Abstract
A container comprises a substantially rigid outer container and a readily deformable inner bag, wherein the outer container and the inner bag consist of different thermoplastic plastic materials such that the outer container and the inner bag do not undergo a weld connection with one another, with a container opening and at least one pressure balancing opening in the wall of the outer container for balancing the pressure in the gap between the outer container and the inner bag when the inner bag contracts, wherein integrated into the layer of the inner bag, which is directed towards the outer container, and/or into the layer of the outer container, which is directed towards the inner bag, are microbodies, of a material which does not melt during the manufacture of the container, which produce irregularities on the surface of the layer(s) in which microbodies are imbedded.
