Description

The present invention relates to a liquid container.

Conventionally, it is known that metal ions such as silver ions are effective for sterilization and sterilization.

Then, a container that produces water containing silver ions using a container having silver as an inner coating has been proposed (for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2013-99919

In order to safely use water containing silver ions (hereinafter referred to as "silver ion water"), the content of silver ions in the silver ion water needs to be within a predetermined range. If the content of silver ions is too low, the bactericidal effect is weak and bacteria cannot be effectively reduced. On the other hand, if the content of silver ions is too high, it adversely affects human health.

Based on the above, the present invention provides a liquid container capable of adjusting the content of silver ions in silver ion water within a predetermined range.

The first invention is a liquid container having a container body for storing a liquid, in which a carrier carrying silver and a cation emitter emitting cations are dispersed in the container body. When the liquid is stored in the container body, silver ions are released into the liquid from the silver carried on the carrier, and the cation emitter releases the cations. A liquid container configured to function as a first limiting means of limiting the release of the silver ions from the silver into the liquid.

The inventor of the present invention contains silver in a container made of resin, and further contains a cation emitter (for example, copper), so that when the liquid is stored in the container body, silver ions in the liquid are contained. It has been found that the content of can be adjusted to an appropriate predetermined range. The "predetermined range" is defined as a range of silver ion content within a range that exerts an effective bactericidal or sterilizing effect and does not impair human health. According to the configuration of the first invention, silver ions are released from the silver supported on the carrier contained in the container body into the liquid stored in the container body. Then, the release of silver ions from silver is limited by the cations released from the cation emitter, and the content of silver ions in the liquid is adjusted within a predetermined range.

In the second aspect of the invention, in the configuration of the first invention, the container body is further composed of a porous body dispersed in the resin, and the porous body contains the silver ions released from the silver. The liquid container according to claim 1, which is configured to function as a second limiting means for limiting the release of the silver ions from the silver into the liquid by capturing.

In order to adjust the content of silver ions in the liquid, the inventor of the present invention is effective in dispersing the porous body in addition to dispersing the cation emitter in the resin constituting the container body. I found that. If the content of the cation emitter is increased too much in order to adjust the content of silver ions in the liquid to a relatively low range within a predetermined range, the effect of limiting the release of silver ions becomes too large. The silver ion content of silver ion water cannot be within the range. On the other hand, the release of silver ions is appropriately restricted by containing a porous body instead of further increasing the content of the cation emitter after containing a predetermined amount of the cation emitter. It is possible to generate silver ionized water in which the content of silver ions is relatively low within a predetermined range. In this regard, according to the configuration of the second invention, since the container body contains a porous body that functions as a second limiting means, the release of silver ions is appropriately restricted, and the content of silver ions is within a predetermined range. A certain silver ionized water can be produced.

In the third aspect of the invention, in the configuration of the first invention, in the container body, the content of the silver in the whole container body and the content of the cation emitter are such that the liquid is stored in the liquid container. It is a liquid container in which the content of the silver ion in the silver ion water generated by releasing the silver ion into the liquid is specified to be a predetermined content in a predetermined range.

In the fourth invention, in the configuration of the second invention, in the container body, the content of the silver, the content of the cation emitter, and the content of the porous body in the whole container body are different. When the liquid is stored in the liquid container, the content of the silver ions in the silver ion water generated by releasing the silver ions into the liquid is specified to be a predetermined content within a predetermined range. It is a liquid container.

In the fifth aspect of the invention, in any of the first to fourth aspects of the invention, the outer surface of the container body is configured as a blocking layer that blocks the transmission of light, and the blocking layer is the light. It is a liquid container configured as a preventive means for preventing the disappearance of the silver ions released into the liquid by blocking the permeation of the light.

The inventor of the present invention has found that the silver ions released into a liquid are extinguished by the action of light. This led to the idea of a technical idea to block the transmission of light to the part of the container body that stores the liquid. In this regard, according to the configuration of the fifth invention, since the liquid container has a blocking layer that blocks the transmission of light, the content of silver ions in the liquid can be maintained at a predetermined content.

In the sixth invention, in the configuration of the third invention, the predetermined content of the silver ion in the silver ion water is 0.02 ppm or more and 0.50 ppm or less, and the silver content in the container body is 0. It is a liquid container having .04% by weight or more and 0.50% by weight or less, and the content of the cation emitter in the container body is 0.10% by weight or more and 9.00% by weight or less.

