| 摘要 |
The present invention features an ultraviolet indicating closure comprising (a) a primary support body; (b) means for fitting the primary support body and the closure onto a container, wherein the container comprises a specific, pre-identified ultraviolet radiation protecting product; (c) at least one ambient surface located on the primary support body, wherein the ambient surface is exposed, at least in part, to ambient conditions and ultraviolet radiation; and (d) an ultraviolet radiation indicator integrally formed within at least a portion of the ambient surface and comprising a first, base color, the ultraviolet radiation indicator comprising a photo-chromic makeup that induces a single color change within the ultraviolet radiation indicator to a second, indicating color based upon breach of a pre-determined, incorporated ultraviolet radiation intensity threshold by the ultraviolet radiation incident upon the ambient surface, the single color change and the second, indicating color corresponding to and signaling the appropriateness for use of the specific, pre-identified ultraviolet radiation protecting product formulated within the container.
