Definitions

  • the invention relates to a cuboid pack, in particular cigarette pack, with outer wrapping made of foil and with a attached to the outer sheath, finite tear thread or a line of weakness. Furthermore, the invention relates to a method and an apparatus for producing packaging material formed in the above manner.
  • Packages of different shape and design are often provided to protect the contents of the package with an outer wrapper made of film or a similar packaging material.
  • an outer wrapper made of film or a similar packaging material.
  • this is often provided with a tear thread or tear strip, which is attached by gluing or sealing to the outer sheath. This can be severed by detecting the tear thread at a handle end and so eliminated.
  • the invention relates to such packages, in particular with cigarette packs in the execution as cuboid hard pack (made of thin cardboard).
  • the invention is based on the object, a tear thread or the weakening line or tear strip on the outer sheath of a pack to be mounted so that upon actuation of the tear thread or the weakening line, the outer sheath is reliably removed in its entirety.
  • the package according to the invention is characterized in that the tear thread or the weakening line in the region of a large front wall and / or rear wall obliquely or approximately diagonally extends from a (lower) Packungsecke to a diagonally opposite (upper) Packungsecke.
  • the (approximately) diagonal course of the tear thread or the weakening line in the area of at least one of the large-area packing walls ensures that the outer wrapper is optimally severed the first time so that the remaining wrapper parts can be pulled off in a simple manner via packing corners.
  • the invention is particularly suitable for cigarette packs of the type folding box with shrink film as outer sheath.
  • a special feature is the weakening line of the outside envelope formed as a foil or the like. This forms a weakening of the wall thickness of the packaging material while maintaining the tightness. In the area of the linear material weakening, the film can be easily cut through. Alternatively, this may be a double line, that is, two parallel lines of weakness defining a detachable strip of material of the film, or a single line of weakness that can be severed by hand upon opening the enclosure.
  • the tear thread or the weakening line is arranged so that in the region of narrow, upright side surfaces, a transversely directed, rectilinear portion is formed, adjacent to an end wall on the one hand and to a bottom wall on the other hand, and that these sections respectively rectified diagonal portions of the front wall and Connect rear wall together.
  • a special feature is the production of a (film) web with continuous tear thread or tear strip or continuous weakening line as well as blanks for outer sheaths.
  • the tear thread or tear strip or line of weakness during continuous transport of the web of film, paper or the like is applied thereto, wherein the tear thread is moved by an exactly controlled thread guide according to the thread configuration to be produced transversely to the conveying direction of the (film) web ,
  • thread sections ie finished tear strip or tear strip with respect to the shape and length applied to the continuous (film) web.
  • the tear strips are separated by a contoured cut of a thread path and thereby placed directly on the track according to the position of a blank for the outer sheath.
  • the inventive device for applying a continuous tear thread or tear strip on a continuously moving web has a special guide member for the tear thread, namely with a guide roller.
  • This has a double function, namely serves for applying the tear thread to the web and at the same time as a management body.
  • the guide roller is moved by a controlled gear in the direction transverse to the web or transverse to the conveying direction thereof, so that the tear thread is transmitted in a curved configuration on the web.
  • the drive of the tearing thread drawn from a thread bobbin is controlled taking into account the relative movement between the preferably continuously and at a uniform speed promoted web on the one hand and the tear thread on the other hand.
  • the device according to the invention for applying contoured thread sections or finished tear thread has a contoured, namely curved separating knife, which at each working cycle during instantaneous standstill of the web or a web section separates a tear thread formed according to the invention from a yarn path fed in the transverse direction and positionally accurate applies to the (film) web, in the region of a blank to be separated from this.
