Or processed by column chromatography. In addition, these antioxidant substances derived from natural products are highly safe for living bodies, but depending on the taste and scent of the substance itself, when added to drinking water or existing beverages, the taste and flavor of the beverage There was a problem that there is a possibility of damaging.

  Therefore, the present invention is completely different from the conventional technology, has no possibility of impairing the taste and flavor of the beverage, and can prevent oxidation only by containing drinking water or an existing beverage in a container, An object of the present invention is to provide a beverage container capable of lowering the oxidation-reduction potential and improving the beverage flavor.

  The beverage container according to the invention of claim 1 is a beverage container for preventing oxidation of beverages including drinking water, soft drinks and alcoholic beverages and lowering the oxidation-reduction potential. A synthetic resin container fixed inside the container, and a space of a predetermined capacity is formed between the inner surface of the metal container and the outer surface of the synthetic resin container, and the oxidation-reduction potential is negative in the space.

The beverage container according to the invention of claim 1 is a beverage container for preventing oxidation of beverages including drinking water, soft drinks and alcoholic beverages and lowering the oxidation-reduction potential. A synthetic resin container fixed inside the container, and a space of a predetermined capacity is formed between the inner surface of the metal container and the outer surface of the synthetic resin container, and the oxidation-reduction potential is negative in the space. The slurry which is.
The present inventors have conducted extensive experimental research on the antioxidant action (reduction action) of the quartz porphyry gelled material obtained by gelling fine powder of quartz porphyry including quartz diorite and barleystone. The slurry of quartz porphyry gelled material is put in a metal container, and the tap water stored in the synthetic resin container is immersed therein, so that the redox potential (ORP) of the tap water stored in the synthetic resin container is In addition, the inventors have found that the negative value increases, and have completed the present invention based on this finding.

  The experimental results of the present inventors will be described. A gel-like slurry obtained by adding distilled water to a fine powder of quartz diorite, which is a kind of quartz porphyry, and mixing with a ball mill, is made of a metal with a lid. It put in the container, put the tap water put in the container made from a synthetic resin in it, covered, and measured the time-dependent change of the ORP value of tap water with the oxidation-reduction potential (ORP) measuring device. At the same time, the change with time of the ORP value of the slurry was also measured with an ORP measuring device.

  As a result, the slurry continued to show a large negative ORP value for more than a week, and the ORP value of tap water initially showed a positive value, but changed to a negative value in about half a day, and became negative as the date passed. The value of became larger. Moreover, when the present inventors tried drinking the tap water which showed the negative ORP value, the tap odor disappeared and the refreshing flavor was shown.

  As described above, the scientific basis for lowering the ORP value of tap water simply by immersing tap water in a synthetic resin container into a slurry showing a large negative ORP value is unknown, but a metal container with the same slurry. When the tap water put in was immersed, such an effect was not obtained at all. Therefore, when considered electromagnetically, electrostatic induction occurs between the outer slurry and the inner beverage with the synthetic resin container as an insulator interposed therebetween, and a metal made of a slurry containing a slurry showing a large negative ORP value. The container has a larger negative potential, and it is assumed that electricity flows between the metal container and the beverage that is a conductor.

Therefore, by putting a slurry showing a large negative ORP value in a metal container and immersing the drink in a synthetic resin container, the ORP value of the drink is lowered in this way to prevent oxidation and improve the flavor. It is considered that the function and effect are obtained.
In this way, there is no possibility of impairing the taste or flavor of the beverage, and it is possible to prevent oxidation simply by containing drinking water or existing beverage, and the oxidation-reduction potential can be lowered to improve the beverage flavor. It becomes the container for drinks which can be improved.

The slurry is made of silicic acid (SiO ₂ ), aluminum (Al), iron (Fe), calcium (Ca), magnesium (Mg), potassium (K), carbon (C), strontium (Sr), zinc ( Zn) -containing quartz porphyry gelled product with a negative oxidation-reduction potential formed by gelation of a fine powder of quartz porphyry, and in the inventors' experiment, the beverage most put in a beverage container It has been found that the effect of lowering the ORP value is large.

