AI Technical Summary

Problems solved by technology

However, by mixing conductive fillers and using co-extrusion blow molding, what is not guaranteed is the release of impurities from the container wall to the filling material
In addition, it is complicated to manufacture multilayer walls for inner containers by blow molding

Embodiment Construction

[0015] exist figure 1 , the main parts of the transport and storage container are shown in exploded view. A cuboidal stable outer container 10 with a stabilizing frame structure 12 at the bottom is adapted to receive a cuboidal inner container 14 . The inner container 14 is produced by blow molding and serves to receive a filling material, usually a high-purity liquid, preferably a flammable liquid. The closed top inner container 14 is made of stabilizer free polyethylene, preferably high purity HDPE, and has a single wall construction. The purity of this plastic material is such that the inner container releases less than 100ppt (parts per trillion, corresponding to 10 -12 ) impurities. The vertical side surfaces of the inner container, ie its peripheral surface, are closely surrounded by a conductive plastic foil 16, which is applied, for example by gluing. The ends of the plastic foils 16 firmly applied to the vertical side surfaces of the cuboid-shaped inner container ...

Abstract

The invention relates to a transport and storage container of plastic for a filling material, having an inner container (14) of polyethylene which is produced in the blow-molding method and which hasa single-layer wall structure. The inner container (14) is accommodated by an outer container, which is open at the top and which contains at least one layer of electrically conductive plastic. The outer lateral surface of the inner container (14) is wrapped with an electrically dissipative flexible material (16), wherein at least one electrically conductive tab (18) covers at least part of the top side of the inner container (14).

Description

technical field [0001] The present invention relates to a plastic transport and storage container for filling material comprising an inner container for receiving filling material having a capacity of 50 L to 5000 L and an outer container open at the top which houses the inner container and comprises at least one A layer made of conductive plastic material. Background technique [0002] DE 201 07 962 U1 discloses a container of this type. In order to prevent static charges that could lead to gas discharges, conductive fillers are mixed into the plastic material of the inner container in order to achieve a certain conductivity and thus an electrical antistatic or charge dissipation effect. The outer container is likewise made of plastic material and has a multilayer structure, the inner and outer layers of which are formed from electrically conductive plastic material. [0003] In the case of high-purity filling materials, such as in the chemical industry, the plastic mater...
