Jossanova ValveOpen by simply pressing bottle sides
The patented membrane of food-grade silicone incorporated into the cap facilitates easy delivery of the beverage due its quick opening and closing. With the cap in the unlock (open) position, the bottle is always ready; the beverage is delivered by a light pressing of the bottle body, without which the liquid cannot flow on its own even when held up-side-down.
This responsive system allows for ease-of-use in even in the most extreme conditions while creating an insulation barrier for the liquid inside. The silicon valve permits a flow in only one direction thereby eliminating any side spurts and wasteful loss of liquid.
Press lightly on the bottle body and drink until the very last drop.
