When you’re ready to take a drink, simply half-twist the lid until it clicks, then sip from any angle. And for a leakproof seal while traveling, continue to twist the inner cap clockwise, past the drinking position, until it stops. When you get back home, disassemble the cap by twisting the inner lid counterclockwise until it comes out completely, and throw each part in the dishwasher for an easy clean.