The quartz porphyry is quartz diorite. As a result of repeated earnest experimental research by the present inventors, when a slurry made of fine powder of quartz diorite is used among various quartz porphyry, the ORP value of the beverage placed in the beverage container is the most. It was found that the effect of lowering was great.

It becomes the container for drinks which can be improved.

  In the beverage container according to the invention of claim 2, the inner volume of the synthetic resin container is in the range of 0.5 to 3.0 times the capacity of the space of the predetermined capacity, more preferably 1.5 to 2. It is within the range of 5 times.

  The larger the amount of slurry surrounding the synthetic resin container relative to the amount of beverage placed in the synthetic resin container, the greater the effect of lowering the ORP value of the beverage. Considering the case where the volume of the slurry is filled with the slurry, if the amount of the beverage is less than 0.5 times the amount of the slurry, the effect of lowering the ORP value of the beverage is increased, but only a small amount of beverage can be accommodated. It is uneconomical. On the other hand, when the amount of the beverage exceeds 3.0 times the amount of the slurry, the effect of lowering the ORP value of the beverage becomes small, and a sufficient reduction effect cannot be obtained. Therefore, the inner volume of the synthetic resin container is preferably in the range of 0.5 to 3.0 times the volume of the predetermined volume space.

  Furthermore, the direction in which the amount of the beverage is 1.5 times or more the amount of the slurry is more economical because it can accommodate more beverages, and the amount of the beverage is 2.5 times or less of the amount of the slurry, Since the effect of lowering the ORP value of the beverage is greatly exerted, the inner volume of the synthetic resin container is more preferably in the range of 1.5 to 2.5 times the volume of the predetermined volume space.

  In this way, there is no possibility of impairing the taste or flavor of the beverage, and it is possible to prevent oxidation simply by containing drinking water or existing beverage, and the oxidation-reduction potential can be lowered to improve the beverage flavor. It becomes the container for drinks which can be improved.

Since PET bottles are used on a large scale in distribution processes and stores today as containers for a wide variety of beverages and the like, and can be obtained at a very low price with a desired capacity, the beverage containers according to the present invention It is extremely suitable as a synthetic resin container. That is, the cost of the beverage container according to the present invention can be reduced, and beverage containers of various capacities can be easily manufactured.

  In this way, there is no possibility of impairing the taste or flavor of the beverage, and it is possible to prevent oxidation by simply containing drinking water or an existing beverage in the container, and it is possible to lower the oxidation-reduction potential and It becomes the container for drinks which can improve flavor.

  Hereinafter, a beverage container according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a longitudinal sectional view showing the entire structure of a beverage container according to an embodiment of the present invention.

  As shown in FIG. 1, a beverage container 1 according to the present embodiment has a PET (polyethylene terephthalate) bottle 3 as an organic synthetic resin container having a predetermined capacity inside an aluminum container 2 as a metal container. It is fixed with a gap so as to form a space 4. A space 4 having a predetermined capacity is filled with a slurry 5 in which a fine powder of quartz diorite as a kind of quartz porphyry is gelled and dispersed in distilled water.

  Here, the manufacturing method of the slurry 5 which gelatinized the fine powder of quartz diorite and made it disperse | distribute to distilled water is demonstrated. Distilled water is added to the fine powder of quartz diorite, and this is placed in a wet ball mill and rotationally mixed to obtain a gelled slurry 5. In the present embodiment, the slurry 5 was produced by adding 20% by weight of fine powder of quartz diorite to 80% by weight of distilled water. Table 1 shows the results of fluorescent X-ray analysis of the components of the fine powder of quartz diorite used for the production of slurry 5 according to the present embodiment.

As shown in Table 1, the fine powder of quartz diorite used in the present embodiment contains the most silicic acid (SiO ₂ ), and then aluminum (Al), iron (Fe), calcium (Ca). , Magnesium (Mg), potassium (K), and carbon (C). In addition, strontium (Sr), zinc (Zn), phosphorus (P), copper (Cu), manganese (Mn), and nickel (Ni) are contained in trace amounts.

