Description
本発明は、容器吐出口に取り付ける合成樹脂製塗布ノズルの内容物の硬化防止に関する。 The present invention relates to prevention of curing of the contents of a synthetic resin application nozzle attached to a container outlet.
特許文献1の技術として、シリコンコーキング材が接着しないとともに、ナイフで容易に切断される合成樹脂で形成される中栓付塗布ノズルであって、容器吐出口に装着した雄螺子を有する筒体と、外周に環状突部を有する筒体と、吐出口に連通する通過穴(以下窓孔と表示)を外周に有する筒体と、円錐形中栓を有する円錐形部と、を同軸上に連設させ形成された固定中栓部材に、下部に雌螺子を有する筒体と、内周に前記環状突部に密摺接する摺動部を有する筒体と、前記固定中栓部材に密接する相似形の円錐面を内面とし、外形も円錐形状をなした円錐形塗布ノズルを同軸上に立設した可動ノズル部材を、前記固定中栓部材に、液密に前後進摺動可能に被嵌させ、閉栓時のノズル内の内容物の硬化を防止すると共に、前記中栓に切断容易手段の環状溝を設けるとともに、前記円錐形塗布ノズルは、外面に切断目印環状突部を有し、かつ、0、2mmから5mmの肉厚で形成したことを特徴とする中栓付塗布ノズルが知られている. Patent Literature 1 discloses a coating nozzle with an inner plug formed of a synthetic resin that does not adhere to a silicon caulking material and is easily cut with a knife, and has a cylindrical body having a male screw attached to a container discharge port. A cylindrical body having an annular projection on the outer circumference, a cylindrical body having a passage hole (hereinafter referred to as a window hole) on the outer circumference communicating with the discharge port, and a conical part having a conical inner plug. A cylindrical body having a female screw at the lower part, a cylindrical body having a sliding portion in close contact with the annular protrusion on the inner periphery, and a similar body closely contacting the fixed inner plug member. A movable nozzle member having a conical coating nozzle having a conical surface having an inner surface and a conical outer shape also having a conical shape is coaxially erected on the fixed inner plug member so as to be able to slide forward and backward in a liquid-tight manner. In addition to preventing hardening of the contents in the nozzle at the time of closing, the cutting cap is cut into the inner stopper. In addition to the provision of the annular groove of the means, the conical coating nozzle has a cutting mark annular projection on the outer surface, and is formed with a thickness of 0 to 2 mm to 5 mm. Are known.
また特許文献2に記載の従来の技術として,容器の開口部を閉じるべく容器に装着されるキャップを具え、キャップは、容器と係合するキャップ本体と、容器と係合し且つ容器の開口部を開閉できるようにキャップ本体に接続される蓋体を備え、キャップを容器に装着するときに、キャップを回転させることによりキャップ本体の第1と第2本体部突出部を容器ネジ部に螺合させた後、キャップをさらに回転させることにより容器ネジ部に対する第1と第2本体突出部の螺合を解除して空転させると共に、キャップをさらに回転させることにより蓋体ネジ部が容器ネジ部に螺合完了したときに、キャップが閉位置に位置する様に構成され、キャップを容器に装着する際、容器ネジ部に対する螺合が解除され且つ該容器ネジ部に対して空転させている本体ネジ部を摺接させキャップを閉位置へと案内する案内部を有する構成が知られている。 Further, as a conventional technique described in Patent Document 2, a cap attached to a container to close an opening of the container is provided. The cap includes a cap body engaged with the container, and a cap engaged with the container and an opening of the container. A lid is connected to the cap body so that the cap can be opened and closed. When the cap is mounted on the container, the cap is rotated to screw the first and second main body projecting portions of the cap body into the container screw portion. After that, the cap is further rotated to release the screwing of the first and second main body protruding portions with the container screw portion and idle, and the cap screw portion is further rotated so that the lid screw portion becomes the container screw portion. When the screwing is completed, the cap is located at the closed position, and when the cap is mounted on the container, the screwing on the container screw portion is released and the container screw portion is idled. Construction is known which has a guide portion of the cap is brought into sliding contact with the main body threaded portion for guiding to the closed position.
