Definitions

  • the invention relates to a tubular bag, in particular for free-flowing bulk goods, such as Peas, beans, nuts, screws or the like.
  • a tubular bag in particular for free-flowing bulk goods, such as Peas, beans, nuts, screws or the like.
  • the known tubular bags have the disadvantage that they cannot be closed easily after the first opening and therefore the entire content must be removed at once.
  • a tubular bag according to the preamble of claim 1 is known, in which an outer chamber is provided, into which liquid in the tubular bag can enter as soon as it comes under pressure. For emptying, this outer chamber is cut open and the tubular bag is pressurized. A reclosing is not provided and not possible.
  • the invention has for its object to design a tubular bag of the type mentioned so that the removal of a subset and a subsequent reclosing is possible.
  • the fin seam is created on the outside of the bag and by point or the like. Shaped sealing is fixed, and that the sealing surface of the longitudinal seam is provided with a recess coming from the inside of the bag, and that a dividing or perforation line or the like. is provided for opening the bag along the longitudinal seam, which runs within the longitudinal seam and extends into the recess.
  • the bag When a strip of the longitudinal seam is severed along the dividing or perforation line, the bag is only opened in the area of the cutout, but this is completely sufficient to remove a partial quantity of the filling material. By simply pulling the remaining longitudinal seam straight, it is closed again.
  • At least one film section of the longitudinal seam is provided with recesses through which it is possible to seal the inside of the film section with an adjacent film section on the inside or outside thereof.
  • Another advantageous embodiment of the invention also lies in the fact that the longitudinal seam is folded out in a C-shape on the outside of the bag.
  • FIG. 1 denotes a material web which, depending on the intended use, can consist of different materials such as plastic film, paper, cellophane, etc. and is coated in a sealable manner on its later inside.
  • elongated cutouts 3 are punched out one behind the other.
  • the two longitudinal edges are placed on top of one another with their inner sides and sealed together between two boundary lines 4 and 5.
  • the outer boundary line 4 facing the edge of the longitudinal seam strip thus formed has a straight course, while the inner boundary line 5 has a curved course forming a recess 6.
  • this inner boundary line 5 is still guided around the recesses 3 so that no sealing is carried out in their area.
  • a perforation line 7 is also provided within the longitudinal seam, which divides an outer strip-shaped section 8 of the longitudinal seam and thereby runs through the recess 6 formed by the inner boundary line 5.
  • the longitudinal seam strip is then folded into itself in the area of the cutouts 3 and sealed again.
  • the recess 6 remains in a somewhat narrower form, while the two outer layers of the longitudinal seam fold are sealed to one another on their respective inner sides by the punched-out recesses 3.
  • the strip 8 is severed along the perforation line 7, as a result of which the recess 6 is opened and part of the filling material can trickle out.
  • the recess 6 can be closed to such an extent that the filling material does not emerge on its own.
  • a simple marking line can also be provided, along which a corresponding strip 8 is cut off using scissors.
