Plastic liner with inner lining

Abstract

The present invention relates to a rigid plastics-material internal container () from a thermoplastic plastics material for a pallet container () or a similar large-volume retainer for storing and for transporting liquid or free-flowing filling materials, having a flexible inliner () from a thin-walled plastics-material or composite-material film that is inserted into the rigid plastics-material internal container (). For filling and removal at the base, the thin-walled inliner () at the base side has at least one filling and removal connector (), said filling and removal connector () at the front being fixedly welded into a corresponding filling and removal connector () at the base side of the rigid plastics-material internal container (). For filling from above and removal of the filling material at the base side, the rigid plastics-material internal container () and the thin-walled inliner () can in each case also be provided with an upper filling connector, wherein in this instance the upper filling connector () of the thin-walled inliner () is likewise fixedly welded into the filling connector () of the rigid plastics-material internal container (). The thin-walled inliner () that is inserted in the rigid plastics-material internal container () in the assembled final state by way of vacuuming bears in a fully planar manner on the internal surface of the rigid plastics-material internal container (), and in the empty non-filled state as well as in the filled state of the rigid plastics-material internal container () adheres in an immovable fixed manner, as if adhesively bonded, on the internal surface, in particular also on the upper base of the internal container.
