Description

Filled product of hydrogen water, manufacturing method thereof, and manufacturing device thereof

The present invention relates to an article filled with hydrogen water in a can container and a method of manufacturing the same, and more particularly to a hydrogen self-hydrogen in an unopened state by making the hydrogen water after the sealing filling not contact with a gas other than hydrogen A novel filled product with minimal release of water and a method for its manufacture.

Based on the understanding of the effectiveness of maintaining health, the production and sales of hydrogen water have been formed and have received much attention. The reason for this is that hydrogen water participates in the so-called "Oxidative Stress" which removes the occurrence and deterioration of various diseases. Active oxygen, which is often produced in the living body, acts as part of the body's immune function. However, when the active oxygen is required to be more than necessary (this state is called "oxidative stress"), it may cause damage to itself. Since it is the main cause, it is considered that it is necessary to remove excess active oxygen on a daily basis. Further, although collectively referred to as "active oxygen", since there are various molecular forms, it is considered that there is no structure in which all molecular species of active oxygen are uniformly removed.

According to recent research results related to the structure of removing active oxygen, it is proposed that molecular hydrogen participates in the removal of one part of the "active oxygen" molecular species. Therefore, as a method of simply taking in molecular hydrogen, a person who continuously drinks hydrogen water is practiced. Increased. However, the functions and effects of the molecular hydrogen in the living body have not been clearly understood, and are currently in the stage of diligent research in various research institutions. Therefore, the mechanism is not described here.

With the increase in attention to this kind of hydrogen water, about hydrogen water production, development, and improvement There are various techniques, and specifically, the following methods can be exemplified.

(1) Electrolysis

(2) Pressurization and storage method

(3) Gas-liquid mixing nozzle method

(4) Nano microbubble method

(5) Gas-liquid separation hollow fiber membrane method

In any of the production methods, it is possible to produce hydrogen water having a high concentration of a saturated concentration (for example, a dissolved hydrogen concentration of 1.6 ppm at 25 ° C) or a saturation concentration, and is used for household or industrial use. The hydrogen water machine or the hydrogen water production device is sold.

Although there are so-called "water dispensers" that are also popular among ordinary households, the development of hydrogen water production technology, the "hydrogen machine" for household use in beverages is also manufactured and sold by a number of companies, and the above-mentioned health intentions are rising. Start to spread for the background. In the case of "hydrogen water machine" for household use, it is premised that "high-concentration hydrogen water" supplied from the supply machine is immediately consumed without time interval. Therefore, there are few points or problems in the preservation of hydrogen water.

On the other hand, as a method of simply drinking hydrogen water, it is also possible to use "hydrogen water filled in a sealed state in a container" (hereinafter referred to as "hydrogen water filled in a container"), and it is commercially available for this purpose. There are several classes. Here, the classification of the commercially available "hydrogen water filled into the container" can be roughly divided into

(1) PET bottle filling

(2) Aluminum bag filling

(3) aluminum bottle filling

These three categories, but regardless of the hydrogen water of any form, are referred to as their preservation There is a big problem.

That is, at the time of purchase, hydrogen water, that is, "hydrogen water filled into the container", has a significantly lower concentration of dissolved hydrogen or contains no hydrogen. In fact, the Internet has been uploaded with "filled at the time of purchase." The concentration of hydrogen water in the container is low or "no hydrogen" is written, and the problem of the preservation of hydrogen is becoming apparent.

Furthermore, this actual situation may be reflected. The current state of the art is that there are a large number of prior art documents on the manufacturing method of hydrogen water, but there are few prior art documents on the method of preserving hydrogen water (for example, refer to Patent Documents 1 and 2).

