COOLING GARMENT
Document Type and Number:
WIPO Patent Application WO/2023/084872
Kind Code:
A1
Abstract:
[Problem] To provide a cooling garment of a cooling-liquid-circulating type that is capable of maintaining comfortable cooling effects over a long time while the cooling garment unlikely bulks, does not cause a sense of heaviness, and can be produced at low cost. [Solution] On the inner surface of a cooling vest 1, a tube 67 is laid in an exposed state. On the outer surface side of a back portion 5 of the cooling vest 1, a storage unit 55 is attached, and a frozen PET plastic bottle P is stored therein. The tube 67 is filled with water W. By the operation of a pump 69, the water W in the tube 67 flows into the storage unit 55 as water droplets D from the upper side, is cooled in the process of hitting on the outer surface of the PET plastic bottle and dripping down while sliding, and returns to the inside of the tube 67 from an outflow port on the lower side. Ice K inside the PET plastic bottle P melts, but the ice K remains on the upper side until the end. Since only a small volume of water W is needed, the vest is lightweight and also has high durability. Moreover, the cooling effect resulting from contact with the PET plastic bottle P can be maintained over a relatively long period. Furthermore, melted beverage inside the PET plastic bottle can be used for hydration.
