The thickness of the inner wall is less than that of the wall of the mould, at least one recess is provided inside the upper part of the mould wall and the inner wall of the hot-top is placed in the recess, with its surface essentially flush and aligned with the inner surface of the mould, so as to form a closure wall separating the interior of the recess from the interior of the mould.
