摘要:
The present invention relates to an operating fluid container (1) composed of thermoplastic for a motor vehicle, comprising a reinforcing element (10; 11, 12), which is arranged between two container walls (2, 3) of the operating fluid container (1) and is at least indirectly joined to the container walls (2, 3). The operating fluid container (1) according to the invention is characterized by the fact that the container walls (2, 3) are joined to one another indirectly via the reinforcing element (10; 11, 12) by means of at least one joining element (20; 21 - 25). In this arrangement, the joining element (20; 21 - 25) comprises at least two material layers (21 - 25) joined to one another, wherein a joining force joining the two material layers (21, 22) to one another is less than a joining force between the joining elements (20; 21 - 25) and the container wall (2, 3) and/or between the joining element (20; 21 - 25) and the reinforcing element (10; 11, 12).
