Activate™ enhanced water from Rising Beverage Co., Los Angeles, CA, stores vitamin, herb ingredients inside cap to protect freshness, potency. Company opts for slim 16.9-ounce polyethylene terephthalate (PET) bottle after tests show biodegradable, corn-based polylactide bottle protects shelf life for only two weeks. Patented cap consists of knurled blue chamber atop natural tamper-evident closure. When knurled top is twisted clockwise, small plastic blade cuts seal in chamber, small armature opens releasing ingredients into water below. “The cap provides a new form of ingredient delivery and an easy way to keep healthy,” says cofounder Anders Eisner. Designed as replacement for hard-to-swallow vitamin pills, messy powdered supplements, each of four sugar-free flavors of low-calorie, preservative-free beverage delivers functional benefit: Vitamin/Fruit Punch, Immunity/Orange, Antioxidant/Berry, Energy/Lemon Lime. Launched in Los Angeles, CA, in February 2008, distribution now encompasses much of southern California. Product also sells online in four-count carrier (one bottle of each flavor), 24-count single-flavor shippers.
