Abstract

PROBLEM TO BE SOLVED: To provide a manufacturing method of a wooden waterproof chopping board having the long service life and being excellent in antibacterial performance. SOLUTION: A wooden chopping board material 1A is pressurized/compressed by a pressurizing device such as a press device after being soaked in a paraffin bath 11. Paraffin P soaked in the board material 1A permeates in grain of the board material 1A, that is, fine clearance of wooden fiber. Afterwards, the volume is reduced by pressurizing/compressing the chopping board material 1A, and the paraffin P is densely filled thereby so as to be brought into close contact with the clearance. Thus, waterproofness of a chopping board is improved, and the persistence is improved so that a hardness-improved wooden waterproof chopping board can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden waterproof cutting board and a method for manufacturing the same, and more particularly to a wooden waterproof cutting board having a long life and excellent antibacterial properties.

[0002]

Conventionally, a chopping board made of a wooden chopping board has been used. However, since wood has a hygroscopic property, water and juice of various cooking materials easily permeate, and germs and the like may propagate in the permeated water. Therefore, frequent sterilization must be performed. Further, if the cutting board contains moisture, the board material is softened, so that if the cutting blade or the like is strongly pressed, the cutting blade is easily damaged. In particular, dirt and the like easily enter into these scratches, and if used to a certain extent, innumerable scratches are left, so that the service life of the cutting board is shortened.

Therefore, various proposals have been made to apply various treatments to a wooden cutting board to impart waterproofness and antibacterial properties. For example, Japanese Unexamined Utility Model Publication No. 60-63135 discloses a cutting board in which a wooden board material is impregnated with a resin to prevent the penetration of moisture.

Japanese Patent Application Laid-Open No. H10-211110 discloses that a wooden cutting board is subjected to antibacterial treatment up to a deep portion including a conduit by injecting and impregnating an antibacterial agent solution under a reduced pressure environment.
A method for manufacturing a cutting board that is polished and finished after drying is disclosed, and this publication describes that a solution such as zeolite and ethanol is used as an antibacterial solution.

However, in the chopping board described in Japanese Utility Model Laid-Open No. 63-135135, resin is impregnated into the wood eyes (fine gaps of wood fibers) of the chopping board, but the gap is not densely filled. Therefore, sufficient hardness could not be obtained, and waterproofness was not always sufficient.

A cutting board manufactured by the method described in Japanese Patent Application Laid-Open No. 10-211110 has an antibacterial property, but exhibits an antibacterial property by impregnating an antibacterial solution into a cutting board material and exuding little by little. Therefore, it does not have waterproofness, and cannot solve the problem that the cutting board is softened and easily damaged by the absorption of moisture.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to provide a wooden waterproof cutting board having a long life and excellent antibacterial properties, and a method for manufacturing the same.

[0008]

According to a first aspect of the present invention, there is provided a wooden waterproof cutting board in which the volume of a wooden cutting board impregnated with a hydrophobic liquid is reduced by 5 to 20%. For this reason, since the surface of the cutting board material exhibits waterproofness by the hydrophobic liquid agent, moisture does not penetrate into the cutting board, and excellent antibacterial properties can be exhibited. Especially the volume of the cutting board is 5
When the volume is reduced by ２０20%, the hydrophobic liquid agent that has permeated into the eyes of the cutting board, that is, the fine gaps of the wood fibers, is densely filled in the gaps, so that the waterproofness is improved and the durability is improved. . In addition, since the hardness of the cutting board can be improved, it is less likely to be damaged by the knife of the knife.

According to a second aspect of the present invention, there is provided a method for manufacturing a wooden waterproof cutting board, wherein a wooden cutting board is immersed in a hydrophobic liquid bath and then compressed under pressure. For this reason, the hydrophobic liquid material penetrates into the eyes of the cutting board, that is, the fine gaps in the wood fiber, but then the pressure is applied to the cutting board to reduce the volume thereof, thereby causing the hydrophobic liquid to enter the gap. Since it is densely filled, it is possible to obtain a wooden waterproof cutting board with improved waterproofness and durability, and improved hardness.

