  • a liquid container having a neck with an opening and having an internal compartment sized to hold a volume of drink liquid;

    a cover assembly arranged in proximity to the neck of the liquid container, wherein the cover 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 cover assembly is in proximity to the neck of the liquid container;

    a purification assembly arranged in relation to the body of the cover 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, the UV bulb having an at least partially circular configuration; and

    wherein the cover assembly further includes a convex spherical reflector positioned to reflect light from the UV bulb toward the internal compartment of the liquid container, the UV bulb being positioned around the perimeter of the spherical reflector, a portion of the spherical reflector extending into a region within the circular configuration of the UV bulb and wherein the spherical reflector is configured to reflect light from the UV bulb toward an entirety of the internal compartment of the liquid container.
