Description

[Technical field]

[0001] The present invention relates to a hydrogen-containing water product for drinking by pets, and more particularly to a hydrogen-containing water product for drinking by pets, which is filled with hydrogen-containing water having low concentrations of calcium ions and magnesium ions. [Background technology]

[0002] In recent years, hydrogen-containing water (also simply called hydrogen water), which is water in which hydrogen gas has been dissolved, has attracted attention as it is said to have the effect of inhibiting the oxidation of metals and the spoilage of food due to its high reducing properties.It is also expected to improve various health disorders if it is converted into drinking water.

[0003] For example, hydrogen-containing water for drinking can be produced by dissolving hydrogen gas from a gas cylinder in raw water, or by dissolving hydrogen gas generated by electrolysis of water in raw water (for example, Patent Document 1). As hydrogen-containing water with a higher concentration of dissolved hydrogen, for example, a method has been proposed in which hydrogen gas is filled in a pressure vessel from which air has been removed, and while maintaining the pressure of the hydrogen gas in the pressure vessel at 2 to 10 atmospheres, raw water is sprayed in a shower-like manner into the pressure vessel to contact the hydrogen gas, thereby efficiently dissolving the hydrogen gas and obtaining hydrogen water (Patent Document 2). In addition, a method has been proposed in which hydrogen gas is sprayed into water at high pressure to generate ultrafine bubbles (so-called "nanobubbles" and "microbubbles"), which are then dissolved in water to produce hydrogen-containing water (Patent Document 3). The hydrogen-containing water is commercially available in a form filled, for example, in beverage cans with stay-on tabs, bottle-shaped beverage cans, or containers with spouts (containers with straws) called cheer packs.

[0005] Conventional hydrogen-containing water for drinking, in which hydrogen is dissolved in raw water, contains minerals (mineral ions) such as calcium ions and magnesium ions contained in the raw water. Although minerals are essential nutrients for humans, animals' bodies can have difficulty metabolizing minerals like humans do, and excessive intake can lead to illness and stress. Cats and dogs in particular have narrow blood vessels in their kidneys, and the risk of kidney disease increases with age, so there is concern that even the calcium and magnesium ion levels contained in tap water can place a heavy burden on the kidneys of cats and dogs.

[0006] When giving hydrogen-containing water to pets such as dogs and cats, it is common to give it in a relatively flat pet dish such as a food bowl or water bowl. However, when the hydrogen-containing water is transferred to such a dish, the contact surface between the hydrogen-containing water and the air is large, so hydrogen evaporates over time and the dissolved hydrogen concentration decreases. Although there is no problem if the hydrogen-containing water is transferred to the dish and consumed immediately, it is not very desirable to leave the hydrogen-containing water in the dish from the perspective of the decrease in dissolved hydrogen concentration. In addition, if the hydrogen-containing water is poured into the dish vigorously, the contact surface with the air increases, which also leads to a decrease in the dissolved hydrogen concentration, and there is also a risk that the water will overflow from the dish due to excessive force, so it is preferable to pour the hydrogen-containing water gently and with controlled flow. For pets that cannot drink on their own, hydrogen-containing water can be poured into a syringe and given to them. In some cases, this may be done. In order to maintain the dissolved hydrogen concentration as much as possible, it is desirable to allow dogs and cats to drink hydrogen-containing water filled in the above-mentioned beverage can or container with a spout directly from the can or container. However, it is difficult for pets to directly ingest liquid from the above-mentioned beverage can due to their skeletal structure, and even if the owner tries to feed it to the pet by tilting the can, there are difficulties such as the liquid spilling out of the can. In addition, in the case of the above-mentioned container with a spout, if the owner tries to help the pet by pushing the container, the excess liquid will go directly into the pet's mouth, which may cause aspiration, and if the pet tries to ingest it directly, the suction power may be insufficient and the pet may not be able to drink it.

