Description

[Technical Field]

[0001] The present invention relates to a dehumidifying and deodorizing device in which, for example, a dehumidifying agent and a deodorizing agent are housed in a container. [Background technology]

[0002] Conventionally, a dehumidifying and deodorizing device known is a deodorizing and dehumidifying device in which a deliquescent dehumidifying agent and a deodorizing agent are mixed and enclosed in a bag whose entire periphery is sealed, with one side made of a moisture-permeable, water-impermeable sheet and the other side made of a moisture-impermeable, water-impermeable sheet (for example, Patent Document 1).

[0003] The deodorizing dehumidifier of Patent Document 1 takes water vapor contained in the outside air into a bag through a moisture-permeable, water-impermeable sheet and absorbs the water vapor with a desiccant. When the desiccant absorbs the water vapor, a chemical reaction causes the desiccant to deliquesce, producing an aqueous solution. The aqueous solution produced inside the bag accumulates inside the bag without passing through the moisture-permeable, water-impermeable sheet and the moisture-impermeable, water-impermeable sheet.

[0005] In the deodorizing dehumidifier of Patent Document 1, the deodorizing agent is mixed with the dehumidifying agent and contained in the bag, so it sinks in the aqueous solution produced by the deliquescence of the dehumidifying agent. As a result, the deodorizing dehumidifier of Patent Document 1 is unable to exhibit fully satisfactory deodorizing performance.

[0006] The present invention has been made in view of the above points, and has as its object to provide a dehumidifying and deodorizing device that can fully demonstrate its deodorizing performance. [Means for solving the problem]

[0007] In one embodiment of the dehumidifying and deodorizing device of the present invention, a dehumidifying agent that absorbs water vapor and deliquesces to become an aqueous solution is used. Except Wetting agent and , particle size 100 mesh or more The container body has a chemical agent mixed with an adsorbent, and a vertical wall portion having a moisture-permeable portion that allows water vapor to pass through and extending in the direction of gravity, and contains the chemical agent in an internal space sealed by the wall portion including the vertical wall portion. sucking The adhesive adheres.

[0008] The internal space of the container body is kept at a low humidity level due to the effect of the dehumidifying agent, so static electricity is easily generated. Grain size 100 mesh or more The adsorbent is attached to the inner surface of the vertical wall by static electricity. suck This allows the product to come into contact with the adhesive effectively, and fully demonstrates its deodorizing performance. [Effects of the Invention]

[Figure 4] FIG. 4 is a graph showing an example of the results of a deodorization test using the dehumidification and deodorization device of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a dehumidifying and deodorizing device 10 according to one embodiment of the present invention has a container 15 and a chemical 40 accommodated in the container 15.

[0012] The chemical 40 is, for example, a mixture of a particulate dehumidifying agent 41, a particulate adsorbent 42, and a fine powder adsorbent 43 in a predetermined ratio. The blending ratio of the particulate dehumidifying agent 41 to the adsorbents 42 and 43 is not particularly limited, but is preferably 1000:1 to 10:1 by weight, and particularly preferably 500:1 to 5:1 by weight. In this embodiment, the particulate dehumidifying agent 41, the particulate adsorbent 42, and the fine powder adsorbent 43 are mixed in a weight ratio of approximately 150:1:1. The proportion of the particulate adsorbent 42 can also be zero. In addition to the above, other additives may be mixed into the chemical 40 as needed. Examples of other additives include fragrances, deodorizers, antifungal agents, antibacterial agents, thickeners, and pigments.

[0013] Examples of the particulate dehumidifying agent 41 include deliquescent dehumidifying agents such as calcium chloride, magnesium chloride, manganese sulfate, citric acid, potassium carbonate, sodium hydroxide, calcium hydroxide, tetraphosphorus hexaoxide, and phosphoric acid, and in this embodiment, particulate calcium chloride is used as the dehumidifying agent. The particle size of the particulate dehumidifying agent 41 used is about 1 to 5 mm.

