The cup is simply opened with a small rotation, giving the user feedback on when its fully opened. In this state TOPL is always ready to snap shut as soon as it detects an inertial impulse at the right number of newtons, the patented Bi-Stable valve shuts in fractions of a second, potentially saving your loved ones from burns or your macbook! When your ready to make a move, simply rotate back and you can stow TOPL in a bag or jump on the tube, switch back to drink whenever you need.
We developed TOPL cup with a range of sizes and colours to suit the discerning cafe’ goer. We developed 12 and 8 Oz twin walled vacuum cup that keeps your drink hot for hours, which helps save energy. TOPL just launched this year, get yours while there hot!
