<p>Each thermoplastic container of a battery of containers includes reinforcing parts embedded in its walls espec. in attachment positions. The reinforcing parts are from a material hot weldable with thermoplastic material pref. metal, and are covered with a layer of thermoplastic material which is welded to the container wall. The parts (33, 34) of the thermoplastic layers (24) on both sides (26, 27) of the reinforcing part (22) are so held together or held apart along their outer edge (31) that they permit a relative movement between the reinforcing part (22) and the thermoplastic layers (24) in a plane parallel to the reinforcing part (22).</p> |
