  • the cartonlOO may be formed from any embodiment of the above-described carton blank 10, where the carton blank is forming a carton by folding the blank into a tube comprising the rear panel 12, the right panel 14, the left panel 16 and the front panel 18.
  • One of these panels 12, 14, 16, 18, not being connected to two neighboring panels is attached to another one of the panels not being connected to two neighboring panels by means of a glue flap 62 extending from one of these two panels.
  • the glue flap 62 is arranged to attach the rear panel 12 to the right panel 14.
  • the bottom of the carton 100 may in some embodiments be formed by the two bottom closure flaps 24, 26, the inner bottom panel 20 and the outer bottom panel 22.
  • the bottom closure flaps 24, 26 may be shorter panels folded into a position where they each seal an edge, e.g. the right hand bottom edge and the left hand bottom edge, between one of the walls of the carton and the bottom.
  • the inner bottom panel 20 and the outer bottom panel 22 may be folded after the bottom closure flaps 24, 26 and be attached to each other two create a firm bottom of the carton 100.
  • the inner bottom panel 20 is folded first and then the outer bottom panel 22 is folded into contact with the surface 52 of the inner bottom panel 20.
  • This position of the inner bottom panel 20 in relation to the outer bottom panel 22 may be fixed by providing adhesive between the two panels. Further, the surface of the two bottom closure flaps 24, 26, may also be attached to both or at least one of the inner bottom panel 20 or the outer bottom panel, e.g. by using a suitable adhesive.
  • the top of the carton 100 is formed by each of the dust flaps 40, 42, being folded towards each other, then the top closure panel 36 is folded over the dust flaps 40, 42 and the top tuck flap 56 is folded and inserted at a position between the inner surface of the front panel 18 and edges of the dust panels 40,42.
  • the outer top closure panel 38 is then folded onto the outer surface of the top closure panel 36 and fixed to the top closure panel 36 by means of adhesive.
  • the top closure panel 36 is also fixed to the two dust flaps 40, 42, by means of adhesive 102, the adhesive 102 being arranged in the area of each dust flap 40, 42, coinciding with the hatched area 54.
  • the hatch pattern 54 may be positioned to cover a central portion of each of the dust flaps 40, 42, central in respect of the direction of the right and left top edges 48, 50, respectively.
  • the area hatched 54 may have a width, i.e. a length in a direction perpendicular to the corresponding left or right top edge 48, 50, that is at least 50% of the width of the corresponding dust flap 40, 42.
  • the length of the hatched area is substantially the full length of the dust flap 40, 42, with some margins at each end, e.g. the length may correspond to at least 90% of the length of the corresponding top edge 48, 50.
  • the adhesive is arranged on the hatched area and as a result of the positioning on the dust flaps 40, 42, attachment to the top closure panel 36 it will be very difficult, if not even impossible, to access the interior of the carton 100 and remove and or tamper with items placed in the carton 100 without tearing the hatched surface of the dust flaps 40, 42, from the base structure of the dust flaps 40, 42, and thereby leaving a clearly visible indication that the carton has been tampered with.
  • this arrangement also facilitates the opening of the carton 100, because the hatched surface 54 of the dust flaps 40, 42 will detach from the base structure of the carton more easily if the adhesive 102 for example is aggressively attached to the surfaces of the cartoon.
  • the hatching helps to make the adhesive 102 stick to a surface that otherwise may be difficult to have the adhesive stick to.
  • the adhesive used may be any type of adhesive normally used in the making of cartons, e.g. hot glue, white glue, tape, etc.
  • the positioning and the extent of the area hatched 54 may, as discussed above, vary. However, the positioning and extend should at least be covering such an area that it makes it difficult, even impossible, for someone to access the interior of the carton 100 and remove items without tearing away the hatched area on a dust flap 40,42.
  • Another advantage of the fixing the dust flaps 40, 42, to the top closure panel 36 as discussed above is that the top closure panel stay close to the top edge of the carton 100 and do not arc leaving an opening into the carton 100. The arrangement will also secure items in the cartons during transport.
  • Another advantage is that the above discussed embodiments of the carton, with all the advantages to integrity and security of the carton and the items provided in the carton, still is easy to open for a user.
  • the top closure panel 36 retain the top tuck flap 56 during an opening operation of the carton and thereby the carton will be reclosable after the carton has been opened the first time, even after breaking all the bonds arranged to fixedly arrange the top closure arrangement for transport and for avoiding unnoticed access of the interior of the carton.
  • the outer top closure panel 38 may still be attached to the top closure panel 36 at the end where the top tuck flap 56 extends from the top closure panel and the outer top closure panel 38 may thereby reinforce that edge of the top closure panel 36 and facilitating the reclosure of the top closure panel.
  • the embodiment depicted in the figures is provided with side panels 14, 16 that each is longer in the top edge direction than the length of any one of the rear panel 12 and the front panel 14 in corresponding top edge direction. Cartons formed like this are prone to tampering or theft of the goods from the interior of the carton.
