About.

The dehumidifier contains a deliquescent dehumidifying agent in a container body having an upper surface opening. The top opening is covered with a moisture-permeable and water-impermeable sheet (hereinafter simply referred to as “moisture-permeable sheet”), and a sealing sheet (moisture-proof sheet) is detachably attached to the moisture-permeable sheet. (For example, see Patent Document 1 and Patent Document 2).
Incidentally, the moisture-permeable sheet allows moisture and air to pass through, but does not allow water to pass through. For example, micro holes are processed in polyolefin resin, polyamide resin, polyvinyl chloride resin, etc., and adhesion to the upper surface opening of the container body is ultrasonic welding, high frequency welding, hot plate welding, thermal welding. For example, the opening edge (flange) is formed.
On the other hand, the sealing sheet is impermeable to moisture, air and water. For example, it is made of a gas barrier film such as an aluminum sheet or polypropylene, and is detachably attached to the surface of the moisture permeable sheet, and can be easily peeled off from the surface of the moisture permeable sheet when used by the purchaser. It is like that.

  Dehumidifiers configured in this way are widely used in closets, chests, clogs and other storage spaces, etc., and absorb moisture in the air with a deliquescent dehumidifier to reduce the humidity in the space and keep the humidity low. .
