Definitions

  • the present invention relates to packaging, in particular for containing food a packaging container with a container edge surrounding the container opening and a tear-open lid applied over the container opening, and a method for Production of a packaging according to the invention with a tear-open cover.
  • 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.
  • animal feed is placed in aluminum containers sealed with aluminum cover foils offered in stores. Often those are contained in such packaging Portions not at once, but within two or more days within one or more days or used several times.
  • such packaging cannot appropriately reclosed, the content dries out and unpleasant spread Smells. There is also a risk that the contents of the package spoil quickly.
  • the invention is therefore based on the object of a packaging container, in particular for food, and a tear-off lid detachably attached 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 or should be closable several times.
  • the object is achieved in that the tear-open cover is made of a cover film and one at the edge endlessly or in sections to form a detachable one or non-releasable connection zone attached to the cover sheet edge clamping element exists, and the container edge contains an edge surface with an end edge termination, and the tear-open cover with its cover film and / or with the edge clamping element underneath Forming a releasable connecting seam on the edge surface is fixed and the edge clamping element a positive and / or non-positive connection is established with the edge closure, wherein the packaging by loosening the positive and / or non-positive connection between Edge clamping element and edge termination and tearing of the detachable connecting seam is opened for the first time on the edge surface and the packaging container is opened again Place the tear-open lid on the container opening and manufacture the shape and / or Non-positive connection between the edge clamping element and the edge termination or can be closed again several times.

  • the peelable or tearable connection seam serves to open the package and the separation of packaging container and tear-open lid as non-destructively as possible the preferably non-tearable connection zone, especially during the first opening should not be separated.
  • clamps there is in particular a releasable positive and / or non-positive connection between the edge clamping element and the edge termination, which is preferably without additional fasteners.
  • 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.

  • Externally acting Forces such as frictional forces or other field forces on the component effective surfaces, which e.g. by elastic or elastic-plastic component or connecting element deformations (Hook forces) are applied.
  • the release of a frictional connection is in the Usually only by generating corresponding counterforces or by lifting the effective ones Powers possible.
  • connection is between Edge clamping element and edge termination by a combination of the two aforementioned Connection types, i.e. a so-called positive connection.
  • the positive and / or non-positive connection are e.g. by a bracket or Pliers, clip or tension effect or a combination of these causes these effects can be achieved with materials with elastic behavior, among other things.
