Description

  The present invention relates to a cutting board to which a molding material is applied.

  A cutting board made of resin or the like has a hardness sufficient to withstand the knife blade in consideration of cooking workability. For this reason, the edge of a cutting board may hit a tableware or a wall surface and give a strong impact. In addition, the floor may be wrinkled by the falling of the cutting board.

As the above measures, the present inventors have focused on providing a molding material made of an elastic material such as a resin on the outer periphery of the cutting board. Normally, the molding material is provided on the outer periphery of the base plate in the table or desk to mitigate the impact, but there is no known one that applies the molding material to the outer periphery of the cutting board.
Note that Patent Documents 1 and 2 below are known as prior arts related to the present invention.

JP 2007-50217 A Utility Model Registration No. 30428244

However, when the molding material is provided on the outer periphery of the cutting board, the following problems may occur.
1stly, if the width | variety of a molding material is wider than the thickness of a cutting board main body, the edge part of a molding material will protrude in the cooking surface of a cutting board. In such a case, the end of the molding material may hinder the use of the kitchen knife.

  Secondly, when a molding material is attached to the cutting board body, dirt such as food juice or residue accumulates in the gap between the cutting board body and the molding material. If the molding material is detachably attached to the cutting board main body, the dirt in the gap can be easily removed. However, there is a possibility that the cooking operation may be hindered due to misalignment or dropping of the molding material.

The purpose of the present invention is to provide a molding material on the outer periphery of the cutting board body to alleviate the impact caused by the edge, and the molding material does not interfere with the use of the kitchen knife, and the molding material is detachable and stable on the cutting board body. It is to provide a cutting board that is designed to be installed.
Another object of the present invention is to provide an easy-to-use cutting board that can obtain an excellent anti-slip effect with a molding material during use and storage.

[First invention]
The cutting board of the present invention for solving the above problems is
Cutting board body,
With a molding material made of an elastic material provided on the outer periphery of the cutting board body,
On the adjacent surfaces of the cutting board body and the molding material facing each other, the cutting board body and the molding material are attached and detached while keeping the widthwise ends of the molding material in the same plane as the cooking surface of the cutting board body. It was set as the structure which provides the protrusion and groove | channel which couple | bond together.

  According to such a configuration, since the molding material made of an elastic material is provided on the outer periphery of the cutting board main body, the impact due to the edge is reduced. And since the edge part of the width direction of a molding material is located in the same plane vicinity as the cooking surface of a cutting board main body, it can avoid that the molding material obstructs use of a kitchen knife.

  Moreover, the cutting board of this invention can attach a molding material to a cutting board main body detachably by couple | bonding a protruding item | line and a ditch | groove with an elastic force in the adjacent surface of a cutting board main body and a molding material. Since the ridges and the grooves fit closely together, there is no worry that the molding material will be displaced or detached from the cutting board body.

Further, according to the configuration of the present invention, when the cutting board is leaned against the molding material when draining, the molding material plays a role of preventing slipping and the standing posture of the cutting board is stabilized. Thereby, it is also possible to effectively prevent the cutting board from overturning.
By coordinating the cutting board body and the molding material with different colors, it is possible to finish the cutting board with a new and highly designed appearance.

  Patent Documents 1 and 2 disclose a cutting board provided with an anti-slip material made of an elastic material on the outer periphery of the cutting board. This type of cutting board has a structure in which the groove of the anti-slip material is fitted into the outer peripheral end of the main body of the cutting board, and the impact of the edge of the cutting board can be mitigated by the elastic force of this anti-slip material.

However, in the structure of the anti-slip material as described above, the width of the groove of the anti-slip material is substantially equal to the thickness of the cutting board body, and the end of the anti-slip material protrudes greatly from the cooking surface on the front and back. For this reason, the anti-slip material protruding from the cooking surface of the cutting board hinders the use of the kitchen knife.
In addition, when the cutting board is placed on the cooking table, it is conceivable that the cooking surface of the cutting board floats on the table surface due to the end portion of the anti-slip material, resulting in poor workability.

