Customized spin-welding key to sealing KarmaCap

Closure allows users to infuse fresh vitamins into beverage and then shake the bottle to initiate health benefits of its vitamin drinks.

Branson Ultrasonics helped Karma Culture LLC overcome the challenge of welding the patented KarmaCap, a dispensing capsule that holds vitamins and other essential ingredients separate from the water until the consumer peels back the protective seal, pushes down on the cap, and gently shakes the bottle to mix the drink. The “reservoir cap” is used for Karma® Wellness Water plastic bottles.

Branson Ultrasonics Corp., a subsidiary of Emerson, helped Karma Culture LLC overcome the challenge of welding the patented KarmaCap, a dispensing capsule that holds vitamins and other essential ingredients separate from the water until the consumer peels back the protective seal, pushes down on the cap, and gently shakes the bottle to mix the drink. The “reservoir cap” is used for Karma® Wellness Water plastic bottles.

The driving force behind Karma is that vitamins deteriorate in water, causing premixed vitamin drinks to lose their strength over time. Branson’s spin-welding technology and support enabled Karma to develop a solution to seal the KarmaCap, leading to the launch of the new natural, nutrient-enhanced water line.

Achieving the hermetic (airtight) seal between the low-density polyethylene (LDPE) cap and LDPE base is critical to preserve the freshness of the vitamins and effectiveness of the drink, enhance shelf life, ensure optimal quality, and allow consumers to keep nutrients and vitamins in sight.  (A “How it Works” section of the company’s website describes the process.)
