Definitions

  • This invention relates to a food-carrying cardboard tray.
  • a drawback of the above trays is that they have a low stiffness to lateral compression, so that they are readily misshapen during transport, handling or storing on shelves and benches when offered on sale.
  • automatic packaging machines are widely used for the on-site packaging of fresh foods, typically in markets and supermarkets, which machines are arranged for operating with trays of a stiff material such as polyethylene or the like, and are capable of wrapping a protective film onto the trays as they are filled up by the staff.
  • aligning the ring onto the tray ledge during the gluing step is a complex operation that is difficult to be implemented on conventional processing lines used for manufacturing cardboard trays.
  • Another object of the invention is to provide a tray that can be manufactured on conventional production lines, by adopting operations that are simple and easily automated in the usual tray-manufacturing processes.
  • a cardboard tray 10 has a flat bottom 12 and a peripheral wall 14, whose upper edge extends to form an overhanging ledge 16.
  • Flat bottom 12 has a substantially rectangular shape with rounded corners.
  • Peripheral wall 14 comprises two major side walls 14a and two minor side walls 14b, which are connected by corrugated corner walls 14c located at the rounded corners of bottom 12.
  • Ledge 16 extends continuously along the edge of the peripheral wall 14, and it accordingly comprises straight portions such as 16a, 16b adjacent side walls 14a, 14b, and curved portions such as 16c adjacent corner walls 14c.
  • the corrugations made on corner walls 14c also extend to curved portions 16c of ledge 16.
  • ledge 16 has reinforcing side flaps 18, 20 and reinforcing corner flaps 22 that are folded and glued to the underside of the ledge. More particularly, reinforcing side flaps 18, 20 respectively extend along the straight portions 16a, 16b of the ledge, while reinforcing corner flaps 22 extend along the curved portions 16c and are also corrugated so that they accompany the rounded profile of the ledge.
  • a tray according to the invention is made from a cardboard sheet 24 that has been dinked or die-cut in a substantially rectangular shape with rounded corners 26.
  • the dotted lines on Fig. 2 indicate the lines along which the sheet will be folded in order to form the tray.
  • notches such as 28 are cut to define side strips such as 30, 32 and corner strips such as 34, which are respectively intended to provide the reinforcing side flaps and the reinforcing corner flaps for the tray.
  • Sheet 24 is thermoformed in a mould so that it acquires the desired hollow shape of tray 10. More particularly, the tray bottom 12 comprises a central portion of the sheet that is bounded by dotted line L1 shown on Fig. 2; the peripheral wall comprises an intermediate band of the sheet that is bounded externally by dotted line L2; the ledge 16 comprises an outer band on the sheet, which is bounded by dotted line L3. Side strips 30, 32 and corner strips 34 are designed to be folded and glued to provide the above reinforcing flaps 18, 20 and 22.
  • the reinforcing side flaps such as 118 and the reinforcing corner flaps (not shown) are folded and glued onto the upper side of the ledge.
  • the rounded corners of the cardboard sheet are provided with a number of notches such as 228, which give rise to several side-by-side corner strips such as 234.
  • a number of notches such as 228, which give rise to several side-by-side corner strips such as 234.
  • side-by-side reinforcing corner flaps are formed rather than a single flap. It should be understood that in this case, too, the flaps may be folded and glued either onto the upper or the under side of the ledge.
  • the main advantage of the second embodiment is that it reduces deformations and stresses in the cardboard corner flaps. This reduction may be necessary or not, depending on the characteristics of the specific cardboard used.
  • the reinforcing side flaps 318 and the reinforcing corner flaps are folded onto the underside of the ledge and extend further along the outside surface of the peripheral wall of the tray.
  • the reinforcing side flaps 418 and the reinforcing corner flaps are folded onto the upper side of the ledge and extend further along the inside surface of the peripheral wall of the tray.
  • the reinforcing side flaps might extend only over a fraction of the side wall of the tray rather than down to its bottom as shown in the Figures.