On the other hand, the cutting board of the present invention has a configuration in which the end in the width direction of the molding material is provided in the vicinity of the same plane as the cooking surface of the cutting board body, so that the molding material does not hinder the use of the kitchen knife when the cooking surface is used. . In addition, the cooking surface of the cutting board can be kept at a natural height on the countertop.
In the above point, the cutting board of the present invention is different from the cutting board of Patent Documents 1 and 2 in its configuration and effect.

  1st invention WHEREIN: About the positional relationship of a protruding item | line and a ditch | groove, a protruding item | line should just be provided in any one among the adjacent surfaces which a cutting board main body and a molding material face mutually, and a ditch | groove should be provided in the other. In the configuration in which the groove is provided on the cutting board main body and the ridges are provided on the molding material, the ridges are compressed and deformed to fit inside the concave groove, so that the change in the width of the molding material can be kept small. On the contrary, in the configuration in which the ridges are provided on the cutting board body and the groove is provided on the molding material, the ridges of the cutting board body are pushed into the groove and act like the core material of the molding material. The effect of improving the mounting strength is obtained.

[Second invention]
The cutting board of the second invention comprises the configuration of the first invention, and the end of the molding material in the width direction has a width of about 0.5 to 2.5 mm from at least one cooking surface of the cutting board body. It was set as the structure which became the load receiving part which protrudes by and prevents a side slip.

  Usually, the cooking surface of the cutting board is a flat surface. For this reason, when a cutting board is placed on a cooking table with a flat cooking surface facing downward, the cutting board may slide sideways, making cooking difficult.

  In the structure of 2nd invention, since the lower end of the molding material is a load receiving part which protrudes from the cooking surface of a cutting board main body, this load receiving part contacts a base surface and prevents a skid of a cutting board. Thereby, the usability of the cutting board can be further improved.

2nd invention WHEREIN: The height of the said load receiving part is 0.5-2.5 mm from the cooking surface of a cutting board, It is good to restrain to the height of 1-2 mm desirably. With such a height, even if a cutting board is used with the load receiving portion facing upward, the load receiving portion does not interfere with the use of the knife. The present inventors conduct a monitor test using a prototype for the height of the load receiving portion, and determine the height range based on a questionnaire result such as a feeling of use.
The position of the load receiving portion may be any one of the outer circumferences of the cutting board. It may be formed continuously in the length direction of the molding material, or may be formed intermittently apart from each other. When the load receiving portion is provided at a uniform height, the level of the cooking surface is maintained and workability is improved.
In a horizontally long rectangular cutting board, if a load receiving portion is provided only on the short side facing the left and right sides and no load receiving portion is provided on the long side facing the front and rear, the work can be easily performed on both the front and back cooking surfaces.

[Third invention]
A cutting board according to a third aspect of the present invention has the configuration of the first aspect or the second aspect of the present invention, wherein the molding material is formed in an annular shape shorter than the overall length of the outer periphery of the cutting board body, The annular molding material is configured to be tightened by elastic force.

According to such a configuration, since the molding material is annular, the effect (impact mitigation and anti-slip) by the elastic material can be obtained at any part of the outer periphery of the cutting board.
In addition, since the molding material is tightened by the elastic force on the entire outer peripheral side surface (the entire circumference) of the cutting board body, the mounting state of the cutting board body and the molding material is further stabilized, and when using the cutting board, the front, back, left, right, and diagonal directions Even if the molding material is pulled, it becomes difficult for the molding material to come off the cutting board body.

[Fourth Invention]
A cutting board according to a fourth aspect of the present invention comprises the structure according to the third aspect of the present invention, wherein the outer peripheral side surface of the corner of the cutting board main body is a rounded surface that is in close contact with the molding material.

Many general cutting boards are formed so that the corners of the four corners are substantially perpendicular.
When an annular molding material is wound around the outer periphery of the cutting board having such a shape, the molding material may be stretched at the end of the corner portion, and a gap may be generated in the periphery of the molding material to weaken the tightening force of the molding material. .
According to the configuration of the fourth aspect of the invention, the corners of the cutting board body are rounded surfaces that are in close contact with the molding material. An annular molding material can be strongly tightened. As a result, it is possible to obtain a highly reliable cutting board from which the molding material does not easily fall off from the cutting board body.