[0007] The present invention aims to provide a hydrogen-containing water product that can provide hydrogen-containing water to pets without excessive amounts spilling out of the container even when an owner presses the container when trying to give the pet hydrogen-containing water directly from the product, and to provide a hydrogen-containing water product filled with drinking hydrogen-containing water for pets that has a reduced content of minerals such as calcium ions and magnesium ions. [Means for solving the problem]

[0008] That is, the present invention is directed to the following aspects [1] to [3]. [1] A hydrogen-containing water product for drinking for pets, comprising a spout-equipped packaging container including a flexible bag-shaped container body, a spout inserted into the container body, and a cap for the spout screwed onto the top of the container body, the spout being filled with hydrogen-containing water, The spout-equipped packaging container has a spout attached to the upper part of a bag-shaped container body by heat sealing, and the shape of the seal lower edge of the heat-sealed part at the upper part of the container body is a trapezoidal wave shape having a valley part, a crest part and a valley part in this order and a ridge part connected to the valley part and the crest part, and the seal lower edge intersects with the left edge of the container body and the seal edge intersects with the right edge of the container body at approximately right angles, The hydrogen-containing water is pH is 6.2 to 6.8, The calcium ion concentration and magnesium ion concentration are less than 0.01 ppm, The redox potential is -500 mV or less. The dissolved hydrogen concentration is 0.8 ppm or more. This relates to hydrogen-containing water products. [2] The hydrogen-containing drinking water product for pets described in [1], wherein the product capacity of the container body is 150 mL to 550 mL. [3] A boxed kit for the hydrogen-containing water product for drinking for pets according to [1] or [2], A boxed kit, characterized in that the container body is loaded into the box in a horizontal position that is maintained approximately horizontally. Effect of the Invention

[0009] The hydrogen-containing water product for drinking pets of the present invention can provide a hydrogen-containing water product that allows pets to give hydrogen-containing water without an excessive amount spilling out of the container when an owner tries to give hydrogen-containing water to a pet by, for example, pushing the container. Even when hydrogen-containing water is transferred to a pet dish or a syringe to be given to a pet, the hydrogen-containing water product for drinking pets of the present invention can prevent an excessive amount from spilling out of the product's container, and can prevent water from overflowing from the dish when poured too forcefully, allowing the desired amount to be poured into the pet dish or syringe. Furthermore, the hydrogen-containing water product for drinking pets of the present invention not only allows the desired amount of hydrogen-containing water to be poured out, but also allows the air to be pushed out and expelled by, for example, pushing the container, even if air gets into the container. Therefore, even when the hydrogen-containing water product for drinking for pets cannot be consumed in one go, i.e., when the product is opened once and the hydrogen-containing water is given to the pet, and then the lid (cap) is closed again to store the remaining hydrogen-containing water, the air that has entered the container can be pushed out and discharged, thereby suppressing contact between the hydrogen-containing water and the air that may remain inside the container during storage, and a hydrogen-containing water product can be provided that can be stored without decreasing the dissolved hydrogen concentration. The hydrogen-containing water product for drinking for pets according to the present invention is filled with hydrogen-containing water having a dissolved hydrogen concentration of 0.8 ppm or more, a calcium ion concentration and a magnesium ion concentration both less than 0.01 ppm, and a nearly neutral pH of 6.2 to 6.8. That is, according to the present invention, a hydrogen-containing water product filled with hydrogen-containing water having a reduced content of minerals such as calcium and magnesium can be provided as a hydrogen-containing water product for drinking for pets, particularly dogs and cats, who are at risk of kidney disease. Furthermore, the boxed kit of the present invention allows the hydrogen-containing water product for pets to be stored without decreasing its dissolved hydrogen concentration by loading it sideways into a box, thereby making it possible to provide a hydrogen-containing water product that maintains a high dissolved hydrogen concentration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The present invention will now be described in more detail with reference to the drawings. Fig. 1 is a perspective view of a hydrogen-containing water product 1 of the present invention. Fig. 5 and Fig. 6 are perspective views of a boxed kit 10 of the present invention.

[0012] Example 1. Hydrogen-containing drinking water product for pets The hydrogen-containing water product for drinking by pets according to the present invention comprises a spouted packaging container comprising a flexible bag-shaped container body, a spout inserted into the container body, and a cap for the spout screwed onto the top of the container body, the interior of which is filled with hydrogen-containing water. As shown in Fig. 1, the hydrogen-containing water product 1 for drinking for pets according to the present invention is in a form in which hydrogen-containing water 6 is filled inside a spouted packaging container 5 consisting of a container body 2, a spout 3, and a cap 4, and then an opening 3a of the spout 3 is sealed with the cap 4. The spouted packaging container 5 is formed by attaching the spout 3 to the upper part of a bag-shaped container body 2 by heat sealing, and is characterized in that the shape of the lower edge of the heat-sealed part on the upper part of the container body 2 has a trapezoidal wave shape having a valley part, a peak part, and a valley part in this order, and a ridge part connected to the valley part and the peak part.

