Abstract
A hot-fillable, blow-molded plastic container having a reinforced dome which controls dome distortion otherwise caused by forces associated with hot-filling and shipping. In one embodiment, the reinforced dome resists distortion, and in a second embodiment, the reinforced dome enhances ovalization distortion. The container dome is bell-shaped with an inwardly extending waist and has a plurality of vertically extending grooves passing through the waist. Each groove is inwardly concave and extends from below the waist to adjacent the finish. Arcuate lands are formed between the grooves, and optionally, can have panels with a textured pattern which add to the aesthetic appearance of the container and which provide further stiffening of the dome. When two grooves are utilized, ovalization distortion is enhanced, and when three or more grooves are utilized, distortion is prevented.
