一対の台座部材１５は、ステンレス等の金属により形成される略コ字状（略Ｕ字状）の金具である。台座部材１５の開口側の端部は容器本体１１の外周面に溶接等で固定されている。一対の台座部材１５は、容器１０の径方向に互いに対向する位置に配置される。台座部材１５には、パチン錠４０がねじ等を通じて固定されている。 As shown in FIG. 1, the portable container 1 includes a container 10, a lid 20, a pair of snap locks 40, and a pair of handles 50.
The container 10 includes a container body 11, a pair of pedestal members 15 to which the snap lock 40 is fixed, and a pair of handle support members 18 that support the handle 50.
The container body 11 is formed in a bottomed cylindrical shape that opens upward. The container body 11 is made of a metal such as stainless steel.
The pair of pedestal members 15 are substantially U-shaped (substantially U-shaped) metal fittings formed of a metal such as stainless steel. The end of the pedestal member 15 on the opening side is fixed to the outer peripheral surface of the container body 11 by welding or the like. The pair of pedestal members 15 are arranged at positions facing each other in the radial direction of the container 10. A snap lock 40 is fixed to the pedestal member 15 through screws or the like.

一対のハンドル支持部材１８は、ステンレス等の金属により形成され、容器本体１１の外周面に向けて開口する略コ字状の金具である。一対のハンドル支持部材１８の開口側の端部は容器本体１１の外周面に溶接等で固定されている。一対のハンドル支持部材１８は、容器１０の径方向に互いに対向する位置に配置される。各ハンドル支持部材１８における容器本体１１の周方向に並ぶ２つの壁部１８ｂには貫通する孔１８ａが形成されている。ハンドル支持部材１８の各孔１８ａには、ハンドル５０が回転可能にハンドル５０の端部が挿入されている。例えば、一対のハンドル支持部材１８が並ぶ方向と一対の台座部材１５が並ぶ方向は直交している。 The pair of handle support members 18 are substantially U-shaped metal fittings formed of a metal such as stainless steel and open toward the outer peripheral surface of the container body 11. The ends of the pair of handle support members 18 on the opening side are fixed to the outer peripheral surface of the container body 11 by welding or the like. The pair of handle support members 18 are arranged at positions facing each other in the radial direction of the container 10. Holes 18a are formed in the two wall portions 18b arranged in the circumferential direction of the container body 11 in each handle support member 18. An end portion of the handle 50 is inserted into each hole 18a of the handle support member 18 so that the handle 50 can rotate. For example, the direction in which the pair of handle support members 18 are arranged and the direction in which the pair of pedestal members 15 are arranged are orthogonal to each other.

図１に示すように、蓋２０は、ステンレス等の金属により、容器本体１１の開口部を塞ぐ略円板状をなす。蓋２０は、蓋２０の外周面に位置し、パチン錠４０の後述するフック部材４４が係止される一対の被係止部材２３を備える。被係止部材２３は略Ｊ字状の金具である。一対の被係止部材２３は、蓋２０の径方向に沿って互いに対向する位置に配置される。 As shown in FIG. 1, the lid 20 has a substantially disk shape that closes the opening of the container body 11 with a metal such as stainless steel. The lid 20 is located on the outer peripheral surface of the lid 20 and includes a pair of locked members 23 to which the hook member 44 described later of the snap lock 40 is locked. The locked member 23 is a substantially J-shaped metal fitting. The pair of locked members 23 are arranged at positions facing each other along the radial direction of the lid 20.

一対のハンドル５０は人の手により把持可能な略Ｕ字状に形成される。ハンドル５０の開口側の端部は、ハンドル支持部材１８の孔１８ａに挿入されるように内側に折り曲げられてなる。よって、ハンドル５０は孔１８ａを中心に回転可能にハンドル支持部材１８に支持される。 The pair of handles 50 are formed in a substantially U shape that can be grasped by a human hand. The opening-side end of the handle 50 is bent inward so as to be inserted into the hole 18a of the handle support member 18. Therefore, the handle 50 is rotatably supported by the handle support member 18 about the hole 18a.

図２（ａ），（ｂ）に示すように、パチン錠４０は、ベース部材４１と、レバー部材４３と、フック部材４４と、トーションばね４７と、を備える。 As shown in FIGS. 2A and 2B, the snap lock 40 includes a base member 41, a lever member 43, a hook member 44, and a torsion spring 47.

図３に示すように、ベース部材４１は、板状に形成されるベース本体部４１ａと、支持ピン４５と、支持ピン４５の両端を支持するピン支持壁４１ｂ，４１ｃと、リング保持部４１ｄと、を備える。
ピン支持壁４１ｂ，４１ｃは、ベース本体部４１ａの上端に位置し、幅方向Ｗに沿って並べられ、互いに対面する。ピン支持壁４１ｂ，４１ｃには、それぞれ、支持ピン４５が挿通される貫通孔４１ｈが形成される。 As shown in FIG. 3, the base member 41 includes a base body portion 41a formed in a plate shape, a support pin 45, pin support walls 41b and 41c for supporting both ends of the support pin 45, and a ring holding portion 41d. , Equipped with.
The pin support walls 41b and 41c are located at the upper ends of the base main body 41a, are arranged along the width direction W, and face each other. Through holes 41h through which the support pins 45 are inserted are formed in the pin support walls 41b and 41c, respectively.

