This chopstick 1 has an engaging means 5 in which the chopstick body 2 and the heat shrink tube 3 are engaged with each other so that the heat shrink tube 3 is not displaced in both longitudinal directions of the chopstick body 2. The chopsticks 1 are used with the heat-shrinkable tube 3 exposed on the surface without applying paint on the heat-shrinkable tube 3 and the portion extending from the heat-shrinkable tube 3 to the chopstick body 2 (that is, the chopsticks). Used).

詳細には、箸本体２は、箸先部６側に向かって先細に形成された先細形状部２ａを有する。そして、その先細形状部２ａと、熱収縮チューブ３における前記先細形状部２ａに密着する先細部分３ａとが、前記係合手段５を構成する第１の係合手段５ａとなり、その第１の係合手段５ａにより、熱収縮チューブ３は、箸先部６側から箸頭部７側へと向かう方向のずれが規制される。また、熱収縮チューブ３は、箸頭部７の天頂面である端面７ａに掛け止められる被掛止部３ｂを有する。そして、その被掛止部３ｂと箸頭部７の端面７ａとが、前記係合手段５を構成する第２の係合手段５ｂとなり、その第２の係合手段５ｂにより、熱収縮チューブ３は、箸頭部７側から箸先部６側へと向かう方向のずれが規制される。 Specifically, the chopstick body 2 has a tapered portion 2a that is tapered toward the chopstick tip 6 side. The tapered portion 2a and the tapered portion 3a in close contact with the tapered portion 2a of the heat shrinkable tube 3 become the first engaging means 5a constituting the engaging means 5, and the first engagement thereof. The joining means 5a regulates the displacement of the heat shrinkable tube 3 in the direction from the chopstick tip 6 side to the chopstick head 7 side. The heat-shrinkable tube 3 has a hooked portion 3 b that is hooked on an end surface 7 a that is the top surface of the chopstick head 7. The hooked portion 3b and the end surface 7a of the chopstick head 7 become the second engaging means 5b constituting the engaging means 5, and the second contracting means 5b allows the heat-shrinkable tube 3 to move. Is restricted in the direction from the chopstick head 7 side toward the chopstick tip 6 side.

具体的には、箸本体２は、木とか竹等からなる天然の木地８に、合成樹脂、例えば無色透明の合成樹脂の木固め剤が摺り込まれて木固めされており、その箸本体２の木固めされた木固め上に前記装飾４が施されている。詳細には、箸本体２は、箸先部６に、本漆による漆付着部あるいは本漆を主体とする漆による漆付着部が形成され、箸先部６を除く部分９（端面７ａを含む）が、前記木固め剤により木固めされている。なお、前記漆付着部には、例えば、顔料とか、乾漆粉あるいはその他の天然素材の粉状物とかが混入されていてもよい。 More specifically, the chopstick body 2 is made of a natural wood material 8 made of wood, bamboo, or the like, and is reinforced with a synthetic resin, for example, a colorless and transparent synthetic resin wood hardening agent. The decoration 4 is applied on two hardened wooden supports. Specifically, the chopstick body 2 is formed with a lacquer adhering portion made of main lacquer or a lacquer adhering portion mainly made of this lacquer on the chopstick tip portion 6, and a portion 9 (including the end face 7 a) excluding the chopstick tip portion 6. ) Is hardened by the wood hardening agent. Note that, for example, pigment, dry lacquer powder, or other natural material powders may be mixed in the lacquer adhering portion.

また、箸本体２は、その全長が前記先細形状部２ａとなって、前記装飾４は、箸先部６を除くようにして（図示実施の形態においては、箸本体２の中央部から箸頭部７に渡って）施される。この装飾４は、例えば、絵、図、画像、記号、模様、文字あるいは色付け等からなり、図示実施の形態においては、装飾４として、雲の絵が描かれている。ここで、装飾４は、絵の具とかポスターカラー等の塗料を用いて描いたり、油性ペン等のペンを用いて描いたり、彫り込みによって描いてもよく、また、シールや写真や紙や布等、あるいは植物の葉等の天然の素材を張り付けたり巻き付けたりするものであってもよい。 Further, the chopstick body 2 has an overall length of the tapered portion 2a, and the decoration 4 is excluded from the chopstick tip portion 6 (in the illustrated embodiment, the chopstick head from the center portion of the chopstick body 2). Applied to part 7). The decoration 4 includes, for example, a picture, a figure, an image, a symbol, a pattern, a character, coloring, and the like. In the illustrated embodiment, a cloud picture is drawn as the decoration 4. Here, the decoration 4 may be drawn using paint such as paint or poster color, drawn using a pen such as an oil-based pen, or engraved, or may be a seal, photograph, paper, cloth, etc. A natural material such as a leaf of a plant may be pasted or wound.

