Title:
BOTTLE TYPE COLD HEAT PACK
Document Type and Number:
WIPO Patent Application WO/2021/167174
Kind Code:
A1
Abstract:
The present invention provides a bottle type cold heat pack comprising a case, which: has a storage space formed therein to store a refrigerant composed of a phase change material (PCM), the phase of which varies according to temperature; has a front surface and a rear surface, the widths of which are wider than that of the side surface thereof; and has a rectangular hexahedral shape formed through the front surface and rear surface and curved in the forward and backward directions. Accordingly, when multiple cold heat packs are stacked and frozen, the curved shape of the case of each of the cold heat packs enables the edge portions of cold heat packs disposed in the middle or lower portion of the stack of the packs to be also exposed to the outside, thereby showing an advantage of increasing the freezing speed.
