Definitions

  • the invention relates to a packaging bag by flat Material is formed that at least once after at least one edge folded over and sealed on at least one other edge is connected, and in which there is a tear notch on one edge is.
  • Figures 3 to 7 show cross sections through some known types of packaging bags.
  • a hose is formed.
  • This tube can be made by welding a longitudinal sealed seam be as shown in Figures 3 to 5, or it can be seamless like that Show examples according to Figures 6 and 7.
  • the hose then becomes Cutting, attaching a first cross seal, filling and attaching one second cross-sealed seam, the packaging bag completed. It can the order of the last four working steps varies almost arbitrarily except that, of course, the attachment of the second cross seal seam must be done after filling.
  • Notches as a tear-open aid in the shape of, for example, a triangular one or rectangular notch, can be on any sealed edge such packaging bags are attached. Can on folded edges but no notch should be made, otherwise the bag would leak.
  • packaging bags of the type mentioned are designed in this way and labeled that there is a cross seal seam at the top and bottom and that a single longitudinal sealed seam in the back surface of the bag is arranged.
  • a tear-open notch on the longitudinal sealing seam would be for the user impractical and difficult to discover. So it remains with bags this type practically only the possibility of tearing notches on the edge of the top Apply cross-seal seam.
  • Such Bags often too small or too large openings, which is particularly that means liquid or granular or powdered bag contents very much can be uncomfortable.
  • the invention lies The task is to propose a packaging bag that is folded over on a Edge has a tear notch and is still completely tight.
  • the Tear notch is arranged on an edge on which the flat material is folded inwards and that the bag material in one is the tear notch surrounding area is tightly sealed.
  • This solution according to the invention increases in particular the freedom of design in the production of packaging bags by a Tear notch regardless of the location of the sealing seams at any point a folded edge of the bag can be attached.
  • Figure 1 is a perspective view of the corner area of a so-called Gusseted bag.
  • These are packaging bags where the lateral areas are folded inwards so that they are approximately M-shaped in cross section appearance.
  • Figures 5 and 7 show schematic cross sections of such Bags, preferably made up of sections of a tubular Material 7, for example a plastic film, are made. Any such The bag has two edges 3 on each side, on which the bag material follows is folded inside. In between there is a point 9 at which the bag material is folded outwards.
  • the hose is formed by a longitudinal sealing seam 8; the example according to figure 6 consists of a hose without a longitudinal seam.
  • Figures 3, 4 and 6 relate to relatively flat packaging bags without M-shaped side edges.
  • the embodiment of Figure 3 is rarely seen because it looks asymmetrical. That is why the longitudinal sealing seam 8 preferably laid in the rear surface of the packaging bag, as can be seen in FIGS. 4 and 5.
  • Packaging bags of the type shown in Figure 1 are often included bulk goods such as liquids, powders or granules. With such goods, of course, the packaging should be torn open can without their content accidentally escaping, i.e. roughly parallel to the upper one Cross seal seam 2. This is made possible by the edge 3 near the upper cross-sealing seam 2 a tear notch 4 is arranged, the Bag material sealed in a region 5 surrounding the tear-open notch 4 is so that the content does not leak through the tear notch can.
  • the area 5 can directly surround and has the tear-open notch 4 preferably the shape of a segment of a circle, particularly preferably one Semicircle.
  • the two tear-open notches 4 are equidistant from the upper transverse sealing seam 2 removed.
  • the edges 3 in the upper area can be compressed so that the two tear notches 4 lie exactly one above the other.
  • the crack reaches point 9.
  • you can of course 3 tear-open notches can also be provided on the opposite edge, so that the bag can be torn open from two sides.
  • the embodiment according to FIG. 2 largely corresponds to that according to FIG. 1, only that here the sealed area 6 has the tear notch 4 in surrounds a distance. With certain bag materials 7, such a distance be beneficial.
  • the area 6 then preferably has the shape of a Circular ring segment and particularly preferably the shape of a half circular ring.
  • the tear notches according to the invention with known means such as slit bands or lines of weakness, the were generated by scratching or by means of a laser to support a straight course of the crack.