図４に示すように、リング保持部４１ｄは、ベース本体部４１ａの上端であって、ピン支持壁４１ｂ，４１ｃの間に位置する。リング保持部４１ｄは、ベース本体部４１ａの上端面との間に隙間Ｓ１を有するＬ字状に形成されている。リング保持部４１ｄは、幅方向Ｗに沿って延びるバー部４１ｆと、バー部４１ｆに対して屈曲し、高さ方向Ｈに沿って延びる抜け止め部４１ｇと、を備える。バー部４１ｆにおける抜け止め部４１ｇから遠い基端部４１ｉは、ピン支持壁４１ｃにおけるベース本体部４１ａ側の端部に設けられる。バー部４１ｆの基端部４１ｉは、バー部４１ｆにおける基端部４１ｉ以外の部位よりも高さ方向Ｈの厚さが薄い薄肉部として形成される。このため、図７に示すように、リング保持部４１ｄは、外力により、薄肉部である基端部４１ｉを中心に回転容易となる。この際、リング保持部４１ｄの基端部４１ｉは塑性変形する。 As shown in FIG. 4, the ring holding portion 41d is the upper end of the base main body portion 41a and is located between the pin support walls 41b and 41c. The ring holding portion 41d is formed in an L shape having a gap S1 between the ring holding portion 41d and the upper end surface of the base main body portion 41a. The ring holding portion 41d includes a bar portion 41f extending along the width direction W and a retaining portion 41g bent with respect to the bar portion 41f and extending along the height direction H. The base end portion 41i of the bar portion 41f, which is far from the retaining portion 41g, is provided at the end portion of the pin support wall 41c on the base main body portion 41a side. The base end portion 41i of the bar portion 41f is formed as a thin-walled portion having a thickness in the height direction H thinner than a portion of the bar portion 41f other than the base end portion 41i. Therefore, as shown in FIG. 7, the ring holding portion 41d can easily rotate around the base end portion 41i, which is a thin-walled portion, due to an external force. At this time, the base end portion 41i of the ring holding portion 41d is plastically deformed.

図４に示すように、バー部４１ｆは、ベース本体部４１ａの上端面に対して隙間Ｓ１を持って幅方向Ｗに延びる。トーションばね４７の後述する第１ばね端部４７ｂは、隙間Ｓ１を通って、バー部４１ｆの周囲を囲む。抜け止め部４１ｇは、バー部４１ｆの先端部からベース本体部４１ａの上端面に向けて延びて、ベース本体部４１ａの上端面に接触又は接近する。抜け止め部４１ｇとベース本体部４１ａの上端面の隙間Ｓ３（図７参照）は、トーションばね４７の線材径Ｄよりも小さく設定される。抜け止め部４１ｇの先端面は膨らむように湾曲した形状をなす。ベース本体部４１ａの上端面には、抜け止め部４１ｇの先端面に応じた湾曲した凹部４１ｊが形成される。 As shown in FIG. 4, the bar portion 41f extends in the width direction W with a gap S1 with respect to the upper end surface of the base main body portion 41a. The first spring end portion 47b, which will be described later, of the torsion spring 47 passes through the gap S1 and surrounds the periphery of the bar portion 41f. The retaining portion 41g extends from the tip end portion of the bar portion 41f toward the upper end surface of the base main body portion 41a, and comes into contact with or approaches the upper end surface of the base main body portion 41a. The gap S3 (see FIG. 7) between the retaining portion 41g and the upper end surface of the base main body portion 41a is set to be smaller than the wire diameter D of the torsion spring 47. The tip surface of the retaining portion 41g has a curved shape so as to bulge. A curved recess 41j corresponding to the tip surface of the retaining portion 41g is formed on the upper end surface of the base main body portion 41a.

図２（ａ），（ｂ）に示すように、レバー部材４３は、ベース部材４１の支持ピン４５を中心に回転可能に支持されつつ、フック部材４４を回転可能に支持する。
レバー部材４３は、レバー本体部４３ａと、一対の側壁４３ｂ，４３ｃと、一対の回転支持壁４３ｄ，４３ｅと、防護壁４３ｆと、操作部４３ｇと、を備える。
レバー本体部４３ａは高さ方向Ｈに長い長方形板状をなす。操作部４３ｇは、レバー本体部４３ａにおける支持ピン４５から遠い先端側に位置し、レバー本体部４３ａと同じ方向に延びる板状をなす。 As shown in FIGS. 2A and 2B, the lever member 43 rotatably supports the hook member 44 while being rotatably supported around the support pin 45 of the base member 41.
The lever member 43 includes a lever main body portion 43a, a pair of side walls 43b, 43c, a pair of rotary support walls 43d, 43e, a protective wall 43f, and an operation portion 43g.
The lever body 43a has a rectangular plate shape that is long in the height direction H. The operation unit 43g is located on the tip side of the lever body 43a far from the support pin 45, and has a plate shape extending in the same direction as the lever body 43a.

