Operating fluid container with stiffening element and method for producing an operating fluid container

摘要

The present invention discloses an operating fluid container (10) made of thermoplastic material for a motor vehicle with the following features: - the operating fluid container (10) has two openings (13, 14) in opposite container walls (11, 12) of the operating fluid container (10) and a both openings (13, 14) projecting stiffening element (20); and - two stiffening element ends (23, 23 ') engage behind the container walls (11, 12) from the outside, so that the stiffening element (20) counteracts a deformation caused by internal pressure of the operating fluid container (10), the operating fluid container (10) being characterized by the following features is: - between at least one stiffening element end (23, 23 ') and a container wall (11, 12), a stabilizing element (30) is arranged; - The stabilizing element (30) has a passage opening (31) through which the stiffening element (20) protrudes; - The stabilizing element (30) comprises a first and a second thermoplastic material; and - the stabilizing element (30) is welded to a container wall (11, 12).
