Definitions

  • the invention relates to a film bag made of two flat, mutually flat, essentially rectangular film layers, which are closed on three side edges of the film layers connecting folding, welding or adhesive lines and on a side edge, preferably arranged on a narrow side, forming an insertion opening for Documents or the like is open, and the side edge perpendicular to the open side edge preferably has a reinforcing insert, has an inner weld or adhesive seam that delimits the inside of the pocket and an outer edge that is essentially parallel to the outer edge and has a defined width, the inner sweat - or adhesive seam of the edge strip along an inclined path near its insert-side end has a funnel-like course which widens the inside of the pocket towards the insertion opening and is at an acute angle to the outer edge.
  • One-sided open film pockets of this type can be hung in a folder or in a ring binder with the row of holes arranged in their edge strip. They are therefore particularly suitable as brochure or document covers. If the width of the edge strip and thus the width of the pocket interior is constant over the entire pocket height and essentially corresponds to the DIN dimensions of the writing material, the insertion of the often pliable writing material into the insertion opening presents certain difficulties.
  • the object of the invention is to improve the known film pouch of the type specified at the outset in such a way that the insertion of documents through the insertion opening is facilitated.
  • the invention is based on the idea that the written material can be introduced more easily into the film pocket if the inclined section runs in a straight line and is 1.5 to 3 times as long as the width of the edge strip and if the acute angle between the inclined section and the outer edge 10 ° to 25 °.
  • the document obliquely into the insertion opening over a sufficient insertion distance before it is completely inserted into the pocket in a parallel orientation.
  • the inclined section of the inner weld or adhesive seam expediently extends into the vicinity of an insert-side hole in the row of holes. It is particularly advantageous if the oblique distance of the inner weld or adhesive seam extends up to a distance approximately corresponding to the width of the edge strip to the insertion-side hole of the row of holes.
  • a further improvement in the insertion behavior can be achieved in that the edge strip is rounded at its end on the insertion side.
  • the outer edge of the edge strip is advantageously also formed by a welded or glued seam.
  • a preferred embodiment of the invention provides that the inner weld or glue seam and the outer edge designed as a weld or glue seam limit an edge welt pocket for receiving the reinforcing insert, the inner and outer weld or glue seam on the front side being formed by convexly rounded connecting seams to form a closed edge welt pocket can be connected.
  • Another relief when introducing documents is achieved in that one of the film layers in the region of its edge edge delimiting the insertion opening has a recess which is open at the edge and extends into the vicinity of the inclined distance of the inner weld or adhesive seam.
  • the film bag shown in the drawing consists of two essentially rectangular, flat sheet layers 10 lying flat against each other, which are integrally connected to one another at a folded edge to form a closed longitudinal side edge 12.
  • the border strip pocket contains a reinforcement strip 24 made of flat material and a series of continuous round holes 26 for filing the film pocket in a folder or ring binder.
  • the film layers 10 are connected to one another by a simple weld seam, while at their upper narrow side edge 30 they are not connected to one another to form an insertion opening for documents.
  • the inner weld seam 16 of the edge strip 14 near its insert-side end along an inclined path 32 has a funnel-like course which widens the pocket towards the insertion opening 30 and is at an acute angle to the outer weld seam 18.
  • the acute angle ⁇ is approximately 15 °
  • the inclined section is approximately twice as long as the width b of the edge strip.
  • the edge strip 14 decreases along the inclined section 32 to the end on the insertion side to approximately half its maximum width b.
  • the inclined section 32 of the inner weld 16 extends up to a distance a approximately corresponding to the edge strip width b to the insertion-side hole 26 ′ of the row of holes 26.
  • the rear film layer according to FIGS. 1 and 2 has in the region of its edge 30 which delimits the insertion opening an open edge 34 which extends into the vicinity of the inclined section 32 of the inner weld seam 16.
  • Both the film layers 10 and the reinforcing strips 24 are suitably made of polypropylene.
  • the invention relates to a film pocket consisting of two film layers 10 lying flat against one another and essentially rectangular in outline.
  • the film pocket is closed on three side edges 12, 14, 28 by folding, welding or adhesive lines or seams and open at one side edge 30 to form an insertion opening for documents.
  • an edge strip 14 with a defined width is arranged on a side edge 18 perpendicular to the open side edge 30.
  • the inner weld seam 16 of the edge strip 14 in the vicinity of its insert-side end 22 has a funnel-like course which widens the inside of the pocket towards the insertion opening and is at an acute angle to the outer edge 18.