また、従来の技術として、螺条のネジ溝にネジ溝を横断するように堤を設け、ネジ山の進行を阻止する方法が知られている。(非特許文献) Further, as a conventional technique, there is known a method in which a ridge is provided in a thread groove of a thread so as to cross the thread groove to prevent the screw thread from advancing. (Non-patent literature)
しかしながら、特許文献1に記載の技術では、閉栓時においては、円錐形ノズルを中栓部に対し液密に後進摺動させ、相似形の円錐形中栓と円錐形ノズルとの間隙に残置する内容物を円錐形ノズル内周面と円錐形中栓外周面を全周面にわたり密着させることにより吐出させ、ノズル部内部に湿気が浸透するのを防止し、内容物の硬化防止を図るように構成されているが、内容物には前回使用時に残置され硬化した内容物や塵が混入する可能性があり、また合成樹脂素材の成形時の歪みもあり、全周面を密着させ内容物を完璧に排除し気密状態にすることは難しく、中栓部とノズル部の間に薄く残留した内容物を伝染するように湿気が窓孔内奥部まで浸透し、湿気により硬化するシリコンコーキング材の場合早いときには5日間程で硬化が中栓部内奥部まで浸透し、中栓に対する締め付けが緩めの時にはそれよりもさらに早く硬化が窓孔内奥部に浸透する。それらの原因による硬化時には面倒であっても、中栓部とノズル部を分離させ内奥部の硬化物を除去しなければ注出不可能という致命的な問題があった。また、ノズル部前進時の抜け出し防止ストップ位置が明確では無く、単に螺動が硬くなるだけなのでうっかり強く開栓前進螺動を続けるとノズルが抜け出てしまい塗布作業が中断してしまう問題があった。 However, in the technique described in Patent Document 1, at the time of plugging, the conical nozzle is slid backward and backward in a liquid-tight manner with respect to the inner plug portion, and is left in the gap between the similar conical inner plug and the conical nozzle. The contents are discharged by making the inner peripheral surface of the conical nozzle and the outer peripheral surface of the conical inner plug adhere to each other over the entire peripheral surface to prevent moisture from penetrating inside the nozzle and prevent the contents from hardening. Although it is configured, there is a possibility that the hardened content and dust may be mixed in with the content left in the previous use, and there is also distortion during molding of the synthetic resin material. It is difficult to completely eliminate and make it airtight, and moisture penetrates deep inside the window hole to transmit the thinly-remaining contents between the inner plug and the nozzle, and the silicon caulking material that cures due to moisture If it is early, hardening takes about 5 days. Penetrates into innermost section, at the time of loosening the tightening against the inner plug even more as early curing it penetrates the window hole innermost part. Even if it is troublesome at the time of hardening due to these causes, there is a fatal problem that it is impossible to pour out unless the inner plug portion and the nozzle portion are separated and the hardened material inside the inner portion is removed. In addition, there is a problem that the stopper position is not clear at the time of advancement of the nozzle portion when the nozzle portion is advanced, and the screw is merely hardened. .
