Definitions

  • the invention relates to thermoformed packaging for liquid or solid contents.
  • Thermoforming packaging of this type is known, which is produced from two separate thermoforming foils and is then welded to one another, so that a circumferential seam or circumferential, folded-up edge regions are produced.
  • thermoformed packs are not stable.
  • thermoformed pack in such a way that the stability is achieved.
  • thermoformed packaging is formed in one piece from two thermoformed halves, which form a flat standing surface in their connection area and whose edge surfaces are welded to one another.
  • the packaging shown in the figures is produced as follows:
  • thermoplastic film is thermoformed using the conventional method, which creates the two thermoformed halves 10 and 20. It is essential that two side walls 11 and 21 of the receiving space formed for the contents come to lie parallel to one another after the deep-drawing process with the smallest possible distance.
  • a central web 15 is formed which, after heating, can be shaped in such a way that the two deep-drawn halves, as indicated by the arrow in FIG.
  • the two side walls 11 and 21 then come to lie in one plane and thus form a flat base 30 without seams or other disturbing unevenness.
  • edge areas 12 and 22 are welded laterally to the extent that the thermoformed packaging can still be filled afterwards, the package is then completely welded and punched out.
  • Thermoformed packs of any shape can thereby be produced, the plane running through the central web 15 preferably forming the plane of symmetry of the pack.
