Definitions

  • the present invention relates to a high strength box-like container, in particular for fruit products.
  • the cardboard trays can not be stacked beyond a set stacking height, and the thickness of the used board material can not be decreased under a set limit thickness.
  • the cardboard containers must be stored in moisture environment, such as for example refrigerating chambers for preserving fruit products, said containers must be made starting from a paperboard or cardboard material which is paraffined on its two faces.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a cardboard container which has a great strenght, can be easily stacked in a full condition on other like containers to a high height and moreover can be made starting from cardboard sheets having a very reduced thickness.
  • a main object of the present invention is to provide such a cardboard container which can be also used in moisture environment without requiring paraffined surfaces.
  • Another object of the present invention is to provide such a cardboard container which is very advantageous with respect to conventional cardboard containers, from the storing and shipment standpoint.
  • Yet another object of the present invention is to provide such a cardboard container which can be easily re-used.
  • Yet another object of the present invention is to provide such a cardboard container which is fully biodegradable.
  • Yet another object of the present invention is to provide such a cardboard container which can be made with a reduced amount of row cardboard material.
  • a high strength box-like container in particular for fruit products, comprising a corrugated cardboard body defining a holding space, which, at the top thereof, is delimited by a bottom wall and, on the perimeter thereof, by sidewalls bent on the top of the bottom wall, characterized in that it comprises at least a stiffening element which is rigidly connected with said bottom wall and associated with two opposite sidewalls of said body.
  • the box-like container or tray according to the invention which has been generally indicated by the reference number 1, comprises a body 1 which has been made by die-cutting and folding a corrugated cardboard sheet.
  • the used cardboard sheet can have a substantially rectangular configuration, with two fodling lines 3 and 4 preformed during the die-cutting operation, which folding lines extend parallel to one another near the major sides of the sheet, and with two folding lines 5 and 6 which extend perpendicularly to said folding lines 3 and 4 near the minor sides of the sheet.
  • perimetrical portions 7, 8, 9 and 10 which can be folded, along the above mentioned folding lines, on the top of the central portion 11 of the sheet, so as to provide the side walls of the container or tray body.
  • the portions 8 and 10 arranged near the minor or short sides of the sheet, are provided with flaps, respectively indicated at 12 and 13, which can be folded toward the inner side of the container body along the preset folding lines 14 and 15 which are parallel to the folding lines 5 and 6.
  • the flaps 12 and 13 are arranged in a plane which is substantially parallel to the laying plane of the container bottom 11.
  • the portions 8 and 10 are provided with side flaps 16, which can be superimposed on the inner sides of the portions 7 and 9 and bent on the top of or above the bottom 11.
  • flaps 12 and 13 are provided with end flaps, respectively indicated at 12a and 13a, provided for being superimposed on the outer side of the flaps 16.
  • the container construction above disclosed further comprises at least a stiffening element 17, which is connected to the bottom wall 11 of the body 2 of the container or tray, and which is associated with two opposite sidewalls of the body 2, preferably the sidewalls 7 and 9 which extend along the major sides of the body of the container.
  • the stiffening element 17 has a plate-like configuration and is arranged on a plane which is substantially perpendicular to the bottom wall 11.
  • the stiffening element 17 is provided, at the bottom thereof, with at least two flaps 18 and 19 which are laterally folded on opposite sides of the laying plane of the remaining portion of the stiffening element.
  • the mentioned flaps 18 and 19 are rigidly connected to the bottom wall, preferably by means of glues or adhesive resins compatible with food products and of a high biodegradability.
  • connection of the stiffening element 17 with the sidewalls 7 and 9 of the container body is preferably made by providing the stiffening element, at its side end portions, with projecting shoulders 20 and 21 which can be fixedly restrained or engaged in seats or recesses 22 and 23 defined by cut-outs, provided near the top edge portions of the side walls 7 and 9, at an intermediate portion of their extension.
  • the siffening element is also made by die-cutting a corrugated cardboard sheet.
  • the sheet used for making the stiffening element is bent or folded along an intermediate folding line, or along two middle lines near one another, so as to obtain, for said stiffening element, a thickness which is double in its portion which extends perpendicularly to the bottom wall 11 of the container body.
  • the stiffening element 17 can be constituted by a single stiffening element and, in this case, it will be arranged at an intermediate plane, preferably the cross intermediate plane of the container, or several stiffening elements can be also provided, possibly arranged with a crossed configuration.
  • the container according to the present invention owing to its greater strength, does not require any paraffining operations and, accordingly, can be easily re-used.
  • a further advantage is that the subject container can also hold two different types of products in the two portions thereof which are separated by the stiffening element.
