Abstract

Time or time-temperature indicating articles (2) are described comprising a housing enclosing: (a) a first fluid reservoir (14) at least partially filled with a first fluid (16); (b) a substrate (8) comprising a plurality of channels; (c) a second fluid reservoir (18) in fluid communication with at least one channel of the substrate (8); and (d) a barrier (20) located between the first fluid reservoir (14) and the second fluid reservoir (18). The article can be manipulated at a desired point in time by opening the barrier (20) to allow at least a portion of the fluid(16) to flow from the first reservoir (14) to the second reservoir (18) and to contact at least one channel of the substrate (8). The article (2) is designed to provide an indication of the progress of the fluid as it moves through the channels of the substrate (8).
