Abstract
A container for a hydraulic medium made of a plastic material has a container cup (,), which can be closed by a cover (,). The positions of the container cup (,) and the cover (,) in respect to each other are matched along a joint (,), and are fixed in place by a fitting insert (,). Faces (,), which adjoin each other, are respectively arranged on the container cup (,) and the cover (,). A welding plate (,), which is also made of a plastic material, extends over the adjoining surfaces of the container cup (,) and the cover (,), and is matched to the adjoining faces (,). The container cup (,) and the cover (,) are sealingly connected with each other via the welding plate (,) by an inertia welding process so as to prevent particles of the plastic material, which are generated in the form of lateral welding waste in the course of the inertia welding process, to reach the interior of the container for the hydraulic medium.
