BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage cabinet having a humidity control function.

[0002]

2. Description of the Related Art In a book or the like, the paper used in accordance with a change in humidity expands and contracts, and the strength of the paper also changes remarkably. If this is repeated for a long period of time, deterioration is inevitable. In addition, it is necessary to avoid changes in humidity as much as possible to prevent deterioration of works of art such as scrolls and paintings.

For this reason, paulownia has long been used as a material for appropriately adjusting the humidity, and by storing the goods in a paulownia box, the influence of humidity change in the outside world was reduced to prevent deterioration.

However, since the paulownia box is very expensive, it has been common in recent years to place a humidity control agent such as silica gel or alumina gel in a perforated bag and place it in a storage box. As an example of a storage cabinet for cultural assets having the above (Japanese Patent Laid-Open No. 2-85183), there is proposed a paper core for a panel having a moisture absorption / dehumidification performance, which is arranged on the inner peripheral surface of the container.

[0005]

[Problems to be Solved] In the former example in which the humidity control agent is simply put in a perforated bag and placed in the storage cabinet, the surface area of the humidity control agent is small and ineffective, and the humidity control agent is placed in a space where The storage space becomes smaller, which hinders the storage of objects.

In the latter example in which the paper core for the panel is arranged on the inner peripheral surface of the container, no sealing material is interposed between the door and the opening of the cabinet body, so that sufficient airtightness should be maintained. However, it is necessary to use a large amount of paper core to compensate for this, and depending on the case, even if the paper core is placed on the inner peripheral surface of the container or the lower surface of the shelf, a sufficient humidity control function can be achieved. There are times when you can't In addition, if the airtightness is to be maintained, the structure becomes complicated and sturdy, and the cost becomes high.

The present invention has been made in view of the above points, and an object of the present invention is to provide a low-cost humidity storage cabinet capable of performing a sufficient humidity control function with an appropriate amount of humidity control board. ..

[0008]

In order to achieve the above object, the present invention provides a storage box in which a front opening of a box can be opened and closed by an opening door pivotally supporting a suspension base by a hinge or the like. A humidity control board was stretched on at least a part of the inner surface of the storage or the lower surface of the shelf, and packing was provided over the entire circumference between the humidity control board and the peripheral edge of the door.

[0009] With a simple structure in which packing is interposed between the peripheral edge of the hinged door and the peripheral edge of the box body, a sufficient humidity control function can be obtained simply by placing an appropriate amount of humidity control board on the inner surface of the storage cabinet and the lower surface of the shelf board. You can configure the fulfillment vault.

By arranging the packing of the hanging base of the opening door so as to be pressed in the swinging direction of the door, it is possible to secure a sufficient shrinkage allowance, so that the airtightness can be sufficiently maintained, and the packing can be Deterioration can be prevented without causing scratches or oblique deformation. Further, by attaching a breathable plate material to the humidity control board, it is possible to prevent the stored items from directly contacting the humidity control board.