Further, the above Patent Documents 1 and 2 are frozen and stored immediately after the generation of hydrogen water, thereby suppressing the release of hydrogen. However, this method has a major disadvantage in that it takes a long time to melt the cryopreserved hydrogen water (for example, 12 hours at room temperature), and it is not immediately drinkable when it is desired to drink. Moreover, since it is necessary to freeze at the time of storage, not only the manufacturing cost is increased, but also refrigeration equipment is required for distribution or storage in each store, and there is a problem that the practical inconvenience cannot be completely eliminated.

The lid portion covers the can body portion of the can container, and the can lid portion is sealed to the can body portion to produce a filled product of hydrogen water; and the feature is: The hydrogen water filled in the can body is sealed and filled in a state in which the can lid portion is sealed in the sealed state of the can body portion without being in contact with a gas other than hydrogen.

Further, the method for producing a hydrogenated water-filled product according to claim 5 is characterized in that, in addition to the requirements of the fourth aspect, when the hydrogen water filled in the can body is not in contact with a gas other than hydrogen, the following occurs. Overflow of either or both, filling the hydrogen water into the metal can: overflowing the hydrogen water from the canister during the step of filling the hydrogen into the canister; The can lid portion is installed in a tank filled with a hydrogen water tank to overflow the overflow of hydrogen water from the tank body.

Further, the method for producing a filled product of hydrogen water according to claim 6 is characterized in that, in addition to the requirements of the fourth aspect or the fifth aspect, when the hydrogen water is filled into the can container, the filling of the hydrogen water is started. The injection is performed in a submerged state in which the discharge port of the water injection nozzle is located under the surface of the hydrogen water that has been injected into the tank container.

The above-mentioned problems are solved by the constitution of the inventions of the respective technical solutions.

That is, according to the inventions of claims 1, 4, and 7, the release of hydrogen from the sealed and filled hydrogen water can be suppressed during the period from the manufacture to the use of the user (for example, for drinking, for drinking). At a significantly lower ratio, the dissolved hydrogen concentration of the hydrogen water in the circulation process can be maintained at a higher level. Moreover, since the storage of the filled product of hydrogen water can be carried out at room temperature, there is no need to spend the time or time of thawing, and the user can drink immediately when he wants to drink. Moreover, since it is not stored in a frozen state, the circulation cost can be reduced. In this respect, the burden on the equipment can be reduced for the store, and the cost for storage can be suppressed (for example, storage in a warehouse or in a store display cabinet, etc. Freezing device). Further, in this regard, it is easy for the manufacturer, the distributor, the seller (retailer), the user, and the like to easily process the filled product, and the product form is improved in convenience or simplicity.

Further, according to the invention of claim 2, a specific method of bringing the hydrogen water which has not been filled into contact with a gas other than hydrogen is realized. That is, as a method of making the sealed-filled hydrogen water not in contact with a gas other than hydrogen, in addition to filling (filling with hydrogen water until the entire volume is filled without forming a head space in the tank), it is also possible to consider Hydrogen water is filled in a manner of providing a head space on the upper portion of the tank, and hydrogen gas is filled into the head space. However, since the hydrogen gas is extremely light, and there is a danger that the explosion limit is wide, it is not as long as, for example, nitrogen gas. The existing method of filling into the head space can be realized by changing the gas to hydrogen, and various difficulties can be expected in the actual manufacturing site. In this regard, it is believed that the implementation of filled fill is higher than the method of filling hydrogen into the headspace.

According to the invention of claim 3, since the concentration of dissolved hydrogen after the storage of the product of the present invention is maintained at 1 ppm or more, it is objectively confirmed that the method of preserving the filled product is appropriate (excellent).

Moreover, according to the invention of claim 5, the overflow of either or both of the primary overflow when the hydrogen water is filled and the secondary overflow when the can lid is installed can reliably inject the hydrogen water. Fully filled into the metal can body.

