Description

[Technical field]

[0001] The present invention relates to a dehumidifier, a dedicated container for the dehumidifier, and a dehumidifying tablet that absorb moisture in the air with a deliquescent moisture absorbent to reduce and maintain the humidity in the space, and are used in closets, chests of drawers, shoe cabinets, and other storage spaces. [Background technology]

[0002] Conventionally, the mainstream dehumidifier is a so-called tank type, which is formed so that a tray is interposed at a high-mid portion of a container having an upper opening, and a granular deliquescent moisture absorbent is stored in the upper space, and the deliquescent liquid of the deliquescent moisture absorbent drips from a drip hole in the tray and is stored in the lower space. In order to prevent the deliquescent liquid from spilling out when the tank type dehumidifier is accidentally tipped over, a moisture-permeable film that does not allow liquid to pass through but allows gas to pass through is adhered or welded to the upper opening to seal the opening. In addition, since it is important to ensure a large contact area between the deliquescent moisture absorbent and the air in order to improve the moisture absorption performance of the dehumidifier, a tray is generally shaped with multiple protrusions arranged, and the granular deliquescent moisture absorbent is stored in the upper space thus formed (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2011-78865 A Summary of the Invention [Problem to be solved by the invention]

[0004] As shown in Fig. 4, the tank-type dehumidifier described in Patent Document 1 is configured to include a container body 4 having an upper opening, a tray-like tray 5 disposed in a middle-high portion of the container body 4 to divide the container body 4 into an upper space N and a lower space M, a moisture-permeable but water-impermeable moisture-permeable film 6 that closes the upper opening, and a sealing sheet 7. This tank-type dehumidifier is provided with a lid 8 that protects the moisture-permeable film 6 and the sealing sheet 7 and is detachable from the upper opening of the container body 4. In the tank-type dehumidifier configured in this way, a granular deliquescent moisture absorbent C is stored in the upper space N in the container body 4, and when a consumer (user) uses the dehumidifier, the sealing sheet 7 is peeled off from above the moisture-permeable film 6, allowing moisture in the air to pass through the moisture-permeable film 6 and flow into the container body 4, where it is absorbed by the deliquescent moisture absorbent. When the deliquescent moisture absorbent deliquesces and is completely used up, the accumulated deliquescent liquid is drained away by, for example, peeling off the moisture-permeable film 6 attached to the top opening, and the container is discarded. For this reason, used tank-type dehumidifiers must be replaced with new ones, which is costly and leads to waste of resources. This is not just a problem of cost and waste of resources, but also leads to the trouble of having to purchase and transport large, bulky products, and the problem of needing space to store stock items. As mentioned above, the container is naturally large due to the required specifications of ensuring the contact area between the deliquescent moisture absorbent and the air. In addition to the volume of the upper and lower spaces, the air in the space where the multi-stage protrusions are arranged is transported and stored. Furthermore, this is a more serious problem not only for consumers but also for manufacturers, wholesalers, and retailers. This is because it forces companies to secure large transportation capacity and space for transporting products and warehousing, which imposes significant transportation and storage costs. On the other hand, it has been some time since companies have begun to make efforts toward sustainability, and the trends of companies are constantly attracting attention in terms of the development of sustainable materials and how they can build systems that prevent the waste of resources.

[0005] The present invention is aimed at addressing these problems, and aims to provide a dehumidifier, a container for a dehumidifier, and a dehumidifying tablet that are environmentally friendly, significantly reduce the amount of plastic used, and reduce transportation and storage costs. [Means for solving the problem]

[0006] The present invention solves the above-mentioned problems by providing a dehumidifier that uses a combination of a tablet as a deliquescent moisture absorbent in which a deliquescent substance is pressurized and compressed, and a dedicated container, the dedicated container comprising a deliquescent liquid storage container and a lid, the deliquescent liquid storage container being capable of storing the deliquescent liquid of the tablet, the lid ensuring a robust connection with the deliquescent liquid storage container, having an opening on the upper surface, and the opening being sealed with a moisture-permeable film, the deliquescent liquid storage container being characterized in that the inscribed circle radius of the inner circumference near the upper inlet is larger than the circumscribed circle radius of the outer circumference of the tablet, while the inscribed circle radius of the inner circumference at a position a predetermined height lower than the upper inlet is smaller than the circumscribed circle radius of the outer circumference of the tablet.