一対の側壁４３ｂ，４３ｃは、レバー本体部４３ａの幅方向Ｗの両縁部に沿って延び、幅方向Ｗに沿って並べられ、互いに対面する。一対の側壁４３ｂ，４３ｃは、幅方向Ｗにおいて、ベース部材４１のピン支持壁４１ｂ，４１ｃを外側から挟み込むように位置する。側壁４３ｂ，４３ｃにおけるレバー本体部４３ａを基準とした高さは、操作部４３ｇに近づくにつれて低くなる。図２（ｂ）に示すように、側壁４３ｂ，４３ｃには、それぞれ、フック部材４４の後述するフック端部４４ａ，４４ｂが通過する貫通孔４３ｈが形成される。 The pair of side walls 43b and 43c extend along both edges of the lever body portion 43a in the width direction W, are arranged along the width direction W, and face each other. The pair of side walls 43b, 43c are positioned so as to sandwich the pin support walls 41b, 41c of the base member 41 from the outside in the width direction W. The height of the side walls 43b and 43c with respect to the lever main body 43a becomes lower as it approaches the operating portion 43g. As shown in FIG. 2B, through holes 43h through which hook ends 44a and 44b, which will be described later, of the hook member 44 pass, are formed in the side walls 43b and 43c, respectively.

図２（ａ）に示すように、レバー部材４３がベース部材４１に対して閉じられたときに、一対の側壁４３ｂ，４３ｃにおけるレバー本体部４３ａから遠い端面４３ｓはベース部材４１のベース本体部４１ａの上面に接触する。これにより、レバー部材４３が閉じられたときにおける操作部４３ｇと容器本体１１の外周面の距離を保つことができる。よって、レバー部材４３を開く際に、操作部４３ｇと容器本体１１の外周面の間に手指を挿入させやすく、レバー部材４３を開く操作が容易となる。 As shown in FIG. 2A, when the lever member 43 is closed with respect to the base member 41, the end faces 43s of the pair of side walls 43b and 43c far from the lever main body 43a are the base main body 41a of the base member 41. Contact the top surface of. As a result, the distance between the operating portion 43g and the outer peripheral surface of the container body 11 when the lever member 43 is closed can be maintained. Therefore, when opening the lever member 43, it is easy to insert a finger between the operating portion 43g and the outer peripheral surface of the container body 11, and the operation of opening the lever member 43 becomes easy.

図３に示すように、防護壁４３ｆは、レバー本体部４３ａにおける操作部４３ｇと反対側の縁部に設けられ、回転支持壁４３ｄ，４３ｅの間に位置する。防護壁４３ｆは、トーションばね４７の後述するコイル部４７ａの周囲を囲むＪ字又はＣ字状をなす。言い換えると、防護壁４３ｆは、レバー部材４３が閉じられた状態で、防護壁４３ｆの先端に向かうにつれてベース部材４１に近づくように湾曲する。防護壁４３ｆは、異物がトーションばね４７に接触することを抑制する機能を有する。 As shown in FIG. 3, the protective wall 43f is provided on the edge of the lever main body 43a on the opposite side of the operating portion 43g, and is located between the rotary support walls 43d and 43e. The protective wall 43f has a J-shape or a C-shape that surrounds the coil portion 47a described later of the torsion spring 47. In other words, the protective wall 43f is curved so as to approach the base member 41 toward the tip of the protective wall 43f with the lever member 43 closed. The protective wall 43f has a function of suppressing foreign matter from coming into contact with the torsion spring 47.

図３に示すように、回転支持壁４３ｄ，４３ｅは、それぞれ、側壁４３ｂ，４３ｃの上部に位置し、幅方向Ｗに沿って並べられ、互いに対面する。回転支持壁４３ｄ，４３ｅは、幅方向Ｗにおいて、ピン支持壁４１ｂ，４１ｃを挟み込むように位置する。回転支持壁４３ｄ，４３ｅには、回転支持壁４３ｄ，４３ｅの厚さ方向に貫通する貫通孔４３ｊが形成されている。回転支持壁４３ｄ，４３ｅの一対の貫通孔４３ｊの中心軸と、ピン支持壁４１ｂ，４１ｃの一対の貫通孔４１ｈの中心軸は幅方向Ｗに一致する。 As shown in FIG. 3, the rotary support walls 43d and 43e are located above the side walls 43b and 43c, respectively, are arranged along the width direction W, and face each other. The rotary support walls 43d and 43e are positioned so as to sandwich the pin support walls 41b and 41c in the width direction W. The rotary support walls 43d and 43e are formed with through holes 43j that penetrate the rotary support walls 43d and 43e in the thickness direction. The central axes of the pair of through holes 43j of the rotary support walls 43d and 43e and the central axes of the pair of through holes 41h of the pin support walls 41b and 41c coincide with each other in the width direction W.

図２（ｂ）に示すように、フック部材４４は線材が略矩形状をなすように折り曲げられてなる。フック部材４４は、レバー部材４３の内部空間において互いに対向する一対のフック端部４４ａ，４４ｂを備える。フック端部４４ａ，４４ｂは、フック部材４４の長手方向（高さ方向Ｈ）に対して直交する方向に互いに近づくように屈曲されている。 As shown in FIG. 2B, the hook member 44 is bent so that the wire rod has a substantially rectangular shape. The hook member 44 includes a pair of hook end portions 44a and 44b facing each other in the internal space of the lever member 43. The hook end portions 44a and 44b are bent so as to approach each other in a direction orthogonal to the longitudinal direction (height direction H) of the hook member 44.

