Definitions

  • Packaging container for e.g. Foods are often marginally by means sealed lid film closed.
  • Such packaging is usually gas and impermeable to moisture, so the food contained therein, under certain circumstances can be kept for a long time without being cooled.
  • containers made of aluminum with a sealed aluminum cover film are due to the excellent barrier properties with regard to gases and moisture tight.
  • the invention is therefore based on the object of a packaging container, in particular for food, and a tear-off lid sealed or glued to the container rim to propose, the packaging container closed with the tear-open lid sealed gas and moisture-tight up to the first opening and after the first opening can be closed one or more times.
  • the object is achieved in that the cover has a tear-open cover a cover film and one on the edge endless or in sections on the cover film attached edge clamping element, and the container edge is an edge surface with a contains the end edge, and the tear-open cover with its cover film on the Edge surface sealed or glued and the edge clamping element with the edge finish a positive and / or non-positive connection is established, the packaging being released the positive and / or non-positive connection between the edge clamping element and the edge termination and tearing the sealing or adhesive seam between the cover film and the edge surface is opened for the first time and the packaging container is replaced by placing the Tear-off lid on the container opening and making the positive and / or non-positive connection one or more times between the edge clamping element and the edge termination can be closed again.
  • a positive connection is made by the shape of the parts, whereby the cohesion by interlocking part contours with or without additional form elements he follows.
  • the release of a positive connection is usually only with effort and usually only possible in preferred directions.