次に特許文献2の発明は、キャップを回転させることにより螺合を解除し空転させることによる螺合箇所の切り替えによってキャップを変形した螺旋状のネジ溝より閉位置に案内するものであり、また特許文献2に示される二箇所の突出部に対応するのは本願発明の雌ネジであるが、本願発明の開栓時の空転はノズル部の上昇力を消失させ環状ストッパと共にノズル部の抜け出し防止を図る目的であり、また本願発明の係止案内片は、単に直角三角形状の案内片とによってノズル部の回動係止と逆回動させることにより開栓から閉栓回動へ案内させることであり、内容物の硬化を防止すると共に、硬化時においてはノズル部と中栓部の分解による除去と組立が簡単にできる中栓付塗布ノズルを課題としている本願発明おいては、特許文献2の発明は記述的には当てはまるようではあるが、内容的には異なるものであり、本願発明に採用することは困難であった。 Next, the invention of Patent Document 2 guides the cap to a closed position from a deformed helical thread groove by switching the screwing position by rotating the cap to release the screw and causing the cap to idle, and The two protruding portions shown in Patent Document 2 correspond to the female screw of the present invention, but idling at the time of opening of the present invention eliminates the lifting force of the nozzle portion and prevents the nozzle portion from coming out together with the annular stopper. In addition, the locking guide piece of the present invention is guided from opening to closing by simply rotating the nozzle portion in a reverse direction to the rotation and locking of the nozzle portion with a right-angled triangular guide piece. There is a coating nozzle with an inner plug which can prevent the hardening of the contents and can easily remove and assemble the nozzle portion and the inner plug portion by disassembly at the time of hardening. Departure Although the description seems to be applicable in description, it is different in content, and it has been difficult to adopt it in the present invention.
また、従来技術の雄ネジ部のネジ溝に横断状態に土手状の抜け出し防止の障害物を設けたとしても、中栓部に対しノズル部を使用可能状態にセットする為には土手状の障害物を螺動により乗越えて組立をする必要があり、それが為に障害物の高さをあまり高くすることが出来ないうえに、障害物が摩耗した場合には、力が入る螺動開栓摺動時にはノズル部が簡単に障害物を乗越え抜け出てしまう問題があった。 Also, even if a bank-shaped obstacle to prevent slipping out is provided in the thread groove of the conventional male screw part in a crossing state, the bank-shaped obstacle is required to set the nozzle part to the usable state with respect to the inner plug part. It is necessary to assemble by screwing over the object, so that the height of the obstacle can not be made too high, and if the obstacle is worn, the screw opening to which the power enters will be applied At the time of sliding, there is a problem that the nozzle portion easily gets over the obstacle and slips out.
以上のような従来技術の欠点に鑑み、本発明は、閉栓時のノズル部内の硬化の防止と、また、ノズル部を緩く閉栓した場合に内容物が円錐形ノズル部内周面に薄く硬化した状態においても、窓孔内奥部への硬化の伝染の防止と、また、ノズル部を開栓回動した場合に簡単にノズル部が抜け出す特許文献1の方式および、非特許文献によるネジ溝に横断土手を設ける抜け出し防止方法によらず、耐久性があると共に簡単なノズル部の抜け出し防止方法と、硬化が進行した場合であっても内容物の硬化物除去に伴う分解と組立が簡単に出来る使い勝手のよい中栓付塗布ノズル提供することを課題とする。 In view of the above-mentioned drawbacks of the prior art, the present invention is intended to prevent the hardening of the inside of the nozzle portion at the time of closing, and also, when the nozzle portion is loosely closed, the content is thinly hardened on the inner peripheral surface of the conical nozzle portion. Also, the prevention of the transmission of hardening to the inner part of the window hole, and the method disclosed in Patent Document 1 in which the nozzle part easily comes out when the nozzle part is opened and rotated, and the method disclosed in Non-Patent Document A durable and simple method of preventing the nozzle from slipping out, regardless of the way to prevent the bank from slipping out, and easy to disassemble and assemble with the removal of the hardened material even if hardening has progressed. It is an object of the present invention to provide a coating nozzle with a good inner plug.
本願発明の上下の表記については、容器方向を下部または下とし、ノズル先端の注出口方向を上部または上とすると共に、容器吐出口と連結する装着部側を基端部といい、ノズル部注出口方向を先端部と表記する。 Regarding the upper and lower notations of the present invention, the direction of the container is defined as lower or lower, the direction of the spout at the tip of the nozzle is defined as upper or upper, and the mounting part side connected to the container discharge port is referred to as the base end, The exit direction is referred to as the tip.
