A universal case for PET bottles of both a base-cup type and a petaloid type includes an outer shell (4, 6) and a plurality of support ribs (30, 32, 34, 36, 80) for reinforcing the shell. The outer shell and the support ribs form a plurality of bottle pockets (25) for receiving the bases of PET bottles. A bottle seating structure (40) in each bottle pocket (25) includes a plurality of dual-base-engagement projections (52), a base-cup-bottle alignment structure (42) and a petaloid-bottle alignment structure (48, 50). The number of dual-base-engagement projections (52) equals the number of petaloid lobes (124) formed in the base of a PET bottle of the petaloid type. The dual-base-engagement projections (52) engage an annular indentation (108) in the base cup (102) of PET bottle (100) of the base-cup type. The dual-base-engagement projections (52) also engage petaloid-lobe-separation notches (127) between the petaloid lobes (124) of a PET bottle of the petaloid type. The base-cup-bottle alignment structure (42) defines a base-cup-bottle annular-bottom-surface contact plane and the petaloid-bottle alignment structure (48, 50) defines a petaloid-bottle lobe-bottom-surface contact plane. |
