Description
本発明は、噴出ノズル管の挿入を補助する補助管に関し、詳しくは、噴出ノズル管の噴出口を備える先端を中空に浮かせた状態に保持するための補助管に関するものである。 The present invention relates to an auxiliary pipe for assisting insertion of an ejection nozzle pipe, and more particularly to an auxiliary pipe for holding a tip provided with an ejection outlet of the ejection nozzle pipe in a state of floating in a hollow state.
スプレー・エアゾールといったものの構造において、スプレー缶・エアゾール缶には内容物のほか該内容物を噴出するためのＬＰＧ・ブタン等液化ガスや窒素・炭酸・空気等のガスが封入され、缶の上方に設けられた噴出ノズルや、あるいは、該噴出ノズルに更にノズル管を取り付けて該ノズル管の先端部に設けた開口を噴出口として、缶内の内容物が噴出される構造となっている。 In the structure of sprays and aerosols, in addition to the contents, spray cans and aerosol cans are filled with liquefied gas such as LPG or butane, or nitrogen, carbonic acid, air, etc. The structure is such that the contents in the can are ejected using the ejection nozzle provided, or an opening provided at the tip of the nozzle tube by further attaching a nozzle tube to the ejection nozzle.
後者、すなわちノズル管を取り付けて内容物を噴出する場合において、該ノズル管の問題として、内容物の噴出先が狭いスペースであったり、その先端部を所定管内等に挿入して噴出を行うような場合に、ノズル管先端が噴出先壁面等の対象物に接触した状態で噴出が行われてしまうことがあった。すなわち、スプレー缶等の内容物を噴出先に満遍なく行き渡らせるためには、該内容物とガスとが混合状態のまま噴出される必要があるが、ノズル管先端が噴出先対象物に接触状態である場合、噴出口から噴出された内容物とガスとの混合物が噴出先壁面等に当たることで液化され、結果として内容物が噴出先壁面等に付着した状態となって、噴出先に満遍なく行き渡らせることができないという問題があった。 In the latter case, that is, when a nozzle tube is attached and the contents are ejected, as a problem of the nozzle tube, the contents are ejected in a narrow space or the tip is inserted into a predetermined tube or the like for ejection. In some cases, ejection may be performed in a state where the tip of the nozzle tube is in contact with an object such as a wall surface of the ejection destination. That is, in order to spread the contents such as spray cans evenly over the ejection destination, the contents and the gas need to be ejected in a mixed state, but the nozzle tube tip is in contact with the ejection target object. In some cases, the mixture of contents and gas ejected from the ejection port is liquefied by hitting the ejection destination wall surface, etc., and as a result, the contents adhere to the ejection destination wall surface and spread throughout the ejection destination. There was a problem that I could not.
かかる問題の具体例として、現在生産され使用されている自動車の吸入系から燃焼室に付着したカーボン汚れを除去する場合が挙げられる。すなわち、かかる吸入系には、ブローバイガスとともに運ばれてきたカーボンおよびスラッジが吸入管内部に付着してアイドリングの不調現象が発生したり、また、燃焼室内部には、ピストンヘッドをはじめピストンリングや吸入排気バルブおよびシリンダーヘッドなどにカーボン汚れが付着することで、噴射された燃料を前記カーボン汚れが吸着してしまい、燃焼遅れや不完全燃焼が発生することは、周知の事実である。したがって、前記カーボン汚れを除去することが機能・性能の回復に非常に有効となるため、従来より種々の方法にて該カーボン汚れを除去する試みが行われているが、その中でも一般的主流の方法としてはカーボン汚れを除去する洗浄液を吸入系から噴射する方法であり、その具体的方法はノズル管を吸入系に挿入して洗浄液を噴射するというものである。しかしながら、当該方法によると、上記した問題があるため、洗浄液が満遍なく行き渡ることなく、偏った部分にだけ効果を発揮するのみであった。 As a specific example of such a problem, there is a case where carbon dirt adhering to the combustion chamber is removed from an intake system of an automobile currently produced and used. That is, in such an intake system, carbon and sludge carried together with the blow-by gas adhere to the inside of the intake pipe, and an idling malfunction occurs. In addition, the piston head, piston ring, It is a well-known fact that carbon dirt adheres to the intake / exhaust valve, cylinder head, etc., causing the carbon dirt to adsorb the injected fuel, resulting in combustion delay and incomplete combustion. Therefore, since the removal of the carbon stains is very effective for the recovery of the function and performance, attempts have been made to remove the carbon stains by various methods. As a method, a cleaning liquid for removing carbon stains is sprayed from the suction system, and a specific method is to insert the nozzle tube into the suction system and spray the cleaning liquid. However, according to this method, there is the above-described problem, so that the cleaning liquid does not spread evenly and only the effect is exerted on the biased portion.