図５に示すように、フック端部４４ａ，４４ｂは、レバー部材４３の一対の側壁４３ｂ，４３ｃの貫通孔４３ｈに挿通される。一対のフック端部４４ａ，４４ｂは、一対の被挿通部の一例であり、幅方向Ｗにおいて隙間Ｓ２を持って対向するように位置する。一対のフック端部４４ａ，４４ｂの間の隙間Ｓ２には、一対のフック端部４４ａ，４４ｂを接続する連結部４４ｄが設けられる。隙間Ｓ２は、トーションばね４７の線材径Ｄよりも大きく形成される。連結部４４ｄは、溶接に伴う溶加材が硬化することにより形成される。フック部材４４は、側壁４３ｂ，４３ｃの各貫通孔４３ｈを中心に回動可能である。図１に示すように、フック部材４４におけるレバー部材４３から遠い先端部４４ｃは、蓋２０の被係止部材２３に係止される。 As shown in FIG. 5, the hook ends 44a and 44b are inserted into the through holes 43h of the pair of side walls 43b and 43c of the lever member 43. The pair of hook end portions 44a and 44b are an example of a pair of inserted portions, and are located so as to face each other with a gap S2 in the width direction W. A connecting portion 44d for connecting the pair of hook end portions 44a and 44b is provided in the gap S2 between the pair of hook end portions 44a and 44b. The gap S2 is formed larger than the wire diameter D of the torsion spring 47. The connecting portion 44d is formed by hardening the filler metal that accompanies welding. The hook member 44 can rotate around the through holes 43h of the side walls 43b and 43c. As shown in FIG. 1, the tip portion 44c of the hook member 44 far from the lever member 43 is locked to the locked member 23 of the lid 20.

図２（ｂ）に示すように、トーションばね４７は、レバー部材４３をベース部材４１に向けて閉じる方向に付勢する。トーションばね４７は１本の線材が巻かれることにより形成される。
詳しくは、図６に示すように、トーションばね４７は、コイル部４７ａと、第１ばね端部４７ｂと、第２ばね端部４７ｃと、を備える。
図４に示すように、コイル部４７ａ内には支持ピン４５が挿通される。よって、コイル部４７ａは支持ピン４５の周囲に位置する。コイル部４７ａの周囲の上部には防護壁４３ｆが位置する。幅方向Ｗにおいて、コイル部４７ａの長さは防護壁４３ｆよりも長く形成されている。すなわち、高さ方向Ｈから見て、コイル部４７ａの幅方向Ｗの両端は防護壁４３ｆからはみ出している。 As shown in FIG. 2B, the torsion spring 47 urges the lever member 43 toward the base member 41 in a closing direction. The torsion spring 47 is formed by winding one wire rod.
Specifically, as shown in FIG. 6, the torsion spring 47 includes a coil portion 47a, a first spring end portion 47b, and a second spring end portion 47c.
As shown in FIG. 4, the support pin 45 is inserted into the coil portion 47a. Therefore, the coil portion 47a is located around the support pin 45. A protective wall 43f is located above the periphery of the coil portion 47a. In the width direction W, the length of the coil portion 47a is formed longer than that of the protective wall 43f. That is, when viewed from the height direction H, both ends of the coil portion 47a in the width direction W protrude from the protective wall 43f.

図６に示すように、第１ばね端部４７ｂは、コイル部４７ａの一端部に位置し、リング状に形成される。第１ばね端部４７ｂの中心軸は、コイル部４７ａの中心軸から離れた位置に形成される。コイル部４７ａの中心軸に沿う方向から見て、コイル部４７ａ及び第１ばね端部４７ｂは８の字状をなす。第１ばね端部４７ｂは、コイル部４７ａの一端から延びる線材が３６０°〜５４０°にわたって巻かれることにより形成される。第１ばね端部４７ｂの先端部４７ｂ１は下方向を向くように設定される。これにより、第１ばね端部４７ｂの先端部４７ｂ１に、異物、手指又は手袋等が引っ掛かることが抑制される。図４に示すように、第１ばね端部４７ｂ内には、ベース部材４１のリング保持部４１ｄが挿通される。 As shown in FIG. 6, the first spring end portion 47b is located at one end portion of the coil portion 47a and is formed in a ring shape. The central axis of the first spring end portion 47b is formed at a position away from the central axis of the coil portion 47a. When viewed from the direction along the central axis of the coil portion 47a, the coil portion 47a and the first spring end portion 47b form a figure of eight. The first spring end portion 47b is formed by winding a wire rod extending from one end of the coil portion 47a over 360 ° to 540 °. The tip end portion 47b1 of the first spring end portion 47b is set so as to face downward. As a result, foreign matter, fingers, gloves, etc. are prevented from being caught on the tip portion 47b1 of the first spring end portion 47b. As shown in FIG. 4, the ring holding portion 41d of the base member 41 is inserted into the first spring end portion 47b.

図６に示すように、第２ばね端部４７ｃは、コイル部４７ａの他端部に位置し、リング状に形成される。第２ばね端部４７ｃの中心軸は、コイル部４７ａの中心軸から離れた位置に形成される。第２ばね端部４７ｃは、第１ばね端部４７ｂに比べて、コイル部４７ａから遠い位置に設けられる。第２ばね端部４７ｃは、コイル部４７ａの他端から延びる線材が３６０°〜５４０°にわたって巻かれることにより形成される。第１ばね端部４７ｂと第２ばね端部４７ｃで巻かれる方向は互いに逆となる。図５に示すように、第２ばね端部４７ｃ内にはフック部材４４のフック端部４４ｂに挿通される。 As shown in FIG. 6, the second spring end portion 47c is located at the other end of the coil portion 47a and is formed in a ring shape. The central axis of the second spring end portion 47c is formed at a position away from the central axis of the coil portion 47a. The second spring end portion 47c is provided at a position farther from the coil portion 47a than the first spring end portion 47b. The second spring end portion 47c is formed by winding a wire rod extending from the other end of the coil portion 47a over 360 ° to 540 °. The directions of winding by the first spring end portion 47b and the second spring end portion 47c are opposite to each other. As shown in FIG. 5, the hook end portion 44b of the hook member 44 is inserted into the second spring end portion 47c.

