Description

Multifunctional Antibacterial kitchen board using both faces having lateral inclined structure}

The present invention relates to an antimicrobial double-sided chopping board having a side slope structure.

Chopping boards serve as a base for processing food such as meat, fish, vegetables, etc. with a knife or a cooking bat. Traditional cutting boards are made of wood and have a flat machined part of constant thickness and rectangular shape. One side of the cutting board is used for the processing of the material, and it is common that two legs supporting the cutting board are attached to both edges of the other surface.

Therefore, meat, fish, vegetables, and the like, which differ in their properties as described above, are processed together in one cutting board. Hygiene problems were pointed out in this way. In other words, meat, fish, etc. are less contaminated with bacteria such as bacteria by boiling and roasting them, but especially vegetables, which are eaten raw without being cooked, such as salads, come from processed meat. It could be contaminated with bacteria. Of course, although the chopping board is cleaned after use, such cleaning may not be sufficient. This is especially true when busy, such as when you need to prepare a large amount of food.

In view of this problem, a cutting board that can use both sides has been developed, but when the one side is used, the other side is contaminated by touching the bottom surface on which the cutting board is placed, which causes another hygiene problem and the other side again. It was a real hesitation to use.

In addition, there is no distinction between the surface for processing meat mainly and the surface for processing vegetables, which leads to indistinguishability from traditional cutting boards using only a single conventional surface. Moreover, such a double-sided cutting board could not be stably supported on the bottom surface, and it was troublesome to frequently move the position of the cutting board to the desired place in use. Furthermore, there is room for improvement in the problem that the impact is transmitted to the user as it is in direct contact with the floor surface when a constant force is applied as in the case of a knife in the cutting board.

On the other hand, cutting boards, vegetables, fish meat, ocean and other kinds of food, cutting, pounding and chopping, so that they are always exposed to moisture and green juice or blood and juice, and to cook animal meat or fast-corrupted fish, etc. When working, pollution is inevitable. The sanitary authorities sterilize the cutting board with boiling water and then sterilize it for a long time in the sun.The cleanliness and hygiene of the cutting board is not kept well due to the busy schedule of the cooking room. Is very high.

When an organic antimicrobial agent is added to prepare a cutting board, there is a concern that secondary contamination or body side effects by the organic antimicrobial agent is concerned, and therefore, some antimicrobial cutting boards using environmentally friendly silver antimicrobial agents have been proposed. However, silver-based antimicrobial agents such as silver nanoparticles have poor compatibility with plastics, which makes it difficult to homogeneously disperse and thereby more difficult to produce a cutting board having satisfactory antimicrobial activity.

For this reason, there has been a continuous demand for developing a double-sided cutting board having various convenience functions and eco-friendly silver-based antimicrobial agents having high antibacterial activity even at low concentrations.

An object of the present invention is to provide an antimicrobial double-sided chopping board having rubber holders on both cutting surfaces and having an inclined structure on its side.

Specifically, an object of the present invention is to provide an antimicrobial double-sided chopping board having a side slope structure, which is manufactured by injecting an antimicrobial polymer composite material containing 50 to 200 ppm of silver-based antimicrobial agent, and rubber holders are provided on both cutting surfaces. .

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a schematic view showing a schematic view of a double-sided cutting board according to the present invention, 1 is a cutting board, 2 and 3 are cutting boards, 4 and 5 are inclined sides, 6 is a rubber holder.

Figure 2 is a schematic diagram showing various modifications of the lateral inclination structure, (a) is the case where both side inclination angles are θ, (b) is when both side inclination angles are different, (c) is a part of the inclined surface Has a different form.

Figure 3 is a schematic cross-sectional view of a double-sided cutting board according to the present invention, showing an example of the rubber holder 6 and the installation hole, 7 shows a broth flow preventing groove provided on the cutting surface.

4 is a view for explaining the utility of the side inclination angle when using the double-sided cutting board according to the present invention.

In the present invention, the side inclined structure, as can be seen in the accompanying Figure 1, means that one side and the opposite side of the cutting board is inclined at an oblique angle, not perpendicular to the cutting surface. In the lateral inclination structure, when the lateral inclination angle θ is an angle formed between the cutting surface and the side surface (shown in FIG. 2), the general cutting board has a side inclination angle of about 90 degrees, but in the present invention, the side inclination angle θ is 30 degrees. -80 degrees, Preferably it is 45-80 degree, Especially it is 60-80 degree.

As shown in Figure 1, the side slope structure is installed on the side of the user side, the user is located on the inclined side (4) when using the chopping surface (2). When using the cutting surface 3 (not shown in FIG. 1, opposite to the cutting surface 2), the user is positioned on the inclined side 5.

As shown in FIG. 2, the side slope angles may be the same or different on both sides. Figure 2 (a) is the same on both sides of the inclination angle, Figure 2 (b) is a case in which both side inclination angles are different. According to one variant of the invention, part of the inclined side may have another side. The inclined side may have a rounded or polygonal shape to the extent that it does not impair the advantages of the present invention, and a part of the inclined side may be made at an angle different from that of the inclined side. For example, FIG. 2C shows a case where a part of the inclined side surface is treated as a vertical surface. In consideration of various aspects such as the use conditions of both cutting surfaces, cutting cleaning conditions, storage, and the like, the angle and structure of the inclined side may be modified in various ways, and both may be configured identically or differently.

Such a side slope structure is very useful when transferring the processed material to the cooking utensils, for example, there is an advantage that the ingredients do not adhere to the side of the cutting board when the cooking utensils in contact with the side or the bottom of the cutting board. 4 is a diagram illustrating the advantages of using such a side slope structure. Although there is some application of side slopes in traditional thick wooden cutting boards, it is understood that no side slopes have been applied or proposed in double sided cutting boards.

In the present invention, rubber holders attached to both cutting surfaces are installed at both ends or four corners of the cutting surface as shown in FIG. 1 to prevent the sliding of the cutting board during use. The cutting board rubber holder may form a lower support of the cutting board as necessary to prevent contact between the lower cutting surface and the floor, thereby preventing contamination of the cutting surface. As shown in the schematic cross-sectional view of the double-sided cutting board according to the present invention of Figure 3, the rubber holder of the cutting surface may be respectively installed on both sides of the cutting board or may be integrated through the through hole.

It is conventionally known to add an antimicrobial agent to a cutting board and to provide antimicrobial property to a cutting board. The use of organic antimicrobial agents as antimicrobial agents is not only long lasting antimicrobial effect given to the cutting board but also can cause weakening (reading of drugs) in human body. Particles or colloids are used. Unlike organic antimicrobials, silver-based antimicrobials are environmentally friendly and have few side effects to the human body, so adding a significant amount of silver-based antimicrobials to cutting boards has little effect on the human body.

However, it is desirable to achieve complete antimicrobial activity using as few silver nanoparticles or colloids as possible, depending on the psychological factors of the user, the economics of the manufacturer, and the aesthetics of the product.

However, silver-based inorganic antimicrobials such as silver nanoparticles or colloids are difficult to disperse without aggregation because of poor compatibility with the polymer. Therefore, in order to obtain a satisfactory antimicrobial effect, it is common to add a silver antimicrobial agent in a considerable amount of several hundred ppm or more.
