Definitions

  • the present invention relates to a tray in a single piece and a method for producing it.
  • Food trays which are made of a material such as cardboard, paper, polymeric sheet and/or a laminate which comprises one or more layers.
  • These trays are generally composed of several parts connected to each other by additional elements glued or non-glued.
  • additional elements can for example be plastic laminated sheets or the like which are absolutely necessary, as otherwise the tray would not be able to sustain itself in an operational position for containing food or similar products.
  • a certain formation complexity is thus achieved, requiring particularly complex machinery in which devices for forming the parts from the initial blank must be combined with devices for feeding additional parts.
  • An actual cover must be made, for example, in line with a laminate of the initial cardboard blank.
  • JP 2006 290368 relates to a tray according to the preamble of claim 1. Furthermore, this document also relates to a method for producing the tray it describes.
  • the general objective of the present invention is to provide a blank and a method capable of solving the above-mentioned drawbacks of the prior art in an extremely simple, economical and particularly functional way.
  • a further objective of the present invention is to produce a particularly rapid tray to be assembled from a single blank without adding parts or additional elements, except for the intervention of a simple glue.
  • a blank is used, punched or sheared, made of material suitable for containing a food product, indicated as a whole with 50 in its unfolded flat position.
  • a main panel 51 is defined in a longitudinal direction L with which a side panel 52 is foldably associated, thus indicated as a whole.
  • the main panel 51 consists of a rectangular frame which comprises two shorter sides 2 and 3 from which two small panels 5 and 4, shaped in the form of isosceles trapezoids, extend in a transverse direction T towards an internal central opening or cutout 53.
  • the above-mentioned frame is continuous and closed, without interruptions.
  • Two longer sides 1 and 6 of the main frame panel 51 are also indicated in the transverse direction T; more specifically, 1 indicates the free terminal side and 6 indicates that with which the side panel 52 is associated.
  • a strip 7 having the same size is juxtaposed with respect to the side 6 of the main frame panel 51, which acts as an attachment portion of the adjacent side panel 52.
  • the side panel 52 comprises a central internal panel 54 from which peripheral panels 8, 10, 13 and 18, shaped in the form of an isosceles trapezoid and extending outwardly from the central internal panel 54, extend on the four sides.
  • peripheral panel 8 extends from the strip 7, which has been seen to act as an attachment portion of the side panel 52.
  • Said peripheral panel 8 called transverse, is arranged transversely in the side panel 52.
  • Said peripheral panel 8 provides at its opposite side ends, two triangular panels 20 and 9 facing the adjacent longitudinal peripheral panels 18 and 10 respectively. These longitudinal peripheral panels 18 and 10 in turn extend outwardly into a panel having a rectangular flap 19 and 11 which will be seen hereunder.
  • transverse peripheral panel 13 opposite the transverse peripheral panel 8 with respect to the central internal panel 54 (also arranged transversely), also has at its opposite side ends, two triangular panels 17 and 12 facing the adjacent longitudinal peripheral panels 18 and 10, respectively. It should also be noted that this transverse peripheral panel 13 extends outwardly into a panel with a rectangular flap 16, also transverse.
  • one 8 of said transverse peripheral panels is associated with said strip 7, which acts as an attachment portion of the side panel 52, and that one 13 of said transverse peripheral panels opposite the previous panel 8 is associated with a panel having a rectangular flap 16.
  • glue lines are naturally further provided, which join overlapping panels or parts thereof.
  • transverse peripheral panel 13 in one of its intermediate areas provides a folding invitation line 15 which thus defines a panel part thereof indicated with 14 close to the central internal panel 54.
  • figure 2 shows how in the blank, from the flat extended position of figure 1 , a first fold is made in its side panel 13 in an intermediate area using the folding invitation line 15. In this way, the part 14 of the side panel 13 remains stationary and the remaining part of the panel 13 is brought to overlap the part 14 and the central internal panel 54.
  • Figure 3 shows how from this second position in figure 2 only the panel with a rectangular flap 16 is folded outwardly, which is thus brought to superimpose part of the side panel 13.