[0014] Examples of particulate adsorbent 42 include white charcoal such as binchotan, oak white charcoal, and oak white charcoal, black charcoal such as Ikeda charcoal and Sakura charcoal, sawdust charcoal, coconut shell charcoal, open hearth charcoal, dry-distilled charcoal, bamboo charcoal, briquettes, and activated carbon-based physical adsorbents such as activated coconut shell charcoal, and chemical adsorbents such as aluminosilicate, zinc oxide, and titanium oxide. In this embodiment, coconut shell activated carbon was used as the adsorbent. The particle size of particulate adsorbent 42 used was approximately 1 to 5 mm.

[0015] The fine powder adsorbent 43 may be the same activated carbon as the particulate adsorbent 42 described above, but with a smaller particle size, and thus formed into a fine powder, or may be another type of adsorbent formed into a fine powder. The particle size (weight) of the fine powder adsorbent 43 may be such that the fine powder adsorbent 43 can be attached to the inner surface of the container body 20 by static electricity, as described below. In this embodiment, activated carbon with a particle size of 100 mesh or more is used as the fine powder adsorbent 43. If the type of fine powder adsorbent 43 used is changed, the optimal particle size will also change.

[0016] The container 15 has a container body 20 and an antifouling sheet 30 fixed to the container body 20. The container body 20 has a closed internal space R therein. The above-mentioned chemical 40 is accommodated in this internal space R. Furthermore, at least a portion of the container body 20 is formed by a moisture-permeable portion X.

[0017] The moisture-permeable portion X is a part of the wall that constitutes the internal space R of the container body 20. The moisture-permeable portion X is a portion formed from a moisture-permeable sheet including a microporous membrane 24, which will be described later, and has the property of allowing water vapor to pass through but not allowing the aqueous solution stored in the container body 20 to pass through. In this embodiment, the aqueous solution stored in the container body 20 is an aqueous solution produced by deliquescing the dehumidifying agent 41 contained in the chemical 40 due to water vapor.

[0018] The container body 20 is, for example, a so-called standing pouch container formed by bonding together a plurality of sheet members (wall portions) including a moisture-permeable sheet, for example, by heat sealing. The container body 20 is configured so as to be able to be placed on a placing portion 1 such as a desk in an upright position.

[0019] In this embodiment, the container body 20 has, for example, a front wall 21, a rear wall 22, and a bottom wall 23. The container body 20 has an internal space R that can accommodate the drug 40 therein by the front wall 21, the rear wall 22, and the bottom wall 23. The front wall 21 and the rear wall 22 function as vertical walls extending in the direction of gravity. The surface resistivity of the vertical walls 21 and 22 is 10 13Ω or more, and is easily charged with static electricity.

[0020] Furthermore, the container body 20 has a front surface 5 formed by the surface that becomes the outer surface of the front wall portion 21, a rear surface 6 formed by the surface that becomes the outer surface of the rear wall portion 22, and a bottom surface 7 formed by the surface that becomes the outer surface of the bottom wall portion 23. In other words, the outer surface of the container body 20 includes the front surface 5, the rear surface 6, and the bottom surface 7.

[0021] The front wall 21 is transparent and formed from a sheet member that is impermeable to air and the aqueous solution stored in the container 15. The front wall 21 is impermeable to air and water vapor. The front wall 21 is formed, for example, from a plastic sheet made from polyamide, polyethylene, polypropylene, polyester, vinyl chloride, or the like. The front wall 21 is formed, for example, in a rectangular shape. The drug 40 and the stored aqueous solution can be seen through the transparent front wall 21.

[0022] 3, rear wall 22 is formed of a moisture-permeable sheet including microporous membrane 24 that allows the passage of water vapor but restricts the passage of the aqueous solution stored in container body 20. Specifically, this moisture-permeable sheet has microporous membrane 24 and nonwoven fabric 25 fixed to each of both sides of microporous membrane 24 by heat fusion.