[0013] In the spout-equipped packaging container 5, a container body made of aluminum laminate film, for example, a pouch container in the form of a so-called "aluminum pouch", is preferably used as the container body 2 because it has high airtightness and can prevent hydrogen from leaking out. As for the shape of the pouch container, various types such as a gusset type (with gusset) and a stand type (without gusset) that are already commercially available can be used. Furthermore, as the spout 3, a barrier spout manufactured using a barrier material can be used.

[0014] As an example of a packaging container with a spout, a gusset-type (horizontal gusset type) packaging container having gussets on the left and right (sides) of a bag-shaped container body is shown in Figure 2, a stand-type (bottom gusset type) packaging container having a gusset at the bottom of a bag-shaped container body is shown in Figure 3, and an example of a spout used in this invention is shown in Figure 4.

[0015] As shown in Figure 2, the gusset-type spouted packaging container 1 becomes box-shaped (rectangular) when filled with the content (hydrogen-containing water) (Figure 2(b)). This packaging container is composed of a container body 2 made by thermally welding an aluminum laminate sheet into a bag shape, and a resin spout 3. Although omitted in Figure 2, a resin cap is attached to seal the opening 3a of the spout 3. As shown in FIG. 2(b), the container body 2 is composed of a front sheet 21a on the front side as viewed from the front, a back sheet 21b on the back side thereof, and a right side sheet 21c and a left side sheet 21d folded in two and sandwiched between these two sheets. The container body 2 is formed into a bag shape having a bottom 22 and a gusset 23 by heat-sealing the right edge of the front sheet 21a and the front edge (left edge) of the right sheet 21c, the rear edge (right edge) of the right sheet 21c and the right edge of the back sheet 21b (left edge when the back sheet is viewed from the front), the left edge of the back sheet 21b (right edge when the back sheet is viewed from the front) and the rear edge (left edge) of the left sheet 21d, and the front edge of the left sheet 21d (right edge) and the left edge of the front sheet 21a. The spout 3 is attached by being inserted between the front sheet 21a and the back sheet 21b and heat-sealed to the approximate center of the upper edges of both sheets. From the heat-sealed portion 24a between the spout 3 and the front sheet 21a to the heat-sealed right or left edge of the front sheet 21a below the heat-sealed portion 24a, the upper edge of the front sheet 21a is heat-sealed to the upper edge of the right sheet 21c or the upper edge of the left sheet 21d. Also, from the heat-sealed portion 24b between the spout 3 and the back sheet 21b to the heat-sealed right or left edge of the back sheet 21b below the heat-sealed portion 24b, the upper edge of the back sheet 21b is heat-sealed to the upper edge of the right sheet 21c or the upper edge of the left sheet 21b, respectively, to form an upper edge heat-sealed portion 7 (see FIG. 2(a)). As shown in FIG. 2(b), the heat-sealed portions of the upper edges of the front sheet 21a and the right side sheet 21c and the heat-sealed portions of the upper edges of the back sheet 21b and the right side sheet 21c may be overlapped and fixed by welding; similarly, the heat-sealed portions of the upper edges of the front sheet 21a and the left side sheet 21d and the heat-sealed portions of the upper edges of the back sheet 21b and the left side sheet 21d may be overlapped and fixed by welding. The seal lower edge 71 of the upper edge heat seal portion 7, i.e., the seal lower edge 71 consisting of the seal edge extending from the seal edge of the heat seal portion 24a between the spout 3 and the front sheet 21a to the right edge seal portion of the front sheet 21a and the seal edge extending to the left edge seal portion of the front sheet 21a, and the seal lower edge 71 consisting of the seal edge extending from the seal edge of the heat seal portion 24b between the spout 3 and the back sheet 21b to the right edge seal portion of the back sheet 21b and the seal edge extending to the left edge seal portion of the back sheet 21b, are formed of valley portions (71a) and peak portions (71b). The seal has a trapezoidal wave shape having a valley portion (71c), a peak portion (71a), a valley portion (71b), and a ridge portion (71d, 71e: oblique side shape) connected to the peak portion (71b) and the valley portion (71c) (in FIG. 2(a) , the seal lower edge 71 is shown in bold for emphasis).

