HOW DOES DUO WORK?
- This product line comes in two versions:
- One containing internal ‘one-way’ valves - called ‘Duo’
- The other providing basic hygiene, without internal ‘one-way’ valves - called ‘Duo lite’
- Both ‘Duo’ and ‘Duo Lite’ include two visually distinguishable personal drinking tubes
- Each of the personal drinking tubes can be independently opened for drinking while the other tube stays closed
- Duo’ contains small silicone one-way valves that allow beverage to flow through each drinking tubes in only the outward direction, thereby preventing saliva, or beverage that has entered a drinker’s mouth, from returning to the bottle
- ‘Duo’ also contains an air intake hole to equalize the air pressure inside the container as the beverage is consumed. This hole also contains a silicone one-way valve to prevent beverage leakage from the air intake hole
- ‘Duo’ is compatible with existing capping equipment, and costs only a fraction more than a regular sports cap
