In addition, by providing an antibacterial glass container at such a position, when taking out the contents, the antibacterial glass and the contents are surely in contact with each other so that a predetermined amount of silver ions can be quickly and stably supplied. Can be released.
In addition, since the antibacterial glass contains a colorant as a compounding component, it is estimated that the antibacterial glass will be given an antibacterial property depending on how much the antibacterial glass has been reduced, or the antibacterial glass should be replaced visually. Can be judged.
In addition, in the case of such antibacterial glass, it is preferable to use a relatively large amount of B ₂ O ₃ as a raw material because it is easy to adjust the release of silver ions. It may be easy to do. However, when the antibacterial glass contains cobalt oxide or the like as a colorant, such a discoloration problem can be effectively avoided.
In addition, by controlling the shape of the antibacterial glass into a flat plate having a predetermined thickness in this way, the antibacterial glass is effectively prevented from agglomerating and the antibacterial property of the antibacterial glass against the contents is more easily controlled. be able to.

The container 1 is provided with the accommodating portion 11 of the antibacterial glass 50 as shown in FIG. 2 or 3 at the outlet 14a or inside of the main container 14, and a part of the accommodating portion 11 of the antibacterial glass 50. The container 1 is characterized in that a liquid passage portion 11b for the contents is provided.
Hereinafter, the container 1 and the container 11 of the antibacterial glass 50 will be described in more detail.

1. Containment container (1) form Although the form of the containment container 1 is not particularly limited, for example, a bottleneck type glass bottle, a rectangular glass bottle, a cylindrical shape corresponding to the use such as a cosmetic bottle or a medicinal bottle Examples include a glass bottle, an irregular glass bottle, a rectangular glass box, a cylindrical glass box, and an irregular glass box.
Therefore, for example, the configuration of the container 1 as shown in FIGS. 1, 4A to 4B, 5A to 5B, and the like is preferable.

First, in FIG. 1, the outer shape of the main container 14 for containing the contents is a vertically long rectangular parallelepiped, and includes a screw portion 14 a at the head and a groove portion 12 a that matches the screw portion 14 a. The container 1 has a substantially square lid 12.
FIG. 4A shows a storage container including an ellipsoidal main container 14 having a horizontal bottom portion 14d and a lid portion 12 adapted thereto.
In such a container 1, the contents and the antibacterial glass are easily in direct contact with each other so that a predetermined amount of silver ions can be stably released because the container 1 is basically placed horizontally. .
FIG. 4B shows the container 1 including a main container 14 having a rectangular parallelepiped body with a hemispherical bottom part 14e and a lid part 12 adapted thereto.
Since the main container 14 has the hemispherical bottom part 14e, the contents, the antibacterial glass, and the like are basically arranged with the lid part 12 facing down. , Can be more easily contacted directly, and a predetermined amount of silver ions can be stably released.

FIG. 5A shows a container 1 in which two main containers 14 and 14 ′ having a rectangular parallelepiped body are provided so as to face each other with a lid 12 that fits them.
If this container 1 is placed vertically, one of the two main containers 14 and 14 'is in direct contact with the contents and the antibacterial glass, so that a predetermined amount of silver ions can be stabilized. Can be released.
And when the contents in one accommodating part 14 and 14 'are consumed, by putting the other main container 14 and 14' below, the contents and antibacterial glass are either Can always be in contact.

FIG. 5B shows a main container 14 having an ellipsoidal body, a lid 12 adapted to the main container 14, and a part of the main container 14 and the lid 12 are fixed and placed downward. It is the storage container 1 provided with the base 13 for doing.
In such a storage container 1, since the storage container 1 is placed upside down by the pedestal 13, the contents and the antibacterial glass always come into contact with each other and stably release a predetermined amount of silver ions. be able to.

In addition, regarding the shape of the storage container 1 or its main container 14, it is also preferable to provide a thick part along the outer peripheral part or to provide a chamfered part on a part of the outer peripheral part.
The reason for this is that in such a container, a cured coating film is formed, and when viewed from the front of the container, the interference light is condensed at the thick part or chamfered part of the outer peripheral part, resulting in a clearer and more complex This is because a simple color can be observed.
In addition, it does not restrict | limit especially about the kind of glass which comprises such a storage container, Soda-lime glass, borosilicate glass, lead glass, phosphate glass, aluminosilicate glass, etc. are mentioned.

