JPH10220962A - Drying agent bag with humidity displaying member - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a humidity displaying element to be used together with a drying agent bag from being forgotten to be loaded in the bag. SOLUTION: A drying agent bag 1 having a humidity displaying member is comprised of a drying agent bag 4 having a drying agent enclosed in an aeration bag 2 and a humidity displaying member 5 arranged at an outer surface of the aeration bag 2 so as to display a surrounding humidity. The humidity displaying member 5 is printed on laminated papers 6 with printing ink containing cobalt chloride. Each of the laminated papers 6 is provided with one humidity displaying member 5. In the case that a surrounding humidity, i.e., a relative humidity is less than 40%, for example, its color is changed into blue and in turn when the relative humidity reaches 40%, the color is changed into pink.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desiccant bag, that is, a desiccant bag in which a desiccant is sealed in a breathable bag, to which a humidity indicator is attached.

[0002]

2. Description of the Related Art Conventionally, in a merchandise storage system, in order to protect the merchandise from moisture, for example, a humidity indicator is mounted together with the merchandise and a desiccant bag in a transparent storage container. The humidity indicator has a function of detecting the humidity in the storage container and, for example, notifying the replacement time of the desiccant by a color change.

[0003]

However, conventionally,
Since the desiccant bag and the humidity indicator are separate objects, there is a problem that the attachment of the accessory humidity indicator may sometimes be forgotten, and the storage and handling thereof may be poor.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a desiccant bag capable of solving the above-mentioned conventional problems at once.

[0005] To achieve the above object, according to the present invention,
There is provided a desiccant bag with a humidity indicator including a desiccant bag in which a desiccant is sealed in a breathable bag, and a humidity indicator provided on an outer surface of the breathable bag and indicating ambient humidity.

By integrating the desiccant bag and the humidity indicator as described above, it is possible to prevent forgetting to insert the humidity indicator, and to improve the storage and handling thereof.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A desiccant bag 1 with a humidity indicator shown in FIGS. 1 and 2 is provided on a desiccant bag 4 in which a powdery desiccant 3 is enclosed in a breathable bag 2 and on the outer surface of the breathable bag 2. And a humidity indicator 5 for displaying the surrounding humidity.

The air-permeable bag 2 is obtained by heat-sealing the outer peripheral portions of two square laminated papers 6 having air permeability.

The humidity indicator 5 is printed on a laminate paper 6 using a printing ink containing cobalt chloride. In the illustrated example, one humidity indicator 5 is provided on each laminated paper 6.
The humidity indicator 5 is blue when the ambient humidity, that is, the relative humidity is less than 40%, for example, and turns pink when the relative humidity reaches 40%.

The desiccant bag 1 with the humidity indicator constructed as described above is required to be stored in a dry state.
For example, it is placed in a transparent storage container together with electronic components.
If the desiccant 3 is in the active state and the relative humidity in the storage container is, for example, less than 40%, the humidity indicator 5
Exhibits blue B as shown in FIG. On the other hand, desiccant 3
When the relative humidity in the storage container reaches 40%, the humidity indicator 5 changes to pink P as shown in FIG. As a result, the electronic component manager knows that it is time to replace the desiccant 3, and replaces the old desiccant bag 1 with humidity indicator with a new one.

FIG. 4 shows another embodiment, in which a humidity indicator 5 is provided.
Is printed on a backing sheet 7 with an adhesive which easily absorbs moisture, and the backing sheet 7 is attached to the outer surface of the breathable bag 2. With this configuration, when the humidity indicator 5 is damaged, a new one may be simply replaced, and the present invention can be easily configured using the existing desiccant bag 4.

[0012] Figure 5 shows yet another embodiment, this embodiment, a plurality of color change at different relative humidity, for example, three humidity display body 5 ₁ to 5 ₃ those provided side by breathable bag 2 an outer surface It is. In this case, the humidity display body 5 ₁ at the left end in the 30% relative humidity, the humidity display body 5 ₂ in the center relative humidity 40
% In, the right end of the humidity display member ₃ is configured to change color, respectively 50% relative humidity.

[0013] Thus, warns that humidity is increasing with the left end of the color change of the humidity indicating member 5 _1, also the replacement time of the same drying agent 3 at the center of the color change of the humidity indicating member 5 ₂ came I know that, further at the right end of the color change of the humidity display member _3, can emit for example the inspection order of the electronic components.

[0014]

According to the present invention, since the humidity indicator is provided in the desiccant bag, forgetting to insert the humidity indicator can be reliably prevented. The handleability can be improved.
