There are many ways to facilitate the cold storage but the best known method is using ice packing. There are different kind of ice packing made of dry ice and normal ice.
[003] One of the prior arts discloses a portable cold storage device which is foldable. The cold storage device comprises: a body including a receiving unit having a side portion which can be folded with a floor sheet along a first folding line and which is provided with a thermal insulator, and including a cover unit connected to said side portion and sealing the inner space of said receiving unit from the outside; a thermal insulating plate detachably disposed on the floor sheet of said receiving unit, maintaining a floor portion of said receiving unit in a constant shape, and provided with said thermal insulator so as to block the transfer of heat through said floor portion; and a cold storage portion which can be folded along a second folding line, which includes an auxiliary thermal insulator that can be detachably received in the receiving unit, which is disposed on said thermal insulating plate, which stores a coolant and items to be stored, -2-
and which thermally insulates said coolant and the items to be stored from the surroundings thereof. Easy storage is improved by reducing the space required for storage.
[004] Another prior art discloses a large cold storage container of walk-in dimensions includes a box structure having a substantially continuous inner wall and a substantially continuous outer wall, and an internal storage volume defined by the inner wall. The inner wall and the outer wall are each made of a thermoplastic or similar material and are formed by a rotational molding process. The inner and outer walls are spaced apart from each other to provide a gap that is substantially filled with a thermal insulating material.
[005] However, the prior arts fails to disclose an efficient cold storage that preserves an original condition of the material placed inside for large period of time. Also prior arts fails to maintain a sub-zero temperature without an external system but application of such systems gets limited during a long distance travel as they need continuous power supply for the same. Also most of the portable cold storage mechanisms use dry ice that hampers environment and is not permissible for carriage with human being.
[006] In the view of foregoing, there is a need for an efficient cold storage system with storage capability of large time period. Also there is a need for a cold storage system with reusable and environment friendly nature.
[007] The above mentioned shortcomings, disadvantages and problems are addressed herein, as detailed below.
