A method for producing a thermoplastic container (1) for gases or liquids. First, in an injection mould having a first (28) and a second mould (29), in a first position providing each a cavity (34) for an upper (2) and a lower shell (3), producing the shells in parallel. Next, opening the mould, the shells (2, 3) remaining in a respective mould. Then, turning or shifting at least one of the two moulds such that the concave interior sides of the shells are aligned against each other and closing the mould, so that the edge regions (7, 8) of the shells come into face-to-face contact. Injection material is injected into a cavity (49) between or adjacent to the edge areas (7, 8), forming an all-round welded seam (11) between the upper part (2) and the lower part (3). Finally the mould is opened and the at least one container is removed.
