ある。The functions of this sheet used in these fields include: 1. Leak prevention, dehumidification (raincoats, disposable diapers, etc.), 2. Component distribution control, (fragrances, insect repellents, etc.).
本発明は水蒸気の透過性と、水の蒸発熱とを組み合わせ
て冷却用具に利用したものである。The present invention utilizes a combination of water vapor permeability and water evaporation heat in a cooling device.
水の蒸発熱を利用した冷却方法は、クーリングタワー、
冷房機、或いは昔から家庭で行われている打ち水等々に
利用されている。Cooling methods that utilize the heat of evaporation of water include cooling towers,
It is used in air conditioners, and for sprinkling water, which has been practiced at home since ancient times.
しかし、水蒸気透過性シートを水と組み合わせて冷却用
具に用いる提案はなく、本発明は適度な透過度を持つシ
ートを利用することにより、実用効果の高い冷却用具が
提供出来ることを見出した事に基づ（ものである。However, there has been no proposal to use a water vapor permeable sheet in combination with water for a cooling device, and the present invention has discovered that by using a sheet with appropriate permeability, a cooling device with high practical effects can be provided. It is based on something.
本発明に用いる水蒸気透過性のシートは、例えば放電に

類を限定するものではない。The water vapor permeable sheet used in the present invention is a porous sheet produced by, for example, a method of making holes in a film by electric discharge, a method of stretching a film mixed with a filler, a method of removing a filler from a film mixed with a filler, or a urethane sheet. There are no limitations on the type, such as non-porous and permeable sheets.
本発明に於ける水蒸気の透湿度はＪＩＳ ２０２０８の
防湿包装材料の透湿度試験方法により定義される。即ち

１平方メートル当たりで換算した量で表わされる。The water vapor permeability in the present invention is defined by the JIS 20208 moisture permeability test method for moisture-proof packaging materials. That is, at 40°C, two spaces (A) relative humidity 90% and (B) moisture absorbent (anhydrous calcium chloride) are separated by a moisture permeable film, and the amount of water passing through the film from A to B is measured for 24 hours.
It is expressed as an amount converted per square meter.

ておけば、かなり長時間（少なくとも１日）効果が持続
する。The cooling device according to the present invention exhibits a mild cooling effect using only water, even without the use of ice, and if an appropriate amount of water is contained, the effect lasts for quite a long time (at least one day).
本発明による冷却用具は、氷のう、氷枕だけでなく、フ
トン、座ブトン、或いは大きな空間（例えば部屋）の冷
房用に使用することが出来る。The cooling device according to the present invention can be used not only as an ice pack or an ice pillow, but also as a futon, a seat button, or for cooling a large space (for example, a room).
以下実施例により本発明を更に詳しく説明する。 The present invention will be explained in more detail with reference to Examples below.
実施例１及び比較例１