かかる問題を解決するためには、ノズルの先端（噴出口）を吸入管内面などの噴出先壁面等から浮かせること（センタリング）が必要であるものの、それを簡易に実現するノズル管は存在せず、従来においては、吸入管やエアクリーナーダクトなどを取り外してセンタリングセットツールを取り付けることで、ノズルのセンタリングが行われているのみであった。しかしながら、かかるセンタリングセットツールを取り付ける方法は、分解・復元作業が必要であって時間と手間が掛かり、取り付けに際しても熟練が必要であって、普及するには至っていないのが現状である。 In order to solve such a problem, it is necessary to lift the tip (jet outlet) of the nozzle from the wall surface of the ejection destination such as the inner surface of the suction pipe (centering), but there is no nozzle pipe that can easily achieve this. Conventionally, the centering of the nozzle has only been performed by removing the suction pipe or the air cleaner duct and attaching the centering set tool. However, the method of attaching such a centering set tool requires disassembly / restoration work, takes time and effort, requires skill at the time of attachment, and has not yet spread.
そこで、本出願人は、熱可塑性を有する合成樹脂素材により製造されたノズル管本体からセンタリング機能を備える噴出ノズル管を製造すべく、ノズル管本体の長さ方向に複数の切り込みを入れてできた切片を加熱し若しくは折り返して夫々ノズル管本体の外径より外側に膨らんだ状態で冷却・固定化する工程からなる「噴出ノズル管の製造方法並びにその方法により製造される噴出ノズル管」（特許文献１）を開発し、技術提案を行っている。 Therefore, the present applicant has made a plurality of cuts in the length direction of the nozzle tube main body in order to manufacture an ejection nozzle tube having a centering function from a nozzle tube main body manufactured from a synthetic resin material having thermoplasticity. “A method for producing an ejection nozzle tube and an ejection nozzle tube produced by the method” comprising the steps of cooling or fixing a section in a state where the section is heated or folded and swelled outward from the outer diameter of the nozzle tube body (patent document) 1) has been developed and technical proposals are being made.
かかる「噴出ノズル管の製造方法並びにその方法により製造される噴出ノズル管」の技術提案は、ノズル管本体の外径より外側へ膨らんで噴出口のセンタリング位置決めを行うセンタリング機構が備えられた噴出ノズル管を提供するものであって、上記した問題の解決に充分に寄与するものとして、優れた効果があった。 The technical proposal of the “manufacturing method of the jet nozzle pipe and the jet nozzle pipe manufactured by the method” is a jet nozzle provided with a centering mechanism that swells outside the outer diameter of the nozzle pipe body and performs centering positioning of the jet outlet There is an excellent effect as a tube providing a sufficient contribution to solving the above problems.
しかしながら、該技術提案は噴出ノズル管自体にセンタリング機構を備えさせるものであるため、スプレー缶やエアゾール缶一つにつき夫々一つの噴出ノズル管が付属されている現状に鑑みると、使用済みスプレー缶・エアゾール缶と共に廃棄されてしまうこととなり、不経済であった。 However, since the technical proposal is to provide a centering mechanism for the spray nozzle tube itself, in view of the current situation that one spray nozzle tube is attached to each spray can and aerosol can, It would be uneconomical because it would be discarded along with the aerosol can.
