WATER-ABSORBENT PAD
First Claim
1. A cooling/heating water-absorbent pad, wherein:
- a water-absorbent sheet made of a material containing water-absorbent polymer is inserted in a planate bag made of impermeable cloth or sheet having a closed periphery;
the impermeable cloth or sheet and the water-absorbent sheet are stitched together such that the impermeable cloth or sheet and the water-absorbent sheet are divided into a plurality of areas in a planar view; and
water is absorbed into the water-absorbent sheet only via holes made by the stitching and by a capillarity action of a thread piercing through the water-absorbent sheet.

Abstract
It is an object of the present invention to provide a water-absorbent pad that is made of impermeable cloth or sheet, that is capable of absorbing water when needed and that effectively cools and heats a human face, neck, head and the like. A cooling/heating water-absorbent pad, wherein a water-absorbent sheet made of a material containing water-absorbent polymer is inserted in a planate bag made of impermeable cloth having a closed periphery; the impermeable cloth and the water-absorbent sheet are stitched together such that the impermeable cloth and the water-absorbent sheet are divided into a plurality of areas in a planar view; and water is absorbed into the water-absorbent sheet through a channel formed at the stitched portion. In this moment, water is absorbed into the water-absorbent sheet only via holes made by the stitching and by a capillary action of a thread piercing through the water-absorbent sheet. The water-absorbent sheet is preferably made of non-woven cloth containing water-absorbent polymer. The impermeable cloth may have a water-repellent surface.