また、本願発明においては、図に示すようにノズル部先端吐出口は水平にカットされた状態を前提として説明がなされている。しかしノズル部先端を斜めカットした場合には、閉栓時に中栓先端カットはノズル部先端を越える長さとする。
また、閉栓方向回動は時計回りとし、開栓方向回動は反時計回りと記述する。
なお、本願発明の各々の環状シール部のシールをさせる順序は、先行を大径シール部と想定し、また、内容物はシリコンコーキング材や接着剤の外気によって硬化する粘性の内容物を想定し、またノズル部の前後進摺動は螺動を想定しているが、これらに限定されるものでは無く、内容物によりシール順番を変更することも可能であり、内容物が液体でも適用可能であり、また中栓部に対してノズル部は直線摺動動作でも硬化防止は可能である。
Further, in the present invention, the description is made on the assumption that the discharge port at the tip of the nozzle portion is cut horizontally as shown in the drawing. However, when the tip of the nozzle portion is cut obliquely, the tip of the inner plug at the time of closing is set to a length exceeding the tip of the nozzle portion.
The rotation in the closing direction is described as clockwise, and the rotation in the opening direction is described as counterclockwise.
The order of sealing the respective annular seal portions of the present invention is assumed to be a large-diameter seal portion in advance, and the content is assumed to be a viscous content that is hardened by the outside air of a silicon caulking material or an adhesive. Also, the forward / backward sliding of the nozzle portion is assumed to be screwing, but the present invention is not limited to this. It is also possible to change the sealing order depending on the contents, and it is applicable even if the contents are liquid. Yes, the hardening can be prevented even by linear sliding operation of the nozzle portion with respect to the inner plug portion.
本願発明は、前記の課題を解決するためのものであって、押圧による吐出が可能な容器の吐出口に装着される筒体下部に雄ネジを具え、中部に吐出口に連通する窓孔を有し、上部に円錐形の中栓と、を連設して形成された中栓部に、弾性変形可能な筒体の下部に雌ネジを具え、上部に該中栓に嵌合する円錐形ノズルと、を具えたノズル部を、前後進摺動開閉栓可能に被嵌された中栓付塗布ノズルであって、
中栓部は、同軸上に容器吐出口に装着する装着部と、筒状の雄ネジ部と、雄ネジに螺合する雌ネジ内周面が摺動可能な筒体で形成された空転筒部と、雌ネジ部を弾性拡径させることによる嵌入が可能な高さで形成された環状凸部状の環状ストッパ部と、空転筒部と同径以下の外径の中栓摺動筒部と、中栓摺動筒部外径と同径以下の下端部外径を有し、容器吐出口に連通する窓孔を胴部に具え先端部方向に縮径した円錐台形の円錐台部と、中栓摺動筒部外径より小径の円柱状の円柱部と、円錐形状の中栓と、を連設して構成されており、
The present invention is intended to solve the above-described problems, and has a male screw at a lower portion of a cylindrical body attached to a discharge port of a container capable of discharging by pressing, and a window hole communicating with the discharge port at a middle portion. An inner plug portion formed by connecting a conical inner plug to an upper portion, a female screw at a lower portion of an elastically deformable cylindrical body, and a conical shape fitted to the inner plug at an upper portion. Nozzle, the application portion with an inner plug fitted with a nozzle portion comprising a, forward and backward sliding openable and closable plug,
The inner plug portion is formed of a mounting portion mounted coaxially to the container discharge port, a cylindrical male screw portion, and an idling cylinder formed of a cylindrical body in which an inner peripheral surface of a female screw screwed into the male screw is slidable. Portion, an annular stopper portion having an annular convex shape formed at a height at which the female screw portion can be fitted by elastically expanding the diameter, and an inner plug sliding cylinder portion having an outer diameter equal to or less than the diameter of the idling cylinder portion. A frusto-conical portion having a lower end outer diameter that is equal to or less than the outer diameter of the inner stopper sliding cylinder portion and having a window hole communicating with the container discharge port in the body portion and having a diameter reduced toward the distal end portion. , An inner plug sliding cylindrical portion, a cylindrical column having a diameter smaller than the outer diameter, and a conical inner plug, are configured in series,
ノズル部は、雄ネジ部外径と内径が略同径の筒体内周面下部に雄ネジと螺合する雌ネジを突設した雌ネジ筒部と、中栓摺動筒部外周面に液密または気密に摺動可能な大径摺動筒部と、連結筒体を介して内周面が円柱部に液密または気密に摺動可能な小径摺動筒部と、円錐形状のノズルと、を同軸上に連設して形成されている構成とする。 The nozzle part has a female screw cylinder part with a female screw protruding from the lower part of the inner peripheral surface of the cylinder whose outer diameter and inner diameter are approximately the same diameter, and a liquid on the outer peripheral surface of the inner stopper sliding cylinder part. A large-diameter sliding cylinder that can slide tightly or air-tightly, a small-diameter sliding cylinder that can slide liquid-tight or air-tight on a cylindrical portion through a connecting cylinder, and a conical nozzle. , Are formed coaxially and continuously.
