Description

【０００１】
【発明の属する技術分野】
本発明は、着脱を容易にした安全ピンに関するものである。
【０００２】
【従来の技術】
従来、例えば洋服に記章、名札、ブローチ等を付けたり、洋服、カバーなどの仮止めなどをする等の用途で使用される安全ピンとしては、一端に針先部を備え他端側に基部を備えてこれら針先部と基部との間をコイル状に巻いてバネ部を形成し前記針先部と基部とが常時開くように構成されているピンと、このピンの基部に固定され前記針先部を収容して掛止する溝状の収容部を備えたピン受とを備えてなり、前記針先部と基部側へと摘んで前記針先部が基部側へ近づく方向へピンを弾性変形させることによって針先部をピン受の収容部に収容するように構成されているものが知られている。
【０００３】
【発明が解決しようとする課題】
ところが、このように細いピンを弾性変形させ、さらにその状態を保ってピン受の収容部に対応する位置まで針先部を移動させるためにはある程度の力を要し、力の弱い女性や子供、老人等にとってその動作が難しいという不具合があった。また、針先部を収容部に掛止させるためには、前記針先部を基部側へ接近させる動作、収容部に対して挿入する動作、適正な位置で把持した手を外す動作の３アクション必要なため時間を要す点、さらにこのように細いピンを弾性変形させつつピン受に形成された収容部に対して適正に位置付けねばならない点においても安全ピンの装着を煩雑で困難ものとしていた。
【０００４】
そこで、このような不具合を解決すべく、ビンではなくピン受の方を操作することによって、大きな力を要せず簡単に装着対象物に装着することが可能な使用勝手の良好な安全ピンを提供する。
【０００５】
【課題を解決するための手段】
すなわち、本発明は、一端側に針先部を備えるとともに他端側に基部を備え前記針先部と基部とが並行するように形成したピンと、前記基部に回転可能に取り付けられ、開口を有しこの開口を通じて前記針先部を収容する収容部とこの収容部内における針先部を挿脱可能に掛止して抜け止めとして機能する掛止部とを備えて前記基部に回転可能に取り付けられるピン受とを具備してなり、ピン受を所定の退避位置からピンの基部の軸心周りに回転させ、針先部が掛止部を乗り越えて前記収容部内に収容されるようにしている安全ピンである。なお、「針先部と基部とが並行する」とは、針先部と基部とが平行をなしているものに限らず先端部に向かって漸次広がるように或いは漸次狭まるように並んでいるようなものであってもよい。また、針先部及び基部は、直線をなすように延びるものには限られない。
【０００６】
このようなものであれば、従来のようにピン側を手で摘んで弾性変形させることでピン受に収容するのでなく、ピン受側を回転させるという動作だけで、針先を収容部に収容することができるようになり、加えて従来のように針先部の細かい位置調整を行わずともよいようになる。すなわち、ピン受を回転させるというワンアクションで、しかも大きな操作力を要せずに簡単に布地等の装着対象物に装着することができるようになり、力の弱い女性、子供や老人等に使い易い安全ピンを提供することが可能となる。
【０００７】
また、収容部は、ピン受の側縁部近傍に位置するように設けることが望ましい。ピン受の収容部よりも外側の側縁部分の厚み幅寸法が薄くなり、ピンの挿入時にその側縁部分を弾性変形させ外方空間に逃がすようにしてスムーズに掛止部を乗り越えて収容部に収容させることが可能となるからである。そして、このように収容部を側縁部近傍に形成した場合には、掛止部を、前記収容部の開口幅をピン受の側縁部側から内側へ向かって狭めるようなものに構成し、当該掛止部を針先部が乗り越える際に、前記側縁部分を外方空間へ移動させつつ、収容部内へ収容させるようにすることが望ましい。
【０００８】
また、収容部の簡素で好ましい具体的態様としては、前記針先部の軸方向に沿った溝状に形成したものが挙げられる。
【０００９】
針先部の収容部内へのスムーズな挿入を助長するには、掛止部に、針先を収容部内へ誘導するテーパ面を形成することが望ましい。そして、このようなテーパ面を備えていて簡便なものとしては、略部分球状をなす突起が挙げられる。
【００１０】
また、針先部の刺し込み時にピン受が干渉しないようにするためには、退避位置を収容位置とほぼ背向する位置、すなわち基部を中心に収容位置とほぼ１８０度反対側に位置する退避位置との間で回転可能となるようにすると望ましい。
【００１１】
