JP-A-7-299

複数の層で構成されるまな板は前述したように存在する。まな板は台所で毎日使用されるものであるから使い勝手の良いものが便利である。例えば、まな板は２面あるから一方は臭いの移りやすい魚の調理用として使用するときは、その目印があると便利であり、長さの目盛があるとさらに便利である。また、まな板は板状であるが完全な平面に形成することは困難であって成形時にわずかな変形が生じるのである。このようなまな板を調理台の上に置いて使用するとガタつくので、そのようなガタつきのないまな板があれば使い勝手の良いものになる。さらに、使用後は邪魔になるので片付ける必要があるが、専用のまな板スタンドがなくても壁などに立てかけておくことができれば便利である。本発明はこのような使い勝手の良いまな板を提供することを目的とする。 A cutting board composed of a plurality of layers exists as described above. Since the cutting board is used every day in the kitchen, a convenient one is convenient. For example, since there are two cutting boards, when one is used for cooking fish that easily transfers odor, it is convenient to have the mark, and it is more convenient to have a length scale. Further, the cutting board is plate-shaped, but it is difficult to form it on a completely flat surface, and slight deformation occurs during molding. If such a cutting board is put on a cooking table and used, it will be rattled. Therefore, if there is a cutting board without such rattling, it will be easy to use. In addition, it will be in the way after use, so it needs to be cleaned up, but it is convenient if it can stand against a wall or the like without a dedicated cutting board stand. An object of the present invention is to provide such a user-friendly cutting board.

本発明の請求項１は、芯部材の表面に射出による表層が形成され、表層の材料はゴム弾性を示すプラスチックであり、芯部材の材料は表層の材料よりも硬いプラスチックであるまな板において、まな板の縁に沿って溝が延在し、該溝の内面は芯部材が露出している構成である。 According to a first aspect of the present invention, in a cutting board in which a surface layer is formed by injection on the surface of the core member, the material of the surface layer is a plastic exhibiting rubber elasticity, and the material of the core member is a plastic harder than the material of the surface layer. A groove extends along the edge of the groove, and an inner surface of the groove is exposed.

請求項２は、溝に沿う表層の縁部分が溝の方に変形することを防止するために、溝の内面の両側の上面部も芯部材で形成されている要素が請求項１に付加された構成である。 According to a second aspect of the present invention, in order to prevent the edge portion of the surface layer along the groove from being deformed toward the groove, an element in which the upper surface portions on both sides of the inner surface of the groove are also formed of a core member is added to the first aspect. It is a configuration.

請求項３は、表層が透明又は半透明であり、目盛や図形等の表示がまな板の表面から目視することができ、その表示は芯部材にその表示に該当する凹部又は凸部を設け面一の表層を形成したものである要素が請求項１又は請求項２のいずれか一項に付加された構成である。 According to the third aspect, the surface layer is transparent or translucent, and the display of scales and figures can be visually observed from the surface of the cutting board, and the display is flush by providing the core member with a recess or projection corresponding to the display. The element that forms the surface layer is added to any one of claims 1 and 2 .

請求項４は、まな板の縁部に沿って孔部又は凹部を設けることにより該孔部又は凹部に沿う縁部を把持部とし、該把持部に表層が形成されている要素が請求項１乃至請求項３のいずれか一項に付加された構成である。また、請求項５は、まな板の縁部に沿って孔部が設けられ、孔部を横切って把持部とまな板又はその芯部材とを結ぶ少なくとも一本のブリッジが形成されている要素が請求項４に付加された構成である。 According to a fourth aspect of the present invention, there is provided an element in which a hole portion or a concave portion is provided along an edge portion of the cutting board so that the edge portion along the hole portion or the concave portion serves as a grip portion, and a surface layer is formed on the grip portion. It is the structure added to any one of Claim 3 . Further, claim 5 is an element in which a hole is provided along the edge of the cutting board, and at least one bridge is formed across the hole to connect the gripping part and the cutting board or its core member. 4 is added to the configuration.