[0016] As shown in FIG. 3, in the stand-type spout-equipped packaging container 1, the container body 2 is composed of a front sheet 21a, a back sheet 21b, and a bottom sheet 21e that is folded in two and sandwiched between these two sheets. The container body 2 is formed into a bag shape having a bottom 22 by heat-sealing the right edge of the front sheet 21a to the right edge of the back sheet 21b (the left edge when the back sheet is viewed from the front), the left edge of the front sheet 21a to the left edge of the back sheet 21b (the right edge when the back sheet is viewed from the front), the lower edge of the front sheet 21a to the front edge of the bottom sheet 21e, and the lower edge of the back sheet 21b to the rear edge of the bottom sheet 21e. The spout 3 is attached by being inserted between the front sheet 21a and the back sheet 21b and heat-sealed to the approximate center of the upper edges of both sheets. The upper edge of the front sheet 21a and the upper edge of the back sheet 21b are heat-sealed from the heat-sealed portion 214 between the spout 3 and the front sheet 21a and the back sheet 21b to the heat-sealed right edge or left edge of the front sheet 21a and the back sheet 21b below the heat-sealed portion, respectively, to form an upper edge heat-sealed portion 7 (see Figure 3(a)). The lower seal edge 71 of the upper edge heat seal portion 7, i.e., the lower seal edge 71 consisting of the seal edge extending from the seal edge of the heat seal portion 24a between the spout 3 and the front sheet 21a to the right edge seal portion of the front sheet 21a and the left edge seal portion of the front sheet 21a, and the lower seal edge 71 consisting of the seal edge extending from the seal edge of the heat seal portion 24a between the spout 3 and the back sheet 21b to the right edge seal portion of the back sheet 21b and the left edge seal portion of the back sheet 21b, has a valley portion (71a), a peak portion (71b) and a valley portion (71c), and has a trapezoidal wave shape having ridge portions (71d, 71e: oblique side shapes) connected to the valley portion (71a) and the peak portion (71b) and the peak portion (71b) and the valley portion (71c) (in Figure 3(a) the lower seal edge 71 is shown in bold for emphasis).

[0017] 2(a) and 3(a), the seal lower edge 71 has a valley portion 71a, a crest portion 71b, and a valley portion 71c, and also has ridge portions (71d, 71e: oblique side shapes) continuing to the valley portion 71a, the crest portion 71b, and the crest portion 71b and the valley portion 71c, and has a trapezoidal wave shape in which the valley portion 71a, the crest portion 71b, and the valley portion 71c are approximately parallel. In this trapezoidal shape, the seal lower edge 71 intersects with the left edge or the right edge of the container body 2 at approximately a right angle (α in FIGS. 2(a) and 3(a)). In this way, by having the seal lower edge 71 have the trapezoidal wave shape as described above, when an owner tries to give hydrogen-containing water filled in the container body to a pet and presses the side of the container body to discharge the hydrogen-containing water, which is the content, the flow (flow) of the hydrogen-containing water in the container body 2 is moderately restricted, and the flow of the hydrogen-containing water into the spout is moderately restricted, so that an excessive amount of liquid does not overflow from the container and it is possible to prevent the pet from swallowing it. In addition, due to the trapezoidal shape, when the product that has been opened is recapped and stored, the air that has entered the inside of the container body 2 can be easily discharged by pressing the side of the container body, thereby reducing the amount of air remaining inside the container body and suppressing a decrease in the dissolved hydrogen concentration due to contact between the hydrogen-containing water and the air. As shown in these figures, the valley portion (71a), the peak portion (71b), the valley portion (71c), the ridge portion (71d) connecting the valley portion (71a) and the peak portion (71b), and the ridge portion (71d) connecting the peak portion (71b) and the valley portion (71c) are in a shape of a combination of straight lines. In addition, the connecting portion between the valley portion (71a) or the peak portion (71b) and the ridge portion (71d), and the connecting portion between the peak portion (71b) or the valley portion (71c) and the ridge portion (71e) intersect at an acute angle (obtuse angle) as shown in these figures. However, since the seal lower edge 71 is formed by heat sealing, they are in a straight-line shape. There may be some distortion, and these connecting portions may be somewhat rounded.