本出願人は、上記従来の噴出ノズル管の問題点に着目し、噴出ノズル管を直接加工せずとも該噴出ノズル管の噴出口を備える先端を中空に浮かせた状態に保持できる方法はないものかとの着想のもと、噴出ノズル管を挿入可能であって当該センタリング機構を備えさせた繰り返し使用可能な補助管を開発し、本発明における「噴出ノズル管のセンタリング機能付き補助管の製造方法並びにその方法により製造される補助管」の提案に至るものである。 The present applicant pays attention to the problems of the above-mentioned conventional ejection nozzle tube, and there is no method that can keep the tip provided with the ejection port of the ejection nozzle tube in a hollow state without directly processing the ejection nozzle tube. Based on the idea of the heel, a reusable auxiliary pipe that can be inserted with an ejection nozzle pipe and provided with the centering mechanism has been developed. This leads to the proposal of an “auxiliary pipe manufactured by the method”.
本発明は、上記問題点に鑑み、繰り返し使用可能であって、且つ、噴出ノズル管の噴出口を備える先端を中空に浮かせた状態に保持可能な補助管を提供することを目的とするものである。 In view of the above problems, an object of the present invention is to provide an auxiliary pipe that can be used repeatedly and can hold a tip provided with a jet outlet of a jet nozzle pipe in a hollow state. is there.
上記目的を達成するため、本発明は、噴出ノズル管の噴出口を備える先端を中空に浮かせた状態に保持するための補助管を製造するための方法であって、所要長さを有し且つ噴出ノズル管を挿入可能な径を有して合成樹脂素材により製造されて成る補助管本体の先端から長さ方向に所定長さの切り込みを複数入れる工程と、切り込みにより補助管本体の先端部位が分割されてできた切片を夫々補助管本体の外径より外側に膨らんだ状態に折り返しつつ各切片の先端部を補助管本体の外周面に当接させた状態で接合する工程と、から構成されている。 In order to achieve the above object, the present invention is a method for manufacturing an auxiliary pipe for holding a tip provided with a jet outlet of a jet nozzle pipe in a state of floating in a hollow, having a required length and A step of making a plurality of cuts of a predetermined length in the length direction from the tip of the auxiliary tube body having a diameter into which the ejection nozzle tube can be inserted and made of a synthetic resin material, and the tip portion of the auxiliary tube body by cutting The divided sections are joined to each other while the tip of each section is brought into contact with the outer peripheral surface of the auxiliary pipe body while being folded back into a state where the sections are expanded outward from the outer diameter of the auxiliary pipe body. ing.
また、本発明は、前記補助管本体が、熱可塑性を備える合成樹脂素材により製造されて成る構成を採用し得る。 In addition, the present invention may employ a configuration in which the auxiliary pipe body is manufactured from a synthetic resin material having thermoplasticity.
さらに、本発明は、切り込みにより補助管本体の先端部位が分割されてできた切片の数が、少なくとも三以上である構成を採用し得る。 Furthermore, the present invention can employ a configuration in which the number of sections formed by dividing the tip portion of the auxiliary tube main body by cutting is at least three or more.
またさらに、本発明は、各切片の先端部をノズル管本体の外周面に当接させた状態で、該当接箇所に所定長さの熱収縮チューブを嵌合して加熱することで該熱収縮チューブを収縮させ、その後加熱された箇所を冷却して固化することで、各切片の先端部とノズル管本体の外周面とが接合されて成る構成とすることも可能である。 Still further, the present invention provides a heat shrinkable tube by fitting and heating a heat shrinkable tube of a predetermined length at the corresponding contact point in a state where the tip of each section is in contact with the outer peripheral surface of the nozzle tube body. It is also possible to have a configuration in which the tip of each section and the outer peripheral surface of the nozzle tube body are joined by shrinking the tube and then cooling and solidifying the heated portion.
