Is on the top of the lid flap 24 which has a upper edge fold line 26 an upper side wall element 30 molded. Adjacent upper side wall elements 30 are over an upper fold line 28 connected to each other and have a width B2 which is essentially the width B1 of the corresponds to the lower side wall element 20. The one in Fig. 1 upper left side wall element 30 is over a fold line 28 formed an adhesive tab 60.
  • the lid folding tab 24 and the connected via the common inner folding line 22 Bending tab 18 have a substantially trapezoidal shape Outer contour, the left outer edge 36 in FIG Bending tab 18 has a slight convex curvature in some areas owns.
  • the distance between the inner fold line 22 and the upper one Edge folding line 26, that is, the height of the lid folding flap 24 is denoted by H1 in Fig. 1.
  • the lower ones are Fold lines 12 and the upper fold lines 28 in one in Fig. 1, imaginary straight line 42 shown in dashed lines arranged.
  • the inner fold line 22 and thus that in FIG. 1 Right outer contour of the cover flap 24 and the illustrated Bending tab 18 is designed so that the distance A of the Beginning of the inner fold line 22 to the imaginary straight line 42 of the Height H1 of the lid folding tab 24 corresponds.
  • the height is to ensure a problem-free unfolding process H1 of the lid folding tab 24 is less than or equal to half Width B2 of the upper side wall element 30 18 has parallel to the inner fold line 22 on the outside arranged embossing lines 32 that the convex Curving process when unfolding the lid folding flaps support inside.
  • the adhesive tabs 38.1 to the in Fig. 1 dashed position with each glued to the adjacent base plate.
  • the upper sidewall elements 30 along their upper edge fold line 26 folded outwards onto the lid folding flaps 24.
  • the folding box 10.1 itself now unfolds in a first step, in which the side wall elements 20, 30 around your fold lines 12, 28 to one in cross section square contour are unfolded (Fig. 3).
  • the bottom flaps 16.1 automatically fold each other in areas behind a closed Ground unit.
  • the Folding box 10.1 from above with the product to be introduced.
  • the folding box 10.1 is closed by is pressed upwards on the upper edge fold lines 26 (Arrows P), whereby the upper side wall elements 30 move downwards, at the same time the bending tabs 18 are convexly curved inwards and thus the Raise lid folding tabs 24 from the inside out, reach behind in areas and in the final state (Fig. 5) one form a closed lid unit.
  • the upper side wall elements 30 with their lower edge area (folded state) jamming on the outside on the lower side wall elements 20 partially pushed on, so that a jammed locked Locked state is given.
  • the upper side wall elements 30 against the clamping effect shifted upwards, causing the Unfold the lid folding tabs 24 and the bending tabs 18 and an opening that is open from above to remove the product arises.
  • FIG. 7 schematically shows another in cross section Design variant shown, in which the height H1 Cover tabs 18 is formed smaller than half of the Width B2 of the upper side wall elements 30. This creates in the folded state, an opening 70 on the top side, so that the introduced product is recognizable from above. It is also possible that the lower side wall elements have a recess in its wall, by through which the introduced product is partially visible is.