[First to Fourth Inventions]
In the present invention (first to fourth inventions), the use of the cutting board is not limited, and it may be for home use or for business use.
The material of the cutting board body is preferably a resin such as polyethylene or polypropylene, but may be wood or other materials. As an elastic material of the molding material, elastomer, silicon rubber, soft vinyl chloride, or the like can be used. For the production method, extrusion molding, injection molding or the like can be employed.
As a sales form of the cutting board according to the present invention, the cutting board main body and the molding material are set as a set, and these may be sold separately as a single product. By making it possible to freely change the molding materials of various colors, the range of use can be expanded and the willingness to purchase can be stimulated.
The present invention (first to fourth inventions) may be applied alone or in combination. These inventions may be combined with other inventions described in this specification.

It is a partial expanded sectional view which shows the cutting board by other embodiment.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The cutting board 10 of 1st Embodiment was shown in FIGS. 1-3. 1 is a perspective view of the cutting board 10, FIG. 2A is a plan view thereof, FIG. 2B is a sectional view taken along the line BB of FIG. 2, and FIG. 3 is an enlarged sectional view of a portion III in FIG.

As shown in FIG. 1, the cutting board 10 includes a cutting board body 12 and a molding material 13. An annular molding material 13 is attached along the outer peripheral side surface of the cutting board main body 12.
The cutting board body 12 is formed by forming a resin such as polyethylene or polypropylene with a uniform plate thickness, and has a generally horizontally long rectangular planar shape. A handle hole H is provided in the vicinity of the upper left corner in FIG. The edge portion 12a of the cutting board body 12 and the hole edge portion 12d of the handle hole H are chamfered.

  The molding material 13 is made of an elastic material such as silicon, an elastomer, or soft vinyl chloride, and the surface thereof has a moderate elasticity such that it has a bowl shape and is depressed with a finger. The width of the molding material is uniform and is set to a dimension slightly larger than the thickness of the cutting board body 12.

  The inner peripheral length of the molding material 13 is shorter than the outer peripheral length of the cutting board body 12 in a state where the molding material 13 is removed from the cutting board body 12. As a result, when the molding material 13 is attached to the cutting board body 12, the molding material 13 is fastened to the entire outer peripheral side surface of the cutting board body 12 by its elastic force.

As shown in FIG. 3, the grooves R and the ridges S are provided on the adjacent surfaces 12 b and 13 b of the cutting board body 12 and the molding material 13 facing each other. A concave groove R is formed on the outer peripheral side surface of the cutting board main body 12, and a ridge S is formed on the inner peripheral surface of the molding material 13. By connecting the ridges S to the concave grooves R by elastic force, the molding material 13 can be attached to and detached from the cutting board main body 12.
The concave grooves R and the ridges S are annularly connected along the outer periphery of the cutting board main body 12. The boundary between the two is a laterally U-shaped curved surface, and the adhesion of the coupling surface is enhanced. When the ridge S is fitted into the groove R, the molding material 13 is accurately positioned on the cutting board body 12.

  The corners of the four corners of the cutting board body 12 are arcuate round surfaces M (see FIGS. 1 and 2). The rounded surface M smoothly connects the long side and the short side of the cutting board main body 12 and has a rounded diameter where the cutting board main body 12 and the molding material 13 are in close contact with each other without a gap. As a result, the molding material 13 is stretched at the corners and no gap is generated around the molding material 13, and the concave grooves R and the ridges S are securely fitted over the entire outer periphery of the cutting board main body 12 including the corners.

  As shown in FIG. 3, the upper end of the molding material 13 is positioned substantially on the same plane as the cooking surface f <b> 1 of the cutting board body 12. On the other hand, the lower end of the molding material 13 is at a position protruding downward from the cooking surface f2 of the cutting board main body 12 by a level difference L. That is, the protruding portion at the lower end of the molding material 13 is the load receiving portion 13c. The load receiving portion 13c extends from the cooking surface f2 of the cutting board main body 12 over the entire circumference of the annular molding member 13 with a protruding width of 0.5 to 2.5 mm, preferably about 1 to 2 mm.