Moreover, although colorless and transparent glass can be used suitably as a material which comprises the storage container 1 or its main container 14, it is also preferable to use colored transparent glass and colored translucent glass.
The reason for this is that by using colored transparent glass or colored translucent glass, it is possible to add further arrangements to complex colors such as rainbow colors, iridescent colors, and scale patterns derived from interference light from the metal deposition layer. It is because it can do.

(2) Cap Further, in configuring the storage container 1, it is preferable to provide a cap 10 as shown in FIG. 2, and to provide a content outlet 10 a in the main container 14 on the top of the cap 10.
The reason for this is that, when the contents are taken out from the take-out port 10a, the antibacterial glass in the housing part 11 of the antibacterial glass 50 and the contents are surely brought into contact with each other, and a predetermined amount is obtained. This is because silver ions can be released quickly and stably.

In addition, the cap 10 is fitted into the first fitting portion 10 b fitted into the screw portion 14 a provided around the take-out port 14 a ′ of the container 1 and the first fitting portion 10 fitted into the accommodating portion 11 of the antibacterial glass 50. 2 fitting portions 10c.
This is because the cap 10 can be easily attached to the storage container 1 or the main container 14 by configuring in this way, and the second fitting part 10c is also used for the storage part 11 of the antibacterial glass 50. This is because it can be easily attached or removed simply by fitting it into the.
In addition, the contents can be retained between the first fitting part 10b and the second fitting part 10c in the cap 10, and when taking out the contents, the antibacterial glass and the contents This is because a predetermined amount of silver ions can be released quickly and stably.
In addition, as shown in FIG. 2, when the accommodating part 11 of the antibacterial glass 50 is attached, the second fitting part 10c that fits into the accommodating part 11 of the antibacterial glass 50 can be firmly press-fitted. It is preferable to provide a taper 10d with a taper at the tip.

Further, as a modification of the cap 10 and the antibacterial glass 50 accommodating portion 11, as shown in FIG. 3, the cap 10 is not shown in the shape of a cylinder without providing a taper 10 d, but the antimicrobial glass 50 accommodating portion 11. It is also preferable to provide a taper in the direction in which the tip widens or a non-slip unevenness at the tip of the tip.
Then, instead of providing a liquid passage location on the bottom portion 11c of the storage portion 11 of the antibacterial glass 50, a plurality of liquid passage locations 11b having different sizes such as lateral grooves are formed on the upper portion of the cylindrical portion 11a of the storage portion 11. It is preferable to provide it.
The reason for this is that the contents easily enter through the liquid passage portions 11b such as a plurality of lateral grooves having different sizes, and can easily come into contact with the antibacterial glass 50. This is because an object remains and can always come into contact with the antibacterial glass 50.

2. Antibacterial Glass Housing (1) Housing As shown in FIGS. 1 to 3, the antibacterial glass 50 has a housing 11 for providing the contents with antibacterial properties. The storage part 11 is provided in the storage container 1 (the outlet or the inside of the main container 14). And the liquid passage location 11b of the content is provided in a part of the accommodating part 11 of the antibacterial glass 50.
That is, by comprising in this way, antibacterial glass contacts the content accommodated in the main container 14 in the container 1 directly or indirectly, and a predetermined amount of silver ions is rapidly and for a long period of time. This is because even when the contents are released and the content does not contain a preservative or the like, predetermined antibacterial properties can be imparted.

In addition, it is preferable that the container 1 includes a cap 10 having a content outlet 10 a, and a container 11 for the antibacterial glass 50 is provided below the cap 10.
The reason for this is that, by configuring in this way, the accommodating portion 11 of the antibacterial glass 50 can be provided without significantly reducing the internal capacity of the container 1 with a cap. That is, in the container 1 with a cap, the content is rarely filled 100%, and the space 11 is used to provide the accommodating portion 11 for the antibacterial glass 50.