かかる構成によれば、中栓部に対しノズル部が下降する閉栓摺動時においては、中栓摺動筒部と円柱部の上端外縁部により、大径摺動筒部と小径摺動筒部の内周面に付着した内容物が削ぎ取られると共に液密または気密の環状シール部が各々に形成されている構成とした。 According to this configuration, at the time of stopper sliding in which the nozzle portion descends with respect to the inner plug portion, the large-diameter sliding cylinder portion and the small-diameter sliding cylinder portion are formed by the inner stopper sliding cylinder portion and the outer edge of the upper end of the cylindrical portion. The contents adhered to the inner peripheral surface of each of the above were scraped off, and a liquid-tight or air-tight annular seal portion was formed on each.
次に、閉栓時においては、さらに密封度を高めるためにノズル部をさらに閉栓回動させることにより、大径摺動筒部と小径摺動筒部の内周面に各々に設けられた環状凸部を、中栓摺動筒部と円柱部との間に介在位置させ、より密封度の高い環状の大径シール部と小径シール部が形成されていることを特徴とする構成とした。 Next, at the time of closure, the nozzle portion is further closed and rotated in order to further increase the sealing degree, so that the annular convex portions provided on the inner peripheral surfaces of the large-diameter sliding cylinder portion and the small-diameter sliding cylinder portion, respectively. The part is interposed between the inner stopper sliding cylinder part and the cylindrical part, and an annular large-diameter seal part and a small-diameter seal part having a higher degree of sealing are formed.
また、閉栓時の円錐形ノズルと円錐形中栓とのノズル部先端部嵌合においては、ノズル部の円錐形頂角は該中栓部の円錐形頂角よりも広角に形成されており、円錐形中栓外周面と円錐形ノズル内周面との当接時には環状のシール部が形成されていることを特徴とする構成とした。 In addition, in the fitting of the nozzle tip portion of the conical nozzle and the conical inner plug at the time of closure, the conical apex angle of the nozzle portion is formed to be wider than the conical apex angle of the inner plug portion, When the outer peripheral surface of the conical inner plug and the inner peripheral surface of the conical nozzle are in contact with each other, an annular seal portion is formed.