In the seventh invention, in the configuration of the fourth invention, the predetermined content of the silver ion in the silver ion water is 0.02 ppm or more and 0.50 ppm or less, and the silver content in the container body is 0. It is 0.04% by weight or more and 0.50% by weight or less, and the content of the cation emitter in the container body is 0.10% by weight or more and 9.00% by weight or less, and the porous body in the container body has. A liquid container having a content of 0.50% by weight or more and 35.00% by weight or less.

According to the liquid container according to the present invention, the content of silver ions in silver ion water can be adjusted within a predetermined range.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The configuration that can be appropriately implemented by those skilled in the art will be omitted, and only the basic configuration of the present invention will be described.

<First embodiment>
Embodiments of the present invention will be described below with reference to the drawings. In the present specification, the expression "vertical direction" is referred to as "vertical direction" with reference to the vertical direction in FIG. Specifically, the direction connecting the container body 2 and the pump member 10 is the vertical direction. The direction in which the pump member 10 is located is referred to as an upward direction, and the direction in which the container body 2 is located is referred to as a downward direction. The direction perpendicular to the vertical direction is called the "horizontal direction". The content shall mean% by weight.

FIG. 1 is a side view of the container 100 according to the first embodiment of the present invention. The container 100 is composed of a container body 2 and a pump member 10. The upper end portion of the container body 2 is open, and the pump member 10 is arranged at the upper end portion thereof. Water is stored in the container body 2. The container body 2 is a cylindrical member with a closed bottom. The suction tube 6 is arranged inside the container body 2. The suction tube 6 is a cylindrical member having an open bottom and top. The suction tube 6 is connected to the pump member 10. The container 100 is configured so that the water stored in the container main body 2 can be sucked up and ejected to the outside through the suction tube 6 by the action of the pump member 10. The container 100 is an example of a liquid container. The container body 2 is an example of a container body for storing a liquid. Water is an example of a liquid.

FIG. 2 is a schematic cross-sectional view of the container body 2 cut in the vertical direction. The space S1 is defined by the inner surface 2a of the container body 2, and water is stored in the space S1. In addition, "water" may be tap water having an average property in Japan.

The suction tube 6 (see FIG. 1) is a hollow member through which water passes through the inner space. The suction tube 6 is arranged at a position where it does not come into contact with the inner surface of the container body 2.

The pump member 10 is composed of a known manual pump mechanism. The parts of the pump member 10 are formed by injection molding a resin such as polypropylene (PP), for example. A known pump mechanism is, for example, two check valves or a mechanism similar to a check valve arranged one above the other and pressing the head portion of the pump to discharge water between the two valves and then the head of the pump. By returning the part to its original position, the water inside is sucked up between the two valves.

In the present embodiment, when the user presses the head portion of the pump member 10 from above, a certain amount of water is discharged to the outside from the discharge port, and the head portion is also formed by the urging member provided inside the pump member 10. When returning to the position of, the water in the container body 2 is sucked from the suction tube 6 in a fixed amount.

FIG. 3 is an enlarged conceptual diagram of the peripheral wall of the container body 2. Specifically, FIG. 3 is an enlarged conceptual diagram of a region A1 of the peripheral wall of the container body 2 of FIG. The peripheral wall of the container body 2 is configured to have a thickness of W1. An outer layer 2c is formed on the outer side of the outer surface 2b of the container body 2. The outer layer 2c is formed of a paint that blocks the transmission of light. That is, the outer layer 2c is formed by applying a light-impermeable paint to the outer surface 2b. The outer layer 2c is an example of a blocking layer.

The container body 2 is formed by dispersing the carrier 30 carrying silver and the copper powder 40 in the resin 4. Resin 4 is an example of resin. The carrier 30 is an example of a carrier that carries silver. Copper powder 40 is an example of a cation emitter that emits cations. The metal constituting the cation emitter is not limited to copper, and may be any metal having a higher ionization tendency than silver.

The container body 2 is formed by mixing a carrier 30, a copper powder 40, and a resin 4, and adding an appropriate coupling material such as a silane coupling material and other additives as necessary to form the container body 2. The carrier 30 is prepared as a powder. As a method of dispersing the carrier 30 and the copper powder 40 in the resin 4, for example, a mixed powder in which a predetermined amount of the carrier 30 and the copper powder 40 are dispersed in the powder of the resin 4 is prepared, and the mixed powder is melted and molded. Implement by doing. The molding method is, for example, blow molding. The molding method is not limited to blow molding, and injection molding may be adopted, for example.

