Description

The present invention relates to a hydrogen gas inhalation device and a hydrogen gas inhalation set.

In recent years, there has been growing interest in the potential of taking hydrogen gas into the body to maintain and improve health. Inhaling hydrogen gas into the body is said to remove active oxygen species such as hydroxyl radicals, which are deeply involved in numerous diseases such as aging, cancer, diabetes, and high blood pressure, and it is being incorporated into advanced medical treatments.

Hydrogen gas is a gas that can be easily produced by electrolysis of water, and Patent Document 1 describes an invention for an inhaler that inhales hydrogen gas generated by electrolysis of water. This inhaler is small enough to be carried around in a bag or the like, and has a large number of parts, such as a built-in battery that supplies power for electrolysis, a control means for controlling the power supply, and a mesh electrode plate connected to a titanium electrode in the electrode section, which makes the operation related to hydrogen gas generation complicated and inevitably expensive.
Since this suction device is made small so that it can be carried around, it is limited in terms of electrode area and battery capacity, and can only generate a relatively small amount of hydrogen gas in a short period of time.

Meanwhile, Patent Document 2 describes an invention for a small, lightweight, portable hydrogen gas inhaler that does not rely on water electrolysis. This device has a cylindrical case that houses a tubular nonwoven fabric with closed front and rear ends and a hydrogen gas generator made of magnesium powder, citric acid powder, and powdered cellulose. The front end of the cylindrical case is filled with a water-retaining material, and the rear end is filled with a water-absorbing material. This cartridge is attached to the holder of the inhaler and hydrogen gas is inhaled.

In the hydrogen gas inhalation device described in Patent Document 2, when the tip of the cartridge containing the hydrogen gas generator is immersed in water stored in a container or cup for a few seconds and then pulled out, the water is retained in the water-retaining material packed into the tip of the cartridge. This retained water then permeates the interior of the hydrogen gas generator due to the water-absorbing effect of the powdered cellulose, and the magnesium reacts with citric acid to generate hydrogen gas.
When the generated hydrogen gas begins to be sucked through the suction port of the holder, water is supplied to the hydrogen gas generator from the water-retaining material at the tip of the cartridge, and the reaction continues, generating hydrogen gas for a predetermined period of time.

The hydrogen gas inhalation device described in Patent Document 2 has a cartridge containing a hydrogen gas generator that is approximately 5 cm long, and the holder is also approximately 7 cm long, so it can be carried in a bag, handbag, or clothing pocket.
However, in this invention, hydrogen gas is generated by immersing the tip of the cartridge in water stored in a container or cup for a specified period of time and then pulling it up.However, because the hydrogen gas generation reaction occurs from the tip of the cartridge to the rear end, great care must be taken in operations such as how the tip of the cartridge is immersed in water and how it is tilted, making it somewhat difficult to stably generate hydrogen gas to be inhaled.In addition, it takes time for the hydrogen gas generation reaction to be completed from the tip to the rear end of the cartridge, making it impossible to inhale a relatively large amount of hydrogen gas in a short period of time.

Patent No. 6464385 Patent No. 6436325

In light of these circumstances, the present invention aims to provide a hydrogen gas inhalation device and hydrogen gas inhalation set that can be carried in a bag or handbag, generates hydrogen gas stably with simple operation, and allows for the inhalation of relatively large amounts of hydrogen gas in a short period of time.

