Abstract

Defrosting sensor-marker for frozen products. For clearly and irreversibly indicating a defrosted state in frozen products such as foodstuffs, vaccines and the like, a sensor is provided, which has two parts 1 and 2 mutually and hermetically connectable with chambers 4 and 5 open at their ends that lie contiguously and are intended to contain, respectively, a liquid with a freezing point close to 0 degree C and a reservoir of colourant 9 soluble in this liquid. A flexible plug 10 for blocking up the chamber 4 containing the liquid is provided. The expansion produced by the freezing of the liquid expels the plug 10 under pressure, in such a way that the aforementioned chambers 4 and 5 are in communication. Subsequent defrosting causes the colourant to dissolve, so that the sensor-marker acquires a bright colouration.