そしてまた、本発明は、前記製造方法により製造される噴出ノズル管のセンタリング機能付き補助管であって、補助管本体の先端部位に、該補助管本体の外径より外側へ膨らんで挿入された噴出ノズル管の噴出口を備える先端を中空に浮かせた状態に保持するためのセンタリング機構が備えられている構成となっている。 Further, the present invention is an auxiliary pipe with a centering function of a jet nozzle pipe manufactured by the above manufacturing method, and is inserted into the distal end portion of the auxiliary pipe main body so as to swell outward from the outer diameter of the auxiliary pipe main body.

In addition, it is possible to repeatedly use one auxiliary pipe of the present invention for the spray nozzle pipe used for each spray can / aerosol can, which is excellent in cost performance. It is effective.
また、本発明にかかる噴出ノズル管のセンタリング機能付き補助管によれば、補助管本体の外径より外側へ膨らんで挿入された噴出ノズル管の噴出口を備える先端を中空に浮かせた状態に保持するためのセンタリング機構が備えられていることで、噴出ノズル管の先端が噴出先の壁面等対象物に接触することを避けることができるため、スプレー缶等の内容物をガスとの混合状態を保ちつつ噴出口から噴出先へ噴出することが可能となり、よって内容物を噴出先に満遍なく行き渡らせることが可能となる、といった優れた効果を奏するものである。 Further, according to the auxiliary pipe with the centering function of the jet nozzle pipe according to the present invention, the tip provided with the jet nozzle nozzle outlet bulged outward from the outer diameter of the auxiliary pipe main body is held in a state of being floated in the air Since the centering mechanism is provided to prevent the tip of the ejection nozzle tube from coming into contact with the target object such as the wall surface of the ejection destination, the contents of the spray can etc. are mixed with the gas. It is possible to eject from the ejection port to the ejection destination while keeping it, and thus it is possible to achieve an excellent effect that the contents can be spread evenly over the ejection destination.
本発明は、補助管本体１０の先端部位１３に、該補助管本体１０の外径より外側へ膨らんで挿入された噴出ノズル管４０の噴出口４１を備える先端を中空に浮かせた状態に保持するためのセンタリング機構３０が備えられていることを最大の特徴とする。
以下、本発明にかかる噴出ノズル管４０のセンタリング機能付き補助管１の製造方法並びにその方法により製造される補助管１の実施形態を、図面に基づき説明する。
In the present invention, the tip of the auxiliary pipe body 10 having the jet nozzle 41 of the jet nozzle pipe 40 swelled and inserted outside the outer diameter of the auxiliary pipe main body 10 is held in a hollow state at the tip portion 13 of the auxiliary pipe main body 10. The centering mechanism 30 is provided with a maximum feature.
Hereinafter, an embodiment of the auxiliary pipe 1 with the centering function of the jet nozzle pipe 40 according to the present invention and the auxiliary pipe 1 manufactured by the method will be described with reference to the drawings.
なお、本発明は、下記の実施形態に示した構成に特に限定されるものではなく、本発明の技術的思想の要旨に逸脱しない範囲で任意に変更することができるものである。 The present invention is not particularly limited to the configurations shown in the following embodiments, and can be arbitrarily changed without departing from the gist of the technical idea of the present invention.
図１は、本発明にかかる噴出ノズル管４０のセンタリング機能付き補助管１の製造方法の実施形態を示すフロー図である。
すなわち本発明は、補助管本体１０を以下の工程で順次加工することにより、噴出ノズル管４０のセンタリング機能付き補助管１を製造するものである。
なお、本実施例で使用する補助管本体１０は、所要長さを有し且つ噴出ノズル管４０を挿入可能な径を有して、熱可塑性を有する合成樹脂素材、例えばＬＤＰＥ（低密度ポリエチレン）等により製造されている。
FIG. 1 is a flowchart showing an embodiment of a method for manufacturing the auxiliary pipe 1 with a centering function of the ejection nozzle pipe 40 according to the present invention.
That is, the present invention manufactures the auxiliary pipe 1 with the centering function of the ejection nozzle pipe 40 by sequentially processing the auxiliary pipe main body 10 in the following steps.
The auxiliary pipe body 10 used in this embodiment has a required length and a diameter into which the ejection nozzle pipe 40 can be inserted, and is a synthetic resin material having thermoplasticity, such as LDPE (low density polyethylene). Etc. are manufactured.
