A recently granted patent (Publication Number: US11884447B2) discloses a unique polymeric container design featuring a finish defining the opening, a shoulder, and a base for upright support. The container includes body ribs and a shoulder rib with specific dimensions and curvature. The shoulder rib is continuously curved with a maximum height five times greater than its depth, featuring indentations spaced apart and a specific radius. The design ensures stability and aesthetic appeal, with the shoulder rib located strategically above the center of gravity and at a specific distance from the base.

Furthermore, the patent details a variation of the polymeric container with a tapered body, giving it an hourglass shape. This design includes flexible body ribs, a shoulder rib with specific height-to-depth ratio, and at least one indentation for added visual interest. The shoulder rib is defined by the container's sidewall, curving along its length with distinct radii. The upper depth of the shoulder rib at the indentation is significantly less than the lower depth, enhancing the container's overall appearance and functionality. These innovative features set this polymeric container design apart, offering a blend of structural integrity and visual appeal for various packaging needs.