次に、パチン錠４０の組み立て方法について説明する。この組み立て作業は、人により行われる。この組み立て開始前には、一対のフック端部４４ａ，４４ｂの間の隙間Ｓ２に連結部４４ｄが形成されていない。また、図７に示すように、ベース部材４１のリング保持部４１ｄの抜け止め部４１ｇは、ベース本体部４１ａの上端面の凹部４１ｊから隙間Ｓ３だけ離れている。隙間Ｓ３は、トーションばね４７の第１ばね端部４７ｂが通過可能に、トーションばね４７の線材径Ｄよりも大きく形成される。 Next, a method of assembling the snap lock 40 will be described. This assembly work is done by a person. Before the start of this assembly, the connecting portion 44d is not formed in the gap S2 between the pair of hook end portions 44a and 44b. Further, as shown in FIG. 7, the retaining portion 41g of the ring holding portion 41d of the base member 41 is separated from the recess 41j of the upper end surface of the base main body portion 41a by a gap S3. The gap S3 is formed to be larger than the wire diameter D of the torsion spring 47 so that the first spring end portion 47b of the torsion spring 47 can pass through.

まず、図５に示すように、フック部材４４をフック端部４４ａ，４４ｂが互いに離れるように弾性変形させた状態で、フック端部４４ａ，４４ｂをそれぞれレバー部材４３の外側から一対の貫通孔４３ｈに挿入する。
次に、トーションばね４７の第２ばね端部４７ｃを一対のフック端部４４ａ，４４ｂの間の隙間Ｓ２を通過させて、第２ばね端部４７ｃ内にフック端部４４ｂを挿通させる。また、図７に示すように、トーションばね４７の第１ばね端部４７ｂ内に、リング保持部４１ｄのバー部４１ｆを挿通する。 First, as shown in FIG. 5, in a state where the hook member 44 is elastically deformed so that the hook end portions 44a and 44b are separated from each other, the hook end portions 44a and 44b are respectively subjected to a pair of through holes 43h from the outside of the lever member 43. Insert in.
Next, the second spring end portion 47c of the torsion spring 47 is passed through the gap S2 between the pair of hook end portions 44a and 44b, and the hook end portion 44b is inserted into the second spring end portion 47c. Further, as shown in FIG. 7, the bar portion 41f of the ring holding portion 41d is inserted into the first spring end portion 47b of the torsion spring 47.

次に、図３に示すように、回転支持壁４３ｄ、４３ｅの間にピン支持壁４１ｂ、４１ｅを配置し、支持ピン４５を回転支持壁４３ｄ，４３ｅの一対の貫通孔４３ｊとピン支持壁４１ｂ，４１ｃの一対の貫通孔４１ｈに挿入する。この際、支持ピン４５をトーションばね４７のコイル部４７ａ内に通す。そして、支持ピン４５の両端部をつぶすことにより、支持ピン４５の両端部を貫通孔４１ｈ，４３ｊの径よりも大きくする。これにより、支持ピン４５は、貫通孔４１ｈ，４３ｊ内に抜け止め状態となる。 Next, as shown in FIG. 3, the pin support walls 41b and 41e are arranged between the rotation support walls 43d and 43e, and the support pins 45 are provided by the pair of through holes 43j and the pin support walls 41b of the rotation support walls 43d and 43e. , 41c are inserted into the pair of through holes 41h. At this time, the support pin 45 is passed through the coil portion 47a of the torsion spring 47. Then, by crushing both ends of the support pin 45, both ends of the support pin 45 are made larger than the diameters of the through holes 41h and 43j. As a result, the support pin 45 is put into a retaining state in the through holes 41h and 43j.

次に、図７に示すように、リング保持部４１ｄの抜け止め部４１ｇがベース本体部４１ａの凹部４１ｊに近づくように、基端部４１ｉを中心にリング保持部４１ｄを回転させる。これにより、抜け止め部４１ｇと凹部４１ｊの間の隙間Ｓ３がトーションばね４７の線材径Ｄ未満となる。また、幅方向Ｗにおいて、第１のばね端部４７ｂは、バー部４１ｆとベース本体部４１ａの上端面の間の隙間Ｓ１内でのみ保持された状態となる。従って、第１ばね端部４７ｂがトーションばね４７から脱落した場合であっても、第１ばね端部４７ｂ内にバー部４１ｆが挿通された状態が維持される。よって、第１ばね端部４７ｂが破片としてパチン錠４０から離脱することが抑制される。
そして、図５に示すように、フック端部４４ａ，４４ｂの間の隙間Ｓ２を溶接により連結部４４ｄで埋める。従って、第２ばね端部４７ｃがトーションばね４７から破断し、脱落した場合であっても、第２ばね端部４７ｃ内にフック端部４４ｂが挿通された状態が維持される。よって、第２ばね端部４７ｃが破片としてパチン錠４０から離脱することが抑制される。なお、連結部４４ｄは必ずしも溶接する必要はなく、フック端部４４ａ、４４ｂの間の隙間Ｓ２を第２ばね端部４７ｃの線材径Ｄ以下としてもよい。
以上で、パチン錠４０の組み立てが完了となる。 Next, as shown in FIG. 7, the ring holding portion 41d is rotated around the base end portion 41i so that the retaining portion 41g of the ring holding portion 41d approaches the recess 41j of the base main body portion 41a. As a result, the gap S3 between the retaining portion 41g and the recess 41j becomes smaller than the wire diameter D of the torsion spring 47. Further, in the width direction W, the first spring end portion 47b is held only in the gap S1 between the bar portion 41f and the upper end surface of the base main body portion 41a. Therefore, even when the first spring end portion 47b falls off from the torsion spring 47, the state in which the bar portion 41f is inserted into the first spring end portion 47b is maintained. Therefore, it is suppressed that the first spring end portion 47b is separated from the snap lock 40 as a fragment.
Then, as shown in FIG. 5, the gap S2 between the hook end portions 44a and 44b is filled with the connecting portion 44d by welding. Therefore, even if the second spring end portion 47c breaks from the torsion spring 47 and falls off, the state in which the hook end portion 44b is inserted into the second spring end portion 47c is maintained. Therefore, it is suppressed that the second spring end portion 47c is separated from the snap lock 40 as a fragment. The connecting portion 44d does not necessarily have to be welded, and the gap S2 between the hook end portions 44a and 44b may be set to the wire diameter D or less of the second spring end portion 47c.
This completes the assembly of the snap lock 40.

