The container (1) has at least one rib (6) extending along a wall (15) of the container in the working zone (3), the rotatable working assembly (2) is removable with respect to the container (1), and the rotatable working assembly (2) includes a pedestal (7) movable in rotation around the axis A-A′ of the working assembly (2), which comes to bear on a relief (8) formed on the bottom of the container (1).
