The body (2) of the tank (1) is manufactured in a mould (M) with a plastic material by means of rotational moulding. Before manufacturing the body (2), a stabilizing structure (9) is pre-positioned in the mould (M), said structure including a rigid longitudinal rod (10) which extends between two opposite wall portions of the mould (M), and at least one transverse bulkhead (11) which extends from the rod (10). Such a structure is substantially heat-stable at the melting temperature of the plastic material with which the body (2) is formed. After moulding, the body (2) encircles and grips at least part of the at least one bulkhead (1 1), such that the stabilizing structure (9) is anchored in the body (2). |