  When the molding material 13 is attached to the cutting board main body 12, the molding material 13 is stretched and hung on the outer peripheral side surface of the cutting board main body 12. At this time, the convex strip S of the molding material 13 is fitted into the concave groove R so as to press the molding material 13 against the center side of the cutting board main body 12.

  When removing the molding material 13 from the cutting board body 12, when the molding material 13 is grasped and pulled outward, the ridge S comes out of the concave groove R. When the ridge S is pulled out from the groove R at one location of the molding material 13, the molding material 13 is easily detached from the cutting board body 12 by pulling the molding material 13 by placing fingers with the fingers in the gaps between these parts. If the molding material 13 is removed in this manner, the dirt in the gap between the cutting board body 12 and the molding material 13 can be easily removed.

According to the configuration of the cutting board 10, the outer peripheral side surface of the cutting board main body 12 is covered with the molding material 13, so that the impact by the edge portion 12 a of the cutting board main body 12 is reduced.
Since the end in the width direction of the molding material 13 is kept in the vicinity of the same plane as the cooking surfaces f1 and f2 of the cutting board body 12, the molding material 13 is unlikely to obstruct the use of the knife. In particular, with respect to the cooking surface f1, since the upper end of the molding material 13 coincides on the same plane, the knife edge of the knife does not hit and the cooking operation can be performed comfortably.

  Moreover, according to the cutting board 10, the molding material 13 can be attached to the outer peripheral side surface of the cutting board main body 12 in a stable state without displacement by coupling the concave grooves R and the ridges S with elastic force. Since the annular molding material 13 is clamped to the entire outer peripheral side surface of the cutting board main body 12 with a uniform clamping force, even if the molding material 13 is pulled, it immediately returns to its original state and does not come off easily.

  Further, in the cutting board 10, the molding material 13 serves as a slip stopper. For example, as shown in FIG. 4, when the cutting board 10 is placed on the cooking table with the load receiving portion 13 c of the molding material 13 facing down, the load receiving portion 13 c is pressed against the table surface by the elastic force to prevent the skidding of the cutting board 10. Can do.

Further, as shown in FIG. 5, when the cutting board 10 is leaned against the edge of the kitchen or the like when draining, the outer surface of the bowl shape of the molding material 13 is pressed against the base surface by its elastic force. For this reason, the frictional force between the base surface and the molding material 13 is increased, the skidding of the cutting board 10 is prevented, and the standing posture can be stabilized.
Thus, according to the cutting board 10, since the molding material 13 also plays the role of anti-slip, cooking work and handling during draining are improved.

  Furthermore, according to the cutting board 10, the appearance of the molding material 13 and the cutting board body 12 can be color-coordinated. For example, if a chromatic color such as white, green, red, or blue is used for the cutting board body 12 and green, red, or blue for the molding material 13, the cutting board 10 can be finished with a novel and colorful appearance.

Next, a second embodiment is shown in FIGS. In the following embodiment, the same reference numerals are given to the components corresponding to the components of the first embodiment.
The cutting board 20 of the second embodiment employs linear molding materials 13 and 13. As shown in FIG. 6, two molding members 13 and 13 are attached to both side surfaces of the cutting board main body 12 in the longitudinal direction.
Concave grooves R and ridges S are provided on adjacent surfaces of the cutting board body 12 and the molding material 13 facing each other (see FIG. 7). Grooves R are formed on the cutting board main body 12, and ridges S are formed on the molding material 13, respectively.

  About the shape of the ditch | groove R and the protruding item | line S, it forms so that the boundary of both may become a sideways omega-shaped curved surface. The base portion of the ridge S is a constricted portion Sa, and the constricted portion Sa is in close contact with the return portion Ra near the entrance of the concave groove R (see FIG. 7). On the outer side surfaces of the molding materials 13 and 13, only the upper and lower central portions 13d protrude in a bowl shape.

