Description

The present invention relates to a cutting board.

A cutting board is a flat, planar body that is primarily used for cutting and processing food ingredients, and there are currently cutting boards on the market in a variety of sizes and shapes. In addition to the standard rectangular shape, there are also cutting boards with special shapes suited to the type of food ingredient or the environment in which they are used. For example, Patent Document 1 discloses a rectangular cutting board with concave notches in the corners.

Japanese Utility Model Application Laid-Open Publication No. 6-79442

Generally, when cutting or processing ingredients on a cutting board, it is necessary to transfer the processed ingredients to a container such as a bowl or colander. At this time, when shredding ingredients such as green onions or cabbage, for example, the ingredients often spill out of the container after cutting, which is a problem in terms of both work efficiency and hygiene.
Therefore, an object of the present invention is to provide a cutting board that can prevent food from spilling to places other than the container when food is moved from the cutting board to another container.

After extensive research into the above-mentioned problems, the inventor discovered that a cutting board with a cutout recess having a specific shape around the periphery can prevent food from spilling into places other than the container by scraping food along the cutout recess into another container placed below the cutting board, and thus completed the present invention.
That is, the present invention is the following cutting board.

The cutting board of the present invention, which solves the above-mentioned problems, is a cutting board (100) having a notched recess (12), the notched recess (12) having an arc portion (12A) provided along the circumference of an imaginary circle (S) recessed toward the center of the cutting board, the notched recess (12) having two outer contact points (12C) where the imaginary circle (S) intersects with the peripheral edge (11) of the cutting board, and the imaginary periphery connecting the two outer contact points with a straight line. A straight line (L1) that is perpendicular to the edge line (11A) and passes through the center point (M) of the imaginary circle has a lowest point (12B) that intersects with the arc portion (12A), and the straight line (L1) that connects the center point (M) of the imaginary circle (S) to the lowest point (12B) has a distance (L2) from an intersection (P1) between the straight line (L1) and the imaginary perimeter line (11A) to the lowest point (12B) that is 1/5 to 1/2 of the diameter (Φ) of the imaginary circle.
This cutting board has notches around the periphery, so when food is moved from the center of the cutting board toward the notches using a knife or similar tool to scrape it off into a container such as a bowl or colander, the food falls into the container along the shape of the notches, reducing the amount of food spilling off the cutting board and allowing for more efficient work.
Furthermore, this feature causes the scraped ingredients to fall toward the center of the imaginary circle that is part of the bowl, colander, etc., further reducing the amount of ingredients spilling outside the cutting board and allowing for more efficient work.

The cutting board of the present invention for solving the above-mentioned problems is a cutting board (200) having a notched recess (22), the notched recess (22) having a polygonal portion (22A) provided so as to have a vertex (22D) on the circumference of an imaginary circle (S) recessed toward the center of the cutting board, the notched recess (22) having two outer contact points (22C) where the imaginary circle (S) and the peripheral portion (21) of the cutting board intersect, a straight line (L3) perpendicular to an imaginary periphery line (21A) connecting the two outer contact points (22C) and passing through a center point (M) of the imaginary circle (S) has a bottom point (22B) where the straight line (L3) and the polygonal portion (22A) intersect, and a straight line connecting the center point (M) of the imaginary circle (S) to the bottom point (22B) is formed. Of the lines (L3), the distance (L5) from the intersection (P2) of the straight line (L3) and the imaginary periphery line (21A) to the lowest point (22B) is 1/5 to 1/2 of the diameter (Φ) of the imaginary circle, the straight line (L3) that is perpendicular to the imaginary periphery line (21A) connecting the two outer contact points (22C) with a straight line and that passes through the center point (M) of the imaginary circle (S) has an imaginary lowest point (22E) where the straight line (L3) and the imaginary circle (S) intersect, and of the straight line (L3) that connects the center point (M) of the imaginary circle (S) to the imaginary lowest point (22E), the distance (L4) from the intersection (P2) of the straight line (L3) and the imaginary periphery line (21A) to the imaginary lowest point (22E) is 1/5 to 1/2 of the diameter (Φ) of the imaginary circle (S).
This cutting board has notches around the periphery, so when food is moved from the center of the cutting board toward the notches using a knife or similar tool to scrape it off into a container such as a bowl or colander, the food falls into the container along the shape of the notches, reducing the amount of food spilling off the cutting board and allowing for more efficient work.
Furthermore, this feature causes the scraped ingredients to fall toward the center of the imaginary circle that is part of the bowl, colander, etc., further reducing the amount of ingredients spilling outside the cutting board and allowing for more efficient work.
In addition, the working space on the cutting board can be made larger, which improves work efficiency.
Furthermore, due to this feature, since the cutout recess is polygonal, there is more work space on the cutting board other than the cutout recess compared to when the cutout recess is arc-shaped, which has the effect of improving work efficiency.