[0023] The microporous membrane 24 is, for example, a membrane made of polypropylene having a thickness of about 20 to 200 μm, and is easily charged with static electricity. The microporous membrane 24 is a membrane having a plurality of minute pores. Each of the plurality of pores of the microporous membrane 24 has a size that allows water vapor to pass through but does not allow aqueous solutions to pass through. In this embodiment, for example, the water vapor permeability of the microporous membrane 24 is 2000 g / m 2 24h~8000g / m 2 In other words, the microporous membrane 24 is 1 mm 2Microporous membrane 24 is formed to be permeable to 2000 g to 8000 g of water vapor per day. The pores of microporous membrane 24 have a diameter of, for example, 0.1 μm to 10 μm. Microporous membrane 24 has a plurality of these pores, which allow water vapor to pass through but restrict the passage of aqueous solutions.

[0024] The nonwoven fabric 25 is formed to allow water vapor to pass through its fibers. In this embodiment, the nonwoven fabric 25 is formed from an easily charged material such as polyester, so that static electricity easily builds up on the inner surface 28 of the rear wall 22 on the interior space R side. The nonwoven fabric 25 may also be formed from polyethylene, polypropylene, polyolefin, or the like. The basis weight of the nonwoven fabric 25 is not particularly limited, but is preferably 10 g or more and 200 g or less.

[0025] Furthermore, by fixing the nonwoven fabric 25 to the microporous membrane 24 by heat fusion, the surface of the inner surface 28 has a finely uneven structure due to the nonwoven fabric fibers, making it difficult for the attached fine powder adsorbent 43 to fall off due to vibration, friction, etc. The water vapor permeability of the nonwoven fabric 25 is not particularly limited, but is preferably 8000 g / m 2 24 hours or more, preferably 10,000 g / m 2 - 24 hours or more.

[0026] The rear wall 22 is formed in the same shape as the front wall 21, for example. An edge 22a along one short side of the rear wall 22 configured in this manner is fixed, for example by thermal welding, to an edge 21a along one short side of the front wall 21. An edge 22b along one long side of the rear wall 22 is fixed, for example by thermal welding, to an edge 21b along the long side of the front wall 21. An edge 22c along the long side of the rear wall 22 is fixed, for example by thermal welding, to an edge 21c along the long side of the front wall 21.

[0027] In the rear wall 22 configured in this manner, the portion other than the welded portion serves as a moisture-permeable portion X, which allows air to move between the interior space R of the container body 20 and the outside. In contrast, the welded portion does not face the interior space R, and therefore air does not pass through this portion to enter the interior space R. In other words, the welded peripheral edge 34 of the rear wall 22 is not a portion that surrounds the interior space R, and does not function as a passageway to guide air into the interior space R, and therefore is not a moisture-permeable portion X.

[0028] The bottom wall 23 is formed from a sheet material that is impermeable to the aqueous solution stored in the container body 20 and air. The bottom wall 23 is formed from the same sheet material as the sheet material that forms the front wall 21. The bottom wall 23 is formed in a rectangular shape, for example. The bottom wall 23 is welded to the other longitudinal end of the front wall 21 and the other longitudinal end of the rear wall 22, for example, by heat. The bottom wall 23 is unfolded as shown in FIG. 1 by pulling the front wall 21 and the rear wall 22 away from each other. Note that by folding the bottom wall 23, the container body 20 can be flattened.

[0029] When the medication 40 is contained inside the container body 20, the medication 40 causes the front wall 21 and the rear wall 22 to separate from each other, thereby unfolding the bottom wall 23. When the bottom wall 23 unfolds, the inner surface 26 of the front wall 21 and the inner surface 28 of the rear wall 22 are peeled off, causing static electricity to be charged. Furthermore, when the bottom wall 23 is unfolded, the edge of the front wall 21 along the short side toward the bottom wall 23 and the edge of the rear wall 22 along the short side toward the bottom wall 23 become continuous in an annular shape. In this way, the edge of the front wall 21 along the short side toward the rear wall 22 becomes continuous in an annular shape, allowing the container body 20 to be placed on the placing part 1 with this annular edge as its lower edge.

