Beschreibung
Zusammenfassung:	A time duration of end of product life indicator is disclosed which utilizes a volatile dye coated or impregnated into a substrate or carrier. The dye evaporates as a volatile component of the product evaporates thereby changing the color of the substrate or carrier. The consumer is alerted to the depletion of the volatile component of the product when the substrate or carrier changes from a colored or dyed state to an uncolored state. As a result, a visual time duration or end of product life indicator is provided. L'invention concerne un indicateur de durée de vie et de fin d'utilisation d'un produit mettant en application un colorant volatil revêtant ou imprégnant un substrat ou un support. Ce colorant s'évapore simultanément à l'évaporation d'un constituant volatil du produit, ce qui modifie la couleur du substrat ou du support. Ceci permet d'indiquer au consommateur que le produit s'appauvrit en constituant volatil quand le substrat ou le support passe d'un état de coloration à un état incolore. De ce fait, l'expiration de la durée de vie du produit peut être indiquée visuellement.