The cutting board of the present invention for solving the above-mentioned problems is a cutting board having a cutting line (62A), the cutting line (62A) being an arc-shaped line provided along the circumference of an imaginary circle (S) recessed toward the center of the cutting board, the cutting line (62A) having two outer contact points (12C) where the imaginary circle (S) intersects with the peripheral portion (11) of the cutting board, and an imaginary peripheral line (11A) connecting the two outer contact points with a straight line. A straight line (L1) that is perpendicular to the cut line (62A) and passes through the center point (M) of the imaginary circle (S) has a lowest point (12B) that intersects with the cut line (62A), and the straight line (L1) that connects the center point (M) of the imaginary circle (S) to the lowest point (12B) has a distance (L2) from an intersection (P1) of the straight line (L1) with the imaginary periphery line (11A) to the lowest point (12B) that is 1/5 to 1/2 of the diameter (Φ) of the imaginary circle.
This cutting board has the advantage that a cutting board having a notched recess can be easily manufactured.

Hereinafter, embodiments of the cutting board and cutting board manufacturing method according to the present invention will be described in detail with reference to the drawings. Note that the shapes of the cutting boards described in the embodiments are merely examples used to explain the cutting board according to the present invention, and are not intended to be limiting.

(First embodiment)
FIG. 1 shows a plan view of a cutting board 100 according to a first embodiment.
As shown in Figure 1, the cutting board 100 consists of a plate-shaped main body 10, which is composed of a peripheral portion 11, which is the outer edge portion of the main body 10, and a cutout recess 12, which is formed by cutting out a portion of the peripheral portion 11 of the main body 10 in an arc shape.

[Main unit]
The main body 10 is mainly plate-shaped and is intended to be used as a table on which foodstuffs are cut or otherwise processed with a knife or the like.
The size, thickness, shape, material, etc., are not particularly limited, but because the food placed on top is cut with a blade such as a knife, a relatively soft material is preferred to prevent the blade from being damaged by chipping. Specifically, it can be made of wood, resin such as plastic, or rubber, and preferably made of resin such as plastic or rubber that has been antibacterial treated. Making the main body 10 out of antibacterial resin such as plastic or rubber simplifies maintenance such as cleaning after use with food such as raw meat, and is also advantageous from a hygienic standpoint because it makes it difficult for bacteria to adhere to the food. In addition, it is easy to process and can be mass-produced relatively easily, making it highly productive.
Furthermore, if the cutting board 100 is made of paper, it can be used as a disposable cutting board, which is excellent in terms of hygiene.

[Periphery]
1, the peripheral edge 11 is an edge portion of the main body 10. The shape of the peripheral edge 11 varies depending on the shape of the main body 10.
Peripheral edge 11 also has an imaginary peripheral line 11A. Imaginary peripheral line 11A shows a portion of peripheral edge 11 where notched recess 12 is provided in the case where notched recess 12 is not present, in order to explain the position of arc portion 12A (described later) relative to main body 10. Specifically, as shown in Figure 2, cutting board 100 has two outer contact points 12C where an imaginary circle S intersects with peripheral edge 11 of cutting board 100, and the straight line connecting these two outer contact points 12C is imaginary peripheral line 11A.

