Definitions

  • the innovation relates to a ventable packaging, in particular ventable box-shaped bag packaging for consumer goods, with bag walls formed from film material, which have stiffening folding edges in the longitudinal edge region.
  • Box-shaped packages have the advantage of better visibility of packagings in their gusset area. Apart from that, the box shape also makes it possible to improve the stacking security of filled packages.
  • the invention has for its object to provide a rigid bag packaging with dust-free venting as possible with minimal risk of contamination from the outside through the venting area.
  • the attachment of Absch spazier on partial or, preferably, on the entire length of the package initially has the advantage that a dimensionally stable formation of a bag for receiving filling material, such as flour, fertilizers or the like consumer goods, is achieved.
  • a few millimeters are sufficient, e.g. 2 to 5 mm.
  • air may be expelled from the interior of the bag via the point of passage in the region of the weld seam of a weld. from the interior of the packaging, enter the hollow channel.
  • the ventilation breakthrough in the folded edge which is involved in the formation of the hollow channel, and also belongs to this, the weld with the passage point having Absch spaung, the air entered into the hollow channel then escape to the outside, whereby a venting of the packaging is given.
  • each passage point is a weld break.
  • the weld itself is thereby weakened only slightly, so that they can still meet their actual connection and stiffening function as before.
  • the weld break may be e.g. by suspending the respective welding operation at a predetermined location of the trajectory traversed by a welding head, or else by previously attaching e.g. a release varnish or the like release agent, are generated.
  • the invention is also to be realized if the weld is replaced by an adhesive seam.
  • the adhesive seam may also have passage points, e.g. are made by interrupting the bond.
  • the hollow channel can at its fold, e.g. be opened by means of slotting, punching, perforation or the like at least one point, whereby the folded edge has at least one vent opening in at least one predetermined area.
  • vent openings are preferably offset from the passage points, whereby the passage from the inside to the outside or vice versa is difficult or easier.
  • Fig. 1 shows a view of a ventable box-shaped bag package 1, seen obliquely from below.
  • the sack package 1 for Consumer goods has formed from film material bag walls 2, 3, which have stiffening in the longitudinal edge region folding edges 4, 5, 6, 7.
  • each of the folding edges 4, 5, 6, 7 a Absch wellung with a arranged at a predetermined distance from the respective folded edge 4, 5, 6, 7 weld 8, 9, 10, 11.
  • each of the folding edges 4, 5, 6, 7 a Absch wellung with a arranged at a predetermined distance from the respective folded edge 4, 5, 6, 7 weld 8, 9, 10, 11.
  • Fig. 2 shows a partial view of a longitudinal edge portion of the box-shaped bag package 1 on an enlarged scale and with an outbreak.
  • the weld seam 11 is interrupted, so that a passage point 16 is formed, which is thus located in the area of the weld-off.
  • the interior of the bag is connected in an air-permeable manner to the hollow channel 15 delimited by the folded edge 7 and the weld seam 11, and optionally air can enter the hollow channel 15 from the bag interior.
  • the folded edge 7 has in a predetermined area a vent opening 17, which also in Fig. 1 is visible.
  • the box-shaped bag package 1 is formed via each passage point 16 and each of the vent opening 17 vented.
