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.

Refreezing instant cold packs can damage the chemicals inside and affect their ability to provide cooling when needed. The components in the pack may not refreeze evenly or may not reach the required temperature for effective cooling after being frozen a second time. It is best to follow the manufacturer's instructions and avoid refreezing instant cold packs for optimal performance.
Instant cold packs typically reach temperatures around 32-41 degrees Fahrenheit (0-5 degrees Celsius) when activated. This temperature drop occurs quickly due to a chemical reaction that absorbs heat from the surroundings, making the pack feel cold to the touch.
Cold packs can be found at most pharmacies, drugstores, and supermarkets in the first aid aisle. They are also available online through various retailers.
A flame cannot be any cold but always hot even at the first instant it is lit.
Instant cold packs cannot be reused once they are activated. The chemical makeup inside the package was created for one time use.

Hand warmers and instant cold packs can be effectively utilized for temperature regulation in outdoor activities by activating them and placing them in pockets or gloves for warmth, or on the body for cooling. Hand warmers provide heat for cold weather, while instant cold packs can reduce body temperature in hot weather or treat injuries.

Millions of instant cold packs are used each year for various purposes like first aid, sports injuries, and medical treatments. The exact number can vary depending on the demand and usage in different industries and regions.

Cold packs can be purchased at most big box stores such as Walmart or Target in their first aid section. They are commonly known as ice packs where one can either break the bag to make instant cold to treat injuries or they can be shaken to create the same effect.

Ammonium nitrate is commonly used as a high-nitrogen fertilizer and as an explosive in mining and construction. It can also be found in cold packs used for first aid, and in some types of instant cold packs due to its endothermic properties.

Ammonium nitrate can be found in agriculture supply stores as a fertilizer, in some cold packs for injuries, and in some explosives used for mining and construction. It is important to handle and store ammonium nitrate carefully due to its potential for hazardous reactions.
You can find reusable instant heat packs at most drugstores or online retailers. Look for packs that can be reheated multiple times by boiling or microwaving.