[Notched recess]
The notched recess 12 is a portion for moving ingredients cut on the cutting board from the center of the main body 10 toward the notched recess 12 and scraping them into a bowl, colander, or the like placed below the notched recess 12.
The shaded areas in Figure 1 indicate cutout recesses 12. Cutout recesses 12 have an arc shape recessed toward the center of cutting board 100, and are provided by cutting out a portion of main body 10 in an arc shape from peripheral edge 11. Although Figure 1 shows one cutout recess 12 on one side of peripheral edge 11 of the rectangular cutting board, cutout recesses 12 may be provided anywhere on peripheral edge 11, or in multiple locations. For example, cutout recesses 12 may be provided on the corners of the rectangular cutting board, or multiple cutout recesses 12 of different sizes may be provided.
Furthermore, since the notched recess 12 is provided so as to open from the peripheral edge 11 to the outside of the main body 10, food can be scraped into a bowl, colander, etc. placed below the notched recess regardless of the size of the food, compared to a hole surrounded by the main body 10.

Next, the shape of the notched recess 12 will be described.
FIG. 2 shows the shape of the notched recess 12 relative to the main body 10.
The imaginary circle S is a perfect circle of any size, and is an imaginary circle used to explain the shape of the notched recess 12 .
Cutout recess 12 has an arc portion 12A provided along the circumference of an imaginary circle recessed inside (toward the center) cutting board 100. Cutout recess 12 is a portion where cutting board 100 (main body 10) has been cut out.
The arc portion 12A is the edge portion of the cutting board 100 where a portion of the circumference of the imaginary circle S is cut away.
The size of the imaginary circle S is determined arbitrarily depending on the size of the main body 10, and may be any size. However, it is preferable that the size of the imaginary circle S be adjusted to fit a cooking utensil or container with a circular opening, such as a pot or bowl. Specifically, the diameter of the imaginary circle S is preferably 5 cm or more and 40 cm or less. The lower limit of the diameter of the imaginary circle S is more preferably 8 cm or more, even more preferably 12 cm or more, and most preferably 15 cm or more. Furthermore, the upper limit of the imaginary circle S is more preferably 36 cm or less, even more preferably 32 cm or less, and most preferably 28 cm or less.
The diameter of this imaginary circle S can be set to a size of the cutout recess 12 that is easy to use relative to the size of the cooking utensil.
Furthermore, the center point M is the center of the imaginary circle S. The center point M is also an imaginary center of a container such as a bowl or colander to which the ingredients on the main body 10 are moved. The diameter Φ indicates the diameter of the imaginary circle S, and the size of the diameter Φ is determined in accordance with the size of the imaginary circle S.

The imaginary lowest point 12E is a point on the circumference of the imaginary circle S that is farthest from the imaginary periphery line 11A on a line connecting the center point M and a point on the circumference of the imaginary circle S. In other words, the imaginary lowest point 12E is a point where, of the lines that are perpendicular to the imaginary periphery line 11A and pass through the center point M, the line intersects with the circumference of the imaginary circle S.
The lowest point 12B is the point on the arc portion 12A that is farthest from the imaginary periphery line 11A on the line connecting the center point M and a point on the arc portion 12A. In other words, the lowest point 12B is the point at which the line that is perpendicular to the imaginary periphery line 11A and passes through the center point M of the imaginary circle S intersects with the arc portion 12A.
In this embodiment, the notched recess 12 is cut out along the circumference of the imaginary circle S, so that the lowest point 12B and the imaginary lowest point 12E coincide with each other.

Intersection point P1 indicates the point where line L1, which connects center point M to lowest point 12B (imaginary lowest point 12E), intersects with imaginary perimeter line 11A. Line L2 indicates the distance between intersection point P1 and lowest point 12B.