次に、環状ストッパ部は、ノズル部雌ネジ部が開栓方向螺動により上昇し螺脱すると共に、空転筒部に入域し、空転回動状態になった雌ネジ部の螺条先頭部上側が当接する位置に配置されると共に、環状ストッパ部下側に、平面視形状が直角三角形状の係止案内片の一辺を密接させ周設形成すると共に、他の一辺は軸方向と平行に雌ネジ部の螺条先頭部の開栓回動係止壁として位置させ、斜辺はノズル部閉栓方向回動において、雌ネジ螺条先頭部上側が斜辺下側に当接摺動するのに伴う下降回動を案内すると共に、雌ネジ螺条後尾部が雄ネジ部に螺合を開始させる案内辺としても形成されており、雌ネジ部の上昇係止と、回動係止と、閉栓螺動案内の機能と、を空転筒部上部外周に一体に周設形成させていることを特徴する構成とした。 Next, the annular stopper portion is configured such that the female screw portion of the nozzle portion rises by the opening direction screwing and unscrews, and enters the idling cylinder portion, and the leading end of the threaded portion of the female screw portion which is in the idling rotation state. The upper side is disposed at a position where it contacts, and one side of the locking guide piece having a right-angled triangular shape in plan view is closely formed and formed under the annular stopper, and the other side is formed in parallel with the axial direction. The screw head is positioned as the opening rotation stop wall of the screw head, and the oblique side is lowered as the upper part of the female screw thread comes into contact with the lower side of the oblique side when rotating in the nozzle closing direction. In addition to guiding the rotation, the rear end of the female screw thread is also formed as a guide side for starting screwing with the male screw part. The guide function and the outer periphery of the upper portion of the idling cylinder are integrally formed around the idler cylinder.
本発明の閉栓時においては、閉栓第1段階として、窓孔部の上部と下部の二箇所に液密または気密の小径と大径の環状シール部が形成され、閉栓第2段階として、円錐形ノズルと円錐形中栓とにより、円錐形ノズル先端に環状シール部を形成させる構成であり、閉栓時においてノズルを例え緩く締めた状態であっても、既に窓孔部は上下に形成された環状シール部により密封されており、硬化は円錐形ノズル部の内周面に薄く発生するのみで窓孔部内奥に進行しないため、ひき続き注出は可能であり、次の使用に支障はきたさない構成とした。 At the time of closure according to the present invention, a liquid-tight or air-tight small-diameter and large-diameter annular seal portion is formed at two places, an upper part and a lower part, of a window hole as a first stage of closure, and a conical shape is formed as a second stage of closure. With the nozzle and the conical inner plug, an annular seal portion is formed at the tip of the conical nozzle, and even when the nozzle is loosely tightened when the plug is closed, the window hole is already formed in the upper and lower annular It is sealed by the seal part, and hardening occurs only thinly on the inner peripheral surface of the conical nozzle part and does not proceed deep inside the window hole part, so it can be continuously poured out and does not hinder the next use Configuration.
次に、円錐形ノズル部のシール方式に於いては、前記ノズル先端に環状シールを形成させることにより、特許文献1の全周面的に密着する方式と比較しノズル及び中栓の成形時の歪みがあったとしても、その影響は減少し、また密着部分の面積の減少に伴い単位面積当たりの密着圧も高まるとともに気密性も高めた。 Next, in the sealing method of the conical nozzle portion, by forming an annular seal at the tip of the nozzle, compared with the method in which the nozzle and the inner plug are tightly adhered to the entire peripheral surface of Patent Document 1, Even if there is a distortion, the influence is reduced, and with the decrease in the area of the contact portion, the contact pressure per unit area is increased and the airtightness is also increased.
また、中栓部に対してノズル部の密着圧力を強化することにより、ノズル部摺動時及び閉栓時おいては液密または気密性は高まるが、摺動時においては回動摺動動作が重くなる難点が生じ、また密着圧力を緩和することにより摺動回動動作は軽快にはなるが、摺動時の密封度は下がってしまう、これらを補い内容物の硬化の可能性の高い保管時の硬化を防止するために、該ノズル部閉栓時において、中栓摺動筒部上部外周と該円柱部上部外周に当接した大径摺動筒部と小径摺動筒部の内周面位置に環状凸部を介在配置させた構成により、密封性をより高めた。 In addition, by strengthening the pressure of the nozzle against the inner plug, the liquid-tightness or air-tightness is improved when the nozzle is slid and when the nozzle is closed, but the rotational sliding operation is performed during the sliding. Difficulty of becoming heavy, and by reducing the contact pressure, the sliding and rotating operation becomes lighter, but the sealing degree during sliding is reduced. In order to prevent hardening at the time, when the nozzle portion is closed, the inner peripheral surfaces of the large-diameter sliding cylinder portion and the small-diameter sliding cylinder portion abutting on the upper outer periphery of the inner stopper sliding cylinder portion and the upper outer periphery of the cylindrical portion. The configuration in which the annular convex portion is interposed at the position improves the sealing performance.