Moreover, regarding the shape of the accommodating part 11 of the antibacterial glass 50, as shown in FIG.
This reason is because the accommodating part 11 of the antibacterial glass 50 can be easily attached to the cap 10 etc. by comprising in this way. Moreover, if the shape of the accommodating part 11 of the antibacterial glass 50 is a cylindrical shape or a bag shape, the amount of the antibacterial glass 50 can be easily adjusted.
Furthermore, as shown to Fig.6 (a), it is preferable to lengthen accommodating part 11 'of antibacterial glass, and make it equal to the length of the main container 14, or make it 50 to 90% of length. That is, it is preferable to use a cylindrical accommodating portion 11 ′.
The reason for this is that the cylindrical storage portion 11 ′ can always come into contact with the contents stored in the main container 14 and quickly release a predetermined amount of silver ions. Moreover, since the capacity | capacitance of the accommodating part of antibacterial glass can be enlarged if it is cylindrical accommodating part 11 ', the accommodation amount and magnitude | size of antibacterial glass are adjusted, and predetermined amount silver ion is long. This is because it can be released over a period of time.
Moreover, as shown in FIG.6 (b), it is preferable to lengthen the accommodating part of antibacterial glass, and to make it thin toward the front-end | tip part. That is, it is preferable to use a tapered cylindrical accommodating portion 11 ″.
The reason for this is that if the container 11 ″ has a tapered cylindrical shape, the content stored in the main container 14 is always brought into contact with the contents stored in the main container 14 so that a predetermined amount of silver ions can be quickly obtained. This is because it can be released. Moreover, since it is thin toward the front-end | tip part, since the capacity | capacitance of the accommodating part of antibacterial glass can be made comparatively small, it is because the reduction | decrease in the capacity | capacitance of the main container 14 can be decreased.

Moreover, as shown to Fig.7 (a), as a deformation | transformation of the accommodating part 11 of the antibacterial glass 50, it is also preferable to suspend the accommodating part 11 of the antibacterial glass 50 via the connection part 20 below the cap.
The reason for this is that, by configuring in this way, the contents contained in the main container 14 can always be brought into contact with each other and a predetermined amount of silver ions can be quickly released. Moreover, it is because the elution amount of silver ions can be increased by shaking the main container 14.
Further, as shown in FIG. 7 (b), as a modification of the accommodating portion 11 of the antibacterial glass 50, a fibrous antibacterial glass 50 ′ made of antibacterial glass or a fibrous antibacterial coated with antibacterial glass. It is also preferable to attach the functional glass 50 ′ below the cap 10 and suspend them.
The reason for this is that, by configuring in this way, the contents contained in the main container 14 can always be brought into contact with each other and a predetermined amount of silver ions can be quickly released. Moreover, it is because the elution amount of silver ions can be increased by shaking the main container 14. Furthermore, with such a configuration, the decorativeness of the glass container can be improved.

Moreover, as a form of the storage container of the present invention, as shown in FIG. 8, the storage part 11 of the antibacterial glass 50 is preferably a spray container 1 ′ provided at the lower end of the liquid feeding tube 23.
The reason for this is that, by configuring in this way, the content can be effectively antibacterial even when the remaining amount of the content accommodated in the main container 14 '' becomes small, This is because the content containing a predetermined amount of silver ions can be reliably injected.
Therefore, this spray container 1 'can be used suitably also in the antibacterial spray for injecting antibacterial liquids, for example with respect to clothes.
In addition, in FIG. 8, only main container 14 '' and its inside are shown as sectional drawing.

(2) Antibacterial glass Although the planar shape of the antibacterial glass 50 accommodated in the accommodating part 11 is not particularly limited, as shown in FIGS. 9A to 9F, it is flat. A rectangular shape 50a, a polygonal shape 50b, a circular shape 50c, an elliptical shape 50d, an irregular shape 50e, a perforated shape 50f, and the like are preferable.
The reason for this is that the antibacterial glass is placed in a predetermined location by making it rectangular or perforated, and even if it is in direct contact with the contents, it is swept away from the specified location. This is because it can be effectively prevented from flowing out.
In addition, if the antibacterial glass is rectangular or the like, the antibacterial glass is less likely to agglomerate at the time of manufacture or use. This is because it becomes easier to control the environmental conditions .

