<p>PURPOSE:To constantly absorb moisture and to prevent oozing over a long period by providing an air-permeable part sealed with a water-repellent-treated moisture-permeable film at a part of a shaped vessel and sealing a moisture- absorbing chemical into the vessel. CONSTITUTION:A vessel 5 is, manufactured by shaping, an air-permeable part 4 is provided on the vessel, and the lower side of the air-permeable part 4 is sealed with a water-repellent moisture-permeable film 2 and the upper side with an air-retainable protective material 1. Consequently, air passes through the part, and its moisture is absorbed by a moisture-absorbing chemical 3 filled in the vessel. When such a film is used, dew condensation and oozing are not caused, and hence the device can be used for the clothing, fur, etc.</p> |
