Container for a fluid in particular motor oil pan or gear oil pan for a motor vehicle

The receptacle e.g. engine oil pan (1), has a circular opening (2) and a closure body that are complementary to each other. A sealing closure is designed as a bayonet closure. The closure body is centered in the opening by a sealing agent. A clearance of the opening is larger than diameter of the opening. The opening comprises extensively retaining surfaces and/or guide surfaces, which cooperate positively with parts of the closure body. The closure body is axially guided over an arc portion at a region of the opening.