[0018] As shown in FIG. 4(a), the spout 3 is provided with a straw portion 31 that serves as an inlet for the contents, and a mouth portion 32 that serves as a filling port and a suction port for the contents. A male screw portion 33 is formed on the outer periphery of the lower part of the mouth portion 32 so that the cap can be screwed on and off, and a protrusion portion 38 for engaging the cap is formed below that. Further below that, a flange 37 is formed to fit into a guide rail when the container is fed to the filling device. Although not shown in the figure, a female screw portion that screws into the male screw portion 33 of the mouth portion 32 is formed on the inner periphery of the cap that seals the opening 3a of the spout 3. A sealant that seals the opening 3a after the contents are filled can be provided at the tip of the mouth portion 32, which can prevent the contents from leaking out of the mouth portion 32 even when the container is pressurized and heated for sterilization. These sealing materials are formed of a film made by laminating a synthetic resin film and a metal foil, and are welded to the tip opening 3a of the mouth portion 32 by a means such as heat sealing. A heat-sealed portion 34 for heat-sealing to the container body 2 is provided below the flange 37. A hole 36 is provided above the straw portion 31, which allows the contents to be easily sucked out. Ears 35 for reinforcing the strength of the portion where the hole 36 is formed and for stably positioning the spout 3 on the container body 2 are formed so as to extend downwardly continuous with the heat-sealed portion 34. As shown in Figures 4(a) and (b), the ears 35 are formed to have approximately the same length (approximately the same position) as the portion where the hole 36 is formed. By forming ears 35 in this manner, it is expected that the hydrogen-containing water will be guided to holes 36 so that the pet can suck in and drink the hydrogen-containing water by itself even with little suction force.

[0019] The hydrogen-containing water 6 filled inside the spouted packaging container 5 has a pH of 6.2 to 6.8, and both of the calcium ion concentration and magnesium ion concentration are less than 0.01 ppm. The hydrogen-containing water 6 has an oxidation-reduction potential of −500 mV or less and a dissolved hydrogen concentration of 0.8 ppm or more.

[0020] For example, the hydrogen-containing water 6 may have concentrations of various cations, such as calcium ions and magnesium ions, sodium ions, potassium ions, iron ions, copper ions, and zinc ions, as well as concentrations of various anions, such as phosphorus-containing ions, such as chloride ions and phosphate ions, nitrogen-containing ions, such as nitrate ions, and sulfur-containing ions, all of which are less than 0.01 ppm. The hydrogen-containing water 6 also has less than 0.01 ppm of substances (ions) that adversely affect the health of not only pets but also humans, such as heavy metals, such as chromium, cadmium, lead, and mercury, and arsenic.

[0021] The product capacity of the container 2 is not particularly limited, but for example, containers with a capacity of 100 mL to 2,000 mL, particularly 150 mL to 550 mL, specifically 150 mL, 180 mL, 200 mL, 220 mL, 250 mL, 280 mL, 300 mL, 350 mL, 400 mL, 450 mL, 500 mL, or 550 mL can be used. In this specification, the "product capacity" refers to the standard capacity (also called the appropriate filling amount or the indicated content amount) when the product is distributed or sold, and is usually several percent to 15% less than the maximum capacity that can be filled into the container.

[0022] The water (raw water) used to produce the hydrogen-containing water to be filled into the hydrogen-containing water drinkable product for pets of this invention is purified water. Purification methods include a method using a reverse osmosis (RO) membrane or a method using an ion exchange resin. Water purified by reverse osmosis (RO) has a pH of less than 6 due to the removal of carbonate ions. The water often tends to become acidic, which makes it undesirable for use as a hydrogen-containing water product for drinking, particularly for pets such as dogs and cats. Purification using ion exchange resins is a method of purifying water using cation exchange resins and anion exchange resins. The pH settles at around 6.5 (6.2 to 6.8), which is close to neutral, making it more desirable as raw water for drinking purposes.

[0023] The method for producing the hydrogen-containing water is not particularly limited, and various methods can be used, such as a bubbling method in which hydrogen gas supplied from a gas cylinder is dissolved in raw water (pure water in the case of the present invention), a pressure method in which hydrogen gas is filled into a pressure vessel from which air has been removed, and while maintaining the pressure of the hydrogen gas in the pressure vessel at, for example, 2 to 10 atmospheres, raw water (pure water) is sprayed into the pressure vessel in a shower-like manner to bring the hydrogen gas into contact with the raw water (pure water), and a membrane dissolution method using a hollow fiber membrane. The produced hydrogen-containing water may be filled into the spouted packaging container 5 by a conventionally known filling method and then sealed with the cap 4.

