NOVELTY - A water storage and disinfection container comprises a container, that is transparent to ultra violet light, a cap comprising internal threaded screw-on tightening and sealing feature, cap security seal that is manually fixed around the base of cap and the neck, and comprising material that cures in response to ultraviolet light fluence, where the cap security seal is flexible in an uncured state and rigid in cured state; and an ultraviolet light transparent insert comprising serialized identification characters embossed in relief upon concave or hollowed inward shape surface of insert.    USE - As a solar water storage and disinfection container (claimed).    ADVANTAGE - The solar disinfection (SODIS)-type water disinfection is uniquely and inherently fail-safe, thus confirming to the user that the bottle contents are secure, safe, and healthful for human consumption; is socio-economic in nature, as it enables the establishment of a wide network of very local, grass-roots-based entrepreneurial endeavors, all based upon the need to create, distribute, sell, and recycle/support the ensuing products. It provides a verifiable, fail-safe, permanent, and tamper-proof indication of solar-based water ultraviolet purification/disinfection integrity; The present container overcomes the risks and uncertainties caused by the lack of positive visual confirmation of water disinfection integrity, while simultaneously passively provides both the metrology for measuring adequate ultraviolet disinfection, and the secure and tamper-proof indication. Unlike SODIS systems that utilize unstable and cancer-causing plastic compounds for the bottle and other components, the container incorporates no such materials, thus posing no additional long-term health risks; provides a safe and reliable, secure, and cost-effective solar-based water disinfection container design, thus creating a compelling resource for enabling widespread implementation of this unique SODIS technology.    DETAILED DESCRIPTION - A water storage and disinfection container comprises a container transparent to ultra violet light, and having a top and a bottom portion, where the top of the container is narrower than the bottom, and the narrow portion forms a neck, and the bottom comprises a concave or hollowed inward shape corresponding to the top; a cap comprising internal threaded screw-on tightening and sealing feature, where the cap is attachable to neck; cap security seal that is manually fixed around the base of cap and the neck, and comprising material that cures in response to ultraviolet light fluence, where the cap security seal is flexible in an uncured state and rigid in a cured state; and an ultraviolet light transparent insert comprising serialized identification characters embossed in relief upon a concave or hollowed inward shape surface of the insert, where the concave surface or hollowed inward shape of the insert corresponds to the top and the cap, when cap is attached to the neck of container, where insert is fixed to the concave bottom of the container. An INDEPENDENT CLAIM is included for water storage and disinfection container system comprising containers, each the container being transparent to ultraviolet light, cap comprising an internal threaded screw-on tightening and sealing feature, cap security seal, an ultraviolet light transparent insert, an end cap, where the end cap is placed upon the top of a first container of the containers, where the end cap is shaped to conform to the top of the first container, the end cap further comprising an insert, where the insert being fixed into a bottom cavity of the end cap and comprising embossed identification characters; a proxy end cap, where the proxy end cap is placed into the bottom of a last container the proxy end cap shaped similarly to the end cap and comprising a proxy cap security seal similar to the security seal, where the proxy security seal is manually placed around the proxy end cap; and each the container nested with another, top into bottom cavity.
