Abstract: The invention relates to a container (1) of thermoplastic material with at least one support (4), which is arranged in the interior of the container, extends between opposing container walls (2) and is anchored at each end to the container walls with a positive engagement and/or a material bond, the support (4) comprising at least one supporting strut (5) and the supporting strut (5) substantially absorbing a supporting load on the container walls (2) induced by negative pressure in the container, and a tensile force that is induced by positive pressure being absorbed by at least one tension-resistant bracing element in the form of a tension-resistant band (8) which extends between the container walls (2).

Abstract: The invention relates to a filler neck (1) for an auxiliary liquid reservoir for a motor vehicle, in particular for a urea reservoir, having a neck housing (9), which defines a mouth hole stub (10) for a filler nozzle (7) and a filling channel (11) leading into the reservoir, wherein a receiving structure for a filler nozzle (7) is provided within the neck housing (9). At least one venting path, which is of enlarged cross section, at least in a section or sections, and of chamber-like or labyrinth-like design, is formed within the neck housing (9), allowing a venting flow parallel and counter to the refilling volume to flow through the neck housing (9) during refilling.

Abstract: The invention relates to a thermoplastic tank (1) with at least one insert part which is provided in the interior of the tank (1) and is inserted into the tank (1) through an opening (3) in a tank wall (2) and is sealed against a peripheral flange (4) provided in the region of the opening (3). The flange (4) is formed integrally with the tank wall (2) and is countersunk therein.