[0007] The present invention also solves the above-mentioned problems by providing a dedicated container for a dehumidifier that can be used as a dehumidifier by storing tablets as a deliquescent moisture absorbent in a state in which a deliquescent substance is pressurized and compressed, the dedicated container comprising a deliquescent liquid storage container and a lid, the deliquescent liquid storage container being capable of storing the deliquescent liquid of the tablet, the lid ensuring a robust connection with the deliquescent liquid storage container, having an opening on the upper surface, and the opening being sealed with a moisture-permeable film, the deliquescent liquid storage container being characterized in that the inscribed circle radius of the inner circumference near the upper inlet is larger than the circumscribed circle radius of the outer circumference of the tablet, while the inscribed circle radius of the inner circumference at a position a predetermined height lower than the upper inlet is smaller than the circumscribed circle radius of the outer circumference of the tablet.

[0008] Furthermore, the present invention also solves the above-mentioned problems by providing a cylindrical dehumidifying tablet that can be used as a dehumidifier in combination with a dedicated container in which the inscribed circle radius of the inner circumference at a position a predetermined height lower than the upper inlet is smaller than the inscribed circle radius of the inner circumference near the upper inlet, the dehumidifying tablet being a deliquescent moisture absorbent in a compressed state in which a deliquescent substance is pressurized, the height of the dehumidifying tablet being smaller than the predetermined height set for the dedicated container and twice the height being set larger than the predetermined height of the dedicated container, and the circumscribed circle radius of the outer circumference being smaller than the inscribed circle radius of the inner circumference near the upper inlet of the dedicated container and larger than the inscribed circle radius of the inner circumference at a position a predetermined height lower than the upper inlet. Effect of the Invention

[0009] According to the present invention having the above-mentioned characteristics, it is possible to reuse the container and further to reduce the amount of plastic used in the container itself, thereby making it possible to provide a dehumidifier, a dedicated container for a dehumidifier, and a dehumidifying tablet that can significantly reduce the amount of plastic used and reduce transportation and storage costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, but the drawings are created for the purpose of explanation, and in order to make the explanation easier to understand, some members not necessary for the explanation may not be shown intentionally. In addition, some members may be shown intentionally large or small for the purpose of explanation, and the drawings are not drawn to an exact scale.

[0012] First Embodiment (Overall configuration of the dehumidifier) FIG. 1 is an explanatory diagram showing the overall configuration of a dehumidifier according to a first embodiment of the present invention, in which FIG. 1(a) is a cross-sectional view of a deliquescent liquid storage container with the lid removed and dehumidifying tablets placed on it, FIG. 1(b) is a top view of the deliquescent liquid storage container with the lid removed, FIG. 1(c) is a cross-sectional view of the lid, and FIG. 1(d) is a photograph of dehumidifying tablets contained in an airtight bag.

[0013] The dehumidifier according to the first embodiment of the present invention is a dehumidifier that uses a combination of a dedicated container and a dehumidifying tablet T. As shown in Fig. 1(a) to Fig. 1(c), the dedicated container includes a deliquescent liquid storage container 1 and a lid 2. The deliquescent liquid storage container 1 is configured to be capable of storing the deliquescent liquid of the dehumidifying tablet T in its lower portion. The lid 2 ensures a robust connection with the deliquescent liquid storage container 1 with the dehumidifying tablet T interposed therebetween. Specifically, it is configured as a screw cap or a twist cap.

[0014] From the cross-sectional view of FIG. 1(a), it can be seen that the dehumidifying tablet T is supported by the rib R formed on the inner surface of the deliquescent liquid storage container 1 and is arranged in a state of floating from the bottom surface. That is, the rib R supports the dehumidifying tablet T, so that the dehumidifying tablet T is arranged at a predetermined height position from the inner bottom surface of the deliquescent liquid storage container 1. Naturally, the upper surface of the dehumidifying tablet T is also located at a specific height from the inner bottom surface of the deliquescent liquid storage container 1, and it becomes possible to set the distance between the upper surface of the dehumidifying tablet T and the moisture-permeable film F provided on the lid 2 described later to a constant and close distance. From the top view of FIG. 1(b), it can be seen that the rib R is composed of three parts. From FIG. 1(c), it can be seen that the opening 212 (not shown) provided on the upper surface of the lid 2 is sealed by welding the moisture-permeable film F to form the lid upper surface 21.

[0015] (Configuration of deliquescent liquid storage vessel) A male thread 14 is formed on the outer periphery of the upper part of the main body of the deliquescent liquid storage container 1, which is screwed into the female thread 221 of the lid 2. The thread is preferably a multiple start thread so that it can be opened and closed with a small number of turns, and is configured as a two-start thread or a four-start thread.

