HOT FILL CONTAINER HAVING SUPERIOR CRUSH RESISTANCE

摘要

A hot fill plastic container (10) has a dome portion (24) with a convex outer surface that defines a maximum outer diameter (D2) of the container so as to extend outwardly beyond a main body portion (18) of the container. The dome portion has a first curved portion (26) having a first curvature and a second curved portion (32) having a second curvature. The generally egg-shaped dome portion enhances the crush resistance of the dome and provides a point of contact between containers when they are placed adjacent to one another. A circumferential stiffening groove (48) may be provided near a lower end of the dome portion.
