The primary recessed portion surrounds a secondary recessed portion (52). When the bottom wall of the container is viewed head-on the primary recessed portion (51) has an outline which is circular, while the secondary recessed portion (52) has an outline which is non-circular. The secondary recessed portion has major and minor axes which are mutually perpendicular and intersect one another on a longitudinal axis of the container. The distance (B) across the secondary recessed portion along the major axis divided by the distance (C) across the secondary recessed portion along the minor axis is greater than 1 but not greater than 3.</p> |
