Abstract
Abstract A cap element mainly composed of a three-layer fabric, the three-layer fabric member including: a mesh-like front surface fabric; a waterproof back surface fabric; and a non-woven fabric formed of water absorptive high molecular fibers, which is sealed between the front surface fabric and the back surface fabric. At least one of the front surface fabric and the back surface fabric may be subjected to ultraviolet ray shielding treatment, or composed of a knitted or woven fabric formed of fibers of a high molecular polymer containing an inorganic material capable of absorbing ultraviolet rays and reflecting the heat rays of the sun.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A cooling cap comprising a three-layer fabric member forming a cap body for covering a head, a peripheral length adjusting means connected to the three-layer fabric member for surrounding the head, the three-layer fabric member having a plurality of ventilation holes formed therein, the three-layer fabric member comprising: a mesh-like first surface fabric, a waterproof second surface fabric, and a non-woven fabric sealed between the first surface fabric and the second surface fabric, the non-woven fabric comprising water absorptive high molecular fibers comprising acrylic resin staples having a surface layer coated with a high molecular gel material.
Claim 2
Dependent Claim
