Description

Antibacterial pouch {ANTIBACTERIAL POUCH}

The present invention relates to an antibacterial pouch, and more particularly, includes a mixed powder embedded in a powder bag having a pore structure, and exhibits high antimicrobial properties to prevent the propagation of bacteria, as well as to exhibit deodorization and dehumidification effects, so that it can be used hygienically. It relates to an antibacterial pouch.

Antibacterial refers to inhibiting and preventing the reproduction of microorganisms, and a substance having such an effect is referred to as an antibacterial substance or an antibacterial agent. In a similar concept, sterilization or sterilization means radically killing microorganisms.

The fungicide is known to exhibit excellent activity in removing all propagated microorganisms, but the effect is not sustained, whereas the antimicrobial substance is known to exhibit a relatively lasting effect.

Since both humidity and temperature are involved in the growth and propagation of microorganisms, when an antibacterial substance is included in a desiccant that absorbs moisture in the air, it is expected to effectively prevent the propagation of microorganisms and prevent diseases caused by microbial infection.

Antibacterial substances added to prevent bacterial growth can be largely classified into organic antibacterial substances and inorganic antibacterial substances. First, the organic antimicrobial substance mainly uses the effect of the elution of the drug, and acts closer to the antibacterial to prevent the formation of a colony of bacteria rather than sterilization. The biggest advantage of using an organic antimicrobial material is that the object to be sterilized is exposed to the surface quickly so that it immediately prevents the propagation of bacteria, and it has the advantage of being relatively inexpensive.

However, not only the durability of the product is weak due to the rapid dissolution due to the rapid migration of the organic antibacterial substance, and if high temperature work is required during the manufacturing process of the product, it cannot be applied due to thermal decomposition of the organic antibacterial substance. There is a problem such as harmfulness to, and in particular, it has a disadvantage that it cannot be used where toxicity problems are raised due to the fluidity and solubility of organic matter.

In contrast, inorganic antimicrobial substances are products made by replacing silver, zinc, copper, etc., which are metal ions that have an antibacterial action on inorganic substances, and are currently used in various fields such as plastic products, paper, and fibers. These inorganic antibacterial substances have high human safety, no resistant bacteria appear, and the duration of antibacterial is almost semi-permanent, so its use area is expanding.

However, the inorganic antibacterial material has a disadvantage in that the antibacterial activity is significantly lower than that of the organic antibacterial material, and the function appears at a very high concentration even if it has an antibacterial effect.

Accordingly, there is a need for an antibacterial substance and an antibacterial product using the antibacterial substance, which are harmless to the human body and the environment, and exhibit antibacterial, deodorant, and dehumidifying effects at the same time to exhibit complex antibacterial activity.

Republic of Korea Patent Publication No. 10-2016-0022515

The present invention is to solve the above problems, and to provide an antibacterial pouch that can be used hygienically by not only preventing the propagation of bacteria by showing high antibacterial properties, but also exhibiting deodorizing and dehumidifying effects.

Hereinafter, embodiments and examples of the present application will be described in detail with reference to the accompanying drawings. However, it may not be limited to these embodiments and examples and drawings of the present application.

One aspect of the present application, a breathable powder bag having a pore structure; And it provides an antibacterial pouch comprising a mixed powder including zinc oxide, alum, and ceramic powder contained in the powder bag.

Hereinafter, an antibacterial pouch according to an embodiment of the present application may be described through according to an exemplary embodiment of the present application with reference to FIG. 1.

First, the antibacterial pouch 100 according to an embodiment of the present application includes a mixed powder 102 embedded in a breathable powder bag 101 having a pore structure.

In one embodiment, the mixed powder includes zinc oxide, alum, and ceramic powder, and the ceramic powder is selected from the group consisting of diatomaceous earth powder, zeolite powder, bentonite powder, ceresite powder, and combinations thereof. It may contain more than one. Preferably, the ceramic powder may include diatomaceous earth powder and bentonite powder.

In one embodiment, the zinc oxide, alum, diatomaceous earth powder, and bentonite powder included in the mixed powder have different powder sizes, and thus may selectively pass through the powder bag having the pore structure. Specifically, the zinc oxide, alum, and bentonite powders are smaller than the pore size of the powder bag and may pass through the powder bag to be discharged to the outside, and the silicate powder is larger than the pore size of the powder bag. It may not pass and may be continuously built into the inside of the powder bag.