[0024] Example 2. Boxed kit The boxed kit of the present invention is a hydrogen-containing water product for drinking pets, in which the hydrogen-containing water is filled inside the spouted packaging container, and is loaded into a box in a horizontal position where the container body is kept approximately horizontal. The horizontal position includes both a position in which the front part of the bag of the hydrogen-containing water product faces up and down as shown in Figure 7(a) and a position in which the side part of the bag of the hydrogen-containing water product faces up and down as shown in Figure 7(b). In the boxing kit 10 shown in Fig. 5, the hydrogen-containing water product 1 is loaded into a box 11 in a horizontal position with its container body 2 kept substantially horizontal. Fig. 5 shows an embodiment in which the hydrogen-containing water product is installed so that the side portions of the bag face up and down, and the caps of the product face each other, and a partition material 12 made of cardboard or the like is provided between each pair of hydrogen-containing water products. In the embodiment shown in Fig. 5, the partition material 12 is provided to separate the multiple hydrogen-containing water products 1 into individual products, and is provided in a lattice pattern in a portion lower than the height of the container body installed so that it abuts against the periphery of the container body 2 of the hydrogen-containing water product 1 and that faces up and down. In the box 10 shown in Fig. 6, the hydrogen-containing water product 1 is loaded into the box 11 in a horizontal position with the container body 2 kept substantially horizontal. Fig. 6 shows an embodiment in which the hydrogen-containing water product is installed so that the side portions of the bag face up and down and the caps of the product face each other, and no partition is provided in this embodiment. The boxed kit may typically contain two or more, for example, 6, 12, 24, 30, or 60 hydrogen-containing water products packed in a box.

[0025] The box used in the boxing kit may be one that is large enough and durable enough to accommodate a plurality of hydrogen-containing water products for drinking pets, and may be, for example, a cardboard or corrugated cardboard box, or a resin container. The shape of the box may be a rectangular parallelepiped, and the size of the box may be appropriately selected depending on the number of hydrogen-containing water products to be loaded and the loading position. For example, when a single hydrogen-containing water product for drinking is loaded into the box, it is preferable to use a box having a length and width that allows the container body of the hydrogen-containing water product to just abut against the periphery of the box. When loading a plurality of hydrogen-containing water products, it is preferable to align them in one or more rows in the same direction with almost no gaps, and load them into a box having a length and width that allows the group of products in this aligned position to be packaged. The hydrogen-containing water products to be loaded may be stacked in multiple layers.

[0026] Example 3. Evaluation of storage stability of hydrogen-containing drinking water products for pets The larger the content (product volume) of hydrogen-containing drinking water products for pets, the This is advantageous in terms of the storage properties of hydrogen-containing water (how difficult it is for hydrogen to escape). However, in the spouted packaging container (aluminum pouch with a spout) used in the present invention, it is difficult to completely maintain the airtightness of the spout mouth (see mouth 32 in Figures 2 to 4) and the cap, and these parts allow slight communication between the space inside the container and the outside space, making it easy for hydrogen liberated from the hydrogen-containing water filled inside the container to gradually escape. The larger the capacity of the container, the smaller the proportion of the contact surface area between the cap / spout part and the outside space, which results in improved storage properties of hydrogen-containing water. On the other hand, small dogs and cats have a lower water intake than humans, so even if the product has a volume of 200 mL, they may not be able to drink it all in one sitting, and so the opened product is often recapped and stored. When a product is opened once, air enters the container from the mouth of the spout. If the product is recapped without removing the air and air remains inside the container, the hydrogen in the hydrogen-containing water is likely to be liberated into the remaining air due to contact with the remaining air. As mentioned above, a product with a large content volume is advantageous in terms of the storage of hydrogen-containing water when unopened, but the contact surface area between the remaining air and the hydrogen-containing water when recapped is relatively large, so in this case there is a risk that hydrogen will be easily lost and become a disadvantage. Below, we examined how easily air escapes from inside the container when recapping, and also examined the effect that the container's position during storage has on the hydrogen concentration of hydrogen-containing water.