さらに、使用勝手を良好なものとするためには、前記針の基部と針先部との間に、針先部に刺し込んだ布地など装着対象物の移動を規制する規制部材を取り付けるようにすると好ましい。そして、このような規制部材の望ましい一例として、前記針先部と基部との境界部分に取り付けた球体であるようなものが挙げられる。このようなものであれば、規制部材としての機能の他、簡素な構成でデザイン性を向上させることも可能であり、さらにこの安全ピンを持ち易くなるなどの効果も奏する。
【００１２】
【発明の実施の形態】
以下、本発明の一実施形態を、図面を参照して説明する。
【００１３】
図１から図５に示した本実施の形態の安全ピンＡは、ピン１とこのピン１に取り付けられたピン受２とをその主たる構成としたものである。
【００１４】
ピン１は、一端側に針先部１１を備えるとともに他端側に基部１２を備え前記針先部１１と基部１２とが並行するように形成したものである。具体的には、金属等を素材とした線材を湾曲させて、針先部１１と基部１２とを略平行をなすように形成し、平面視Ｕ字型に成形したものである。針先部１１は、その先端部分を、布地などに刺し込み可能に尖らせてある。また、針先部１１と基部１２との間の湾曲部位には、針先部１１に刺し込んだ布地等の装着対象物の移動を規制する規制部材たる球体３を貫通させ移動不能に取り付けている。
【００１５】
ピン受２は、前記針先部１１を収容する収容部たる収容溝２１と、この収容溝２１内における針先部１１を挿脱可能に掛止し得る掛止部たる突起２２とを備えてなり、前記基部１２に回転可能に取り付けられたものである。収容溝２１は、開口２１ａを有しこの開口２１ａを通じて当該ピン受２の側縁部近傍に針先部の１１軸方向に沿って形成され、その開口幅は、針先部１１よりも所定寸法大きく設定されている。突起２２は、収容溝２１を構成する軸方向に沿った対向する２つの壁面２１ｂ、２１ｃのうち、側縁部側（外側）に位置する壁面２１ｂから軸方向に直交するように突出させたものである。そして、この突起２２によって収容溝２１の開口幅が側縁部側から内側へ向かって狭まり、その最狭幅寸法が針先部１１の軸の幅寸法よりも小さくなるようにしている。また、この突起２２は、本実施形態では略半球状をなしその外表面２２ａを針先部１１を収容溝２１内へ誘導するとともに脱抜時に開口２１ａ側へ誘導するテーパ面として機能させている。また、このピン受２は半割成形によるもので、それぞれの半割体２ａ、２ｂに凹部２３ａ、２３ｂ（図５参照）を形成して半割体２ａ、２ｂを合着した場合にこれら凹部２３ａ、２３ｂによって、前記基部１２の基端部分に設けられた取付部１２１よりその径が大きく取付部１２１を回転可能に保持する保持部２３を構成している。そして、このピン受２は、図２及び図４に示したように、前記収容溝２１に前記針先部１１が収容される収容位置（ｐ）と、この収容位置（ｐ）と背向する、すなわち前記収容位置（ｐ）と１８０度反対側に位置する退避位置（ｑ）との間で回転できるようになっている。なお、ピン受２を基部１２に対して回転可能に取り付けるのは、他の機構によるものでも構わない。
【００１６】
しかして、この安全ピンＡを、例えば装着対象物である洋服の生地等に装着する場合には、ピン受２を前記退避位置（ｑ）に位置付けた状態として、針先部１１を刺し込む。次に、手でピン１を動かないように固定しておいて、ピン受２を針先部１１側へ回転させると、図５に示したように針先部１１が収容溝２１内に収容される。すなわち、収容溝２１を針先部１１と対向させるように位置させた状態とし（ａ）、ピン受２を針先部１１に対して若干押すようにすれば、針先部１１が、突起２２のテーパ状の外表面２２ａに当接し突起２２及び壁面２１ｂより外方に位置する側縁部分２４を外方空間に押すようにして乗り越え（ｂ）、当該ピン受２は収容位置（ｐ）に位置付けられることとなる（ｃ）。この際、針先部１１を基部１２側へ若干寄せるようにした状態でピン受２を回転させて、針先部１１の収容溝２１内へ挿入動作がよりスムーズになるようにしてもよい。一方、安全ピンＡを外す場合には、ピン受２を回転させて針先部１１を、突起２２を乗り越えて収容溝から脱抜させるようにする。この際、針先部１１は、突起２２の外表面２２ａに誘導されて収容溝２１の開口２１ａ側へ移動する。
【００１７】
