The tether is transitionable between a closed arrangement that positions the closure over the drink spout and an opened arrangement in which the closure is spaced away from the drink spout. The biasing device biases the tether from the closed arrangement toward the opened arrangement. The cap assemblies can incorporate features to enhance handling and use, including as a drink spout format, connection of the closure over the drink spout, connection of the closure to the base via the tether, and/or other a swinging a handle.
