ABSTRACT:
This relates to a color change system to be incorporated in a flexing area of an end panel of a closure. The color change system includes a dark background coating on a flexing portion of the closure end panel to which there is bonded by way of an adhesive such as a varnish, ink or coating a brittle layer which due to the flipping action of the flexing portion of the end panel will fracture. The brittle layer is preferably of a light color and is colored utilizing a fluorescent dye. The combination of the background color and the fluorescent color of the brittle layer produces a first color in the original closure and when the end panel flexes and the brittle layer fractures to not only crack but also tear apart or delaminate from itself, to reflect its own light color much more brilliantly, the color of the color change system drastically changes to indicate tampering. This color change is irreversible. The color change system may also include a message indicia.
