明 糸田 弁付塗布具の塗布先 技 術 分 野  Akira Itoda Applicator with valve
本発明は、 粘度が 5 0〜 1 5 0 c P S の修正液、 塗料、 化粧料、 イ ンキ等の塗布液を収納した弁付塗布具の塗布先 に闋し、 特に細い線状の塗布を行なう のに好適なよう に先 体を金属製管状体で形成した弁付塗布具の塗布先に関する ものである。 背 景 技 術 The present invention has a viscosity 5 0~ 1 5 0 c PS correction fluids, paints, cosmetics, and闋the application destination of coating liquid accommodating the valved applicator such as Lee Nki, especially thin linear coating The present invention relates to an application destination of a valve-equipped applicator in which a tip is formed of a metal tubular body so as to be suitable for performing. Background technology
従来、 塗布液室を内部に有する本体と、 該本体の先部に 固着された先体と、 塗布部を前記先体の先端孔ょ リ突出し かつ、 弁部を先体の先端孔内方の座部に圧接するよ う前方 に付勢されてなる弁体とよ りなる弁付塗布具が知られてい る。  Conventionally, a main body having a coating liquid chamber inside, a forebody fixed to the front part of the main body, a coating part protruding from the front end hole of the forebody, and a valve part being provided inside the front end hole of the forebody A valve-equipped applicator comprising a valve body urged forward to press against a seat is known.
この種の弁付塗布具は、 弁体を後方に移動させた時、 塗 布液が座部と弁都との間隙を通過し、 先体先端孔と塗布部 との間隙から流出する構造であるので、 比較的幅狭の塗布 跡が得られる という特徴を有しているが、 近年、 市場にお いては更に細い塗布跡を得られる弁付塗布具が求められて いる。  This type of valve-equipped applicator has a structure in which when the valve is moved backward, the coating liquid passes through the gap between the seat and the valve, and flows out from the gap between the tip end hole and the applicator. Therefore, it has the characteristic that a relatively narrow coating mark can be obtained, but in recent years, there has been a demand in the market for a valve-coated coating tool capable of obtaining a finer coating mark.
塗布跡を細くするには、 先体の先端を細く した り、 先体 先端孔を小さ くすれば良い。 しかしながら、 この場合先端 部分の肉厚を非常に薄いものとせざるを得ないため、 強度 や腐食性の点から材料と してステン レス等の耐食性金属材 料を用いる必要が有リ、 管状体とするための加工方法と し て、 一般的には旋削加工 （即ち、 加工物及び/又は刃物を 回転させながら行なう加工） が採用される。 To narrow the trace of application, the tip of the forehead may be made thinner or the forehead tip hole may be made smaller. However, in this case the tip Since the thickness of the part must be very thin, it is necessary to use a corrosion-resistant metal material such as stainless steel from the viewpoint of strength and corrosiveness. As a general rule, turning (that is, processing performed while rotating a workpiece and / or a cutting tool) is employed.
ところが、 例えば旋削加工によ り形成された座部表面に は、 旋削挽き跡目や、 切 り粉等による傷、 ビビリ跡 （切削 加工時、 刃が振動して、 深く切れたと ころと浅く切れたと ころとが波のよう になる現象） 等の要因による微細な凹凸 が有り、 このため弁座と弁部との密閉が不十分となり、 塗 布先よ りの塗布液の漏れが発生し易くなる。  However, for example, on the surface of the seat formed by turning, marks such as turning marks, scratches due to cutting chips, etc. There is fine irregularities due to factors such as the roller becoming a wave), which makes the sealing between the valve seat and the valve part insufficient, and the coating liquid leaks more easily from the coating destination .
弁座と弁部との当接部を例えば鏡面となし完全な密閉状 癰を形成すれば塗布液の漏れは発生しない。 しかしながら、 弁部については外面の加工であるため、 その表面を平滑に 加工する ことは可能であるものの、 特に座部に関しては内 面の加工であ り、 上記の要因のため完全な密閉状態を形成 するよう加工を行なう ことは非常に困難な事であ り、 塗布 液の漏れを完全には無くせないという問題がある。 発 明 の 開 示  If the contact portion between the valve seat and the valve portion is made, for example, a mirror surface to form a complete hermetic carbuncle, the leakage of the coating liquid does not occur. However, since the valve is an outer surface, it is possible to smooth the surface.However, especially the seat is an inner surface. It is very difficult to perform the processing to form, and there is a problem that the leakage of the coating solution cannot be completely eliminated. Disclosure of the invention
本発明の 目的は、 空気流量と塗布液漏れとの相閧闋係に 鑑み、 弁座と弁部との弁機構部が完全な密閉状態でなく と も、 実用上、 塗布液漏れの発生しない弁付塗布具の塗布先 を提供するこ とである。 本発明の要旨は、 先端孔後端内方 に座部を形成した金属製管状先体と、 先端孔よ り塗布部を 突出させ、 前記座部に弁部を圧接するよう前方に付勢され た弁体と よ り なる弁付塗布具の塗布先であって、 この塗布 先の閉弁時の空気流量を、 空気圧 1 .

上記実施例で得た塗布先各々 1 0本を用いて弁付塗布具 を組み立て、 塗布液と して修正液 （製品符号 ； Z L 3 1 — W : ぺんてる㈱製 ： 粘度 1 1 0 c p s ， 2 5 °C) に使用さ れている液を充填し、 弁付塗布具の本体雨側面に 3 kgの加 重をかけ、 5分後、 塗布先からの塗布液の漏れ状態を 1 0 本のサンプルにっき観察し塗布液漏れの試験を行なった。 結果を下表 1に示す。 Assembling an applicator with a valve using each of the 10 applicators obtained in the above example, and using a correction fluid as the coating fluid (product code: ZL31—W: Pentel: Viscosity: 110 cps, 2 (5 ° C), and add 3 kg to the rain side of the main body of the applicator with valve. Five minutes after the application of weight, the state of leakage of the coating liquid from the coating destination was observed on 10 samples, and a test of the coating liquid leakage was performed. The results are shown in Table 1 below.
