DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0039] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0040] First Embodiment A hydrogen generating device 1 in a first embodiment of the present invention will be described with reference to Fig. 1. The hydrogen generating device 1 in this embodiment includes a container portion 10, a hydrogen generating agent packaging body 20, and a movement restricting portion 30. In Figs. 1(A) and (B), the hydrogen generating device 1 is packaged in an external packaging body 40. In this specification, the hydrogen generating device 1 packaged in the external packaging body 40 will also be referred to as the hydrogen generating device 1 as appropriate.

[0041] <Container part> As shown in Figs. 1(A) and (B), the container 10 is formed in a bottomed cylindrical shape with an opening 11 provided on one side in the depth direction of the container 10 and the other side in the depth direction of the container 10 being closed. The container 10 has an internal space 10A inside that communicates with the outside through the opening 11. Specifically, the container 10 has, for example, a truncated cone shape, and has a bottom wall 12 (bottom part) and a peripheral wall 14. The bottom wall 12 (bottom part) is provided on the bottom side where the diameter of the truncated cone shape is small. The container 10 has an opening 11 on the bottom side where the diameter of the truncated cone shape is large.

[0042] The peripheral wall 14 is an annular wall that starts from the outer edge of the bottom wall 12 and extends in a vertical direction having a component in the axial direction (hereinafter referred to as the container axial direction) A of the container portion 10. The container axial direction A is parallel to the depth direction of the container portion 10. The peripheral wall 14 is formed in a tapered shape that is inclined so as to expand radially outward as it advances along the container axial direction A toward the opening 11. Therefore, the peripheral wall 14 is inclined with respect to the container axial direction A. The peripheral wall 14 also has a peripheral wall piece 14E (corresponding to the base wall 16 in the eighth embodiment described later) that starts from the outer edge of the bottom wall 12 and extends on the opposite side to the opening 11.

[0043] Examples of the material of the container 10 include paper, polyethylene (PE), polystyrene (PS), polypropylene (PP), and polyethylene terephthalate (PET). That is, the container 10 is assumed to be, for example, a paper cup or a plastic cup. Also, the container 10 may be partially or entirely made of a transparent material (see the window in the thirteenth embodiment described later).

[0044] In addition, it is preferable that the inner bottom surface 12A of the bottom wall 12 of the container part 10 is provided with a moisture blocking layer 13 made of a material that blocks moisture or does not allow moisture to pass through. An example of a moisture blocking material is aluminum, but it is not limited to this and other materials may be used. The moisture blocking layer 13 is provided by evaporating aluminum onto the inner bottom surface 12A of the container part 10. When the moisture blocking layer 13 is provided, the surface of the moisture blocking layer 13 corresponds to the inner bottom surface 12A.

[0045] <Hydrogen generating agent packaging> The hydrogen generating agent package 20 will be described with reference to FIG. 2. As shown in FIG. 2(B), the hydrogen generating agent package 20 is formed in a bag shape and contains a hydrogen generating agent 21. The hydrogen generating agent package 20 is independent of the container part 10 and can be easily inserted into and removed from the container part 10. That is, when the hydrogen generating agent package 20 is contained inside the container part 10, the hydrogen generating agent 21 is contained inside the container part 10. The hydrogen generating agent 21 generates hydrogen in response to a liquid such as water. The material of the hydrogen generating agent 21 is, for example, a mixture of aluminum (Al) and calcium oxide (CaO), but is not limited thereto, and may be any other material that generates hydrogen in response to a liquid. An example of calcium oxide (CaO) is powdered quicklime. Aluminum (Al) is used, for example, in a powder form. That is, both aluminum (Al) and calcium oxide (CaO) are preferably powdered. The hydrogen generating agent 21 configured as above reacts with water to generate hydrogen. The liquid is not limited to water. The liquid includes all kinds of liquids that react with the hydrogen generating agent 21 to generate hydrogen.

[0046] 2(A) and (B), the hydrogen generating agent 21 is housed in a bag body 23 having a bag mouth 22, for example. The bag body 23 has a lid piece 24 that closes the bag mouth 22. The lid piece 24 is a portion that extends from the bag body main body 25 in the length direction of the bag body 23 starting from the bag mouth 22. The bag body 25 may be provided with a gusset 25A so that the thickness of the bag body 25 increases. The hydrogen generating agent 21 is packed inside the bag body 25 through the bag mouth 22. When a predetermined amount of the hydrogen generating agent 21 is packed inside the bag body 25, the lid piece 24 is placed over the bag mouth 22 to close the bag mouth 22.

[0047] In addition to the hydrogen generating agent 21, the bag body 23 may contain an aromatic agent containing an aroma component. Examples of aromatic agents include those containing coffee bean components, those containing vanilla components, and those containing fruit aroma components such as strawberry, but are not limited to these, and include all other aromatic agents. In this way, the hydrogen generating device 1 in this embodiment can generate not only hydrogen but also aroma components. As a result, the user of the hydrogen generating device 1 can inhale hydrogen without getting bored. However, the aromatic agent must not lose its aroma when liquid is poured into it.

[0048] The aromatic agent may not be contained in the bag 23, but may be included in the liquid for hydrogen generation that is poured later into the hydrogen generating agent 21. The aromatic agent may also be added to the liquid later. Even in this case, the hydrogen generating device 1 can generate not only hydrogen but also a fragrance component in the same manner as described above.

[0049] The bag 23 (bag body 25) is provided with a plurality of fine ventilation holes. The plurality of fine ventilation holes are preferably of a size that allows the liquid used in hydrogen generation and the gas containing hydrogen generated from the hydrogen generating agent 21 to pass through, but does not allow the hydrogen generating agent 21 and the aromatic agent themselves to pass through. The bag 23 may be a braided body made of fibers. In this case, the mesh of the braided body corresponds to the fine ventilation holes. The bag 23 (bag body 25) may also be formed of a nonwoven fabric.

[0050] <Movement restriction section> The movement limiting part 30 will be described with reference to Figs. 3 to 5. The movement limiting part 30 limits the movement range of the hydrogen generating agent package 20 inside the container part 10. In this embodiment, the hydrogen generating agent package 20 is placed on the inner bottom surface 12A of the container part 10 as shown in Fig. 3(A). Then, the movement limiting part 30 is composed of a package fixing part 31 that fixes the hydrogen generating agent package 20 to the inner bottom surface 12A of the container part 10 so that the hydrogen generating agent package 20 does not rise to the water surface when the liquid 100 is poured into the container part 10 as shown in Fig. 3(B). If the movement range of the hydrogen generating agent package 20 is within a range where the entire hydrogen generating agent package 20 can come into contact with the liquid, the entire hydrogen generating agent package 20 is always cooled by the liquid. Therefore, even if the hydrogen generating agent 21 generates heat when reacting with the liquid, the temperature of the container part 10 can be reduced. As a result, the user of the hydrogen generating device 1 does not feel hot when holding the container part 10.

[0051] In this embodiment, the hydrogen generating agent package 20 has a belt-like region 26 and a main region 27, as shown in FIG. 3(C). The belt-like region 26 extends along the side 20C of the hydrogen generating agent package 20 on the bag mouth 22 side in the vicinity of the side 20C. In this embodiment, the side 20C on the bag mouth 22 side extends in a substantially straight line. In this embodiment, the belt-like region 26 extends only along a part of the side 20C, but is not limited thereto, and may extend along the entire side 20C. In this embodiment, the width of the belt-like region 26 in the width direction B is, for example, preferably 1 / 3 or less of the total length in the length direction C of the hydrogen generating agent package 20 parallel to the width direction B, more preferably 1 / 4 or less of the total length, and even more preferably 1 / 5 or less of the total length. The main region 27 is a main part of the hydrogen generating agent package 20, and is continuous with the belt-like region 26 on the longitudinal side of the belt-like region 26.

[0052] As shown in FIG. 3(B), the packaging body fixing part 31 fixes the belt-like surface 26A on one side of the belt-like region 26 to the inside bottom surface 12A of the container part 10. The packaging body fixing part 31 may be fixed, for example, by glue, double-sided tape, or heat fusion. This allows the main region 27 to move around the boundary between the belt-like region 26 and the main region 27 as an axis. That is, when the liquid 100 is poured into the container part 10, the main region 27 can rise up so as to sway (swirl) around the boundary with the belt-like region 26 as an axis. At this time, the main region 27 can take a position inclined with respect to the inside bottom surface 12A as shown in FIG. 3(B). In this state, the liquid 100 contacts the main region 27 from both the front surface 27A side and the back surface 27B side. Therefore, the liquid 100 contacts the hydrogen generating agent 21 efficiently, and hydrogen is generated efficiently.

[0053] As shown in Fig. 4(A), the packaging body fixing part 31 may fix the hydrogen generating agent package 20 to the inner bottom surface 12A of the container part 10 so that the hydrogen generating agent package 20 cannot move even if the liquid 100 is poured into the container part 10. In this case, as shown in Fig. 4(B), the packaging body fixing part 31 may fix a region R that spreads from the central region of the hydrogen generating agent package 20 toward the outer edge of the hydrogen generating agent package 20 to the inner bottom surface 12A of the container part 10. As shown in Fig. 4(B), the region R may be substantially the entire region of the hydrogen generating agent package 20.

[0054] 4(C), the entire region of the hydrogen generating agent package 20 may be divided equally into four, and a portion of each of the four divided regions and a portion of the central region of the hydrogen generating agent package 20 may be fixed to the inner bottom surface 12A of the container portion 10 by the package fixing portion 31. The divided regions are not limited to being divided into four, and may be divided into any other number of regions. Also, a portion of the central region may not be fixed by the package fixing portion 31.

[0055] <Modifications of the packaging body fixing part> 5(A) to (F), modified examples of the packaging body fixing part 31 will be described. As shown in Fig. 5(A), the packaging body fixing part 31 may be configured to press the band-shaped region 26 of the hydrogen generating agent packaging 20 against the inner bottom surface 12A of the container part 10. In this case, the packaging body fixing part 31 has, for example, a base part 390 fixed to the inner bottom surface 12A and a pressing part 391.