次に、パチン錠４０により蓋２０を容器本体１１に固定する手順について説明する。
容器本体１１に食品を収容した後、蓋２０を閉める。そして、図２（ｂ）に示すように、パチン錠４０において、トーションばね４７の弾性力に抗して、レバー部材４３をベース部材４１に対して離れる方向に開く。図１に示すように、フック部材４４の先端部４４ｃを蓋２０の被係止部材２３に引っ掛ける。この状態で、図２（ａ）に示すように、レバー部材４３をベース部材４１に近づける方向に閉じる。これにより、蓋２０が容器本体１１に固定される。 Next, a procedure for fixing the lid 20 to the container body 11 with the snap lock 40 will be described.
After storing the food in the container body 11, the lid 20 is closed. Then, as shown in FIG. 2B, in the snap lock 40, the lever member 43 is opened in the direction away from the base member 41 against the elastic force of the torsion spring 47. As shown in FIG. 1, the tip portion 44c of the hook member 44 is hooked on the locked member 23 of the lid 20. In this state, as shown in FIG. 2A, the lever member 43 is closed in the direction closer to the base member 41. As a result, the lid 20 is fixed to the container body 11.

（効果）
以上、説明した一実施形態によれば、以下の効果を奏する。
（１）パチン錠４０は、支持ピン４５を有し、被装着面である台座部材１５に固定されるベース部材４１と、支持ピン４５を中心にベース部材４１に対して回転可能に支持されるレバー部材４３と、レバー部材４３に回転可能に支持され、被係止部材２３に係止可能なフック部材４４と、レバー部材４３をベース部材４１に向けて付勢するトーションばね４７と、を備える。トーションばね４７は、支持ピン４５が挿通されるコイル部４７ａと、コイル部４７ａの一端に位置し、ベース部材４１に連結する第１ばね端部４７ｂと、コイル部４７ａの他端に位置し、フック部材４４に連結する第２ばね端部４７ｃと、を備える。第１ばね端部４７ｂは、リング状に形成され、連結するベース部材４１に形成される被挿通部に相当するバー部４１ｆに挿通される。第２ばね端部４７ｃは、リング状に形成され、連結するフック部材４４に形成される被挿通部に相当するフック端部４４ｂに挿通される。
この構成によれば、トーションばね４７の第１ばね端部４７ｂがベース部材４１から外れること、ひいては、トーションばね４７が空回りすることが抑制される。
また、トーションばね４７の第２ばね端部４７ｃがフック部材４４から外れること、ひいては、トーションばね４７が空回りすることが抑制される。
以上により、レバー部材４３の開閉に伴い、トーションばね４７が空回りすることが抑制され、これにより、より確実に、トーションばね４７を機能させることができ、パチン錠４０により蓋２０を容器本体１１に固定することが可能となる。
また、第１ばね端部４７ｂ及び第２ばね端部４７ｃはリング状をなす。このため、第１ばね端部４７ｂ及び第２ばね端部４７ｃの先端は外部に向かって突出しない。このため、第１ばね端部４７ｂ及び第２ばね端部４７ｃの先端が手指等に接触することが抑制される。これにより、作業者が手袋を着用している場合、第１ばね端部４７ｂ及び第２ばね端部４７ｃの先端により手袋に傷がつくことが抑制される。 (effect)
According to the embodiment described above, the following effects are obtained.
(1) The snap lock 40 has a support pin 45 and is rotatably supported by a base member 41 fixed to a pedestal member 15 which is a mounting surface and a base member 41 around the support pin 45. It includes a lever member 43, a hook member 44 that is rotatably supported by the lever member 43 and can be locked to the locked member 23, and a torsion spring 47 that urges the lever member 43 toward the base member 41. .. The torsion spring 47 is located at one end of the coil portion 47a through which the support pin 45 is inserted and one end of the coil portion 47a, and is located at the other end of the first spring end portion 47b connected to the base member 41 and the coil portion 47a. A second spring end portion 47c connected to the hook member 44 is provided. The first spring end portion 47b is formed in a ring shape and is inserted into the bar portion 41f corresponding to the insertion portion formed in the connecting base member 41. The second spring end portion 47c is formed in a ring shape and is inserted into the hook end portion 44b corresponding to the inserted portion formed in the hook member 44 to be connected.
According to this configuration, it is possible to prevent the first spring end portion 47b of the torsion spring 47 from coming off from the base member 41, and thus the torsion spring 47 from idling.
Further, it is prevented that the second spring end portion 47c of the torsion spring 47 is detached from the hook member 44, and that the torsion spring 47 is prevented from idling.
As described above, the torsion spring 47 is suppressed from idling as the lever member 43 is opened and closed, whereby the torsion spring 47 can be operated more reliably, and the lid 20 is attached to the container body 11 by the snap lock 40. It can be fixed.
Further, the first spring end portion 47b and the second spring end portion 47c form a ring shape. Therefore, the tips of the first spring end portion 47b and the second spring end portion 47c do not protrude outward. Therefore, it is suppressed that the tips of the first spring end portion 47b and the second spring end portion 47c come into contact with the fingers or the like. As a result, when the worker wears gloves, the tips of the first spring end portion 47b and the second spring end portion 47c prevent the gloves from being scratched.