Further, in the method for manufacturing a wooden waterproof cutting board according to the third aspect, in the second aspect, the hydrophobic liquid agent is paraffin, the bath temperature is 70 to 80 ° C., and the wooden material after immersion is used. The cutting board is cooled to room temperature while being pressed and compressed. Paraffin is a solid at normal temperature, exhibits a viscosity sufficient to penetrate a cutting board even at a melting temperature of 100 ° C. or lower, and has good handleability. And
After being immersed in such paraffin, the paraffin is pressed and compressed while it is still hot, and is kept in this pressurized state until it is solidified. Since it is solidified as it is filled in, a cutting board having high hardness, sufficiently filled with paraffin and excellent in waterproofness can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a wooden waterproof cutting board according to an embodiment of the present invention will be described with reference to FIG. Cutting board 1
Is made of a wooden cutting board 1A, which is entirely impregnated with paraffin P, which is a hydrophobic liquid agent, and whose volume is reduced by 5 to 20% with respect to the untreated cutting board 1A. The paraffin P is a solid that is white or translucent at room temperature and is separated and refined from petroleum such as heavy oil having a high melting point, and is usually a mixture with hydrocarbons, and is commercially available. Paraffin wax or the like can be used.

Since the cutting board 1 of this embodiment is made by impregnating the cutting board material 1A with paraffin P, the water is prevented from penetrating into the inside of the cutting board 1 to repel water, and the surface is cleaned. It can be kept clean just by doing, and has excellent antibacterial properties. In addition, the cutting board material 5
Since the volume is reduced by 20%, the paraffin P infiltrated into the gaps between the fibers of the cutting board 1A joins the fibers firmly by volume reduction so as to close the gaps. As the density increases, the hardness also increases,
The surface of the cutting board 1 is hardly damaged by a knife of a knife or the like, and has excellent durability. In addition, the effect of improving the waterproofness of the cutting board 1 is also exhibited by this volume reduction.

Next, a method of manufacturing the cutting board 1 as described above will be described with reference to FIGS. First, FIG.
The wooden cutting board 1A is immersed in the paraffin bath 11 as shown in FIG. The temperature of the paraffin P in the paraffin bath 11 is not particularly limited as long as the temperature of the paraffin P to be used is in a liquid state. If the temperature is too high, the handleability is reduced.
It is preferred that The immersion time of the cutting board 1A is not particularly limited as long as the paraffin P sufficiently penetrates, but may be about 1 to 2 hours at 70 to 80 ° C.

After the immersion in the paraffin bath 11, the cutting board 1A is taken out and, while still hot, pressurized by a pressing device such as a pressing device 12 as shown in FIG. This pressing is performed in the vertical direction (thickness direction) of the cutting board 1A. The pressurizing pressure at this time is such that the volume of the cutting board material 1A is 5-2.
The pressure may be reduced by 0%, especially about 10%. If the rate of decrease in volume is less than 5%, the effect of improving the waterproofness by compressing the cutting board 1A and the improvement in the hardness of the cutting board 1 obtained cannot be sufficiently obtained. In addition, not only the effect of improving the hardness is not obtained, but also the cutting board 1A itself may be damaged, and the size of the pressing device becomes large. And the cutting board 1
By allowing the paraffin P to cool while solidifying it while reducing the volume of A, the wood eyes (gap between fibers) of the cutting board 1A are crushed to improve the hardness, and the paraffin P
By tightly filling the gaps between the fibers of the cutting board 1A without any gap, an effect of improving waterproofness can be obtained.

As described in detail above, the wooden waterproof cutting board of this embodiment is made of a wooden cutting board 1A impregnated with paraffin P.
Is reduced by 5 to 20%, and the surface of the cutting board 1A exhibits waterproofness with paraffin P, so that moisture does not penetrate into the cutting board 1, so that excellent antibacterial properties can be exhibited. In particular, the volume of the cutting board 1A is set to 5 to 2
If the volume is reduced by 0%, the eyes of the cutting board, that is, the paraffins P that have penetrated into the fine gaps of the wood fibers will be tightly packed in the gaps, so that the waterproofness is improved and the durability is improved. . In addition, since the hardness of the cutting board 1A can be improved, the cutting board 1A is less likely to be damaged by a knife or the like, and has an effect of being excellent in durability.