FIG. 3 shows the cutting board of this embodiment in use.
Cutting board 100 of this embodiment is characterized in that the length of straight line L2 is 1/5 to 1/2 of diameter Φ. In other words, of straight line L1 connecting center point M of imaginary circle S to lowest point 12B, the distance from intersection P1 of straight line L1 and imaginary periphery line 11A to lowest point 12B is 1/5 to 1/2 of the diameter of imaginary circle S, and notched recess 12 is provided eccentrically on the outside of main body 10.
As a result, as shown in Figure 3, the cut ingredients are moved towards the notched recess 12, and when scraped off, the ingredients fall from the arc portion 12A towards the centre of a container such as a bowl or colander, reducing the chance of ingredients spilling out of the cutting board or container and allowing for more efficient work.
In addition, the cutting board provides a larger working space, which improves work efficiency.
The length of the straight line L2 is preferably 1/5 to 1/2 of the diameter of the imaginary circle S, and the upper limit is more preferably 1/3. In particular, when the length of the straight line L2 is 1/3 to 1/5, the effect of the cut ingredients falling and congregating toward the center point M of the imaginary circle S (the center of the container) becomes greater.

When the length of line L2 is less than 1/5 of the diameter Φ, the food becomes difficult to drop from the cutting board or to fall toward the center of the container. Regarding the case where the length of line L2 exceeds 1/2 of the diameter Φ, as shown in Figure 12, a virtual line passing through the outermost left-right edge of virtual circle S and parallel to line L1 is defined as virtual line 11B. In this case, the presence of recessed protrusion 13 of cutting board 100, which is surrounded by virtual line 11B, virtual circle S, and peripheral edge 11, makes it difficult for food to drop from cutting board 100.
Furthermore, when the diameter Φ exceeds half, even if the cut food is moved parallel to the cut recess 12 (upward in FIG. 12 ) from the work space for cutting food on the main body 10, the food will not fall out of the cut recess 12 in the portion above the imaginary line 11C. Therefore, the absence of the recess 13 is preferable because it allows the work space for cutting food on the main body 10 to be maximized while reducing the overall size of the cutting board 100.
In other words, by making the length of the straight line L2 1/5 to 1/2 of the diameter of the imaginary circle S, the overall size of the cutting board 100 can be reduced while maximizing the working space for cutting ingredients on the main body 10.
The imaginary line C passes through the center of the imaginary circle S and is parallel to the imaginary periphery line 11A.

In particular, when the diameter of the imaginary circle S is between 5 cm and 40 cm, and the length of the straight line L2 is between 1/5 and 1/2 of the diameter Φ, the dropped food material tends to gather at the center point M of the imaginary circle S, making it easier to drop into the container.

(Second embodiment)
FIG. 4 shows a cutting board 200 according to a second embodiment of the present invention.
The cutting board 200 of the second embodiment is characterized in that the shape of the notched recess 22 is polygonal, as compared with the cutting board 100 of the first embodiment.
The main body 20 and the peripheral edge portion 21 other than the notched recess 22 are the same as the main body 10 and the peripheral edge portion 11 in the first embodiment, and therefore a description thereof will be omitted.

[Notched recess]
The shaded area in FIG. 4 indicates the cut-out recess 22 .
The cutout recess 22 in this embodiment is provided in a part of the peripheral portion 21 for the same purpose as the cutout recess 12 in the first embodiment, and is a part of the cutting board 200 (main body 20) cut out so that a part of the peripheral portion 21 is recessed inside the main body 20, and has a polygonal cutout shape so that the vertex 22D is on the imaginary circle S.

Polygonal portion 22A is a portion of the edge of cutting board 200 that is cut into a polygonal shape so that vertices 22D lie on imaginary circle S. As shown in Figure 5, polygonal portion 22A has a polygonal shape with multiple vertices 22D, all of which lie on the circumference of imaginary circle S. In other words, notched recess 22 has polygonal portion 22A that is provided so that vertices 22D lie on the circumference of imaginary circle S that is recessed toward the center of cutting board 200.
As shown in FIG. 5, outer contact points 22C, which are two points where the imaginary circle S intersects with the peripheral edge 21, form part of the plurality of vertices 22D.
Here, the number of vertices 22D of polygonal portion 22A may be three or more, and is not particularly limited, but is preferably four or more. In this case, food is less likely to fall off the cutting board, allowing for more efficient work. More preferably, six or more vertices are used. In this case, food scraped into a container such as a bowl or colander along the notched recesses falls toward the center of the container, further reducing food spillage off the cutting board or container, allowing for more efficient work.