以上のように本実施形態における安全ピンＡは、ピン受２側を回転させて針先部１１を収容溝２１内へ収容するようにしているので、従来の安全ピンのようにピン部分を弾性変形させるような大きな力を要せず、しかも回転動作のみで装着することができる。すなわち、力の弱い女性、子供、老人などにも使用し易いものとすることができる。さらに、細い針先部１１の位置調整を行なわずともよいため、手元が見難いような場合であっても装着が簡単である。
【００１８】
また、収容溝２１をピン受２の側縁部近傍に形成したので、壁面２１ｂより側縁部分２４の厚み寸法が薄くなり、針先部１１を挿入させる場合に壁面２１ｂに形成した突起２２とともに弾性変形させて外方空間へ移動させ易く、挿入がスムーズに行なえる。ピン受の側縁部側から内側へ向かって狭めるように形成されている。
【００１９】
突起２２を、略半球状に形成したので、テーパ面として機能する外周面２２ａによ誘導されて針先部１１の収容溝内への挿入がスムーズに行なえ、さらに脱抜もスムーズに行なえる。
【００２０】
ピン受２を、収容位置（ｐ）と背向する退避位置（ｑ）まで回転可能なものとしたので、ピン受２が装着対象物に装着する際に針先部１１の刺し込みの邪魔にならない。
【００２１】
また、針先部１１と基部１２との境界部位（中間位置）に、規制部材たる球体３を取り付けたので、装着状態において装着対象物がずれない。また、この球体３にピン受２と同色或いは異なる色に着色するなどして、デザイン性を向上させることが可能となる。また、安全ピンＡを持ち上げる際などにも掴み易い。なお、この規制部材としては、球状以外の形状であってもよい。
【００２２】
本発明は、上記実施形態に限らない。
【００２３】
例えば、図６から図８に示したような安全ピンＢ、Ｃ、Ｄであってもよい。なお、図中、上記実施形態と同様の機能、構成のものには、同じ符号の先頭にそれぞれ「Ｂ」、「Ｃ」、［Ｄ」を付している。
【００２４】
まず、図６にその平面図を示したように、収容溝Ｂ２１を構成する両壁面Ｂ２１ｂ、Ｂ２１ｃから突出する掛止部たる突起Ｂ２２、Ｂ２２’を設けた安全ピンＢであってもよい。
【００２５】
そして、図７にその平面図を示したように、前記突起Ｂ２２’と同様の突起Ｃ２２’を突出させる壁面Ｃ２１ｃの近傍に切欠Ｃ２５を形成することによって、収容溝Ｃ２１を構成する壁面Ｃ２１ｃを形成する壁部Ｃ２６の厚み幅寸法を薄くなるようにした安全ピンＣであってもよい。このようなものであれば、針先部Ｃ１１を挿入するときこれら突起Ｃ２２、Ｃ２２’を乗り越える際に、側縁部分Ｃ２４及び壁部Ｃ２６がそれぞれ外方空間及び切欠Ｃ２５内へ逃げるように移動し、開口幅が広がってスムーズに挿入できる。
【００２６】
さらに、図８にその縦断面図を示したような安全ピンＤであってもよい。この安全ピンＤは、ピン受Ｄ２に、開口Ｄ２１ａを形成するとともにその側縁部分を湾曲した形状に成形して、開口端近傍に位置する壁部を掛止部Ｄ２２として機能させこの掛止部Ｄ２２に連続する奥方部分を針先部Ｄ１１を収容する収容部Ｄ２１として機能させるようにしたものである。そして、この掛止部Ｄ２２の開口端側に針先部Ｄ１１を収容部Ｄ２１内へ誘導するテーパ面Ｄ２２ａを形成してある。このようなものであれば、ピン受Ｄ２をピンＤ１の基部Ｄ１２の軸心周りに回転させて、針先部Ｄ１１を収容部Ｄ２１と対向するように位置付けるようにすれば、（ａ）針先部Ｄ１１が前記テーパ面Ｄ２２ａに沿って基部Ｄ１１側へ移動し（ｂ）、思案点（最も内側に位置するポイント）を超えるとそのまま収容部Ｄ２１内へスムーズに移動する（ｃ）。
【００２７】
なお、上記実施形態何れにおいても、ピン受の形状は、図示例のものに限らない。また、針先部と基部との境界部分を屈曲させてピンを形成したものであってもよい。
【００２８】
その他、各部の具体的構成についても上記実施形態に限られるものではなく、本発明の趣旨を逸脱しない範囲で種々変形が可能である。
【００２９】

すなわち、本発明の安全ピンは、従来のようにピン側を手で摘んで弾性変形させることでピン受に収容するのでなく、ピン受側を回転させるという動作だけで、針先を収容部に収容することができ、加えて従来のように針先部の細かい位置調整を行わずともよい。すなわち、ピン受を回転させるというワンアクションで、しかも大きな操作力を要せずに簡単に布地等の装着対象物に装着することができ、力の弱い女性、子供や老人等に使い易い安全ピンを提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a safety pin that can be easily attached and detached.