[0056] The base 390 is fixed to the inner bottom surface 12A of the container 10. The pressing portion 391 extends in a strip shape from one end of the base 390. As shown in FIG. 5(C), in an initial state in which no external force is applied, the pressing portion 391 abuts against the inner bottom surface 12A or is in the vicinity of the inner bottom surface 12A and assumes a posture approximately parallel to the inner bottom surface 12A of the container 10. In addition, as shown in FIG. 5(B), the pressing portion 391 can rotate in a direction approaching or receding from the inner bottom surface 12A of the container 10, with a boundary line 393 with the base 390 as an axis. Even if the pressing portion 391 is rotated in a direction receding from the inner bottom surface 12A of the container 10, it operates to return to its initial state due to the elastic force at the boundary portion with the base 390. 5(A), the pressing portion 391 is preferably provided with a hole 392 penetrating therethrough in the container axial direction A. At least one hole 392 needs to be provided.

[0057] 5(D), the packaging body fixing part 31 may have, for example, two base parts 390 fixed to the inner bottom surface 12A and a pressing part 391. The two base parts 390 are connected to both ends of the pressing part 391.

[0058] Even in the above cases, the band-shaped region 26 of the hydrogen generating agent package 20 is fixed to the inner bottom surface 12A of the container portion 10. The main region 27 of the hydrogen generating agent package 20 is capable of pivoting about the boundary with the band-shaped region 26 of the hydrogen generating agent package 20 as an axis.

[0059] As shown in FIG. 5(E), the packaging body fixing part 31 may be configured to press the band-like region 26 and the main region 27 of the hydrogen generating agent package 20 against the inner bottom surface 12A of the container part 10. The packaging body fixing part 31 may be configured similar to that described above with reference to FIGS. 5(B) to (D). Also, as shown in FIG. 5(F), the packaging body fixing part 31 may be configured to press the four corners of the hydrogen generating agent package 20 against the inner bottom surface 12A of the container part 10. This packaging body fixing part 31 is similar to that described above with reference to FIGS. 5(B) to (D), except that the length of the pressing part 391 is shortened.

[0060] <External packaging> The external packaging body 40 will be described with reference to Fig. 1. The external packaging body 40 encases the hydrogen generating agent packaging body 20, the movement restriction part 30 and the container part 10 so that dust and the like do not adhere to the inside and outside of the container part 10. In other words, the external packaging body 40 encases the entire hydrogen generating device 1. In this embodiment, the external packaging body 40 is composed of, for example, a transparent or colored film. Examples of the material of the transparent or colored film include, for example, polyethylene, polypropylene, polyamide, polyethylene terephthalate, etc., but are not limited thereto and other materials may be used.

[0061] 1(A) and 1(B), the outer packaging body 40 is packaged so as to be in close contact with the outer peripheral surface 14A of the peripheral wall 14 of the container portion 10, the outer bottom surface 12B of the bottom wall 12, the inner peripheral surface 14B of the container portion 10, the inner bottom surface 12A of the bottom wall 12, and the hydrogen generating agent packaging 20. In this embodiment, since the movement limiting portion 30 is located between the inner bottom surface 12A of the bottom wall 12 and the hydrogen generating agent packaging 20, the outer packaging body 40 does not come into close contact with the movement limiting portion 30. However, in other embodiments described later, the outer packaging body 40 may come into close contact with the movement limiting portion 30.

[0062] 1(B), the outer packaging body 40 is preferably provided with a moisture blocking layer 41 made of a moisture blocking material in a portion facing the hydrogen generating agent packaging 20 in the container axial direction A. If the moisture blocking layer 41 is provided, the hydrogen generating agent packaging 20 can be protected from moisture.

[0063] Second Embodiment The hydrogen generating device 1 in the second embodiment of the present invention will be described with reference to Fig. 6. The hydrogen generating device 1 in this embodiment has the same container portion 10, hydrogen generating agent packaging body 20, and outer packaging body 40 as the hydrogen generating device 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generating device 1 in this embodiment differs from the hydrogen generating device 1 in the first embodiment of the present invention in the configuration of the movement restriction portion 30.

[0064] 6(A) and (B), the movement limiting part 30 in this embodiment has a string part 32 and a string-side fixing part 33. The string part 32 is a string-shaped part, and one end is connected to the hydrogen generating agent packaging 20. Examples of the string part 32 include, but are not limited to, a fiber thread or a resin thread, and the like, and the string part 32 may be made of another material.

[0065] The string-side fixing part 33 fixes the string part 32 inside the container part. In this embodiment, the string-side fixing part 33 has an intermediate member 33A and an intermediate member-side fixing part 33B. The intermediate member 33A is, for example, a sheet-like member. The other end of the string part 32 is connected to the intermediate member 33A. The intermediate member-side fixing part 33B fixes the intermediate member 33A to the inner bottom surface 12A of the container part 10. The intermediate member-side fixing part 33B may be fixed by, for example, glue, double-sided tape, or heat fusion.

[0066] That is, the movement limiting part 30 in this embodiment allows the hydrogen generating agent package 20 to move inside the container part 10 according to the trajectory of one end of the string part 32 when the connection part between the other end of the string part 32 and the intermediate member 33A is used as a fulcrum, but limits other movements. Therefore, in the case of the movement limiting part 30 in this embodiment, when the liquid 100 is poured into the container part 10, the hydrogen generating agent package 20 is limited to a movement range according to the trajectory of the other end of the string part 32, as shown in Fig. 6(B).

[0067] 6(C) and (D), two string parts 32 may be provided. In this case, for example, one string part 32 is connected to the vicinity of the bag mouth 22 of the hydrogen generating agent package 20, and the other end of the other string part 32 is connected to the vicinity of the bag bottom 28 of the hydrogen generating agent package 20. At this time, one string part 32 is fixed to the inner bottom surface 12A of the container part 10 by an intermediate member side fixing part 33B (for example, glue, double-sided tape, etc.) through an intermediate member 33A. The other string part 32 is directly fixed to the inner bottom surface 12A of the container part 10 by the string side fixing part 33.

[0068] The movement limiting part 30 allows movement of the hydrogen generating agent package 20 inside the container part 10 according to the trajectory of one end of one of the string parts 32 when the connection part between one end of the one string part 32 and the intermediate member 33A is used as a fulcrum, and according to the trajectory of the other end of the string part 32 when the connection part between one end of the other string part 32 and the inner bottom surface 12A is used as a fulcrum, but restricts other movements. Therefore, in the case of the movement limiting part 30, when the liquid 100 is poured into the container part 10, the hydrogen generating agent package 20 is restricted to a movement range according to the trajectories of the other ends of the two string parts 32 as shown in FIG. 6(D).

[0069] <Third embodiment> The hydrogen generating device 1 in the third embodiment of the present invention will be described with reference to Fig. 7. The hydrogen generating device 1 in this embodiment has the same container portion 10, hydrogen generating agent packaging body 20, and outer packaging body 40 as the hydrogen generating device 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generating device 1 in this embodiment differs from the hydrogen generating device 1 in the first and second embodiments of the present invention in the configuration of the movement restriction portion 30.

[0070] 7(A) and (B), the movement restriction section 30 in this embodiment is configured by a storage chamber 34 provided inside the container section 10. The storage chamber 34 has an internal storage space 34A capable of storing the hydrogen generating agent package 20. The storage chamber 34 is configured by a partition wall 35 and a storage chamber component part 10B of the container section 10 that is located below the partition wall 35 in the container axial direction A. The storage chamber component part 10B is configured by the bottom wall 12 of the container section 10 and a peripheral wall piece 14D of the container section 10 that is located below the partition wall 35 in the container axial direction A.

[0071] The partition wall 35 is, for example, disk-shaped as shown in Fig. 7(A). The partition wall 35 divides the internal space 10A of the container part 10 in the container axial direction A as shown in Fig. 7(B). The partition wall 35 is preferably provided at least below the central part of the container part 10 in the container axial direction A, but is not limited thereto, and may be provided above the central part of the container part 10 in the container axial direction A. In this embodiment, the partition wall side facing surface 35C of the partition wall 35 facing the internal bottom surface 12A of the container part 10 is parallel to the internal bottom surface 12A, but is not limited thereto, and may not be parallel.

[0072] A moisture blocking layer 36 made of a moisture blocking material is preferably provided on the partition wall side opposing surface 35C. This is to block moisture from reaching the hydrogen generating agent package 20 accommodated in the accommodation chamber 34.

[0073] Further, a vent hole (which may be referred to as a storage chamber side vent hole: the same applies below) 35A penetrating in the container axial direction A is provided in the central portion of the partition wall 35. Hydrogen generated from the hydrogen generating agent package 20 passes through the vent hole 35A and rises toward the opening 11. Furthermore, at least one vent hole (which may be referred to as a storage chamber side vent hole: the same applies below) 35B penetrating the partition wall 35 in the container axial direction A may be provided around the vent hole 35A. This is to smoothly guide hydrogen generated from the hydrogen generating agent package 20 to the opening 11. In this embodiment, eight vent holes 35B are provided. The storage space 34A of the storage chamber 34 and the internal space 10A of the container part 10 communicate with each other through the vent holes 35A and 35B.

[0074] According to the hydrogen generating device 1 in this embodiment, when the liquid 100 is poured into the container part 10, the hydrogen generating agent package 20 becomes movable within the range of the storage space 34A of the storage chamber 34.

[0075] <First Variation of Containment Chamber> A first modified example of the storage chamber 34 will be described with reference to Figures 8(A) and (B). As shown in Figure 8(A), the first modified example of the storage chamber 34 is configured by a storage chamber component 340 and a bottom wall 12. As shown in Figures 8(A) and (B), the storage chamber component 340 has a bottomed cylindrical shape. Specifically, the storage chamber component 340 has a partition wall 341 and a peripheral wall 342.

[0076] When the storage chamber component 340 is installed on the inner bottom surface 12A of the container part 10, the partition wall 341 becomes similar to the partition wall 35 described above, and therefore a description thereof will be omitted. The peripheral wall 342 is inclined from the outer edge of the partition wall 341 as it approaches the central axis of the storage chamber component 340 as it proceeds downward in the container axial direction A, and has a cylindrical shape resembling a truncated cone. Note that the above-described shape of the peripheral wall 342 is made to match the shape of the inner side of the container part 10, and if the shape of the inner side of the container part 10 is a shape other than a truncated cone, it is preferable that the peripheral wall 342 have a shape corresponding to that shape.

