  • packagings have preferably been produced from a film and / or laminate material which, because of its low weight, flexibility and good sealability, is suitable for producing these packagings.
  • tubular packaging i. As a rule, round packages are preferred because they require a minimum of laminate for wrapping in relation to the packaged volume.
  • the object of the invention is to solve the aforementioned problems and to provide a tubular, in particular can-shaped container available, which is easy and inexpensive to manufacture from a variety of available materials and a maximum of volume compensation, both in over- and at Allows negative pressure in the container, which has a sufficient stability against the Greguta and beyond is reversible resettable with respect to the contents of the product.
  • the object is achieved by a tubular, in particular can-shaped, container for holding fluids, in particular drinks, pastes and pourable or pourable goods, with a tubular body and attached to this bottom and / or lid, the bottom and / or gege- If necessary, the lid are each designed conically or pyramid-shaped projecting into the tubular body, wherein a respective cone or pyramid base associated with the respective end of the tubular body and connected to this fluid-tight, in particular sealed or glued.
  • the tubular body and / or the bottom and / or the lid of the container according to the invention are produced from one, in particular similar or the same, at least one side sealable laminate.
  • this laminate may also have a double-sided sealability in order to produce an overlapping seal in edge regions of blanks made from this laminate, so that the respective edge regions can be connected to one another in the form of lapelsis, ie overlapping by sealing are.
  • the laminate can also be designed to be sealable over its entire surface at its respective outermost layer.
  • the laminate has a barrier layer composed of one or more of the following materials: polyethylene terephthalate-silicon oxide (PET-SiO x ), oriented polyamide (OPA-SiO x ), ethylene-vinyl alcohol (EVOH), polyamide ( PA), aluminum, in particular aluminum foil or combinations of the materials mentioned.