[0016] A rib R is formed on the inner surface of the deliquescent liquid storage container 1. The rib R is composed of three parts: a tablet support part 11, a tablet guide part 12, and a tablet drop suppression part 13. In this embodiment, as shown in FIG. 1(b), four ribs R are arranged at 90 degree intervals in the circumferential direction. The radius of the inscribed circle defined by the tip of the tablet support part 11 from the inner circumference toward the center of the deliquescent liquid storage container 1 is set to be smaller than the outer circumference (circumscribed circle) of the dehumidifying tablet T. As a result, the tablet support part 11 fulfills the function of supporting the dehumidifying tablet T, so that the dehumidifying tablet T is placed at a predetermined height position from the inner bottom surface of the deliquescent liquid storage container 1.

[0017] The tablet guide portion 12 is inclined from the inner circumferential surface of the deliquescent liquid storage container 1 toward the center so that the dehumidifying tablet T is placed at the center of the deliquescent liquid storage container 1 even if the dehumidifying tablet T is casually inserted from the inlet of the deliquescent liquid storage container 1. Naturally, the placed dehumidifying tablet T is not likely to come into contact with the inner wall surface of the container, and the deliquescent liquid flows down smoothly. The tablet drop prevention portion 13 is inclined from the tip of the tablet support portion 11 toward the center so that the dehumidifying tablet T does not immediately drop downward even if the deliquescent tablet T progresses and the outer circumference becomes smaller. However, it is not out of the technical idea of ​​the present invention to make the shape linear instead of inclined. A dehumidifier is required to perform at its maximum capacity immediately after being placed in a humid closed space, and a slight decrease in capacity may be acceptable in the latter stages of use of the dehumidifier, and if this is the required specification, the inclination of the tablet drop suppression part 13 is not so required. Note that the rib R is attached to the deliquescent liquid storage container 1 by fusion or the like, but it may be molded integrally with the deliquescent liquid storage container 1.

[0018] (Lid configuration) The lid 2 is generally composed of a lid top surface 21 and a lid side surface 22, and a circular opening 212 (not shown) is provided in the center of the lid top surface 21. On the other hand, the peripheral edge 211 of the lid top surface 21 is set to be one step higher than the lid top surface 21, and the moisture permeable film F is heat-sealed to this peripheral edge 211. In addition, a hanging edge 222 hangs downward from the outer periphery of the opening 212 (not shown). If the size is set so that the opening 212 abuts against the upper surface of the dehumidifying tablet T when the lid 2 is attached to the deliquescent liquid storage container 1, it can be used as a guide for keeping the lid top surface 21 and the dehumidifying tablet T very close to each other at a constant distance. Note that the illustrated one is not set in such a way.

[0019] The dedicated container in the dehumidifier according to the first embodiment is configured such that when the lid 2 is closed, liquid does not pass through but gas passes through the moisture-permeable film F. The moisture-permeable film must be strong enough to withstand repeated use, and a moisture-permeable film having a two-layer structure in which a nonwoven fabric is laminated to a porous film made of stretched polyethylene or polypropylene containing an inorganic filler is preferably used. In order to provide even greater strength, a moisture-permeable film having a three-layer structure in which a nonwoven fabric, a porous film, and a nonwoven fabric are laminated may also be used.

[0020] In general desiccant products, a moisture-proof film is applied over a moisture-permeable film, so the moisture-proof film must be glued to the container. In addition, the moisture-proof film must be peeled off when the desiccant is used, so it must be easy to peel off without damaging the porous film layer. If a moisture-proof film is directly laminated onto a porous film made of stretched polyethylene or polypropylene containing inorganic fillers, it is difficult to easily peel off the porous film layer without damaging it. To solve this problem, a nonwoven fabric is mainly laminated onto the porous film. In this case, the nonwoven fabric is required to complement the strength of the porous film without inhibiting the moisture permeability of the porous film as much as possible. In addition, the nonwoven fabric is required to have heat welding properties to facilitate adhesion to containers and adhesion to the moisture-proof film. For this reason, the fibers of the nonwoven fabric have a sheath-core structure of PE and PET. In the first embodiment, since no moisture-proof film is required, the nonwoven fabric (at least one side of the nonwoven fabric in the case of a three-layer structure) does not need to be heat-sealed, and therefore cheaper PP or PET nonwoven fabric can be used instead of the expensive sheath-core nonwoven fabric. A female screw portion 221 is formed on the inner circumference of the lid side surface 22, which is screwed into the male screw portion 14 formed on the outer circumference of the upper body of the deliquescent liquid storage container 1. The screw is preferably a multiple thread so that it can be opened and closed with a small number of turns, and is configured as a two-thread thread or a four-thread thread. Also, instead of the female screw portion 221, a lug (claw) may be provided on the inner circumference of the lid side surface 22 to form a cap that is wound around the male screw portion 14, a so-called twist cap. The operator feels the torque resistance increasing and finally feels a clicking sensation, so that he can confirm that the lid has been securely closed.

