Definitions

  • the invention relates to a carton for storing bulk material.
  • a folding box for storing bulk material which comprises a Faltschachtelianus.
  • a closure is provided which opens and closes an opening in the Faltschachtelianu.
  • This closure is designed as a click closure and has four pressure surfaces, which are pressed in the direction of the interior of the Faltschachtelianus to convert the click closure in an open position. After releasing the actuating force on the pressure surfaces, the closure closes.

  • a closure for an opening in a carton body is designed as a click closure, which has at least one pressure point and a lid associated therewith, which transfers the lid from a closed position to an open position upon actuation of the pressure point and after releasing an actuating force to this pressure point, the lid automatically returns to the closed position.
  • the closure extends partially along a folding edge between two adjacent side walls of the folding box body and partially in each case in the side walls of the folded box body at least partially.
  • the opening is provided, which are covered by the closure having the side walls.
  • this click closure By means of this click closure, it is possible to apply only an opening pressure to the folding box for opening the folding box for dispensing the bulk material stored therein, and after the desired amount of bulk material has been dispensed, the closure is automatically transferred to the closed position by releasing the pressure point.
  • a click fastener preferably makes it possible to unfold the closure when the pressure point is actuated, wherein an end position of the pressure point in the folding box is not self-holding, so that after releasing the opening force to the pressure point, the independent return to a starting position and thus the cover can be transferred to the closed position is.
  • the lid In this closed position, the lid is preferably provided self-holding.
  • the closure which extends along a folding edge between two side walls and projects at least partially into the two side walls, the restoring force can be generated, which after releasing the actuating force on the pressure point, in particular the fold, an independent reset of the closure in the closing position allows.

  • This has the advantage that the hinged lid can not be pressed into the interior of Faltschachtel stresses in case of incorrect operation.
  • a safe and complete closing of an opening edge of the opening can be made possible by this cover.
  • the contour of the opening deviates from the course of an outer edge of the lid.
