Abstract

An apparatus with time controlled color change indication comprises an apparatus includes a disposable, limited or restricted use product and an oxygen sensing color changeable dye disposed on a portion of the apparatus, the dye being translucent or having a first color upon application and for a defined time thereafter and the dye changing color after exposure to oxygen for the defined time. For example, a packaging for containing a product for human consumption has a portion with a color changeable dye disposed thereon. The dye changes color after being exposed to oxygen for a controlled and predetermined period of time indicating that the product for human consumption should no longer be consume or has decreased in freshness, quality of taste or potency.