Moreover, it is preferable to make the maximum diameter (t1) of antibacterial glass into the value within the range of 1-50 mm.
Here, the maximum diameter (t1) of the antibacterial glass is, for example, the length when a line is drawn at the maximum position in the shape of the antibacterial glass, as shown in FIGS. means.
The reason for this is that when the maximum diameter is less than 1 mm, when placed at a predetermined location and brought into direct contact with the contents, it may be pushed away or easily flow out of the predetermined location, or over a long period of time. This is because it may be difficult to release a predetermined concentration of silver ions, and it may become easy to aggregate during storage.
On the other hand, when the maximum diameter exceeds 50 mm, it becomes difficult to handle or it becomes difficult to manufacture stably.
Accordingly, the maximum diameter of the antibacterial glass is more preferably set to a value within the range of 8 to 30 mm, and further preferably set to a value within the range of 1 to 10 mm.
The maximum diameter (t1) of the antibacterial glass is the maximum diameter in the plane direction when the antibacterial glass is flat, for example, and the diameter of the sphere when it is spherical.

Moreover, when this antibacterial glass is flat form, let the thickness of an antibacterial glass be the value within the range of 0.1-10 mm .
The reason for this is that when the thickness of the antibacterial glass is less than 0.1 mm, it becomes difficult to release a predetermined concentration of silver ions, handling becomes difficult, and moreover, it is manufactured stably. This may be difficult. On the other hand, when the thickness of the antibacterial glass exceeds 10 mm, it is difficult to handle or to manufacture stably.
Therefore, when this antibacterial glass is flat, it is more preferable to set the thickness of the antibacterial glass to a value within the range of 0.5 to 8 mm, and further to a value within the range of 1 to 5 mm. preferable.
The maximum diameter and thickness of the antibacterial glass described above can be easily measured using, for example, an optical micrograph or a caliper.

Moreover, it is preferable to use the antimicrobial glass which consists of the following compositions regarding the kind of antimicrobial glass. That is, as raw materials, B ₂ O ₃ , SiO ₂ , Ag ₂ O, and alkali metal oxide are included, and the addition amount of B ₂ O ₃ is 30 to 60% by weight based on the total amount, It is preferable that the addition amount of SiO ₂ is 30 to 60% by weight, the addition amount of Ag ₂ O is 2 to 5% by weight, and the addition amount of alkali metal oxide is a value within the range of 5 to 10% by weight.
This is because an antibacterial glass having such a glass composition can directly contact the contents and quickly release a predetermined amount of silver ions.

Here, B ₂ O ₃ basically functions as a network-forming oxide. In addition, in the present invention, B ₂ O ₃ is also involved in the function of improving the transparency of antibacterial glass and the uniform release of silver ions. .
In addition, SiO ₂ functions as a network-modifying oxide in antibacterial glass and functions to prevent yellowing.
Ag ₂ O is an essential component in antibacterial glass, and excellent antibacterial properties can be expressed for a long time by dissolving the glass component and eluting silver ions.
Alkali metal oxides such as Na ₂ O and K ₂ O basically serve as a network-modifying oxide, while also exhibiting the function of improving the transparency of the antibacterial glass and the function of adjusting the melting temperature. be able to.
In addition, while adding an alkaline earth metal oxide, for example, MgO or CaO, the function as a network modification oxide can be achieved. On the other hand, as with the alkali metal oxide, the transparency improving function and melting of the antibacterial glass can be achieved. The temperature adjustment function can also be demonstrated.
Furthermore, by adding CeO ₂ , Al ₂ O ₃ or the like separately, it is possible to improve discoloration, transparency, or mechanical strength with respect to the electron beam.