In order to solve the above problems, the present invention employs the following means.
[1] A hydrogen gas inhalation device consisting of a paper cup shaped like an inverted truncated cone and a lid, which generates hydrogen gas by spraying water onto a nonwoven fabric package containing a hydrogen gas generator placed in the paper cup, wherein the lid comprises a lid body that fits over the top of the opening of the paper cup, a nozzle portion that serves as a hydrogen gas inhalation port formed on the lid body, and a ring portion and multiple plate-shaped hanging portions formed on the back surface of the lid body, wherein the ring portion is shaped like an inverted truncated cone, and when the lid body is fitted over the top of the opening of the paper cup, the outer surface of the ring portion contacts the inner surface of the opening of the paper cup, and the lower end of the plate-shaped hanging portion extends below the lower edge of the ring portion and is formed by joining an upper portion of one side surface to the inner surface of the ring portion, and when the lid body is fitted over the top of the opening of the paper cup, the lower portion of one side surface of the plate-shaped hanging portion is close to or contacts the inner surface of the paper cup.
[2] The hydrogen gas inhalation device described in [1], characterized in that the tip of the nozzle portion is covered with a mouthpiece having an inhalation hole formed therein.
[3] The hydrogen gas inhalation device described in [1] or [2], characterized in that the nozzle portion or the suction hole of the mouthpiece is filled with a sponge.
[4] A hydrogen gas inhaler according to any one of [1] to [3], characterized in that an aromatic ball is inserted into the nozzle portion or the suction hole of the mouthpiece.
[5] A hydrogen gas inhalation set comprising a combination of a hydrogen gas inhalation device according to any one of [1] to [4], a nonwoven fabric package containing a hydrogen gas generator, and a water container containing water to be sprayed onto the nonwoven fabric package.

The hydrogen gas inhalation device of the present invention and the hydrogen gas inhalation set including it are small and comprised of a paper cup and lid, making them easy to carry in a purse or handbag. Furthermore, hydrogen gas is generated by spraying water directly onto the nonwoven fabric packaging containing a hydrogen gas generator housed in the paper cup, and the lid is then attached to the paper cup, allowing for inhalation through the nozzle provided on the lid. This allows for simple operation to generate and inhale hydrogen gas to be inhaled. Furthermore, because hydrogen gas is generated by spraying water directly onto the nonwoven fabric packaging containing a hydrogen gas generator housed in the paper cup, hydrogen gas can be generated reliably and stably, and a relatively large amount can be generated in a short period of time.

An embodiment of the hydrogen gas suction tool of the present invention will be described with reference to the drawings.
Figure 1 shows a hydrogen gas suction device.
Here, 1 is a hydrogen gas suction tool, 2 is a paper cup, 3 is a lid, 31 is the lid body, 32 is a nozzle part that serves as a hydrogen gas suction port, 33 is a circular ring part, and 34 is a plate-shaped hanging part.
The hydrogen gas inhalation device 1 comprises a paper cup 2 and a lid 3. A nonwoven fabric package containing a hydrogen gas generator is placed inside the paper cup 2, and hydrogen gas is generated when water is sprayed onto the package. A person wishing to inhale hydrogen gas attaches the lid 3 to the paper cup 2 and inhales hydrogen gas through the nozzle 32 of the lid 3. The annular portion 33 and the plate-shaped hanging portion 34 will be described later.

A paper cup 2 is shown in Figure 2. As shown in this figure, the paper cup 2 has an inverted truncated cone shape, i.e., an upside-down truncated cone shape, and is stackable. The upper edge of the opening of the paper cup 2 is usually rolled outward, forming a curl 21. The curl 21 is not necessarily required.
The paper cup 2 can be laminated with a polyethylene film to make it heat-resistant and waterproof. Such paper cups are commercially available and well known.

The lid 3 is shown in Figures 3 and 4. Figure 3(a) is a perspective view of the lid 3 as seen from the front side, and Figure 3(b) is a perspective view of the lid 3 as seen from the back side. Figures 4(a) to 4(c) show a front view, a bottom view, and a vertical cross-sectional view of the lid 3.
The lid body 3 comprises a lid main body 31 that fits onto the upper end of the opening of the paper cup 2, a nozzle portion 32 that protrudes from the front side of the lid main body 31, a circular ring portion 33 that is formed on the back side of the lid main body 31, and multiple plate-shaped hanging portions 34.
The nozzle portion 32 has a suction hole formed therein, which serves as a suction port for hydrogen gas. In Figures 1, 3 and 4, the nozzle portion 32 is formed in the center of the lid body 31, but it does not have to be in the center.

