in a well-defined central area where the liquid is not visible form the outside, and which can easily accommodate so much liquid that this is kept spaced from the product with cer ⁇ tainty when the tray is in a position of rest.
  • the tray is made of relatively thin sheeting, it is ex- tremely stable because of its structure and does not tend to tilt when it is filled with products.
  • the trays are moreover stackable.
  • the ridges just serve as examples, and the ridges may thus have other geo ⁇ metrical shapes, e.g. truncated pyramids having a hexa ⁇ gonal foot or truncated cones.
  • the distance between the tops of the ridges may vary in a given section through the base.
  • the distance between the tops may be smallest closest to the side walls and increase toward the central area of the base.
  • the number of tops per unit of area must be so large that the product resting on the tops does not hang so far down as to contact the liquid in the base.
  • the central point or the central area having the greatest ridge height does not necessarily have to be in the center of the tray if the shape of the food product, or other conditions, should make it expedient to displace this point or area with respect to the geometrical center of the tray.

Abstract

Un bac d'emballage sert à stocker des produits alimentaires contenant un liquide, tel que la viande. Le bac est composé, par exemple, d'un matériau en feuille et comprend un espace de rangement qui, lorsque le bac est dans sa position normale, est défini au bas par une base (11), et par des parois latérales verticales (10) le long des côtés. La base est pourvue d'une multiplicité de nervures (17) dont les parois convergent vers le haut. Dans une zone de la base (11), située entre les parois latérales (10) et une région centrale prédéterminée (2), la hauteur des nervures (17) augmente progressivement avec la distance les séparant des parois latérales (10), et la base (11), dans cette zone, descend vers le bas et vers l'intérieur jusqu'à la région centrale (2). Du liquide exsudé par la viande, tel que du sang et des fluides provenant des tissus, s'écoule vers cette région centrale (2), où il sera dissimulé des clients. Le liquide recueilli dans la région centrale (2) est séparé des produits emballés par l'intermédiaire des nervures (17) se trouvant dans cette région. Ainsi, un produit alimentaire emballé, exsudant du liquide, peut être maintenu à sec dans le bac d'emballage même pendant une longue période de stockage, par exemple dans une vitrine de présentation réfrigérée, le produit préservant ainsi un aspect hygiénique et esthétiquement plaisant pour les clients.
