Description

本考案は、筒状植物性天然素材の内外面を漆塗装した、ストローに関するものである。  The present invention relates to a straw in which inner and outer surfaces of a tubular plant natural material are lacquered.

ストローは、古くは乾燥した麦の茎などが使用されていた。しかし、石油化学工業の発展に伴い、安価に大量生産できることから、プラスチック製のストローが主流となっていた。プラスチックは、自然界にそのまま廃棄されると、その耐久性から分解され難く、土中や海中に堆積浮遊し、微細化したマイクロプラスチックが土壌や海洋汚染を引き起こし、食物連鎖から、海洋生物が体内にため込む、など地球規模で深刻な環境問題を引き起こしている。使い捨てが主流のプラスチック製ストローも例外ではなく、環境汚染を引き起こさないストローが求められている。  In the past, dried straw stems were used. However, with the development of the petrochemical industry, plastic straws have become mainstream because they can be mass-produced at low cost. When plastic is disposed of in nature, it is difficult to be decomposed due to its durability, and it is deposited and suspended in the soil and the sea. Fine micro plastics cause soil and marine contamination, and marine organisms enter the body from the food chain. It causes serious environmental problems on a global scale, such as the accumulation of energy. Disposable mainstream plastic straws are no exception, and there is a need for straws that do not cause environmental pollution.

ストローが環境汚染を引き起こさないようにする対策として、ストロー原料として天然物からなる素材を使う方法と、自然分解性のプラスチック材料を原料とする方法がとられている。  As measures to prevent the straw from causing environmental pollution, a method using a natural material as a straw raw material and a method using a natural degradable plastic material as a raw material are taken.

しかしながら、従来の考案は、何れも使い捨てを前提とした、耐久性の低い安価なストローであり、廃棄物削減にはつながらない。  However, all the conventional devices are inexpensive straws with low durability on the premise of disposable, and do not lead to waste reduction.

実用新案登録第3219893号Utility model registration No. 3219893 実用新案登録第3220648号Utility model registration No. 3320648 実用新案登録第3221054号Utility model registration No. 3221054

本考案は、以上のような従来の欠点に鑑み、植物性天然素材を使い、耐久性があり繰り返し使用できる、漆塗装ストローの提供を目的とする。  In view of the above-described conventional drawbacks, the present invention aims to provide a lacquered straw that uses a plant natural material and is durable and can be used repeatedly.

植物性天然素材のストローとして使用されてきた、例えば乾燥麦の茎は容易に折れたり潰れてしまい耐久性に乏しい。また、竹を素材としたストローも市販されているが、丈夫ではあるものの、そのままでは飲食物が内外面に染み込み、汚れ、カビが発生する、等の問題が有りやはり使い捨てが前提となっていた。そこで、本考案では、天然の竹を素材として使用し、充分乾燥した後、節が有る場合は節を抜き、更に内外面に漆塗装を施して、繰り返し使用可能なストローを提供する。  For example, dried wheat stalks that have been used as straws for plant natural materials are easily broken or crushed and have poor durability. Straw made of bamboo is also available on the market, but although it is strong, there is a problem that food and drink soaks into the inner and outer surfaces, causing dirt and mold, etc. . Therefore, in the present invention, a straw that can be used repeatedly is provided by using natural bamboo as a raw material, and after sufficiently drying, if there are nodes, remove the nodes and further apply lacquer coating on the inner and outer surfaces.

漆塗装は、古くから漆器として食器に使用されて来たように、通常の食材に対しては耐久性があり、使用後軽く洗浄すれば比較的容易に汚れが落ち、繰り返し使用することが出来る。
一方、漆器は日本を代表する伝統工芸品として、美的に優れ、海外向け贈答品や土産品としても重宝されている。本考案による、漆塗装ストローは、環境汚染と使い捨て文化に一石を投じ、且つ伝統工芸の漆器応用製品として芸術的にも優れている。
Lacquer painting is durable to ordinary foods, as it has been used for tableware as a lacquerware for a long time, and it can be used repeatedly and easily removed by washing lightly after use. .
On the other hand, lacquer ware is aesthetically pleasing as a traditional Japanese craft, and it is also useful as a gift or souvenir for overseas customers. The lacquered straw according to the present invention is an artistic excellence as a product of lacquerware applied to traditional crafts.

