摘要 |
An ergonomically friendly container (10, 30) having hot-fill capabilities is disclosed. The container (10, 30) has a pre-ovalized dome (14, 34) with grip surfaces (20, 21, 40, 42) that undergo controlled deformation for accommodating a portion of the volumetric shrinkage due to hot filling, capping and cooling. Preferably, anti-racking ribs (32<u>a</u>, 32<u>b</u>) extend laterally between the grip surfaces (20, 21, 40, 42) to prevent unwanted racking or twisting of the dome (14, 34) during vacuum absorption.
