The inventor of this wacky travel mug acknowledges that most insulated beverage holders inevitably loose heat––a fact that inspired the creation of this rather interactive product. The portable coffee cup has been enhanced with a quirky feature that allows the drinker to sustain and even increase the temperature of her cuppa.

Wang Jin called his tea thermos the R-Cup because of the rotating movement that it's been designed to integrate. Within the lid is a spinning component that is activated with the whipping around of a red ball on a string, outside the container. The travel mug would boast a superior air-tight seal, inviting the user to engage in a circular motion with the hand that holds it. This kinetic energy would stir up a warming mechanism.

The R-Cup is the perfect low-cost, convenient and eco-friendly product that would appeal to the active, hot-drink-loving, millennial consumer base. It won a 2014 Red Dot Design Award.