以下に、図面を参照しながら本考案を実施するための最良の実施形態について詳述する。  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

本考案の実施例を詳述する。ここでは、筒状植物性天然素材としては竹を用いたが、例えば棒状の植物性天然素材を円筒状に貫通穴を穿ったものを用いても良い。竹には色々な品種があるが、ストローに適した、内径5mmφ前後で長さ20mm前後の竹筒であれば、竹の品種には拘らない。  An embodiment of the present invention will be described in detail. Here, bamboo is used as the cylindrical plant-derived natural material, but, for example, a rod-shaped plant-based natural material having a cylindrical through-hole may be used. There are various varieties of bamboo, but any bamboo varieties can be used as long as they are suitable for straws and have an inner diameter of about 5 mmφ and a length of about 20 mm.

図1は本考案で使用する節のある竹の外観図、図2はその断面図を示す。これらの図に示すように、所定の長さに切り出して内外面を良く洗浄した竹筒において、両端部をそれぞれ吸口側端面1、吸入側端面2とし、竹筒に節3が有る場合には、節3の内部を貫通させて節の内面4を凹凸が無いように綺麗に仕上げストロー状にする。節3は吸口側端面1から三分の一前後に有ると、美的にもバランスが取れ、より好ましい。FIG. 1 is an external view of a bamboo with a node used in the present invention, and FIG. 2 is a sectional view thereof. As shown in these figures, in a bamboo cylinder that has been cut to a predetermined length and the inner and outer surfaces have been thoroughly cleaned, both end portions are the suction side end face 1 and the suction side end face 2, respectively. 3 is penetrated and the inner surface 4 of the node is finished finely so as not to be uneven, and formed into a straw shape. It is more preferable that the joint 3 is located about one-third from the inlet-side end face 1 because it is aesthetically balanced.

また、図3には、節から枝を二本伸ばした竹ストロー素材の例を示した。節3から伸びた枝5はV字状なって、根本から20mm程で切断するのが好ましい。ストローとして使用した際、枝5のV字をグラスの縁に引っ掛けると使い勝手が良い。また、取りだした時、V字を下にしてテーブルに置くと、箸置きのような役割をして好ましい。FIG. 3 shows an example of a bamboo straw material in which two branches are extended from a node. The branch 5 extending from the node 3 is preferably V-shaped and cut at about 20 mm from the root. When used as a straw, it is convenient to use the V-shaped branch 5 on the edge of the glass. Moreover, when taking out, it is preferable to put it on the table with the V-shaped side down, which serves as a chopstick rest.

上記した竹の外表面及び内表面に漆を塗装して、本考案の漆塗装ストローは完成する。The lacquered straws of the present invention are completed by painting lacquer on the outer and inner surfaces of the bamboo.

図4に漆塗装ストローの製造手順を示した。乾燥した原料竹を、ストローサイズに切断し、熱湯で煮沸し油抜きをする。乾燥後節を抜き、節部内面を滑らかに仕上げ、両端面の面取りをする。外面全体を水研き(320番)した後、外面に剥離止め入り漆を塗る。外面を更に細かい600番で水研きし2回目の透き漆塗装をする。2日間乾燥した後600番で水研きをする。竹筒内側穴に漆を流し込み内面を塗装する。内面と両端面を研く。製品の色味に応じて朱或は黒漆を上塗りし、2日間乾燥させる。最後に両端面を塗り乾燥して完成する。  FIG. 4 shows a procedure for manufacturing a lacquered straw. Dried raw bamboo is cut into straw sizes, boiled in hot water and drained. After drying, remove the knot, finish the knot inner surface smoothly, and chamfer both end faces. After the entire outer surface is polished (No. 320), the outer surface is coated with lacquer containing delamination. Polish the outer surface with a finer number 600 and apply the second clear lacquer. After drying for 2 days, we polish with No. 600. Pour lacquer into the inner hole of the bamboo tube and paint the inner surface. Sharpen the inner surface and both end surfaces. Depending on the color of the product, overcoat with vermilion or black lacquer and let dry for 2 days. Finally, both ends are painted and dried.
