ABSTRACT:
Hollow plastic blow-molded containers have a tubular bodies and integral improved, self-supporting bases. The bases have distinctly shaped supporting feet disposed on legs at or near the periphery of the container bottom. The container legs extend outwardly and downwardly from the central region of the container on the inner side of the container bottom and extend downwardly from the container sidewalls on the outer side and are separated by ribs which coverage in a central region at the base of the container. At the terminal end of each of the container legs, there are horizontal contact surfaces or feet which are defined by foot edges which include an inner foot edge portion and an outer foot edge portion, the outer foot edge portion includes a pair of outer far corner foot edges and a far middle foot edge portion. The far middle foot edge portion extends radially to a point further than the outer far corner foot edges. The differences between the middle and far outer corner foot edge radii give rise to a container footprint which is essentially non-uniform with the circumference of the container. The unique, non-uniform footprint provides manufacturing advantages in terms of an expanded processing window which is well-suited to a high speed manufacturing environment.