Further, according to the inventions of claims 6 and 8, the following filling method is obtained: when the hydrogen water is filled into the can container, the water injection nozzle is filled in the submerged state except at the start of filling, so that hydrogen water can be formed as much as possible It is not easy to contact with air, but inhibits the release of hydrogen. Furthermore, this submerged fill is The preferred conclusion is obtained by the inventors of the experiment on the difference in the amount of hydrogen dissolved by the difference in the filling position (filling speed is fixed). In addition, in this experiment, it was confirmed that when the discharge port of the water injection nozzle was set to a position higher than the upper end of the tank container (the state in which the nozzle discharge port was not submerged), the concentration of hydrogen water dissolved was lower than that of the submerged filling, and it was considered that The reason is that the dissolved hydrogen in the hydrogen escapes due to the entrapment of air during filling.

The best mode for carrying out the invention is as described in the following embodiments, and further includes various methods which can be modified within the technical idea thereof.

In addition, in the description, the research and investigation on the preservability of the generated hydrogen water will be described. In other words, the actual situation of the method of preserving the hydrogen water in the container (corresponding to the "filled product of hydrogen water 10" in this case) and how to store hydrogen water in a normal temperature environment can suppress hydrogen from hydrogen water. The basic technical idea of the present invention released is initially indicated. Then, the name of the can body and the hydrogen water at the time of manufacturing the filled product 10 will be described (defined), and then the manufacturing method of the filled product will be described while describing the manufacturing method.

Here, in the present specification, the hydrogen-filled water in the sealed filling state of the container (the tank container in the present invention) is referred to as "hydrogen-filled product 10", but there is also a case where it is simply referred to as "filled product 10". .

[Examples] [Research and investigation on the preservation of hydrogen water]

As a first step in grasping the problem of the preservation of hydrogen water in the present state, the inventors first measured the commercially available "filled into the container" over time (here, about once every month, and after 6 months). The concentration of hydrogen water. Show the results obtained In Figure 5. Here, the products of each company of A~K use the same batch of goods (products manufactured under the same conditions). Moreover, the "hydrogen water filled in the container" purchased as a sample is

(1) PET bottle filling

(2) Aluminum bag filling

(3) aluminum bottle filling

In the case of the third type, (1) the product of the PET bottle type has a dissolved hydrogen concentration of "0 (zero)" (for example, other company products H, K, etc.), and cannot be measured with time.

In addition, in other products of the company, A~K, although the concentration of dissolved hydrogen is significantly lower after purchase, it can be confirmed that (2) aluminum bag filling, (3) aluminum bottle filling hydrogen concentration is elapsed. In the case where the amount of land is reduced and it is reduced to about half of the initial concentration after three months, it is known that (2) aluminum bags and (3) aluminum bottles cannot store "hydrogen water" for a long period of time. In addition, the measurement of the dissolved hydrogen concentration was carried out using a dissolved hydrogen apparatus "DH-35A" manufactured by East Asia DKK Co., Ltd.

In addition, in the result of FIG. 5, the value (the dissolved hydrogen concentration) exceeding the initial measurement concentration at the time of one month or the time exceeding the one month after the lapse of one month is used for each measurement. At the same time, the product in the closed state is opened, so although it is actually the same manufacturer and product at the time of one month and the initial measurement point, it is measured as a different sample (individual) (even after the bolt is opened once again) It is also easy for hydrogen to escape due to air contact, so it is not possible to measure with the same sample. That is, although the dissolved hydrogen concentration in the data rises, it does not actually rise, because the sample error (individual difference) generated in the same product originally exists, and the whole is tilted. As shown in Fig. 5, it is necessary to observe the data measured over a long period of time, for example, about 6 months.

Next, in order to understand the factors affecting the preservability of hydrogen water, two containers of the area in contact with the air were filled with hydrogen water, and it was measured how the concentration of dissolved hydrogen changes with time. The results obtained are shown in Fig. 6. As can be seen from the graph of Fig. 6, the decrease in the dissolved hydrogen concentration in the area where the contact with air is large is large, and if it is 2 hours (120 minutes) in the experiment, it is reduced to 1/4 or less of the initial concentration. From this result, it can be seen that if "hydrogen water" comes into contact with air, hydrogen will escape from "hydrogen water", so that it is extremely effective to block contact with air when storing "hydrogen water" filled in the container. in conclusion.