As the type of the resin 4 constituting the container body 2, for example, a polyolefin-based resin such as polypropylene, a polystyrene-based resin, or a polyester-based resin can be used. As the resin 4, a resin that does not contain a coloring agent such as a pigment is used. The inventor of the present invention has found that a colorant such as a pigment suppresses the release of silver ions from silver, and further finds that it is difficult to control the degree of the suppression. Therefore, the resin 4 is limited to those that do not contain colorants such as pigments. Then, in order to prevent light from entering the inside of the container main body 2, the outer layer 2c is formed as described above.

As the carrier 30, for example, a silver-based inorganic antibacterial agent in which silver is supported on zeolite is used. As the silver-based inorganic antibacterial agent, for example, Zeomic (registered trademark) manufactured by Shinanen Zeomic Co., Ltd. (1-1 Nakagawahonmachi, Minato-ku, Nagoya City, Aichi Prefecture) is used.

As the copper powder 40, for example, copper particles of the "copper nanoparticles SFCP series" manufactured by Fukuda Metal Foil Powder Industry Co., Ltd. (20, Nishinoyama Nakatomi-cho, Yamashina-ku, Kyoto) can be used. Alternatively, as the copper powder 40, cuprous oxide particles manufactured by Furukawa Chemicals Co., Ltd. (3-7-196 Ono, Nishiyodogawa-ku, Osaka City, Osaka Prefecture) may be used.

The content of silver in the entire container body 2 and the content of copper powder 40 are set to a predetermined content within a range in which the content of silver ions in the silver ion water generated by storing water in the container 100 is specified in advance. It is stipulated to be. The predetermined content of silver ions in the water in a predetermined range is defined as an appropriate range that effectively exerts a sterilizing or sterilizing effect and does not adversely affect the human body. The predetermined content of silver ions in the water in the predetermined range is, for example, 0.02 ppm (mg / L) or more and 0.50 ppm or less, preferably 0.10 ppm or more and 0.42 ppm or less, and more preferably. , 0.10 ppm or more and 0.25 ppm or less, more preferably 0.18 ppm or more and 0.25 ppm or less, and further preferably 0.20 ppm or more and 0.25 ppm or less. Silver ion If the concentration of silver ion in water is too low, the sterilizing or sterilizing effect will be insufficient. On the other hand, if the concentration of silver ions in the silver ion water is too high, it may adversely affect the human body. Therefore, it is necessary to control the concentration of silver ions in the silver ion water to an appropriate range that sufficiently exerts a sterilizing or sterilizing effect and does not adversely affect the human body. According to the configuration of the present embodiment, the content of silver ions in the silver ion water can be controlled in an appropriate range.

The silver content in the entire container body 2 is defined in the range of 0.04% by weight or more and 0.50% by weight or less, and the silver content is preferably 0.04% by weight or more and 0.32% by weight or less. It is specified in the range, more preferably 0.11% by weight or more and 0.25% by weight or less, and further preferably 0.16% by weight or more and 0.21% by weight or less. Silver is supported on the carrier 30. If the silver content is too low, the elution amount of silver ions will be too low and the sterilizing or sterilizing effect will be insufficient. On the other hand, if the silver content is too high, the elution amount of silver ions becomes excessive, which may adversely affect the human body.

The content of the cation emitter (copper) in the entire container body 2 is defined in the range of 0.10% by weight or more and 9.00% by weight or less, and preferably 0.20% by weight or more and 5.00% by weight or less. More preferably, it is 0.30% by weight or more and 3.00% by weight or less. For example, the content of the copper powder 40 is specified in the range of 0.10% by weight or more and 4.00% by weight or less. If the copper content is too low, the effect of limiting the elution of silver ions is too small, allowing excessive elution of silver ions. On the other hand, if the copper content is too high, the elution of silver ions will be excessively restricted. The copper ions released from the copper powder 40 reduce the decrease in the amount of silver carried on the carrier 30 by limiting the elution of silver ions from the silver supported on the carrier 30, and the silver ion generator. It also has the effect of prolonging the product life of the container 100.

In the present embodiment, the content of the carrier 30 in the entire container body 2 is 4.0% by weight. The silver content in the carrier 30 is 4.0 weight percent. As a result, the total silver content of the container body 2 becomes 0.16% by weight.

In the present embodiment, the content of the copper powder 40 in the entire container body 2 is 1.0% by weight.

By storing water in the container body 2 with reference to FIGS. 4 and 5, silver ions are released from the silver constituting the container body 2, and silver ion water containing a predetermined content of silver ions is put into water. A state in which a predetermined amount of silver ionized water is generated will be conceptually described. The description of the chemical reaction formula is omitted. In FIGS. 4 and 5, the description of the pump member 10 is omitted, and the container body 2 and the suction tube 6 are shown.

