Cap assemblies with magnetic closure retention mechanisms and drink containers including the same

A cap assembly for a container, comprising:

• a base configured to be removably coupled to the container, the base comprising a handle immovably fixed to the base;
• a drink spout extending away from the base;
• a closure configured to selectively transition between a closed configuration, in which the closure is engaged with the drink spout and obstructs a passage through the drink spout, and an open configuration, in which the closure is not engaged with the drink spout and does not obstruct the passage through the drink spout;
• a tether coupling the closure to the base, wherein the tether is configured to constrain movement of the closure such that the closure travels along a predefined path;
• and
• a magnetic closure retention mechanism configured to retain the closure in an open configuration.

A cap assembly for a drink container having a neck with an opening and having an internal compartment configured to hold a volume of potable drink liquid, the cap assembly comprising:

• a base configured to be removably coupled to the container, the base comprising a handle immovably fixed to the base;
• a drink spout extending away from the base;
• a closure configured to selectively transition between a closed configuration, in which the closure is engaged with the drink spout and obstructs a passage through the drink spout, and an open configuration, in which the closure is not engaged with the drink spout and does not obstruct the passage through the drink spout;
• a tether coupling the closure to the base, a first portion of the tether extending around the drink spout and a second portion of the tether extending around the closure;
• and
• a magnetic closure retention mechanism configured to retain the closure at least partially against the handle.
