Definitions

  • the invention relates to a cardboard box or the like. for bulk goods, with a removal opening which is closed with a closure part which can be at least partially separated from a wall of the folding box along a predetermined breaking line.
  • a large number of folding boxes designed in this way are known; they can all be opened more or less easily, but can hardly be reclosed to some extent.
  • the invention has for its object to design a folding box of the type mentioned so that a relatively tight reclosure is possible.
  • closure part is arranged at a point on the folding box at which the wall is double-layered, and that a closure part is provided both in the inner and in the outer position of the wall, which are intimately connected .
  • the closure part arranged in the outer wall position is articulatedly connected to it in the open state, while the closure part provided in the inner wall position is completely separated from it.
  • the closure part provided in the inner wall position has at least one section with a relatively small radius of curvature.
  • At least two adjacent corner regions of the inner closure part are provided with a relatively small radius of curvature.
  • the outer closure part completely covers the opening in the inner wall layer which arises when the inner closure part is removed.
  • closure parts are arranged in the region of a corner of the folding box, and that at least the boundary edge of the outer closing part facing the corner of the folding box is rounded.
  • the detectability of the outer closure part is further improved if, according to a further embodiment of the invention, the sections of the outer wall layer adjacent to the outer closure part and facing the corner of the folding box are at least slightly withdrawn from the corner.
  • a dust flap is provided in the region of the wall sections carrying the closure parts, which has a recess corresponding to the size of at least the inner closure part.
  • the dust flap in no way hinders the free escape of the filling material through the closure opening.
  • a carton blank 1 shown in FIG. 1 has a front wall 2 and a rear wall 3, which are connected to one another via a side wall 4.
  • a further side wall 5 is deflected, which can be glued or sealed when the cardboard blank 1 is erected into a folding box with a connecting strip 6 articulated on the rear wall 3.
  • a bottom flap 7,8 is articulated on the front and rear wall, while the two side walls carry dust flaps 9 and 10.
  • the edge of the front wall 2 opposite the bottom flap 7 carries an outer cover wall 11, while an inner cover wall 12 is articulated on the rear wall 3. Dust flaps 13 and 14 are also provided on the two side walls 4 and 5 at this end.
  • a closure part 16 is separated from the outer wall 11 by two perforation lines 15, which can be separated along these perforation lines 15 and remains connected to the wall along a fold line 17.
  • a closure part 18 which is delimited by a perforation line 19 along which the closure part 18 can be separated from the wall 12.
  • the closure part 16 is grasped and detached from the wall 11 along the perforation lines 15 to such an extent that it can be folded upwards.
  • the closure member 16 is grasped and detached from the wall 11 along the perforation lines 15 to such an extent that it can be folded upwards.
  • the inner closure part 18 snaps into the opening in the inner wall 12 and is held there sufficiently due to the narrow radii to ensure secure reclosure. Due to the larger configuration of the outer closure part 16, the perforation line 19 is securely covered, which further increases the tightness.
  • a cover wall 31 is articulated to the front wall 2 of the cardboard blank 30, in which a closure part 36 is delimited by two perforation lines 35 and a fold line 37.
  • a further closure part 38 is provided which is delimited by a circumferential perforation line 39. Two corners with a relatively small radius of curvature are formed in the course of this perforation line 39.
  • a further dust flap 33 is articulated on the side wall 4 and is provided with a recess 40 which, when the blank 30 is erected to the folding box 41, is brought into register with the two closure parts 36 and 38.