[0021] (Composition of dehumidifying tablets) The dehumidifying tablet T is a deliquescent moisture absorbent in a state in which a deliquescent substance is compressed under pressure, specifically, calcium chloride in tablet form. It is manufactured by filling powdered calcium chloride into the inside of a cylinder of a 50t press (tabletting machine) and extruding a molded product by pressing. The tableted calcium chloride can achieve a density of 1.63g / ml by simply adjusting the pressure, and has sufficient strength for practical use. It is also possible to use magnesium chloride tablets as a substitute for calcium chloride. The dehumidifying tablet T is stored in an airtight transparent bag as shown in FIG. 1(d) during storage. This bag is a transparent bag made of, for example, stretched polypropylene or polyvinylidene chloride, which has water vapor barrier properties so that the deliquescent agent does not deliquesce, but it does not have to be transparent. It may also be laminated, for example, by bonding with polyethylene or the like using nylon film, aluminum foil, or aluminum vapor deposition. Regarding the lamination method, four-sided seal, three-sided seal (palm lamination), standing pouch, blister packaging, etc. can be appropriately adopted. Furthermore, instead of bags, boxes and cans can also be adopted as storage containers as long as they have water vapor barrier properties.

[0022] On the premise that the deliquescent liquid storage container 1 is formed such that the inscribed circle radius of the inner circumference in the vicinity of the upper inlet is larger than the inscribed circle radius of the inner circumference at a position a predetermined height lower than the upper inlet, the dimensions of the dehumidifying tablet T are set as follows. That is, the height of the dehumidifying tablet T is set smaller than a predetermined height, which is the distance from the upper inlet set for the deliquescent liquid storage container 1, and twice the height is set larger than the predetermined height. In addition, the circumscribed circle radius of the outer circumference of the dehumidifying tablet T is set smaller than the inscribed circle radius of the inner circumference in the vicinity of the upper inlet of the deliquescent liquid storage container 1, and larger than the inscribed circle radius of the inner circumference at a position a predetermined height lower than the upper inlet. The dehumidifying tablet T with such dimensions set exhibits an optimized dehumidifying ability. By setting the height dimension, the distance between the moisture permeable film F and the upper surface of the dehumidifying tablet T can be kept constant, and the moisture absorption (moisture absorption speed) can be increased. Regarding this matter, according to an experiment conducted by the present inventors in the preceding application, it has been found that if the distance between the moisture-permeable film F and the upper surface of the dehumidifying tablet T is sufficiently close, a dehumidifying effect comparable to that of a conventional tank-type dehumidifier in which a multi-stage protrusion is arranged on the tray to ensure a large contact area between the deliquescent moisture absorbent and the air can be obtained. The reason for this is considered as follows. When comparing the deliquescent speed of "multiple granules" and "one tablet" for a deliquescent substance of the same weight and concentration without using a moisture-permeable film, the granular form with a larger surface area is superior. However, in a dehumidifier equipped with a moisture-permeable film, the "flow rate of the amount of water vapor drawn into the container through the moisture-permeable film" is determined by the "performance of the moisture-permeable film", the "area of ​​the opening of the lid and container", the "surface area of ​​the deliquescent substance", and the "distance between the deliquescent substance and the moisture-permeable film" due to its structure. In addition, by setting the diameter of the dehumidifying tablet T, a certain gap is provided between the inner surface of the deliquescent liquid storage container 1 and the side surface of the dehumidifying tablet T, allowing the deliquescent liquid to smoothly flow downward, thereby preventing a decrease in hygroscopicity. Furthermore, by setting the height, if two dehumidifying tablets T are accidentally stacked, the lid 2 cannot be closed, so that the mistake can be noticed.

