Definitions

  • the invention relates to a tetrahedral packaging bag from a flexible film material and a method for producing the packaging bag.
  • tetrahedral bags made of plastic coated Cardboard for drinks known.
  • the packaging bag For the beverage withdrawal is the packaging bag at one point, for example, with one of a film sealed Opening provided that can be pierced by means of a drinking straw.
  • Other bags may form a spout along a perforation line be torn up.
  • tetrahedral packaging bag a flexible film material for coated with a sugar masspinstraagees known. For opening, as with many pouches, one in a sealing seam arranged Anr exertkerbe.
  • the invention is based on the object, a packaging bag of the above mentioned type, with the liquid and free-flowing solid ingredients dosed over a defined opening can be removed.
  • a packaging bag of the above mentioned type with the liquid and free-flowing solid ingredients dosed over a defined opening can be removed.
  • the Packaging bag should be easy to make and can offer a simple reclosure system.
  • the tubular Spout in pouring direction away from the tetrahedral corner of the bag is conically tapered.
  • the conical design of the Spout has the advantage that, for example, when opening with a pair of scissors the cross section of the by cutting away the closed end of the Spout part transverse to the spout emerging spout opening with increasing Distance of the cut from the free end of the spout larger becomes. In this way, a suitable for a specific purpose dosing be set individually.
  • the spout for providing dosing with different Cross section at least two at different distances to the closed arranged tearing notches arranged free end of the spout can.
  • can In addition to the tear score lines of weakness are provided. The lines of weakness go from the top of the tear scores and revolve around the spout part.
  • the invention projecting from a tetrahedral corner of the bag spout part can with unopened packaging bag, for example, against a the bag surfaces folded back and by means of a on the bag surface or on Spout arranged pressure-sensitive adhesive are fixed in the folded position.
  • unopened packaging bag for example, against a the bag surfaces folded back and by means of a on the bag surface or on Spout arranged pressure-sensitive adhesive are fixed in the folded position.
  • the spout during transport and storage of the Packaging bag relatively well protected against mechanical damage.
  • After opening the packaging bag by cutting the spout in the region of its free end results from a suitable arrangement of the pressure-sensitive adhesive in conjunction with the folding or Faltbärkeit of the pouring part an easy way to close the opened bag again.
  • This simple closure can, at least for free-flowing solid bulk materials Leakage of the contents effectively prevented when the package is overturned become.
  • the inventive packaging bag As a beverage bag, it may prove to be useful in the spout Stiffening element, preferably a piece of plastic pipe to order.

  • the germ-free pipe section is exposed and can be brought directly to the mouth without touching.
  • the object is achieved according to the invention, that of a band-shaped film over a longitudinal sealing seam a hose and from the tube through a transversely arranged to the longitudinal sealing seam first Transverse seam and a transverse to the longitudinal sealing seam and substantially perpendicular and arranged at a distance from the first transverse sealing seam second transverse seam the tetrahedral packaging bag is formed, wherein one of Transverse sealing seams are placed in the region of a tetrahedral corner of the bag so that is a substantially tubular, protruding from the bag and on its free end closed pouring part arises.
  • the transverse sealing seam is placed so that one pointing away from the bag Outlet direction conically tapered spout arises.
  • the pouring part at least one tearing notch extending transversely to the pouring direction to be ordered.
  • the pouring or dosing openings with different size opening cross section are expediently at least two at different distances from the closed one arranged tearing notches arranged free end of the spout.
  • the spout part circumferential Lines of weakness are arranged.
