  • Patent number: 6614728
    Abstract: The present invention provides a time-temperature integrating indicator having an amorphous material in operable contact with a porous matrix, wherein the amorphous material only migrates into the porous matrix at or above a predetermined temperature. Use of the invention simplifies monitoring of the cumulative temperature exposure of the product because no additional actuation step is required. The indicator is especially useful in monitoring the cumulative time-temperature exposure of a perishable product for a short period of time at an abusive temperature.

  • Patent number: 5770283
    Abstract: A tamper-indicating label which includes (i) light-transmissive facestock, (ii) a light-transmissive imaged release coating covering a portion of the facestock so as to provide indicia, (iii) a contrast enhancement coating over the release coated surface of the facestock, and (iv) an adhesive coated upon the contrast enhancement layer where the indicia provided by the release coating is not visible until the facestock is forcibly separated from the release coating after which the indicia becomes permanently visible and the label is provided with sufficient assembly cohesive strength to keep the label together as a single unit after the facestock is separated from the release coating and the indicia is rendered visually perceptible.
