Kühlmittelbehälter und Verfahren zu dessen Herstellung

摘要

The present invention provides a low cost coolant container that is easy to produce without decreasing its ability to maintain a coolant. The coolant container (1) comprises an outer container (11) and an inner container (12) wherein the cylindrical members (111) and (121) and the plate members (112) and (122) of the outer container (11) and the inner container (12) are engaged at the peripheral end such that even if an external force acts on the flat surface of the plate members (112) and (122) the stopping means (111a) and (121a) of the engaging portions A and B prevent the plate members (112) and (122) from sinking toward the hollow portion (13) side by supporting the plate members (112) and (122) and resisting the external force and as a result the container has the required structural strength and its ability to maintain a coolant is preserved.
