Abstract
A pack with Super Absorbent Material (SAM) inside and without refrigerant fluid inside. A system for dispensing a cold pack including a filling unit for taking in a waterproof SAM pack with SAM inside and without refrigerant fluid inside and adding refrigerant fluid to an inside of the SAM pack, producing a refrigerant pack. Apparatus for producing a cold pack including a SAM source, a source of refrigerant fluid, a bag filler for filling a bag with a mixture of SAM and refrigerant fluid, producing a refrigerant pack, and a cooler for cooling the refrigerant pack, thereby producing a cold pack. Related apparatus and methods are also described.
Claims30
A system for dispensing a cold pack comprising:
- a filling unit for taking in a bag and adding refrigerant fluid to an inside of the bag, producing a refrigerant pack;
- and
- a cooling unit for cooling the refrigerant pack, producing a cold pack,
- wherein the bag comprises a completely sealed and waterproof SAM bag with SAM sealed and waterproofed inside and without refrigerant fluid inside, and wherein said bag is configured to be re-sealed by heat sealing after puncturing said bag;
- wherein said puncturing allows the SAM pack to be injected with refrigerant fluid via the puncture;
- and
- wherein said SAM pack has a cavity for containing said SAM, and said cavity is waterproof.
A method of providing a cold pack comprising:
- providing a bag;
- adding refrigerant fluid to an inside of the bag, thereby producing a refrigerant pack;
- sealing the refrigerant pack;
- cooling the refrigerant pack, thereby producing a cold pack;
- and
- providing the cold pack,
- wherein the bag comprises a completely sealed and waterproof SAM bag with SAM sealed and waterproofed inside and without refrigerant fluid inside, wherein said bag is configured to be re-sealed by heat sealing after puncturing said bag;
- wherein said puncturing allows the SAM pack to be injected with refrigerant fluid via the puncture;
- wherein said SAM pack has a cavity for containing said SAM, and said cavity is waterproof.
A system for dispensing a refrigerant pack comprising:
- providing a sealed bag;
- puncturing said sealed bag and injecting refrigerant fluid to an inside of the bag, thereby producing a refrigerant pack;
- and
- re-sealing the refrigerant pack by heat sealing,
- wherein the filling unit comprises an injector for injecting the refrigerant fluid to the inside of the bag,
- wherein the sealed bag comprises a completely sealed and waterproof SAM bag with SAM sealed and waterproofed inside and without refrigerant fluid inside;
- wherein said SAM pack has a cavity for containing said SAM, and said cavity is waterproof.
A completely sealed, closed, and waterproof SAM pack with SAM sealed and waterproofed inside and without refrigerant fluid inside, wherein said SAM pack is configured to be re-sealed by heat sealing after puncturing said SAM pack;
- wherein said puncturing allows the SAM pack to be injected with refrigerant fluid via the puncture;
- wherein said SAM pack has a cavity for containing said SAM, and said cavity is waterproof.
A method of producing a waterproof SAM pack comprising:
- forming a pack of waterproof material;
- adding SAM to the pack without adding refrigerant fluid, producing a SAM pack;
- and
- sealing the SAM pack closed so the SAM pack is completely sealed and waterproof;
- wherein the SAM pack comprises a completely sealed and waterproof SAM bag with SAM sealed and waterproofed inside and without refrigerant fluid inside,
- wherein said SAM pack is configured to be re-sealed by heat sealing after puncturing said SAM pack;
- wherein said puncturing allows the SAM pack to be injected with refrigerant fluid via the puncture;
- wherein said SAM pack has a cavity for containing said SAM, and said cavity is waterproof.