また、ノズル部の閉栓時において、大径摺動筒部下部の肉厚部が中栓摺動筒部下部に周設された帯状環状凸部に乗り上げ密封させる構成とし、窓孔部下部に環状シール部が2カ所形成されることにより密封性をさらに高めた。 Also, when closing the nozzle portion, the thick portion at the lower part of the large-diameter sliding cylinder portion rides on a band-shaped annular convex portion provided around the lower portion of the inner-plug sliding cylinder portion and seals it. The sealability is further improved by forming two seal portions.
また、ノズル部開栓上昇時には、ノズル部雌ネジが螺脱し、空転回動状態になり、上昇力を失ったノズル部の上昇は停止されると同時に雌ネジは環状ストッパ部に当接し、上昇力を失った雌ネジ部は環状ストッパ部に当接するだけでノズル部の上昇が阻止されることにより、環状ストッパ部の摩耗による係止能力の減少が軽滅され。長期の使用に耐えられ、またノズル部を手動により上部に引き抜くように回動させることにより雌ネジが乗越え可能な高さの環状ストッパを乗越え、簡単に中栓部とノズル部が分離され、硬化時の内容物除去が容易になる。 In addition, when the nozzle is opened, the female screw of the nozzle is unscrewed and idles, and the nozzle which has lost the lifting force is stopped from rising. Since the female screw portion which has lost the force only comes into contact with the annular stopper portion, the rise of the nozzle portion is prevented, so that the decrease in the locking ability due to the wear of the annular stopper portion is reduced. It can withstand long-term use, and it can be rotated by pulling the nozzle part upwards by hand. The contents can be easily removed at the time.

まず、図7に示す閉栓時の状態から、中栓部に対しノズル部の反時計回りの螺動により、雌ネジ部21は上昇し、螺合を離脱すると略同時に空転筒部16領域に上昇力を喪失した摺接回動状態で入域し、環状ストッパ部15と雄ネジ上端を平面状にカットした雄ネジ平面カット部17との間を空転回動状態になった雌ネジのネジ山先頭部が、図9に示すように、乗越え可能な高さで形成された係止案内片15aに衝突するが、ノズル部を中栓部から引き抜くような回動動作を行わない限り、環状ストッパ部15に上昇を阻止されると共に、係止案内片15aにより回動も係止され、あるいは乗越えられるが、前記したように引き抜くような回動動作を行わない限り、上昇力を喪失したノズル部が抜けることは無い、この時に、使用者は係止を感知しノズル部が開栓注出可能状態に達したことを自覚し、ノズル部回動を停止させノズルは開栓塗布状態になる。(矢印方向は開栓開始時を表す)
Next, an embodiment from a plugged state to a plugged out state and a plugged state will be described with reference to the drawings.
First, from the closed state shown in FIG. 7, the female screw portion 21 rises by the counterclockwise screwing of the nozzle portion with respect to the inner stopper portion, and rises to the idling cylinder portion 16 region almost at the same time when the screwing is released. The female thread which enters the area in the sliding contact rotation state where the force has been lost, and is in the idling rotation state between the annular stopper portion 15 and the male screw plane cut portion 17 in which the upper end of the male screw is cut in a plane. As shown in FIG. 9, the leading end collides with a locking guide piece 15a formed at a height which allows the head to climb over, but unless the rotary operation is performed so as to pull out the nozzle portion from the inner plug portion, an annular stopper is formed. The nozzle portion is prevented from ascending by the portion 15 and the rotation is also locked or moved over by the locking guide piece 15a, but the nozzle portion which has lost the lifting force unless the pulling operation is performed as described above. Does not come off, at this time the user senses the lock Aware that the nozzle unit has reached the cap removal pourable state, the nozzle stops the nozzle unit rotates becomes unplugging coated state. (The direction of the arrow indicates the start of opening)
次に、容器への押圧により容器に充填された内容物は中栓部筒体を通過し、窓孔13から吐出され(図4、図6)ノズル部と中栓部との間隙10aを通過しノズル先端から注出され塗布使用される。 Next, the contents filled in the container by pressing the container pass through the inner plug cylindrical body and are discharged from the window 13 (FIGS. 4 and 6) and pass through the gap 10a between the nozzle portion and the inner plug portion. It is discharged from the nozzle tip and used for coating.
