    • Time or time-temperature indicating articles are described comprising a housing enclosing: (a) a first fluid reservoir at least partially filled with a first fluid; (b) a substrate comprising a plurality of channels; (c) a second fluid reservoir in fluid communication with at least one channel of the substrate; and (d) a barrier located between the first fluid reservoir and the second fluid reservoir. The article can be manipulated at a desired point in time by opening the barrier to allow at least a portion of the fluid to flow from the first reservoir to the second reservoir and to contact at least one channel of the substrate. The article is designed to provide an indication of the progress of the fluid as it moves through the channels of the substrate.
    • 时间或时间温度指示物品被描述为包括:壳体,其包围:(a)至少部分地填充有第一流体的第一流体储存器; (b)包括多个通道的基板; (c)与所述基底的至少一个通道流体连通的第二流体储存器; 和(d)位于第一流体储存器和第二流体储存器之间的阻挡层。 可以通过打开屏障来在期望的时间点处操作制品,以允许至少一部分流体从第一储存器流动到第二储存器并且接触基板的至少一个通道。 该物品被设计成提供流体在其移动通过基底的通道时的进展的指示。