[0030] As shown in Fig. 2, the stain-resistant sheet 30 has a shape and size sufficient to cover the entire rear surface 6 of the rear wall 22, i.e., the moisture-permeable portion X and the peripheral edge 34. The stain-resistant sheet 30 is made of a material that allows water vapor to pass through and that can prevent external foreign matter from adhering to the rear wall 22. In this embodiment, the stain-resistant sheet 30, as an example, has a paper sheet member 33 and a welding layer 32 formed by applying a welding liquid to one surface of the paper sheet member 33 (the surface facing the rear wall 22). The stain-resistant sheet 30 is fixed to the rear wall 22 with the welding layer 32 facing the rear surface 6 of the rear wall 22.

[0031] The paper sheet member 33 is, for example, an oil-resistant sheet. The paper sheet member 33 is formed to allow air containing water vapor to pass through. Air can pass through the gaps between the fibers that make up the paper sheet member 33. The surface of the paper sheet member 33 is oil-resistant, for example, by applying a non-fluorine-based oil-resistant agent. The oil-resistant treatment may be applied to at least the outer surface of the paper sheet member 33 opposite the welding layer 32, or may be applied to the inner surface on the welding layer 32 side. Alternatively, the paper sheet member 33 may be formed by mixing a fluorine-based oil-resistant agent with a pulp raw material, for example. The water vapor permeability of the paper sheet member 33 in this embodiment is 1000 g / m 2 24 hours or more, preferably 2000g / m 2 - 24 hours or more.

[0032] The welding liquid is a dispersion of particulate heat-sealing agent in a solvent that volatilizes when heated. The solvent is not limited to those that volatilize when heated, and any volatile solvent, such as water, that volatilizes at room temperature, may be used. One example of the welding liquid is an aqueous dispersion of particulate polyolefin, in which case the solvent is water and the heat-sealing agent is particulate polyolefin. For example, Chemipearl (registered trademark) manufactured by Mitsui Chemicals, Inc. is known as a welding liquid in which particulate polyolefin is an aqueous dispersion.

[0033] When fixing the stain-resistant sheet 30 to the rear wall 22, the stain-resistant sheet 30 is placed on the rear surface 6 of the rear wall 22 with the welding layer 32 facing the rear surface 6, and the peripheral edge 34 of the rear wall 22 and the peripheral edge of the stain-resistant sheet 30 are heat-welded to the peripheral edge 34 of the rear wall 22 and the peripheral edge of the stain-resistant sheet 30. That is, in this embodiment, the entire peripheral edge of the stain-resistant sheet 30 is fixed to the rear wall 22 with a gap S between the rear surface 6 of the rear wall 22 and the stain-resistant sheet 30.

[0034] At this time, when the welding liquid of the welding layer 32 is heated to a predetermined temperature and pressurized at a predetermined pressure, the solvent of the welding liquid volatilizes, and the particulate heat-sealing agent dispersed in the solvent at a predetermined ratio melts and collapses. When the melted and collapsed heat-sealing agent cools to a predetermined temperature, it hardens in its collapsed state, bonding the microporous membrane 24 of the rear wall 22 and the paper sheet member 33 of the stain-resistant sheet 30 to each other.

[0035] When the solvent is water, after the welding liquid is applied to one surface of the paper sheet member 33, the water evaporates and dries after a while, leaving particulate heat-sealing agent attached to one surface of the paper sheet member 33. In this case, when the welding layer 32 is heated and pressurized to melt the heat-sealing agent, most of the solvent has already volatilized, and only the heat-sealing agent is heated and melted.