[0027] [Test procedure] (1) Six bottles of hydrogen-containing water for drinking for pets (hereinafter simply referred to as "product") with a product volume of 550 mL were prepared. The spout-equipped packaging container used was a gusset type having gussets on the left and right sides of the container body as shown in Figure 2 above. (2) One bottle of the product was opened and the hydrogen concentration was measured (0 hour). (3) For the remaining 5 products, the caps were opened and 50 mL of hydrogen-containing water was drained out. After that, the container was pressed to raise the water level inside the container, causing a small amount of hydrogen-containing water to overflow, and then the container was recapped so that no air remained inside the container. (4) Five of these products were left to stand for seven days in a horizontal position with the side portions of the bags facing up and down as shown in Figure 7(b) above. (5) After leaving the container standing for 3 hours, 6 hours, 24 hours, 3 days, and 7 days, one bottle was opened and the hydrogen concentration was measured.

[0028] In (4) of the above test procedure, the test was carried out in the same manner as above, except that the container was left in an upward position (for example, the position shown in Figure 1) for 7 days, with the cap on top and the container body on the bottom, and the hydrogen concentration was measured.

[0029] The results obtained are shown in Table 1. [Table 1]

[0030] As shown in Table 1, even after opening, by recapping the container so that no air remains inside and storing it in a horizontal position, there was no significant change in the hydrogen concentration even after 7 days, and it was confirmed that the hydrogen concentration at the start of the test could be maintained. On the other hand, when stored facing up, the hydrogen concentration gradually decreased after three hours, and after seven days the hydrogen concentration had dropped by 75% compared to the start (0 hours). Furthermore, when discharging 50 mL of hydrogen-containing water in step (1) and when pushing the container to raise the water level inside the container in step (3), the hydrogen-containing water was able to be smoothly discharged and overflowed without a large amount of hydrogen-containing water being discharged or overflowed due to excessive force.

[0031] As described above, the hydrogen-containing water product for drinking for pets of the present invention is a product that allows the desired amount of hydrogen-containing water to be poured out without excessive overflowing from the container when the container is pressed, and this container characteristic of being easy to remove the contents also provides the characteristic of being easy to expel air if air gets inside. These container characteristics and the fact that the product is stored in a horizontal position allow the hydrogen concentration of the hydrogen-containing water to be maintained at a high level even when it is assumed that the opened product with a large content will be recapped and stored.

[0032] The hydrogen-containing drinking water product for pets of the present invention is suitable as a drinking product for pets such as dogs, cats, birds (parakeets, parrots, owls, canaries, Java sparrows, etc.), mammals (hamsters, guinea pigs, rabbits, ferrets, squirrels, pigs, etc.), and reptiles (snakes, lizards, chameleons, etc.), and is also preferably provided as a drinking product for livestock such as horses and cows. When providing (drinking) hydrogen-containing water to pets or livestock, the hydrogen-containing water may be directly consumed from the product container (FIG. 8), or the hydrogen-containing water may be transferred to a container for easier consumption. If the hydrogen-containing water product can be consumed in one go, there is no particular limitation on the container in which it is provided. However, since hydrogen in the hydrogen-containing water is easily lost when exposed to air, if the hydrogen-containing water product cannot be consumed in one go, it is important to provide it in a container that minimizes the surface area exposed to air. FIG. 9 is a diagram showing an example of a manner in which a pet (dog) drinks hydrogen-containing water from the hydrogen-containing water product for pets of the present invention that has been transferred to a provision container 61. As shown in FIG. 9, the provision container 61 contains hydrogen-containing water 6, and when a button 62 attached to the provision container 61 is pressed, a predetermined amount of liquid (hydrogen-containing water) comes out from a nozzle 63. The provision container 61 shown in FIG. 9 is one example and is not limited to the embodiment shown in this figure, but by using a provision container that dispenses water when desired in this way, it is possible to prevent the hydrogen-containing water from coming into contact with air as much as possible, and to maintain the dissolved hydrogen concentration. can be kept high. Furthermore, the hydrogen-containing water in the hydrogen-containing water product for drinking pets of the present invention has a calcium ion concentration and magnesium ion concentration of less than 0.01 ppm, so even if the hydrogen is lost, the water has a reduced mineral concentration and is of sufficient quality to be used as drinking water for animals such as pets.

[0033] The hydrogen-containing water product for drinking for pets of the present invention is hydrogen-containing water with a near-neutral pH value (6.2-6.8) and a reduced mineral concentration, such as calcium ion concentration and magnesium ion concentration of less than 0.01 ppm. Therefore, it is not only suitable for pets, but can also be used to prepare powdered milk for newborns, as milk can be prepared without upsetting the mineral balance. [Explanation of symbols]