[0077] When the storage chamber component 340 is placed on the inside bottom surface 12A of the container 10, the storage chamber component 340 and the bottom wall 12 form a storage chamber 34. In order to prevent the storage chamber component 340 from floating up when the liquid 100 is poured into the container 10, the storage chamber component 340 is preferably shaped and sized to fit into the container 10 near the inside bottom surface 12A of the container 10. The storage chamber component 340 may be in a state of contacting and fixed to the inside bottom surface 12A of the container 10 or the inner peripheral surface 14B of the container 10. In this case, the bottom surface 342A of the peripheral wall 342 may be fixed to the inside bottom surface 12A of the container 10, or the outer peripheral surface 342B of the peripheral wall 342 may be fixed to the inner peripheral surface 14B of the container 10. The storage chamber component 340 may be configured to have a weight that prevents it from floating up in the liquid.

[0078] <Second Variation of Containment Chamber> A second modified example of the storage chamber 34 will be described with reference to Figs. 8(C) and (D). As shown in Fig. 8(C), the second modified example of the storage chamber 34 is constituted by a storage chamber component 343. As shown in Figs. 8(C) and (D), the storage chamber component 343 has a hollow cylindrical shape. Specifically, the storage chamber component 343 has a ceiling wall 344, a peripheral wall 345, and a bottom wall 346. The ceiling wall 344 corresponds to the ceiling portion of the storage chamber component 343. When the storage chamber component 343 is installed on the inner bottom surface 12A of the container 10, the ceiling wall 344 becomes substantially the same as the partition wall 35 described above, and therefore a description thereof will be omitted.

[0079] The bottom wall 346 corresponds to a bottom portion of the storage chamber forming member 343. When the storage chamber forming member 343 is placed on the inner bottom surface 12A of the container portion 10, the bottom wall 346 abuts against the inner bottom surface 12A.

[0080] The peripheral wall 345 extends downward in the container axial direction A from the outer edge of the ceiling wall 344 to the outer edge of the bottom wall 346. The peripheral wall 345 is inclined so as to approach the central axis of the storage chamber constituent member 340 as it progresses downward in the container axial direction A, and has a cylindrical shape resembling a truncated cone. Note that the above-described shape of the peripheral wall 345 is made to match the shape of the interior side of the container part 10, and if the shape of the interior side of the container part 10 is a shape other than a truncated cone, it is preferable that the peripheral wall 345 have a shape corresponding to that shape.

[0081] Furthermore, the peripheral wall 345 may be provided with an insertion opening 347 for inserting the hydrogen generating agent packaging 20 into the storage space 34A. When the storage chamber constituent member 343 is placed inside the container part 10, the insertion opening 347 is preferably configured to be blocked by the inner peripheral surface 14B of the container part 10. Even if the insertion opening 347 is configured not to be blocked by the inner peripheral surface 14B of the container part 10, the distance between the insertion opening 347 and the inner peripheral surface 14B is small compared to the size of the hydrogen generating agent packaging 20, so that the hydrogen generating agent packaging 20 will not come out of the storage chamber constituent member 343 through the insertion opening 347.

[0082] When the storage chamber component 343 is placed on the inner bottom surface 12A of the container 10, the storage chamber component 343 forms the storage chamber 34. Note that in order to prevent the storage chamber component 343 from floating up when the liquid 100 is poured into the container 10, the storage chamber component 343 may be configured similarly to the storage chamber component member 340 in this respect.

[0083] <Fourth embodiment> The hydrogen generating device 1 in the fourth embodiment of the present invention will be described with reference to Fig. 9. The hydrogen generating device 1 in this embodiment has the same container portion 10, hydrogen generating agent packaging body 20, and outer packaging body 40 as the hydrogen generating device 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generating device 1 in this embodiment differs from the hydrogen generating device 1 in the other embodiments in the configuration of the movement restriction portion 30.

[0084] The movement limiting section 30 in this embodiment is configured by a pressing member 37. In this embodiment, the pressing member 37 has the same shape as the container section 10 as shown in Figs. 9(A) and (B), and is sized so as to be insertable into the container section 10. The pressing member 37 presses the hydrogen generating agent package 20 placed on the inner bottom surface 12A from above in the container axial direction A. As shown in Fig. 9(A), the pressing member 37 has, for example, a pressing side bottom wall 370 and a pressing side peripheral wall 371.

[0085] 9(B), the pressing-side bottom wall 370 is a portion that comes into contact with the hydrogen generating agent package 20 placed on the inner bottom surface 12A. The pressing-side peripheral wall 371 is a tapered cylindrical (annular) wall that starts from the outer edge of the pressing-side bottom wall 370 and inclines away from the central axis of the pressing member 37 as it progresses upward in the container axial direction A, and has a truncated conical cylindrical shape.

[0086] In addition, a detachable attachment mechanism 372 is preferably provided between the outer periphery of the pressing-side peripheral wall 371 and the inner periphery of the peripheral wall 14 of the container part 10. The attachment mechanism 372 is composed of, for example, an annular rib 371A that goes around the outer periphery of the pressing-side peripheral wall 371, and a fitting groove 14C that is provided on the inner periphery of the peripheral wall 14 at a position proximal to the opening 11 of the container part 10.

[0087] The rib 371A is configured with a convex portion that protrudes radially outward from the outer side of the pressing-side peripheral wall 371. The rib 371A is annular and goes around the outer periphery of the pressing-side peripheral wall 371. The fitting groove 14C is configured with a concave portion that recesses radially outward from the inner periphery of the peripheral wall 14. The shape of the concave portion corresponds to the shape of the convex portion of the rib 371A.

[0088] When the pressing side peripheral wall 371 is inserted into the container 10, the rib 371A fits into the fitting groove 14C due to elastic deformation. When the pressing side peripheral wall 371 is pulled outward, the rib 371A comes out of the fitting groove 14C due to elastic deformation.

[0089] <Modification of the pressing side peripheral wall> 9(C) and (D), a description will be given of a band-shaped wall 374 which is a modified example of the pressing-side peripheral wall 371. The pressing-side peripheral wall 371 may be replaced with the band-shaped wall 374. Unlike the above, the band-shaped wall 374 is not cylindrical (annular) but band-shaped.

[0090] The attachment mechanism 372 is composed of a hook portion 375 and the peripheral wall 14 in the vicinity of the opening 11 of the container portion 10. The hook portion 375 is provided on the upper end of the belt-shaped wall 374. The hook portion 375 is a portion shaped so as to be hooked onto the peripheral wall 14. The hook portion 375 is formed, for example, in a U-shape.

[0091] In the first to fourth embodiments, the hydrogen generating agent package 20 is placed on the inner bottom surface 12A of the container 10, but the present invention is not limited thereto. The hydrogen generating agent package 20 may be placed in contact with the inner circumferential surface 14B of the container 10. However, when a large amount of hydrogen generating devices 1 are transported by a transporter, it is assumed that a plurality of hydrogen generating devices 1 are stacked so that the container 10 is inserted into the inner space 10A of another container 10 through the opening 11. In the case where the hydrogen generating agent package 20 is placed in contact with the inner circumferential surface 14B of the container 10, the peripheral wall 14 is substantially thicker by the hydrogen generating agent package 20. When such hydrogen generating devices 1 are stacked as described above, the inserted hydrogen generating device 1 may be deformed, which reduces the commercial value. From this viewpoint, the hydrogen generating agent package 20 is preferably placed on the inner bottom surface 12A of the container 10. This also applies to the seventh embodiment described below.

[0092] <Fifth embodiment> The hydrogen generating device 1 in the fifth embodiment of the present invention will be described with reference to Fig. 10 to Fig. 13 and Fig. 27. The hydrogen generating device 1 in this embodiment has the same container portion 10, hydrogen generating agent packaging body 20, and outer packaging body 40 as the hydrogen generating device 1 in the first embodiment of the present invention, and therefore the description thereof will be omitted. The hydrogen generating device 1 in this embodiment differs from the hydrogen generating device 1 in the other embodiments in the configuration of the movement restriction portion 30.

[0093] 10(A) and (B), the movement restricting part 30 is configured with an extending part 38 extending from the opening 11 of the container part 10 toward the inside bottom surface 12A of the container part 10. The hydrogen generating agent packaging 20 is provided at one end of the extending part 38 or in its vicinity. A hook part 380 is provided at the other end of the extending part 38 or in its vicinity. The extending part 38 may be rod-shaped, band-shaped, or any other shape.

[0094] 10(A) and (B), the extension portion 38 is attached to the container portion 10 by an attachment mechanism 381. The attachment mechanism 381 is similar to the attachment mechanism 372 described in the above <Modification of the pressing-side peripheral wall>, and therefore a description thereof will be omitted.

[0095] The extension portion 38 preferably has a length that allows the extension portion 38 or the hydrogen generating agent package 20 to abut against the inner bottom surface 12A of the container portion 10 when the hook portion 380 is hooked onto the upper end of the peripheral wall 14 of the container portion 10. This is because the extension portion 38 or the hydrogen generating agent package 20 abuts against the inner bottom surface 12A of the container portion 10 to prevent the hydrogen generating agent package 20 from moving freely within the container portion 10. The extension portion 38 has a similar configuration to the belt-shaped wall 374 in the fourth embodiment.

[0096] The extending portion 38 holds the hydrogen generating agent package 20 in various modes. For example, in a band-shaped extending portion 38 provided with a through hole 382 as shown in FIG. 11(A), the hydrogen generating agent package 20 is inserted into the through hole 382 as shown in FIG. 12(A) so that the extending portion 38 holds the hydrogen generating agent package 20. The through hole 382 penetrates the extending portion 38 in the thickness direction of the extending portion 38. The through hole 382 is a vertically elongated hole formed in a band shape, and is provided on the opposite side of the hook portion 380 in the length direction of the extending portion 38 and in the center of the extending portion 38 in the width direction. The width of the through hole 382 in the width direction is approximately the same as or smaller than the thickness of the hydrogen generating agent package 20. The extending portion 38 is made of an elastically deformable material. As shown in FIG. 12(A), when the hydrogen generating agent packaging body 20 is inserted into the through hole 382, ​​the hydrogen generating agent packaging body 20 presses the strip pieces 383A, 383B located on either side of the through hole 382 in the width direction outward in the width direction, and is held by the extension portion 38 by being clamped by the strip pieces 383A, 383B due to the reaction force.

[0097] The through-hole 382 may be formed of a slit. The slit width of the slit is smaller than the thickness of the hydrogen generating agent packaging 20. If the extension portion 38 is formed of an elastically deformable material, the hydrogen generating agent packaging 20 presses the strip pieces 383A, 383B located on both sides of the slit in the width direction outward in the width direction, and the strip pieces 383A, 383B are clamped by the reaction force and held by the extension portion 38.

