Patent ID: 8383219

Claim:
A multilayer thermoplastic container for storing and transporting a liquid bulk material, comprising: at least two insulating high-density polyethylene (HDPE) plastic layers forming an inner layer made of HDPE virgin material and an outer electrically non-conductive or insulating HDPE layer, each of the at least two layers having a thickness of less than 2.5 mm, and an intermediate layer made of HDPE plastic material comprising an additive which renders the intermediate layer electrically conductive, said intermediate layer disposed at least in a wall of the container intermediate between the inner layer and the outer layer, wherein the inner layer is interrupted by a first narrow, vertically extending plastic strip made of an electrically conductive plastic material which has a radial thickness substantially identical to a radial thickness of the inner layer, and wherein the outer layer is interrupted by a second narrow, vertically extending plastic strip made of an electrically conductive plastic material which has a radial thickness substantially identical to a radial thickness of the outer layer, with both the first and second narrow, vertically extending plastic strip being electrically connected with the intermediate layer.