[0002]
[Prior art]
Conventionally, as a safety pin used in applications such as attaching insignia, name tags, brooches, etc. to clothes, temporarily attaching clothes, covers, etc., a needle tip is provided at one end and a base is provided at the other end. A pin that is wound between the needle tip portion and the base portion in a coil shape to form a spring portion so that the needle tip portion and the base portion are always open, and the needle tip fixed to the base portion of the pin A pin holder provided with a groove-shaped accommodation portion that accommodates and latches the portion, and the pin is elastically deformed so that the needle tip portion approaches the base side by pinching the needle tip portion and the base side. What is comprised so that a needle | hook tip part may be accommodated in the accommodating part of a pin holder by making it do is known.
[0003]
[Problems to be solved by the invention]
However, it takes a certain amount of force to elastically deform such a thin pin, and move the needle tip to a position corresponding to the pin receiving portion while maintaining this state. There was a problem that the operation was difficult for elderly people. In addition, in order to hook the needle tip portion on the housing portion, there are three actions: an operation of bringing the needle tip portion closer to the base side, an operation of inserting the needle tip portion into the housing portion, and an operation of removing the hand gripped at an appropriate position. It is complicated and difficult to mount the safety pin in that it takes time because it is necessary, and it must be properly positioned with respect to the accommodating portion formed in the pin holder while elastically deforming such a thin pin. .
[0004]
Therefore, in order to solve such problems, by operating the pin holder instead of the bin, a safe pin with good usability that can be easily mounted on the mounting object without requiring a large force is required. provide.
[0005]
[Means for Solving the Problems]
That is, the present invention includes a pin provided with a needle tip portion at one end side and a base portion at the other end side so that the needle tip portion and the base portion are parallel to each other, and is rotatably attached to the base portion and has an opening. A holding portion that accommodates the needle tip portion through the opening and a hook portion that detachably hooks the needle tip portion in the housing portion and functions as a retaining member and is rotatably attached to the base portion. The pin holder is provided, and the pin holder is rotated around the axial center of the base of the pin from a predetermined retracted position, so that the needle tip portion passes over the latching portion and is accommodated in the accommodating portion. It is a pin. “The needle tip portion and the base portion are parallel to each other” is not limited to the case where the needle tip portion and the base portion are parallel to each other, and the needle tip portion and the base portion are arranged so as to gradually widen or gradually narrow toward the distal end portion. It may be anything. Further, the needle tip part and the base part are not limited to those extending so as to form a straight line.
[0006]
If this is the case, the needle tip is accommodated in the accommodating portion only by the operation of rotating the pin receiving side, instead of accommodating the pin side by elastically deforming by pinching the pin side by hand as in the prior art. In addition, it is not necessary to finely adjust the position of the needle tip portion as in the prior art. In other words, it can be easily attached to an object to be worn, such as cloth, with a single action of rotating the pin holder and without requiring a large operating force, and can be used for weak women, children, elderly people, etc. An easy-to-use safety pin can be provided.