[0098] For example, in a band-shaped extending portion 38 provided with a slit 384 as shown in FIG. 11(B), the hydrogen generating agent package 20 is inserted into the slit 384, and the extending portion 38 holds the hydrogen generating agent package 20, as shown in FIG. 12(B). The slit 384 starts from an end of the extending portion 38 on the opposite side of the hook portion 380 in the length direction, and extends to the middle of the extending portion 38 in the length direction. The length of the slit 384 may be greater or smaller than the length of the hydrogen generating agent package 20 in the length direction. The extending portion 38 is made of an elastically deformable material. The hydrogen generating agent package 20 inserted into the slit 384 presses the band-shaped pieces 385A and 385B located on both sides of the slit 384 outward in the width direction, as shown in FIG. 12(B), and is sandwiched by the band-shaped pieces 385A and 385B due to the reaction force, and is held by the extending portion 38.

[0099] For example, in a band-shaped extending portion 38 provided with a clamping mechanism 386 as shown in FIG. 11(C), as shown in FIG. 12(C), the hydrogen generating agent package 20 is inserted into the clamping mechanism 386, and the extending portion 38 holds the hydrogen generating agent package 20. The clamping mechanism 386 has band-shaped pieces 387A and 387B. The band-shaped piece 387A constitutes one section in the longitudinal direction of the extending portion 38. Specifically, the band-shaped piece 387A constitutes a section from the middle of the extending portion 38 to the end of the extending portion 38 on the opposite side to the hook portion 380 in the longitudinal direction or the vicinity of the end. The band-shaped piece 387B is arranged in parallel with the band-shaped piece 387A in the thickness direction of the extending portion 38. Then, both ends in the longitudinal direction of the band-shaped piece 387B are connected to both ends in the longitudinal direction of the band-shaped piece 387A.

[0100] The strips 387A and 387A are configured so that the space between them can be expanded. In this case, the strips 387A and 387A are configured from an elastically deformable material. Alternatively, the strips 387A and 387A are configured so that at least one of them has a play in length so that a gap is formed between them into which the hydrogen generating agent package 20 can be inserted.

[0101] When the hydrogen generating agent packaging body 20 is inserted into the clamping mechanism 386, as shown in FIG. 12(C), the band-like pieces 387A, 387B are pressed outward in the width direction, and the hydrogen generating agent packaging body 20 is held by the extension portion 38 by being clamped by the band-like pieces 387A, 387B due to the reaction force.

[0102] 13(A), the hooking portion 380 may be configured to have a clamping portion 380A in which the distance of the U-shaped gap in the hooking portion 380 is approximately the same as or slightly smaller than the thickness of the upper end portion of the peripheral wall 14 of the container portion 10. In this case, the clamping portion 380A strongly clamps the upper end portion of the peripheral wall 14 of the container portion 10, so that when the clamping portion 380A is engaged with the upper end portion of the peripheral wall 14 of the container portion 10, the hydrogen generating agent package 20 together with the extension portion 38 is fixed in the container portion 10. The hooking portion 380 may not have the clamping portion 380A. In this case, as shown in FIG. 10(A), the distance of the U-shaped gap in the hooking portion 380 is greater than the thickness of the upper end portion of the peripheral wall 14 of the container portion 10.

[0103] However, in order to ensure that the hydrogen generating agent package 20 and the extension portion 38 are fixed in the container portion 10, a lid portion 60 may be provided to close the opening 11 of the container portion 10, as shown in Fig. 13(A). The lid portion 60 has a lid-side vent hole (or lid-side opening: the same applies below) 60B that opens the inside of the container portion 10 to the outside. Hydrogen generated in the container portion 10 is discharged to the outside through the lid-side vent hole 60B.

[0104] The hooking portion 380 straddles the upper end surface of the peripheral wall 14 of the container part 10 and is hooked to the peripheral wall 14. Therefore, when the opening 11 of the container part 10 is closed with the lid part 60, the inner side ceiling surface 60A of the lid part 60 presses the hooking portion 380 against the upper end surface of the peripheral wall 14 of the container part 10, as shown in FIG. 13(B). As a result, the hooking portion 380 is firmly clamped between the inner side ceiling surface 60A of the lid part 60 and the upper end surface of the peripheral wall 14 of the container part 10, and the hydrogen generating agent packaged body 20 together with the extension part 38 is fixed in the container part 10. If the lid part 60 is provided, the hydrogen generating agent packaged body 20 can be fixed in the container part 10 together with the extension part 38 even if the hooking portion 380 does not have the clamping portion 380A.

[0105] In addition, when the extension portion 38 does not have the hook portion 380, the lid portion 60 may be configured to have a through hole 60C through which the extension portion 38 passes, as shown in FIG. 13(C). The through hole 60C penetrates the inner ceiling surface 60A of the lid portion 60 in the thickness direction of the inner ceiling surface 60A. The through hole 60C may have a size and shape that allows the extension portion 38 to pass through when inserted. However, it is preferable that the through hole 60C has a size and shape that is approximately the same as, or slightly smaller or larger than, the cross section of the extension portion 38 cut in the thickness direction so that hydrogen generated in the container portion 10 does not leak from between the through hole 60C and the extension portion 38.

[0106] As shown in FIG. 13(D), when the lid 60 closes the opening 11 of the container 10, the extension 38 is inserted into the through hole 60C, and the upper portion 38A of the extension 38 passes through the through hole 60C and is positioned outside. That is, when the lid 60 closes the opening 11 of the container 10, the extension 38 is divided into an upper portion (extension-side outer section) 38A of the extension 38 that passes through the through hole 60C and is positioned outside, and an extension-side inner section 38B that is positioned inside the container 10. As a result, the extension 38 is restrained by the lid 60, and its movement is restricted. The extent to which the movement of the extension 38 is restricted is determined by the correlation between the through hole 60C and the size and shape of the extension 38.

[0107] The through hole 60C may be formed of a slit. The slit width of the slit is smaller than the thickness of the extension part 38. If at least the area around the slit in the lid part 60 is formed of an elastically deformable material, the slit is pushed open by the extension part 38, and the upper part (extension-side outer section) 38A of the extension part 38 passes through the slit and is positioned outside.

[0108] 27(A), the extension portion 38 may not have the hook portion 380. In this case, as shown in FIG. 27(B), when the extension portion 38 is inclined with respect to the container axial direction A inside the container portion 10, when the container portion 10 is covered with the lid portion 60, the lid side cover portion 60E comes into contact with the upper end of the extension portion 38 and presses the extension portion 38 downward. The lid side cover portion 60E refers to a portion of the lid portion 60 that faces the opening 11 of the container portion 10 and covers the opening 11. As a result, the extension portion 38 or the hydrogen generating agent package 20 is sandwiched between the lid side cover portion 60E and the bottom wall 12 and is fixed inside the container portion 10. The extension portion 38 has a length that allows the above-mentioned state. In order to prevent the extension portion 38 from sliding along the inner bottom surface 12A and losing its position, it is preferable that the extension portion 38 or the hydrogen generating agent packaging 20 abuts against the peripheral wall 14 as a stopper. Also, instead of the peripheral wall 14 as a stopper, a separate stopper (not shown) that protrudes from the inner bottom surface 12A may be provided on the bottom wall 12.

[0109] Sixth Embodiment With reference to FIG. 14, the hydrogen generating device 1 in the sixth embodiment of the present invention will be described. The hydrogen generating device 1 in this embodiment includes a container portion 10, a hydrogen generating agent package 20, and an external package 40, and does not include a movement restriction portion 30. Note that the external package 40 is not depicted in FIGS. 14(A) and (B). Therefore, in the hydrogen generating device 1 in the embodiment, when liquid is poured into the container portion 10, the hydrogen generating agent package 20 floats up to the water surface as shown in FIG. 14(B). As a result, only a part of the hydrogen generating agent package 20 (the side of the hydrogen generating agent package 20 facing the inner bottom surface 12A of the container portion 10) comes into contact with the liquid, and the rest does not come into contact with the liquid and comes into contact with the outside air. Such a case is also included in the scope of the present invention. Note that the container portion 10, the hydrogen generating agent package 20, and the external package 40 are the same as those of the hydrogen generating device 1 in the first embodiment of the present invention, and therefore their description will be omitted.

[0110] As shown in FIG. 15(A), the water level W of the liquid poured into the container 10 may be equal to or lower than the plane 20A (plane facing the opening 11) on one side of the hydrogen generating agent package 20 placed on the inner bottom surface 12A of the container 10 when the inner bottom surface 12A of the container 10 is used as a reference. In other words, the water level W may be equal to or lower than the thickness of the hydrogen generating agent package 20 when the inner bottom surface 12A of the container 10 is used as a reference. In this case, the hydrogen generating agent package 20 does not float up. As a result, the hydrogen generating agent package 20 maintains a state of contact with the inner bottom surface 12A of the container 10. Even in such an embodiment, the liquid can penetrate into the hydrogen generating agent package 20 and react with the hydrogen generating agent, so no problem occurs in use. In particular, the embodiment shown in FIG. 15(A) is advantageous in terms of cost because a small amount of liquid is sufficient.

[0111] As shown in Fig. 15(B), when the hydrogen generating agent package 20 floats up, the water level V of the liquid poured into the container 10 is preferably such that the opposing distance L between the inner bottom surface 12A of the container 10 and the flat surface 20B on the other side of the hydrogen generating agent package 20 in the container axial direction A is equal to or less than the thickness S of the hydrogen generating agent package 20 (S ≧ L). The embodiment shown in Fig. 15(B) is preferable from the viewpoint of hydrogen generation efficiency, since the contact area of ​​the hydrogen generating agent package 20 with the liquid is large, compared with the embodiment shown in Fig. 15(A). Also, since a small amount of liquid is sufficient, it is advantageous in terms of cost.

[0112] When separating the inner bottom surface 12A of the container portion 10 from the hydrogen generating agent package 20 in the container axial direction A, a pair of foot members 70 may be provided on the hydrogen generating agent package 20 as shown in FIG. 16(A). The pair of foot members 70 are provided on a flat surface 20B on one side of the hydrogen generating agent package 20 with a predetermined distance between them. The pair of foot members 70 have a base portion 71 and an upright portion 72. The base portion 71 is provided on the flat surface 20B. The upright portion 72 stands up from the flat surface 20B with the base portion 71 as a starting point. The upright portions 72 are provided at a predetermined distance between them and function as feet that support the hydrogen generating agent package 20.

