Description

  The present invention relates to a gas generating inner lid for dissolving carbon dioxide gas or hydrogen gas in water in a container such as a PET bottle, water such as various drinking water or liquor, or an aqueous solution without scattering outside the container.

  Soft drinks in which carbon dioxide gas is dissolved in drinking water have been known for a long time. Recently, water that has dissolved hydrogen gas has begun to appear on the market because it contributes to human health. Water in which hydrogen gas is dissolved is called hydrogen water, and its production method is roughly classified into two types. One is a method in which hydrogen gas is dissolved under pressure in drinking water at a factory or the like and filled in a container (Patent Document 1). The other method is to use a hydrogen generator such as magnesium metal powder that reacts with water to generate hydrogen. The hydrogen generator is placed in a container containing water and sealed, and the generated hydrogen is dissolved in water. This is a method for adjusting hydrogen water (Patent Document 2).

  Hydrogen has the lowest molecular weight in a gas, and therefore, even if hydrogen water is adjusted and sealed in a container, there is a drawback that it is diffused during storage. Therefore, even if hydrogen water is adjusted and packed in a container at the factory, hydrogen will be scattered from the container during storage and distribution, and when it reaches the consumer, the dissolved hydrogen concentration in water (DH is abbreviated). However, there was a drawback that would be reduced. On the other hand, the method using a hydrogen generating agent can adjust the hydrogen water just before drinking the hydrogen water, so the above problems can be solved, but magnesium metal has a slow reaction with water and adjusts the hydrogen water. It takes time to do this, and there are disadvantages that unreacted metal residues remain in water.

  The present inventor recently developed a novel hydrogen generator using a hydrogen compound such as magnesium hydride (MgH 2) or calcium hydride (CaH 2), which has a fast reaction with water, and solved these drawbacks (Patent Literature). 3). However, since these hydrogen generators react quickly with water depending on the type and composition of the hydrogen compound, hydrogen is generated while the hydrogen generator is put into a container containing water and sealed, and the container opens. A problem has been found that dissipates into the air from the club.

  When gas is dissolved in water using a gas generating agent that reacts or dissolves with water and generates gas in a short time, the generated gas is dissolved in water without being diffused into the air.

  An inner lid of a container that is attached to an opening of the container and is covered with an outer lid of the container to be sealed, and the inner lid has an internal space surrounded by a partition, and a part of the partition is The spherical body is solved by using an inner lid of a sealed container that is movable when the container is tilted or inverted after the container is sealed with an inner lid and an outer lid.

  In the inner lid, it is preferable that there are pores penetrating the partition wall in the partition walls other than the spherical body, and there is a removal prevention tool for preventing the spherical body from detaching from the inner space of the inner lid when inclined or inverted. An existing inner lid is preferred.

    By using the inner lid of the present invention, the gas of the gas generating agent that reacts or dissolves with water and generates a gas in a short time can be dissolved in the water in the container without being diffused into the atmosphere.

FIG. 1 shows an example of the inner lid of the present invention. a) is a sectional view thereof, and b) is a top view thereof. FIG. 2 is a cross-sectional view of a state in which the inner lid of FIG. 1 is inserted into the opening of the container, a gas generating agent is placed in the inner lid, and the container is sealed with the outer lid. FIG. 3 is a cross-sectional view of the closed container of FIG. 2 in an inverted state. FIG. 4 shows another example of the inner lid of the present invention. a) is a sectional view thereof, and b) is a top view thereof. FIG. 5 shows another example of the inner lid of the present invention. a) is a sectional view thereof, and b) is a top view thereof. FIG. 6 is an upright view and an inverted view of the container in a state where the container containing water is sealed using the inner lid and the outer lid of the present invention.

  The gas generating agent to which the present invention is effectively used reacts or dissolves with water and generates gas in a short time, and carbon dioxide gas and hydrogen gas can be considered as the gas. Typical examples of the carbon dioxide generator include a mixture of a bicarbonate such as sodium bicarbonate or sodium carbonate or a carbonate and an organic acid such as citric acid, succinic acid or oxalic acid. In addition, when water is an aqueous solution in which the above bicarbonate or carbonate is dissolved, an organic acid is a carbon dioxide generator, and if water already contains an acid such as citric acid, acetic acid or hydrochloric acid, Bicarbonate and carbonate are carbon dioxide generators.

