Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a container for household hygroscopic agents, and more particularly to a disposable hygroscopic agent container whose main body is cardboard.

[Conventional technology]

This type of household hygroscopic agent is a deliquescent hygroscopic agent that can be easily used as a dehumidifying means such as a closet or a shoe box, and has a sufficient hygroscopic capacity.

By the way, since such hygroscopic agent causes deliquescent liquid due to absorption of moisture in the air during use, a structural container for storing the deliquescent liquid is used as a form of use for that purpose. Moreover,
When the deliquescent liquid adheres to clothing or the like, there is a risk of discoloration. Therefore, it must be taken into consideration so that the deliquescent liquid under storage does not flow out due to the container falling over or the like.

Thus, the conventional hygroscopic agent container is a box-shaped container made of synthetic resin and has a structure in which the canopy portion is opened and the opening portion is closed with a hygroscopic film made of a microporous film material. Many are used.

And, a container made of these synthetic resin containers can be reused by replacing the hygroscopic agent contained therein as a refill container, whereas recently, as a disposable container, a paper-made hygroscopic agent container. Are in practical use.

This paper container is made water-tight by attaching aluminum foil to the inner surface of the cardboard of the box material or by means such as waxing,
A constitution is employed in which a transparent window having a relatively large area is opened in a part of the four side peripheral surfaces of the formed box-shaped container, and a moisture permeable sheet is attached to the back surface of the transparent window to close it.

[Problems to be solved by the invention]

That is, according to the above-mentioned conventional container, while the synthetic resin is excellent in container strength and durability such as refilling, the cost is high for manufacturing the container, while the disposable container made of paper is costly compared to this. It is inexpensive in terms of surface, but the air recirculation part in the container is the window part, and further, when the area of this window part is expanded, the container strength decreases,
As a result of the limitation of the window area, there is a drawback that the air is not sufficiently recirculated and a strong moisture absorption ability cannot be obtained.

Therefore, an object of the present invention is to develop a hygroscopic agent container which is a low-cost paper container having a high hygroscopic capacity and which is easy to manufacture and has high mass productivity.

[Means for solving problems]

According to the present invention, the object is to form a box-shaped container main body from a material in which a microporous film sheet or a transparent polyurethane film is bonded to one side of cardboard, and peel the container main body containing the deliquescent hygroscopic composition. This can be achieved by a desiccant container that is sealed with a possible sealing material.

And, it is effective to attach a moisture absorption discoloration indicator such as cobalt chloride or to provide a functional limit display window for displaying a water level mark of the deliquescent liquid on a part of the side wall of the container main body.

[Action]

The cardboard, which is a box-shaped constituent material, functions as a shape-retaining material due to its hardness, and also functions as a moisture-absorption surface that extends over the entire circumference of the container due to its hygroscopicity.

The deliquescent composition contained in the cardboard container body absorbs water through the cardboard of the container and the microporous film sheet or transparent polyurethane film bonded to the cardboard.

The deliquescent liquid generated by water absorption is prevented by the microporous film sheet or the transparent polyurethane film, and therefore does not flow out of the container.

Then, the previous container, after measuring the joining by micro-porous film sheet or a transparent polyurethane film front surface sticking with a water-soluble glue material or partial sticking with other glue material on a cardboard mount punched into a box-folded shape, It is formed by removing the die, folding it, and substituting it with glue, and further containing the hygroscopic composition and then sealing. Therefore, according to such processing, it is possible to manufacture the moisture-permeable waterproof container that acts as described above by a mass production process by mechanical processing. Incidentally, in the case of joining the cardboard mount and the microporous film sheet or the transparent polyurethane film, it is needless to say that conventionally known means can be adopted in addition to the above-mentioned partial sticking means using the adhesive material.

The unused container is sealed with a moisture-proof film sheet or the like, and the container is used by removing the sealing material.

Next, an illustrated embodiment of the present invention will be described.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the present invention.
Is formed into a box shape by folding a cardboard 2 punched out from a mount into a box-folding shape and pasting it with glue margins 3, 3, ...
On one side of the upper surface of the box type, an ear piece 4 formed by folding back the thick paper 2 is provided, and a hanging frame 5 for hanging is provided in the central portion of the ear piece 4, while one of the front side walls of the box shape is provided. A display window 6 is opened in the portion.

As shown in the longitudinal sectional view of FIG. 2, this box-shaped container main body 1 has a microporous film sheet 7 bonded to one inner surface of the cardboard 2 and has a bulk of about 40% of its internal volume. It contains a conventionally known deliquescent hygroscopic composition 8 occupying a volume of volume.

In forming the display window 6, the window 6 is punched out in advance at a predetermined position on the mount before punching into a box-folding die, and then the microporous film sheet 7 is bonded or heated to the entire surface of one side of the mount. After joining by the sealing means, it is punched together with the microporous film sheet 7 in the box-folding type.

Therefore, the display window 6 thus formed is closed by the microporous film sheet 7, and the indicator 9 which is discolored or develops due to moisture absorption composed of cobalt chloride or the like is attached to the front side of the microporous film sheet 7 in this portion. A transparent moisture-proof film 10 is attached to the front side of the indicator. This display window 6 portion is shown in FIG.

On the other hand, it is also possible to apply the transparent polyurethane film 7 in place of the microporous film sheet 7. In this case, the state inside the container main body 1 can be visually confirmed through the window 6, so that the end area of the moisture absorption effective period region A water level reference mark 11 for discriminating the increase in the amount of the deliquescent liquid stored in 1 is attached as shown in FIG.

The entire container main body 1 configured in this way is covered with a bag-shaped hermetic seal 12, and the seal is peeled off at the time of use so that the water content in the air passes through the cardboard 2 and the microporous film sheet 7. It is absorbed by the internal deliquescent hygroscopic composition 8.

[Effect of device]

As described above, according to the container of the present invention, since the container main body is made of cardboard material, it can be manufactured at a lower cost than the conventional synthetic resin container and is effective as a disposable container. Since a microporous film sheet or a transparent polyurethane film is lined on it, moisture can be absorbed from the entire circumference of the container made of the cardboard by peeling off the sealing seal covering the container main body, and the conventional ventilation window can be used. It exhibits a stronger hygroscopic capacity than the provided paper container.

Further, according to the constitution of the container of the present invention, the cardboard and the microporous film sheet or the transparent polyurethane film are prepared by joining the microporous film sheet or the transparent polyurethane film to one side of the cardboard mount in advance and then punching it out in a box fold type. The container of the present invention is easy to manufacture and has excellent moisture absorption ability, such that a box body formed by stacking with the above can be easily constructed, and in particular, it is extremely excellent in practical use as a disposable container.

The shape of the container main body in the container of the present invention is not limited to the embodiment shown in the figure, and it can be freely selected, and the means for storing the deliquescent hygroscopic composition in this container main body is also in the container. It is needless to say that various well-known conventional modes can be adopted, such as direct use, and the use of another wrapping paper in which the quantitative amounts are summarized in advance.