On the other hand, when it contains Ag ₂ O, ZnO, CaO, B ₂ O ₃ and P ₂ O ₅ and the total amount is 100% by weight, it has excellent transparency, antibacterial properties, and dispersibility. ₂ O content in the range of 0.2 to 5% by weight, ZnO content in the range of 1 to 50% by weight, CaO content in the range of 0.1 to 15% by weight The content of B ₂ O ₃ is set to a value within the range of 0.1 to 15% by weight, and the content of P ₂ O ₅ is set to a value within the range of 30 to 80% by weight, and ZnO / CaO An antibacterial glass having a weight ratio of 1.1 to 15 is also preferable.
Furthermore, although ZnO is not substantially contained, when Ag ₂ O, CaO, B ₂ O ₃ and P ₂ O ₅ are included and the total amount is 100% by weight, the content of Ag ₂ O is 0. A value in the range of 2 to 5% by weight, a CaO content in the range of 15 to 50% by weight, a B ₂ O ₃ content in the range of 0.1 to 15% by weight, and An antibacterial glass having a P ₂ O ₅ content in the range of 30 to 80% by weight and a CaO / Ag ₂ O weight ratio in the range of 5 to 15 is also preferable.

Moreover, it is preferable to make the elution amount of the silver ion in antibacterial glass into the value within the range of 0.001-100 mgmg / (g * 24Hrs).
This is because when the elution amount of such silver ions is less than 0.001 mg / (g · 24 Hrs), it is difficult to quickly release silver ions of a predetermined concentration when brought into direct contact with water. This is because it may become.
On the other hand, when the elution amount of such silver ions exceeds 100 mg / (g · 24 Hrs), it becomes difficult to release silver ions at a predetermined concentration over a long period of time, handling becomes difficult, or stable production. It is because it becomes difficult to do.
Therefore, it is more preferable to set the elution amount of silver ions in the antibacterial glass to a value in the range of 0.05 to 50 mg / (g · 24 Hrs), and a value in the range of 1 to 10 mg / (g · 24 Hrs). More preferably.
In addition, the elution amount of silver ions in the antibacterial glass can be measured according to the measurement method described in Example 1 described later.

Moreover, it is also preferable to use mixed antibacterial glass containing antibacterial glass that emits silver ions at a predetermined concentration and non-antibacterial glass that does not release silver ions, as the antibacterial glass housed in the housing unit.
This is because by using the mixed antibacterial glass containing the non-antibacterial glass, aggregation of the antibacterial glasses can be effectively prevented and a predetermined antibacterial effect can be exhibited over a long period of time.
Further, by adding a predetermined amount of non-antibacterial glass, even if discoloration of the antibacterial glass occurs, visual change in appearance can be reduced.
In addition, it is preferable to make the addition amount of non-antibacterial glass into the value within the range of 10-3000 weight part with respect to 100 weight part of antibacterial glass.
The reason for this is that, with such an added amount of non-antibacterial glass, the predetermined antibacterial property as a mixed antibacterial glass can be expressed and the weight of the entire mixed antibacterial glass can be easily controlled. This is because it can.

In addition, a colorant is added to the antibacterial glass as a blending component, and the addition amount of the colorant is set to a value within the range of 0.001 to 0.5% by weight with respect to the total amount. preferable.
The reason for this is that the antibacterial glass is presumed to be given from the reduction of the antibacterial glass, or the replacement period of the antibacterial glass is visually determined. It is because it can do.
Further, with this configuration, even when a relatively large amount of B ₂ O ₃ that is likely to be discolored is used, such a discoloration problem is effectively avoided by including cobalt oxide or the like as a colorant. Because it can.
The colorant is preferably at least one compound selected from the group consisting of cobalt oxide, copper oxide, chromium oxide, nickel oxide, manganese oxide, neodymium oxide, erbium oxide, and cerium oxide. And especially since it can provide the anti-discoloration effect with respect to antibacterial glass specifically, and it is excellent in visibility, it is preferable to add cobalt oxide to make blue antibacterial glass.

(3) Coating member or additive Complex-forming compound capable of forming a complex with silver ions, such as ammonium sulfate, ammonium nitrate, ammonium chloride, sodium thiosulfate, ammonium sulfide, ethylenediaminetetraacetic acid (EDTA), ammonium acetate, It is preferable to add one kind alone or a combination of two or more kinds such as ammonium chlorate and ammonium phosphate.
This is because discoloration and coloring of the antibacterial glass can be remarkably prevented by adding such a complex-forming compound.
Note that even if the atmosphere is a strong alkali, for example, a pH value of 10 or more, a complex can be easily formed with silver ions to prevent coloring, so that ammonium sulfate, ammonium nitrate, ammonium chloride, and More preferably, at least one compound selected from the group consisting of sodium thiosulfate is used.