請求項６は、芯部材の表面に射出による表層が形成され、表層の材料はゴム弾性を示すプラスチックであり、芯部材の材料は表層の材料よりも硬いプラスチックであるまな板において、まな板表面の縁に沿った部分から突出する少なくとも２つの支持突部が形成され、その少なくとも２つの支持突部間の中央で且つ縁に沿った部分に補助支持突部が形成され、その補助支持突起の高さは支持突部の高さよりも低い構成である。 According to a sixth aspect of the present invention, in a cutting board in which a surface layer is formed by injection on the surface of the core member, the material of the surface layer is a plastic showing rubber elasticity, and the material of the core member is a plastic harder than the material of the surface layer, At least two support projections projecting from the portion along the edge, and an auxiliary support projection is formed at the center between the at least two support projections and along the edge, the height of the auxiliary support projection Is lower than the height of the support protrusion.

請求項１は、芯部材の表面に射出による表層が形成され、表層の材料はゴム弾性を示すプラスチックであり、芯部材の材料は表層の材料よりも硬いプラスチックであるまな板において、まな板の縁に沿って溝が延在し、該溝の内面は芯部材が露出している。溝は庖丁の使用時に食材から出る汁を溜める役目をなす。したがって、使用後は溝に溜まった汁を洗い流したり拭き落としたりする必要があるが、露出している芯部材の表面は摩擦の少ない滑らかな面であるから、汁を容易に取り除くことができる。 In claim 1, a surface layer is formed by injection on the surface of the core member, the material of the surface layer is a plastic exhibiting rubber elasticity, and the core member material is a plastic that is harder than the material of the surface layer. A groove extends along the core, and the core member is exposed on the inner surface of the groove. Grooves serve to collect the juice from the ingredients when using Kenting. Therefore, it is necessary to wash away or wipe off the juice accumulated in the groove after use, but the exposed surface of the core member is a smooth surface with little friction, so that the juice can be easily removed.

請求項２は、溝に沿う表層の縁部分が溝の方に変形することを防止するために、溝の内面の両側の上面部も芯部材で形成されている。したがって、表層の縁部分であって溝の上面に沿う部分が溝の方に変形することを防止する。 According to the second aspect of the present invention, in order to prevent the edge portion of the surface layer along the groove from being deformed toward the groove, the upper surface portions on both sides of the inner surface of the groove are also formed of core members. Therefore, the edge portion of the surface layer and the portion along the upper surface of the groove is prevented from being deformed toward the groove.

請求項３は、表層は透明又は半透明であり、目盛や図形等の表示がまな板の表面から目視することができ、その表示は芯部材にその表示に該当する凹部又は凸部を設け面一の表層を形成したものである。したがって、魚や野菜の図形を表示することによりまな板の２つの面を使い分けることができる。また、目盛や図形に表層が形成されているから、この上に庖丁の刃が当たっても表示が消えることがない。 According to the third aspect, the surface layer is transparent or translucent, and the display of scales and figures can be visually observed from the surface of the cutting board. The surface layer is formed. Therefore, the two faces of the cutting board can be used properly by displaying fish and vegetable figures. Further, since the surface layer is formed on the scale and the figure, the display does not disappear even if the blade of the knife hits on the scale.

請求項４は、まな板の縁部に沿って孔部又は凹部を設けることにより該孔部又は凹部に沿う縁部を把持部とし、該把持部に表層が形成されている。したがって、表層は摩擦抵抗が非常に大きいから把持部に指を掛けることにより滑ることなく確実にまな板を持つことができる。 According to a fourth aspect of the present invention, by providing a hole or a recess along the edge of the cutting board, the edge along the hole or the recess serves as a grip portion, and a surface layer is formed on the grip portion. Therefore, since the surface layer has a very high frictional resistance, it is possible to securely hold a cutting board without slipping by placing a finger on the gripping portion.

