Abstract: The packaging container consists of a mechanically stabilizing case of paper, cardboard and/or metal with inserted sealing liner, which sealing liner is in the form of a plastic bubble with a neck part shaped from it and extending above the case. Both elements are manufactured separately and coupled together with the aid of an adapter cover. This is lockingly connected with the neck of the sealing liner and adapted to an opening in the case, into which it can lock. It is slipped over the sealing liner preform before the stretching and inflating of the liner and is secured against shifting by means of fixing cams.