A side portion is formed around the periphery of the lid body 31 of the lid 3, and as shown in Figures 1(b) and 4(c), this side portion has a step portion 311 that protrudes outward. When the lid 3 is attached to a paper cup, the outer edge of this step portion 311 fits over the upper edge of the opening of the paper cup 2, and if a curl 21 is formed at the upper edge of the opening of the paper cup, it fits over this curl 21.

A circular ring portion 33 having a low, hollow, generally cylindrical shape resembling an inverted truncated cone is formed on the periphery of the back surface of the lid body 31. This periphery is located slightly inside the outer periphery of the stepped portion 311, and a gap is formed between the outer periphery of the stepped portion 311 and the circular ring portion 33. When the lid body 3 is attached to the paper cup 2, the top end of the opening of the paper cup fits into this gap, and the lid body 3 fits onto the paper cup 2.
The height of the annular portion 33 may be 15 to 40% of the height of the cup, and the formation of the annular portion 33 makes the lid body 31 itself less likely to deform.

As shown in Figures 3 and 4, the annular portion 33 has the same inverted truncated cone shape as the paper cup 2, so the outer diameter of the annular portion 33 changes depending on the height position, but the outer diameter of the annular portion 33 is made equal to the inner diameter of the opening of the paper cup 2, which changes depending on the height direction. In this way, when the lid 3 is attached to the paper cup 2, the outer surface of the annular portion 33 comes into contact with the inner surface of the opening of the paper cup 2, and the lid 3 fits into the opening of the paper cup 2.

On the inner surface of the annular portion 33, a plurality of plate-shaped hanging portions 34 are formed at intervals from the rear surface of the lid body 31 toward the center of the lid body 31 (see FIG. 4(b)). The lower ends of the plate-shaped hanging portions 34 reach below the lower edge of the annular portion 33 (see FIGS. 4(a) and 4(c)).
There are no restrictions on the position of the lower end of the plate-shaped hanging portion 34 as long as it does not come into contact with the bottom of the paper cup 2, but it is effective to position it below the lower edge of the annular portion 33 and to a position between the bottom of the paper cup 2 and half the height from the top of the opening.

One side of plate-shaped hanging portion 34 is joined to the inner side of the peripheral edge of lid body 31 from the back surface of lid body 31 until it reaches the position of the upper edge of the annular portion, and is further joined to the inner surface of annular portion 33 from the position of the upper edge of the annular portion to the position of the lower edge. Then, below the position of the lower edge of annular portion 33, one side of plate-shaped hanging portion 34 extends downward so as to be parallel to the inclined surface of the inner surface of the inverted truncated cone-shaped paper cup, or so as to be tangent to this inclined surface, i.e., so as to extend downward more vertically.
The other side of the plate-shaped hanging portion 34 extends vertically downward from the rear surface of the lid body 31, as shown in FIG. 1(b) and FIG. 4(c).

By doing this, when the lid 3 is fitted onto the paper cup 2, the opening at the top of the paper cup 2 can be firmly supported by the annular portion to which the upper portion of the plate-shaped hanging portion 34 is joined. Furthermore, below the opening at the top of the paper cup 2, the lower portion of one side of the plate-shaped hanging portion 34 (the portion below the lower edge of the annular portion 33) can be made to be close to or in contact with the inner surface of the paper cup 2, so that the lower portion of one side of the plate-shaped hanging portion 34 can also be close to or in contact with the paper cup 2, acting on the paper cup 2 in the same way as a reinforcing rib.

