Description

本発明は、例えばミニトマト等の野菜、果実等を収納包装することで店頭等に陳列販売する容器において、容器本体に開閉自在に設けた蓋体を容器本体に被せたとき、容器本体と蓋体とを確実に止着できるようにした食品包装容器に関する。 The present invention is a container for which vegetables such as cherry tomatoes, fruits, etc. are stored and packaged for display and sale at stores, and when the container body is covered with a lid that can be opened and closed, the container body and the lid are covered. It relates to a food packaging container that can be securely attached to the body.

従来から、店頭において例えばミニトマト等の小粒・小型の野菜、果物等を販売するとき、これらを透明容器に収納し陳列しており、この透明容器自体は、適当な容量を有する容器本体とこれに被せられる蓋体とから成っている。そして、容器本体に蓋体をしっかりと止着できるように、例えば容器本体、蓋体それぞれに形成されているフランジ状の周縁に、相互に嵌合される凸部と凹部とから成るボタン嵌合構成が採用されている。 Conventionally, when selling small or small vegetables such as cherry tomatoes, fruits, etc. at stores, these are stored and displayed in a transparent container, and the transparent container itself is a container body having an appropriate capacity and this. It consists of a lid that can be put on. Then, in order to firmly fasten the lid to the container body, for example, a button fitting composed of convex portions and concave portions that are mutually fitted to the flange-shaped peripheral edges formed on the container body and the lid body, respectively. The configuration is adopted.

例えば特許文献１に示される包装用容器であり、特許文献２に示される薄肉合成樹脂製の包装容器であり、特許文献３に示される凹凸嵌合容器である。特許文献１の包装容器は凹部に嵌まる凸部において、外側へ張り出す外周の少なくとも一部に、直線状に形成されていて凹部への進入に際し凹部の口にあたる当接部を備えているとする。特許文献２の包装容器は、複数の突起を膨出させた略円筒状の突出部を形成した嵌合凸部と、開口周囲に内向きに膨出させた突条を形成した嵌合凹部とから成り、突出部と突条とを係合させて嵌合凹部内に嵌合凸部を嵌合するとする。特許文献３の凹凸嵌合容器は、開口縁部が略正方形状の凹部内に、傾斜面の最大径部が開口縁部の内接円以下に形成した円筒状の凸部を嵌合したとき、その最大径部が凹部を押し広げて係合させるとする。 For example, it is a packaging container shown in Patent Document 1, a packaging container made of a thin-walled synthetic resin shown in Patent Document 2, and an uneven fitting container shown in Patent Document 3. The packaging container of Patent Document 1 has a convex portion that fits into the concave portion, and has a contact portion that is formed in a straight line and corresponds to the mouth of the concave portion when entering the concave portion, at least a part of the outer peripheral portion that projects outward. do. The packaging container of Patent Document 2 includes a fitting convex portion having a substantially cylindrical protrusion formed by bulging a plurality of protrusions and a fitting concave portion having a ridge formed inwardly bulging around the opening. It is assumed that the protruding portion and the ridge are engaged with each other to fit the fitting convex portion in the fitting concave portion. The concave-convex fitting container of Patent Document 3 has a concave portion having a substantially square opening edge and a cylindrical convex portion having a maximum diameter of an inclined surface formed below the inscribed circle of the opening edge. , It is assumed that the maximum diameter portion expands and engages the concave portion.

ところが、特許文献１による嵌合構成は、嵌合する際の凸部の凹部内への進入の滑りをよくするとしても、嵌合状態は確実ではなく、特許文献２による嵌合構成は、嵌合凹部の突条を嵌合凸部の突出部を乗り越えさせるとするから、嵌合時には乗り越えさせるよう大きな変形力を加える必要がある。特許文献３による嵌合構成は、凸部の最大径部によって凹部の周壁を押し広げるとするから、押し広げて留まる部位以外も押し広げてしまうよう塑性変形が生じ、嵌合後で外れることもあった。 However, in the fitting configuration according to Patent Document 1, the fitting state is not certain even if the sliding of the protrusion into the concave portion at the time of fitting is improved, and the fitting configuration according to Patent Document 2 is fitted. Since it is assumed that the ridges of the joint recesses get over the protruding portions of the fitting protrusions, it is necessary to apply a large deformation force so as to get over the protrusions at the time of fitting. In the fitting configuration according to Patent Document 3, since the peripheral wall of the concave portion is expanded by the maximum diameter portion of the convex portion, plastic deformation occurs so as to expand the portion other than the portion where the concave portion is expanded and stays, and the fitting configuration may be disengaged after fitting. there were.

At that time, the uneven portion in the circumferential direction to be engaged and engaged inside and outside along the fitting direction of the fitting convex portion and the fitting concave portion is divided by a plurality of groove-shaped portions along the fitting direction and left behind. One of the inner and outer uneven parts is positioned and guided in the other groove-shaped part, and the parts of the uneven parts existing on both sides of the groove-shaped part are engaged with each other, so that the fitting convex part and the fitting concave part are mutually engaged.

本発明は以上説明したように構成されているため、容器本体１に蓋体１１を被せるとき、嵌合手段２０におけるボタン構造状の嵌合凸部３１、嵌合凹部４１相互の嵌合によって容器本体１に蓋体１１を確実に止着嵌合できる。 Since the present invention is configured as described above, when the lid 11 is put on the container body 1, the container is fitted by fitting the button-shaped fitting convex portion 31 and the fitting concave portion 41 in the fitting means 20 to each other. The lid 11 can be securely fastened and fitted to the main body 1.