まず初めに、補助管本体１０に挿入路１５まで貫通する切り込み３１を入れる。切り込み３１を入れる位置については、補助管本体１０おける先端部位１３であり、補助管本体１０の先端１４から所定長さだけ切り込み３１が入れられる。すなわち、切り込み３１を入れる方向は、補助管本体１０の長さ方向となる。
このとき、入れられる切り込み３１の長さについては、特に限定はなく、該切り込み３１によりできる切片３２を補助管本体１０の外径より外側へどの程度膨らませるか、すなわち、噴出ノズル管４０の噴出口４１と噴出先壁面等対象物との距離などを考慮して、任意に決定される。
First, a cut 31 that penetrates to the insertion path 15 is made in the auxiliary pipe body 10. The position where the cut 31 is made is the tip portion 13 in the auxiliary pipe body 10, and the cut 31 is made by a predetermined length from the tip 14 of the auxiliary pipe body 10. That is, the direction in which the cut 31 is made is the length direction of the auxiliary pipe body 10.
At this time, the length of the cut 31 to be inserted is not particularly limited, and how much the section 32 formed by the cut 31 is inflated outward from the outer diameter of the auxiliary pipe main body 10, that is, the ejection of the ejection nozzle tube 40. The distance is arbitrarily determined in consideration of the distance between the outlet 41 and the target object such as the wall surface of the ejection destination.
切り込み３１は、一の補助管本体１０に対し複数入れられることとなる。該切り込み３１の数については、複数であれば特に限定するものではないが、挿入された噴出ノズル管４０が噴出先のどの方向位置にあってもセンタリング機能を果たせるよう、少なくとも三以上の切り込み３１を入れることが望ましく、これにより三以上の切片３２が設けられることとなる
なお、かかる複数の切り込み３１は、補助管本体１０外周に対し均等間隔で入れられることが望ましい。これにより、設けられる切片３２の幅は夫々均等となる。
A plurality of the cuts 31 are made with respect to one auxiliary pipe body 10. The number of the cuts 31 is not particularly limited as long as it is plural, but at least three or more cuts 31 are provided so that the inserted jet nozzle tube 40 can perform the centering function regardless of the position of the jet nozzle. Thus, three or more pieces 32 are provided, and it is desirable that the plurality of cuts 31 are made at equal intervals with respect to the outer periphery of the auxiliary pipe body 10. Thereby, the width | variety of the division | segmentation 32 provided becomes equal respectively.
次に、上記切り込み３１により補助管本体１０の先端部位が分割されてできた切片３２を、夫々補助管本体１０の外径より外側に膨らんだ状態に折り返す。折り返す際には、夫々の先端部３３が補助管本体１０の外周面に当接する状態まで折り返す。そして、該先端部３３が補助管本体１０の外周面に当接された状態において、両者は接合されることとなる。 Next, the sections 32 formed by dividing the tip portion of the auxiliary tube main body 10 by the cuts 31 are folded back to a state in which they swell outward from the outer diameter of the auxiliary tube main body 10. When folding back, each tip 33 is folded back until it comes into contact with the outer peripheral surface of the auxiliary pipe body 10. In a state where the distal end portion 33 is in contact with the outer peripheral surface of the auxiliary pipe main body 10, both are joined.
切片３２の先端部３３と補助管本体１０の外周面との接合方法については、特に限定するものではないが、例えば接着剤による接着や融着、溶着、粘着テープ等による巻着などが考え得る。
このとき、かかる接合方法について、熱収縮チューブ１２による接合態様が考え得る。
The method for joining the distal end portion 33 of the section 32 and the outer peripheral surface of the auxiliary tube main body 10 is not particularly limited. For example, adhesion or fusion with an adhesive, welding, winding with an adhesive tape, or the like can be considered. .
At this time, the joining mode by the heat-shrinkable tube 12 can be considered about this joining method.
