<p>PURPOSE: To easily check the extent of moisture absorption and a saturated state by forming a container in such a manner that the increase in the volume due to increase in the amt. of moisture absorbed and therefore, the increase in the thickness of the container can be detected by visually checking the movement of pleats through a window formed on the upper surface of the container. CONSTITUTION: In this moisture absorbing structure the volume of a moisture absorbing compsn. 6 included in the container increased with the increase in the amt. of moisture absorbed, and therefore, the thickness of the structure body increases. With the increase in the thickness, the angle of the side face 1 increases and the position of pleats 5 on the upper end of the side face 1 moves to the inside parallel to the upper surface 4. This movement is visually checked through an opening 3. Thus, the time for exchange can be easily judged by visual checking.</p> |