  Next, the manufacturing method of the container 1 for drinks concerning this Embodiment is demonstrated with reference to FIG. As shown in FIG. 1, the aluminum container 2 is formed of a cap 2A, an upper part 2B, a body part 2C, and a bottom part 2D, and an internal thread 2b corresponding to the male thread 3a of the PET bottle 3 is provided on the inner wall of the upper part 2B. It has been. Further, as shown in FIG. 1, the partial caps 2A, the upper part 2B, the body part 2C, and the bottom part 2D of the aluminum container 2 can be detachably assembled by a combination of male and female screws, respectively.

  The procedure for producing the beverage container 1 is as follows. First, a compression curable adhesive is applied to the entire internal thread 2b of the inner wall of the upper part 2B of the aluminum container 2, and the male thread 3a of the PET bottle 3 is firmly screwed in as much as possible to cure the compression curable adhesive. The bottle 3 is fixed to the upper part 2 </ b> B of the aluminum container 2. Similarly, the compression curable adhesive is applied to the entire female screw of the upper part 2B of the aluminum container 2 and the male screw of the body 2C of the aluminum container 2 is firmly screwed in as much as possible to cure the compression curable adhesive. The upper part 2B and the body part 2C of the aluminum container 2 are integrated.

  As a result, a space 4 having a predetermined capacity is formed between the outer surface of the PET bottle 3 and the upper surface 2B of the aluminum container 2 and the inner surface of the body portion 2C, so that the bottom surface of the PET bottle 3 is directed directly upward. The slurry 5 produced by the above-described procedure is poured into this space 4 and filled. And the internal thread of the bottom part 2D is screwed in the external thread of the trunk | drum 2C of the aluminum container 2, and the slurry 5 is made into a sealing state. Here, the bottom 2D may be bonded and fixed to the body 2C with a compression curable adhesive, or may be detachable without using an adhesive.

  In this way, the beverage container 1 according to the present embodiment shown in FIG. 1 is manufactured. Here, the capacity of the beverage container 1, that is, the capacity of the PET bottle 3 is 500 ml, and the capacity of the aluminum container 2 is 800 ml. Accordingly, the capacity of the space 4 having a predetermined capacity is (800 ml− (500 ml + the thickness of the PET bottle 3) = 300 ml−α). As a result, the internal capacity of the PET bottle 3 as an organic synthetic resin container is approximately 1.7 times the capacity of the space 4 with a predetermined capacity, so that a sufficient amount of beverage can be put into the space 4 with the predetermined capacity. The amount of the slurry 5 to be accommodated is also a sufficient amount.

  Various beverages were put in the beverage container 1 (in the PET bottle 3) as test specimens, and the change with time of the oxidation-reduction potential (ORP) was measured with an oxidation-reduction potential (ORP) measuring device. As ORP measuring instruments, two types of ORP measuring instruments, Horiba F53 and Takemura OM-68, were used. Takemura OM-68 has a measurement range (measurement limit) of ± 600 mV.

  First, for tap water, the ORP's sample A is simply put in a PET bottle with a normal capacity of 500 ml and the specimen B is put in the beverage container 1 according to the present embodiment. The change with time was measured using a Takemura OM-68 as an ORP measuring instrument. For reference, the change over time of the ORP of the slurry 5 was also measured. The measurement results are shown in Table 2 (unit: mV).

  As shown in Table 2, the tap water of the specimen A has a positive ORP value consistently and hardly changes with time. On the other hand, the tap water of the specimen B put in the beverage container 1 according to this embodiment has a negative ORP value already half a day later, and the negative value increases as the day passes. ing. The ORP value of the slurry 5 consistently indicates -600 mV, which is the measurement limit of Takemura OM-68 of the ORP measuring instrument.

  Next, tap water and other soft drinks were used as specimens, and the temporal change of ORP was measured using two types of Horiba F53 and Takemura OM-68 as ORP measuring instruments.

