Definitions

  • the invention relates to a cover sheet according to the preamble of claim 1 for bag, bag or the like.
  • Packaging which has at least one mold bottom to be closed by means of the cover sheet and forming the top or bottom part of the packaging.
  • cover sheets are single-layered. They are glued or sealed on the mold bottom of the packaging, usually a cross-bottom.
  • the invention addresses the problem of providing a topsheet with improved performance characteristics.
  • the invention solves the problem by a cover sheet with the features of claim 1.
  • the cover sheet according to the invention provides an integrated handle which does not affect the handling of the cover sheet in the manufacture of a package nor the handling of the package before and after filling or on transport routes.
  • the cover sheet can also present a pouring opening through which contents can be removed from the filling space of the container.
  • cover sheet 1 which is not part of the invention, is double-layered and comprises an outer layer 2 and an inner layer 3. Both layers 2,3 are interconnected by edge-side seams 4.
  • a handle part 5 is provided, which is formed by spaced cut lines 6, which can be parallel and rectilinear as shown or arcuate.
  • the cover sheet 1 is intended to be mounted on a mold bottom of a package as a closure means.
  • the cover sheet 1 can also be made of plastic film in both layers 2,3 for packaging made of plastic film, wherein suitably strength reasons for the outer layer 2, a plastic film of higher strength is used so that the handle part 5 can fulfill its carrying function properly.
  • a plastic film of higher strength is used so that the handle part 5 can fulfill its carrying function properly.
  • the cover sheet 1 can also be made of paper for paper packaging, wherein the outer layer 2 expediently consists of a reinforcing layer comprising composite material.
  • the reinforcing layer may for example consist of a Tändchengewebe- or glass fiber layer.
  • fiberglass reinforced single-layer paper can be used for the outer layer 2.
  • the connecting seams 4 are designed either as sealing seams or as adhesive seams depending on the material.
  • the two layers 2, 3 of the cover sheet 1 are connected by at least one transverse connecting seam 7, which forms two partial regions 8, 9. With correspondingly firm materials for the layers 2, 3 of the cover sheet 1, such a cross-connection seam 7 is unnecessary.
  • discharge openings 10,11 are provided, which are arranged one above the other.
  • the discharge opening 10 is provided in the inner layer 3 and the discharge opening 11 in the outer layer 2.
  • the discharge openings 10,11 are defined by contour lines 12,13, which may be designed as arc lines and emanate from starting points 14,15, which lie in alignment in the two layers 2,3.
  • the discharge opening 10 in the inner layer 3 is expediently slightly smaller than the discharge opening 11 in the outer layer 2, so that the contour lines 12,13 are mutually covered, which in the interest of avoiding unwanted Gregutaustritt both formed by lines of weakness as well as cutting lines contour lines 12th , 13 is appropriate.
  • the cover sheet 1 according to the invention training with handle part 5 and discharge openings 10,11 forms a quickly and easily manageable with conventional devices unit that does not interfere with handle handling despite the handling of the packaging in their manufacture, filling, storage and transporting.
  • the cover sheet 1 is preferably used in gusseted bags made of plastic or plastic composite film application.
