  • a housing provided with a housing underside with a housing set-down surface, a housing upper side, housing side walls and a housing interior,an electrical anode contact andan electrical cathode contact,wherein the housing underside has configured upon it, on mutually opposite edges, set-back guides which extend in the direction of the housing upper side from a set-down plane defined by the housing set-down surface,wherein the anode contact and the cathode contact in one or more of the set-back guides are arranged on the housing at a distance of at least five millimeters from the set-down plane, whereby that region of the respective housing side wall which is adjacent to the anode contact and the cathode contact terminates at a distance of at least five millimeters from the set-down plane, wherein the housing underside, considered from the housing set-down surface, is provided with a stepped surface profile section, at least at the periphery of the housing, whereby said stepped surface profile section which, accordingly, is removed from the set-down plane, is not limited laterally by housing side wall segments such that, even when the container is set down on sludge, adhesion of dirt which penetrates to those regions of the housing underside which are recessed in this stepped arrangement is inhibited.
