Definitions

  • the present invention relates to a tray-shaped paper container, in particular for foodstuffs to be baked, of the type comprising a flat bottom substantially in the form of a rectangle and side walls adapted to confine a holding space.
  • tray-shaped containers or baking tins obtained from paper material of an appropriate type are generally utilized for cooking mixtures and for the subsequent preservation of the finished products.
  • containers that are each formed of a flat bottom substantially shaped as a rectangle, and of side walls that altogether define a slightly flaring holding space.
  • the longer walls of the containers are provided to be made more rigid by upper tube-like borders, i.e. borders shaped in the form of curls obtained by folding down the flaps projecting from said longer walls.
  • These flaps are comprised of a first portion for formation of the true tubular border and a consecutive end portion that is caused to adhere by sticking to the outer face of the respective side wall.
  • a container for edible fat in the form of a tray-shaped cardboard container provided with an edge flange to which a strenghtening frame is attached.
  • the strenghtening frame extends outwardly and inwardly of the container.
  • the preamble of claim 1 is based on this prior art.
  • containers provided with tube-like borders do not enable an appropriate stacking from the point of view of the volume they occupy, because since these tube-like borders are of a rather important diameter, when they are superposed upon each other they prevent the bottoms and side walls of the stacked containers to get into mutual contact or in any case to be arranged at a very reduced mutual distance.
  • a further object of the invention is to devise a tray-shaped container of strong structure and incapable of deformation even if dampened, in particular during the cooking steps of the mixture housed therein.
  • the aims specified are substantially achieved by a tray-shaped paper container as defined in the claims.
  • the tray-shaped paper container in accordance with the invention is generally identified by reference numeral 1.
  • It comprises a flat bottom 2 of substantially rectangular form, a pair of long side walls 3a and a pair of short side walls 3b generally adapted to form a slightly flaring holding space 4.
  • At least the pair of long side walls 3a that are more subjected to yielding during cooking of the food held in the container, has upper borders 5 of substantially flat conformation and extending parallelly to the bottom 2 externally of the holding space 4.
  • Each of the upper borders 5 is formed of two consecutive flaps, a first flap 6a and a second flap 6b, emerging from a respective first side wall 3a and folded down so as to define a gap 7 between them, said gap extending over the whole length of the upper border itself.
  • auxiliary end portion 6c Extending from the second flap 6b is an auxiliary end portion 6c folded back against the outer face 3c of the corresponding side wall 3a and made integral with the latter by an adhesive substance.
  • the auxiliary end portion 6c therefore locks the upper border 5 to an operating position and, in order to perform this function, it may have even a limited extension towards bottom 2, thereby helping in reducing the paper amount required for each container.
  • substantially flat stiffening means 8 the bulkiness of which corresponds to the volume of said gaps.
  • stiffening means 8 is defined, for each upper border 5, by a stiffening strip of a longitudinal extension substantially corresponding to the extension of border 5.
  • Said stiffening strip comprises a paper support 9 of tubular conformation, in turn comprising a flattened centre portion 9a consisting of two opposite stretches mutually adhering to each other and two longitudinal loops 9b defining the longitudinal contours of the strip itself.
  • the longitudinal loops 9b incorporate a pair of malleable iron wires 10 and are shaped during the manufacturing step of said wires.
  • the stiffening strip 8 is enclosed in a delimited space, defined by gap 7, which prevents any displacement thereof.
  • This circumstance enables the same stiffening strips 8 to exert the maximum strength action in the plane in which they lie and to keep the upper borders 5 constantly parallel to bottom 2, that is horizontal in the normal use position of the container.
  • a strong resistance to deformation is caused in a plane parallel to the bottom, i.e. in the stiffening direction required by the long side walls in order to avoid any swelling.
  • the stiffening means 8 may consist of a stiffening strip exclusively formed of a support of flattened thin paperboard 11.
  • the invention achieves important advantages.
  • containers in accordance with the invention stacked up for transportation and storage, take up very reduced volumes relative to similar containers of known type.
  • a given number of said known containers superposed upon each other is deemed to take up a space which is about three times the space taken up by containers in accordance with the invention having the same capacity.
  • the original substantially-flat upper borders in addition to exerting a strong stiffening action on the long side walls with which they are advantageously associated, also have reduced thickness so that bottoms of the stacked containers are arranged almost completely close to each other.
  • the limited volumes of the containers in accordance with the invention when arranged into a stack enable their transportation, packaging and storage costs to be greatly reduced.
