Abstract:

A dry instant cold pack includes approximately 50 g-55 g raw chemical fill materials contained in a pouch having a water filling nozzle. The raw chemical fill material is preferably ammonium nitrate, calcium ammonium nitrate (CAN) or urea, and the bag or pouch is preferably made of PE or PE Nylon. The dry instant cold pack has lower manufacturing cost and is easy to carry, transport and store. To activate and use, the user simply adds some water through water filling nozzle to produce a cooling effect within 30 seconds. The one-way nozzle prevents the water from flowing back out of the pouch.