かかる熱収縮チューブ１２による接合方法を採用した場合の接合態様は、以下の通りとなる。すなわち、補助管本体１０の外周面に当接された先端部３３の全てが覆い被されるように、該当接箇所に所定長さの熱収縮チューブ１２を嵌合する。このとき、嵌合すべき熱収縮チューブ１２の長さについて、切片３２の先端３３が補助管本体１０の外周面に当接された状態で固定可能であれば、特に限定するものではない。 A joining mode when the joining method using the heat shrinkable tube 12 is adopted is as follows. That is, the heat-shrinkable tube 12 having a predetermined length is fitted to the corresponding contact portion so that the entire distal end portion 33 in contact with the outer peripheral surface of the auxiliary tube main body 10 is covered. At this time, the length of the heat-shrinkable tube 12 to be fitted is not particularly limited as long as it can be fixed in a state where the tip 33 of the section 32 is in contact with the outer peripheral surface of the auxiliary pipe body 10.
次いで、かかる熱収縮チューブ１２が嵌合された箇所を加熱する。加熱方法については特に限定はなく、また、熱収縮チューブ１２の加熱温度については、該熱収縮チューブ１２の収縮温度を考慮して、適宜決定される。熱収縮チューブ１２は、加熱されると収縮する作用を有しているため、加熱により径が小さくなる。この作用を利用して、熱収縮チューブ１２が切片３２の先端３３に覆い被さった状態で加熱により収縮されることで、該先端３３は熱収縮チューブ１２により保持されることとなる。 Next, the portion where the heat shrinkable tube 12 is fitted is heated. The heating method is not particularly limited, and the heating temperature of the heat shrinkable tube 12 is appropriately determined in consideration of the shrinkage temperature of the heat shrinkable tube 12. Since the heat-shrinkable tube 12 has a function of contracting when heated, the diameter is reduced by heating. By utilizing this action, the heat shrinkable tube 12 is contracted by heating in a state of covering the tip 33 of the section 32, so that the tip 33 is held by the heat shrinkable tube 12.
なお、加熱による熱収縮チューブ１２の収縮程度については、特に限定はないが、例えば、熱収縮チューブ１２の外径が補助管本体１０の外径に一致する程度に収縮させる態様が考え得る。
また、熱収縮チューブ１２の加熱の際、補助管本体１０も同時に軟化することで挿入路１５が閉鎖されてしまわないよう、補助管本体１０の挿入路１５内に所定径幅を有する針材を差込み配置することが望ましい。かかる針材の径幅については特に限定はない。なお、針材を差し込んだ場合に、該針材を冷却することで、必要に応じて加熱による補助管本体１０の軟化を防止する態様も考え得る。かかる針材の冷却方法としては、例えば該針材としてパイプ状のものを用いて、その中空内に冷却水などの冷却剤を通す態様などが考え得る。
The degree of contraction of the heat-shrinkable tube 12 due to heating is not particularly limited, but, for example, a mode in which the outer diameter of the heat-shrinkable tube 12 is contracted to the extent that the outer diameter of the auxiliary pipe body 10 coincides can be considered.
Further, when heating the heat shrinkable tube 12, a needle material having a predetermined diameter width is inserted into the insertion path 15 of the auxiliary pipe body 10 so that the insertion path 15 is not closed by simultaneously softening the auxiliary pipe body 10. It is desirable to place it in an inset. There is no particular limitation on the diameter width of the needle material. In addition, when a needle material is inserted, the aspect which prevents softening of the auxiliary pipe main body 10 by heating as needed can be considered by cooling this needle material. As a method for cooling the needle material, for example, a pipe-shaped material may be used as the needle material, and a coolant such as cooling water may be passed through the hollow.
その後、加熱された箇所を冷却する。冷却する方法は、自然冷却と強制冷却とを問わず、任意である。冷却することにより、熱収縮チューブ１２は、補助管本体１０を外周側から押し込んで締め付けた状態で固化されるとともに、切片３２の先端３３を補助管本体１０の外周面に当接された状態で保持しつつ固定することとなり、その結果として切片３２は、補助管本体１０の外径より外側へ膨らんだ状態となる。 Then, the heated location is cooled. The cooling method is arbitrary regardless of natural cooling or forced cooling. By cooling, the heat shrinkable tube 12 is solidified in a state where the auxiliary tube body 10 is pushed from the outer peripheral side and tightened, and the tip 33 of the section 32 is in contact with the outer peripheral surface of the auxiliary tube main body 10. As a result, the section 32 swells outward from the outer diameter of the auxiliary pipe body 10.
