Definitions

  • the present invention relates to the field of containers for packaging, storage and transportation of foodstuffs, and in particular containers and packages for products requiring drainage or absorption or retaining of their liquids.
  • the container with a floor having star shaped cavities has not been disclosed in the prior art.
  • the known foodstuff packages which are mainly used for packaging and selling fresh protein foodstuff such as meat, poultry, fisheries and similar products, usually consist of a container, in which the product is positioned and which is covered with a transparent, outer, plastic housing or film.
  • this package such as trays comprising of an absorbent pad, usually in the form of a sublayer, between the product and the tray, in order to retain liquids.
  • These sub-layers are typically produced from absorbent paper pulp, while externally they have a coating with flexible polyethylene or other plastic film, so that the pieces of paper pulp that come in contact with the foodstuff do not stick nor come in contact thereto.
  • Such a product is presented for example on US4275811 , aiming at the absorption of liquids, the extension of the lifetime of the foodstuff, the prevention of contamination when the product is kept within liquids for an extended period, and naturally for the aesthetically better appearance thereof to the consumer.
  • these sublayers are perforated, so that the liquids of the meat pass through the covering film into the hydrophilic paper mass and not remain on the surface.
  • trays incorporating the adsorbent surface such as the disk presented on US5709897 , or are focused on the improvement of the adsorbent surfaces, as with the invention described on WO2004099009 .
  • disks as the one proposed on 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 trays with the adsorbent sublayers is the increased cost, which inevitably is conveyed to the final consumer, since the consumer needs to obtain the specific laminated paper pulp sublayer. Given that the paper sublayer is frequently glued to the bottom of the container, further issues emerge, since additional expenses are required for the positioning and gluing, either for the materials, and for the necessary labor, even for the consumed energy.
  • a further object of the present invention is to provide the proposed container with a bottom having star shaped cavities, which is manufactured from the same material constituting the container, (polyethylene terephthalate), also known as PET.
  • PET is a fully recyclable material, does not have toxic ingredients, it is generally safe for use in packaging of most kinds of foodstuffs. 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 extended time period. Finally, it should not be ignored that due to the great transparency of the material it provides cleanness and an optimal visual contact of the consumer with the packaged foodstuffs.
  • a further object of the present invention is to provide a container with a bottom having star shaped cavities, which retains the liquids within the cavities, by exhausting the capillary force phenomenon.
  • a further object of the invention in order to make the container with a bottom having star shaped cavities of the present invention useful, is the formation of star shaped cavities with acute dihedral angles, which can enclose and withhold the liquids stronger than previous inventions, 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 star shaped cavities, which exploits the shape of the cavities, occupying the maximum portion of the bottom area, due to the nesting of the angles of the stars, between them.
  • Another object of the invention is to provide a container with a bottom having star shaped cavities, which has a better liquid retention in the cavities 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 star shaped cavities, 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 it is easily recycled, since it is manufactured exclusively of only one material, the PET, which is fully and easily recyclable.
  • Another advantage of the present invention is that it can be produced of recycled PET, thus its production will consume recycled PET which is the most available plastic material, in quantity, in the market of recycled plastics, due to the high consumption of PET water and beverage bottles.
  • Another advantage is the appearance of the packaged product to the consumer, since the liquids are substantially or fully separated from the product, and are kept in the star shaped cavities, without the use of blood-wetted sublayers.
  • Figure 1(a) shows in perspective view an exemplary embodiment of the container with a bottom having star shaped cavities and Figure 1(b) shows in detail the bottom and the formed star shaped cavities.
  • the container with a floor having star shaped cavities of the invention consists of side walls (1) and a floor manufactured from polyethylene terephthalate.
  • This specific material known also as PET, is a fully recyclable material, suitable for use in foodstuff applications, since it practically does not present migration of the materials to the packaged common 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 for this application, including polypropylene, polystyrene, polylactic acid, also transparent or colored 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 lidding film is sealed.
  • the bottom (2) consists of star shaped cavities (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 star shaped cavities (4) are derived from sides (5), Fig. 1 (b) , which form acute dihedral angles.
  • the formation of the star shaped cavities (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 cavities in an efficient manner. The retention is further enhanced due to surface tension.
  • star shaped cavities with at least 8 legs per star shaped cavity and maximum 18° of dihedral angle at the end of each triangular star-leg, provide greater retaining forces.
  • tests done show that in common wholesale and consumer utilization and transportation of the packaging, the liquids existing on the bottom are held safely within the said bottom star shaped cavities, and do not spill in general within the whole volume of the packaging.
  • the star shaped cavities, with triangular star leg extensions contribute 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.