[0007]
Moreover, it is desirable to provide the accommodating portion so as to be located in the vicinity of the side edge portion of the pin receiver. The thickness width dimension of the side edge part outside the pin holder's receiving part becomes thinner, and when inserting the pin, the side edge part is elastically deformed to escape to the outer space and smoothly get over the latching part. This is because it is possible to accommodate them. And when the accommodating part is formed in the vicinity of the side edge part in this way, the latching part is configured to narrow the opening width of the accommodating part from the side edge side of the pin receiver toward the inside. When the needle tip part gets over the hook part, it is desirable to accommodate the side edge part in the accommodating part while moving the side edge part to the outer space.
[0008]
Moreover, what was formed in the groove shape along the axial direction of the said needle tip part as a simple and preferable specific aspect of an accommodating part is mentioned.
[0009]
In order to facilitate smooth insertion of the needle tip portion into the housing portion, it is desirable to form a tapered surface on the latching portion that guides the needle tip into the housing portion. And as a simple thing provided with such a taper surface, the processus | protrusion which makes a substantially partial spherical shape is mentioned.
[0010]
Further, in order to prevent the pin holder from interfering when the needle tip portion is inserted, the retracted position is substantially opposite to the retracted position, that is, the retracted position located approximately 180 degrees opposite to the retracted position with the base as the center. It is desirable to be able to rotate between positions.
[0011]
Furthermore, in order to improve usability, a regulating member that regulates the movement of an object to be mounted such as a cloth inserted into the needle tip portion is attached between the base portion of the needle and the needle tip portion. It is preferable. A desirable example of such a restricting member is a sphere attached to a boundary portion between the needle tip portion and the base portion. If it is such, in addition to the function as a restricting member, it is possible to improve the design with a simple configuration, and there are also the effects that it is easier to hold the safety pin.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0013]
The safety pin A of the present embodiment shown in FIGS. 1 to 5 has a pin 1 and a pin receiver 2 attached to the pin 1 as its main configuration.
[0014]
The pin 1 has a needle tip portion 11 on one end side and a base portion 12 on the other end side, and is formed so that the needle tip portion 11 and the base portion 12 are parallel to each other. Specifically, a wire rod made of metal or the like is curved so that the needle tip portion 11 and the base portion 12 are formed substantially parallel to each other and formed into a U-shape in plan view. The tip of the needle tip 11 is sharpened so that it can be inserted into a cloth or the like. In addition, a spherical body 3 that is a regulating member that regulates the movement of a wearing object such as a cloth stabbed into the needle tip portion 11 is passed through the curved portion between the needle tip portion 11 and the base portion 12 so as to be immovable. Yes.
[0015]
The pin receiver 2 includes an accommodation groove 21 that is an accommodation portion that accommodates the needle tip portion 11, and a protrusion 22 that is an engagement portion that can detachably attach the needle tip portion 11 in the accommodation groove 21. And is rotatably attached to the base 12. The housing groove 21 has an opening 21 a and is formed along the 11 axis direction of the needle tip portion in the vicinity of the side edge portion of the pin receiver 2 through the opening 21 a, and the opening width is a predetermined dimension than the needle tip portion 11. It is set large. The protrusion 22 protrudes so as to be orthogonal to the axial direction from the wall surface 21b located on the side edge (outside) of the two opposing wall surfaces 21b and 21c along the axial direction constituting the housing groove 21. It is. The projection 22 narrows the opening width of the receiving groove 21 from the side edge to the inside, and the narrowest width is made smaller than the width of the shaft of the needle tip 11. In addition, the protrusion 22 has a substantially hemispherical shape in the present embodiment, and the outer surface 22a functions as a tapered surface that guides the needle tip portion 11 into the receiving groove 21 and guides the needle tip portion 11 toward the opening 21a. . The pin holder 2 is formed by half molding. When the concave portions 23a and 23b (see FIG. 5) are formed in the respective half halves 2a and 2b, and the half halves 2a and 2b are joined, these concave portions are formed. 23a and 23b constitute a holding portion 23 having a diameter larger than that of the mounting portion 121 provided at the base end portion of the base portion 12 and rotatably holding the mounting portion 121. As shown in FIGS. 2 and 4, the pin receiver 2 faces away from the accommodation position (p) where the needle tip 11 is accommodated in the accommodation groove 21 and the accommodation position (p). That is, it can be rotated between the accommodation position (p) and the retracted position (q) located on the opposite side of 180 degrees. Note that the pin receiver 2 may be rotatably attached to the base 12 by another mechanism.