Therefore, when the lid 3 is attached to the paper cup 2 and fits into the opening of the paper cup 2, the top of the opening of the paper cup 2 is supported by the stepped portion 311 on the outer periphery of the lid body 31, and the opening of the paper cup 2 is supported by the annular portion 33 to which the upper portion of the plate-shaped hanging portion 34 is joined, and further, below the opening of the paper cup 2, the lower portion of one side of the plate-shaped hanging portion 34 is close to or in contact with the side of the paper cup 2, so that the paper cup 2 does not easily deform even when the paper cup 2 with the lid 3 attached is gripped. At this time, the opening of the paper cup 2 is sealed by the stepped portion 311 and the annular portion 33 of the lid body 31, and therefore hydrogen gas inside the paper cup 2 does not leak out from the fitting surface between the lid 3 and the paper cup 2.
In addition, when the lower portion of one side of the plate-shaped hanging portion 34 is close to the side of the paper cup 2, it is preferable that the gap between the two sides is approximately 0.25 mm or less at the closest point.

It is desirable to form three or more, preferably five or more, plate-shaped hanging portions 34 at equal intervals on the back surface of the lid 3. In Figures 3 and 4, five plate-shaped hanging portions 34 are formed.
The width of plate-shaped hanging portion 34 is approximately half the radius of annular portion 33 or less in the example shown in Figure 4(b), but it may be greater than that. It is also preferable to form a radius (roundness) at the bottom end of plate-shaped hanging portion 34.

The lid body 3 can be manufactured by injection molding a resin material, for example, to integrally form the lid body 31, nozzle portion 32, annular portion 33, and multiple plate-shaped hanging portions 34. A similar integral lid body 3 can also be manufactured from a paper material. Note that while the upper edge of the annular portion 33 is shown with a solid line in Figures 1(b), 3(b), and 4(c), it is formed integrally so that there is no step at the boundary between the inner surface of the back side of the lid body 31 and the inner surface of the annular portion 33.

The nonwoven fabric packaging 4 containing the hydrogen gas generator is placed in the bottom of the paper cup 2, and hydrogen gas is generated when water is sprayed onto it. The lid 3 is attached to the paper cup 2, and hydrogen gas can be sucked through the nozzle 32 of the lid 3.
FIG. 5 shows an example of a nonwoven fabric package 4 containing a hydrogen gas generator.

The nonwoven fabric packaging 4 containing the hydrogen gas generator can be produced, for example, by folding a rectangular nonwoven fabric in half and sealing the combined width edges to form a bag, placing the hydrogen generator inside through the opening, and then closing the opening. As the nonwoven fabric, for example, a food-grade nonwoven fabric used for tea bags and the like can be used.
When water is sprayed onto the nonwoven fabric packaging 4 containing the hydrogen gas generator, the water easily passes through the nonwoven fabric and permeates the hydrogen gas generator, generating hydrogen gas.

A mixture containing metallic magnesium and citric acid can be used as a hydrogen gas generator that generates hydrogen gas by spraying water, but as described in Patent Document 2, it is preferable to use a mixture of magnesium powder, citric acid powder, and powdered cellulose. When water is sprayed onto this mixture, the magnesium and citric acid react to generate hydrogen gas. Hydrogen gas is generated by the reaction between magnesium and citric acid. This reaction does not generate oxygen gas, as occurs with the electrolysis of water.
The term "particulate material" as used herein means that the particles constituting the particulate material include powder-like particles and granular particles having a particle size of about 1 mm or less.

When using a mixture of magnesium powder granules, citric acid powder granules, and powdered cellulose, preventing the materials from separating will allow the chemical reaction to continue and enable more stable and efficient generation of hydrogen gas. Therefore, it is desirable to use an agglomerated mixture of the three materials: magnesium powder granules, citric acid powder granules, and powdered cellulose. The agglomeration method is also described in Patent Document 2.

When approximately 3 g of hydrogen gas generators made by mixing magnesium powder, citric acid powder, and powdered cellulose in a mass ratio of approximately 1:3 to 9:1 to 3 and granulating them is placed in a nonwoven fabric package and reacted by spraying water, a total of approximately 150 ml of hydrogen gas can be generated per minute. In this case, approximately 2.5 cc of water is required for the reaction, but to be on the safe side, 3 to 5 cc of water sprayed is sufficient.