請求項５は、まな板の縁部に沿って孔部が設けられ、孔部を横切って把持部とまな板又はその芯部材とを結ぶ少なくとも一本のブリッジが形成されている。ブリッジを設けないで射出成形すると、把持部とまな板又はその芯部材の温度変化時間の相違によって把持部が曲がるのである。したがって、ブリッジ形成することにより把持部の変形を阻止し把持部の曲がっていないまな板を得ることができる。また、離型後にブリッジを取り去れば把持部が曲がっておらず、且つブリッジのない分だけ把持部の持ち易いまな板を得ることができる。 According to a fifth aspect of the present invention, a hole is provided along the edge of the cutting board, and at least one bridge is formed across the hole to connect the gripping part and the cutting board or its core member. When injection molding is performed without providing a bridge, the gripping portion is bent due to a difference in temperature change time between the gripping portion and the cutting board or the core member. Therefore, by forming a bridge, it is possible to prevent the gripping portion from being deformed and to obtain a cutting board in which the gripping portion is not bent. Further, if the bridge is removed after mold release, it is possible to obtain a cutting board in which the grip portion is not bent and the grip portion can be easily held by the amount of no bridge.

請求項６は、芯部材の表面に射出による表層が形成され、表層の材料はゴム弾性を示すプラスチックであり、芯部材の材料は表層の材料よりも硬いプラスチックであるまな板において、まな板表面の縁に沿った部分から突出する少なくとも２つの支持突部が形成され、その少なくとも２つの支持突部間の中央で且つ縁に沿った部分に補助支持突部が形成され、その補助支持突起の高さは支持突部の高さよりも低い構成である。したがって、まな板の中央が沈んだときに補助支持突部により撓みが阻止される。 According to a sixth aspect of the present invention, in a cutting board in which a surface layer is formed by injection on the surface of the core member, the material of the surface layer is a plastic showing rubber elasticity, and the material of the core member is a plastic harder than the material of the surface layer, At least two support projections projecting from the portion along the edge, and an auxiliary support projection is formed at the center between the at least two support projections and along the edge, the height of the auxiliary support projection Is lower than the height of the support protrusion. Therefore, when the center of the cutting board sinks, the auxiliary support protrusion prevents the bending .

まな板の表層１の材料はエラストマーであるがこれに限定されないことは勿論であってゴム弾性を示すプラスチックであれば他の材料であってもよい。硬度は好ましくはショアＡ７０〜８５度程度であるが、この範囲でなくてもよい。また、表層１は半透明であって厚みは１．５ｍｍであるから、芯部材２の表面の表示を目視することができる。厚みがこの数値に限定されないことは勿論である。 The material of the surface layer 1 of the cutting board is an elastomer, but is not limited to this, and other materials may be used as long as the material exhibits rubber elasticity. The hardness is preferably about 70 to 85 degrees Shore A, but may not be in this range. Moreover, since the surface layer 1 is translucent and thickness is 1.5 mm, the display of the surface of the core member 2 can be visually observed. Of course, the thickness is not limited to this value.

芯部材２の材料は表層１よりも硬度の高いポリプロピレンが用いられるがこれに限定されないことは勿論であって、硬度の高いプラスチックであればよく例えばポリエチレン、ポリスチレン、硬質塩化ビニール若しくはＡＢＳ樹脂、又はこれらを混ぜ合わせたものや他の材料を含めて混ぜ合わせたものなどが用いられる。 The core member 2 is made of polypropylene having a hardness higher than that of the surface layer 1, but is not limited to this, and may be any plastic having a high hardness, for example, polyethylene, polystyrene, hard vinyl chloride or ABS resin, or A mixture of these materials or a mixture of other materials is used.

図１に示したようにまな板はほぼ矩形に形成され、各辺は凹の緩やかな円弧状を描いており、まな板を壁面に立てかけたときに辺の両端部のみが流し台の上面に当る。このとき、その辺に表層１が形成されていることによりまな板の滑り止めとなり、立てかけたまな板がずり落ちて倒れる虞がない。また、立てかけたまな板は辺の両端部の２点支持となるのでガタつくことがない。 As shown in FIG. 1, the cutting board is formed in a substantially rectangular shape, and each side has a concave arcuate shape. When the cutting board is leaned against the wall surface, only both end portions of the side hit the upper surface of the sink. At this time, since the surface layer 1 is formed on the side, the cutting board is prevented from slipping, and there is no possibility that the standing cutting board slides down and falls down. Further, the leaning cutting board is supported at two points at both ends of the side, so that it does not rattle.

