Definitions

  • the invention relates to a stackable carrier for take-away foods such as pizza and similar products. It has become a standard practice in recent times for the consumer to purchase foods prepared by a specialist retailer, for example a pizzeria or a pâtisserie, and take them home for subsequent consumption.
  • This method is used currently only to wrap single pies, or pizzas, and requires the precaution of positioning a cardboard form over the dish so as to prevent the paper wrapper from coming into contact with its uppermost surface, which is generally soft and sticky.
  • a more practical method, and one that is essential where there are several pizzas to be carried, is to place each single item in a rigid container that will take the weight of further containers stacked above it; in this way, crushing is avoided, and the items on top are prevented from sticking to those beneath.
  • the containers in question are, in most instances, plain cardboard boxes fashioned in the appropriate dimensions with lids to enable introduction of the food.
  • a further drawback stems from the fact that plain cardboard boxes are completely smooth, and the topmost boxes of a stack can easily slide off.
  • containers have subsequently appeared fashioned in a tray type format from thin plastic material, with sides that are splayed upwards and exhibit sockets the reverse sides of which project out and downwards.
  • the sockets are provided in even number and spaced apart at uniform distance, sunk to two different depths, and alternated in such a way that one tray can either fit snugly into another, or be raised from it through a distance equal to the difference between the dissimilar depths, according to which of the two sets of sockets are aligned.
  • the temperature values and the thickness of the tray material cannot be varied to compensate for such contingencies, however, in view of the fact that a pizza, in particular, must necessarily be served and eaten hot, as if straight from the oven, otherwise one loses those gastronomical features typical of the dish, i.e. its unmistakable taste and flavour.
  • the thickness of the tray this cannot increase beyond a certain point without comprising the economy of manufacture, and in practice, even were the thickness of the plastic material to be increased, the temperature generated internally of the covered tray would still remain higher than its softening temperature.
  • a further drawback of the trays in question stems similarly from the airtight seal that is created by covering the tray, namely, that with vapour given off by the hot pizza being unable to escape, the baked dough becomes soggy, and the taste inevitably suffers.
  • the object of the present invention is one of providing a stackable carrier for pizzas and similar food products, that remains free from the drawbacks mentioned above.
  • a carrier as characterized in the appended claims, which is fashioned from a single sheet of cardboard punched with creases and cuts in such a way as to fold into a base with side walls.
  • a given number of adjoining walls are of dissimilar height, and their corresponding longitudinal ends extend into flaps that are fashioned by making cuts along the creases which unite the walls with the base; the height of the flaps is matched to that of the lower of the side walls, and each two adjoining flaps can be folded together to bridge the relative corner of the base at an oblique angle, creating an additional strengthened wall to take the weight of the carriers stacked above.
  • One of the advantages of a carrier according to the invention is that of its strong stacking potential, achieved notwithstanding the use of relatively thin cardboard, without the carriers sliding in relation to one another, and without any danger of the lower carriers being crushed.
  • the side walls are arranged in a polygonal formation, abundant in number, and at given points are several times thicker than the flat unfolded sheet. What is more, using cardboard of limited thickness, it becomes possible to stack and store a generous number of the flat unfolded sheets in a relatively small space.
  • a further advantage of the carrier disclosed is that one eliminates the possibility of either the carrier or its contents tending to deteriorate due to the high temperature of the contents themselves. Even in situations where several pizzas are stacked straight from the oven for immediate take-away, the cardboard material is able to withstand their high temperature comfortably; moreover, the temperature level in question will always remain within safe limits, as the carrier is never sealed in totally airtight fashion, a feature singularly advantageous from the standpoint of retaining the taste and the flavour of a dish such as pizza.
  • a take-away food carrier according to the present invention denoted 19 in its entirety (fig 2), is fashioned from a single flat sheet of material punched with creases 2 and cuts 3 in such a way that it can be folded into a base 4 surrounded by side walls 5 and 6.
  • the flat sheet 1 for a carrier 19 according to the invention is punched with oppositely paired side walls 5 and 6, certain or all of which (depending to the embodiment) extend into respective flaps 7 and 8 at each end; according to the invention, the walls of one pair 5, 6 are dissimilar in height to the walls of the other pair 6, 5.
