The first of the instant cold packs was a liquid-type invented by Albert A. Robbins and patented August 11, 1959. Robbins' "Chemical Freezing Package" involved and outer pouch containing two separate compartments for water and ammonium nitrate that would mix and freeze when the user split a perforation between the two - say by hitting or snapping the package as we would with the modern variety.
Robbins' patent was assigned to Kwik-Kold of America. Parent company Cardinal Health continues to market this, and the more recently invented gel-type cold packs, to this day.