以上の工程を経ることにより、本発明にかかる噴出ノズル管４０のセンタリング機能付き補助管１が完成する。本発明にかかる製造方法により製造された補助管１によれば、補助管本体１０の先端部位１３において、切り込み３１によりできた切片３２の先端３３がノズル管本体１０の外周面に当接された状態で接合されることで、該切片３２が補助管本体１０の外径より外側へ膨らんだ状態となっている。これにより、その膨らんだ部分が挿入された噴出ノズル管４０の噴出口４１を備える先端を中空に浮かせた状態に保持すべく作用し、全体として噴出ノズル管４０のセンタリング機構３０を備えた補助管１となる。 By passing through the above process, the auxiliary pipe | tube 1 with the centering function of the ejection nozzle pipe | tube 40 concerning this invention is completed. According to the auxiliary tube 1 manufactured by the manufacturing method according to the present invention, the distal end 33 of the section 32 formed by the cut 31 is brought into contact with the outer peripheral surface of the nozzle tube main body 10 at the distal end portion 13 of the auxiliary tube main body 10. By joining in the state, the section 32 is inflated outward from the outer diameter of the auxiliary pipe body 10. Thereby, the auxiliary pipe provided with the centering mechanism 30 of the ejection nozzle pipe 40 as a whole acts to hold the tip of the ejection nozzle pipe 40 having the bulged portion inserted therein in a state of floating in the air. 1

When the auxiliary tube 1 according to the present invention is inserted into the ejection destination, the section 32 bulging outward is inserted while being pushed inward. At this time, since the segment 32 is folded in a curved shape, it can be smoothly inserted without resistance without interfering with the insertion. When the distal end portion 13 of the auxiliary tube 1 arrives at the target location, the section 32 is released and bulges outward to function as the centering mechanism 30.
While maintaining this state, the ejection nozzle tube 40 is inserted into the insertion path 15 from the other end of the auxiliary tube 1, and the distal end of the ejection nozzle tube 40 is finally provided at the distal end portion of the auxiliary tube 10. 13 is projected. Thereby, the tip provided with the jet nozzle 41 of the jet nozzle pipe 40 is held in a state of floating in the air by the centering mechanism 30 of the auxiliary pipe 1.
なお、本発明にかかる補助管１を噴出先から取り出す場合については、上記挿入する場合の逆を行えばよい。すなわち、噴出ノズル管４０を引き抜き、次いで補助管１を噴出先から引き抜けばよい。 In addition, what is necessary is just to perform the reverse case of the said insertion about the case where the auxiliary tube 1 concerning this invention is taken out from an ejection destination. That is, the ejection nozzle tube 40 is pulled out, and then the auxiliary tube 1 is pulled out from the ejection destination.
図３は、本発明にかかる噴出ノズル管４０のセンタリング機能付き補助管１の他の使用態様を示す説明図である。すなわち、該補助管１の使用態様は、以下の通りである。
本発明にかかる補助管１を噴出先に挿入する場合、外側へ膨らんだ切片３２が挿入の邪魔にならないよう、補助管本体１０の外径よりひと回り大きいガイド管５０を用意し、補助管１の先端部位に装着する。これにより、切片３２はガイド管５０内に収まって、それ以上外側へ膨らんだ状態とはならない。該ガイド管５０が装着された状態のまま補助管１を噴出先に挿入し、その先端部位１３が目的箇所に到着した段階で、補助管１についてはその位置を保ちつつ、ガイド管５０を手前側に引き下げるようにスライドさせる。すると補助管１の先端部位１３がガイド管５０からむき出しとなり、該ガイド管５０内に収まっていた切片３２が解放されて外側へ膨らんだ状態となって、センタリング機構３０として機能する。
かかる状態を維持しつつ、補助管１の他端から挿入路１５内へ噴出ノズル管４０を挿入し、最終的に噴出ノズル管４０の噴出口４１が備えられた先端を補助管１０の先端部位１３から突出させる。これにより、噴出ノズル管４０の噴出口４１を備える先端が、補助管１のセンタリング機構３０によって中空に浮いた状態で保持されることとなる。
FIG. 3 is an explanatory view showing another usage mode of the auxiliary pipe 1 with a centering function of the ejection nozzle pipe 40 according to the present invention. That is, the usage mode of the auxiliary pipe 1 is as follows.

