Реферат: An internally hollow body (1) made of plastic has a cavity (2) for containing liquid, solid or gaseous material, and comprises a main body (4) shaped and having an inner surface (8) that defines at least partially the cavity (2). The inner surface (8) terminates in a shaped edge (10) that delimits a coupling aperture (12) to the cavity (2). The internally hollow body (1) further comprises a closure body (14), having an outer sealing surface (18) suitable to engage at least partially with the inner surface (8) of the main body (4). This closure body (14) is suitable to close at least partially the cavity (2) in correspondence of the coupling aperture (12). The main body (4) is joined to the closure body (14) at least partially along the shaped edge (10) by means of a joining element (20), over-moulded to the main body (4) and the closure body (14) and covering said over-moulding seat resulting between the main body (4) and the closure body (14). A method for making the internally hollow body (1) provides for over-moulding the joining element (20) by injection moulding for example with the use of an over-moulding mould (500).