In the method of manufacturing the wooden waterproof cutting board 1 according to the present embodiment, the wooden cutting board 1A is placed in a paraffin bath 11A.
After being immersed in the pressurizing device, the pressurizing device such as the press device 12 pressurizes and compresses. For this reason, the paraffin P immersed in the cutting board 1A penetrates into the eyes of the cutting board 1A, that is, the fine gaps of the wood fibers, and thereafter, the volume is reduced by compressing the cutting board 1A under pressure. Since the paraffin P is densely packed so as to be in close contact with the gap, the waterproofness and its durability are improved,
In addition, a wooden waterproof cutting board having improved hardness can be obtained. In particular, in this embodiment, the temperature of the paraffin bath 11 is set to 70 to 80 ° C., and the wooden cutting board 1 after immersion is used.
Since A is cooled to room temperature while being pressurized and compressed, the paraffin P is pressure-compressed while hot and is kept in this pressurized state until the paraffin P is solidified. Since the paraffin P that has penetrated into the gap is solidified while being densely filled in the gap, the cutting board 1 having high hardness, sufficiently filled with the paraffin P, and excellent in waterproofness can be obtained.

Although the present invention has been described with reference to the accompanying drawings, the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above-described embodiment, paraffin P is used as the hydrophobic liquid, but the present invention is not limited to paraffin, and other hydrophobic liquids such as various resins, paints, and solvents can be used. However, in the case of resin, in order to obtain a melt viscosity that can be immersed in the cutting board 1A, the heating temperature is high, so that not only the efficiency of the immersion operation is reduced, but also the subsequent pressing and compression step becomes difficult. Therefore, in this example, paraffin P which is solid at normal temperature and melts in a relatively low temperature range (about 100 ° C. or less) was used. The shape and size of the cutting board 1 can be applied to various sizes and various designs. In this case, a plate material of a desired shape may be easily pressed and compressed after being immersed in a hydrophobic liquid, or a rectangular plate may be pressed and compressed after being immersed in a hydrophobic liquid, and then It may be processed into a desired shape.

[0018]

According to the first aspect of the present invention, the wooden waterproof cutting board according to the first aspect of the present invention has a wooden cutting board impregnated with a hydrophobic liquid material having a volume of 5 mm.
Since the volume is reduced by ２０20%, the surface of the cutting board material exhibits waterproofness by the hydrophobic liquid agent, so that moisture does not penetrate into the cutting board and excellent antibacterial properties can be exhibited.
Also, if the volume of the cutting board is reduced by 5 to 20%, the hydrophobic liquid agent that has penetrated into the eyes of the cutting board, that is, the fine gaps of the wood fibers, is densely filled in the gaps, and thus the waterproof property is reduced. An improvement and its sustainability are obtained. In addition, since the hardness of the cutting board can be improved, it is less likely to be damaged by the knife of the knife.

In the method for manufacturing a wooden waterproof cutting board according to the second aspect of the present invention, the wooden cutting board is immersed in a hydrophobic liquid bath and then compressed under pressure. Because it will be densely filled in the gap of
It is possible to obtain a wooden waterproof cutting board with improved waterproofness and durability, and improved hardness.

Further, in the method for producing a wooden waterproof cutting board according to the third aspect, in the second aspect, the hydrophobic liquid agent is paraffin, the bath temperature is 70 to 80 ° C., and the wooden material after immersion is used. Since the cutting board is cooled to room temperature while compressing it under pressure, the paraffin permeated into the fine gaps of the wood fibers solidifies while being densely filled in the gaps. A cutting board that is sufficiently filled and has excellent waterproofness can be obtained.