As shown in FIG. 4, when the water 60 is stored in the container body 2, the water 60 comes into contact with the inner surface 2a of the container body 2.

Then, as shown in FIG. 5, silver ions (Ag ⁺ ) are released from the silver supported on the carrier 30 constituting the container body 2. Further, copper ions (Cu ²⁺ ) are released from the copper powder 40, and the release of silver ions from the carrier 30 is restricted. As a result, silver ion water 62 containing a predetermined content of silver ions can be generated without excessively releasing silver ions from the container body 2. Then, since the outer layer 2c formed on the outer surface 2b of the container body 2 prevents light from reaching the inside of the container body 2, the silver ions contained in the silver ion water 62 are not extinguished and have a predetermined content. Is maintained. The silver ions from the silver carried on the carrier 30 are eluted, but the degree of elution of the silver ions is limited by the copper ions released from the copper powder 40 and contains a predetermined content of silver ions. Since the silver ionized water 62 is generated and the outer layer 2c prevents light from reaching the inside of the container body 2, the silver ion content of the silver ionized water 62 is maintained. Further, since the outer layer 2c prevents light from reaching the inside of the container body 2, the elution of silver ions from the silver carried on the carrier 30 and the elution of copper ions from the copper powder 40 are light. Since it is not affected by silver ion water 62, silver ion water 62 containing a planned content of silver ions can be produced.

FIG. 6 shows the experimental results in which water was put into the container body 2 to generate the concentration of silver ions when a predetermined time had passed. 0.16% by weight of silver and 1.0% by weight of copper are dispersed with respect to the weight of the entire container body 2 to form the container body 2, and silver after 6 hours has passed at room temperature (RT: 25 degrees Celsius). The ion concentration was measured. The silver ion concentration was measured using a silver ion measuring instrument AGT-131 manufactured by Nippon Ion Co., Ltd. (3-2-24 Miyasaka, Setagaya-ku, Tokyo). When the silver ion concentration was measured after 6 hours, all the silver ion water in the container body 2 was discarded, water was put into the container body 2 again, and the experiment of measuring the silver ion concentration after 6 hours was repeated. .. The silver ion concentration decreased from the first to the fourth time, but became stable after the fifth time. In the example of FIG. 6, the silver ion concentration at the first time was about 0.18 ppm, but gradually decreased after the second time, and the silver ion concentration became stable at about 0.15 ppm after the fifth time.

According to an experiment, the inventor of the present invention found that when water was added to the container body 2, when the silver content in the container body 2 was 0.16% by weight, copper was not blended at all. It was confirmed that the silver ion concentration of the silver ion water produced by the container 100 was reduced by about 50% by blending 1.0% by weight. Then, it was confirmed that when 5.0% by weight of copper was blended under the same conditions, the silver ion concentration of the silver ion water was reduced by about 50% as compared with the case where 1.0% by weight of copper was blended. Furthermore, it was confirmed that when 0.1% by weight of copper was blended under the same conditions, the silver ion concentration of the silver ion water was substantially the same as that when copper was not blended at all. This is because when the silver content is 0.16% by weight, the copper content is larger than 0.1% by weight and effectively limits the elution of silver ions in the range of 1.0% by weight or less. It means that there is a peculiar numerical value or numerical range. If the silver content is not limited to 0.16% by weight and is generalized, the ratio S1 (Xcu / Xag) of the copper content Xcu to the silver content Xag is 0.625 <S1 ≦ 6.25. It can be understood that there is a peculiar numerical value or numerical range in the range of.

FIG. 7 is a diagram showing a usage example of the container 100. For example, the entrance mat 202 is arranged at the entrance / exit of the house 200. The mother 204 sprays the silver ionized water 62 generated by the container 100 onto the entrance mat 202 and soaks it. When a child 206 or a dog 208 returning from going out steps on the entrance mat 202 before entering the house 200, the effect of the copper ions contained in the silver ion water 62 that has soaked into the entrance mat 202 causes the shoes of the child 206 to pass. It can reduce bacteria on the bottom and dog's feet.

<Second embodiment>
The second embodiment will be described with reference to FIGS. 8 and 9, focusing on the differences from the first embodiment. In the second embodiment, as the configuration of the container body 2A, the silver content, the cation emitter content, and the porous body content in the entire container body 2A are stored and generated in the container 100. The content of silver ions in the silver ion water is specified so as to be a predetermined content in a predetermined range. The porous body is an example of the second limiting means.

