Definitions

  • the invention refers to a tray structure for packaging bulk or small-size products and, particularly, but not exclusively, for foodstuff.
  • the invention has the object to provide a tray which has such specific characteristics as stability, heat insulation, possibility of stiffening the side walls to withstand for long times the presence of products with high level of humidity, and also products which can give rise to separation of liquids, or anyway the presence of liquid, in the product to be packaged.
  • Another object is to provide an article easy to assemble and substantially economical to produce and, in particular, which makes use of economical starting materials.
  • the tray-like package according to the invention for bulk products, especially foodstuff, is substantially made up of two components in laminar material:
  • the side walls and the bottom of the internal tray make up dihedrals which are larger than those formed by the side walls and the bottom of the external tray.
  • side walls having substantially triangular section and with three thicknesses of laminar material are formed, which side walls are therefore particularly rigid.
  • Edges between adjoining side walls converging towards a same corner of one or each tray may consist of triangular or bellow-shaped elements joined together by glueing them to one of the side walls.
  • the first laminar component may be made of a material suited for contact with foodstuff, whereas the other component may be of a different type and able to be treated for typographical printing or the like without difficulty.
  • the dimensions of the two matched trays are such as to form an interspace apt to provide a heat insulation and to allow for accumulating any liquids to be separated from the content of the internal tray formed by the first component; to this end, the latter may be provided with a suitable perforation.
  • a first component 1 which is the one intended to define the tray surface in contact with the product to be packaged, and which is shown in particular in Fig. 1, comprises a rectangular bottom 101 delimited by folding lines 103 and 105 which are opposed two-by-two. Beyond the folding lines 103 are regions 107 having elongated, substantially trapezoidal development, while regions 109, which are also trapezoidal but have a smaller development, extend beyond the folding lines 105. Each of the regions 107 is delimited by the folding line 103 forming the minor parallel side of the trapezium, by a folding line 101 , forming the major parallel side, parallel to line 103, and by two inclined cuts 113.
  • the trapezoidal regions 109 are delimited by the folding lines 105 forming the minor parallel sides, by folding lines 115 defining the major parallel sides and by inclined folding lines 117.
  • the trapezoidal regions are shaped as an isosceles trapezium.
  • triangular elements 119 are provided, which are delimited by said folding lines 117 and said cuts 113.
  • provision may be made so that the die-cut material which forms the component 1 will have folding lines equivalent to lines 117 rather than cuts 113, in order to maintain the continuity of said material.
  • a folding line will be formed along the bisecting line of the vertex which is turned towards the bottom 101 in order to create bellows-like portions, instead of portions which are superimposed upon assembly, as indicated below.
  • end regions 121 are formed, which are trapezoidal as well and symmetrical with respect to regions 107; correspondingly, further end regions 123 are formed beyond the folding lines 115 as well, such regions 123 being also trapezoidal and similar to regions 109.
  • the end regions 121 and 123 are substantially symmetrical with respect to the folding lines 111 and 115 which define the major parallel sides.
  • Fig. 2 shows is the development of a second component 3 which defines the outer surface of the finished tray.
  • This component 3 has a rectangular bottom substantially equivalent to bottom 111 and delimited by folding lines 303 along the longer sides and 305 along the shorter sides.
  • Formed beyond the folding lines 303 are external trapezoidal regions with the minor parallel side extending along the line 303, and the major parallel side being delimited by a cut 309 parallel to the folding line 303.
  • Similarly formed beyond the folding lines 305 are external trapezoidal regions 311 whose major parallel sides are formed by end cuts 313 parallel to the folding lines 305.
  • the external trapezoidal regions 307 and 311 have an isosceles trapzium shape and are delimited by inclined lateral folding lines 315 and 317 for the regions 307 and 317 respectively. Pairs of triangles 319 symmetrical with respect to the folding line 321 develop between the folding lines 315 and 317 which converge to the same corner of bottom 301.
  • each of the two components is assembled in the manner described below, and the two components assembled to form the tray are matched always in the manner described below.
  • the component 1 once bent along lines 103 and 105, makes up an internal tray with side walls formed by the regions 107 and 109 which have inclined development.
  • the triangles 119 are matched against the outer surface of side walls 107 and glued thereto.
  • the triangular elements 119 are folded twice along the bisecting line and moved against the outer surface of one of the adjoining side walls 107 and 109 to stabilize the tray formed by the element 1.
  • the trapezoidal end regions 121 and 123 remain movable along the edges defined by the folding lines 111 and 115, as can be seen in particular in Fig. 5.
  • the side walls 307, 311 are folded, and the bellows-like triangles 319 are also folded along lines 321 and along lines 315, 317 as well, so that the two triangles 319 between the two adjoining side walls 307 and 311 will be located inwardly and be matched along lines 315 and 319 which are brought close to each other, while one of the two triangles is preferably glued against one of the adjoining side walls 311 and 307.
  • the cut edges 309 and 313 of the external tray formed by the element 3 will correspond to the folding lines 111 and 115 of the inner element 1, so that said edges 309 and 313 will be between the side walls 107, 121 and respectively 109, 123.
  • a tray structure which has perimetrical side walls of triangular cross-section with three thicknesses 109, 309 and 123 and respectively 107, 311 and 121. These side walls are particularly stiffened by their conformation and also thermally insulated owing to the presence of an inside interspace.
  • the two bottoms 101 and 103 - owing to the dimensions chosen for the side walls and for the folding lines 115 and 111 - will be slightly spaced apart one from the other, thus giving rise to a limited iter-space also in the bottom, the latter consisting of the two portions of components 1 and 3, i.e. of the two bottom portions 101 and 301.
  • the only surface entering in direct contact with the tray-packaged foodstuffs is the inner upper surface of component 1. Accordingly, the surface treatment required for foodstuff containers may be limited to the component 1 only and, in particular, to the face thereof which forms the inner surface of the tray.
  • cuts 113 are provided as shown in Fig. 1, the only possible contact of the foodstuff with the material of component 1 whose surface is not treated, is limited only to the thickness of the same material remained uncovered along the cuts 113. This may be avoided (likewise in the arrangement 315, 317, 319, 321) by providing triangles 119 with folding lines which replace cuts 113, and with folding lines along the bisecting line of the angles which converge towards the bottom 101 of triangles 119. In this case any contact between the foodstuff and the glue fixing the angles and the side walls defined by component 1 is also avoided.
  • holes 130 may be provided in the bottom and/or the lower part of the side walls defined by regions 107 and 109.