  As Specimen 1 to Specimen 4, tap water was used. As a general rule, the specimen 1 was measured for changes in ORP over time when placed in the beverage container 1 every day. Specimen 2 and Specimen 3 were charged with tap water in a 300 ml aluminum bottle, and slurry 5 (50 g of slurry for Specimen 2 and 150 g of slurry for Specimen 3) was wrapped in a transparent nylon film and sealed. A film pack was inserted and measured. Specimen 4 contains 900 ml of tap water in a glass water bottle, and a sealed film pack in which 300 g of slurry 5 is wrapped in a transparent nylon film, and the change in ORP over time is measured every day in principle. did.

  Furthermore, the test sample 5 was measured using a sports drink Pocari Sweat (registered trademark), and the test sample 6 was measured using an orange juice every day on the basis of a change in ORP over time. The measurement results of the temporal change of ORP for Specimen 1 to Specimen 6 are shown in Table 3 (unit: mV).

  As shown in Table 3, when comparing the measured values of Horiba F53 and Takemura OM-68 as a whole, Horiba F53 tends to have a higher ORP value. In all cases, the effect of lowering the oxidation-reduction potential by the slurry 5 appears remarkably. In addition, as shown in the measurement results of the specimen 5 and the specimen 6 as well as tap water, the effect of lowering the oxidation-reduction potential is also noticeable for soft drinks. In addition, when specimens 1 to 4 are compared, it can be seen that the effect of lowering the redox potential increases as the amount of slurry 5 increases with respect to the amount of tap water.

  Further, a carbonated beverage and an alcoholic beverage were also subjected to a measurement test for the effect of lowering the oxidation-reduction potential by the slurry 5. Coca-Cola (registered trademark) is used as the specimen 7, the ginger ale is used as the specimen 8, the sparkling liquor having an alcohol content of 5.5% is used as the specimen 9, and the alcohol content is 25% as the specimen 10. Shochu was used. All of Specimen 7 to Specimen 10 are placed in a 300 ml aluminum bottle, and a film pack sealed with 100 g of a transparent nylon film is placed in it, and the change in ORP over time is one day in principle. Measured every time. The measurement results are shown in Table 4 (unit: mV).

  As shown in Table 4, the test piece 7 and the test piece 8 that are carbonated drinks have a positive ORP value at the start of measurement, but the ORP value becomes a negative value after 1 day has elapsed. It has become. However, for the specimen 7 and the specimen 8, the effect that the slurry 5 lowers the ORP value does not last long, and the ORP value returns to a positive value after one week. On the other hand, the specimen 9 and the specimen 10 that are alcoholic beverages both show a positive ORP value at the start of measurement, but the specimen 9 has a large negative ORP value after 1 day. The specimen 10 also has a negative ORP value after 2 days, and the effect of the slurry 5 lowering the ORP value for both the specimen 9 and the specimen 10 continues. Yes.

  Furthermore, a measurement test was also conducted on the effect of lowering the oxidation-reduction potential by the slurry 5 for milk. Commercially available milk was used as the specimen 11, 230 ml of milk was placed in a 300 ml aluminum bottle, and a film pack sealed with 100 g of a transparent nylon film containing the slurry 5 was placed therein, and the change in ORP over time was measured. . The measurement results are shown in Table 5 (unit: mV).

  As shown in Table 5, the test piece 11 that is milk has a positive ORP value for both Horiba F53 and Takemura OM-68 at the start of measurement, but the ORP value is large after one day. It is a negative value. Further, when the ORP value was measured immediately after the specimen 11 was heated to about 40 ° C. and after 30 minutes, it was found that it also showed a negative value as shown in Table 5. Therefore, it was found that the slurry 5 has an effect of greatly reducing the oxidation-reduction potential (ORP) for milk.

