The RightWeight bottle weighs only 7.95 g and offers top-load performance of 33 kg without nitrogen dosing, using standard 26/22 caps. The increased resistance of the bottle helps eliminate over-squeezing issues often experienced by end consumers with ultra-light bottles, resulting in spilled contents. Increased resistance also allows consumers to unscrew caps and open the bottle more easily. Additionally, the bottle can be adapted easily to existing production lines with standard cap formats, and design elements can be adapted for existing or new commercial bottle designs as needed.
