Abstract

Drink bottles, or drink containers with cap assemblies that include a drink spout. In some embodiments, the drink spout is pivotally coupled to a base of the cap assembly. In some embodiments, the drink spouts include mouthpieces, including self-sealing mouthpieces. In some embodiments, the cap assembly includes a handle, which may include at least one guard for the drink spout and/or mouthpiece. In some embodiments, the drink containers include a manual on/off valve. In some embodiments, the dispensing spout includes a mount for the mouthpiece and/or cooperates with the cap to provide a manual on/off valve to selectively restrict flow of drink fluid from the drink container regardless of the drink spout'"'"'s and/or mouthpiece'"'"'s configuration. In some embodiments, the drink containers include a drink tube extending from external of the drink containers and/or an air return system.
