DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings, but it goes without saying that the present invention is not limited to these embodiments. This will be described in detail with reference to the drawings shown in FIGS. FIG. 1 is a side sectional view of the dehumidifier container of the present invention. FIG. 2 is a perspective view of the dehumidifier container of the present invention.

In FIG. 1, a dehumidifier container 1 comprises a substantially rectangular lid 2 and a container 3, and the lid 2 and the container 3
A flange portion 9 is formed on the entire outer periphery of the opening portion. The flange portions 9 are provided with fitting concave and convex portions 11 and 12. The partition member 7 is engaged with the upper end inside the opening of the container body 3 so that the lid body 2 and the container body 3 are aligned with each other, and are fitted and closed by fitting concave and convex portions 11 and 12 of the flange 9. The moisture absorbent 4 is stored in the lid 2 on the partition member 7 in the porous bag 10. A ventilation portion 8 is formed in the lid 2, a microporous moisture-permeable and water-permeable sheet 6 is closed by welding on the inner surface of the lid 2, and a gas barrier non-permeable material such as aluminum foil is formed on the lid surface. The wet sheet 5 is sealed by heat welding or the like in an easily opened state.

Unlike the case where the moisture-permeable and water-impermeable sheet 6 is welded to the container 3, the moisture-permeable and water-impermeable sheet 6 is welded to the opening of the lid 2. The moisture absorbent can be stored, and the container body 3 can be made smaller. Regarding the position where the moisture-permeable and water-impermeable sheet 6 is welded, it may be welded to either the inner surface or the outer surface of the lid. Plays a protective role. Further, the opening of the lid 2 may have any shape such as a whole hole or a lattice as long as it has a sufficient opening shape as a doorway for moisture.
There is no particular limitation.

The dehumidifier container 1 may be formed of a transparent or translucent synthetic resin whose inside can be seen through, and be set to a thickness small enough to hold the shape of the container for commercial purposes. The molding method can be freely selected from an injection molding method, a vacuum molding method and the like, and is not particularly limited. However, when the thickness of the container is reduced or the transparency is improved, the vacuum molding method or the like is preferable. For example, a thermoplastic plastic sheet is sandwiched between plugs and heated and softened from both sides or one side of the sheet is placed on a convex or concave mold having many small holes, and the opposite side of the mold is placed. The air is released through small holes, the sheet is brought into close contact with the mold, then cooled and taken out. It is an intermediate method between vacuum forming and hollow forming, and heat-softened sheet is vacuum formed. Instead, there is a compressed air molding method of blowing and molding with compressed air.

The dehumidifier container 1 is a resin molded product made of a transparent or translucent synthetic resin whose inside can be seen through, and examples of the resin material include polypropylene and polyethylene. Further, the container is a resin molded body having a strength capable of withstanding a load such as a desiccant and a deliquescent liquid, and is a resin molded body including the lid body 2 and the container body 3 which are as thin as possible. The thickness of the container slightly varies depending on the shape, size, or depth of the lid 2 and the container 3, but may vary from 0.1 mm to 0.1 mm.
A range of 9 mm is preferred. Further, the thickness of the container is desirably made as thin as possible, and more preferably 0.1 to 0.5 mm in consideration of the balance between the holding strength, the pressure resistance, the strength at which the container does not break or break when dropped, and the like. When it is desired to reduce the thickness of the entire container, it is desirable to make the size (volume) of the lid 2 and the container 3 close to each other. Further, depending on the purpose of use of the dehumidifier container 1 within this range,
For example, the thickness of the lid 2 may be smaller than the thickness of the container 3.

The shape of the lid 2 is concave and has a space having a volume for accommodating the moisture absorbent 4. Since the lid 2 has a function of accommodating the moisture absorbent, the size (volume) of the container 3 can be reduced.

Space volume (size) of the lid 2 and the container 3
The ratio of the space volume of the lid to the total volume of the container including the lid 2 and the container 3 is preferably 0.25 to 0.5. The setting of each space volume slightly varies depending on the presence or absence of the partition member 7, disposable, refilling, and the like.
It is desirable to determine in consideration of the moisture absorption rate and the effect on the quality of the molded product.

In order to increase the rate of moisture absorption, it is preferable to arrange the moisture absorbent 4 as close to the ventilation portion 8 of the lid 2 as possible. Is desirable. Further, in the case of a molded product having a quality, for example, vacuum forming or the like, a container having a deep bottom has a drawback that a corner portion becomes thin and poor in uniformity. Therefore, it is desirable to make the container as shallow as possible. In this case, the space volume of the container 3 can be reduced by increasing the space volume of the lid 2. For example, the bottom of the container may be made shallow by reducing the volume of the space below the partition member 7 so that the contained hygroscopic agent 4 is deliquescent and a saturated solution of the dissolved liquid is exposed on the partition member 7. It is possible to further reduce the size of the dehumidifier container.

