有している。Cutting boards made of hard synthetic resin such as polyethylene have been widely used today. This is because, compared with the conventional wooden veneer structure, the drying property is good, and juice or the like is less likely to enter the inside of the cutting board, which is advantageous in hygiene. However, in the case of conventional hard synthetic resin cutting boards, the kitchen knife is slippery on the surface of the cutting board, and the repulsive force is strong and has impact, such that it is not compatible with knives such as kitchen knives and it is difficult to cook. There is also The cutting board itself and the food material to be cooked on the surface of the cutting board are slippery, and the entire cutting board is heavy.

題があった。On the other hand, in order to pursue the blade contacting property of the cutting board surface, a cutting board material made of synthetic rubber is also used, but it is hard to slip and the blade contact is good, but the surface is not durable, so that it is short-term. There are many scratches and dents on the surface between them, and there are the same problems as with wooden cutting boards that bacteria propagate on such scratches.In addition, the material is too soft and not rigid, and the thickness is increased to increase durability. There was a problem that it was difficult to handle because it was very heavy as a result.

る。1 to 2 show a cutting board of an embodiment according to the basic constitution of the present invention. FIG. 1 is a perspective view showing a completed cutting board 1, and FIG. 2 is a partial side of the cutting board of FIG. FIG. The cutting board is a layer of a soft cutting board material whose surface material 2 is a thermoplastic elastomer resin of syndiotactic 1,2-polybutadiene mixed with a polyethylene resin to improve water repellency, and which is mixed with an antibacterial zeolite. D hardness of about 48 degrees is used. The polyethylene resin to be mixed can be mixed in an arbitrary amount within the range of 0.5 to 50% by weight in order to adjust hardness and improve water repellency. 3 is a layer having higher hardness, and in this example, a polyethylene resin having a Shore D hardness of about 57 degrees is used. Cutting board 1 made of these resins
Since the surface material 1 is flexible and has little resilience against cuts of a knife, it has a good blade contact with a knife and the like, and the object to be cooked is not slippery, and is extremely easy to cook.
In addition, it has resilience to the damage of the blade due to cooking, and even if it is scratched, the part will adhere due to the resilience, so unevenness and grooves will not easily form, and the flatness of the cutting board surface is maintained well. Be done. The antibacterial zeolite is added to prevent the growth of bacteria within the wound. Further, the third layer gives rigidity to the entire cutting board, allows the blade to endure even if the cutting board is deeply scratched, and absorbs impact, so that it cannot be used, for example, in a conventional rubber cutting board. Allows cooking with a knife. Layer 3
Further, if an antibacterial agent is added, the antibacterial activity can be further improved. In this example, the three layers can be used as the surface and used as a cutting board made of polyethylene resin as in the conventional case.

久性のあるまな板を得る。3 to 4 are views of a cutting board showing another embodiment of the present invention, FIG. 3 is a perspective view of the completed cutting board 4, and FIG. 4 is a partial side sectional view of the cutting board 4. In the figure, 5 is a soft layer which is a mixture of the same thermoplastic elastomer resin of syndiotactic 1,2-polybutadiene and polyethylene as described above, 6 is a low density polyethylene layer having a hardness higher than that of the soft layer, and 7 is a layer. High-density polyethylene layers having a hardness higher than 6 are sequentially laminated. The hardness of the soft layer in this example is about 48 degrees in Shore D hardness, the hardness of the layer 6 of low density polyethylene is about 52 degrees in Shore D hardness,
The hardness of the high-density polyethylene layer 7 is Shore D hardness 60.

In the drawing, 9 is a soft layer which is a mixture of the same thermoplastic elastomer resin of syndiotactic 1,2-polybutadiene and polyethylene as described above, and 10 is a low density polyethylene layer having a higher hardness than the soft layer, This is an example in which the soft layers 9 and 9 are arranged on both sides of the layer 10 having higher hardness. This example has the advantage that both sides of the cutting board can be used as soft layers. In the cutting board 8 of this example, the surface materials 9 and 9 are soft, but the rigidity of the layer 10 gives rigidity to the entire cutting board, so that the flatness of the cutting board is maintained, for example, a bridge shape is formed at the end of the sink. It does not bend or deform even if it is used for, and has a good blade contact property with respect to the blade as described above, and the cutting board itself has a structure that is not slippery. Other advantages are similar to those described above.