まな板の四隅には支持突部３が形成されている。図４に示すように支持突部３はその部分の芯部材２を盛り上げて表層１を形成したものであり、まな板の両面に形成されているが片面のみに形成したものであってもよい。支持突部３はほぼ三角形のものが四隅に形成されているが矩形など他の形状であってもよく、まな板の対向する短辺に沿って延在する細長いものを２つ形成してもよい。支持突部３の表面に表層１が形成されることにより滑り止めの効果が生じる。支持突部３の高さは約２．０ｍｍであるがこれに限定されるものではない。 Support protrusions 3 are formed at the four corners of the cutting board. As shown in FIG. 4, the support protrusion 3 is formed by raising the core member 2 of the portion and forming the surface layer 1. The support protrusion 3 is formed on both sides of the cutting board, but may be formed only on one side. The supporting protrusions 3 are substantially triangular in shape at the four corners, but may have other shapes such as a rectangle, or two elongated ones extending along the opposing short sides of the cutting board. . By forming the surface layer 1 on the surface of the support protrusion 3, an anti-slip effect is produced. Although the height of the support protrusion 3 is about 2.0 mm, it is not limited to this.

実施の形態のまな板の長辺は４８０ｍｍで短辺は３００ｍｍである。また、まな板の使用部分の厚みは１２ｍｍであり、このうち芯部材２の厚みは９ｍｍで表層１の厚みは各１．５ｍｍである。しかしまな板はこれらの数値に限定されるものでない。まな板が比較的大きくて長辺の長さが５０ｃｍ程度あるときは、力を入れて硬い物を切るときにまな板が撓むこともある。そこで図１及び図２に示すように両長辺の中央に補助支持突部４が形成されている。補助支持突部４は同じ高さのものが近接して２つ並んでおり、その高さは支持突部よりも低く約１．０ｍｍである。前述したように支持突部３の高さは約２．０ｍｍであるから、まな板の中央が１．０ｍｍ沈んだときに補助支持突部４により撓みが阻止される。１ｍｍ程度の沈みは作業に影響することはない。また、補助支持突部４の長さは約５．０ｍｍで幅は２．０ｍｍである。このように補助支持突部４の幅を小さくした理由は使用中に邪魔にならないようにしたためである。補助支持突部４はまな板の両面に形成してもよく片面のみであってもよい。 The long side of the cutting board of the embodiment is 480 mm and the short side is 300 mm. Moreover, the thickness of the used part of a cutting board is 12 mm, Among these, the thickness of the core member 2 is 9 mm, and the thickness of the surface layer 1 is 1.5 mm each. However, the cutting board is not limited to these values. When the cutting board is relatively large and the length of the long side is about 50 cm, the cutting board may bend when a hard object is cut by applying force. Therefore, as shown in FIGS. 1 and 2, an auxiliary support protrusion 4 is formed at the center of both long sides. Two auxiliary support protrusions 4 having the same height are arranged close to each other, and the height thereof is lower than the support protrusions and is about 1.0 mm. As described above, since the height of the support protrusion 3 is about 2.0 mm, the auxiliary support protrusion 4 prevents bending when the center of the cutting board sinks 1.0 mm. A sink of about 1 mm does not affect the work. The auxiliary support protrusion 4 has a length of about 5.0 mm and a width of 2.0 mm. The reason why the width of the auxiliary support protrusion 4 is thus reduced is that it does not get in the way during use. The auxiliary support protrusions 4 may be formed on both sides of the cutting board or only on one side.

