First-use cooling device

Abstract

This product is a neck cooling device for cooling the user's neck, and is provided with eight inwardly expanding storage compartments. The cooling effect is achieved by housing a phase-change material (PCM) in these compartments. The neck cooling device of this product has a C-shaped curve due to the incorporation of a flexible core material inside the strip-shaped body shown in the "Reference Diagram Showing the Expanded State". As shown in the "AA Cross-Sectional View", the flexible core material is embedded along almost the entire length of the strip-shaped body, allowing for size adjustment to suit the user's neck size and adjustment of the degree of contact.
