Description

TECHNICAL FIELD The present invention relates to an antibacterial interior decoration utilizing the antibacterial and antiviral action of copper.

It has long been known that copper has antibacterial and antiviral effects. The mechanism is thought to be that copper ions perforate the envelope membrane of the virus and that free radicals produced by copper ions degrade genetic material. Also, according to a research team at the National Institutes of Health (NHI) in the United States, the new coronavirus can survive for 72 hours on plastic and stainless steel surfaces, and 24 hours on cardboard, but on copper surfaces. It is said that it is 4 hours, and it has been confirmed that copper has an antiviral effect against the new coronavirus.

Antibacterial materials utilizing such antibacterial/antiviral effects have also been proposed in the past, and Patent Document 1 discloses that very fine copper alloy powder with a particle size of 1 nm to 1 μm is dispersed on the surface of an article. Have been described. Further, Patent Document 2 describes an antibacterial fabric using composite fibers containing copper alloy yarns. Patent Document 3 discloses an antibacterial composition in which copper powder is mixed with portland cement. However, in order to increase the surface area of these conventional antibacterial/antiviral materials, copper is processed into fine powders or fine fibers, which causes the problem of high manufacturing costs.

Moreover, in Patent Document 3, by spraying antibacterial material or creating artificial flowers with resin or fiber into which antibacterial material is kneaded, and placing them indoors, they exhibit deodorant and antibacterial effects as well as aesthetic effects as interior decorations. is described. However, it is inevitable that the deodorizing effect and the antibacterial effect thereof gradually decrease with the lapse of time.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-described conventional problems, to provide an interior decoration that can be manufactured at a lower cost than conventional ones and that has excellent antibacterial and antiviral effects that last long. is.

The present inventor is in the business of processing copper products, and paid attention to a large amount of shavings generated when cutting a copper material with a lathe or a milling machine. This shavings have been disposed of as waste until now, but I came to the idea that it would be possible to manufacture interior decorations at extremely low cost using the antibacterial and antiviral properties of copper.

The present invention has been made based on the above findings, and includes a container with an open top, an aggregate of copper shavings filled in the container, and a copper shavings placed on the upper surface of the aggregate of shavings. and a decorative member.

The shavings of the copper material are preferably spiral shavings generated when the copper material is cut with a lathe or a milling machine. Moreover, it is also possible to adopt a structure in which a tray is provided under the container. Also, the copper material can be pure copper or a copper alloy.

The upholstery of the present invention can be manufactured at a very low cost because it uses shavings generated when cutting copper material, which has conventionally been disposed of as waste, as a raw material. The shavings are fine and spiral and thus have a large surface area. Moreover, by filling the shavings into the inside of the container whose top is open, the shavings are prevented from scattering while securing the contact area with the air, and even when installed indoors, the copper fine pieces are scattered. never.

When the interior decoration of the present invention is placed indoors, when bacteria and viruses floating in the air in the room come into contact with the surface of shavings made of copper material, the activity of the bacteria and viruses is reduced by the antibacterial and antiviral action of the copper ions. can be done. In addition, since copper has an anti-mold effect and a deodorant function, it can suppress the mold that is generated in the room and deodorize the room. Moreover, the effect of the air purifier of the present invention lasts semipermanently and does not deteriorate. Furthermore, since the air purifying device of the present invention has a decorative member arranged on the upper surface of the aggregate of shavings, it also has a function as an indoor decoration. , is of high practical value.

Embodiments of the present invention are described below.
FIG. 1 is an external perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view thereof. Reference numeral 10 denotes a container having an open top, and the interior thereof is filled with shavings 20 made of a copper material.

The material of the container 10 is not particularly limited, and any material such as resin, metal, ceramics, glass, or paper can be used. Alternatively, a metal net, a punching metal, a perforated resin plate, or the like having holes through which air can flow may be used. However, it is preferable to keep the size of the hole small so that the shavings 20 of the copper material do not fly out.

The shape of the container 10 is also not particularly limited, and may be a bowl-like shape as shown in the drawing, or a dish-like shape with a shallow depth. Furthermore, it can be in any shape such as a tumbler shape, a cup shape with a handle, or a cup shape with legs. However, in either case, the upper surface is left open so that the air in the room and the shavings 20 made of copper material can come into contact with each other.