In one embodiment, the powder bag may be made of a non-woven fabric or a mesh fabric through which zinc oxide, alum, and bentonite powders can pass without passing through the diatomaceous earth powder, and the pore size of the powder bag may be about 50 μm or less. . As the pore size of the powder bag is about 50 μm or less, the powder having a size larger than the pore size of the powder bag does not pass through the powder bag and is continuously embedded in the powder bag, and is larger than the pore size of the powder bag. The small-sized powder may be continuously discharged little by little through the powder bag. Specifically, the pore size of the powder bag is about 1 to about 50 μm, about 1 to about 40 μm, about 1 to about 30 μm, about 1 to about 20 μm, about 1 to about 10 μm, about 10 to about 50 μm , About 10 to about 40 μm, about 10 to about 30 μm, about 10 to about 20 μm, about 20 to about 50 μm, about 20 to about 40 μm, about 20 to about 30 μm, about 30 to about 50 μm, It may be about 30 to about 40 μm, or about 40 to about 50 μm, but is not limited thereto.

In one embodiment, the powder bag may preferably be made of a non-woven fabric, and the non-woven fabric may be used without limitation, as long as it has a breathable structure having a pore size of about 50 μm or less. In addition, the powder bag made of the non-woven fabric may be sealed with thermal bonding, thermal bonding, high frequency bonding, sewing finish, or string.

_{In one embodiment, the diatomaceous earth powder contained in the powder bag is a natural mineral comprising silicic acid (SiO 2} ), alumina, and iron oxide as major constituents, as single-celled organisms of diatoms, which are phytoplankton, are deposited and rocked. .

In one embodiment, the antimicrobial pouch includes diatomaceous earth powder, thereby absorbing moisture to remove moisture, and absorbing volatile organic compounds and odors in the air to exhibit a deodorizing effect. For example, the diatomaceous earth powder that has a size larger than the pore size of the powder bag and does not pass through the powder bag contains fine pores, so that when the powder bag is wet by water or exposed to a humid environment, it absorbs moisture. By doing so, moisture can be removed, and volatile organic compounds and odors in the air can be absorbed to exhibit a deodorizing effect.

In one embodiment, the size of the diatomaceous earth powder may range from about 50 to about 100 μm. When the size of the diatomaceous earth powder is less than about 50 μm, the diatomaceous earth powder may pass through the powder bag and leak out, and when the size of the diatomaceous earth powder exceeds about 100 μm, the antibacterial pouch exhibits a rough texture and thus the preference may decrease The size of the diatomaceous earth powder is preferably about 50 μm to about 100 μm.

In one embodiment, the diatomaceous earth powder may be included in an amount of about 30 to about 60 parts by weight based on 100 parts by weight of the total mixed powder. If the diatomaceous earth powder is included in less than about 30 parts by weight of the total 100 parts by weight of the mixed powder, the dehumidification and deodorization effect may not be sufficiently exhibited, and when it exceeds about 60 parts by weight, other constituents other than the diatomaceous earth powder The weight ratio may be relatively reduced, and thus the effect may be reduced.

In one embodiment, the bentonite powder contained in the powder bag is one of a layered silicate mineral, which is produced by conversion of volcanic ash, and is mainly composed of smectite mineral.

In one embodiment, the antibacterial pouch may exhibit antibacterial, deodorant, and dehumidifying effects by including bentonite powder. For example, since bentonite has excellent swelling degree and adsorption performance, it can effectively absorb and remove moisture, volatile organic compounds, and odors present in the air.

In one embodiment, the size of the bentonite powder may be adjusted through a grinder, for example, it may mean that the size is adjusted to a size ranging from about 1 to about 30 μm. The bentonite powder has a particle size in the range of about 1 to about 30 μm, so that it has a size smaller than the pores of the powder bag having a size of about 50 μm or less, and passes through the outside through an action such as kneading or shaking the powder bag and continuously Accordingly, when the powder bag is touched with a wet hand or the like, the moisture that has penetrated into the powder bag is absorbed by the diatomaceous earth powder contained in the powder bag, and the moisture outside the powder bag is discharged. It may be absorbed by bentonite powder.

In one embodiment, the bentonite powder may be included in an amount of about 20 to about 40 parts by weight based on 100 parts by weight of the total mixed powder. If the bentonite powder is included in less than about 20 parts by weight relative to the total 100 parts by weight of the mixed powder, moisture outside the powder bag may not be properly absorbed, and if it exceeds about 40 parts by weight, the bentonite powder leaks out at once. This can happen.

In one embodiment, the antibacterial pouch may exhibit an antibacterial effect by including zinc oxide powder. For example, the zinc oxide may have an effect of improving and treating skin problems caused by viruses and fungi by binding to bacterial cell membranes and membrane proteins to destroy the structure and to lose activity.