Secondly, the following verification is carried out: when the hydrogen water filled into the PET bottle is not in contact with the air, in particular, in such a manner as to prevent air from entering the PET bottle (in a manner that does not generate a head space) In the case of "hydrogen water", can you save "hydrogen water"? The results obtained are shown in Fig. 7. As can be seen from the figure, even if the PET bottle is filled with hydrogen-filled water, if it passes for 10 hours, it will be reduced to one-half of the initial dissolved hydrogen concentration. Of course, it is also known that the dissolved hydrogen concentration of the person who has the head space is further lowered than that of the filled filler.

In view of the reduction in the concentration of dissolved hydrogen in hydrogen water in PET bottles, it is considered to be related to the "breathability" of synthetic resins. For example, according to the literature for comparing the gas permeability of rubber, hydrogen exhibits a gas permeability of about 5 times that of nitrogen, and is also about 2 times higher than that of oxygen.

Hydrogen (MW=2) 1.4

氦(MW=4) 1.0

Oxygen (MW=32) 0.8

Nitrogen (MW=28) 0.3

Although accurate comparative data cannot be obtained, it is known from various documents that the PET bottle also has gas permeability similarly to rubber, and it is particularly known that the gas permeability of hydrogen which is the smallest molecule is stronger than other gas types. Therefore, it can be considered that even if the PET bottle is filled with hydrogen-filled water, the dissolved hydrogen concentration is reduced within a few hours.

In addition, even in the case of an aluminum cap bottle which is a completely sealed metal enamel which does not allow hydrogen to permeate, the concentration of dissolved hydrogen is reduced, and as a result, it is considered that in the case of the aluminum cap bottle, The gasket made of synthetic resin or tantalum on the inner side of the top cover is sealed (so that the hydrogen water does not leak out), so that hydrogen contained in the hydrogen water permeates through the gasket to the outside of the bottle.

Considering the main factors related to the preservability of hydrogen water as described above, it was concluded that the method of using all of the following three items in the preservation of hydrogen water was effective, thereby achieving the present invention.

(A) A metal can (which may be either steel or aluminum) which is a material that does not permeate hydrogen.

(B) Hydrogen water is not brought into contact with a gas other than hydrogen such as air, particularly in a sealed and filled state.

(C) When the can is sealed by a gasket, the amount of the synthetic resin having gas permeability is reduced as much as possible.

As a result, in the present invention, for example, hydrogen water is filled and filled into the metal can, for example, without generating a head space, and the hydrogen water after the sealing filling is not brought into contact with a gas other than hydrogen. That is, the present invention is by satisfying the above-mentioned (A) to (C) The filled article 10 is manufactured by the method of the article to suppress the decrease in the dissolved hydrogen concentration of the hydrogen water.

Next, the name of the filled product 10 and the can body when the filled product 10 is manufactured will be described.

In the following description, for example, as shown in Fig. 2(a), the hydrogen water W after the formation is filled and filled into the can container, so that the filled product 10 in which the head space 14 is not generated in the can (upper portion) is provided. For example, when the hydrogen water W after the seal filling is not in contact with a gas other than hydrogen, it is not necessarily only filled in such a filling, and may be, for example, as shown in Fig. 2(b), in the tank (upper part Set the headspace 14 and fill it with hydrogen.

Here, as an example, it is assumed that the pull ring does not enter the full open end of the contents (hydrogen water W) when the can lid is opened as shown in FIG. 2, but may be an open plug. The pull ring enters the SOT (Stay-On Tab) tank in the contents.