[0113] As shown in Fig. 16(A), the standing portion 72 is foldably provided on the base portion 71. The base portion 71 and the standing portion 72 are integrally formed, for example, from waterproofed cardboard. The base portion 71 and the standing portion 72 are formed by making a U-shaped cut inside a rectangular piece of cardboard.

[0114] As shown in Fig. 16(B), when the hydrogen generating agent package 20 provided with a pair of leg members 70 is placed on the inner bottom surface 12A of the container part 10 so that the rising portion 72 and the inner bottom surface 12A of the container part 10 are in contact with each other, the inner bottom surface 12A of the container part 10 and the hydrogen generating agent package 20 are spaced apart in the container axial direction A. In this state, when liquid is poured into the container part 10 to the extent that the hydrogen generating agent package 20 is just immersed (water level T), a space is formed between the hydrogen generating agent package 20 and the inner bottom surface 12A of the container part 10 while the rising portion 72 is in contact with the inner bottom surface 12A of the container part 10. In this case, the amount of liquid to be reacted with the hydrogen generating agent can be increased while increasing the contact area of ​​the hydrogen generating agent package 20 in contact with the liquid.

[0115] The standing portion 72 is preferably made of a material having a higher specific gravity than water so that the hydrogen generating agent package 20 does not lose its position when liquid is poured into it. Even if the specific gravity is lower than water, a weight (not shown) may be provided to the foot member 70 so that the specific gravity of the foot member 70 as a whole is higher than that of water. The weight (not shown) may be provided to the hydrogen generating agent package 20.

[0116] Seventh Embodiment A hydrogen generating device 1 in a seventh embodiment of the present invention will be described with reference to Fig. 17. The hydrogen generating device 1 in this embodiment includes a container part 10, a storage part 29, and an external packaging body 40. The container part 10 and the external packaging body 40 are similar to those of the hydrogen generating device 1 in the first embodiment of the present invention, and therefore their description will be omitted. The storage part 29 stores the hydrogen generating agent 21 inside the container part 10, and has a plurality of fine ventilation holes 292 that pass the generated hydrogen to the outside. The fine ventilation holes 292 are of a size that does not allow particles of the hydrogen generating agent 21 to pass to the outside.

[0117] In this embodiment, as shown in Figs. 17(A) and (B), the storage section 29 is composed of an inner bottom surface 12A of the container section 10 and a storage side cover part 290 that covers the inner bottom surface 12A. The storage side cover part 290 covers the entire area or a part of the inner bottom surface 12A. An outer edge area 290A of the storage side cover part 290 is fixed to the inner bottom surface 12A or the inner peripheral surface 14B of the peripheral wall 14. The fixing method of the outer edge area of ​​the storage side cover part 290 is not particularly limited. An inner area 290B that is inside the outer edge area 290A is not fixed to the inner bottom surface 12A. Therefore, a storage space 291 is formed between the storage side cover part 290 and the inner bottom surface 12A of the container section 10. The hydrogen generating agent 21 is stored in the storage space 291.

[0118] The housing-side cover part 290 is provided with a plurality of fine vent holes 292 that allow hydrogen to pass to the outside. The fine vent holes 292 penetrate the housing-side cover part 290 in the container axial direction A. Note that, for the sake of explanation, the fine vent holes 292 are drawn in FIG. 17(B) but not drawn in FIG. 17(A). The fine vent holes 292 allow hydrogen generated from the hydrogen generating agent 21 to pass to the outside but are not large enough to allow the hydrogen generating agent 21 itself to pass through, and therefore are difficult to see with the naked eye. The housing-side cover part 290 is made of, for example, a sheet member made of nonwoven fabric or a sheet member braided with fibers. In this case, the fine vent holes 292 are made of gaps between fibers in the nonwoven fabric or meshes of the sheet member braided with fibers. After the sheet member is placed so as to cover the inner bottom surface 12A, the outer edge region of the sheet member is fixed to the inner bottom surface 12A or the inner peripheral surface 14B of the peripheral wall 14. The method of fixing the sheet member can be various, such as heat fusion or gluing, but is not limited to a specific method. A moisture blocking layer may be provided on the surface of the housing-side cover part 290 facing the hydrogen generating agent 21. The moisture blocking layer is similar to that described in the <First embodiment>, and therefore description thereof will be omitted.

[0119] In the third embodiment, the hydrogen generating agent package 20 is accommodated in the accommodation chamber 34, but the present invention also includes an embodiment in which the accommodation chamber 34 is configured to accommodate the hydrogen generating agent 21 as the accommodation section 29. In this case, it is necessary to design the size of the multiple holes so that the hydrogen generating agent 21 does not leak out of the accommodation chamber 34.

[0120] In this embodiment, the hydrogen generating agent 21 is directly accommodated in the accommodation space 291 (or the accommodation space 34A of the accommodation chamber 34) provided between the accommodation side cover part 290 and the inner bottom surface 12A of the container part 10. That is, in this embodiment, the hydrogen generating agent 21 is accommodated in the accommodation space 291 (or the accommodation space 34A of the accommodation chamber 34) so ​​as to be in contact with the accommodation side cover part 290 and the inner bottom surface 12A of the container part 10. Therefore, in this embodiment, the accommodation part 29 appears to be integrated with the container part 10 at the inner bottom surface 12A of the container part 10. As a result, in this embodiment, when viewed from the outside, it appears as if hydrogen is generated from the inner bottom surface 12A of the container part 10. On the other hand, in other embodiments, when viewed from the outside, it appears as if hydrogen is generated from the hydrogen generating agent package 20 as a separate member separable from the container part 10.

[0121] Also, the insulating layer 50 may be provided in the container part 10 below the bottom wall 12 in the container axial direction A. Specifically, the lower internal space 10C is provided in the container part 10 below the bottom wall 12 in the container axial direction A. That is, the lower internal space 10C is located below the internal space 10A in the container axial direction A. In the case of the above-mentioned structure, the container part 10 has a double bottom structure in which another bottom wall 15 is provided below the bottom wall 12 in the container axial direction A. The lower internal space 10C is surrounded by the bottom wall 12, the bottom wall 15, and the peripheral wall 14. If a material constituting an insulating layer is contained in the lower internal space 10C, that part becomes the insulating layer 50. An example of a material constituting an insulating layer is air. If the insulating layer 50 is provided, the degree to which heat generated during hydrogen generation is transmitted to the outside can be reduced. As a result, the user of the hydrogen generating device 1 does not feel hot even when holding it in his hand.

[0122] In this embodiment, the storage section 29 is described as being provided on the inner bottom surface 12A of the container section 10, but is not limited thereto and may be provided on the inner peripheral surface 14B of the container section 10. In this case, the storage section 29 is composed of the inner peripheral surface 14B of the container section 10 and a storage-side cover section 290 that covers the inner peripheral surface 14B. In other words, the storage section 29 includes all aspects in which the storage section 29 is provided on the inner side surface of the container section 10.

[0123] Moreover, the hydrogen generating agent package 20 and the movement restriction portion 30 in the <First embodiment> to the <Fifth embodiment>, and the hydrogen generating agent package 20 in the <Sixth embodiment> can be regarded as a storage portion that stores the hydrogen generating agent 21 inside the container portion 10 and has a plurality of holes that pass the generated hydrogen to the outside. As described above, the storage portion in the present embodiment may be independent of the container portion 10, like the hydrogen generating agent package 20, or may be configured in cooperation with a part of the container portion 10, like the storage side cover portion 290 and the inner side bottom surface 12A. Moreover, the hydrogen generating agent package 20 may be simply stored inside the container portion 10 without being restrained.

[0124] Eighth embodiment The hydrogen generating device 1 in the eighth embodiment of the present invention will be described with reference to Fig. 18. The hydrogen generating device 1 in this embodiment includes a container portion 10, a hydrogen generating agent packaging body 20 as a storage portion 29, and an outer packaging body 40. The container portion 10 and the outer packaging body 40 are similar to the hydrogen generating device 1 in the first embodiment of the present invention, and therefore description thereof will be omitted.

[0125] As shown in FIG. 18(A), the container part 10 has a base wall 16 that starts from the outer edge of the bottom wall 12 (external bottom surface 12B) and extends to the opposite side of the peripheral wall 14 in the container axial direction A. The base wall 16 is an annular wall that goes around the circumferential direction of the bottom wall 12 (external bottom surface 12B) along the outer edge of the bottom wall 12 (external bottom surface 12B). In this embodiment, the inner wall surface 16A of the base wall 16 and the outer bottom surface 12B of the bottom wall 12 form a recess 96 that is recessed in the container axial direction A on the bottom side of the container part 10. That is, the recess 96 is configured to be recessed in the container axial direction A on the outer side (external bottom surface 12B side) of the bottom wall 12 of the container part 10. The inner wall surface 16A of the base wall 16 is the inner peripheral surface of the base wall 16, and goes around the inner peripheral side of the base wall 16 in the circumferential direction to form a ring shape. The outer bottom surface 12B is the surface of the bottom wall 12 opposite to the inner bottom surface 12A. The inner bottom surface 12A faces the inner space 10A of the container 10 or the opening 11, whereas the outer bottom surface 12B faces the outer side. In this embodiment, the recessed space 97 surrounded by the recess 96 has a size capable of accommodating the hydrogen generating agent package 20 and the liquid container 95, as shown in FIG. 18(A), for example. The outer packaging body 40 covers and packages the container 10, the hydrogen generating agent package 20 accommodated in the recess 96, and the liquid container 95. The recess 96 is not limited to the above embodiment, and may be a recess of any embodiment. For example, the recess 96 may be configured to be recessed toward the inner side of the bottom wall 12 from the side surface 12C of the bottom wall 12 as a starting point, as shown in FIG. 28. The side surface 12C of the bottom wall 12 corresponds to an outer circumferential surface around the central axis of the bottom wall 12 that is parallel to the container axial direction A. The recess 96 is recessed in an orthogonal direction E that is perpendicular to the container axial direction A, for example.

[0126] 18(B), the liquid container 95 is, for example, a bag made of a resin film, in which a liquid for generating hydrogen in reaction with the hydrogen generating agent 21 is contained, and the bag opening is sealed by welding or the like. A slit 95C for opening is provided in the liquid container 95. The liquid container 95 is not limited to the above, and includes any that can contain liquid, and may be, for example, a container with a lid.