Specifically, the predetermined content of silver ions in the silver ion water generated by storing water in the container 100 is, for example, 0.02 ppm (mg / L) or more and 0.50 ppm or less, preferably 0. It is 10 ppm or more and 0.42 ppm or less, more preferably 0.10 ppm or more and 0.25 ppm or less, further preferably 0.18 ppm or more and 0.25 ppm or less, and further preferably 0.20 ppm or more and 0.25 ppm. It is as follows.

In the entire container body 2A, the silver content is specified in the range of 0.04% by weight or more and 0.50% by weight or less, and preferably 0.04% by weight or more and 0.32% by weight or less. More preferably, it is specified in the range of 0.11% by weight or more and 0.25% by weight or less, and more preferably, it is specified in the range of 0.16% by weight or more and 0.21% by weight or less. Silver is supported on zeolite.

The content of the cation emitter (copper powder 40) in the entire container body 2A is specified in the range of 0.10% by weight or more and 9.00% by weight or less, and preferably 0.20% by weight or more and 5.00% by weight. % Or less. For example, the content of the copper powder 40 is specified in the range of 0.10% by weight or more and 4.00% by weight or less.

The content of the porous body is specified by 0.50% or more and 35.00% by weight or less. The porous body uses powder, for example, ceramic powder 50, which is a ceramic powder (see FIG. 8).

FIG. 8 is an enlarged conceptual diagram of the container wall of the container body 2A. The container body 2A is formed by dispersing silver-supporting carrier 30, copper powder 40, and ceramic powder 50 in the resin 4.

When water is stored in the container body 2A, silver ions are eluted from the silver supported on the carrier 30. The elution of silver ions is limited by the copper ions eluted from the copper powder 40. Further, the silver ions eluted from silver are captured by the ceramic powder 50, and the amount released into water is limited. The silver ion concentration of the silver ion water generated by putting water in the container body 2A can be limited by the copper ions from the copper powder 40, and a relatively high predetermined content can be realized. However, if the content of the copper powder 40 is increased in order to adjust the silver ionized water to a predetermined content in a relatively low range, the elution of silver ions is excessively restricted. On the other hand, by containing the ceramic powder 50 instead of increasing the content of the copper powder 40 in the container body 2A, it is possible to generate silver ionized water in a predetermined content in a relatively low range. .. In the present embodiment, the silver ion concentration in silver ion water is effectively controlled by using a plurality of methods having different principles for controlling the silver ion concentration in silver ion water. That is, the control principle by the copper powder 40 is due to the difference in ionization tendency from silver, and controls the elution of ions from silver itself. On the other hand, a porous body such as ceramic powder does not suppress the elution of ions from silver itself, but controls the concentration of silver ions in silver ion water by capturing the ions eluted from silver. It is a thing.

FIG. 9 shows the experimental results in which water was put into the container body 2A and the concentration of silver ions was measured after a predetermined time. 0.16% by weight of silver, 1% by weight of copper, and 10% by weight of ceramic are dispersed in the entire container body 2 to form the container body 2, and silver ions are formed after 6 hours at room temperature (RT: 25 degrees Celsius). The concentration was measured. The silver ion concentration decreased from the 1st time to the 4th time, but became stable at about 0.07 ppm after the 5th time.

The second embodiment is characterized in that the container body 2A contains copper and a porous body in order to control the content of silver ions eluted in the water stored in the container body 2A. For example, by keeping the copper content the same as in the first embodiment and containing a predetermined amount of the porous body, silver ion water having a relatively low silver ion content can be produced. For example, if the predetermined content of silver ionized water is 0.02 ppm or more and 0.50 ppm or less, 0.02 ppm or more and 0.10 ppm is a relatively low predetermined content, and 0.15 ppm or more and 0.50 pp or less. Is a predetermined content in a relatively high range. The first embodiment described above produces silver ionized water having a relatively high range of predetermined content, and the second embodiment produces silver ionized water having a relatively low range of predetermined content. Can be done.

<Comparison example>
FIG. 10 shows the experimental results when the copper content is increased instead of adding ceramic to the container body 2, unlike the second embodiment. As shown in FIG. 10, 0.16% by weight of silver and 10.0% by weight of copper are dispersed in the entire container body 2 to form the container body 2, and after 6 hours at room temperature (25 degrees Celsius). The silver ion concentration was measured. As a result, the silver ion concentration drops sharply after the fourth time, and the silver ion content becomes less than the predetermined content.

From the second embodiment and the comparative example, when the silver ion concentration is adjusted to a predetermined content in a relatively low range, the copper content is not increased, but the copper content is adjusted to an appropriate content. It turns out that it is effective to add ceramic while maintaining it.

The liquid container of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention. In addition, each of the above embodiments can be appropriately combined as long as there is no technical contradiction.