In one embodiment, the zinc oxide powder may have a size in the range of about 200 nm to about 1 μm, and thus may pass through the pore structure of the powder bag and be discharged to the outside. For example, the zinc oxide powder has a size smaller than the pores of a powder bag having a size of about 50 μm or less, and can be continuously discharged by passing outside through actions such as kneading or shaking the powder bag. When the powder bag is touched with a wet hand, etc., moisture penetrating into the powder bag is absorbed by the diatomaceous earth powder contained in the powder bag, and viruses or bacteria remaining in the hand are killed by the antibacterial effect of the zinc oxide. It can be.

If the size of the zinc oxide powder is less than about 200 nm, the size of the zinc oxide powder is too small, and the zinc oxide powder is not continuously discharged and leaks out at a time. It may not pass through the pore.

In one embodiment, the zinc oxide powder may be included in an amount of about 10 to about 20 parts by weight based on 100 parts by weight of the total mixed powder. If the zinc oxide powder is included in an amount of less than about 10 parts by weight relative to the total 100 parts by weight of the mixed powder, the antibacterial effect may decrease, and when it exceeds about 20 parts by weight, the zinc oxide powder may leak out at once.

In one embodiment, the alum is a complex salt of aluminum sulfate and a monovalent metal sulfate, and may exert an antibacterial effect by destroying the cell walls of bacteria through dehydration.

In one embodiment, the size of the alum may be adjusted through a grinder, for example, it may mean that the alum is adjusted to a size in the range of about 1 to about 10 μm. Since the alum has a particle size in the range of about 1 to about 10 μm, it has a size smaller than the pores of the powder bag having a size of about 50 μm or less, so that the alum passes out through actions such as kneading or shaking the powder bag and continuously Accordingly, when the powder bag is touched with a wet hand or the like, the moisture that has penetrated into the powder bag is absorbed by the diatomaceous earth powder contained in the powder bag, and bacteria remaining in the hand are absorbed by the alum. It may be killed by its antibacterial effect.

In one embodiment, the alum may be included in an amount of about 5 to about 10 parts by weight based on 100 parts by weight of the total mixed powder. If the alum is included in an amount of less than about 5 parts by weight relative to the total 100 parts by weight of the mixed powder, the antibacterial effect may decrease, and if it exceeds about 10 parts by weight, the alum powder may leak out at once.

In one embodiment, the mixed powder may further include aluminum hydroxide powder having a size of about 1 to about 10 μm. The aluminum hydroxide may function as an antibacterial agent capable of improving the antibacterial properties of the antibacterial pouch. For example, it is preferable to use boehmite (AlO(OH)) as the aluminum hydroxide, and the boehmite is γ-boehmite, α-boehmite, and pseudo-boehmite (Pseudo-Boehmite). I can.

In one embodiment, the aluminum hydroxide powder may be included in an amount of about 1 to about 5 parts by weight based on 100 parts by weight of the mixed powder. If the content of the aluminum hydroxide is less than about 1 part by weight, it is difficult to express the antibacterial effect to be achieved, and if it exceeds about 5 parts by weight, there is a concern that the miscibility with other components may be inhibited.

In one embodiment, the mixed powder may exert an effect of absorbing moisture that has permeated into the powder bag by adding rice husk powder pulverized to a size of about 100 to about 500 μm.

In one embodiment, the rice husk powder may be prepared by pulverizing after drying and sterilizing in a sintering machine. For example, rice husks are put in a sintering machine and in a temperature range of about 100°C to about 150°C, about 10 to about It may be calcined for 30 minutes, dried and sterilized, and then pulverized.

In one embodiment, the rice husk powder may be included in an amount of about 1 to about 5 parts by weight based on 100 parts by weight of the mixed powder, and if it is included in less than about 1 part by weight, moisture that has penetrated into the powder bag is not sufficiently absorbed. Bacteria may occur, and if it exceeds about 5 parts by weight, there is a concern that the miscibility with other ingredients may be impaired.

In one embodiment, the mixed powder may further include a natural pest repellent. The natural pest repellent may be one or more ethanol extracts selected from lemon eucalyptus, citronella, diremon, geraniol, citral, nerol, and eucalyptus, and preferably may be an ethanol extract of lemon eucalyptus.

Lemon eucalyptus is a plant of gilding sheep and evergreen shrubs, and is native to Australia. According to the Centers for Disease Control and Prevention, lemon eucalyptus oil is the only alternative to DEET, a pest repellent. In one embodiment, by including an extract of a natural pest repellent such as lemon eucalyptus as a constituent of the mixed powder, there is an effect of achieving a simple and safe insect repellent effect when using the final product prepared therefrom. On the other hand, the natural pest repellent is preferably contained in about 1 to about 5 parts by weight based on the total 100 parts by weight of the mixed powder. If the natural pest repellent is less than about 5 parts by weight, it is difficult to achieve the desired insect repellent effect, and if it exceeds about 5 parts by weight, mixing with other components may be inhibited, resulting in poor moldability and durability.