[0036] In either case, when the stain-resistant sheet 30 is fixed to the rear wall 22 by heat welding, the solvent in the welding layer 32 is almost completely removed, and gaps large enough to allow water vapor to pass through are formed between the particles of the heat-sealing agent. As described above, the gaps between the particles of the heat-sealing agent exist in the sealed portion (periphery) where the heat-sealing agent has been heated and melted, and also in the portion other than the sealed portion (the portion facing the gap S).

[0037] For example, if the solvent is water, it begins to volatilize immediately after the welding liquid is applied to one surface of the paper sheet member 33, so most of the solvent will volatilize without heating the welding liquid. In other words, after the particulate heat-sealing agent dispersed in the solvent at a predetermined ratio has volatilized, gaps large enough to allow at least water vapor to pass between the particles of the heat-sealing agent will be formed, regardless of whether heat welding is performed or not.

[0038] In other words, the dispersion ratio of the particulate heat-sealing agent in the solvent of the welding liquid is set to a ratio that will form gaps between the particles of the heat-sealing agent large enough to allow water vapor to pass through when the stain-resistant sheet 30 is heat-sealed to the rear wall 22 using this welding liquid and the solvent of the welding liquid has evaporated. In this embodiment, the water vapor permeability of the stain-resistant sheet 30 in the state where it is heat-sealed to the rear wall 22 is 1000 g / m 2 The dispersion ratio of the particulate heat sealing agent in the solvent of the welding liquid was set so that the time was 24 hours or more.

[0039] When the stain-resistant sheet 30 configured as described above is fixed to the rear surface 6 of the rear wall 22, the welding layer 32 (which is essentially a layer of particulate heat-sealing agent) is permeable to air containing water vapor, and the paper sheet member 33 is also permeable to air containing water vapor, so that air containing water vapor outside the dehumidifying / deodorizing device 10 can easily pass through to the rear wall 22. Furthermore, because the surface of this stain-resistant sheet 30 is formed from the paper sheet member 33, it is possible to prevent the problem of dirt adhering to the rear wall 22 (moisture-permeable portion X) and to prevent the problem of aqueous solution accumulated in the container body 20 leaking to the outside through the rear wall 22. In other words, the dehumidifying device 10 of this embodiment has a high dehumidifying effect, a fast dehumidifying speed, and excellent water retention.

[0040] The stain-resistant sheet 30 may be welded together with the rear wall 22, for example, when the rear wall 22 is welded to the front wall 21 and the bottom wall 23. By doing so, the welded portions of the rear wall 22 and the welded portions of the stain-resistant sheet 30 overlap, thereby reducing the number of welding steps. Alternatively, the stain-resistant sheet 30 may be welded to the rear surface 6 of the rear wall 22 via the gap S, and then this sheet member may be welded together with the front wall 21 and the bottom wall 23. By doing so, there is no need to overlap and weld three sheet members, making the work easier.

[0041] In this embodiment, the stain-resistant sheet 30 has a gap S between it and the rear wall 22 when it is fixed to the rear wall 22. Therefore, even if dirt or the like adheres to the stain-resistant sheet 30, the gap S can more reliably prevent the dirt from adhering to the rear wall 22. Therefore, by providing the gap S, it is possible to more reliably prevent the aqueous solution in the container 15 from leaking to the outside.

[0042] Furthermore, when a pattern is drawn on the surface 35 of the stain-resistant sheet 30 using ink or the like by printing or the like, the gap S can more reliably prevent the ink or the like from adhering to the rear wall portion 22. The pattern may be, for example, at least one of letters, pictures, numbers, and symbols. In other words, the pattern may be anything that is visible to the user. Furthermore, the pattern is not limited to being formed by printing. In another example, the pattern may be drawn by hand.