  On the other hand, as a gas generating agent that generates hydrogen gas in a short time in contact with water, alkali metal hydrides such as lithium hydride and sodium hydride, hydrogen such as magnesium hydride (MgH2) and calcium hydride (CaH2) Examples thereof include alkaline earth metal borohydrides, metal borohydrides such as sodium borohydride and potassium borohydride. All of these hydrogen generating agents generate hydrogen by chemically reacting with water, and the reaction rate differs depending on the type of the hydrogen generating agent, but all are markedly faster than magnesium metal.

  MgH2 and borohydride metal salts increase the reaction rate in the presence of acid. On the other hand, CaH2 does not require the presence of an acid and reacts with water remarkably quickly. Therefore, in order to slow down the reaction rate, it is preferably used as a hydrogen generator that is melted and embedded in a water-soluble compound such as trehalose or polyethylene glycol to slow down the reaction rate. Moreover, since CaH2 and MgH2 react with water and become alkaline, when the aqueous solution in which hydrogen is dissolved needs to be neutral, the above-mentioned organic acids and the like and these alkaline earth metal hydrides are used for the purpose of neutralization. It is necessary to mix and use the hydrogen generator or to dissolve the hydrogen generator in an aqueous solution that has been adjusted to be acidic in advance.

  These gas generating agents can be stored in the inner space of the inner lid in various forms such as powder, tablet, and block. Since these gas generating agents react with a very small amount of water to generate gas, when stored, it is preferable to store in a sealed state in a humidity-free state such as an aluminum bag.

  The inner lid of the present invention is inserted into the opening of a container containing water so that it does not come into contact with water during use, and is sealed with a means such as a screw method or a mating method with a sealing outer lid. At that time, the gas generating agent is put in the inner space of the inner lid in advance and the gas generating agent is not brought into contact with water until the container is sealed with the outer lid (upright view in FIG. 6). Since the movable spherical body constituting the inner lid partition wall moves to the inner space of the inner lid by tilting or inverting the container after sealing, water in the container enters the inner space of the inner lid. Gas is generated in contact with the gas generating agent (inverted view of FIG. 6).

  Since the generated gas cannot be diffused outside the container, it collects in the space of the container, and the inside of the container is in a pressurized state according to the amount of the generated gas. Since the gas is generated as fine bubbles, a part of the gas is dissolved in the water while moving in the upper space. Further, since the gas collected in the upper space is in a pressurized state, the gas dissolves in water according to the partial pressure. In this way, the gas can be effectively dissolved in water. When the gas dissolution is completed, the sealed container is returned to the upright state, the outer lid is opened, the inner lid is taken out, and the water in the container can be used.

    Such a function that allows the generated gas to be completely dissolved in the air without letting it escape into the air can be used not only for efficiently adjusting hydrogen water or carbonated water for beverages but also in analytical techniques. For example, in the case of carbonated water, carbon dioxide is generated from sodium hydrogen carbonate and an organic acid such as citric acid and dissolved in water to prepare carbonated water. In that case, since 1 mol of carbon dioxide gas is generated from 1 mol of sodium hydrogen carbonate from the chemical reaction formula, the concentration of carbon dioxide contained in the carbonated water is theoretically determined. That is, when the carbon dioxide concentration of carbonated water in which the carbon dioxide gas generated by this reaction is completely dissolved without being released into the air is measured by the gas chromatographic method, the area of the chromatograph is equal to the theoretical carbon dioxide concentration. This leads to the creation of an accurate calibration curve required in the analysis technique.

The case where a polyethylene terephthalate bottle (hereinafter abbreviated as PET bottle) is used as a container and gas is dissolved in water using the inner lid of the present invention will be described below with reference to the drawings. FIG. 1 is an example of the inner lid of the present invention. The material is exemplified by metal, ceramic, plastic, etc., but plastic is preferable from the viewpoint of workability. a) is a cross-sectional view thereof, b) is a top view, and 1 is a main body of an inner lid, which is a cylindrical side partition that can be inserted into an opening of a PET bottle, and a movable part that forms a part of the partition. The inner space 2 is formed by a possible spherical body 3.

