The technology behind AquaCrave

Our patented FlexBeam technology ( Patent No.: US 8,550,280 B2 ) -  a flexible beam that seals both the button and the spout, forming a leak-proof water bottle.  ONLY when you press the button does the spout open for drinking.  NO more hidden complex mechanisms or metal springs that cannot be clean.  

Most water bottles have only one opening with no vent but AquaCrave is back vented as the button is pressed, which allows for flow control.  The deeper you press the button, the faster you can drink.  As soon as the button released, the FlexBeam will automatically push back against the spout to create a leak-proof water bottle.