[0016]
Thus, when the safety pin A is mounted on, for example, a cloth of clothing that is a mounting target, the needle tip 11 is inserted with the pin receiver 2 positioned at the retracted position (q). Next, when the pin 1 is fixed so as not to move by hand and the pin receiver 2 is rotated toward the needle tip portion 11 side, the needle tip portion 11 is received in the receiving groove 21 as shown in FIG. Is done. That is, when the housing groove 21 is positioned so as to face the needle tip portion 11 (a), and the pin receiver 2 is slightly pressed against the needle tip portion 11, the needle tip portion 11 is formed into the protrusion 22. The side edge portion 24 that is in contact with the outer surface 22a of the tapered shape and is located outward from the projection 22 and the wall surface 21b is pushed over the outer space (b), and the pin receiver 2 is moved to the accommodation position (p). Will be positioned (c). At this time, the pin receiver 2 may be rotated in a state in which the needle tip portion 11 is slightly moved toward the base portion 12 so that the insertion operation into the accommodation groove 21 of the needle tip portion 11 may be smoother. On the other hand, when removing the safety pin A, the pin holder 2 is rotated so that the needle tip portion 11 gets over the protrusion 22 and is removed from the accommodation groove. At this time, the needle tip 11 is guided to the outer surface 22 a of the protrusion 22 and moves toward the opening 21 a of the receiving groove 21.
[0017]
As described above, the safety pin A in the present embodiment rotates the pin receiver 2 side so as to accommodate the needle tip portion 11 in the accommodation groove 21, so that the pin portion is elastic as in a conventional safety pin. It does not require a large force to be deformed, and can be mounted only by a rotating operation. That is, it can be easily used for weak women, children, elderly people, and the like. Furthermore, since it is not necessary to adjust the position of the thin needle tip portion 11, it is easy to mount even if it is difficult to see the hand.
[0018]
Further, since the receiving groove 21 is formed in the vicinity of the side edge portion of the pin receiver 2, the thickness dimension of the side edge portion 24 is thinner than the wall surface 21b, and together with the protrusion 22 formed on the wall surface 21b when the needle tip portion 11 is inserted. It can be elastically deformed and easily moved to the outer space, and can be inserted smoothly. It is formed so as to narrow inward from the side edge portion side of the pin receiver.
[0019]
Since the protrusion 22 is formed in a substantially hemispherical shape, the needle tip portion 11 can be smoothly inserted into the receiving groove by being guided by the outer peripheral surface 22a functioning as a tapered surface, and further, the removal can be smoothly performed.
[0020]
Since the pin receiver 2 can be rotated to the retracted position (q) facing away from the accommodation position (p), when the pin receiver 2 is mounted on the mounting object, it interferes with the insertion of the needle tip 11. Don't be.
[0021]
Moreover, since the spherical body 3 which is a restricting member is attached to the boundary portion (intermediate position) between the needle tip portion 11 and the base portion 12, the attachment target does not shift in the attachment state. Further, the design can be improved by coloring the sphere 3 in the same color as the pin holder 2 or in a different color. It is also easy to grasp when lifting the safety pin A. The restricting member may have a shape other than a spherical shape.
[0022]
The present invention is not limited to the above embodiment.
[0023]
For example, safety pins B, C, and D as shown in FIGS. 6 to 8 may be used. In the figure, those having the same functions and configurations as those of the above embodiment are denoted by “B”, “C”, and [D] at the beginning of the same reference numerals.
[0024]
First, as shown in the plan view in FIG. 6, the safety pin B may be provided with protrusions B22 and B22 ′ as latching portions protruding from both wall surfaces B21b and B21c constituting the housing groove B21.
[0025]
Then, as shown in the plan view of FIG. 7, a wall surface C21c constituting the housing groove C21 is formed by forming a notch C25 in the vicinity of the wall surface C21c from which the projection C22 ′ similar to the projection B22 ′ is projected. The safety pin C may be such that the thickness width dimension of the wall portion C26 to be reduced is reduced. In such a case, when the needle tip portion C11 is inserted, the side edge portion C24 and the wall portion C26 move so as to escape into the outer space and the notch C25, respectively, when getting over the protrusions C22, C22 ′. The opening width is wide and can be inserted smoothly.
