Definitions

  • the present invention relates to a food tray, in particular a tray provided with a tamper-evident closure.
  • Such trays are normally provided with a cover hinged on one side of the edge and which is made in one piece therewith.
  • a frequent problem is related to the ease of opening and closing the cover, whereby it is difficult to subsequently understand if third parties have had access to the contents of the tray and have then placed it back on the shelf.
  • the trays are provided with an adhesive tab joining the cover and the edge, it is sometimes possible to partially detach the tab and then make it adhere again, without an obvious trace of having opened the tray.
  • trays with tamper-evident closure have been suggested, which provide for the at least partial removal of a tab placed at the hinging portion and also made in one piece with the rest of the container.
  • This solution although effective for the purpose pursued, is however relatively expensive to manufacture.
  • the partially detached tab increases the volume of the tray when the consumer, having withdrawn a part of the contents, places it in the refrigerator for storage.
  • the problem addressed by the present invention is that of providing a food tray which is simple and inexpensive to manufacture, simple to use and with a small volume.
  • the present invention relates to:
  • the tray indicated as a whole by numeral 1, comprises a bottom 2, side walls 3, a rear wall 3a and a front wall 3b, extending in elevation from the bottom 2, and a cover 6 hinged to said rear wall 3a and made in one piece with the tray 1.
  • the tray 1 further comprises a peripheral edge 4 extending outwards from the upper end of the walls 3, 3a, 3b.
  • the tray 1 can be made of a plastic material normally used for this type of application, sufficiently elastic and deformable, for example polypropylene or polyethylene terephthalate and can be made by hot molding (thermoforming) or injection.
  • the walls 3, 3a, 3b can be slightly flared in shape and are connected by angular portions 5, preferably beveled or curvilinear in shape.
  • the angular portions 5 can have ribs or channels, so as to form stiffening elements.
  • the bottom 2 can be smooth or have a slightly raised central portion of width such as to occupy at least 80% of the total surface of the bottom 2.
  • the edge 4 comprises a stepped section formed, in succession from the upper end of a wall 3, 3a, 3b, by an abutment plane 4a, a step having a rise 4b and a tread 4c, and a rib 4d from which a vertical side 4e departs outwards, which preferably ends at the level of the abutment plane 4a.
  • the rib 4d comprises an elevation 7 extending for example over a third or more of the width of the front wall 3b.
  • the cover 6 comprises a flat portion 6a, a front edge 6c, a rear edge 6d and side edges 6e, 6f.
  • edges 6c, 6d, 6e, 6f of the cover 6 have a stepped-profile cross-section 10, comprising a first flat portion 10a, a rise portion 10b and a second flat portion 10c, where the first flat portion 10a, the rise portion 10b and the second flat portion 10c are configured to abut against the abutment plane 4a, the rise 4b and the tread 4c of the edge 4 of the tray 1, respectively, and to snap-fit therewith.
  • a coupling is obtained by the interference between the various surfaces and the deformability of the material with which the tray 1 is made.
  • rib 6b rises concentrically, which is interrupted at the height of the midpoint of the front edge 6c, where the flat portion 6a comprises a cavity obtained by deformation of the flat portion 6a and which therefore defines a downwardly projecting pin 9.
  • the cover 6 is hinged to the edge 4 of the rear wall 3a by a hinged portion 8.
  • the hinged portion 8 joins the lower end of the vertical side 4e with a tab 8a extending from the rear edge 6d of the cover 6 and comprises a corrugated surface 8b having a fretted profile in section, i.e., formed by segments alternately arranged in perpendicular and parallel lines.
  • the corrugated surface 8b thus configured allows obtaining a good elasticity, favoring the closure of the cover 6 on the tray 1.
  • the front wall 3b of the tray 1 comprises a recess 11 formed at the central portion of the front wall 3b and comprising a connecting portion 12 with the edge 4.
  • the connecting portion 12 comprises, on the upper surface, a cavity 12a defining a deformable button 13 facing downwards.
  • the cavity 12a is arranged in vertical alignment with the pin 9 of the cover 6 and accommodates it at least partially when the cover 6 is in the closing position.
  • the deformable button 13 under the bias of the pressure of a user's finger, is configured to deform until it protrudes, at least partially, upwards and presses against the pin 9 of the cover 6, causing it to open.
  • the tamper-evident tray 1 works as follows. When the cover 6 has been closed on the body of the tray, matching the respective edges thereof by snap-fitting, the pin 9 is positioned in vertical alignment with the recess 12a. The rib 4d and the elevation 7 protruding further therefrom prevent gripping the stepped profile 10 of the edges 6c, 6d, 6e, 6f of the cover 6, so that the user cannot lift the cover 6 to open the tray.
  • the only way to open the tray 1 is to press the button 13, so as to apply a pressure to the pin 9 of the cover 6 and cause it to lift, as shown in figure 4B .
  • a pressure on the deformable button 13 causes the irreversible deformation thereof. If the tray 1 were then closed again, a subsequent buyer would notice the tampering by virtue of the permanent deformation of the button 13.
  • the recess 11 of the front wall 3b can comprise instructions, obtained for example by relief deformation of the material, with the function of inviting to press the button 13 to open the tray 1.
  • the tray 1 according to the invention allows achieving the preset purposes. In fact, it is fact simple to manufacture, is compact and does not have protruding elements of such a size as to impact the overall volume of the tray. The tamper evident system is also simple and effective.
