Cela / Thermos bottle

The thermos bottle Cela opens without effort, without changing position of your hand, and without getting your hands dirty, with just one hand. Once you let go the bottle, it shuts itself. So there will be no spill, if the bottle was dropped. The cross-sectional shape prevents the bottle from rolling away. The sharp edge at the spouts prevents dripping. The slight troughs in the rubberized grip area gives a haptic signal for the position of the buttons.
