Definitions

  • the invention relates to a folding box made of a folding blank with four longitudinal and side walls connected to a box tube via folding lines and an adhesive flap with hinged lid and bottom closure flaps, which are each formed by longitudinal and side closure flaps.
  • Such folding boxes are used as packaging for powdered goods, for. B. for detergents, used and have glued longitudinal and side closure tabs.
  • this configuration of the longitudinal and side closure tabs requires, on the one hand, a relatively complex manufacturing and, in particular, folding process, for example engaging flaps formed in the side closure flaps are to be inserted accordingly into the cutouts of the longitudinal closure flaps when folded.
  • the folding box parts in particular the longitudinal walls, can migrate out of the cross-sectionally rectangular arrangement, as a result of which the surfaces of the sealing tabs to be glued together can slide out of the intended position, so that no completely tight gluing and also no good bonding Dimensional stability in the head area of the folding box is guaranteed.
  • the object of the invention is to improve the tightness of such folding packaging with simple means and at the same time to keep the packaging in a stable position after filling and gluing.
  • This object is achieved according to the invention with a folding box of the type described in the introduction in that the folding grooves of the longitudinal closure flaps are formed on the inside and the side closure flaps are flared towards their free end for locking in the folding grooves of the longitudinal closure flaps.
  • the degree of the slope of the conical widening is in the range from 0.5 to 10%.
  • this pitch ensures sufficient locking of the side closure flaps even when the folding box is bulging when filling, on the other hand, it is not yet so great that problems could arise when the side closure flaps are folded in.
  • the dimensions and material properties also play a corresponding role.
  • the invention provides in a further development that a relief embossing is formed in the side closure flaps transversely to the corresponding folding groove and the free corner regions of a longitudinal closure flap are each provided with an appropriately designed punched-out area for resting on the relief embossments.
  • This design increases the tightness and dimensional stability of the folding box, since the inner longitudinal closure flap rests on the respective relief embossing of the side closure flaps when it is folded up with each punched-out section, so that an exact positioning of the individual flaps relative to one another is inevitable.
  • FIG. 1 in FIG. 1 denotes a folding blank made of cardboard, corrugated cardboard or the like, which has two longitudinal walls 2, 3 and two side walls 4, 5, which are alternately connected to one another via folding lines 6.
  • an adhesive flap 7 is arranged on the longitudinal wall 2 via a folding groove 6.
  • lid closure tabs are articulated on the longitudinal walls 2, 3 and side walls 4, 5, which consist of longitudinal closure tabs 9, 10 and side closure tabs 11, 12, to be described in more detail.
  • Folding grooves 13 are formed between the side closure flaps 11, 12 and the side walls 4, 5 as usual with an external groove, while internal folding grooves 14 between the longitudinal walls 2, 3 and longitudinal closure flaps 9, 10 have an internal groove, as is particularly well shown in FIG. 3 emerges.
  • the side closure flaps 11, 12 are designed to be locked in the inner folding grooves 14 after folding up towards the free end, the conical extension being denoted by 15.
  • the side closure tabs 11, 12 each have a relief embossing 16 transverse to the folding groove 13. According to the Ausge staltung this relief embossing 16 is formed in the free corner areas 17 of the lying on the side closure tabs longitudinal closure tab when folding a punch 18.
  • bottom locking tabs are formed differently from the lid locking tabs, corresponding parts being identified by the same reference numerals with the additional index "a".
  • the bottom locking tabs are formed by longitudinal locking tabs 9a, 10a and side locking tabs 11a, 12a, the side locking tabs 11a, 12a being arranged via folding grooves 13a and the longitudinal locking tabs 9a, 10a via folding grooves 14a on the respective side walls 4, 5 and longitudinal walls 2, 3.
  • the folding grooves 13a and 14a are conventionally formed with an external groove.
  • the lower side locking tabs 11a, 12a do not have a conical widening, but are rectangular. However, relief embossing 16a is again provided transversely to the respective folding groove 13a. In accordance with the design of these relief embossings 16a, punched-out portions 18a are provided in the corner regions 17a of the longitudinal locking tab 9a.
  • the blank 1 in the folded state being designated as a folding box 20.
  • the four walls 2, 3 and 4, 5 are joined together by appropriate folding around the fold lines 6 to form a box tube by appropriate gluing of the adhesive flap 7.
  • the side closure flaps 11a, 12a are folded in around the folding grooves 13a, whereupon the longitudinal closure flap 9a, which is coated with adhesive at least in the corner regions 17a, is folded around the folding groove 14a against the side closure flaps 11a, 12a, with the flaps being precisely fixed to one another by contact the cutouts 18a to the relief embossments 16a of the side closure tabs 11a, 12a is ensured.
  • the longitudinal closure flap 10a correspondingly coated with adhesive is also folded against the other closure flaps and glued accordingly.
  • the folding box 20 can be filled, the weight of the filler, for example in powder form, ensuring that the bottom closure flaps are completely bonded. Due to the filling, bulging of the folding box 20 can also occur in particular in the lid area 8.
  • the side closure flaps 11, 12 are first folded around the folding grooves 13 in the lid area 8, the side closure flaps 11, 12 engaging in the inner folding grooves 14 of the longitudinal closure flaps 9, 10 due to the conical widening 15 and thus firmly be locked, so that despite the possible bulging of the folding box 20, a stable shape of the lid area 8 is ensured.
  • the longitudinal closure flaps 9, 10, which are coated with adhesive, are then folded in like the longitudinal closure flaps 9a, 10a in the bottom region 19 and glued accordingly.
  • the firm locking of the side closure flaps 11, 12 in the inner folding grooves 14 of the longitudinal closure flaps 9, 10 creates a powder-tight packaging which is also held in a dimensionally stable manner.
  • the dimension of the slope of the conical extension 15 of the side closure tabs 11, 12 is particularly evident from FIG. 3, it being approximately in the range from 0.5 to 10%, so that on the one hand a secure locking in the inner folding grooves 14 is ensured and on the other hand, it is also possible to fold the two closure flaps 11, 12 into the inner folding grooves 14.
  • the invention is not limited to the exemplary embodiments shown in the drawing. Further out configurations of the invention are possible without leaving the basic idea behind.
  • a design of the locking tabs as in the lid area 8 is also provided in the bottom area 19, that is to say side locking tabs with a conical widening and internal folding grooves of the longitudinal locking tabs.