まな板のほぼ全面に表層１が形成されているが長辺の縁に沿って延在する溝５，５の内面６は芯部材１が露出している。また、溝の上面部７も芯部材１で形成されているが、これは溝５に沿う表層１の縁部分が溝５の方に変形することを防止するためである。溝５の幅は約８．０ｍｍであり、最大深さは約１．８ｍｍである。溝５はまな板の両面に形成してもよく片面のみであってもよい。 The surface layer 1 is formed on almost the entire surface of the cutting board, but the core member 1 is exposed on the inner surfaces 6 of the grooves 5 and 5 extending along the edges of the long sides. Further, the upper surface portion 7 of the groove is also formed of the core member 1, in order to prevent the edge portion of the surface layer 1 along the groove 5 from being deformed toward the groove 5. The width of the groove 5 is about 8.0 mm, and the maximum depth is about 1.8 mm. The groove 5 may be formed on both sides of the cutting board or only on one side.

まな板には目盛８が表示されている。図６に示すように目盛８は芯部材２に目盛の凹部を設けて表層１で覆っている。前述したように表層１は半透明であるから、まな板の表面から目盛８として目視できるのである。目盛は２ｃｍ間隔であるがそれ以外の長さ間隔であってもよい。また、必要に応じて目盛に数字を表示して見易くしてもよい。目盛である芯部材２の凹部の深さは約１．０ｍｍであるがこれに限定されるものでない。芯部材２に凸部を設けて目盛としてもよく、芯部材２の表面に塗料などで目盛を描いてもよい。あるいは、別部材を嵌め込んでもよい。凹部又は凸部を設ける場合は製造が容易であり手間がかからない。 A scale 8 is displayed on the cutting board. As shown in FIG. 6, the scale 8 is provided with a scale recess in the core member 2 and covered with the surface layer 1. As described above, since the surface layer 1 is translucent, it can be visually observed as a scale 8 from the surface of the cutting board. The scale is 2 cm apart, but may be other length intervals. Moreover, you may make it easy to see by displaying a number on a scale as needed. The depth of the concave portion of the core member 2 which is a scale is about 1.0 mm, but is not limited to this. A convex portion may be provided on the core member 2 to make a scale, or a scale may be drawn on the surface of the core member 2 with a paint or the like. Alternatively, another member may be fitted. In the case where the concave portion or the convex portion is provided, the manufacturing is easy and it does not take time.

また、まな板には目盛８の他に魚マーク９が表示されている。魚マーク９はそれが表示されたまな板の面が魚用に使用するときの目印である。魚は臭いが残るので他の野菜などと区別して使用したい需要者の要請に応えるためのものである。したがって、まな板の他方の面に例えば野菜マークなどを表示することができる。図５に示すように魚マーク９は芯部材２に魚マークの凸部を設けて表層１で覆っている。表層１は半透明であるから、まな板の表面からこの魚マークの凸部を魚マーク９として目視できるのである。魚マーク９の凸部の高さは約０．７ｍｍであるがこれに限定されるものでない。芯部材２に凹部を設けて魚マークとしてもよく、芯部材２の表面に塗料などで魚マークを描いてもよい。あるいは、別部材を嵌め込んでもよい。魚マーク９の凸部の高さ及び前述した目盛８の凹部の深さは０．５ｍｍ〜３．０ｍｍであることが好ましく、それらの凸部及び凹部を覆う表層１の厚みは０．２ｍｍ〜６ｍｍであることが好ましく、さらに表層１の厚みは凸部の高さあるいは凹部の深さの２倍以下の数値であることが好ましい。 In addition to the scale 8, a fish mark 9 is displayed on the cutting board. The fish mark 9 is a mark when the surface of the cutting board on which it is displayed is used for fish. Since fish has a smell, it is intended to meet the demands of consumers who want to distinguish it from other vegetables. Therefore, for example, a vegetable mark or the like can be displayed on the other surface of the cutting board. As shown in FIG. 5, the fish mark 9 is covered with the surface layer 1 by providing a convex portion of the fish mark on the core member 2. Since the surface layer 1 is translucent, the convex portion of the fish mark can be visually observed as the fish mark 9 from the surface of the cutting board. Although the height of the convex part of the fish mark 9 is about 0.7 mm, it is not limited to this. A recess may be provided in the core member 2 to form a fish mark, or a fish mark may be drawn on the surface of the core member 2 with a paint or the like. Alternatively, another member may be fitted. The height of the convex portion of the fish mark 9 and the depth of the concave portion of the scale 8 are preferably 0.5 mm to 3.0 mm, and the thickness of the surface layer 1 covering the convex portion and the concave portion is 0.2 mm to The thickness of the surface layer 1 is preferably a numerical value not more than twice the height of the convex portion or the depth of the concave portion.

