Japanese Patent JPS63233770

A

A foodstuffs thawing detector device (1) comprised of a water-filled container (2) in which detection or marker means (5, 8 or 10) is maintained in a stable position by the freezing of the water in the said container (2), where the said detection means will reach a position other than the said stable position when the water in the container melts. A preferred embodiment consists in a container (2) having an interior cavity defined by frusto-pyramidal formations (3) oriented in opposed directions and joined at their smaller bases in line with a central transverse plane (4); preferably, the said formations shall have a square base, and even a truncated arrangement (6) or the like, and detection means comprised of a ball member (5 or 8) having a high specific weight, maintained on the said central transverse plane (4) by the freezing of the water. In an alternative embodiment, the container is a simple pan (9) for the water (10), and the detection means is comprised of an amount of a water-soluble colouring (11) which will be poured into the pan once the water contained therein has frozen.
