    • The invention relates to devices for indicating the history of products, e.g., with regard to the temperature progression. The device according to the invention comprises a covering layer, an indicator layer, an activator layer, and an optional delaying layer. By means of heating, moisture is released, which, in the case of some embodiments, migrates first into the delaying layer and then into the activator layer. There, an activator is mobilized and migrates together with the moisture into the indicator layer. By interaction of the indicator with the activator in the presence of moisture, a color conversion occurs, which indicates the exceedance of the critical temperature. The invention further relates to methods for producing the device according to the invention and to applications of the device according to the invention, e.g., in the temperature monitoring of sensitive products.
    • 本发明涉及用于指示产品历史的装置,例如关于温度进展的装置。 根据本发明的装置包括覆盖层,指示剂层,活化剂层和可选的延迟层。 借助于加热,水分被释放,在一些实施例中,水分首先迁移到延迟层中,然后迁移到激活层中。 在那里,活化剂被动员并与湿气一起迁移到指示层中。 通过指示剂与活化剂在湿气存在下相互作用,发生颜色转换,这表明超过了临界温度。 本发明还涉及用于制造根据本发明的装置的方法以及根据本发明的装置的应用,例如用于敏感产品的温度监测。

    • A freeze indicator including an indicator dispersion is described herein. Such an indicator dispersion can include: a liquid medium and particles of a colored indicator agent dispersed in the liquid medium. The colored indicator agent particles having an inherent color; wherein the indicator dispersion exhibits the inherent color of the colored indicator agent particles after freezing and is configured to have a less colored appearance before freezing and wherein light scattering masks the inherent color of the colored indicator agent particles before freezing. Some indicator dispersions can be free of color-changing chemical co-reactants. These freeze indicators can be small, have a low cost, and have a simple configuration.
    • 本文描述了包括指示剂分散体的冷冻指示剂。 这种指示剂分散体可以包括:液体介质和分散在液体介质中的着色指示剂颗粒。 具有固有颜色的着色指示剂颗粒; 其中所述指示剂分散体在冷冻后显示着色指示剂颗粒的固有颜色,并且被构造成在冷冻之前具有较少着色的外观,并且其中光散射在冷冻之前遮蔽着色指示剂颗粒的固有颜色。 一些指示剂分散体可以没有颜色变化的化学共反应物。 这些冻结指标可以很小,成本低,配置简单。