In addition, in this embodiment, a saucer 11 is arranged at the bottom of the container 10 . Although the tray 11 is not essential, it can receive fine pieces of the copper material shavings 20 spilled from the container 10 so as not to scatter in the room.

The shavings 20 of the copper material are shavings generated when the copper material is cut with a lathe or a milling machine. Many of these shavings 20 have a fine spiral shape as shown in the figure, and since minute spaces are formed not only on the surface but also inside, the area of contact with the air in the room becomes very large. The shavings 20 shown are generated when milling a copper material. It should be noted that lathe shavings 20 are also spiral, but the individual lengths are often longer than those produced by a milling machine. Even if it mixes and uses both, it does not interfere. Depending on processing conditions, the outer diameter of the spiral is about 1 to 10 mm.

The copper material may be pure copper or a copper alloy. Various copper alloy shavings 20 may be utilized, such as, for example, alumina dispersion strengthened copper, silver-containing copper, beryllium-containing copper, chromium-zirconium-containing copper, and cobalt-containing copper. These copper materials are widely used as industrial materials and generate a large amount of shavings 20, so they are readily available. Although many of the alloy components do not have antibacterial/antiviral effects, they do not interfere with the antibacterial/antiviral effects of copper.

In the interior decoration of the present invention, the decoration 30 is arranged on the upper surface of the collection of shavings 20 . In this embodiment, an aggregate of shavings 20 is made to look like the ground or the surface of water, and an artificial flower as a decorative body 30 is arranged thereon. Since the artificial flower has petals 32, leaves 33, etc. attached to the upper portion of a shaft 31, the shaft portion 31 is inserted into the aggregate of the shavings 20 to expose the upper portion. As a result, it can be used as an interior decoration with a gorgeous appearance. Artificial flowers can be replaced as appropriate, and fresh flowers can be added in some cases. Furthermore, decorations such as small dolls and flags can be used as the ornaments 30 in a family with children.

The interior decoration body of the present invention configured in this way catches bacteria and viruses floating in the air on the copper surface by bringing the air in the room into contact with the copper shavings 20, and inhibits the activity of the bacteria and viruses. It lowers. Moreover, since the shape of the space formed inside the shavings 20 is complicated and intricate, it is possible to reliably capture bacteria and viruses floating in the air on the copper surface, as with the mask. Therefore, the effect of reducing the activity of bacteria and viruses floating in the air is also increased. Moreover, such shavings 20 do not scatter in the air like copper powder or copper fibers, nor are they accidentally inhaled. Copper is a safe metal that is also used in pots and frying pans, so even if an infant accidentally touches or licks it, it will not harm the human body.

In the interior decoration of the present invention, by bringing the copper shavings 20 into contact with the indoor air, bacteria and viruses floating in the air are caught on the copper surface, and the effect of reducing the activity of bacteria and viruses is enhanced. It is desirable to place it in a place where air circulates, such as by a window. Furthermore, an electric fan or a small fan can be arranged nearby to further enhance the air contact effect.

In addition, as shown in FIG. 3, it is also possible to pour a small amount of water. Although the copper shavings 20 are not water absorbent, some of the poured water adheres to the surface of the shavings 20 and the remainder flows down to the bottom of the container 10 . Since copper ions exert an antibacterial effect also on microorganisms in water, the water in contact with the copper shavings 20 is kept clean without the generation of germs or mold. Then, it gradually evaporates and has the effect of humidifying the room. In addition, since it is expected that the surface of the shavings 20 will be more effective in capturing airborne bacteria and viruses when it is wet rather than when it is dry, it is periodically sprinkled with a small amount of water as if watering a flower. It is preferable to pour If the tray 11 is arranged as shown in FIG. 3, even if the over-poured water spills out of the container 10, it can be received.

As described above, the interior decoration of the present invention uses copper shavings 20 that have been disposed of as waste so far, so the manufacturing cost is low, and it is excellent in antibacterial and antiviral properties. effect, antifungal, and deodorizing effect can be obtained. Moreover, since the air purifying device of the present invention utilizes the antibacterial and antiviral effects of copper, the effects are permanent. Further, the air purifier of the present invention has decorations 30 such as artificial flowers arranged on the upper surface thereof, so that it is suitable for use as an interior decoration.
