US Patent 11834233 Cap assembly for drink containers with a sliding switch

Drink containers include a liquid container and a cap assembly removably coupled to the liquid container. Cap assemblies include a switch, a trigger and seal bar. Upon actuating the trigger the seal bar slides back to form a drink outlet opening in the cap assembly. To hold the seal bar in an open state without additional external force from the user, the switch is slid from an unlocked position to a locked positon, thereby keeping the drink outlet and a vent formed in the cap assembly open in order to cool down a warm beverage in the liquid container.