[0023] (How to use a dehumidifier) A method of using the dehumidifier according to the first embodiment of the present invention will be described. (1) Prepare the dehumidifying tablets T stored in a transparent bag and a special container before use. (2) The lid 2 attached to the deliquescent liquid storage container 1 is rotated in the opening direction to remove the lid 2. (3) Open the dehumidifying tablet T. (4) The removed dehumidifying tablets T are placed on the tablet support parts 11 of the ribs R on the inner surface of the deliquescent liquid storage container 1. Since the ribs R are provided with inclined tablet guide parts 12, the dehumidifying tablets T will be naturally placed in the center even if they are inserted carelessly. Naturally, there is no risk of the placed dehumidifying tablets T coming into contact with the inner wall surface of the container. (5) Rotate the lid 2 in the closing direction relative to the deliquescent liquid storage container 1. Finally, when you confirm that the torque resistance increases and you feel a click, the capping is complete. (6) Set up a dehumidifier in the space you want to dehumidify, such as a closet, dresser, or shoe cupboard, and dehumidify the space. (7) When all the tablets T are deliquesced and the dehumidifying performance is reduced, the lid 2 is removed and the deliquescent liquid accumulated in the deliquescent liquid storage container 1 is poured out and discarded. In addition, the inside of the deliquescent liquid storage container 1 is washed as necessary. After step (8), the process returns to step (2) above, and a new dehumidifying tablet T can be used for reuse.

[0024] Second Embodiment (Overall configuration of the dehumidifier) Figure 2 is an explanatory diagram showing the overall configuration of a dehumidifier according to a second embodiment of the present invention, in which Figure 2(a) is a cross-sectional view of a deliquescent liquid storage container with the lid removed and dehumidifying tablets placed on it, Figure 2(b) is a top view of the deliquescent liquid storage container with the lid removed, Figure 2(c) is a cross-sectional view of the lid, and Figure 2(d) is a photograph of dehumidifying tablets contained in an airtight bag.

[0025] The dehumidifier according to the second embodiment of the present invention is a dehumidifier that uses a combination of a dehumidifying tablet and a dedicated container. The dehumidifying tablet T is the same as that used in the first embodiment, and therefore a description thereof will be omitted.

[0026] As shown in Fig. 2(a) to Fig. 2(c), the dedicated container includes a deliquescent liquid storage container 1A and a lid 2A. However, the lid 2A is exactly the same as the lid 2 of the first embodiment. The deliquescent liquid storage container 1A is configured so that the deliquescent liquid of the dehumidifying tablets T can be stored in the lower part thereof. The lid 2A(2) ensures a robust connection with the deliquescent liquid storage container 1A with the dehumidifying tablets T interposed therebetween. Specifically, it is configured as a screw cap or a twist cap.

[0027] From the cross-sectional view of FIG. 2(a), it can be seen that the dehumidifying tablet T is supported by the protrusion P formed on the inner surface of the deliquescent liquid storage container 1 and is arranged in a state of floating from the bottom surface. That is, the protrusion P supports the dehumidifying tablet T, so that the dehumidifying tablet T is arranged at a predetermined height position from the inner bottom surface of the deliquescent liquid storage container 1A. Naturally, the upper surface of the dehumidifying tablet T is also located at a specific height from the inner bottom surface of the deliquescent liquid storage container 1A, and it becomes possible to set the distance between the upper surface of the dehumidifying tablet T and the moisture-permeable film F provided on the lid 2A(2) to a constant and close distance. From the top view of FIG. 2(b), it can be seen that the protrusion P is composed of two parts. From FIG. 2(c), it can be seen that the opening 212 (not shown) provided on the upper surface of the lid 2A(2) is sealed by welding the moisture-permeable film F to form the lid upper surface 21.

[0028] (Configuration of deliquescent liquid storage vessel) A male thread portion 14A is formed on the outer periphery of the upper part of the main body of the deliquescent liquid storage container 1A, which is screwed into the female thread portion 221 of the lid 2A(2). The thread is preferably a multiple start thread so that it can be opened and closed with a small number of turns, and is configured as a two-start thread or a four-start thread.

[0029] A protrusion P is formed on the inner surface of the deliquescent liquid storage container 1A. The protrusion P is composed of two parts, a tablet support part 11A and a tablet guide part 12A, and in this embodiment, as shown in FIG. 2(b), four protrusions P are arranged at 90 degree intervals in the circumferential direction. The radius of the inscribed circle defined by the tip of the tablet support part 11A from the inner circumference toward the center of the deliquescent liquid storage container 1A is set to be smaller than the outer circumference (circumscribed circle) of the dehumidifying tablet T. As a result, the tablet support part 11A fulfills the function of supporting the dehumidifying tablet T, so that the dehumidifying tablet T is placed at a predetermined height position from the inner bottom surface of the deliquescent liquid storage container 1.

