Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for preventing alteration of beverages such as drinking water and juice which can be preserved without alteration.

[0002]

2. Description of the Related Art Conventionally, beverages such as tap water have been completely sterilized and sterilized with chlorine in order to eliminate infection by disease-causing microorganisms. Further, conventionally, beverages such as milk and juice, milk beverages, soft drinks, cans, and bottles and packs have been used as soon as possible to prevent spoilage after opening.

[0003]

The conventional tap water is sterilized and disinfected and is safe to use for drinking. However, if the amount of combined residual chlorine in tap water is large, a peculiar chlorinated odor is generated and water is generated. In addition to the problem that the water becomes unsatisfactory, when tap water is put in a container and stored at room temperature, the water is altered by falling bacteria that drop when the tap water is put in the container. Further, there is a problem that a can, a milk beverage such as milk or juice after opening a bottle or a pack, and fallen bacteria falling when a soft drink is put in the container are deteriorated. Furthermore, if most beverages other than tap water, milk drinks, and soft drinks are put in a container and stored at room temperature to some extent, most of them will always be altered.

The present invention has been made to solve the above-mentioned conventional problems, and prevents deterioration of a beverage which does not deteriorate even if the beverage is stored at room temperature for a long period of time and has a deodorizing effect. It is intended to provide a container.

[0005]

According to the present invention, 3 to 10% by weight of a composite ceramic powder obtained by mixing magnesia and silica, or magnesia, silica and zinc oxide.
The above-mentioned problems were solved by adopting a means of adding and mixing with a polymer that transmits far infrared rays and molding.

[0006]

According to the present invention having the above structure, far infrared rays are radiated to beverages from the composite ceramic having deodorant and antibacterial properties contained in the polymer which transmits far infrared rays.

[0007]

EXAMPLE A container A for preventing alteration of a beverage according to the present invention is a polymer 2 which emits far infrared rays and has a far infrared ray transmitting property which is a base material of a composite ceramic powder 1 having both deodorizing property and antibacterial property. It is molded by adding and mixing with.

Among the single-component ceramics, zeolite and Otaniishi have hitherto been known to have a deodorizing effect, and magnesia has an antibacterial rate close to 100% against Escherichia coli and Staphylococcus. It is known that it has excellent antibacterial properties, but has no deodorizing effect on ammonia and hydrogen sulfide.

From the above viewpoints, the present inventors individually measured far-infrared emissivity, deodorizing rate and antibacterial rate of a single component ceramic, and as shown in Table 1, magnesia, silica and zinc oxide were used. It was found that the three types were excellent in far infrared radiation rate, deodorization rate and antibacterial rate.

[0010]

[Table 1]

From the results shown in Table 1, it was found that magnesia has an antibacterial rate close to 100% against both Escherichia coli and S. aureus. Further, silica has a deodorizing rate of 100% with respect to hydrogen sulfide and 93% with respect to ammonia, but has almost no antibacterial property, and zinc oxide has a deodorizing rate of 100% with respect to hydrogen sulfide. It was found that ammonia has almost no deodorizing property and little antibacterial property.

From the above results, it is considered that ceramics having deodorizing property and antibacterial property can be obtained by mixing the ceramics having excellent deodorizing ratio and the ceramic having excellent antibacterial ratio to form a composite ceramic. Magnesia, which has an antibacterial rate close to 100% against any of the staphylococci, is adopted as the base material of the composite ceramics to be added and mixed into the polymer forming the alteration preventing container of the beverage of the present invention. ~ 55 wt% magnesia, 45-55 wt% silica as a mixture
Or 50 to 50% by weight of magnesia as a base material and 25 to 40 of silica as a mixing material.
By mixing wt% and zinc oxide in a proportion of 25 to 40 wt%, a composite ceramic having a good far-infrared emissivity and having both deodorizing property and antibacterial property was obtained.

The composite ceramics can be obtained by uniformly mixing and firing magnesia and silica, or powders of magnesia, silica and zinc oxide. Table 2 shows the results obtained by measuring the far-infrared emissivity, the deodorizing rate, and the antibacterial rate of the composite ceramics obtained with different mixing ratios.

[0014]

[Table 2]

From the results shown in Table 2 above, it was found that the composite ceramics obtained by mixing magnesia with silica or magnesia with silica and zinc oxide had an extremely high ratio in far-infrared radiation, deodorizing property and antibacterial property.

Any one of the above composite ceramics is added to a polymer made of polyethylene, vinyl chloride, or polyamide as a base material, preferably in an amount of 3 to 10% by weight, particularly preferably 5% by weight, and mixed into a predetermined shape. The beverage container A is formed by molding.

In order to allow far infrared rays emitted from the composite ceramics to be transmitted and emitted to the outside without being absorbed, to exert a deodorizing and antibacterial action, the polyethylene, vinyl chloride, or polyamide having high far infrared ray permeability is used. A polymer composed of either one was adopted.

Table 3 shows the results of measuring the characteristics of a container molded by adding 5% by weight of the composite ceramics to each of the polymers as a base material and mixing them.

[0019]

[Table 3]

The measured values shown in Table 3 show a relatively high deodorizing rate and antibacterial rate in all cases.

The deodorizing mechanism of the composite ceramics added to the polymer is generally a decomposition method of the composite ceramics. Ammonia (H2S) and hydrogen sulfide (NH3) are decomposed into their respective single components, lose their functions as ammonia and hydrogen sulfide, and are deodorized.

In addition, the antibacterial mechanism by the composite ceramics added and mixed in the polymer is such that the inorganic materials such as magnesia, silica, zinc oxide, etc., which are the materials of the composite ceramics, generate cations by light, and generally, the surface layer of bacteria. Is an anion. The surface layer of bacteria is destroyed by the cations generated from the inorganic substance, and the function of the microorganism is lost and it is sterilized.

Then, among the molded products shown in Table 3 above, a comparison was made between the container of the present invention formed of a molded product in which the polymer is vinyl chloride and a container which has been generally used in the past, in comparison with the growth state of microorganisms in drinking water. The table is shown as Table 4.

[0024]

[Table 4]

[0025] Generally, drinking water is 100 / ml of general bacteria.
In the following, the standard is that no coliform bacteria are detected, but judging from the comparison table of the growth of microorganisms in Table 4 above, in the case of using a general-purpose container, all of the above standard values were exceeded after 3 days of lapse of time. , Cannot be served as drinking water.

On the other hand, when the container of the present invention was used, the number of general bacteria was 3 / ml and coliform bacteria were not detected even after 3 days, and the drinking water was below the above standard value. It is possible to serve as.

[0027]

EFFECTS OF THE INVENTION Since the present invention is as described above, the far infrared rays are radiated to the beverage from the composite ceramics having the deodorant and antibacterial properties contained in the polymer which transmits the far infrared rays, and the far infrared rays are radiated to the beverage. Deodorization of odor by ammonia, hydrogen sulfide, etc., and antibacterial against Escherichia coli and staphylococcus can be achieved, and it can be preserved at room temperature for a long time without deterioration.