  • the flaps 7 and 8 are fashioned in each respective wall 5 and 6 by punching cuts 9 along the line of the crease 2 that separates the wall 5 or 6 from the base 4; more exactly, the length of each flap 7 and 8 is such that the flap itself will not extend beyond the wall 6 or 5 toward which it projects, whilst its height is substantially equal to that of the lower pair of side walls 5.
  • Each of the single flaps 7 and 8 hinges with the relative side wall 5 and 6 by way of a transverse crease 20.
  • One of the two flaps of each adjoining pair 7 and 8 extends into a folding tuck 10 that is hinged along a full-length longitudinal crease 11 and provided with a lug 12 on its projecting longitudinal edge.
  • 13 denotes an angled slot punched into each corner area of the base 4, serving to receive the lug 12 of the relative tuck, as will shortly be described.
  • 14 denotes a substantially central cutaway profile punched into the projecting longitudinal edge of each higher side wall 6, which, with the carrier 19 folded into shape, plunges to a level below that of the top edges of the two lower side walls 5.
  • the tucks 10 are associated with the flaps 8 of the higher side walls 6 in order to reduce waste; furthermore, the cut 3 separating each two adjoining side walls 5 and 6 is mitred in such a way as to obtain maximum length on the flaps 7 and 8 while minimizing waste.
  • the sheet 1 can be punched from any given type of cardboard or paperboard, whether of single ply, or sandwich composition as illustrated in fig 2, and in a preferred embodiment, the internal surface will be faced either entirely, or over the areas destined to make contact with the edible product, with a suitable material such as aluminium foil.
  • the user first bends the two lower side walls 5 upward along their respective creases 2, then turns the flaps 7 of each wall 5 inward toward the middle of the base 4, effecting folds at the relative transverse creases 20. This same procedure is then repeated for the two higher side walls 6 and their flaps 8, whereupon these same flaps 8 are offered flush to the previously folded flaps 7, and the tucks 10 folded inwards and down to the point at which their lugs 12 locate in the corresponding slots 13 (fig 2).
  • the carrier 19 is ready to accept a pizza, pie, flan or other edible product, whereupon it can be stacked as in fig 3.
  • a carrier 19 thus embodied is notably lightweight, due to the fact that a relatively thin yet strong material can be selected for the flat sheet 1; more exactly, the bulk of the weight in a multi-carrier stack is taken by key parts, i.e. the flaps 7 and 8 and the tucks 10, which form vertical walls that are three times the thickness of the sheet 1, and combine with the remaining side walls 5 and 6 to form a polygon having a generous number of sides.
  • one of the lower side walls 5 is provided with a flap 15 of dimensions identical to those of the base 4, which is designed to function as a lid.
  • the lid 15 is provided with a tab 16 that inserts into a corresponding slot 17, formed in a tongue 18 extending from the opposite low side wall 5, when the carrier 19 is shut by lowering the lid 15 into contact with the folded flaps 7, 8 and tuck 10.
  • the slot 17 can be created by punching a C-shaped cut in the tongue 18, so that in bending the tongue 18 horizontal from the upright wall 5, an upwardly projecting stop 24 is created that will prevent a carrier 19 stacked next above from sliding off the relative edge.
  • the flaps 7 and 8 are included only at the two ends of the side wall 5 provided with the tongue 18 and at the adjoining ends of the high side walls 6, respectively; notwithstanding this difference, the basic design of the carrier 19 remains the same as described above with reference to fig 2.
  • each of the higher side walls 6 exhibits a central section 6a of increased height, which can be used as a handle.
  • Each such central section 6a is punched with two push-out tabs 6b positioned in such a way as to lie vertically aligned in relation to the base 4 once the carrier is folded into shape.
  • each tab 6b is located in the manner of the two illustrated in fig 6, the top tab of the bottom carrier aligns with the bottom tab of the top carrier.
  • the bottom tab on each side can be pushed through, and with it, the corresponding top tab of the lower carrier, locking the two carriers together along their side walls 6 and creating a ventilation hole at either side.
