Patent attributes
Drink containers with mouthpiece assemblies having a dispensing configuration and a stowed configuration. A mouthpiece assembly defines a liquid passage through which drink liquid may be dispensed when the mouthpiece assembly is in the dispensing configuration and includes means for selectively restricting the flow of drink liquid through the liquid passage when the mouthpiece assembly is in the stowed configuration. In some examples, the means for selectively restricting the flow of drink liquid include a tube that at least partially defines the liquid passage and which includes a crimping region. The crimping region may be constructed of a resiliently and reversibly deformable material that is adapted to restrict the flow of drink liquid through the liquid passage when the mouthpiece assembly is in the stowed configuration. In some embodiments, the mouthpiece assembly includes a means for automatically releasing the mouthpiece assembly from its stowed configuration to a dispensing configuration.
