A petaloid base (14) for a self-standing container (10) is described. The base (14) has a central longitudinal axis (12), a spheroidal underlying base contour, and a plurality of spheroidal foot formations (16) that interrupt and project from the underlying base contour to define a corresponding plurality of feet (16). Each foot formation (16) has an elliptical intersection with the underlying base contour, the elliptical intersection defining a transition between the underlying base contour and a foot formation (16). A ratio of D2:D1 is in the range of 1:1 to 1:1.38, wherein D1 is a radial distance from the central longitudinal axis (12) to a junction between the base (14) and a side wall (48) of the self-standing container (10), and D2 is a radial distance from the central longitudinal axis (12) to a radially outermost extremity of the transition. |