そして、箸本体２は、箸先部６を除く部分９（端面７ａを含む）の所要部が、熱収縮チューブ３によって覆われる。この熱収縮チューブ３は、前述したように、装飾４を覆うように、箸本体２に嵌められ加熱によって収縮密着するが、図示実施の形態においては、熱収縮チューブ３は、木固めした部分（図示実施の形態では、箸先部６を除く部分９）の下部側については覆っていない。そして、木固めした部分の上部側については、熱収縮チューブ３は、箸本体２の周面を覆うとともに箸頭部７の端面７ａを僅かに覆うように延びており、その端面７ａを覆う部分が、前記被掛止部３ｂとなる。つまり、熱収縮チューブ３は、両端が開放した筒状形状となっている。ここで、熱収縮チューブ３は、合成樹脂フィルムからなるが、合成樹脂フィルムよりも厚い合成樹脂シートからなっていてもよい。また、熱収縮チューブ３は、全体が無色透明であるのが好ましいが、有色透明であってもよいし、部分的に模様、記号、文字、色付け等が施されたり描かれたりしていてもよい。 In the chopstick body 2, the required portion of the portion 9 (including the end surface 7 a) excluding the chopstick tip 6 is covered with the heat shrinkable tube 3. As described above, the heat-shrinkable tube 3 is fitted to the chopstick body 2 so as to cover the decoration 4 and is shrunk and adhered by heating. However, in the illustrated embodiment, the heat-shrinkable tube 3 is a hardened part ( In the illustrated embodiment, the lower side of the portion 9) excluding the chopstick tip 6 is not covered. And about the upper side of the hardened part, the heat shrinkable tube 3 extends so as to cover the peripheral surface of the chopstick body 2 and slightly cover the end surface 7a of the chopstick head 7, and covers the end surface 7a. Is the hooked portion 3b. That is, the heat shrinkable tube 3 has a cylindrical shape with both ends open. Here, although the heat contraction tube 3 consists of a synthetic resin film, it may consist of a synthetic resin sheet thicker than a synthetic resin film. The heat shrinkable tube 3 is preferably colorless and transparent as a whole, but may be colored and transparent, or may be partially patterned or drawn with a pattern, symbol, character, coloring, or the like. Good.

次に、以上の構成からなる箸１の作用効果について説明する。この箸１は、箸本体２に透明な熱収縮チューブ３が嵌められ加熱によって収縮密着している。このため、箸本体２は、その箸本体２に施された装飾４を含めて保護される。このとき、箸本体２と熱収縮チューブ３とが互いに係り合う係合手段５により、熱収縮チューブ３は、箸本体２の長手方向の両方向のずれが防止される。そして、このように、直接、箸本体２と熱収縮チューブ３とが互いに係り合うことで、ずれ防止のための、熱収縮チューブ３上とその熱収縮チューブ３から箸本体２に渡る部分への透明塗料等の塗料の塗布が、不要となり、このため、熱収縮チューブ３のずれを簡単に防止することができる。 Next, the function and effect of the chopstick 1 having the above configuration will be described. In this chopstick 1, a transparent heat-shrinkable tube 3 is fitted to a chopstick body 2 and is shrink-contacted by heating. Therefore, the chopstick body 2 is protected including the decoration 4 applied to the chopstick body 2. At this time, the engagement means 5 in which the chopstick body 2 and the heat shrinkable tube 3 are engaged with each other prevents the heat shrinkable tube 3 from being displaced in the longitudinal direction of the chopstick body 2. In this way, the chopstick body 2 and the heat shrinkable tube 3 are directly engaged with each other, so that the chopstick body 2 and the heat shrinkable tube 3 are connected to the chopstick body 2 to prevent deviation. Application of a paint such as a transparent paint becomes unnecessary, and therefore, the displacement of the heat shrinkable tube 3 can be easily prevented.

