1. A drink container, comprising:
- a liquid container having a neck with an opening and having an internal compartment sized to hold a volume of drink liquid;
a cap assembly removably coupled to the neck of the liquid container and adapted to restrict dispensing of drink liquid from the internal compartment of the liquid container through the opening, wherein the cap assembly includes a body, wherein the body includes a lower portion that defines a lower edge that is adjacent to the liquid container, and wherein the lower portion defines a recess facing the internal compartment of the liquid container when the cap assembly is coupled to the neck of the liquid container; and
a purification assembly coupled to the body of the cap assembly, wherein the purification assembly includes an ultraviolet (UV) bulb positioned within the recess, wherein the UV bulb is adapted to selectively emit UV light in the germicidal spectrum for a predetermined period of time and to thereby purify a volume of drink liquid held in the internal compartment of the liquid container.

Abstract
Water purifying drink containers include a liquid container, a cap assembly removably coupled to the liquid container, and a purification assembly that emits ultraviolet (UV) light in the germicidal spectrum to purify a volume of drink liquid held in the liquid container. In some embodiments, the purification assembly includes a UV bulb positioned within a recess of the cap assembly facing the internal compartment of the liquid container. In some embodiments, the UV bulb further emits light in the visible spectrum and the drink container includes an indicator that becomes illuminated with visible light to indicate to a user when the UV bulb is emitting UV light.

21. A drink container, comprising:
-
a liquid container having a neck with an opening and having an internal compartment sized to hold a volume of drink liquid; a cap assembly removably coupled to the neck of the liquid container and adapted to restrict dispensing of drink liquid from the internal compartment of the liquid container through the opening, wherein the cap assembly includes a body, wherein the body includes a lower portion that defines a lower edge that is adjacent to the liquid container; a purification assembly coupled to one of the liquid container and the body of the cap assembly, wherein the purification assembly includes an ultraviolet (UV) light emitter adapted to selectively emit UV light in the germicidal spectrum and light in the visible spectrum for a predetermined period of time and to thereby purify a volume of drink liquid held in the internal compartment of the liquid container; and an indicator adapted to indicate to a user when the UV light emitter is emitting UV light, wherein the indicator includes a visible-light-transmissive portion that is configured to become illuminated when the UV light emitter is emitting light in the visible spectrum. - View Dependent Claims (22, 23)