（２）ベース部材４１は、板状のベース本体部４１ａと、ベース本体部４１ａの端面に隙間Ｓ１を持ってコイル部４７ａの軸方向に沿う幅方向Ｗに延び、リング状の第１ばね端部４７ｂ内に挿通される被挿通部であるバー部４１ｆと、バー部４１ｆの端部に設けられ、幅方向Ｗにおいて隙間Ｓ１を閉じるように、ベース本体部４１ａの端面に接近又は接触する抜け止め部４１ｇと、を備える。
この構成によれば、トーションばね４７の第１ばね端部４７ｂが折れた場合でも、リング状の第１ばね端部４７ｂはバー部４１ｆの外周に保持される。 (2) The base member 41 has a gap S1 between the plate-shaped base main body 41a and the end faces of the base main body 41a and extends in the width direction W along the axial direction of the coil 47a, and is a ring-shaped first spring end. A hole that is provided at the end of the bar portion 41f and the bar portion 41f that is inserted into the portion 47b and approaches or contacts the end surface of the base main body portion 41a so as to close the gap S1 in the width direction W. It is provided with a stop portion 41 g.
According to this configuration, even when the first spring end portion 47b of the torsion spring 47 is broken, the ring-shaped first spring end portion 47b is held on the outer circumference of the bar portion 41f.

（３）レバー部材４３は、板状のレバー本体部４３ａと、レバー本体部４３ａの縁部に形成され、コイル部４７ａの軸方向に沿う幅方向Ｗに並び、互いに対面する一対の側壁４３ｂ，４３ｃと、を備える。フック部材４４は、一対の側壁４３ｂ，４３ｃに形成される貫通孔４３ｈに挿通され、一対の側壁４３ｂ，４３ｃの間において対向する被挿通部である一対のフック端部４４ａ，４４ｂを備える。リング状の第２ばね端部４７ｃ内には一対のフック端部４４ａ，４４ｂのうち一方のフック端部４４ｂが挿通される。
この構成によれば、トーションばね４７の第２ばね端部４７ｃが折れた場合でも、リング状の第２ばね端部４７ｃはフック端部４４ａ，４４ｂの外周に保持される。
さらに、一対のフック端部４４ａ，４４ｂは、トーションばね４７の線材径Ｄよりも大きい隙間Ｓ２を持って対向し、フック部材４４は、一対のフック端部４４ａ，４４ｂを連結する連結部４４ｄを備える。
この構成によれば、隙間Ｓ２が大きくなるようにフック部材４４を弾性変形させることなく、トーションばね４７の第２ばね端部４７ｃは一対のフック端部４４ａ，４４ｂの間の隙間Ｓ２を介してフック端部４４ｂの外周に容易に装着可能となる。第２ばね端部４７ｃをフック端部４４ｂに装着した後に、一対のフック端部４４ａ，４４ｂの間の隙間Ｓ２が連結部４４ｄにより埋められる。これにより、トーションばね４７の第２ばね端部４７ｃが折れた場合でも、第２ばね端部４７ｃが隙間Ｓ２を通過することがより確実に抑制される。 (3) The lever member 43 is formed on the plate-shaped lever main body 43a and the edge of the lever main body 43a, and is arranged in the width direction W along the axial direction of the coil portion 47a, and the pair of side walls 43b facing each other. With 43c. The hook member 44 includes a pair of hook end portions 44a, 44b which are inserted into through holes 43h formed in the pair of side walls 43b, 43c and which are insertion portions facing each other between the pair of side walls 43b, 43c. One of the pair of hook ends 44a and 44b, the hook end 44b, is inserted into the ring-shaped second spring end 47c.
According to this configuration, even when the second spring end portion 47c of the torsion spring 47 is broken, the ring-shaped second spring end portion 47c is held on the outer periphery of the hook ends 44a and 44b.
Further, the pair of hook ends 44a and 44b face each other with a gap S2 larger than the wire diameter D of the torsion spring 47, and the hook member 44 connects the pair of hook ends 44a and 44b to each other. Be prepared.
According to this configuration, the second spring end portion 47c of the torsion spring 47 passes through the gap S2 between the pair of hook end portions 44a and 44b without elastically deforming the hook member 44 so that the gap S2 becomes large. It can be easily attached to the outer circumference of the hook end portion 44b. After the second spring end portion 47c is attached to the hook end portion 44b, the gap S2 between the pair of hook end portions 44a and 44b is filled with the connecting portion 44d. As a result, even if the second spring end portion 47c of the torsion spring 47 is broken, it is more reliably suppressed that the second spring end portion 47c passes through the gap S2.