[0030] The tablet guide portion 12A has an inclined shape that gradually approaches the center from the inner peripheral surface of the deliquescent liquid storage container 1 so that the dehumidifying tablet T is placed at the center position of the deliquescent liquid storage container 1A even if the dehumidifying tablet T is casually thrown into the inlet of the deliquescent liquid storage container 1A. Note that the protrusion P is attached to the deliquescent liquid storage container 1 by fusion or the like, but may be molded integrally with the deliquescent liquid storage container 1.

[0031] As shown in FIG. 2(a), the deliquescent liquid storage container 1A in which the protrusions P are formed instead of the ribs R does not have a tablet drop prevention part for preventing the dehumidifying tablets T from dropping downward. However, since the dehumidifier is required to exert its maximum capacity immediately after being placed in a humid closed space, a slight decrease in capacity may be acceptable in the latter stage of use of the dehumidifier. Even in this embodiment, the intended object of providing a dehumidifier that is environmentally friendly and can reduce transportation and storage costs is achieved. In addition, the expressions "rib R" and "protrusions P" are used to explain the embodiment, but both of these belong to "rib" in the broad sense. In other words, the term "rib" used in the claims also includes "protrusions P".

[0032] <Third embodiment> FIG. 3 is an explanatory diagram showing a third embodiment of the present invention. The dehumidifier of the third embodiment is composed of a dedicated container consisting of a deliquescent liquid storage container 1B and a lid 2B, and dehumidifying tablets TB1 or TB2. The dehumidifier according to the third embodiment of the present invention is the same as the first and second embodiments in that a dedicated container and a dehumidifying tablet are used in combination, but is different from the first and second embodiments in that it does not have a rib or the like that functions to support the dehumidifying tablet T. Instead, the deliquescent liquid storage container 1B in the third embodiment has a shape in which the upper part of the inside of the container opening is narrowed into a truncated cone shape. As a result, the deliquescent liquid storage container 1B is configured so that the inscribed circle radius of the inner circumference at a position lower than the upper inlet by a predetermined height is smaller than the inscribed circle radius of the inner circumference near the upper inlet, and the tablet can be supported at a height position where the inscribed circle radius is equal to the circumscribed circle radius of the dehumidifying tablet TB1 or the dehumidifying tablet TB2.

[0033] On the other hand, if the tablet shape is simply cylindrical, the deliquescent liquid will not flow downward, so the shape is devised. That is, the dehumidifying tablet TB1 is doughnut-shaped with a hole in the center, and the dehumidifying tablet TB2 has a curved side. This allows a gap to be provided between the tablet and the deliquescent liquid storage container 1B, allowing the deliquescent liquid to flow downward smoothly. In addition, by making the tablet shape polygonal, a gap can be provided between the tablet and the inner side of the deliquescent liquid storage container 1B, allowing the deliquescent liquid to flow downward smoothly.

[0034] The dehumidifier according to the embodiment of the present invention has been described in detail with reference to the drawings, and its structure has been described above, but the specific configuration is not limited to these embodiments, and even if the design is changed within the scope of the present invention, it is included in the present invention. For example, the circular shape that is the common shape of the deliquescent liquid storage container and the lid may be other shapes such as a rectangular shape as long as the relationship between the inscribed circle radius of the container inner circumference and the circumscribed circle radius of the tablet outer circumference is maintained, in other words, as long as the dehumidifying tablet can be supported at a predetermined height. In addition, the ribs R and protrusions P that are arranged four at 90° intervals in the circumferential direction may be arranged three at 120° intervals. In addition, the relationship between the height of the dedicated container and the dehumidifying tablets is set so that the lid will not close if two dehumidifying tablets are accidentally stacked on top of each other, on the premise that the height of the placed dehumidifying tablets does not protrude from the dedicated container, but it is also possible to configure the tablets to be placed appropriately in the dedicated container by providing a thickness to the lid while allowing the height of the placed dehumidifying tablets to protrude from the dedicated container. However, it goes without saying that it is important to set the dimensions so that the lid will not close if two dehumidifying tablets are accidentally stacked on top of each other.