[0127] A moisture blocking layer 13 is provided on the outer bottom surface 12B. The hydrogen generating agent packaging 20 and the liquid container 95 are accommodated in the recessed space 97 and packaged by the outer packaging body 40 such that the flat surface 20A on one side of the hydrogen generating agent packaging 20 contacts the moisture blocking layer 13, the flat surface 20B on the other side of the hydrogen generating agent packaging 20 contacts the flat surface 95A on one side of the liquid container 95, and the flat surface 95B on the other side of the liquid container 95 contacts the outer packaging body 40. At this time, in order to prevent moisture from entering the hydrogen generating agent packaging 20 from the liquid container 95 side, a moisture blocking layer 82 made of a moisture blocking material is preferably provided on the flat surface 95A on one side of the liquid container 95 (a portion facing the hydrogen generating agent packaging 20 in the container axial direction A) as shown in FIG. 18(A).

[0128] 18(C), the hydrogen generating agent package 20 may be accommodated in the internal space 10A of the container 10, and only the liquid container 95 may be accommodated in the recessed space 97, similarly to the hydrogen generating device 1 in the first embodiment. The locations of the hydrogen generating agent package 20 and the liquid container 95 may be interchanged. Both the hydrogen generating agent package 20 and the liquid container 95 may be accommodated in the internal space 10A of the container 10.

[0129] In either case, however, it is preferable that a moisture blocking layer (not shown) made of a moisture blocking material is provided around the hydrogen generating agent package 20, such as the flat surface 20B on the other side of the hydrogen generating agent package 20, a position facing at least one of the flat surfaces 20A on one side of the hydrogen generating agent package 20, and a position facing the outer edge of the hydrogen generating agent package 20. The moisture blocking layer is provided on any one of the surfaces of the outer package 40, the liquid container 95, and the container portion 10.

[0130] <Ninth embodiment> A hydrogen generating device 1 in a ninth embodiment of the present invention will be described with reference to Fig. 19 and Fig. 20. The hydrogen generating device 1 in this embodiment includes a container part 10, a storage part 29, and a lid part 60. The container part 10 is similar to the hydrogen generating device 1 in the first embodiment of the present invention, and therefore a description thereof will be omitted. In addition, the storage part 29 may be any of those in the first to eighth embodiments including the hydrogen generating agent package 20.

[0131] <Lid> The lid part 60 will be described with reference to Figures 19 and 20. The lid part 60 covers the opening (container side opening) 11 of the container part 10 to close the opening 11. The lid part 60 has a lid side covering part 61, a lid side peripheral wall part 62, a ventilation side protrusion part 63, a ventilation side valve part 64, and a lid side protrusion part 65.

[0132] As shown in Figs. 20(A) and (B), the lid-side cover part 61 is a part that covers the opening 11 to close the opening 11. When the lid-side cover part 61 closes the opening 11 of the container part 10, the lid-side cover part 61 faces the bottom wall 12 or the storage part 29 (hydrogen generating agent package 20) in the container axial direction A (depth direction of the container part 10, the same applies below). In this embodiment, the lid-side cover part 61 is configured as an opposing wall 61A. In this embodiment, the opposing wall 61A is formed in a disk shape. The diameter (inner diameter of the lid part 60) of the opposing surface 61C of the opposing wall 61A on the side facing the bottom wall 12 or the storage part 29 (hydrogen generating agent package 20) is preferably slightly larger than or approximately the same as the outer diameter of the end part on the opening 11 side of the container part 10.

[0133] 19(B) and 20(B), the opposing wall 61A has a lid-side vent hole (or a lid-side opening) 610 that communicates between the outside and the inside of the container part 10. The lid-side vent hole 610 penetrates the opposing wall 61A in the thickness direction of the opposing wall 61A.

[0134] The lid-side peripheral wall portion 62 starts from the outer edge of the opposing wall 61A (lid-side covering portion 61) and extends around the circumferential direction of the outer edge of the opposing wall 61A (lid-side covering portion 61). It is preferable that the direction in which the lid-side peripheral wall portion 62 stands is approximately parallel to the direction in which the peripheral wall 14 of the container portion 10 extends when the opening 11 of the container portion 10 is closed by the lid portion 60, or is an intersecting direction that intersects with the direction in which the peripheral wall 14 of the container portion 10 extends.

[0135] The lid-side peripheral wall portion 62 has a lid-side recess 620 on its inner circumferential side. The lid-side recess 620 is recessed in the thickness direction of the lid-side peripheral wall portion 62, starting from the inner circumferential surface 62A of the lid-side peripheral wall portion 62. The lid-side recess 620 has a shape that can be fitted into the container-side protrusion 14F. The container-side protrusion 14F may be formed of an annular protrusion that goes around the circumferential direction of the peripheral wall 14 (around the container axial direction A), or may be formed of a protrusion that does not go around the entire circumference but extends only partially.

[0136] The lid-side peripheral wall 62 is formed of an elastically deformable material. Therefore, in the process of closing the opening 11 of the container 10 with the lid 60, the lid-side peripheral wall 62 is guided by the container-side protrusion 14F, elastically deforms, and spreads radially outward of the opposing wall 61A while moving toward the bottom wall 12 of the container 10 in the container axial direction A. At this time, when the lid-side recess 620 and the container-side protrusion 14F face each other in the radial direction of the opposing wall 61A, the container-side protrusion 14F fits into the lid-side recess 620, and the lid-side peripheral wall 62 is restored and deformed radially inward of the opposing wall 61A. As a result, the lid 60 is fixed to the container 10.

[0137] The ventilation side convex portion 63 is a portion that is convex from the lid side vent 610 toward (away from) the outside from the opposing wall 61A (lid side cover portion 61). The ventilation side convex portion 63 has a passage 630 inside. The passage 630 penetrates the ventilation side convex portion 63 in the convex direction of the ventilation side convex portion 63 and connects to both the outside and the lid side vent 610. As a result, the internal space 10A of the container portion 10 communicates with the external space through the passage 630 and the lid side vent 610 and is opened to the outside. The convex direction is a direction having a container axial direction A component. In this embodiment, the convex direction is parallel to the container axial direction A, but may be inclined with respect to the container axial direction A.

[0138] In this embodiment, the ventilation side protrusion 63 is formed in a cylindrical shape. The ventilation side protrusion 63 may be formed integrally with the opposing wall 61A as shown in FIG. 19(B) and FIG. 20(B). The ventilation side protrusion 63 may be formed by an insertion tube 640 inserted into the lid side ventilation hole 610 as shown in FIG. 21(A) and (B). The ventilation side protrusion 63 is formed by inserting the insertion tube 640 into the lid side ventilation hole 610. The insertion tube 640 is fixed to the lid side ventilation hole 610 by the clamping force of the lid side ventilation hole 610 or by another fixing means. The periphery of the insertion tube 640 is sealed by a seal member (packing) 650 on the opposing surface 61C side of the opposing wall 61A so that hydrogen does not leak from the internal space 10A through a gap between the insertion tube 640 and the lid side ventilation hole 610. The seal member (packing) 650 may be attached to the insertion tube 640 later, or may be provided in advance on the opposing surface 61C of the opposing wall 61A so as to fit in during the process of inserting the insertion tube 640.

[0139] 20(A) and (B), an external tube 200 can be connected to the ventilation side protrusion 63. An example of the external tube 200 is a cannula. When the external tube 200 is connected to the ventilation side protrusion 63, the passage 630 and the internal passage of the external tube 200 communicate with each other. As a result, the external tube 200 functions as an extension tube of the ventilation side protrusion 63.

[0140] The vent side valve section 64 opens and closes the lid side vent hole 610 (passage 630) to the outside. In this embodiment, the vent side valve section 64 is provided at an exterior side opening 631 of the passage 630 that communicates with the outside. The vent side valve section 64 opens when the pressure inside the container section 10 exceeds a threshold value. As shown in Figures 21(A) and (B), the vent side valve section 64 has, for example, a valve main body section 64A and a spring-loaded hinge 64B.

[0141] The valve body 64A opens and closes the exterior side opening 631 (passage 630) with the spring hinge 64B as a fulcrum. The spring hinge 64B is provided near the exterior side opening 631 of the ventilation side protrusion 63. The spring hinge 64B biases the valve body 64A in a direction to close. In a range in which the pressure inside the container 10 does not exceed a predetermined threshold, the biasing force of the spring hinge 64B is greater than the pressure inside the container 10, and the spring hinge 64B maintains a posture in which the exterior side opening 631 (passage 630) is closed. On the other hand, when the pressure inside the container 10 exceeds a predetermined threshold due to the generation of hydrogen, the spring hinge 64B is pressed in an opening direction by the pressure inside the container 10. As a result, the internal space 10A of the container 10 is opened to the outside, and the generated hydrogen flows to the outside.

[0142] The ventilation-side valve portion 64 may also include a position maintaining mechanism (not shown) that maintains the position in which the valve main body portion 64A forcibly opens the exterior-side opening 631 (passage 630) to the outside. The position maintaining mechanism may be configured to fix the valve main body portion 64A in an open position, for example, or may be configured to regulate the biasing force of the spring of the spring-loaded hinge 64B.

[0143] It should be noted that the vent side protrusion 63 may not be required. In a configuration without the vent side protrusion 63, hydrogen is discharged to the outside through the lid side vent 610. In a configuration without the vent side protrusion 63, a valve portion (not shown) that opens and closes the lid side vent 610 is provided in the lid side vent 610. This valve portion has a similar structure to the vent side valve portion 64. Additionally, the present invention also includes configurations in which the vent side valve portion 64 and a valve portion (not shown) that opens and closes the lid side vent 610 are not provided.

[0144] The provision of the vent side valve portion 64 makes it possible to restrict the discharge of unnecessary hydrogen from the inside to the outside of the container portion 10. Furthermore, by adding a position maintaining mechanism (not shown) to the vent side valve portion 64, hydrogen can be discharged from the inside of the container portion 10 to the outside whenever the user wishes to inhale hydrogen.

