【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は誤字修正液、化粧液、インキ等、比較的高粘度の塗布液の塗布具に関 する。さらに詳細には、先端内壁に座部を有する細管を先端部に設け、該細管内 に弁体を配置し、該弁体が、スプリングによって前方に付勢されて前記座部に圧 接されるとともに、一部が細管先端より僅かに前方に突出されてなる塗布具に関 する。 The present invention relates to an applicator for a relatively high viscosity coating liquid such as a typographical error correction liquid, a cosmetic liquid, and an ink. More specifically, a thin tube having a seat portion on the inner wall of the tip is provided at the tip portion, and a valve element is arranged in the thin tube, and the valve element is urged forward by a spring and pressed against the seat portion. At the same time, the present invention relates to an applicator part of which is projected slightly forward from the tip of the thin tube.

【0002】[0002]

【従来の技術】[Prior art]

従来この種の塗布具は、(1)弁体を前方に押圧するスプリングの全体を細管 内に収容する構成、あるいは(2)スプリングによっ前方に付勢された押圧体を 細管内に後方より挿通させ、該押圧体が弁体を前方に押圧する構成が、実開平1 −128875号公報等に開示されている。 Conventionally, this type of applicator has (1) a structure in which the entire spring that presses the valve body forward is housed in the thin tube, or (2) a pressing body that is biased forward by the spring into the thin tube from the rear. A construction in which the pressing body pushes the valve body forward is disclosed in Japanese Utility Model Laid-Open No. 1-128875.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

前記従来の塗布具(1)は、細管内にスプリング全体を収容させるため、スプ リングのコイル部外径を小さくする必要がある。そのため、スプリング全体が小 さくなり、組立作業が細密になって、生産性が低下する。また、スプリングの外 径に制約があるため、自由に所望の弾発力のスプリングを設計し難い。 Since the conventional applicator (1) accommodates the entire spring in the thin tube, it is necessary to reduce the outer diameter of the coil portion of the spring. As a result, the entire spring becomes smaller, the assembly work becomes finer, and the productivity decreases. In addition, since the outer diameter of the spring is limited, it is difficult to freely design a spring having a desired elastic force.

【0004】 また、前記従来の塗布具(2)は、スプリングと押圧体の組立作業の手間を要 すばかりか部品数が増え、製造上コスト高となる。また、前記組立によって弁体 押圧力のばらつきが生じやすい。Further, the conventional applicator (2) not only requires labor for assembling the spring and the pressing body, but also increases the number of parts, resulting in high manufacturing cost. In addition, the assembly tends to cause variations in the pressing force of the valve body.

【0005】 本考案は、前記従来の問題点を解決するものであって、スプリングの組立を簡 略化するとともに、製作が容易な比較的大きな外径のスプリングを採用でき、そ の結果、ばらつきのない安定した弁体押圧力を有する塗布具を提供しようとする ものである。The present invention solves the above-mentioned problems of the prior art by simplifying the assembly of the spring and adopting a spring with a relatively large outer diameter that is easy to manufacture, and as a result, there is a variation. It is an object of the present invention to provide an applicator having a stable valve body pressing force.

【課題を解決するための手段】[Means for Solving the Problems]

本考案塗布具1は、先端内壁に座部21を有する細管2を先端部に設け、該細 管2内に弁体3を配置し、該弁体3が、スプリング4によって前方に付勢されて 前記座部21に圧接されるとともに、一部が細管2先端より僅かに前方に突出さ れてなる塗布具であって 前記スプリング4はコイル部42とストレート部41 により一体に形成され、前記コイル部42が細管2より後方に配置され、前記ス トレート部41が前記細管2内に挿通され、該ストレート部41先端が前記弁体 3を前方に押圧してなることを要件とする。 The applicator 1 of the present invention is provided with a thin tube 2 having a seat portion 21 on the inner wall of the tip at the tip, and a valve body 3 is arranged in the thin tube 2, and the valve body 3 is biased forward by a spring 4. Is an applicator that is pressed against the seat portion 21 and partially protrudes slightly forward from the tip of the thin tube 2. The spring 4 is integrally formed by a coil portion 42 and a straight portion 41. It is required that the coil portion 42 is arranged behind the thin tube 2, the straight portion 41 is inserted into the thin tube 2, and the tip of the straight portion 41 presses the valve body 3 forward.

【0007】 スプリング4は、材料として、ステンレス鋼等の金属、あるいはプラスチック など挙げられる。スプリング4のコイル部42は、巻数は一巻乃至複数巻であり 、形状は円柱、円錐、鼓形、たる形等、いずれであってもよい。また、ストレー ト部41の先端は、弁体3を前方に押圧しやすいように折り曲げたり、膨らませ ることもできる。The spring 4 may be made of metal such as stainless steel or plastic. The coil portion 42 of the spring 4 has one or more turns, and may have any shape such as a cylinder, a cone, a drum shape, and a barrel shape. The tip of the straight portion 41 can be bent or inflated so that the valve body 3 can be easily pushed forward.

【0008】 弁体3は、例えば、ボール、突出部31及びその後部に弁部32を有する弁棒 、あるいは弁部32の後部に流量規制部を配設したもの等、有効である。The valve body 3 is effective, for example, a ball, a valve rod having a protrusion 31 and a valve portion 32 at the rear portion thereof, or a flow rate regulating portion provided at the rear portion of the valve portion 32.

【0009】 ストレート部41先端は、弁体3を前方に押圧すればよく、弁体3に後方より 当接、挿着、係止等いずれの状態であってもよい。The tip of the straight portion 41 may press the valve body 3 forward, and may be in any state such as abutting, inserting and locking the valve body 3 from the rear.

【0010】[0010]

【作用】[Action]

スプリング4がコイル部42とストレート部41により一体に形成されたので 、部品数を減らして、組立作業を簡略化できるとともに、その結果、ばらつきの ない弁体3押圧力を得ることができる。 また、コイル部42を細管2内に収容させないため、コイル部42外径の設計 上の制約が解除され、製作が容易な比較的大きな外径のスプリング4を採用でき る。また、前記大径のスプリング4の採用によって、組立作業がいっそうスムー ズとなる。 Since the spring 4 is integrally formed by the coil portion 42 and the straight portion 41, the number of parts can be reduced, the assembling work can be simplified, and as a result, the pressing force of the valve body 3 without variation can be obtained. Further, since the coil portion 42 is not housed in the thin tube 2, the restriction on the outer diameter of the coil portion 42 is removed, and the spring 4 having a relatively large outer diameter which is easy to manufacture can be adopted. Also, the adoption of the large-diameter spring 4 makes the assembly work smoother.