Furthermore, as shown in FIG. 5, the cutting board 200 has two outer contact points 22C where the imaginary circle S intersects with the peripheral edge 21 of the cutting board 200, and the straight line connecting the two outer contact points 22C is the imaginary peripheral line 21A.

5, the imaginary lowest point 22E is a point on the circumference of the imaginary circle S that is farthest from the imaginary periphery line 21A on the straight line L3 that connects the center point M and a point on the circumference of the imaginary circle S. In other words, the imaginary lowest point 22E is a point where the straight line L3 intersects with the imaginary circle S, the straight line L3 being perpendicular to the imaginary periphery line 21A and passing through the center point M of the imaginary circle S.
The lowest point 22B is a point where a straight line L3, which is perpendicular to the imaginary perimeter line 21A and passes through the center point M of the imaginary circle S, intersects with the polygonal portion 22A.
In FIG. 5 of this embodiment, the lowest point 12B and the imaginary lowest point 12E do not coincide, but the lowest point 12B and the imaginary lowest point 12E may coincide in the polygonal portion 22A.
A straight line L4 indicates the distance between the intersection point P2 and the lowest point 22B, and a straight line L5 indicates the distance between the intersection point P2 and the polygonal portion 22A.

6 shows the cutting board of this embodiment in use. The cutting board of this embodiment is characterized in that the length of line L4 is 1/5 to 1/2 of the diameter Φ, and the length of line L5 is 1/5 to 1/2 of the diameter Φ.
In other words, it is the same as the case where, of the straight line connecting the center point M of the imaginary circle S to the lowest point 22B, the distance from the intersection P2 of said line with the imaginary periphery line 21A to the lowest point 22B is 1/5 to 1/2 of the diameter of the imaginary circle S, and the case where, of the straight line connecting the center point M of the imaginary circle S to the imaginary lowest point 22E, the distance from the intersection P2 of said line with the imaginary periphery line 21A to the imaginary lowest point is 1/5 to 1/2 of the diameter of the imaginary circle S.
This feature allows the notched recess 12 to be provided eccentrically on the outside of the main body 10. As a result, as shown in Figure 6, the scraped food falls toward the center of a container such as a bowl or colander, reducing the amount of food spilling outside the cutting board and allowing for more efficient work. In addition, the increased working space allows for more efficient work.
Furthermore, by providing the notched recess 22 with a polygonal portion 22A, there is more work space on the cutting board other than the notched recess compared to when the notched recess is arc-shaped, which has the effect of improving work efficiency.

(Third embodiment)
FIG. 7 shows a cutting board 300 according to a third embodiment.
The cutting board 300 of this embodiment is characterized by having an outer edge portion 34A in addition to the features of the cutting board 100 of the first embodiment and the cutting board 200 of the second embodiment.
Note that main body 30 is the same as main bodies 10 and 20, peripheral edge 31 is the same as peripheral edges 11 and 21, notched recess 32 is the same as notched recess 12 and 22, lowest point 32B is the same as lowest points 12B and 22B, and virtual lowest point 32E is the same as virtual lowest points 12E and 22E, so their explanations will be omitted. Note that arc portion 32A is the same as arc portion 12A, and may be replaced with polygonal portion 22A.

[Outer edge]
Here, a line parallel to the imaginary perimeter line 31A and passing through the lowest point 32B is defined as an imaginary line 34C, and a line perpendicular to the imaginary line 34C and passing through the outer contact point 32C is defined as an imaginary line 34B.
The outer edge portion 34A is an area surrounded by the peripheral edge portion 31, the imaginary lines 34B, and the imaginary lines 34C.

As shown in Figure 7, the outer edge portions 34A are provided on both sides of the notched recess 32 in the direction in which the imaginary perimeter line 31A extends, and are part of the main body 30.