（４）支持ピン４５はベース部材４１の上部に位置する。レバー部材４３は、コイル部４７ａの上部を囲む防護壁４３ｆを備える。防護壁４３ｆは、コイル部４７ａの軸方向に沿う幅方向Ｗにおいて、第１ばね端部４７ｂと第２ばね端部４７ｃの間であって、コイル部４７ａよりも小さいサイズで形成される。
この構成によれば、防護壁４３ｆにより、手指や工具等の異物がトーションばね４７に意図せず接触することが抑制される。また、防護壁４３ｆは、幅方向Ｗにおいて、コイル部４７ａよりも短いサイズに設定されている。このため、レバー部材４３が開かれる際、防護壁４３ｆが第１ばね端部４７ｂ及び第２ばね端部４７ｃに接触することを抑制する。 (4) The support pin 45 is located above the base member 41. The lever member 43 includes a protective wall 43f that surrounds the upper portion of the coil portion 47a. The protective wall 43f is formed between the first spring end portion 47b and the second spring end portion 47c in the width direction W along the axial direction of the coil portion 47a and having a size smaller than that of the coil portion 47a.
According to this configuration, the protective wall 43f prevents foreign substances such as fingers and tools from unintentionally contacting the torsion spring 47. Further, the protective wall 43f is set to a size shorter than that of the coil portion 47a in the width direction W. Therefore, when the lever member 43 is opened, the protective wall 43f is prevented from coming into contact with the first spring end portion 47b and the second spring end portion 47c.

In this case, the locked member 23 is provided on the outer peripheral surface of the container 10.

上記実施形態においては、ハンドル５０とパチン錠４０は、容器１０の外周面において異なる位置に設けられていたが、これに限らず、パチン錠４０は、コ字状のハンドル５０内の中央に位置していてもよい。 In the above embodiment, the handle 50 and the snap lock 40 are provided at different positions on the outer peripheral surface of the container 10, but the snap lock 40 is not limited to this and is located at the center of the U-shaped handle 50. You may be doing it.

上記実施形態においては、容器本体１１の外周面に２組の台座部材１５とパチン錠４０が設けられていたが、台座部材１５とパチン錠４０の数はこれに限定されない。例えば、３組の台座部材１５とパチン錠４０が容器本体１１の外周面に１２０度間隔で配置されてもよいし、４組の台座部材１５とパチン錠４０が容器本体１１の外周面に９０度間隔で配置されてもよい。 In the above embodiment, two sets of the pedestal member 15 and the snap lock 40 are provided on the outer peripheral surface of the container body 11, but the number of the pedestal member 15 and the snap lock 40 is not limited to this. For example, three sets of pedestal members 15 and a snap lock 40 may be arranged on the outer peripheral surface of the container body 11 at 120 degree intervals, or four sets of pedestal members 15 and a snap lock 40 may be arranged on the outer peripheral surface of the container body 11 at 90 degree intervals. It may be arranged at right angles.

上記実施形態においては、第２ばね端部４７ｃ内にはフック部材４４のフック端部４４ｂが挿通されていたが、これに限らず、レバー部材４３の一部である被挿通部が挿通されてもよい。 In the above embodiment, the hook end 44b of the hook member 44 is inserted into the second spring end 47c, but the present invention is not limited to this, and the inserted portion which is a part of the lever member 43 is inserted. May be good.

上記実施形態においては、トーションばね４７はリング状の第１ばね端部４７ｂ及び第２ばね端部４７ｃを備えていたが、第１ばね端部４７ｂ及び第２ばね端部４７ｃの何れか一方はリング状でなく、棒状に形成されてもよい。例えば、第２ばね端部４７ｃが棒状に形成された場合、レバー部材４３がベース部材４１に向けて閉じられるように、第２ばね端部４７ｃが常にフック端部４４ｂを押す。この棒状の第２ばね端部４７ｃがフック端部４４ｂを押している状態は、概念上、第２ばね端部４７ｃがフック端部４４ｂに連結した状態に含まれる。第１ばね端部４７ｂが棒状に形成された場合もこれと同様である。 In the above embodiment, the torsion spring 47 includes a ring-shaped first spring end portion 47b and a second spring end portion 47c, but any one of the first spring end portion 47b and the second spring end portion 47c is provided. It may be formed in a rod shape instead of a ring shape. For example, when the second spring end 47c is formed in a rod shape, the second spring end 47c always pushes the hook end 44b so that the lever member 43 is closed toward the base member 41. The state in which the rod-shaped second spring end portion 47c pushes the hook end portion 44b is conceptually included in the state in which the second spring end portion 47c is connected to the hook end portion 44b. The same applies when the first spring end portion 47b is formed in a rod shape.

上記実施形態においては、リング保持部４１ｄは抜け止め部４１ｇを備えていたが、抜け止め部４１ｇは省略されてもよい。
上記実施形態においては、バー部４１ｆの基端部４１ｉは、バー部４１ｆにおける基端部４１ｉ以外の部位よりも高さ方向Ｈの厚さが薄い薄肉部として形成されていたが、これに限らず、基端部４１ｉ以外の部位と同等の厚さに形成されてもよい。 In the above embodiment, the ring holding portion 41d includes the retaining portion 41g, but the retaining portion 41g may be omitted.
