Drink bottles with bite-actuated mouthpieces

DRINK BOTTLES WITH BITE-ACTUATED MOUTHPIECES Abstract Drink bottles (10), or containers, with bite-actuated mouthpieces (72). In some embodiments, the mouthpieces (72) are self-sealing mouthpieces that are biased to return from a dispensing configuration to a closed configuration. The bottles (10) may be rigid or collapsible and may include a removable cap assembly (14). In some embodiments, the bottles (10) include a manual on/off valve (72) adapted to prevent drink fluid from being dispensed regardless of the mouthpiece's (72) configuration. In some embodiments, the bottles (10) include a straw extending into the bottle (10) and/or a drink tube (74) extending from external of the bottle (10) and/or an air return system. In some embodiments, the bottles (10) include a dispensing spout (100) that is pivotally coupled to the cap (14) of the drink bottle (10). In some embodiments, the dispensing spout (100) includes a mount for the mouthpiece (72) and/or cooperates with the cap (14) to provide a manual on/off valve to selectively restrict flow of drink fluid from the bottle (10) regardless of the mouthpiece's (72) configuration.