  FIG. 2 is a cross-sectional view of a state in which water is poured into the PET bottle 4, the powdered gas generating agent 5 is introduced into the inner lid of FIG. 1 and inserted into the bottle opening, and the bottle is sealed with the outer lid 6. 7 is a packing material for maintaining hermeticity. By processing the spherical body 3 close to a true sphere, the sealing of the bottom of the inner lid is maintained and the powdery gas generating agent is prevented from spilling from the inner lid.

  FIG. 3 is a cross-sectional view of the sealed PET bottle of FIG. 2 in an inverted state. The movable spherical body is dropped from the bottom of the inner lid by gravity and water pressure due to inversion, and moves to the outer lid. At the same time, the gas generating agent also falls, but the partition formed by the spherical body disappears, so water enters and comes into contact with the gas generating agent to generate gas at once. Reference numeral 8 denotes gas bubbles.

  FIG. 4 is a view showing another example of the inner lid of the present invention. a) is a sectional view thereof, and b) is a top view thereof. In this example, a plurality of through-holes 9 are provided in the upper part of the cylindrical side partition wall, so that when the sealed container is inverted, water intrusion becomes even easier than in the example of FIG.

  FIG. 5 is a view showing another example of the inner lid of the present invention. a) is a sectional view thereof, and b) is a top view thereof. In this example, when the gas generator and water are brought into contact with each other and the gas is generated, the container is kept upright and opened to drink the water in which the gas is dissolved. The removal prevention tool 10 is provided in the upper part of the internal space without leaving the internal space of the inner lid. The detachment prevention tool may be fixed to the inner lid or detachable.

    The water that can be used in the present invention is not limited to pure water, but can be applied to all types of tea, mineral water, natural water, juices, shochu and liquor. Also included are acid and alkaline water. In addition to cosmetics, cosmetics such as skin lotions and cosmetic liquids can be adjusted to cosmetics that can be expected to have a whitening effect and a blood circulation promoting effect by dissolving hydrogen and carbon dioxide during use. Hereinafter, the present invention will be described in more detail with reference to examples.

    A mixture of anhydrous trehalose and adipic acid was melted on a hot plate, and sodium sulfate, magnesium sulfate and calcium hydride (CaH2) were added and mixed and stirred. The mixture was cooled and solidified to obtain a hydrogen generator in which CaH2 was melted and embedded. The solidified mixture was pulverized with a pulverizer to prepare a powdered hydrogen generator. When 1 g of this hydrogen generator was reacted with water, 30 ml (25 ° C.) of hydrogen was generated.

  The inner lid of FIG. 4 that can be inserted into the opening of a PET bottle, which is a commercially available 500 ml carbonated water container, was made of polycarbonate resin. The outer diameter of the cylindrical side partition wall was 18 mm, and the height including the flange portion was 25 mm. A 1.5 mm through-hole was provided on the circumference of the four circles in the upper part of the cylindrical partition. In order for an acrylic spherical body having a diameter of 10 mm to sit on the cylindrical bottom, a circular cut surface having a diameter of 7 mm was cut with a taper. Further, an outer lid for sealing the PET bottle was made of polycarbonate resin.

  500 ml of tap water was placed in a commercially available 500 ml carbonated water PET bottle, and the inner lid made as a trial was sufficiently dried and then inserted into the container opening so as not to come into contact with water. 1 g of the above hydrogen generating agent was placed in the inner space of the inner lid and sealed with a prototype outer lid, and the PET bottle was inverted. Simultaneously with the inversion, the spherical body in the inner lid fell to the outer lid, and fine bubbles were generated vigorously for 30 seconds. Thereafter, the bottle was kept upright for 5 minutes, the bottle was returned to the upright state, and the outer lid was opened. The hydrogen generator in the inner lid was completely dissolved, and transparent hydrogen water was obtained. It was 0.4 ppm when the dissolved hydrogen concentration (DH) in hydrogen water was measured with the portable dissolved hydrogen meter (Toa DKK Corporation).

    Since the present invention can efficiently adjust hydrogen water or carbonated water immediately before use, it can be expected to be useful for promoting human health as a drink or cosmetic. It is also useful as a calibration solution adjustment method for gas concentration analysis in water.
