US Patent 10358270 Closure assemblies and drink containers including the same

Closure assemblies and drink containers including the same. A drink container includes a liquid vessel and a closure assembly. A closure assembly includes a closure base, a valve insert, and a valve insert retainer. The closure base defines a base interior side, a base exterior side, and a closure base passage. The valve insert is operatively received within the closure base passage and includes a liquid inlet and a liquid outlet. The valve insert is configured to transition the closure assembly between a closed configuration and a drink configuration. The valve insert retainer is configured to prevent removal of the valve insert from the closure base when operatively coupled to the valve insert. The valve insert is configured to be selectively and repeatedly received by and removed from the closure base passage only when the valve insert retainer is selectively removed from the valve insert.
