Product and package with a photosensitive use-evident feature
A product includes a container, a photosensitive material carried by the container and responsive to ultraviolet light, and a UV protector carried by the container to protect the photosensitive material from exposure to UV light. A method of producing a food or beverage container includes applying a photochromic material to a food or beverage container that is responsive to ultraviolet (UV) light so as to darken upon exposure thereto, and protecting at least a portion of the photochromic material from exposure to UV light.
1. A product that includes:
a food or beverage container;
a photochromic material carried by the container and responsive to ultraviolet (UV) light so as to darken upon exposure thereto; and
a UV protector carried by the container to protect the photochromic material from exposure to UV light, and including an appliqué with a first portion and a second portion movable with respect to the first portion to expose a previously unexposed portion of the container to UV light.
2. The product set forth in claim 1 that further includes a closure coupled to the container, and the appliqué coupled to the closure and movable upon closure removal to expose a previously unexposed portion of the container to UV light.
3. The product set forth in claim 1 wherein a container label includes said appliqué.
4. The product set forth in claim 1 wherein the UV protector is carried by an outside surface of the container.
5. The product of claim 1 including a UV light source carried by the container.
6. The product set forth in claim 1 including a separate element carried on a wall of the container and including the photochromic material.
7. The product set forth in claim 1 wherein at least a portion of the container itself is composed of the photochromic material.
8. The product set forth in claim 1 wherein the container carries an internal coating of the photochromic material.
9. The product set forth in claim 1 wherein the photochromic material includes a contrast portion that is at least one of pre-exposed to UV light or selectively covered with the UV protector.
10. A package that includes:
the product set forth in claim 1 ;
an original flowable product dispensably disposed within the container;
a closure coupled to the container; and
a UV light source coupled to a base of the container, and an opening indicator electrically coupled to the UV light source and the closure to activate the UV light source upon opening of the package.
11. A package that includes:
the product set forth in claim 1 ;
an original flowable product dispensably disposed within the container;
a closure coupled to the container; and
a UV light source coupled to a neck of the container and an opening indicator electrically coupled to the UV light source and the closure to activate the UV light source upon opening of the package.
12. A package that includes:
the product set forth in claim 1 ;
an original flowable product dispensably disposed within the container;
a closure coupled to the container; and
a UV light source carried in a punt of the container and wherein the photochromic material is carried by a body of the container, and includes a contrast portion that is at least one of pre-exposed to UV light or covered with the UV protector, and an unexposed or uncovered portion adjacent to the contrast portion.
13. A package that includes:
the product set forth in claim 1 ;
an original flowable product dispensably disposed within the container; and
a closure coupled to the container;
