Definitions

  • the invention relates to bags made of film with the features of the preamble of claim 1 such as from EP 005541 known.
  • the bags in question serve in particular for receiving a portion of cut tobacco.
  • a one-piece (foil) blank by folding it forms a pocket with pocket front panel and pocket back panel for receiving the bag contents.
  • the pocket is bounded laterally by seam-stitching seams.
  • a filling and removal opening is usually provided with a sealing seam.
  • a closure flap which is foldable against the pocket front wall, folded in the embodiment as a wrap around the bag and fixed to the pocket rear wall.
  • the invention relates to an improved version of such bags.
  • the locking tab in particular the winding tab, is provided with a one-piece extension, which is folded as a leg against the inside of the locking tab or winding tab and this covers.
  • the closure tab or pocket is so double-layered with an outer layer and an inner layer.
  • the two layers of the closing flap are connected to each other by lateral (sealing) seams - tab seams - and by a connecting seam.
  • the closure flap thus created has an increased dimensional stability and, moreover, a printable or printed outer width of the film is visible on the inside of the closure flap.
  • the invention has for its object to improve the bag of the above embodiment in terms of design education.
  • the bag according to the invention with the features of the characterizing part of claim 1 is formed.
  • a special feature of the bag is therefore that the layers of the closure or winding strap are connected to a hot-melt seam. It is advantageous at least one further connection of the layers of the closure or winding strap by hot-melt in a central region.
  • at least one preferably slot-shaped opening in the inner flap is attached, which - preferably in conjunction with a hot-melt seam - increases the stability of the (Wikkel-) tab and in particular prevents the deformation of corners of the tab.
  • the bag 10 consists of a pocket 11 and a closing tab 12.
  • the pocket 11 receives the bag contents, in particular a portion 13 of cut tobacco.
  • the bag 10 preferably consists of a single, elongate, rectangular blank of the film. By folding along a (lower) folding edge 14, the pocket 11 with pocket front wall 15 and pocket rear wall 16 is formed. These are connected to one another laterally by (transverse) pocket seams 17, 18, the pocket seams 17, 18 preferably being produced by thermal sealing are.
  • the bag 11 has a pocket opening 19, which allows the filling and removal of the bag contents.
  • the pocket opening 19 is closed by a transverse sealing seam 20.
  • this is designed as (reusable) peel-seal seam.
  • the pocket rear wall 16 is extended beyond the pocket opening 17 and forms the closure tab 12. This is folded against the pocket front wall 15 and fixed in the closed position with an adhesive strip or a tape 21.

  • the free (inner) side of the inner layer 23 is provided with decorative and / or informative printing 30.
  • the inner layer 23 rests against the pocket front wall 15 and preferably at least partially against the pocket rear wall 16 and is fixed by means of tape 21.
  • the layers of the closure tab 12 are - in particular in addition to the connecting seam 27 - provided with further connections to stabilize the tab 12.
  • Another connecting seam namely an intermediate seam 31, is arranged between the two layers 22 and 23, in the embodiment as a hot-melt connection.
  • the intermediate seam 31 runs parallel to the connecting seam 27 and is arranged at a smaller distance from the tab edge 24, and likewise terminates at a distance from the two flap seams 25, 26.
  • closure tab 12 is provided in the region of the inner layer 23 with an opening.