The filled product 10 is a can body in which the hydrogen water is filled in the can container 10A, and the lid is covered to block the hydrogen water from the outside. Here, the symbols "11" and "12" are attached to the tank main body portion and the can lid portion, and the rising portion from the opening surface of the can lid portion 12 to the upper end portion of the can body portion 11 is referred to as "rising". Part 13". Further, as shown in Fig. 2(b) above, in the present invention, the case where the tank is not filled with the hydrogen-filled water W may be referred to, and this portion is referred to as the head space 14 in the present specification.

In addition, the tank container 10A is shown in a state in which the tank body portion 11 has a bottomed cylindrical shape of the tank bottom (bottom lid) (that is, a state in which the tank lid portion 12 is not attached), and when the tank container 10A is obtained, The can body portion 11 and the can are pulled by drawing The bottom portion is integrally formed (so-called two-piece can), and the can body portion 11 and the can bottom can be separately formed and joined (so-called three-piece can).

Further, as the use of the hydrogen water W, it is mainly estimated to be used for beverages. In the case of beverages, once the plug is opened, hydrogen will escape from the hydrogen water W as time passes, so that no time is required after the opening of the plug. Drinking is a prerequisite. Moreover, the capacity of the tank filled with hydrogen water W is also mainly estimated to be a relatively small capacity of about 100 to 350 ml (so-called "one-time drinking type"). However, the use of hydrogen water is of course not limited to drinking, and it is also estimated to be used for, for example, cosmetics and lotions, and industrial use may be considered in the future. Therefore, the capacity is not limited to the above-mentioned "one-time-drinking type", and a so-called barrel-type can or drum-type can of a large capacity can be estimated as a can body. In this case, the can lid portion 12 is melted in the case. In the case of the can body portion 11, not only the winding can be considered, but also the fastening by a fastening metal member or by welding.

Further, according to the above, the filled product 10 (tank) is generally cylindrical in shape if it is drunk, but is not limited thereto.

In addition, the hydrogen water W is preferably dissolved in raw water such as distilled water, and it is preferable to dissolve hydrogen as much as possible until a high concentration, that is, a saturated concentration or a near saturation concentration. Further, as the raw water, applications such as tap water may be considered in addition to the above distilled water.

Further, in the method for producing hydrogen water W, various methods exist as described above, and any of them can generate hydrogen water W having a high concentration close to a saturated concentration. However, even if it is intentionally generated as a high-concentration hydrogen water W, the dissolved hydrogen concentration of the hydrogen water W is changed according to how the filling method itself fills the can container 10A. Therefore, the preferred method of filling is explained below. point).

As described above, there are many products in which the hydrogen storage concentration of commercially available hydrogen water is about 0.1 to 1.0 ppm. However, when it is filled in a container having a low preservability of hydrogen, even if the concentration of dissolved hydrogen in the state in which the lid is sealed is lowered over time, the function as hydrogen water is remarkably lowered. Moreover, since hydrogen has a property of easily escaping from water, it is meaningless if hydrogen is released during filling regardless of the high concentration of hydrogen water produced.

Therefore, in the present embodiment, when the hydrogen water W is filled into the can container 10A, the contact time and the contact area with other gases are reduced, and the filling speed and the water injection of the canister 10A and the hydrogen water W at the time of filling are taken into consideration. The positional relationship of the nozzles 31n. Further, although the hydrogen water W is in contact with other gases during the filling, the hydrogen water W that has come into contact with the canister 10A can be filled with water (filled), and the hydrogen water W can be filled at a higher concentration. seal.

Hereinafter, a device for manufacturing such a filled product 10 (hereinafter referred to as "manufacturing device 1 for filled products") will be described, and a manufacturing method will be described.

As an example of the manufacturing apparatus 1 of a filled product, as shown in FIG. 1, it consists of a hydrogen-hydrogen generating apparatus 2 which melt|dissolves hydrogen, and is contained in raw water until a desired density|concentration, and the hydrogen-water filling apparatus 3 The generated hydrogen water W is filled (injected) into the can container 10A; and the can lid sealing device 4 is melted (mounted) on the can lid portion 12 (the can body portion 11).

