    摘要: 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.

    摘要: A display frame with a refill holder comprises a transparent block with front and rear faces. A U-shaped mounting member is attached to the rear face about an outer periphery of same. The U-shaped mounting member has an inwardly extending wall. A channel is formed in a space between the rear face and the inwardly extending wall. A protrusion is attached to the rear face of the frame, wherein the protrusion in combination with the inwardly extending wall are configured to distance the rear face from a support surface when the frame is in a substantially horizontal position and provide a substantially unimpeded air passage adjacent the rear face.