[0043] Alternatively, the stain-resistant sheet 30 may be heat-sealed to the rear surface 6 of the rear wall 22 of the container body 20 by heat welding one surface of the paper sheet member 33 without leaving a gap S. That is, the entire surface of the stain-resistant sheet 30 may be heat-sealed to the rear wall 22. In this case, the entire surface of the paper sheet member 33 is fixed to the entire rear surface 6 of the rear wall 22 by the particulate heat-sealing agent of the welding layer 32 of the stain-resistant sheet 30. However, as described above, the welding liquid for heat-sealing the paper sheet member 33 to the rear wall 22 is a solvent in which particulate heat-sealing agent is dispersed at a predetermined ratio. Therefore, the welding layer 32, which bonds the two together, has gaps between the particles of the heat-sealing agent large enough to allow water vapor to pass through. Therefore, even if the stain-resistant sheet 30 is fixed to the rear wall 22 without leaving a gap S, water vapor contained in the air outside the dehumidifier / deodorizer 10 can easily pass through toward the rear wall 22.

[0044] Furthermore, when the entire surface of the stain-resistant sheet 30 is fixed to the rear wall 22 as described above, the process of fixing the stain-resistant sheet 30 to the rear wall 22 can be facilitated compared to when the peripheral edges are heat-welded, and the sheet member with the stain-resistant sheet 30 fixed to the rear wall 22 can be handled more easily. In this case, for example, the nonwoven fabric 25 on the rear surface 6 side of the rear wall 22 may be omitted, and the sheet member may be manufactured by heat-welding the stain-resistant sheet 30 to the microporous membrane 24 via a welding liquid, and this sheet member may be used to manufacture the container body 20.

[0045] Furthermore, when the entire surface of the stain-resistant sheet 30 is fixed to the rear wall 22, there is no gap S between them, and therefore no air layer, so the stain-resistant sheet 30 is closer to the internal space R of the container body 20 compared to when there is a gap S. This means that the stain-resistant sheet 30 is also closer to the dehumidifying agent 41 contained in the internal space R, making it easier for water vapor that has permeated the stain-resistant sheet 30 and the rear wall 22 to be adsorbed by the dehumidifying agent 41, thereby improving the dehumidifying effect.

[0046] The function of the above-mentioned dehumidifying and deodorizing device 10 will be described below. When a user holds the dehumidifying and deodorizing device 10, the user's hands come into contact with the front wall 21 of the container body 20 and the stain-resistant sheet 30. At this time, the stain-resistant sheet 30 prevents foreign matter containing surfactant ingredients, such as hand cream, from adhering to the user's hands from adhering to the rear wall 22.

[0047] A portion of the water vapor outside the dehumidifying / deodorizing device 10 passes through the stain-resistant sheet 30 and enters the gap S between the rear wall 22 and the stain-resistant sheet 30. The water vapor that has entered the gap S between the rear wall 22 and the stain-resistant sheet 30 passes through the rear wall 22 and enters the container body 20 (inside the internal space R). The water vapor that has entered the container body 20 deliquesces the dehumidifying agent 41 contained in the chemical 40, becoming an aqueous solution, which accumulates in the container body 20.

[0048] In the dehumidifying and deodorizing device 10 of this embodiment, the entire surface of the rear wall 22 is covered with the stain-resistant sheet 30. Therefore, even if a user touches the dehumidifying and deodorizing device 10 with hands that have foreign matter containing surfactants, such as hand cream, attached to them, the foreign matter can be prevented from adhering to the rear wall 22. Therefore, the surfactants reduce the surface tension, preventing the aqueous solution in the container body 20 from leaking out through the rear wall 22.

[0049] Furthermore, the dehumidifying and deodorizing device 10 of this embodiment accommodates a finely powdered adsorbent 43 in the internal space R of the container body 20. As shown in Figures 2 and 3, a portion of the finely powdered adsorbent 43 adheres by static electricity to the inner surface of the container body 20, i.e., the inner surface 26 opposite the front surface 5 of the front wall 21, and the inner surface 28 opposite the rear surface 6 of the rear wall 22 (the inner surface of the nonwoven fabric 25 inside the rear wall 22).