As mentioned above, the hydrogen gas generator may weigh approximately 3 grams, and the nonwoven fabric packaging body 4 containing the hydrogen gas generator can be flat with a closing margin of approximately 8 mm, with a length and width of approximately 50 mm and a thickness of approximately 8 mm, including the closing margin.
The flat nonwoven fabric packaging body 4 containing hydrogen gas can be placed so as to contact the bottom of the paper cup 2, provided that the area of the bottom of the paper cup 2 is equal to or greater than the area calculated from the length and width of the packaging body 4.

The hydrogen gas inhaler 1 can be carried in a bag or handbag together with the nonwoven fabric package 4 containing the hydrogen gas generator, so that hydrogen gas can be inhaled anywhere water is available.
The water to be sprayed onto the nonwoven fabric packaging 4 containing the hydrogen gas generator can be taken from a water faucet or a plastic bottle, but it may also be taken from a water container 5 such as a portable water pack, a stick-type water package, or a sauce bottle-type water container.

6 to 8 show examples of the water container 5, such as a water pack, a stick-type water package, and a sauce bottle water container, respectively.
The water pack shown in Figure 6 is a flat, transparent resin film encasing water, but it does not have to be transparent. Also, if a slit is made in the adhesive margin at the edge of the water pack, it can be torn from the slit and the enclosed water can be easily sprayed.
The stick-type water package shown in Figure 7 is also a long piece (the long side is longer than the short side) in which water is wrapped in a laminated film of polyethylene resin and aluminum foil. In this case too, if a slit is made in one end, it can be torn from the slit and the enclosed water can be easily sprayed.
The sauce bottle-type water container shown in FIG. 8 is a small container with a cap, and water can be sprayed by removing the cap.

The water container 5 only needs to contain water corresponding to the amount of hydrogen gas generator. If the hydrogen gas generator weighs about 3 g, 3 to 5 cc of water will be sufficient, so it can be made large enough to fit into the paper cup 2.
If such a water container 5 is carried in a bag or handbag together with the nonwoven fabric package 4 containing the hydrogen gas generator, hydrogen gas can be conveniently inhaled wherever one is, even when there is no water available.
In addition, the use of a water container allows the amount of water to be sprayed in proportion to the amount of hydrogen gas generator, thereby avoiding the situation where too little water is sprayed, resulting in insufficient hydrogen gas being generated, or the situation where too much water is sprayed.

Hydrogen gas is generated when water is sprayed onto the nonwoven fabric packaging 4 containing the hydrogen gas generator placed at the bottom of the paper cup 2. At this time, the water is sprayed directly onto the nonwoven fabric packaging 4 containing the hydrogen gas generator, so the water quickly penetrates the hydrogen gas generator in the nonwoven fabric, causing a reliable reaction and stable generation of hydrogen gas. In addition, the state of water penetrating into the nonwoven fabric packaging 4 containing the hydrogen gas generator inside the paper cup 2 can be easily confirmed visually.
In this way, the person who inhales can spray water directly onto the nonwoven fabric packaging 4 containing the hydrogen gas generator inside the paper cup 2, then attach the lid 3 and immediately inhale the hydrogen gas through the nozzle portion 32 of the lid, allowing for stable generation and inhalation of hydrogen gas with simple operations.

As already mentioned, by spraying water onto a nonwoven fabric package containing about 3 g of a hydrogen gas generator, it is possible to generate approximately 150 ml of hydrogen gas per minute. The suction device described in Patent Document 2 generates at most about 80 ml of hydrogen gas in 15 minutes. Furthermore, the suction device described in Patent Document 1 is a small electrolysis type, so the amount of hydrogen gas generated is thought to be at most a few ml per minute.
In this way, the suction device of the present invention can suck a relatively large amount of hydrogen gas in a short time, and can shorten the time spent sucking a predetermined amount of hydrogen gas.

The reaction between the magnesium hydrogen generator and citric acid is exothermic, so when hydrogen is generated inside the paper cup 2, the surface of the paper cup may reach approximately 50°C. This can be addressed by using an insulating paper cup 2, such as one with an embossed finish, or by wrapping a cardboard sleeve around the paper cup.

A person can inhale hydrogen gas through the nozzle portion 32 of the lid, but they can also inhale hydrogen gas through the mouthpiece 6, which has a hole formed at the tip of the nozzle portion 32. A hole is formed in the center of the mouthpiece 6 through which hydrogen gas inhaled through the nozzle portion 32 can pass. Figure 9 shows a perspective view of the hydrogen gas inhaler with the mouthpiece 6 placed over the nozzle portion 32.

Pieces of sponge are stuffed into the suction hole of the nozzle part 32 and the hydrogen gas passage hole of the mouthpiece 6 to prevent the generated hydrogen gas from flowing out directly into the outside air from the hydrogen gas suction hole or passage hole of the nozzle part 32 or the mouthpiece 6. Even if sponge pieces are stuffed in, there is almost no problem with inhaling the hydrogen gas because hydrogen gas molecules are extremely small.
Alternatively, an aromatic ball (flavor ball) may be sandwiched between two pieces of sponge and inserted into the suction hole of the nozzle or the passage hole of the mouthpiece. This allows the user to inhale fragrant hydrogen gas, giving the user the feeling that they are inhaling hydrogen gas.
The mouthpiece 6 can be easily washed by removing it from the nozzle portion 32. Furthermore, if a sponge or an aromatic ball is placed in the mouthpiece 6, the mouthpiece 6 can be removed from the nozzle portion 32 and the sponge or aromatic ball can be easily replaced.

There is no particular restriction on the size of the hydrogen gas inhalation device 1 as long as it is small enough to be held by a person, but if the hydrogen gas generator packaged in the nonwoven fabric packaging body 4 weighs about 3 g, the height of the paper cup 2 and the diameter of the opening can be about 50 mm, the diameter of the bottom can be about 40 mm, and the length of the nozzle part 32 of the lid body can also be about 40 mm, and the total length (height) of the hydrogen gas inhalation device 1 with the lid body 3 attached to the paper cup 2 can be about 90 mm.
In this case, the amount of water in the water container 5 needs to be about 3 to 5 cc, so either type of water container 5 can be sized to fit into a paper cup 2 with a height of about 50 mm, an opening diameter of about 50 mm, and a bottom diameter of about 40 mm.

Carrying a complete hydrogen gas inhalation set that combines a nonwoven fabric package 4 containing a hydrogen gas generator, a water container 5, and a hydrogen gas inhalation device 1 makes it convenient to inhale hydrogen gas even in places where water is difficult to obtain. In this case, if the nonwoven fabric package 4 containing the hydrogen gas generator and the water container 5 are stored in the paper cup 2 of the hydrogen gas inhalation device 1 and the hydrogen gas inhalation device 1 is carried in a bag or handbag, the items needed for inhaling hydrogen gas can be quickly accessed as a set, making it even more convenient.

The paper cup 2 is disposable after each inhalation of hydrogen gas, and the lid 3 can be reused.
The paper cups 2 are stackable, so it is possible to carry multiple stacked paper cups 2. It is also possible to carry multiple paper cups by stacking paper cups 2 containing a nonwoven fabric package 4 containing a hydrogen gas generator, or paper cups 2 containing a nonwoven fabric package 4 containing a hydrogen gas generator and a water container 5.

The present invention allows hydrogen gas to be inhaled with simple operation, and the hydrogen gas inhalation device is a relatively inexpensive device consisting of a disposable paper cup and a reusable lid, so it meets the expectations of people who want to inhale hydrogen gas on a daily basis.
