The design and development of the straw began in 2004. Numerous designs were prototyped and tested for safety and performance resulting in the current design.
Elastomeric materials for the valve were evaluated for both performance and safety. Critical material properties were thoroughly evaluated to include; Mechanical, Thermal, Chemical, Compression-set and FDA approval.
The straw design/development evolved to challenging criteria for safety, performance, aesthetics and low manufactured cost in a high volume automated production environment with 100% Quality Control.
