The bottom wall (21) comprises a peripheral annular portion (23)), a median portion (24) and a rib portion (25) with the approximate form of an inverted U and joining the peripheral annular portion (23) and themedian portion (24). The median portion (24) comprises an annular panel (24a) and a central panel (24b) joined to each other by an axial step portion (24c), an outer peripheral edge of the annular panel (24a) being incorporated to the annular rib portion (25), said axial step portion (24c) being constituted by a material that is plastically deformed from the adjacent annular panel portion (24a) and from the central panel portion (24b).
