<p>A container (10) having a multi-faceted waist (22, 122, 222, 322, 422) construction. The waist (22, 122, 222, 322, 422) is formed by a plurality of chordal stiffening ribs (26, 126, 226, 326, 426) which define a regular transverse polygon (28, 128, 228, 328, 428). The shape of the waist (22, 122, 222, 322, 422) functions to resist ovalization of the container (10) at its waist (22, 122, 222, 322, 422) and dome (18) and to enhance the container (10) top loading capability. For maximum ovalization resistance, an odd number of chordal stiffening ribs (26, 126, 226, 326, 426) is utilized.</p> |