また、係合手段５が、箸本体２の先細形状部２ａを利用した第１の係合手段５ａと箸頭部７の端面７ａを利用した第２の係合手段５ｂとで構成されることで、箸本体２に特別の細工を施すことなく、前記係合手段５を構成することができる。 Further, the engaging means 5 is composed of a first engaging means 5 a using the tapered portion 2 a of the chopstick body 2 and a second engaging means 5 b using the end surface 7 a of the chopstick head 7. Thus, the engaging means 5 can be configured without any special work on the chopstick body 2.

また、箸本体２は、天然の木地８に合成樹脂の木固め剤が摺り込まれて木固めされている。このため、熱収縮チューブ３が破損したり熱収縮チューブ３および装飾４が破損した場合であっても、その破損部分から箸本体２の木地８に水が浸入するのを防ぐことができ、これによって、箸１の耐久性を容易に向上させることができる。 The chopstick body 2 is hardened by a natural wood base 8 rubbed with a synthetic resin hardener. For this reason, even if the heat-shrinkable tube 3 is damaged or the heat-shrinkable tube 3 and the decoration 4 are damaged, water can be prevented from entering the wood base 8 of the chopstick body 2 from the damaged portion. Thereby, the durability of the chopsticks 1 can be easily improved.

また、箸本体２が、無色透明の合成樹脂の木固め剤により木固めされることで、木固めされた部分のうち装飾４が施されていない部分において、木地８の木目を活かしたままその木地８を保護することができる。 Further, the chopstick body 2 is hardened with a clear and transparent synthetic resin wood hardening agent, so that the wood grain 8 remains utilized in the portion of the hardened portion where the decoration 4 is not applied. The bare wood 8 can be protected.

ところで、箸本体２は、箸１の使用者（購入者）が、箸１に任意の装飾４を施したりすることが可能な、自分好みの箸を製作するための箸素材として用いることができる。すなわち、箸本体２に、前記使用者（購入者）が、絵付け、彫り込み、張り付け、巻き付け等によって任意の装飾４を施すことができる。その後、この箸１は、箸１の製造者または販売者に一旦戻されるとともに、その製造者または販売者が、前記装飾４を覆うように、透明な熱収縮チューブ３を嵌めて、その熱収縮チューブ３を加熱によって収縮密着させる。熱収縮チューブ３は、係合手段５によって、箸本体２の長手方向の両方向のずれが防止される。ここで、熱収縮チューブ３による処理は、短時間で行うことができる。このため、熱収縮チューブ３を用いて装飾４を保護すれば、装飾４を覆うように透明な塗料を塗布する必要がなく、短納期で、使用者（購入者）に、その使用者（購入者）自身が装飾４を施した箸１を提供することができる。ここにおいて、熱収縮チューブ３による処理は、製造者または販売者ではなく、使用者（購入者）自身が行ってもよい。 By the way, the chopstick body 2 can be used as a chopstick material for the user (purchaser) of the chopsticks 1 to make an arbitrary decoration 4 on the chopsticks 1 and to make his / her favorite chopsticks. . In other words, the user (purchaser) can apply an arbitrary decoration 4 to the chopstick body 2 by painting, engraving, pasting, winding, or the like. Thereafter, the chopsticks 1 are once returned to the manufacturer or seller of the chopsticks 1, and the manufacturer or seller fits the transparent heat shrinkable tube 3 so as to cover the decoration 4 and the heat shrinkage thereof. The tube 3 is contracted and adhered by heating. The engagement of the heat shrinkable tube 3 is prevented from shifting in the longitudinal direction of the chopstick body 2. Here, the process by the heat-shrinkable tube 3 can be performed in a short time. For this reason, if the decoration 4 is protected using the heat-shrinkable tube 3, it is not necessary to apply a transparent paint so as to cover the decoration 4, and the user (purchaser) is notified to the user (purchaser) with a short delivery time. The person can provide the chopsticks 1 with the decoration 4. Here, the process by the heat-shrinkable tube 3 may be performed by the user (purchaser) himself, not the manufacturer or the seller.