Moreover, it is preferable to make the addition amount of a complex formation compound into the value within the range of 0.01-30 weight% with respect to the whole quantity.
This is because when the amount of the complex-forming compound added is less than 0.01% by weight, it may be difficult to effectively prevent discoloration. On the other hand, when the addition amount of the complex-forming compound exceeds 30% by weight, the antibacterial property of the antibacterial glass may be lowered or it may be difficult to mix uniformly.
Therefore, since the balance between discoloration resistance and antibacterial properties in the antibacterial glass is more preferable, the addition amount of the complex-forming compound is a value within the range of 0.1 to 20% by weight with respect to the total amount. It is more preferable to set the value within a range of 0.5 to 10% by weight.

Moreover, it is also preferable that the coating member has a form in which an antibacterial glass is coated with inorganic and / or organic particles.
The reason for this is that by constituting in this way, it is possible to easily control the elution rate of silver ions and to improve the anti-aggregation property of the antibacterial glass.
In addition, as particles covering the antibacterial glass, titanium oxide, silicon oxide, colloidal silica, zinc oxide, tin oxide, lead oxide, white carbon, acrylic particles, styrene particles, polycarbonate particles, etc. A combination is preferred.
Further, the method for coating the antibacterial glass with the particles is not particularly limited. For example, the antibacterial glass and the particles are uniformly mixed and then heated at a temperature of 600 to 1200 ° C. to be fused to the glass. Or it is preferable to fix through a binder.

Also, for antibacterial glass, for the purpose of preventing oxidation or coloring, an antioxidant such as a surfactant as a dispersant, stearic acid, myristic acid, sodium stearate, or a silane coupling agent. It is preferable to add pigments or dyes as colorants such as hindered phenol compounds and hindered amine compounds.
In addition, it is preferable to determine the addition amount of these additives in consideration of the addition effect and the like. For example, each of the additives is set to a value within a range of 0.01 to 30% by weight with respect to the total amount. More preferred.

(4) The production method the raw material, and B ₂ O _3,. 30 to the SiO _2, and Ag ₂ O, and an alkali metal oxide, as well as using, based on the total amount, the amount of B ₂ O ₃ 60 wt%, SiO ₂ addition amount is 30 to 60 wt%, Ag ₂ O addition amount is 2 to 5 wt%, and alkali metal oxide addition amount is 5 to 10 wt%. As described above, the mixture was stirred using a universal mixer at a rotational speed of 250 rpm for 30 minutes until it was uniformly mixed. Next, using a melting furnace, as an example, the glass raw material is heated at 1280 ° C. for 3 hours and a half to prepare a glass melt, which is cooled and crushed with a ball mill, a crusher, etc. Glass.
The heating conditions in the melting furnace can be changed as appropriate according to the type of raw materials and the blending ratio.

Next, using a glass melting furnace, the glass raw material was heated under the conditions of 1280 ° C. and 3 hours and a half to prepare a molten glass.

(2) Forming process The molten glass taken out from the glass melting furnace is introduced into the insertion port of the production apparatus, and is a flat antibacterial glass (rectangular small piece, maximum diameter (t1): 8 mm, which can be cut continuously with chocolate). Thickness (t2): 3 mm).
This was made into a polyhedral antibacterial glass having an average particle diameter of 5 mm using a ball mill.

2. Evaluation of antibacterial glass (1) Silver ion elution evaluation 10 g of the obtained antibacterial glass was immersed in 100 ml of distilled water (20 ° C.) and shaken for 24 hours using a shaker. The silver ion eluate was separated using a centrifuge and then filtered using a filter paper (5C) to obtain a measurement sample. Next, the silver ions in the measurement sample were measured by ICP emission spectroscopy, and the silver ion elution amount (mg / (g · 24 Hrs)) in the antibacterial glass was calculated.

(2) Evaluation of antibacterial properties 1 g of the obtained antibacterial glass was put into a storage unit provided in a storage container (glass container, capacity: 300 ml) in the form shown in FIG.
