OXO Liquiseal Redesign2 - The main problem with the mug was the seal mechanism. Here, I ideated to find a method of sealing the mug withot creating a large chamber in which excess liquid and bacteria build up (as is the case with the current design.)
I settled on a telescoping silicone design with a spring click mechanism. The benifits of this design include less trapped liquid, a sealed mechanism, easier cleaning, and less wasted space.