  When the molding material 13 is attached to the cutting board main body 12, when the ridge S is pushed into the groove R, the ridge S shrinks and fits into the groove R through the return portion Ra. When removing the molding material 13 from the cutting board body 12, if the molding material 13 is pulled outward, the ridge S is once contracted and pulled out from the return portion Ra.

According to the cutting board 20, since the two molding members 13 and 13 can be respectively attached to and detached from the cutting board body 12, cleaning and replacement work can be performed efficiently.
Further, by locking the constricted portion Sa of the ridge S to the return portion Ra of the concave groove R, the attachment strength between the cutting board body 12 and the molding material 13 can be increased.
In the second embodiment, it is of course possible to make the molding material 13 annular.

The cutting board 30 of 3rd Embodiment was shown to FIG. 8 and FIG.
The cutting board 30 of 3rd Embodiment reverses the positional relationship of the ditch | groove R and the protruding item | line S. FIG. A ridge S is formed on the outer peripheral side surface of the cutting board main body 12, and a concave groove R is formed on the inner peripheral surface of the molding material 13 (see FIG. 9). The concave grooves R and the ridges S are connected in a ring shape along the outer periphery of the cutting board 30.

  Two parallel streak-shaped load receiving portions 13c and 13c are formed at both ends of the molding material 13 in the width direction. The load receiving portions 13c and 13c are provided over the entire circumference of the annular molding member 13 with a protruding width of about 0.5 to 2.5 mm, preferably about 1 to 2 mm from the cooking surface f2 of the cutting board body 12 with a uniform spacing. Are connected.

According to the cutting board 30, the convex strip S of the cutting board main body 12 fits into the concave groove S of the molding material 13 and acts like a core material to suppress elastic deformation. For example, as shown by an arrow P in FIG. 9, when a load is applied to the molding material, the load is received by the ridge S to suppress the deformation of the molding material 13 and prevent the groove R from coming off from the ridge S. As a result, the mounting stability of the cutting board body 12 and the molding material can be enhanced.
Further, by side-by-side the two load receiving portions 13c and 13c at both ends of the molding material 13, it is possible to more effectively prevent the skidding of the cutting board 30.
Furthermore, there is an effect that the molding material 13 is more easily bent along the rounded surface of the cutting board body 12 when the groove S is formed than when the molding S is formed on the molding material 13.

A fourth embodiment is shown in FIGS.
In the fourth embodiment, a notch K is provided at a corner of the cutting board 40.
The notch K is provided on one of the four corners on the cooking surface f1 of the cutting board main body 12. The depth and width of the notch K are such that fingers are applied to the upper end of the molding material 13.

  The position of the notch K is outside the handle hole H of the cooking surface f1. Usually, a portion close to the handle hole H on the surface of the cutting board 40 is not used, so that the notch K provided at the above position does not hinder cooking. Other configurations are the same as those in the first embodiment.

  According to the cutting board 40, when removing the molding material 13 from the cutting board main body 12, a finger can be put into the notch K and the upper end of the molding material 13 can be expanded outside. For this reason, the workability of attachment / detachment when removing the molding material 13 from the cutting board body 12 is facilitated, and the usability of the cutting board 40 is improved.

Although 1st-4th embodiment was described, embodiment of this invention may be accompanied by various deformation | transformation, without being limited to these.
The shape of the cutting board body 12 is not limited to a rectangular planar shape, but may be other polygonal shapes, circular shapes, D shapes, or the like.
As long as the shape of the molding material 13 is in close contact with the outer peripheral side surface of the cutting board main body 12, its length and cross-sectional shape can be changed. For example, as shown in a cutting board 50 in FIG. 12, a molding material 13 having a flat side surface 13e may be attached to the cutting board main body 12. With such a configuration, the molding material 13 can be made thinner and lighter to reduce the material cost.
Moreover, as shown in the cutting board 60 of FIG. 13, you may form the load receiving parts 13c and 13c of the molding material 13 intermittently. According to such a configuration, side slip is effectively prevented at the contact surfaces of the load receiving portions 13c and 13c, while the air permeability and water permeability of the cooking surface are enhanced by the intermittent gaps between the load receiving portions 13c and 13c. Can do.
