| Zusammenfassung: | A time-temperature indication device includes a first reservoir having a fluid disposed therein, and a capillary tube. The capillary tube is disposed proximate to the first reservoir to receive fluid from the first reservoir responsive to changes in viscosity of the fluid based on changes in temperature. The capillary tube restricts flow of the fluid out of the first reservoir into the capillary tube to enable fluid flow only in a single direction. |