次に、開栓塗布状態から閉栓保管状態への実施形態を、図7〜図9を参照して説明する。
塗布作業終了後、ノズル部を時計回りの閉栓回動をさせ、図8に示すように、まず雌ネジ21先頭部上側が係止案内片15a斜辺に当接案内され、雌ネジ21後尾部が雄ネジ18螺条先端部に螺合され、ノズル部は螺動により下降を始める。
Next, an embodiment from the open application state to the closed storage state will be described with reference to FIGS.
After the coating operation is completed, the nozzle portion is turned clockwise to close the stopper. As shown in FIG. 8, first, the upper end of the female screw 21 is guided in contact with the oblique side of the locking guide piece 15a. The male screw 18 is screwed to the tip of the thread, and the nozzle starts to descend by screwing.
また、同時にノズル部を構成する大径摺動筒部22と小径摺動筒部23も摺動下降すると共に、該中栓摺動筒部14と該円柱部11の上部外縁により該大径摺動筒部22内周面と該小径摺動筒部23内周面に各々付着した内容物が削ぎ落され、液密または気密状態になった大径摺動筒部22と中栓摺動筒部14、そして、小径摺動筒部23と該円柱部11との間に、挟みこむように大径摺動筒部22と小径摺動筒部内周面に設けた(図5参照)大径環状凸部24と小径環状凸部25により、内容物の環状凸部への巻き込みを減少させると共に、窓孔部13対する密封性をより高めた図5に示す環状シールが形成される。 At the same time, the large-diameter sliding cylinder portion 22 and the small-diameter sliding cylinder portion 23 constituting the nozzle portion also slide down, and the large-diameter sliding cylinder portion 14 and the upper outer edge of the cylindrical portion 11 form the large-diameter sliding cylinder. The large-diameter sliding cylinder portion 22 and the inner-plug sliding cylinder which are liquid-tight or air-tight are formed by removing contents attached to the inner peripheral surface of the moving cylinder portion 22 and the inner peripheral surface of the small-diameter sliding cylinder portion 23, respectively. The large-diameter annular portion is provided between the large-diameter sliding cylinder portion 22 and the small-diameter sliding cylinder portion so as to be sandwiched between the portion 14 and the small-diameter sliding cylinder portion 23 and the cylindrical portion 11 (see FIG. 5). The convex portion 24 and the small-diameter annular convex portion 25 form an annular seal shown in FIG. 5 in which the content is reduced from being caught in the annular convex portion and the sealing performance of the window hole 13 is further improved.
次には、ノズル部最先端においては,図3に示すように円錐形中栓10と円錐形ノズル26とにより、環状シールが形成されると共に、さらに図1に示すように大径摺動筒部下部の肉厚部22aが中栓摺動筒部下部に周設された帯状環状凸部14aに乗り上げ密封させることにより密封性をさらに高めた構成とした。 Next, at the tip of the nozzle portion, an annular seal is formed by the conical inner plug 10 and the conical nozzle 26 as shown in FIG. 3, and a large-diameter sliding cylinder as shown in FIG. The thick part 22a at the lower part of the lower part slides over the belt-shaped annular convex part 14a provided around the lower part of the inner plug sliding cylinder part, and the sealing is further improved by sealing.