[0145] The lid-side protrusion 65 in this embodiment is formed by a ring-shaped wall that starts from the outer side surface 61B of the opposing wall 61A (lid-side cover portion 61) facing the outside of the container portion 10 and protrudes away from the opposing wall 61A, and goes around the outer side surface 61B along the outer side surface 61B. The lid-side protrusion 65 protrudes in a direction having a container axial direction A component. In this embodiment, the lid-side protrusion 65 is formed as a cylindrical wall 65A extending in the container axial direction A, as shown in FIG. 19(A). The space 600 surrounded by the inner wall surface 65B of the cylindrical wall 65A and the outer side surface 61B has a size capable of accommodating the hydrogen generating agent package 20 and / or the liquid container 95. In addition, when the inner circumferential side of the lid-side protrusion 65 is viewed, it can be understood that a lid-side recess 65F is formed. That is, it can be understood that the lid-side protrusion 65 has a lid-side recess 65F that is open to the outside on the inner side. The space surrounded by the lid-side recess 65F corresponds to the space 600. The hydrogen generating agent package 20 and / or the liquid container 95 are placed such that at least a part of their flat surface abuts against the outer side surface 61B. The hydrogen generating agent package 20 and / or the liquid container 95 are preferably accommodated so as not to protrude from the space 600 even if the effective overall length is reduced by folding or curving the hydrogen generating agent package 20 and / or the liquid container 95. Taking these factors into consideration, the shape and size of the space 600 (the height and inner diameter of the cylindrical wall 65A) are determined.

[0146] In this embodiment, the lid side ventilation hole 610 and the ventilation side protrusion 63 are provided on the outer side surface 61B so as to be aligned in parallel with the lid side protrusion 65, as shown in FIG. 22(A), but are not limited thereto. For example, as shown in FIG. 22(B), the lid side ventilation hole 610 and the ventilation side protrusion 63 may be provided on the outer side surface 61B in the space 600 surrounded by the lid side protrusion 65. Also, for example, as shown in FIG. 22(C), the lid side protrusion 65 may be configured as an arc wall 65C provided in an arc shape, rather than an annular shape. Also, as shown in FIG. 22(D), the lid side protrusion 65 may be configured by two discontinuous arc walls 65D and 65E. Also, for example, as shown in FIG. 22(E), the lid side protrusion 65 may be a polygonal tube shape, such as a rectangular tube shape, rather than a cylindrical shape.

[0147] The lid-side protrusion 65 is not limited to the arc walls 65C to 65E or the polygonal tubular shape. In other words, the lid-side protrusion 65 is convex from the outer side surface 61B of the lid-side cover part 61 facing the outer side of the container part 10, and may extend continuously or discontinuously along the outer side surface 61B so as to form a space 600 surrounded by the lid-side protrusion 65. Therefore, the lid-side protrusion 65 may be, for example, a curved surface whose inner circumferential surface goes around continuously or discontinuously. The lid-side protrusion 65 may be, for example, a plane whose inner circumferential surface goes around continuously with adjacent planes intersecting, or a plane whose inner circumferential surface goes around discontinuously in a state in which the extensions of adjacent planes may intersect. The lid-side protrusion 65 may be, for example, a curved surface whose inner circumferential surface does not go around but does form a surrounding space 600, or a discontinuous curved surface. The lid side protrusion 65 may be, for example, a plane in which the inner circumferential surface forms the surrounding space 600 without going all the way around, and adjacent planes intersect and are continuous, or a discontinuous plane in which the inner circumferential surface forms the surrounding space 600 without going all the way around, and extended planes of adjacent planes may intersect. Various combinations of the above aspects of the lid side vent 610, the vent side protrusion 63, and the lid side protrusion 65 are also included in the scope of the present invention.

[0148] <How the hydrogen generator works> The operation of the hydrogen generating device 1 in this embodiment will be described with reference to Figs. 19 and 20. In the state shown in Figs. 19(A) and (B), the hydrogen generating agent package 20 accommodated in the space 600 surrounded by the lid-side convex portion 65 (or the lid-side concave portion 65F) is taken out and placed inside the container portion 10, and the hydrogen generating agent package 20 is placed on the inside bottom surface 12A of the container portion 10. Then, liquid is poured into the inside of the container portion 10. At this time, as shown in Figs. 20(A) and (B), for example, the water level W is set to a level at which the entire hydrogen generating agent package 20 is immersed or less. In other words, the water level W is about the thickness of the hydrogen generating agent package 20 based on the inside bottom surface 12A of the container portion 10. It should be noted that more liquid may be poured. The container portion 10 is covered with the lid portion 60.

[0149] In the case where the vent valve portion 64 is not provided, when hydrogen is generated by reaction between the liquid and the hydrogen generating agent, the hydrogen passes through the lid vent hole 610 of the lid portion 60 and the passage 630, and is discharged to the outside from the outside opening 631 of the vent convex portion 63. The user inhales the hydrogen. This allows the user to efficiently take in hydrogen into the body.

[0150] On the other hand, when the vent side valve section 64 is provided, hydrogen accumulates in the internal space 10A of the container section 10 with the vent side valve section 64 closing the passage 630. Then, when the pressure in the internal space 10A of the container section 10 exceeds a predetermined threshold value due to hydrogen, the vent side valve section 64 opens the external side opening 631 (passage 630) to the outside. Note that when the vent side valve section 64 is provided, the vent side valve section 64 may close the passage 630 when the user wants to inhale hydrogen, so that when the user wants to inhale hydrogen, the vent side valve section 64 can be forced to open the external side opening 631 (passage 630) to the outside by a posture maintaining mechanism (not shown).

[0151] Tenth Embodiment The hydrogen generating device 1 in the tenth embodiment of the present invention will be described with reference to Fig. 23. As shown in Fig. 23(A), the hydrogen generating device 1 in this embodiment is obtained by adding a storage unit 80 to the hydrogen generating device 1 in the first embodiment.

[0152] The storage unit 80 has a storage space 800 therein for storing gas (hydrogen) discharged to the outside through the passage 630 of the ventilation side protrusion 63. The storage unit 80 has a connection part 81 that can be detachably connected to the ventilation side protrusion 63 so that the storage space 800 and the space in the passage 630 communicate with each other. The connection part 81 is formed of a first storage side protrusion 83 that is convex starting from a first storage side hole 80A provided in the storage unit 80. The first storage side protrusion 83 is formed, for example, of a tube having an insertion path 830 that penetrates in a convex direction inside the first storage side protrusion 83. The ventilation side protrusion 63 is configured to be able to be inserted into the insertion path 830 while being in close contact with the insertion path 830. In other words, the shape and size of the first storage side protrusion 83 and the ventilation side protrusion 63 are configured so that hydrogen does not leak to the outside from the connection part between the first storage side protrusion 83 and the ventilation side protrusion 63. Furthermore, a fixing portion (not shown) may be provided to maintain the state in which the first storage side protrusion 83 is inserted into the ventilation side protrusion 63. The storage portion 80 as described above is, for example, configured by a bag body. The bag body is preferably configured by a material that can contract and expand (scale up and down). Examples of such materials include resins such as vinyl, and paper.

[0153] Hydrogen generated from the hydrogen generating agent packaging 20 (storage section 29) within the container section 10 is discharged to the outside through the passage 630, but by connecting the storage section 80 to the ventilation side protrusion 63, it is possible to store a certain amount of hydrogen that would normally be released into the atmosphere and wasted.

[0154] 23(B), second storage side hole 80B may be provided separately in storage unit 80, and second storage side convex portion 84 having passage 840 therein may be provided starting from second storage side hole 80B. Passage 840 penetrates second storage side convex portion 84 in the convex direction. Insertion path 830 and passage 840, first storage side hole 80A and second storage side hole 80B have substantially the same configuration as ventilation side convex portion 63. Hydrogen in storage space 800 is discharged to the outside through passage 840. At this time, if the pressure in storage space 800 becomes too high due to hydrogen stored in storage unit 80, storage unit 80 may burst, so a storage side valve 85 for opening and closing passage 840 may be provided.

[0155] Storage-side valve 85 is provided at exterior-side opening 841 of passage 840 communicating with the outside. Storage-side valve 85 opens when the pressure inside storage portion 80 (storage space 800) exceeds a threshold value. The structure of storage-side valve 85 is similar to that of vent-side valve portion 64. In the case of a configuration without second storage-side protrusion 84, a valve (not shown) that opens and closes second storage-side hole 80B is provided in second storage-side hole 80B.

[0156] Eleventh Embodiment The hydrogen generating device 1 in the eleventh embodiment of the present invention will be described with reference to Fig. 24. As shown in Fig. 24(A), the hydrogen generating device 1 in this embodiment is configured such that a lid-side insertion hole 660 separate from the lid-side ventilation hole 610 is provided in the opposing wall 61A (lid-side cover portion 61) of the hydrogen generating device 1 in the first embodiment.

[0157] The lid-side insertion hole 660, like the lid-side vent hole 610, penetrates the opposing wall 61A in the thickness direction of the opposing wall 61A and communicates between the outside and the inside of the container part 10. The lid-side insertion hole 660 has a size and shape that allows an external tube to be inserted therein.

[0158] The lid-side insertion hole 660 is provided with an insertion-side valve portion 661 on the inside of the container portion 10. The insertion-side valve portion 661 opens when a pressing force equal to or greater than a predetermined threshold is applied to the insertion-side valve portion 661 from the outside toward the inside of the container portion 10. Specifically, the insertion-side valve portion 661 opens when pressed with a predetermined pressing force (a force equivalent to a predetermined threshold) by a tube inserted into the lid-side insertion hole 660. On the other hand, the insertion-side valve portion 661 is configured not to open with a force from the inside of the container portion 10 toward the outside. In other words, the insertion-side valve portion 661 functions as a check valve. The specific configuration of the insertion-side valve portion 661 is the same as that of the vent-side valve portion 64 (valve body portion and spring-loaded hinge), so the description of the vent-side valve portion 64 is also applicable here.

[0159] <Hydrogen-containing water production device and production method> A hydrogen-containing water producing device capable of producing hydrogen-containing water can be configured using the hydrogen generating device 1 in this embodiment. The hydrogen-containing water producing device will be described below with reference to Fig. 25. The hydrogen-containing water producing device includes a hydrogen generating device 1 on the hydrogen generating side that generates hydrogen, a container part 10 and a lid part 60 on the hydrogen receiving side that receives the generated hydrogen, and an air pipe 90 that connects the hydrogen generating side and the hydrogen receiving side.