[0050] Static electricity is generated during the manufacturing, distribution, and use of the dehumidifying / deodorizing device 10 of this embodiment. During the manufacturing of the dehumidifying / deodorizing device 10, it is believed that each sheet member becomes charged when it is pulled out from a material roll (not shown) (peeling electrification). Furthermore, during manufacturing, when the chemical substance 40 is placed in the internal space R of the container body 20, it is believed that static electricity is generated when the bottom wall portion 23 of the container body 20 in a folded state is unfolded to separate the front wall portion 21 and the rear wall portion 22. Furthermore, when the chemical substance 40 is poured into the container 15, the particles of the chemical substance 40 rub against each other and the chemical substance 40 rubs against the inner surfaces 26, 28 of the container 15, generating static electricity (friction electrification and contact electrification).

[0051] Furthermore, when the container 15 is vibrated or shaken during distribution and use of the dehumidifying and deodorizing device 10, it is believed that static electricity is generated as the particles of the chemical 40 rub against each other and the chemical 40 rubs against the inner surfaces 26, 28 of the container 15. The static electricity generated in the internal space R is charged on the inner surface 26 of the front wall 21, the inner surface 28 of the rear wall 22, and the inner surface of the bottom wall 23 of the container body 20, which have high surface resistivity, and the moisture permeable section X and a relatively wide area in its vicinity are charged.

[0052] Furthermore, because the dehumidifying / deodorizing device 10 of this embodiment is a standing pouch that is placed on the placing portion 1 when in use, even if the dehumidifying agent 41 contained in the chemical 40 absorbs water vapor and deliquesces, the resulting aqueous solution will accumulate at the bottom of the internal space R. Therefore, most of the fine powder adsorbent 43 that is statically attached to almost the entire inner surface of the front wall portion 21 and the rear wall portion 22 that extend in the direction of gravity will not sink in the aqueous solution, and the air in the internal space R can be effectively deodorized.

[0053] Furthermore, according to this embodiment, the fine powder adsorbent 43 adheres by static electricity to almost the entire surface of the inner surface 28 of the rear wall portion 22, which is almost entirely the moisture permeable portion X, so that the adsorbent 43 can be effectively brought into contact with the air passing through the moisture permeable portion X, thereby fully demonstrating the deodorizing performance.

[0054] As described above, in order to evaluate the deodorizing performance of the dehumidifying / deodorizing device 10 of this embodiment when a fine powder adsorbent 43 is mixed with the chemical 40 contained in the internal space R of the container body 20, the following deodorizing test was conducted.

[0055] For sample (1) used in the deodorization test, only particulate dehumidifying agent 41 was contained as chemical 40 in the internal space R of the container body 20. The particulate dehumidifying agent 41 in sample (1) was calcium chloride with a particle size of approximately 1 mm to 5 mm, and 170 g of this calcium chloride was contained in the internal space R. For sample (2), 170 g of calcium chloride with the same particle size as sample (1) was mixed with 1 g of particulate adsorbent 42, and this chemical 40 was contained in the internal space R of the container body 20. For sample (2), 170 g of calcium chloride with the same particle size as sample (1) was mixed with 1 g of particulate adsorbent 42, and this chemical 40 was contained in the internal space R of the container body 20. The particulate adsorbent 42 in sample (2) was activated carbon made from coconut shell with a particle size of approximately 1 mm to 5 mm. For sample (3), 170 g of calcium chloride with the same particle size as sample (1) was mixed with 1 g of finely powdered adsorbent 43, and this chemical 40 was contained in the internal space R of the container body 20. The fine powder adsorbent 43 of sample (3) is activated carbon made from coconut shells with a particle size of about 1 μm to 100 μm.

[0056] Each of the samples (1) to (3) was placed in a 10-liter barrier bag, and a predetermined amount of hydrogen sulfide gas was sealed inside. The change in the hydrogen sulfide concentration in the barrier bag over time was measured. The results are shown in Figure 4.