Attach to the tip. As a result, the section 32 does not fit into the guide tube 50 and does not swell further outward. With the guide tube 50 mounted, the auxiliary tube 1 is inserted into the ejection destination, and when the distal end portion 13 arrives at the target location, the guide tube 50 is moved forward while maintaining the position of the auxiliary tube 1. Slide it down to the side. Then, the distal end portion 13 of the auxiliary tube 1 is exposed from the guide tube 50, and the section 32 stored in the guide tube 50 is released and swells outward to function as the centering mechanism 30.
While maintaining this state, the ejection nozzle tube 40 is inserted into the insertion path 15 from the other end of the auxiliary tube 1, and the distal end of the ejection nozzle tube 40 is finally provided at the distal end portion of the auxiliary tube 10. 13 is projected. Thereby, the tip provided with the jet nozzle 41 of the jet nozzle pipe 40 is held in a state of floating in the air by the centering mechanism 30 of the auxiliary pipe 1.
なお、本発明にかかる補助管１を噴出先から取り出す場合については、上記挿入する場合の逆を行えばよい。すなわち、噴出ノズル管４０を引き抜き、次いでガイド管５０を補助管１の先端部位１３側へスライドさせ、その状態のまま噴出先から引き抜けばよい。 In addition, what is necessary is just to perform the reverse case of the said insertion about the case where the auxiliary tube 1 concerning this invention is taken out from an ejection destination. That is, the ejection nozzle tube 40 is pulled out, and then the guide tube 50 is slid toward the distal end portion 13 side of the auxiliary tube 1 and pulled out from the ejection destination in that state.
以上の通り、本発明にかかる噴出ノズル管４０のセンタリング機能付き補助管１は、外側へ膨らんだ切片３２が噴出先の壁面等対象物に接触することで、逆にノズル管本体４０の先端が該壁面等対象物に接触することを避けることができ、これによりノズル管本体４０の噴出口４１を噴出先の中空に浮かせた状態に保持することが可能となる。これにより、スプレー缶等の内容物をガスとの混合状態を保ちつつ噴出口４１から噴出先へ噴出することが可能となり、よって内容物を噴出先に満遍なく行き渡らせることが可能となる。 As described above, the auxiliary tube 1 with the centering function of the ejection nozzle tube 40 according to the present invention has the tip 32 of the nozzle tube body 40 conversely when the section 32 bulging outward contacts an object such as the wall surface of the ejection destination. It is possible to avoid contact with an object such as the wall surface, and thus it is possible to hold the ejection port 41 of the nozzle tube main body 40 in a state of floating in the hollow of the ejection destination. As a result, the contents such as the spray can can be ejected from the ejection port 41 to the ejection destination while maintaining the mixed state with the gas, and thus the contents can be evenly distributed to the ejection destination.
本発明は、簡易な製造方法により、優れた効果を奏する噴出ノズル管４０のセンタリング機能付き補助管１を提供するものであり、その製造された補助管１によれば、繰り返し使用できると共に安定かつ一定の噴出を実現可能であって、本発明の産業上の利用可能性は非常に高いものと思料する。 The present invention provides the auxiliary pipe 1 with the centering function of the ejection nozzle pipe 40 having an excellent effect by a simple manufacturing method. According to the manufactured auxiliary pipe 1, the auxiliary pipe 1 can be used repeatedly and stably. It is possible to realize a certain eruption, and it is considered that the industrial applicability of the present invention is very high.