図１に示すようにまな板の一方の短辺に沿って孔部１０を設けることにより把持部１１が形成されている。この把持部１１もほぼ全面的に表層１が形成されており、まな板が濡れていても手が滑りづらいので落とす虞がない。まな板の表面のほとんどの部分はわずかではあるがざらざら面に形成され、境界線１２を境に把手部１１がわの表面は滑らか面に形成されている。ざらざら面に形成した理由は包丁などによる傷を目立たなくするためであり、滑らか面に形成した理由は把持部１１を手で持ったときに感触を良好にするためである。 As shown in FIG. 1, the holding part 11 is formed by providing the hole 10 along one short side of the cutting board. The grip layer 11 is also formed with the surface layer 1 almost entirely, and even if the cutting board is wet, it is difficult for the hand to slide, so there is no risk of dropping. Most parts of the surface of the cutting board are formed in a slightly rough surface, and the surface of the grip portion 11 is formed in a smooth surface with the boundary line 12 as a boundary. The reason why it is formed on the rough surface is to make the scratches due to the kitchen knife inconspicuous, and the reason why it is formed on the smooth surface is to improve the feel when holding the grip portion 11 by hand.

次にまな板の製造方法について説明する。まず、芯部材２を射出により形成する。その際、図７に示すように孔部１０を横切る２本のブリッジ１３も一体に形成する。ブリッジは２本に限定されるものでなく、１本でもよく３本以上でもよい。ブリッジ１３により、射出成形した芯部材２が離型後に生じる把手部１１の外側への反りを防止できる。 Next, the manufacturing method of a cutting board is demonstrated. First, the core member 2 is formed by injection. At that time, as shown in FIG. 7, two bridges 13 crossing the hole 10 are also integrally formed. The number of bridges is not limited to two, but may be one or three or more. The bridge 13 can prevent the warp portion 11 from warping to the outside which occurs after the injection-molded core member 2 is released.

芯部材２が離型した後に、その一方の表面に表層１を射出によって形成する。一方の表面というのはまな板の平らな作業面のみでなく、まな板の４つの辺及び孔部１０の内面の中央まで含む面である。すなわち、まな板の厚みを半分とする片側のまな板の表面に表層１を形成する。ブリッジ１３も一方の表面に表層を形成するが、ブリッジについては表層を形成しなくてもよい。ブリッジ１３を付けたままでまな板とするときは表層１を形成した方が好ましい。また、離型後にブリッジ１３を取り除くときは初めから表層を形成しない方が材料の節約になるので好ましい。次に、まな板のもう一方の表面に同じように表層１を射出により形成する。この後で、ブリッジ１３を根元から切断して取り除く。したがって、完成品にはブリッジ１３の根元部分に芯部材２が露出している。 After the core member 2 is released, the surface layer 1 is formed on one surface thereof by injection. One surface is not only a flat working surface of the cutting board but also a surface including the four sides of the cutting board and the center of the inner surface of the hole 10. That is, the surface layer 1 is formed on the surface of the cutting board on one side whose thickness is halved. The bridge 13 also forms a surface layer on one surface, but the bridge does not have to be formed. When making a cutting board with the bridge 13 attached, it is preferable to form the surface layer 1. Further, when removing the bridge 13 after releasing, it is preferable not to form a surface layer from the beginning because it saves materials. Next, the surface layer 1 is similarly formed by injection on the other surface of the cutting board. After this, the bridge 13 is cut off from the root and removed. Therefore, the core member 2 is exposed at the base portion of the bridge 13 in the finished product.
