Patent ID: 8191727

Claim:
A drink container, comprising: a liquid container having a neck with an opening and having an internal compartment sized to hold a volume of potable drink liquid; a cap assembly removably coupled to the liquid container, the cap assembly comprising: a base removably coupled to the neck of the liquid container and including a through-passage; a first catch structure; a mouthpiece assembly extending through the through-passage of the base and defining a liquid passage through which drink liquid from the liquid container may selectively flow, and further defining an inlet through which drink fluid in the internal compartment may enter the liquid passage and an outlet through which drink liquid from the internal compartment of the liquid container is selectively dispensed, wherein the mouthpiece assembly is configured to be selectively configured between a dispensing configuration, in which the liquid passage permits drink liquid to flow from the internal compartment at least into the liquid passage, and a stowed configuration, in which the liquid passage restricts the flow of drink liquid through the liquid passage, wherein the mouthpiece assembly is biased to the dispensing configuration, wherein the mouthpiece assembly is configured to be selectively coupled to and decoupled from an operative position on the base of the cap assembly via an underside of the base but not via a top side of the base, and wherein the mouthpiece assembly comprises: a mouthpiece portion that includes the outlet; a tube that defines at least a portion of the liquid passage for drink liquid to flow from the internal compartment to the mouthpiece portion, wherein the tube includes a crimping region constructed of a resiliently deformable material and is adapted to restrict the flow of drink liquid through the liquid passage when the mouthpiece assembly is in the stowed configuration, and wherein the mouthpiece portion and the tube are constructed as a unitary assembly of the resiliently deformable material; an anchor portion extending from the tube, wherein the anchor portion is sized to restrict passage of the anchor portion through the through-passage of the base of the cap assembly; and a second catch structure adapted to be selectively engaged with the first catch structure to retain the mouthpiece assembly in the stowed configuration; and a user release mechanism adapted to automatically disengage the first and second catch structures upon actuation of the user release mechanism and thereby release the mouthpiece assembly to move via its bias from the stowed configuration to the dispensing configuration.
