Definitions

  • thermoplastlc material havlng a rear wall R 226/48 R 29/48 with an articulated lid and closure flap, two side walls, [51] Int Cl B65d 5/22 and a front wall, the side and upper edges of the side [58] w T 48 R walls and the upper edge of the front wall being bent outwardly to form closure borders.
  • Folding boxes intended to be suitable for storing deep-frozen products must possess a whole series of properties. These include, above all, absolute fluidtightness and hence extremely good adhesion at the points of welding. This, in turn, can be achieved only if coated surfaces face each other at all points of welding, and if a sufficient amount of pressure can be applied, which is not always possible when the welding tongs cannot grasp from both sides the two folded portions to be welded.
  • a further prerequisite for the utility of a folding box serving to store deep-frozen products is the absence of multiple layers at the pointsof welding, for these always lead to leakage. Furthermore, no raw-cut edges may extend into the interior of the box since otherwise, if the packaged product partially thaws, the liquid can penetrate into the material at the cuts and discolor it.
  • the folding box must have a certain stiffness and lend itself to being machine-made in a simple manner.
  • the invented folding box is characterized in that the side edges of the side walls and the upper edges of the side and front walls have outwardly bent closure borders which, when the box is closed, are joined to the inner sides of the rear wall and front wall DESCRIPTION OF THE DRAWINQ DESCRIPTION OF THE PREFERRED EMBODIMENT
  • the box according to the invention is set up from a blank coated on one side with a conventional heatsealable material, the coated surfaces being on the inside when the box is set up.
  • the box has a bottom 1, from which the rear wall 2, the two side walls 3 and 4, and the front wall 5 are folded upward, the lid 6 with the closure flap 7 being articulated to rear wall 2.
  • Another closure flap 8 is provided on front wall 5.
  • closure borders 9-14 The upper edge and the two side edges of side walls 3 and 4 are bent outward at a 90 angle to form closure borders 9-14, so that the coated surfaces of lateral closure borders 11-14 lie against the inner sides of front wall 5 and rear wall 2, respectively, and make possible a faultless weld.
  • the closed box is absolutely fluid-tight since the coated surfaces are against each other at all points of welding, multiple layers do not occur anywhere, and, because the closure borders to be welded project outward, they can be grasped from both sides by the welding tongs and welded under comparatively high pressure.
  • this box has no raw-cut edges extending into its interior; and the bent-out closure borders of the side portions form an additional stiffening which not only increases the stacking possibilities but also allows the use of a comparatively light cardboard.
  • a folding box set up from a blank coated on one side with a heat-scalable material having a rear wall with an articulated lid and closure flap, two side walls and a front wall, the side edges of the side walls and the upper edges of the side walls and front wall being bent outwardly to form closure borders which, when the box is closed, are joined to the inner sides of the front and rear walls and to the underside of the cover, respectively.
