BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifier capable of discarding only a bag containing deliquescent salts stored in a paper box after use.

[0002]

2. Description of the Related Art Heretofore, stationary dehumidifiers are contained in hard plastic containers, and most of them are disposable and are disposed of together with the containers. Also, refillable hard containers have to be discarded because they have to be discarded, which is not preferable from the viewpoint of resource saving. Since this type of container has a structure in which moisture is absorbed from one side, the rate of moisture absorption on the surface must be increased, and the production of such a container is complicated and costly.

[0003] On the other hand, the bag type is a soft package, so there is a risk of breakage. To avoid the risk of breakage, many are small and have a small amount of moisture absorption. Although paper is wound in a belt shape to prevent breakage, it has been difficult to manufacture a stationary type having a large amount of moisture absorption.

[0004]

[Problem to be Solved by the Invention] The present inventor studied a dehumidifier that can be refilled by discarding only the contents after use. As a result, the box was made of vapor-permeable cardboard and stored deliquescent salts. By storing the moisture-permeable bag (hereinafter referred to as the dehumidifier) in a box-shaped container, and disposing of the medicine-containing bag after use and renewing it, the box-shaped container can be used again and again. The inventors found that a replaceable dehumidifier was obtained, and came to the present invention.

[0005]

SUMMARY OF THE INVENTION The present invention provides a water vapor permeability of 200.
g / m ² , 24 hr, 40 ° C., RH 90% or more, weight 2
In a box-shaped container having a detachable lid formed from a cardboard of 00 g / m ² or more, deliquescent salts were stored in a bag-like material made of a non-permeable membrane having a greater moisture permeability than the cardboard. A dehumidifier capable of refilling a bag-shaped dehumidifier, wherein the dehumidifier stores a dehumidifier, and an indicator that changes its color depending on humidity is attached to an appropriate position on an outer surface of the box-shaped container.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows the dehumidifier of the present invention. A cardboard box-shaped container 1 having a removable lid 5 contains a moisture-permeable bag-like material 2 containing deliquescent salts 3. Here, the cardboard of the box-shaped container 1 and the lid 5 is 200 g / m ² , 24 hr, 40 ° C., R
H90% or more of moisture permeability. The moisture permeability is determined by the internal capacity, the saturated water absorption, the surface area of the box-shaped container, the period of use, etc., but is 200 g / m ² , 24 hr, 40 ° C., RH9
If it is less than 0%, it is insufficient as a container for a dehumidifier,
0 g or more is preferable. Further, the thickness of the cardboard is required to be 200 g / m ² or more. If it is less than 200 g / m ² , the strength is insufficient due to shape retention of the container and the like, and it is preferably 300 g / m ² or more. Manila balls, coated balls,
Cardboard or the like can be used. In addition, not only cardboard but also a container (pillar cup) whose frame is made of plastic and the periphery of which is made of cardboard can be used.

A lid 5 is provided with the same material as the cardboard box 1. The lid 5 is preferably opened when refilling the dehumidifier and closed during use, so that it can be removably fitted. Any kind of attachment and detachment method such as an ink cage type can be used. .

Further, the cardboard container 1 may become thicker due to moisture and the strength may be reduced due to the weight of the contents. Therefore, it is desirable to perform a water-repellent treatment on the inner surface, particularly the lower portion, of the container 1. The water repellent treatment applied here
It is preferable to infiltrate a liquid water-repellent resin such as fluorine or silicon or a diluted solution thereof into the inner surface, or to adhere a water-repellent nonwoven fabric such as polyethylene or polypropylene to the inner surface.

There are various deliquescent salts used in the present invention, such as calcium chloride and magnesium chloride, but calcium chloride is inexpensive and common.

The moisture-permeable, water-impermeable membrane containing deliquescent salts is 1000 to 8000 g / m ² , 24 hr, 40 ° C., R
A film having a moisture permeability of about 90% is used, such as a microporous film obtained by stretching a film from a thermoplastic polyurethane film or a filler such as polyethylene and ultrafine powder CaCO ₃ , or further immersing the film in hydrochloric acid or the like. Is preferred. Bags of appropriate size are made from these films, and deliquescent salts are stored and used as dehumidifiers. Although the dehumidifier depends on the humidity of the outside air, if it is absorbed for one to six months, it becomes almost saturated, and cannot be used any more. Therefore, the dehumidifier is discarded as a bag.

Since the inside of the box-shaped container 1 made of cardboard cannot be seen from the outside, an indicator that changes its color due to humidity, such as cobalt test paper, is attached to an appropriate location on the outer surface of the container 1 to see the end point of the dehumidifier. The humidity of the outside air permeates through the cardboard container into the container. Since the moisture permeability of the bag in the container is larger than that of the cardboard container, the moisture passing through the container immediately permeates into the bag, but when the deliquescent salts in the bag absorb moisture and become saturated, the inside of the bag becomes The humidity increases, and also outside the bag, ie inside the cardboard container, which flows back and reacts to the indicator and discolors. This occurs because the moisture permeability of the bag-shaped material is higher than that of the cardboard container.The humidity in the container does not increase until the humidity in the bag is saturated. Will not react.

This cobalt test paper is affixed to the outer surface of the container with a moisture-impermeable transparent tape to prevent sticking and prevent discoloration due to the humidity of the outside air.

Although the present invention has been described with reference to the drawings and explanations based on a rectangular parallelepiped box made of cardboard, the present invention is not limited to a rectangular parallelepiped, and a cylindrical box may be used. Needless to say, any shape can be used as long as the shape can be set.

[0014]

[Effects of the Invention] According to the present invention, a box is made from cardboard having properties such as a specific moisture permeability, and a dehumidifier containing deliquescent salts is stored in a bag of a specific film. The amount and the rate of moisture absorption can be set widely, and only the contents can be discarded after use and refilled with a new one.
It is an economically advantageous dehumidifier.