The outer edge width 35 is the width of the outer edge 34A in the direction in which the imaginary periphery line 31A extends. The notched recess width 36 is the width of the notched recess 32 in the direction in which the imaginary periphery line 31A extends.
Although the length of the outer edge width 35 and the length of the notch recess width 36 are not particularly limited, it is preferable that the length of the outer edge width 35 is 1/3 to 1/7 of the length of the horizontal width 37 (in the left-right direction when in the state of the cutting board 300 shown in Figure 3) between the two points where the imaginary line 34C intersects with the peripheral edge 31, and that the length of the notch recess width 36 is 1/3 to 5/7 of the length of the horizontal width 37.
More preferably, the length of the outer edge width 35 is 1/5 of the length of the horizontal width 37 , and the length of the notched recess width 36 is 3/5 of the length of the horizontal width 37 .
By setting the width to these lengths, when the cut ingredients are scraped down from the notched recess 32 into the container, they fall off the peripheral edge 31 and are prevented from falling out of the container.
The sum of the outer edge width 35 and the notched recess width 36 is set to be equal to the lateral width 37 .

Furthermore, the shape of the outer edge 34A may be any shape to match the shape of the peripheral edge 31, and is not particularly limited. Preferably, the corners of the outer edge 34A of the cutting board 300 are right-angled, as shown in Figure 7. In this case, the outer edge 34A can be fixed in place by hooking it onto the edge of a kitchen sink, for example. This makes it possible to place the cutting board even in small kitchens where there is no flat space to place it.

(Fourth embodiment)
A cutting board 400 in the fourth embodiment is characterized in that the main body 40 is oval, as shown in FIG.
FIG. 9 is an enlarged view of the periphery of the notched recess 42 of the cutting board in the fourth embodiment shown in FIG.
9, the main body 40 is the same as the main bodies 10, 20, and 30, the peripheral portion 41 is the same as the peripheral portions 11, 21, and 31, the imaginary peripheral line 41A is the same as the imaginary peripheral lines 11A, 21A, and 31A, the notched recesses 42 are the same as the notched recesses 12, 22, and 32, the arc portion 42A is the same as the arc portions 12A and 32A, the lowest point 42B is the same as the lowest points 12B, 22B, and 32B, and the imaginary lowest point 42E is the same as the imaginary lowest points 12E, 22E, and 32E, and therefore description thereof will be omitted. Note that it is also possible to use a polygonal portion 22A instead of the arc portion 42A.
8 and 9, a circular arc-shaped recess is used for the purpose of explanation, but the shape of the recess is not limited to this and may be any shape. For example, the recess may be polygonal, similar to the recess 22 in the second embodiment. In this case, a larger working space can be secured compared to when the recess is circular arc-shaped, thereby improving working efficiency.

(Fifth embodiment)
The cutting board 500 of the fifth embodiment is characterized by a plurality of cutout recesses as shown in FIG.

It is also possible to provide a plurality of notched recesses of different sizes and shapes, which is advantageous in that the different sizes and shapes of the notched recesses can be used according to the size and shape of the container, such as a bowl or colander, used to move the ingredients, or the size and shape of the ingredients themselves.

(Sixth embodiment)
FIG. 11 shows a cutting board 600 according to a sixth embodiment of the present invention.
The cutting board 600 in the sixth embodiment is also an example of a method for manufacturing the cutting boards in the first to fifth embodiments. Note that the manufacturing method of the cutting board in this embodiment is merely an example of an embodiment and is not limited to this.
A feature of this embodiment is that the main body 60 is provided with a cut line 62A along which the notch recess 62 can be formed by cutting along the line.
The cutout recess 62 formed by the cutout line 62A has the same shape as the cutout recesses 12, 22, 32, 42, and 52 in the first to fifth embodiments.
Furthermore, the main body 60 and the peripheral edge portion 61 are similar to the main bodies 10, 20, 30, 40, 50 and peripheral edge portions 11, 21, 31, 41, 51 in the first to fifth embodiments, and therefore description thereof will be omitted.

