After manufacturing, by known means, a tubular body (30), the successive drawing of two pieces is carried out in order to form two cups (50, 70). Two cups (50, 70) are simultaneously inserted into the body (30) with the drawing tool and their lateral parts (51, 71) are joined to the inner face of the body (30). The prescoring (32) and grooving (33) of the lid are then carried out. Next the end of the body (30) is folded over in order to form a seam (35), thus completing the lid. After filling the body, a bottom comprising two cups (50', 70') and a seam (35') are installed, as previously. The body (30) and the external cups (50, 50) are made of the same rigid material. This type of package is intended equally well for packaging chemicals, foodstuffs and other industrial products.
