Definitions

  • the invention relates to a packaging container according to the preamble of the main claim.
  • a packaging container is known from DE-OS 25 37 317, in which, in order to avoid bursting of the sealed container, gas emitted by the filling material, for example coffee, through one or more openings in the wall of the container and through the latter covering it Pressure relief valve can escape. Since such valves are very sensitive to dust and their function can be impaired by the contents of the filling material entrained in the escaping gas, the passage in the known container is designed in the form of several holes with a small cross section or with egg a piece of filter paper covered.
  • the packaging container according to the invention with the characterizing feature of the main claim has the advantage that the slot can be cut with a simple, bevelled, for example cylindrical stamp on its end face. It has a particularly advantageous effect that the flap delimited by the slot can spring back or be pushed back into the plane of the container wall, so that the width of the slot is less than 0.05 mm, but due to the length of the slot a sufficiently large passage cross section is given for escaping gas. As a result, the gas flow rate is low and the filter effect is very high.
  • the measures listed in the subclaims enable advantageous developments and improvements of the packaging container specified in the main claim.
  • the formation of the slot as a semicircular arc is particularly advantageous since the resilience of the cutting area is greatest in this shape.
  • FIG. 1 shows a bag pack in a diagrammatic representation
  • FIG. 2 shows part of the wall of the bag pack with a pressure relief valve in cross section in the plane II-II of FIG. 1 on an enlarged scale.
  • a bag.1 made of a flexible packaging material contains a gas-releasing material, for example ground coffee.
  • a gas-releasing material for example ground coffee.
  • the pressure relief valve 5 consists of a rigid base plate 6 with a perforation 7 in register with the opening 3 in the wall 2 and from a flexible membrane 8, which valve channels 9 is partially glued to the base plate 6.
  • the opening 3 in the wall 2 of the bag 1 has the shape of an arcuate slot 10, the gap width of which is less than 0.05 mm.
  • the slot 10 preferably has the shape of a semicircle with a radius of 1 to 2 mm.
  • the slot 10 is cut into the wall 2 of the bag with a cylindrical stamp with a beveled face.
  • the semicircular region bent out of the plane of the wall 2 springs back into the original position due to the restoring force of the packaging material, or is pressed back into the plane of the wall 2 by pressing means.
  • the slot 10 can be cut into the packaging material before removing a container is shaped, but it can also be attached to the container before it is filled.
  • the pressure relief valve 5 is glued to the outside of the bag 1 in register with the slot 10 after cutting the slot.
  • the slot is in the form of an arc of a circle which delimits a flap which, due to its continuous connection to the container wall, springs back into the plane of the wall after being cut free, so that the slot is very narrow. This is also achieved with, for example, an angular or undulating or, generally speaking, with a non-straight slot.
