Definitions

  • the present invention relates to the field of containers for packaging, storage and transport of foodstuffs, and in particular containers and packages for products requiring drainage or absorption of their liquids.
  • the container with a floor having triangular cells has not been disclosed in the prior art.
  • the known foodstuff packages which are mainly used for packaging and selling meat, poultry, fish and similar products, usually consist of a disk, in which the product is positioned and which is covered with a transparent, outer, plastic housing.
  • this package such as disks comprising an absorbent material, usually in the form of a sublayer, between the product and the disk, in order to retain liquids.
  • These sub-layers are typically produced from absorbent paper pulp, while externally they have a coating with flexible polyethylene films, so that the pieces of paper pulp that come in contact with the foodstuff do not stick thereto.
  • disks incorporating the adsorbent surface such as the disk presented in US5709897 , or are focused on the improvement of the adsorbent surfaces, as with the invention described in WO2004099009 .
  • disks as the one proposed in WO2007008874 which apart from the individual adsorbent sublayer they also have a grid, on which the foodstuff is placed in order that it is elevated in relation to the bottom of the disk and not come in direct contact with the liquids.
  • a further disadvantage of the disks with the adsorbent sublayers is the increased cost, which inevitable is conveyed to the final consumer, since he needs to obtain the specific laminated paper sublayer. Given that the paper sublayer is frequently glued to the bottom of the container, further issues emerge, since for the positioning and gluing additional expenses are required, either for the materials, and for the necessary work, even for the consumed energy.
  • a further object of the present invention is to provide the proposed container with a bottom having triangular cells, which is manufactured from the same material constituting the container, poly(ethylene terephthalate), also known as PET.
  • PET is a fully recyclable material, does not have toxic ingredients, is fully safe for use in food packaging. Also it has a high mechanical strength with a respective low weight, and it has a low permeability to oxygen, carbon dioxide and water, keeping the packaged products in optimal condition for a large time period. Finally, it should not be ignored that due to the full transparency of the material it provides cleanness and an optimal visual contact with the packaged products.
  • a further object of the present invention is to provide a container with a bottom having triangular cells, which retains the liquids in the cells, due to the capillary force phenomenon.
  • a further object of the invention in order to make the container with a bottom having triangular cells of the present invention useful, is the formation of triangular cells with acute dihedral angles, which can enclose the liquids even better, due to the surface tension of the liquids being increased at acute recesses.
  • a further object of the invention is to provide a container with a bottom having triangular cells, which exploits the shape of the cells, occupying the maximum portion of the bottom area, due to the nesting of the triangles between them.
  • Another object of the invention is to provide a container with a bottom having triangular cells, which has a better liquid retention in the cells than any other currently available container with or without a sublayer.
  • An advantage of the present invention is also the manufacturing of a container with a bottom having triangular cells, which presents a reduced production cost, due to the elimination of the paper sublayer, while in parallel the cost is further reduced by the elimination of the positioning and bonding of the sublayer to the bottom of the container.
  • Another advantage of the present invention is its easy recycling, since it is manufactured exclusively from PET, which is fully recyclable.
  • Another advantage is the appearance of the packaged product to a consumer, since the liquids are substantially or fully separated from the product, and are kept in the triangular cells, without the use of blood-wetted sublayers.
  • Figure 1(a) shows in perspective view an exemplary embodiment of the container with a bottom having triangular cells and Figure 1(b) shows in detail the bottom and the formed triangular cells.
  • the container with a floor having triangular cells of the invention consists of side walls (1) and a floor manufactured from poly(ethylene terephthalate).
  • This specific material known also as PET, is a fully recyclable material, suitable for use in foodstuff applications, since it does no present any migration of the materials to the packaged foodstuffs. It is completely transparent, with a high mechanical strength and easy to form, so that packages of various shapes and sizes can be obtained. It is apparent that other suitable plastic materials can be used, including polypropylene, polystyrene, polylactic acid, and or transparent, coloured plastic materials, suitable for use in foodstuff applications.
  • the container has a retaining edge (3), which extends over the length of the walls (1) and which functions as a flange on which the individual package cap sticks.
  • the bottom (2) consists of triangular cells (4) over its length and width, which have an exemplary width of 2 mm, without being limited to that, for the retention of the liquids.
  • the triangular cells (4) are derived from sides (5), Fig. 1 (b) , which form acute dihedral angles.
  • the formation of the triangular cells (4) contributes in the retention of the liquids due to the capillary force effect. As it is known, when liquids come in contact with solid body, attractive forces are developed, both between molecules of the liquid, and between molecules of the liquid and the solid. Since the value of both forces is different, the liquids are retained in the cells in an efficient manner. The retention is further enhance due to surface tension.
  • the triangular shape of the cells contributes in the almost absolute covering of the floor (2) of the container, since in the space between two successive triangles another triangle may be further positioned reversely.
  • the nesting of the triangles allows the evaluation of the maximum portion of the floor area, and as a result a significant quantity of water is retained, which may amount to 0.2 g/cm 2 .