  • the strip 7 of the side panel 52 is provided with a glue line indicated with 56 facing upwards in figure 3 which will then be coupled with the side 6 of the main frame panel 51.
  • the main panel 51 is rotated onto the side panel 52. This occurs thanks to a folding invitation line 57 defined between the side 6 of the main frame panel 51 and the strip 7 of the side panel 52, which, as already mentioned, acts as an attachment portion.
  • the glue lines 55 and 56 thus constrain the main panel 51 to the side panel 52 superimposed on each other as can be clearly seen in figure 4 .
  • this position between the parts is that which is reached by the blank 50 by effecting the above-mentioned foldings and the two gluings indicated.
  • This situation is usually created by the paper industry that produces the blank and which then passes it, thus partially formed, to the user who uses it in the complete shaping machine of the tray to be obtained.
  • Figure 5 shows a section or a view from one end of the blank, when it has been glued as described above, in its various constituent portions, to form the arrangement of figure 4 .
  • Identically figure 6 shows, in a perspective view, how the various panels of the tray being formed appear after the first two gluings of the glue lines 55 and 56 previously described.
  • Figure 7 shows how the various panels are moved together to reach a subsequent step for forming the tray. More specifically, it can first of all be noted that two lines of glue 58 are applied on opposite free side edges of the small-sized panel 4, shaped in the form of an isosceles trapezoid on one side of the tray. On the other side, it can be noted that two lines of glue 59 are applied on opposite free side edges of the panel having reduced dimensions 5, shaped in the form of an isosceles trapezoid.
  • the triangular panels 9 and 12 which extend from the peripheral panels 8 and 13, shaped in the form of an isosceles trapezoid, are folded towards the inside of the tray being formed i.e. towards the central internal panel 54.
  • the triangular panels 20 and 17 are folded, which extend from the peripheral panels 8 and 13, shaped in the form of an isosceles trapezoid, also towards the inside of the tray being formed i.e. towards the central internal panel 54.
  • the small-sized panel 4 is now pushed from one side towards the two triangular panels 9 and 12 so as to bring the glue lines 58 to face each other between the parts ( figure 8 ) in order to glue and constrain the panels together.
  • the small-sized panel 5 is pushed towards the two triangular panels 8 and 13 so as to bring the glue lines 59 to face each other between the parts in order to glue and constrain the respective panels together.
  • Figures 9 and 10 show how to proceed in a subsequent phase when the peripheral panels 18 and 10 are brought into contact with the small-sized panels 5 and 4 respectively.
  • the transverse peripheral panels 18 and 10 are brought to face each other and come into contact with glue lines 60, arranged centrally on the small-sized panels 5 and 4.
  • glue lines 61 are arranged on the panels with a rectangular flap 19 and 11 of the longitudinal peripheral panels 18 and 10 which extend outwardly from the side panel 52. These glue lines 61 are brought to face each other and come into contact with the two shorter sides 2 and 3 of the rectangular frame of the main panel 51, reciprocally blocking each other.
  • the tray is thus formed as shown in figures 11 and 12 both on the short side and on the long side.
  • this type of tray is formed from a single blank and, once the glue lines have been prepared and activated, it is able to remain open by itself without the aid of further sheets of paper or plastic material, such as a lining.
  • the tray is particularly sturdy as the main panel 51, as already mentioned, consists of a rectangular frame in a single piece which comprises two shorter sides 2 and 3 oriented longitudinally in the direction L and two longer sides 1 and 6 oriented transversely in the direction T.
  • the present invention also relates to a method for forming a container for containing a food product.
  • the method can consist of producing a tray comprising a main panel with which a side panel is foldably associated, wherein the main panel, which consists of a rectangular frame comprising two shorter sides and two longer sides, is folded and superimposes the side panel by means of a folding invitation line defined between a longer side of the main frame panel and an adjacent strip of the side panel, said two panels folded over each other and superimposed being at least partially constrained by lines of glue.
