Abstract
A temperature indicating device having a temperature indicating portion, with a plurality of spaced zones defined therein, a temperature-sensitive material in each zone, whose material begins to undergo a change from solid to liquid state at a precise and predetermined temperature, an absorbent indicator layer on each zone, impregnated with a dye or glue soluble in said thermosensitive liquid material; and an absorbent masking layer, superimposed, having a color that contrasts with the color of the indicator layer, but operable to indicate a change of said thermosensitive material from the solid state to the liquid state thanks to the absorption of said liquid material carrying said material. Dye or pigment; characterized by a porous layer interposed between the thermosensitive material in said zone and the indicator layer associated with a zone, and an intimate contact with them, said porous layer having a volume of pores sufficient to absorb the liquid generated when the thermosensitive material partially melts ao below its melting point, but less than the total volume of the thermosensitive material in that zone when it is completely in the liquid state.
