Abstract: A package includes a container, a flowable product dispensably disposed within the container, a closure carried by the container, and an indicator within the container and adapted, upon contact with air, irreversibly to change a characteristic of the indicator that is visible from outside of the container to indicate to a user that the package has been used, wherein the closure includes a closure member carrying the indicator and having a wedge opening, and a wedge member carried in the wedge opening.

Abstract: An article, for example, a container, having an outer surface, at least a portion of which is curved, and a data matrix disposed on the curved portion of the outer surface that is optically-readable to provide information associated with the article. The data matrix comprises a plurality of optically-readable elements, one or more of which has a different dimension in a direction of curvature of the outer surface than one or more other of the elements so that the plurality of elements appear to have an expected size and shape when optically viewed in a plane perpendicular to a radial line extending from the surface.

Abstract: An authentication system including a package that includes a container and a closure, an ultraviolet (UV) protector carried by the container, and a UV light responder carried by the container so that at least a portion thereof is protected by the protector from premature exposure to UV light. After removal of the UV light protector, the UV light responder is responsive to a predetermined schedule of UV light exposure so as to change in visual appearance within a predetermined time. The predetermined schedule may include a predetermined wavelength of UV light applied in a predetermined amount and over a predetermined application time. A related apparatus and authentication method are also disclosed.

Abstract: 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.

Abstract: A product includes a container, and an indicator that is carried inside the container and that exhibits a first visible characteristic, and a second, different visible characteristic when exposed to air.

Abstract: A product includes a closure having a radially inner portion, and being removably securable to a container, and a pendant releasably coupled to the radially inner portion of the closure, and being releasable from the closure into the container upon removal of the closure from the container. A package may include the product and a container, wherein the closure is removably secured to a neck of the container to removably close the container, and the pendant is suspended from the closure in an interior of the container neck, such that when the closure is removed from the container, the pendant releases from the closure and drops into the container and is non-removably carried therein to provide an indication that the package has been opened from its original factory sealed condition.

Abstract: A bottle comprising a neck that includes a longitudinal axis extending therethrough, a neck finish, and a radially-facing interior surface. The neck further includes one or more internal projections projecting in a radially-inwardly direction from the interior surface of the neck and axially overlapping at least a portion of the neck finish.

The data matrix comprises a plurality of optically-readable elements, one or more of which has a different dimension in a direction of curvature of the outer surface than one or more other of the elements so that the plurality of elements appear to have an expected size and shape when optically viewed in a plane perpendicular to a radial line extending from the surface.

Abstract: A product includes a container including a neck, and a ring non-removably secured to the neck of the container. The ring may be used to non-removably couple a fitment to the container and/or may be adapted irreversibly to change a characteristic of the ring that is visible from outside of the container to advise a user that the package has been opened.
