Abstract

1. A method of manufacturing a storage tank (B), made of thermoplastic material, for liquids, in particular fuel oil, wherein at least two constituent tanks (E1 , E2 ) are moulded simultaneously in a blow mould (F1 , F2 ) or a rotational mould and can be connected to one another at least by a lower and an upper connecting passage (1, 2), wherein the constituent tanks (E1 , E2 ) and the connecting passages (1, 2) may at the same time be moulded as one piece, characterised in that the substantially cuboid constituent tanks (E1 , E2 ) are moulded in a position relative to one another in which the constituent tanks (E1 , E2 ) are only close together at one edge or in the vicinity of one edge and the connecting passages (1, 2) are formed on these edges, and, following removal of the part from the hollow mould (F1 , F2 ), in order to bring the constituent tanks (E1 , E2 ) into the final form, they are pivoted together about said tank edges or about a bending axis in the vicinity thereof, wherein the connecting passages (1, 2) are deformed and the constituent tanks (E1 , E2 ) approach one another, preferably into a relative position in which the side walls (3, 4) of the cube are parallel to one another.