[Cutting line]
The cut line 62A in this embodiment is intended to allow a person to cut out the main body 60 along the line to form a cutout recess.
Cutting line 62A may be indicated in any manner as long as it is indicated on main body 60. Cutting line 62A may be drawn so that it can be cut with a cutting tool such as scissors or a blade, or may be provided with a notch so that it can be torn by hand. This cutting board 600 has the advantage that cutting boards with cutout recesses 62 can be easily manufactured.

Before cutting along cut line 62A, the food is cut on cutting board 600, and then a portion of cutting board 600 is cut along cut line 62A. If the food is then cut off from notched recess 62 created by the cutting, cutting board 600 has a large space when cutting the food, making the task of cutting the food easier.
Furthermore, the cut lines 62A may be provided in multiple locations and in multiple shapes to form multiple types of cutout recesses in the main body 60. In this case, in the case of a cutting board 600 provided with multiple cut lines 62A, the user can cut out only the necessary parts along the cut lines 62A, thereby allowing a cutting board to be manufactured to suit the user's needs, which is preferable.

The above-described embodiment shows one example of a cutting board and a method for manufacturing a cutting board. The cutting board and cutting board manufacturing method according to the present invention are not limited to the above-described embodiment, and the structure of the cutting board according to the above-described embodiment may be modified within the scope that does not change the gist of the present invention.

For example, the cutting board body may be made from flexible rubber resin, paper, etc., which allows the cutting board to be folded, making it easier to carry and store.

(Seventh embodiment)
FIG. 13 shows a cutting board 700 according to a seventh embodiment of the present invention.
The cutting board 700 in the seventh embodiment is characterized in that a plate-like member is detachable from the main body of the cutting board so as to cover the notched recess of the cutting board in the first or second embodiment.
In this embodiment, the first embodiment will be described, and the same parts as those in the first embodiment will be denoted by the same reference numerals and will not be described again.

[Plate-shaped member]
Plate-shaped member 73 has a portion provided in the same shape as notched recess 12. Plate-shaped member 73 has connecting portion 74, and is detachable by connecting to connecting portion 75 provided in the arc portion 12A of cutting board 700, and becomes one cutting board 700 when connected.
Connecting portion 74 and connected portion 75 are arranged so that, after connection, the connecting portion does not protrude in the thickness direction of the board and the surface is flat. Since plate-shaped member 73 having the same shape as notched recess 12 can be attached and detached from each other, notched recess 12 can be provided when transferring cut ingredients from cutting board 700 to a container, and plate-shaped member 73 can be attached when cutting ingredients to increase the working space of the cutting board, which is very convenient.

The connecting portion 74 and the connected portion 75 may be configured, for example, as shown in Figures 13 and 14, such that the connecting portion 74 has a protrusion 74A protruding in the thickness direction of the plate-shaped member 73, and a recess 75A recessed in the thickness direction of the plate in the arc portion 12A, which engage with each other to connect; or, as shown in Figures 15 and 16, such that the connecting portion 74 has a protrusion 74B protruding in the planar direction of the plate-shaped member 73, and a groove 75B (a structure called a dovetail groove) recessed into the interior of the planar direction of the cutting board 700 and open continuously to the peripheral edge 11 in the arc portion 12A, which engages with each other to connect.
When the protrusion 74B and the groove 75B are connected, the length of the straight line L2 is applicable when it is 1/5 to 1/2 of the diameter Φ.

In this embodiment, a structure in which a connecting portion 74 is provided on the plate-shaped member 73 and a connected portion 75 is provided on the arc portion 12A of the cutting board 700 is exemplified. However, a structure in which a connected portion 75 is provided on the plate-shaped member 73 and a connecting portion 74 is provided on the arc portion 12A of the cutting board 700 may also be used.

As shown in Figure 17, the cutting board of the present invention has the same thickness across its entire surface, which constitutes the design. The front surface (top view) and back surface (bottom view) are symmetrical, and the right side view and left side view are symmetrical. The area enclosed by the dashed frame 80 constitutes a partial design. The cutting board of the present invention may also be applied to a folding cutting board.

The cutting board of the present invention can be used for cutting boards and for manufacturing cutting boards.