  Furthermore, tap water is put into the beverage container 1 according to the present embodiment, and the ORP value of −120 mV (measured with Takemura OM-68) is replaced with a normal aluminum bottle, and after 16 hours have passed. When the ORP value was measured, although the tap water was exposed to air all the time in the aluminum bottle, the ORP values showed negative values of −50 mV for Takemura OM-68 and −19 mV for Horiba F53. As a result, a beverage whose ORP value shows a negative value by being accommodated in the beverage container 1 according to the present embodiment maintains the negative ORP value for a certain period of time even if it is transferred to another container. It has been found.

  As described above, the slurry 5 in which the fine powder of quartz diorite is gelled and dispersed in distilled water is brought into contact with various beverages through an organic synthetic resin container or a transparent nylon film, thereby various kinds of beverages. It has the effect of greatly reducing the redox potential (ORP) of beverages, and for many beverages the effect lasts for a long time. Therefore, it is possible to prevent the beverage from being oxidized and to lower the oxidation-reduction potential of the beverage simply by putting the favorite beverage in the beverage container 1 according to the present embodiment having the structure shown in FIG. Can improve the flavor of the beverage.

  Further, by tightening the cap 2A, it is convenient for storage and convenient for carrying the beverage container 1. The effect of lowering the redox potential of the beverage can be obtained even if the drinking mouth is opened without tightening the cap 2A. In addition, when the bottom 2D is detachable without being bonded and fixed to the body 2C, the bottom 2D can be used when the negative value of the ORP of the slurry 5 seems to have been reduced by use over many years. It is possible to remove the old slurry 5 from the space 4 and fill the space 4 with the new slurry 5.

  In this way, in the beverage container 1 according to the present embodiment, since the slurry 5 does not directly contact the beverage, there is no possibility of damaging the taste and flavor of the beverage, and drinking water or an existing beverage is used as the container. Oxidation can be prevented only by housing, and the oxidation-reduction potential can be lowered to improve the flavor of the beverage.

  As described above, the oxidation-reduction potential (ORP) of the beverage is greatly reduced even when the film pack in which the slurry 5 is wrapped in a transparent nylon film and sealed is put in various beverages in an aluminum bottle or a glass water bottle. Can do. This effect can be similarly obtained even when a film pack in which the slurry 5 is wrapped and sealed in various organic synthetic resin films other than the transparent nylon film is put in a beverage.

Accordingly, in this specification, “a beverage film pack that delays the oxidation of the beverage and lowers the oxidation-reduction potential, the organic synthetic resin film contains silicic acid (SiO ₂ ), aluminum (Al), iron Redox formed by gelling fine powder of quartz porphyry containing (Fe), calcium (Ca), magnesium (Mg), potassium (K), carbon (C), strontium (Sr), zinc (Zn) An invention of a “film pack for beverages characterized by containing and sealing a slurry of quartz porphyry gelled material having a negative potential” is also disclosed.

  Here, the fine powder of quartz porphyry used in the beverage film pack is preferably fine powder of quartz diorite. Moreover, it is preferable that the quantity of the slurry filled with the film pack for drinks exists in the range of 1/10 to 1/2 of a drink.

In this embodiment, as a slurry of silica porphyry gelled product having a negative oxidation-reduction potential, a gel having a negative oxidation-reduction potential formed by gelling fine powder of quartz diorite, which is a kind of quartz porphyry Although the case of using the slurry 5 of the chemical compound has been described, a slurry of a gelled product of other quartz porphyry may be used.
Moreover, in this Embodiment, although the case where the aluminum container 2 was used as a metal container was demonstrated, other metallic containers including a stainless steel container can also be used.

Furthermore, although the case where a PET (polyethylene terephthalate) bottle is used as the organic synthetic resin container has been described in the present embodiment, a container made of another organic synthetic resin may be used.
In the present embodiment, the case where the inner capacity of the PET bottle 3 as the organic synthetic resin container is set to about 1.7 times the capacity of the space 4 of the predetermined capacity has been described. The internal capacity may be in the range of 0.5 to 3.0 times the capacity of the space of the predetermined capacity, and more preferably in the range of 1.5 to 2.5 times.

  In practicing the present invention, the configuration, material, shape, component, material, size, connection relationship, and the like of other parts of the beverage container are not limited to the present embodiment.
