Definitions

  • the object of the present invention is an egg container shaped as an alveolar structure tray.
  • Egg trays consisting of a plurality of cavities and provided with means for piling thereof on top of one another are already known and used.
  • FIG. 1 One of such handling devices recently proposed is schematically represented in figure 1 with reference numeral 50 and comprises an articulated arm 55 from the end whereof a plurality of parallel forks 60 extends, for example in the shape of cylindrical rods. Said arm 55 is guided by an operator so that forks 60 insert between two egg trays piled on each other for picking up and moving a pile of trays.
  • the egg trays currently used are not provided for being handled by such fork device, since it is not possible to insert the forks between two adjacent trays.
  • someone has tried to pile up the trays upturned, that is, with the cavities facing downwards. In this way, the forks can be inserted in the empty space between two rows of cavities.
  • the use of upturned trays does not offer the same functional advantages that can be obtained by the same trays oriented correctly, so it is necessary to provide an operation for tilting the pile of trays in correct position.
  • the object of the present invention is to propose an egg tray suitable for being used with a fork tray handling device of the type mentioned above.
  • figure 1 shows a schematic view of a tray handling device
  • figure 2 shows a perspective top view of the egg tray according to the invention
  • figure 3 shows a perspective bottom view of the tray
  • figure 4 shows a front view of the tray in the direction of the forks
  • figure 5 shows a side view of the tray
  • figure 6 shows a schematic view of a plurality of trays handled by the device of figure 1.
  • reference numeral 1 globally denotes an egg tray according to the present invention.
  • the tray has a structure comprising a plurality of cavities 11 arranged in parallel rows.
  • Cavities 11 extend from a base 5 delimited by an external edge 2.
  • edge 2 defines a horizontal plane 5 wherefrom cavities 11 protrude.
  • the tray has a rectangular shape, for example square.
  • the tray is made of a plastic material.
  • Each cavity 11 is suitable for receiving the top portion of an egg contained in an equal underlying tray of a pile of trays.
  • each of said cavities 11 is completely closed at the top, for example by a horizontal top plane 12.
  • a projection 13, moreover, can extend upwards from said plane 12.
  • a truncated-cone or truncated-pyramid projection 14 extends from each portion of base 5 comprised between four adjacent cavities, suitable for abutting on a top plane 12 of a cavity 11 of an underlying tray.
  • Projections 14 of a tray act as spacer elements between two superimposed trays, so that the eggs contained in the underlying tray are not squashed.
  • At least some projections 14 are hollow or comprise a seat 15 suitable for receiving projection 13 of a cavity of an underlying tray.
  • the coupling between projections 13 and relevant seats 15 allows a steady superimposition of a plurality of trays on top of one another.
  • At least one side of edge 2 of tray 1 there are obtained at least two seats 20, each suitable for allowing the passage between two superimposed trays of a fork 60 of a handling device 50, like that schematically shown in figures 1 and 6.
  • At least one side of edge 2 has, suitably spaced from one another, at least two cavities or recesses 20.
  • the tray ends with a row of half cavities, each closed by a vertical wall 3.
  • seats 20 are obtained as openings that from the edge extend in said walls 3 of the half cavities.
  • Said seats 20 are aligned to the passage or channel 21 laterally delimited by two adjacent and parallel rows of projections 14. In other words, looking at the tray from the front (figure 4) seats 20 are aligned to the axes of symmetry of cavities 11 of a row of cavities.
  • the concavity of seats 20 is equal to or greater than the concavity of concave walls 22 so that the entire tray 1 rests on forks 60, rather than only edge 2 thereof.
  • the depth of seats 20 relative to edge 2 is greater than or at most equal to the concavity of concave walls 22 relative to the tray base.
  • seats 20 allow the insertion and passage of forks 60 between two superimposed trays, but advantageously at least the concave walls 22 abut on forks 60. This ensures high stability of the pile of trays when handled by device 50, also and above all when the trays are full of eggs.
  • seats 20 are obtained in two opposite sides of tray 1, so that forks 60 are free to extend by the entire length of the tray and beyond.
  • seats 20 and concave walls 22 have a shape complementary to the section of forks 60.
  • seats 20 and concave walls have a semicircular or rectangular or polygonal, in general, shape.
  • each cavity further exhibits four external openings 17 or, as an alternative, four concave recesses 17, on the edge whereof the egg inserted between four adjacent cavities is inserted.
  • each of them corresponds, on the inner side of the cavity, to a convex zone, so that the top portion of each egg is firmly held between the four convex zones of the corresponding cavity of the above tray.
  • cavities 11 can advantageously be provided, in the proximity of the top plane 12, with a notched or step-wise portion 18 suitable for being engaged by a device for the top pick up of single trays.