Here, when the hydrogen water W is obtained, various methods are employed as described above, and any of them may be employed. Therefore, the hydrogen water generating device 2 is omitted in the following description, and the hydrogen water filling device 3 and the can lid sealing device 4 will be described.

As an example, the hydrogen water filling device 3 is as shown in FIG. 1 and includes a filling machine body 31 which is produced by the hydrogen water generating device 2 of the preceding stage. The hydrogen water W is injected into the tank container 10A; the pump 32 is used to transfer the hydrogen water W to the filling machine body 31; the cleaning device 33 such as a filter for purifying the hydrogen water W; and the sterilizing device 34 ( For example, a UV (ultraviolet) sterilizing device for sterilizing hydrogen water W. Of course, the can container 10A used in the filling step is a bottomed cylindrical shape in which the hydrogen can water W as a content can be injected.

Further, the filling machine body 31 includes a water injection nozzle 31n for injecting hydrogen water W into the can container 10A, and in the present embodiment, the water injection nozzle 31n is configured to be movable up and down.

Further, in the present embodiment, when the hydrogen water W is filled into the can container 10A, and when the can lid portion 12 is covered with the can container portion 10A (the can body portion 11) after filling, either or both The hydrogen water W filled in the tank container 10A is overflowed and filled with the hydrogen water W. Therefore, it is preferable to provide a drain such as a drain pipe in the mounting table portion in which the tank container 10A is placed in the filling machine body 31. In the case where the overflow is different, the overflow of the hydrogen water W from the tank container 10A is referred to as an overflow at the time of filling, and the hydrogen water W is supplied from the tank container 10A when the can lid portion 12 is attached. The overflow is called secondary overflow.

Next, an example of an injection state when the hydrogen water W is filled into the can container 10A and an effect thereof will be described.

When the hydrogen water W is filled into the tank container 10A, the discharge port of the water injection nozzle 31n is placed in a submerged state under the water surface of the hydrogen water W that has been injected into the tank container 10A, except for the start of the filling of the hydrogen water W. The filling (so-called submerged filling) is performed in the state of the injected hydrogen water W. Therefore, the water injection nozzle 31n is formed to be movable up and down.

That is, as an operation of the actual water injection nozzle 31n, for example, as shown in Figs. 3(a) and 3(b), first, the water injection nozzle 31n is lowered to the vicinity of the bottom of the can container 10A (the distance between the nozzle discharge port and the bottom of the can at this time) It is determined according to the filling speed and the like, and is determined in consideration of the splash from the bottom of the tank, and the filling of the hydrogen water W is started in this state. Thereafter, as shown in FIG. 3(c) and FIG. 4(a), it is preferable that the discharge port of the water injection nozzle 31n is immersed in the hydrogen water W that has been injected into the tank container 10A.

In addition, as shown in the figure, the water injection nozzle 31n (discharge port) is gradually raised as the filling progresses, and at this time, for example, the liquid surface and the nozzle of the hydrogen water W injected into the tank container 10A can be made. The water injection nozzle 31n is gradually raised in such a manner that the distance of the discharge port is maintained constant.

In addition, when the mounting table in which the can container 10A is placed during the filling is moved up and down, the same operation as described above can be realized by moving the mounting table up and down. Therefore, in this case, it is not necessary to configure the water injection nozzle 31n to be movable up and down. In other words, the lifting operation of the water injection nozzle 31n may be performed relatively with respect to the mounting table on which the can container 10A is placed during filling.

Further, by adopting such an injection state (submerged filling), it is possible to suppress the impact of the hydrogen water W injected into the can container 10A during filling or the contact with air or other gas, and it is possible to prevent hydrogen from escaping from the hydrogen water. Out.

