Definitions

  • the invention relates to a bowl-shaped packaging made of cardboard or the like, with a base and hinged side walls, which are connected to one another by double gusset corners arranged between the side walls.
  • Such a packaging is known from DE-C-34 05 177, which is designed to be very complex for the stable and dense formation of the corner regions.
  • the object of the invention is to provide packaging of the type mentioned which is easy to erect and nevertheless has sufficient stability.
  • This object is achieved in that a nose-shaped projection is formed on the outer corner of the gusset when the package is unfolded, which engages when the folded gusset corners are placed on the outside of the adjacent side wall over the gusseted corner folded underneath and lies directly against the side wall.
  • the packaging is made from a cardboard that is exclusively coated on the inside with a sealable plastic, such a configuration leads to stable packaging.
  • the nose-shaped projection is sealed on the outside of the side wall on which the other gusset corner is formed.
  • This nose-shaped projection holds the gusset corner underneath with it, without this having to be defined itself.
  • a further advantageous embodiment of the invention resides in that sealing tabs extending at least approximately over their entire length are articulated on the edges facing away from the bottom of at least some of the side walls.
  • sealing flaps are articulated on two mutually opposite side walls, onto which corresponding wall sections of a lid can be sealed, while side wall tabs articulated on the two other side walls rest on the lid.
  • sealing tabs are articulated on all four side walls, of which at least two opposing sealing tabs have hook-shaped extension tabs which extend beyond the respective side wall and which engage in the region of the adjacent sealing tab when the packaging is erected .
  • hook-shaped extension tabs provide additional hold and a very good seal in the corners.
  • FIG. 1 in FIG. 1 denotes a cardboard blank which has a base 2 on which four side walls 3, 4, 5 and 6 are articulated.
  • the side walls 3 and 4 are connected at their mutually facing narrow side edges by two gusset corners 7 and 8;
  • Corresponding gusset corners 9 and 10 are provided between the side walls 4 and 5, while the gusset corners between the side walls 5 and 6 are denoted by 11 and 12.
  • Corresponding gusset corners 13 and 14 are also provided between the side walls 3 and 6; the gusset corners are each connected by a fold line 15, 16, 17 and 18.
  • the gusset corners 7, 9, 11 and 13 formed on the side walls 3 and 5 are provided with nose-shaped projections 19, 20, 21 and 22 which protrude beyond the respective fold line.
  • sealing tabs 27, 28, 29 and 30 are formed on their longitudinal edge facing away from the bottom 2, of which the two sealing tabs 27 and 29 provided on the side walls 4 and 6 are hook-shaped extension tabs 31, 32 or 33 and 34 have.
  • the gusset corners When erecting the blank 1 to form a bowl-shaped package, the gusset corners are folded around the fold line between them and then placed together on the outside of the two side walls 4 and 6. They cover an area there that is identified by the numbers 23, 24, 25 and 26 is marked.
  • the gusset corners 7, 9, 11 and 13 cover the gusset corners 8, 10, 12 and 14, with only the nose-shaped projections lying directly on the side wall. If only the inside of the cardboard is provided with a sealable plastic layer, when the gusset corners are sealed to the outside of the respective side wall, a seal connection occurs only in the area of the nose-shaped projections. In order to optimize this sealing connection, the areas 23 to 26 can be treated accordingly.
  • the sealing tabs 27, 28, 29 and 30 protrude horizontally outwards when the packaging is erected, as shown in FIG. 2, overlapping in the area of the hook-shaped extension tabs, but without being connected. Only when a lid is sealed is this overlapping area also sealed to one another, as a result of which the corner area becomes very tight and the packaging is additionally stabilized.
  • the cardboard blank 41 in FIG. 4 largely corresponds to the blank according to FIG. 1, only sealing tabs 47 and 49 are hinged to the side walls 4 and 6, and their length corresponds to the length of the respective side wall.
  • a lid 51, as shown in FIG. 5, is expediently used to close a bowl-shaped packaging erected from this cardboard blank 41.
  • This cover 51 has two wall sections 53 within a cover surface 52 which are separated from the rest of the surface by cut lines 54 in the material surface. These wall sections 53 rest on the sealing tabs 47 and 49 and are connected to them by sealing. Two side wall tabs 55 and 56 are articulated to the other two edges of the cover surface 52 and are attached to the side walls 3 and 5 and connected to them. Two perforation lines 57 are arranged in the side wall tab 56, which enable the central portion of this side wall tab and then the inner part of the cover surface 52 to be easily removed along the cutting lines 54.
  • FIG. 6 shows a cardboard blank 61 which has no sealing tabs on the side walls and which otherwise corresponds to the cuts according to FIG. 1 and FIG.
  • a bowl-shaped packaging produced from this blank 61 can be closed, for example, by a slip lid.