  • the method prior to these steps provides for forming a blank or die-cut made of paper material or cardboard for food in a food tray, first in a main panel 51 with which a side panel 52 is foldably associated, wherein said main panel 51 consists of a rectangular frame comprising two shorter sides 2, 3 and two longer sides 1, 6, wherein said two shorter sides 2, 3 extend in a longitudinal direction L and said two longer sides 1, 6 extend in a transverse direction T.
  • This forming step also defines in the blank a central internal opening or cutout 53 of said main panel 51 from whose two shorter sides 2, 3 two smaller panels 5, 4 shaped in the form of isosceles trapezoids, extend in a transverse direction T towards said central internal opening or cutout 53.
  • the method further provides that said side panel 52 extends from one 6 of said two long sides 1, 6 of the main frame panel 51 by means of a strip 7, which acts as an attachment portion of the side panel 52.
  • an internal panel 54 is defined in said side panel 52, central to the same, from which two transverse peripheral panels 8, 13 and two longitudinal peripheral panels 10, 18, in the form of an isosceles trapezoid, extend outwardly, on all four sides, from the central internal panel 54.
  • the method provides that one 8 of said transverse peripheral panels be associated with said strip 7, which acts as an attachment portion of the side panel 52, and one 13 of said transverse peripheral panels, opposite the previous one, is associated with a panel with a rectangular flap 16.
  • the method provides that glue lines 55, 56, 58, 59, 60, 61 be arranged on the panels for joining overlapping panels or parts of them.
  • the one transverse peripheral panel 8 provides for the formation of two triangular panels 20, 9 at its opposite side ends facing the adjacent longitudinal peripheral panels 18, 10.
  • said longitudinal peripheral panels 18, 10 in turn extend outwardly into a longitudinal panel with a rectangular flap 19, 11.
  • the method provides for forming, at its opposite side ends, two triangular panels 17, 12 also facing said adjacent longitudinal peripheral panels 18, 10, wherein said other transverse peripheral panel 13 extends outwardly into said panel with a rectangular flap 16.
  • the method then preferably provides steps wherein said strip 7, which acts as an attachment portion of the side panel 52, said longitudinal rectangular flap panels 19, 11 and said panel with a rectangular flap 16 are provided with glue lines 56, 61, 55.
  • the transverse peripheral panel 13 in an intermediate area thereof provides a folding invitation line 15 which thus defines a panel part 14 of the same close to the central internal panel 54.
  • the two panels having reduced dimensions 5, 4 of said main panel 51 are provided with two lines of glue 58 on opposite free side edges.
  • glue lines 60 are arranged centrally on the small-sized panels 5, 4 which in turn are brought to face each other and come into contact with said transverse peripheral panels 18, 10.
  • glue lines 61 are arranged on panels with a rectangular flap 19, 11 of the longitudinal peripheral panels 18, 10 which extend outwardly from the side panel 52 and said glue lines 61 are brought to face each other and come into contact with the two shorter sides 2, 3 of the rectangular frame of the main panel 51, blocking each other.
  • Figures 13 to 24 show similar views and positions for a second embodiment of a blank useful for forming a tray according to the invention.
  • triangular panels 21, 22 and 23, 24 respectively which extend from the two panels having reduced dimensions 5, 4, shaped in the form of isosceles trapezoids, of the main panel 51 with a rectangular frame.
  • these triangular panels 21, 22 and 23, 24 respectively, extend from the tilted sides of the isosceles trapezoids and rest on the transverse peripheral panels 8 and 13 towards the inside of the tray being formed i.e. towards the central internal panel 54.
  • These triangular panels 21, 22 and 23, 24 respectively provide a reinforcement at the edges of the tray when formed by the folding of the various panels.
  • a blank and a method are therefore created which are particularly suitable for the formation of a tray deriving from a blank or die-cut in a single piece which is formed and kept in its operating condition for receiving food exclusively thanks to the arrangement of its panels and glue lines that keep them constrained to each other, without adding other kinds of materials or sheets.
  • a plastic barrier lining can be applied to the inside so that food that releases a liquid portion can be accommodated.