[0057] According to this, it can be seen that the hydrogen sulfide concentration in sample (3) containing chemical 40 mixed with finely powdered activated carbon drops rapidly immediately after the start of the deodorization test, and the hydrogen sulfide concentration reaches zero after about one hour. In contrast, it can be seen that the hydrogen sulfide concentration in sample (1) containing chemical 40 without activated carbon and sample (2) containing chemical 40 mixed with granular activated carbon did not reach zero even about three hours after the start of the deodorization test.

[0058] Furthermore, when each of the samples (1) to (3) was observed after the deodorization test, it was confirmed that the inner surface 26 of the front wall portion 21 and the inner surface 28 of the rear wall portion 22 of the sample (3) were black and sooty in color, and that the fine powder adsorbent 43 was attached to the inner surfaces 26, 28. In other words, it is believed that the fine powder adsorbent 43 was attached to a wide area of ​​the inner surface 26 of the front wall portion 21 and the inner surface 28 of the rear wall portion 22 in the sample (3), which resulted in an improved deodorizing effect compared to the other samples (1) and (2).

[0059] As described above, according to the dehumidifying and deodorizing device 10 of this embodiment, the fine powder adsorbent 43 contained in the chemical 40 adheres to the inner surface due to static electricity that builds up on the inner surface of the container body 20 during manufacture, distribution, and use of the device. This allows the adsorbent 43 to adhere to a relatively wide area of ​​the inner surface that contacts the internal space R of the container body 20, thereby sufficiently improving deodorizing performance.

[0060] Furthermore, according to this embodiment, the fine powder adsorbent 43 adheres to almost the entire surface of the inner surface 26 of the front wall portion 21, which is extended in the direction of gravity, and the inner surface 28 of the rear wall portion 22. Therefore, even if the dehumidifying agent 41 contained in the chemical 40 deliquesces and the aqueous solution accumulates at the bottom of the internal space R, most of the fine powder adsorbent 43 does not sink into the aqueous solution, and the deodorizing effect can be maintained.

[0061] In the present embodiment, only the rear surface 6 of the multiple surfaces of the container body 20 is formed from a sheet member including the microporous membrane 24. However, surfaces of the container body 20 other than the rear surface 6 may be formed from the moisture permeable portion X. As an example, the front wall portion 21 may be formed from a moisture permeable sheet including the microporous membrane 24 that allows water vapor to pass through and further restricts the passage of an aqueous solution stored in the container 15. In this way, when the front wall portion 21 is formed from a moisture permeable sheet including the microporous membrane 24, the air that has passed through the moisture permeable portion X comes into contact with the fine powder adsorbent 43 attached to the inner surface of the front wall portion 21, further enhancing the deodorizing effect.

[0062] Furthermore, in this embodiment, an example has been described in which the moisture-permeable portion X is formed from a sheet member having nonwoven fabric 25 provided on both sides of the microporous membrane 24, but in other examples, the moisture-permeable portion X may be formed from a sheet member that does not have nonwoven fabric 25 on the inner surface of the microporous membrane 24. In this way, even when the moisture-permeable portion X is formed from a sheet member that does not have nonwoven fabric 25 on the inner surface of the microporous membrane 24, the same effect as in this embodiment can be obtained.

[0063] Furthermore, in this embodiment, a case has been described in which finely powdered coconut shell activated carbon is mixed with the chemical 40 contained in the internal space R of the container body 20, but another finely powdered adsorbent 43, for example, binchotan charcoal crushed into a fine powder, may be mixed with the chemical 40 and contained in the internal space R. The finely powdered adsorbent 43 may be any material that can adhere to the inner surface of the container body 20 by static electricity.

[0064] In this embodiment, the stain-resistant sheet 30 is configured by providing a welding layer 32 with a welding liquid applied to one surface (the surface facing the rear wall 22) of the paper sheet member 33, but it is also possible to use a stain-resistant sheet in which a welding sheet is provided on one surface (the surface facing the rear wall 22) of the paper sheet member. In this case, the welding sheet may be formed, for example, from a polyethylene sheet having a large number of holes.