The lid 2 provided with the ventilation section 8 and the container 3 are closed together. It is used in a state where it cannot be opened by heat welding or in a state where it can be opened by fitting or pinching. For example, it is preferable that the disposable type is closed in an unopenable state, and the refillable type is closed in an openable state.

It is possible to print characters such as product names, manuals and the like, pictures and the like on the sheet plate before molding, and it is not necessary to use a conventional label, and it is possible to further enhance the merchantability. Furthermore, since the inside can be seen through and there is no label, it is easy to see the moisture absorption state.

The hygroscopic agent 4 is a deliquescent substance such as calcium chloride, magnesium chloride, and potassium acetate. In particular, calcium chloride and magnesium chloride are preferable from the viewpoints of hygroscopicity, cost, and the like. In addition to the deliquescent substance, for example, non-liquefied silica gel, activated carbon, white carbon, a water-absorbing polymer, or the like may be used as the desiccant 4 alone or in combination with the deliquescent substance depending on the purpose of use. Further, the place where the dehumidifier container is used has problems with odors, pests, bacteria, fungi, etc., and in addition to the above-mentioned desiccants, deodorants, deodorants, fragrances, insect repellents, disinfectants, fungicides, etc. It is also effective to use it in combination with a substance having a function such as a fungicide.

The outer surface of the lid 2 is sealed with a moisture-impermeable sheet 5. Examples of the moisture-impermeable sheet 5 include a gas barrier film made of plastic having gas barrier properties and an aluminum foil. Then, a sheet having an easy-open property that is easily peeled off at the time of use is preferable.

The inner ventilation surface of the lid 2 is closed by a moisture-permeable and water-impermeable sheet 6. The moisture-permeable and water-permeable sheet 6 allows moisture and air to pass, but not water. For example, a material obtained by physically or chemically treating a polyolefin resin, a polyamide resin, a polyvinyl chloride resin, or the like to form minute pores can be used. In addition, the blockage is ultrasonic welding,
It is fixed by a welding method such as hot plate welding, high frequency welding and hot air welding.

The partition member 7 is made of a porous film, sheet,
It is made of plastics such as nets, non-woven fabrics, woven fabrics, synthetic papers, etc. and is responsible for arranging and holding the hygroscopic agent 4 inside the lid 2 and flowing out water generated by deliquescence without the hygroscopic agent 4 falling into the container 3. It has a function to do. Further, the partition member 7 may have a conventional thick plate shape, but it is preferable to form the partition member 7 into a thin shape having strength enough to withstand the weight of the hygroscopic agent from the viewpoint of reducing the amount of waste. Further, when the lid body and the container body 3 are fixed, the thin partition member 7 can be heat-welded together, which is preferable.

FIG. 3 is a side sectional view showing a second embodiment of the present invention. FIG. 4 is a side sectional view showing a third embodiment of the present invention. The one shown in FIG. 3 includes an elongated rectangular lid 2 and a container 3, and the partition member 7 has an encircling shape and accommodates the particulate hygroscopic agent 4 therein. The moisture-impermeable sheet 5 is thermally welded to the upper surface of the lid 2. Forming fitting irregularities on the surfaces of both flanges 9 of the lid 2 and the container 3 and fitting them together,
Can be opened. What is shown in FIG. 4 is an elongated rectangular dehumidifier container 1 which has no partition member 7, forms convex portions at several places on the bottom surface of the container body, raises the bottom, and raises the porous bag 10 above it. The stored moisture absorbent 4 is stored. The two flanges 9 of the lid 2 and the container 3 are heat-welded. Further, the porous bag 10 for storing the moisture absorbent 4 shown in this figure may be a film bag made of a water-soluble resin or the like.

Although the partition member 7 is used for the purpose of being disposed close to the ventilation portion for increasing the moisture absorption rate of the moisture absorbent, the moisture absorption of the moisture absorbent 4 can be performed without using the partition member as shown in FIG. Speed can be increased. Further, even in the case of a flat container shape, a side ventilation container, use of a high moisture absorbent, physical dehumidification, and the like, the performance such as the moisture absorption rate of the contained moisture absorbent 4 can be sufficiently exhibited without using a partition member.

Further, the shape of the dehumidifier container 1 is not limited to a square shape, but may be any shape such as a round shape, a triangular shape, and a polygonal shape.

The storage form of the moisture absorbent 4 can be stored in a bag 10 as shown in FIGS. As bag material,
Examples include paper, nonwoven fabric, resin film, and net. The shape of the partition member 7 is not limited to a plate shape, but may be concave as shown in FIG.
