Definitions

  • the invention relates to a heat-sealable container, the sealing seam of which has a closed contour with a bulge.
  • the contour of the seam is completely continuous, that is to say it is circular in the case of cylindrical containers and square with rounded corners in the case of square or rectangular containers.
  • the amount of force required to tear a sealed seam is proportional to the seam distance to which the force must act.
  • this seam section is particularly large when tapping for the first time - tapping means tearing open the seam to such an extent that a connection is established between the outside and the interior of the container - and becomes increasingly larger with increasing contour. The force for tearing the seam can therefore be a multiple of what is still necessary to tear the torn seam.
  • the object is achieved by a heat-sealable container, the sealing seam of which has a closed contour and the lid of which has a tear tab, which is characterized in that the sealing seam has a bulge at one point, which is formed by two straight seam sections, the two seam sections forming an angle form from 60 ° to 120 °.
  • An angle of 90 °, the apex of which points towards the pull tab, is particularly advantageous.
  • the forces for tearing the seam are introduced into the seam via the apex of the bulge and, in the further course of the opening, only achieve the magnitude of the forces which are required for tearing the completely torn seam.
  • the container 1 with a cantilevered edge 2 is sealed with a lid 3 which has a tear tab 4.
  • Containers and lids are either made of heat-sealable material or are laminated with one if the container and / or lid are made of metal.
  • the sealing seam 5 is provided with a bulge, which is formed by the straight seam sections 6 and 6 a. The apex 7 of the bulge points in the direction of the pull tab 4.
