An economically fabricated trigger for initiating crystallization of supercooled solutions in flexible plastic containers, the trigger comprising a thin substantially imperforate metallic strip having a perimeter bounding a generally dish-shaped or concave portion, the strip further having a plurality of spaced, generally parallel, generally V-shaped elongated grooves formed inwardly from the perimeter, the strip being imperforate at the groove, with the centermost portion substantially free of grooves, the strip having two configurations between which it is distortable or bendable with snap-displacement causing the initiation of progressive exothermic crystallization of said salt in the solution, the strip metal being typically impacted during fabrication to impact orient the molecular structure so as to aid the functioning of the disc or strip to produce or initiate crystallization.
For use in initiating crystallization of a supercooled salt solution, the combination that includes a flexible container containing said solution, and an improved trigger located in the container in contact with the solution, the trigger comprising:
For use in initiating crystallization of a supercooled salt solution in a flexible container containing said solution, an improved trigger to be located in the container in contact with the solution, the trigger comprising:
For use in initiating crystallization of a supercooled salt solution in a flexible container containing said solution, an improved trigger to be located in the container in contact with the solution, the trigger comprising:
The method of forming an improved trigger for use in initiating crystallization of a supercooled salt solution in a flexible container containing said solution, the improved trigger to be located in the container in contact with the solution, the method comprising:
