Description

  The present invention relates to a hydrogen gas supply unit.

  Hydrogen water in which hydrogen gas is dissolved in water is widely used as drinking water. Hydrogen water is said to have an anti-aging effect because it can remove active oxygen in the body by reducing power when taken into the body.

  Today, this hydrogen water is sold by filling a solution of hydrogen gas in water into a beverage container at a manufacturing plant. As a manufacturing apparatus of this hydrogen water, the apparatus of Unexamined-Japanese-Patent No. 2005-177724 is proposed, for example.

JP 2005-177724 A

  However, hydrogen gas dissolved in water is easy to degas. For this reason, even if the hydrogen concentration at the time of manufacture at the manufacturing plant is moderate, the hydrogen gas has been degassed during transportation and storage, and the hydrogen concentration is extremely low when the purchaser ingests it. And hydrogen is often completely lost.

  As a result, depending on the hydrogen water produced by the conventional method, it is difficult to remove the active oxygen in the body and it is difficult to obtain a desired effect.

  This invention is made | formed based on such a situation, and makes it a subject to provide the hydrogen gas supply unit which can manufacture easily a hydrogen-containing drink with a high hydrogen concentration at the time of ingestion reliably.

  The hydrogen gas supply unit according to the present invention, which was made to solve the above problems, is a hydrogen gas supply unit for supplying hydrogen gas into a beverage contained in a beverage container having a cylindrical opening, A portable hydrogen gas supply container having a discharge portion that contains hydrogen gas and can discharge the hydrogen gas, and a lid that is fitted to the mouth of the beverage container and is detachably connected to the discharge portion.

[Hydrogen gas supply unit]
The said hydrogen gas supply unit supplies hydrogen gas in the drink accommodated in the drink container X which has the cylindrical opening part X1. The hydrogen gas supply unit is fitted into a portable hydrogen gas supply container 1 having a discharge portion 2 in which hydrogen gas is stored and capable of releasing the hydrogen gas, and a mouth portion X1 of the beverage container X, and the discharge portion 2 and a lid 21 detachably connected. Further, the hydrogen gas supply unit includes a hydrogen gas filling connector 31 for filling the portable hydrogen gas supply container 1 with hydrogen gas stored in a hydrogen gas storage tank (not shown).

  An example of the usage method of the said hydrogen gas supply unit is demonstrated. The user carries the portable hydrogen gas supply container 1 and the lid 21, fits the lid 21 to the mouth X 1 of the beverage container X immediately before ingesting the beverage stored in the beverage container X, and further carries the portable type. The hydrogen gas in the portable hydrogen gas supply container 1 is injected into the beverage container X by connecting the hydrogen gas supply container 1 and the lid 21. The user terminates the injection of hydrogen gas by releasing the connection between the portable hydrogen gas supply container 1 and the lid 21, removes the lid 21 from the mouth X 1, and then stores the hydrogen contained in the beverage container X. Ingest the beverage. Further, when the hydrogen gas in the portable hydrogen gas supply container 1 decreases, the user fills the portable hydrogen gas supply container 1 with hydrogen gas from a separately provided hydrogen gas storage tank (not shown). The hydrogen gas filling is performed with the hydrogen gas filling connector 31 and the portable hydrogen gas supply container 1 in a state where the hydrogen gas filling connector 31 is connected to a hydrogen gas discharge tube (not shown) of the hydrogen gas storage tank. And the hydrogen gas filling connector 31 by connecting them.

The container body 3 is made of metal such as aluminum and stainless steel, for example. The container main body 3 includes a bottomed cylindrical barrel portion 3a, a cylindrical reduced diameter portion 3b continuous from the opening side end of the barrel portion 3a, and a cylindrical mouth portion 3c continuous from the reduced diameter portion 3b. Have. The discharge part 2 is connected and fixed to the mouth 3 c by a screw or the like.

  The lower limit of the axial length of the container body 3 is preferably 5 cm, more preferably 7 cm. On the other hand, as an upper limit of the axial direction length of container main part 3, 15 cm is preferred and 9 cm is more preferred. If the axial length is shorter than the lower limit, the hydrogen gas storage capacity becomes insufficient, the hydrogen gas filling frequency may be unnecessarily increased, and the handleability of the portable hydrogen gas supply container 1 may be reduced. is there. Conversely, when the axial length exceeds the upper limit, it may be difficult to store the portable hydrogen gas supply container 1 in a pocket or the like of the clothes, and the portability may be insufficient.

The lower limit of the volume of the container body 3, preferably 5 cm ^3, 7 cm ³ is more preferable. On the other hand, as an upper limit of the volume of container main part 3, 15 cm ³ is preferred and 10 cm ³ is more preferred. If the above-mentioned volume does not reach the above-mentioned lower limit, the storage capacity of hydrogen gas becomes insufficient, and there is a possibility that the filling frequency of hydrogen gas may become unnecessary unnecessarily. On the other hand, when the volume exceeds the upper limit, the size of the portable hydrogen gas supply container 1 becomes large, and there is a possibility that the portability is insufficient.

  The container body 3 contains hydrogen gas. More specifically, the container body 3 contains a hydrogen storage alloy, and the hydrogen storage alloy contains hydrogen gas or compressed hydrogen gas.

The casing 22 has a tubular shape having a through hole in the axial direction, and the hydrogen gas suction nozzle 24, the second valve 25 and the second spring member 26 are disposed in the through hole. The casing 22 and the hydrogen gas suction nozzle 24 are both formed of a rigid member such as metal. The hydrogen gas suction nozzle 24 is a straight tube. On the base end side of the casing 22 (the side opposite to the side connected to the discharge part 2), a cylindrical fitting part 27 to be fitted with the opening X1 of the beverage container X is formed. On the inner peripheral surface of the fitting portion 27, a female screw 28 that can be screwed into the mouth portion X1 of the beverage container X is provided. The central axis of the hydrogen gas suction nozzle 24 and the central axis of the fitting portion 27 coincide with each other.

  When the hydrogen gas suction nozzle 24 and the second valve 25 are urged by the second spring member 26, the lid 21 has a space in the hydrogen gas suction nozzle 24 and a space in the fitting portion 27 by the second valve 25. Is blocked. On the other hand, when the hydrogen gas suction nozzle 24 is pressed to the base end side, the lid 21 moves the second valve 25 together with the hydrogen gas suction nozzle 24 to the base end side, whereby the space in the hydrogen gas suction nozzle 24 And the internal space of the fitting portion 27 communicate with each other. The pushable distance of the hydrogen gas suction nozzle 24 may be predetermined in terms of structure.

  Since the hydrogen gas supply unit is provided with the anti-slip O-ring 11 on the outer peripheral surface of the first connecting part 6, the first connecting part 6 and the second connecting part when injecting hydrogen gas into the beverage container X are provided. It is easy to maintain the fitting state of the part 23. That is, the O-ring 11 functions as a stopper for preventing the first connection when stress is exerted in the direction in which the fitting of the first connection portion 6 and the second connection portion 23 is released by the release of hydrogen gas. The omission of the portion 6 and the second connection portion 23 can be prevented, whereby the hydrogen gas leakage can be suppressed.