[0160] First, as shown in FIG. 25(A), water is poured into the hydrogen receiving vessel 10 (right side of FIG. 25(A)). Then, one end 90A of the vent pipe 90 is inserted into the lid side insertion hole 660 of the lid 60 of the hydrogen generating device 1 on the hydrogen generating side (left side of FIG. 25(A)) to connect to the hydrogen generating device 1 on the hydrogen generating side. Note that, as shown in FIG. 25(B), one end 90A of the vent pipe 90 may be directly inserted into the vent side protrusion 63, instead of the lid side insertion hole 660. In addition, when the lid 60 in the ninth embodiment is applied to the hydrogen receiving vessel 10, the lid side insertion hole 660 is removed from FIG. 25(B). Such a configuration is also included in the scope of the present invention.

[0161] The other end 90B of the vent pipe 90 is inserted into the lid-side insertion hole 660 in the lid part 60 on the hydrogen receiving side to connect to the lid part 60. At this time, the vent pipe 90 is inserted until the other end 90B of the vent pipe 50 is located near the inner bottom surface 12A of the container part 10 on the hydrogen receiving side. The other end 90B of the vent pipe 90 may be inserted into the vent side protrusion 63. Such an arrangement is also within the scope of the present invention.

[0162] In this state, water is poured into the container 10 of the hydrogen generating device 1 on the hydrogen generating side to react with the hydrogen generating agent package 20 and the hydrogen generating agent. As a result, hydrogen is generated and moves to the container 10 on the hydrogen receiving side through the vent pipe 90. The hydrogen is discharged from the other end 90B of the vent pipe 50 into the water inside the container 10 on the hydrogen receiving side. During this process, the hydrogen dissolves in the water inside the container 10 on the hydrogen receiving side. The undissolved hydrogen is discharged to the outside through the lid-side vent 610 of the lid 60 on the hydrogen receiving side and the passage 630 of the vent-side protrusion 63.

[0163] As described above, while hydrogen moves through the vent pipe 90 to the hydrogen receiving container 10, hydrogen can be discharged to the outside through the passage 630 of the vent side protrusion 63 in the hydrogen generating device 1 on the hydrogen generating side. In other words, with the hydrogen generating device 1 in this embodiment, the user can inhale hydrogen while producing hydrogen-containing water.

[0164] In the hydrogen-containing water producing apparatus, one end 90A of the vent pipe 90 may be inserted into the vent side protrusion 63 of the hydrogen generating device 1 on the hydrogen generation side. In the hydrogen-containing water producing apparatus, it is sufficient that the hydrogen generating device 1 on the hydrogen generation side is provided with only one of the vent side protrusion 63 and the lid side insertion hole 660.

[0165] <Twelfth embodiment> The hydrogen generating device 1 in the twelfth embodiment of the present invention will be described with reference to Fig. 26. As shown in Fig. 26, the hydrogen generating device 1 in this embodiment can accommodate not only the hydrogen generating agent package 20 but also a liquid container 95 in a space 600 surrounded by an inner wall surface 65B of a cylindrical wall 65A of the hydrogen generating device 1 in the first embodiment and an outer side surface 61B of an opposing wall 61A.

[0166] The liquid container 95 is similar to that described in the eighth embodiment (see FIG. 18(B)). That is, the liquid container 95 is, for example, a bag made of a resin film in which liquid is contained, and the mouth of the bag is sealed by welding or the like. The liquid container 95 is provided with a slit 95C for opening. Note that the liquid container 95 is not limited to the above, and includes any that can contain liquid, and may be, for example, a container with a lid.

[0167] In the hydrogen generating device 1 in this embodiment, the hydrogen generating agent package 20 and the liquid container 95 are stacked on the outer side surface 61B of the opposing wall 61A along the container axial direction A and are contained in a space 600 surrounded by the cylindrical wall 65A. Note that an embodiment in which only the liquid container 95 is contained in the space 600 is also included in the scope of the present invention.

[0168] <Thirteenth embodiment> The hydrogen generating device 1 in the thirteenth embodiment of the present invention will be described with reference to Figures 29 and 30. As shown in Figure 29(A), the hydrogen generating device 1 in this embodiment is the hydrogen generating device 1 in the ninth embodiment of the present invention (see Figure 19) provided with a container side filter 18, a lid side air hole filter 18A, a container side window portion 19, and a lid side window portion 19A.

[0169] <filter> When the hydrogen generating agent reacts with the liquid in the container 10, hydrogen is generated. At this time, hydrogen bubbles may burst when they jump out from the liquid surface, causing the liquid to scatter in the form of lumps of a certain size. Furthermore, when the scattered lumps of liquid pass through the passage 630 of the ventilation side protrusion 63 and jump out to the outside, the lumps of liquid may reach the user of the hydrogen generating device 1. The container side filter 18 is provided to capture the scattered lumps of liquid before they jump out to the outside. For this reason, the container side filter 18 is capable of capturing the lumps of liquid that jump out with the generation of hydrogen, but is made of a material having filter side ventilation holes (mesh: net) large enough to pass the hydrogen-containing gas generated from the hydrogen generating agent 21. Examples of such materials include nonwoven fabric, but are not limited to this, and other materials may also be used.

[0170] The scattered lump of liquid passes through the passage 630 of the ventilation side protrusion 63 and is thrown out to the outside. For this reason, the container side filter 18 is disposed at any position on the path through which the scattered lump of liquid passes from the inner side bottom surface 12A of the bottom wall 12 of the container part 10 to the passage 630, as shown in Figs. 29(A) and (B). Specifically, the container side filter 18 is disposed, for example, in the container part 10 at a position spaced apart from the inner side bottom surface 12A of the container part 10 by a predetermined height K in the container axial direction A. The container side filter 18 is configured to extend over the entire area surrounded by the inner circumference at that position. For this reason, the container side filter 18 divides the internal space 10A of the container part 10 in the container axial direction A in two at that position. That is, the container side filter 18 divides the internal space 10A into an opening proximal side space 10D and an opening distal side space 10E. When the container-side filter 18 is provided in this manner, the container-side filter 18 blocks all paths of the splashed liquid mass at that position, and all of the splashed liquid mass is captured by the container-side filter 18.

[0171] The container-side filter 18 may extend to a part of the area surrounded by the inner circumference at the above-mentioned position. In this case, the container-side filter 18 preferably extends to an area closer to the lid-side vent 610 than the center of the above-mentioned area.

[0172] The lid-side air hole filter 18A is provided so as to block and cover the opening 610A of the lid-side air hole 610 on the back side of the lid part 60. As a result, a lump of liquid that splashes toward the lid-side air hole 610 is captured by the lid-side air hole filter 18A and cannot pass through the lid-side air hole 610.

[0173] Furthermore, a lid-side passage filter (not shown) made of the same material as the container-side filter 18 and the lid-side vent filter 18A and having a filter-side vent (second filter-side vent) configured in the same manner as the lid-side vent filter 18A may be provided at any position along the passage 630 or to block and cover the exterior-side opening 631 of the passage 630. If provided in this manner, it is possible to prevent a lump of scattered liquid from splashing out to the outside.

[0174] At least one of the container-side filter 18, the lid-side air hole filter 18A, and the lid-side passage filter may be provided. However, since the lid-side air hole filter 18A or the lid-side passage filter is easier to manufacture than the container-side filter 18, the lid-side air hole filter 18A or the lid-side passage filter can be manufactured at a lower cost.

[0175] <Window section> The container-side window 19 is made of a transparent material and is provided so as to form a partial area of ​​the peripheral wall 14 of the container part 10. Since the container-side window 19 is made of a transparent material, a user of the hydrogen generating device 1 can visually check the inside of the container part 10 from the outside through the container-side window 19, as shown in FIG.

[0176] The container side window 19 is provided to allow the user of the hydrogen generator 1 to see the hydrogen generated. The hydrogen generated can be confirmed as bubbles in the liquid. For this reason, the container side window 19 is preferably provided in an area where the liquid can be seen. An example of such an area is an area that starts from the lowest end of the peripheral wall 14 or its vicinity, spreads in the container axial direction A toward the opening 11, and spreads in the circumferential direction of the peripheral wall 14, but is not limited thereto. In other words, as long as bubbles in the liquid can be confirmed through the container side window 19, the container side window 19 may be provided at any position on the peripheral wall 14. For example, if the liquid level in the container part 10 is low, it is preferable that the container side window 19 be provided as close as possible to the lowest end of the peripheral wall 14, and if the liquid level in the container part 10 is high, the container side window 19 may be provided at any position.

[0177] Furthermore, the entire container 10 may be made of a transparent material. In this case, the entire container 10 can be regarded as constituting the container-side window 19.

[0178] The lid side window 19A is made of a transparent material and is provided so as to form a partial area of ​​the lid side covering part 61 of the lid part 60. Since the lid side window 19A is made of a transparent material, a user of the hydrogen generating device 1 can see the inside of the container part 10 from the outside through the lid side window 19A, as shown in FIG.

[0179] Incidentally, the lid-side window 19A, like the container-side window 19, is provided to allow the user of the hydrogen generating device 1 to see the generated hydrogen. Since the lid-side window 19A allows the entire liquid to be visually confirmed from above the liquid, the generated hydrogen bubbles can be confirmed no matter where the lid-side window 19A is provided on the lid-side cover part 61.

[0180] Furthermore, the entire lid portion 60 or the entire lid side covering portion 61 may be made of a transparent material. In this case, the entire lid portion 60 or the entire lid side covering portion 61 can be considered to constitute the lid side window portion 19A.

[0181] In this embodiment, both the container side window portion 19 and the lid side window portion 19A are provided, but this is not limited thereto, and only one of them may be provided.

[0182] The hydrogen generating device of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. In addition, the present invention also includes hydrogen generating devices, containers, and lids that are constructed by arbitrarily combining the respective components in the first to thirteenth embodiments. [Industrial Applicability]

[0183] The hydrogen generating device of the present invention may be configured by accommodating a nonwoven fabric bag containing a hydrogen generating agent (hydrogen generating agent package 20) in a paper or plastic cup (container 10). The bag is placed on the inside bottom surface of the cup. The hydrogen generating device of the present invention may also be configured by affixing a nonwoven fabric sheet around the outer edge of the inside bottom surface of a paper or transparent plastic cup (container 10). The hydrogen generating agent is accommodated between the inside bottom surface and the nonwoven fabric sheet. The above-mentioned hydrogen generating device is sold at convenience stores, and hydrogen is generated simply by pouring water into the cup. The user inhales the generated hydrogen for health reasons through the lid-side vent 610 or the vent-side protrusion 63. [Explanation of symbols]