Further, the inventors of the present invention performed the above-described flooding filling and the position where the water injection nozzle 31n (discharge port) is disposed at a position higher than the upper end of the tank container 10A (tank main body portion 11) (that is, the nozzle discharge port is not filled during the filling process). The test, which was submerged in the non-submerged filling of the hydrogen water W, was compared, and it was confirmed that the amount of hydrogen released by flooding was small. It is believed that the nozzle outlet is always in the non-submerged filling It is set at a position higher than the upper end of the canister 10A, and is filled while tapping the water surface from the high position. Therefore, hydrogen is escaping from the hydrogen water W while the hydrogen water W is being entangled in the filling, so that the submerged filling is used in this embodiment. .

Further, the inventors have also conducted an experiment to investigate the influence of the difference in filling speed on the change in the concentration of hydrogen dissolved. In this experiment, as an example, the filling speed of 2 liters / 1 minute was compared with the speed of the filling speed of 1 liter / 1 minute. As a result, it was found that although there was no significant difference caused by the difference in the filling speed, The low speed of 1 liter / 1 minute has a tendency to maintain a high concentration slightly.

Next, the can lid sealing device 4 will be described. The can lid sealing device 4 is a device that covers the can lid portion 12 to the filled can container 10A (can body portion 11) and is sealed (sealed), in other words, the can is sealed and filled (here) In order to fill the internal hydrogen water W and the external space blocking device, the double sealing method used when the can is covered is used here. Therefore, the can lid sealing device 4 in this embodiment is essentially a can sealing machine 41. In addition, the double-wrap method refers to a method of crimping and joining the can lid portion 12 (circumferentially curled portion) into the flange portion of the can body portion 11 (upper edge).

Further, in the case of the sealing of the can lid portion 12, as shown in Figs. 4(b) and 4(c), it is preferable that the upper end of the can container 10A (the can body portion 11) filled with the hydrogen water W is provided. When the can lid portion 12 is placed on the edge (when the can lid portion 12 is covered), the hydrogen water W overflows from the canister 10A (the above-described secondary overflow), and in this state, that is, at the upper portion of the can body The can lid portion 12 is sealed in the state in which the head space 14 is present.

Moreover, therefore, it is preferred to support the tank capacity directly or indirectly in the can sealing machine 41. In the base portion of the tank 10A (tank), a drain device such as a drain pipe for allowing secondary overflow is provided in the same manner as the hydrogen water filling device 3.

The manufacturing apparatus 1 for a filled product of the present invention is configured as described above, and a preferred embodiment of the can body in the actual use of the filled product 10 (tank) will be described below (for example, in the case of filling with filling), the above-described drawing is preferred. 2) Full Open End).

When filling with a content having a low viscosity such as mineral water, there is a case where a part of the content is splashed when the plug is opened. For example, in a SOT can (indwelling pull-type can), the pull ring enters the contents when the plug is opened, and as a result, the contents are extruded to become a spatter-like splash to the outside, and the surrounding is wet. Especially in SOT cans, considering that in most cases, the user (drinker) holds the can with one hand, and uses the other hand to perform the opening operation of the pull ring, while holding the can body in an unstable state, the content is more Easy to fly.

Moreover, it can be estimated that the scattering of such contents at the time of opening the plug may cause dissatisfaction to the consumer. As means for solving this problem, it is considered to be a fully open cover in which the tab does not enter the contents as shown in Fig. 2 described above. In addition, it is considered that in the case of the full-opening method, in many cases, the can is placed on a table or a table in a stable state after the opening, and then the opening operation is performed, so that the contents can be further prevented from scattering to the surroundings.

Furthermore, in the case where the filling product 10 shown in FIG. 2(b), that is, the tank body (upper portion) is provided with the head space 14 and the hydrogen gas is filled thereto, the full opening cover can be more reliably performed, and the SOT tank can be more reliably performed. The content is scattered during the opening (prevention of spillage).

Also, it is considered that the filling of the filled product 10 will cause the following questions. Problem: If the height of the "rising portion 13" shown in Fig. 2 is low, the liquid level of the hydrogen water W at the time of opening the plug becomes substantially the same height as the upper end of the tank main body portion 11 (the edge of the can), and drinking first In order to prevent the hydrogen water W from being spilled, it is necessary to move the stuffed product 10 that has been opened to the mouth in a horizontal state, so that drinking is difficult.

As a means for solving the problem, as long as the size of the rising portion 13 is about 5 to 10 mm, it acts as a sputum, and the drinking difficulty when drinking the first mouth can be eliminated, and the contents can be prevented from being opened at the time of opening the plug. Flying around.

Next, the effectiveness of the preservability of the filled product 10 (the present invention) produced by the production method of the present invention will be described.

First, the distilled water (hydrogen water W) having a dissolved hydrogen concentration of 1.4 ppm is filled by a microbubble method and filled into a steel SOT tank (retained pull-ring type tank) for 200 ml, and then used at intervals. The sealing machine manufactured by Toyo Can Co., Ltd. is double-sealed.

The filled hydrogen water W was stored in a thermostat at 37 ° C (assumed to be summer), and two of the cans were taken out every one week to measure the dissolved hydrogen concentration. In addition, the measurement of the dissolved hydrogen concentration was carried out using a dissolved hydrogen apparatus "DH-35A" manufactured by East Asia DKK Co., Ltd.

The results obtained are shown in Fig. 8. According to the graph, almost no decrease in the dissolved hydrogen concentration was observed, and even after 6 months (180 days), the dissolved hydrogen concentration showed a value of 1.0 ppm or more.

Further, based on the measurement results, the following linear regression equation was obtained, and the fluctuation of the hydrogen concentration during the period of 6 months was calculated by a statistical method.

y=-0.001x+1.2528 (y: hydrogen concentration, x: days of storage)

From the regression equation, it can be seen that when the initial value is 1.25 ppm, the estimated hydrogen concentration after 6 months is 1.07 ppm, and the reduction rate of hydrogen concentration after storage for 6 months is limited to about 14%. When the hydrogen concentration at the time of filling is 1.25 ppm or more, the hydrogen water W can be stored in a state of maintaining a high concentration of hydrogen of 1 ppm or more even in the summer, and the invention of the present invention can be confirmed as hydrogen water W. The preservation method is excellent.

On the other hand, Fig. 5 above shows the results of measuring the dissolved hydrogen concentration of other company products stored at room temperature as described above for about one month and for six months. The product having a dissolved hydrogen concentration of 1 ppm or more at the start of the measurement has only two types among the 11 varieties, and objectively indicates the difficulty of filling the container in a state in which the dissolved hydrogen concentration is maintained at a high concentration, and indicates that even Products with a high concentration of 1 ppm or more are reduced to about 0.7 to 0.8 ppm after 3 months of storage (well below 1 ppm). When the linear regression formula of each of the two products (the above two types) is obtained in the same manner as the product of the present invention, and the hydrogen concentration reduction rate of the two products after three months of storage is calculated by a statistical method, It is 29~37%, and the hydrogen concentration reduction rate is 59~75% when it is stored for 6 months. From this point, as described above, the reduction rate of the hydrogen concentration at the time of storage of the present invention for 6 months is about 14%, and the present invention can suppress the decrease in hydrogen concentration to 1/4 to 1 as compared with other company products. /5, this point is the excellent effect of the invention.

Further, in the case of a low concentration of hydrogen water having an initial hydrogen concentration of 0.4 ppm or less, the rate of decrease in the concentration of hydrogen during the storage period tends to be small, and the rate of decrease in the concentration of hydrogen during the comparative storage period can be determined. In the case of the case, it is important to compare the hydrogen water having a high concentration of 1 ppm or more.