しかも、嵌合凸部３１、嵌合凹部４１の相互の嵌合時では、嵌合凸部３１の凸部側突起部３６が嵌合凹部４１の凹部側突出部４７内に嵌まり込み、嵌合方向で案内されて、残置されている凸部側突出部３５の隅部分が凹部側突出部４７を強制的に押し広げるように係止する。同様に、嵌合凹部４１の凹部側凹み部４６が嵌合凸部３１の凸部側窪み部３７内に嵌まり込み、残置されている凹部側窪み部４５の隅部分が凸部側窪み部３７を強制的に押し広げるように係止する。こうすることで、凸部側窪み部３７、凹部側突出部４７それぞれの分断部位の脇部における凸部側突出部３５と凹部側窪み部４５との相互間で乗り越えた嵌合方向に沿う係合によって嵌合凸部３１、嵌合凹部４１の嵌合状態を一層強固にし、嵌合凸部３１は嵌合凹部４１内に止められ、嵌合状態を維持することができる。 Moreover, when the fitting convex portion 31 and the fitting concave portion 41 are mutually fitted, the convex portion side protrusion 36 of the fitting convex portion 31 is fitted into the concave portion side protrusion 47 of the fitting concave portion 41 and fitted. Guided in the directional direction, the remaining corner portion of the convex portion side protrusion 35 is locked so as to forcibly expand the concave portion side protrusion 47. Similarly, the concave portion 46 of the fitting concave portion 41 is fitted into the convex side concave portion 37 of the fitting convex portion 31, and the corner portion of the remaining concave portion side concave portion 45 is the convex side concave portion. The 37 is locked so as to be forcibly expanded. By doing so, the protrusions 35 on the convex side and the concave portion 45 on the concave side are engaged along the fitting direction overcoming each other at the side portions of the divided portions of the concave portion 37 on the convex side and the protruding portion 47 on the concave side. By combining, the fitting state of the fitting convex portion 31 and the fitting concave portion 41 is further strengthened, and the fitting convex portion 31 is stopped in the fitting concave portion 41, and the fitting state can be maintained.

また、凸部側突出部３５と凹部側窪み部４５との相互間の乗り越える係合は、凸部側突出部３５と凹部側窪み部４５とはともに周方向で分断されていることで、大きな作用力を要せずに係合させることができる。 Further, the overcoming engagement between the convex portion side protruding portion 35 and the concave portion side recessed portion 45 is large because both the convex portion side protruding portion 35 and the concave portion side recessed portion 45 are separated in the circumferential direction. It can be engaged without requiring any acting force.

すなわち、嵌合凸部３１、嵌合凹部４１相互の嵌合に際し、凸部側突出部３５と凹部側窪み部４５とはそれぞれの周方向に沿う全域での乗り越えではなく、凸部側窪み部３７、凹部側突出部４７それぞれで分断されていて、凸部側突出部３５は凸部側突起部３６と共に凹部側突出部４７内に、凹部側窪み部４５は凹部側凹み部４６と共に凸部側窪み部３７内に案内されるから、嵌合方向に沿って円滑に進入される。また、進入後では、凸部側窪み部３７、凹部側突出部４７それぞれの脇部における凸部側突出部３５、凹部側窪み部４５相互を部分的に噛み合い、係合させるのであり、これらの噛み合い、係合箇所は周方向で複数であることと相俟って、容易には解除されず、嵌合凸部３１、嵌合凹部４１両者の嵌合状態を安定的に維持させることができる。 That is, when the fitting convex portion 31 and the fitting concave portion 41 are fitted to each other, the convex portion side protruding portion 35 and the concave portion side concave portion 45 do not get over the entire area along the respective circumferential directions, but the convex portion side concave portion. 37, the concave portion side protrusion 47 is divided by each, the convex side protrusion 35 is in the concave side protrusion 47 together with the convex side protrusion 36, and the concave side concave portion 45 is a convex portion together with the concave side concave portion 46. Since it is guided into the side recess 37, it smoothly enters along the fitting direction. Further, after entering, the convex portion side protruding portion 37, the convex portion side protruding portion 35, and the concave portion side concave portion 45 on the side portions of the convex portion side recessed portion 37 and the concave portion side protruding portion 47 are partially meshed with each other and engaged with each other. Coupled with the fact that there are a plurality of meshing and engaging points in the circumferential direction, it is not easily disengaged, and the fitting state of both the fitting convex portion 31 and the fitting concave portion 41 can be stably maintained. ..

以下、図面を参照して本発明を実施するための一形態を説明すると、図において示される符号１は例えばミニトマト等の比較的に小粒・小型の野菜、果実等の収納物Ｔを収納保持できるようにしたほぼボックス状の容器本体である。図示例にあっては、この容器本体１には、容器本体１の開口部を閉塞するように被せられる蓋体１１がヒンジ部１０を介して揺動自在にして一体状に連結されている。また、図示を省略したが、容器本体１と蓋体１１とが分離されている場合も同様に実施可能である。 Hereinafter, to explain one embodiment for carrying out the present invention with reference to the drawings, reference numeral 1 shown in the drawings stores and holds a container T such as relatively small and small vegetables such as cherry tomatoes and fruits. It is an almost box-shaped container body that can be made. In the illustrated example, a lid 11 covered with the container body 1 so as to close the opening of the container body 1 is swingably connected to the container body 1 via a hinge portion 10. Further, although not shown, the same can be performed when the container body 1 and the lid 11 are separated.

図１に示すように、容器本体１の周縁には縁状になっている本体フランジ２が突出状に形成されており、また蓋体１１の周縁にも同様に縁状になっている蓋体フランジ１２が突出状に形成されており、これらの本体フランジ２、蓋体フランジ１２は蓋体１１による容器本体１の閉塞時には互いに当接ないし近接して相対向されるようになっている。 As shown in FIG. 1, a main body flange 2 having a rim shape is formed in a protruding shape on the peripheral edge of the container main body 1, and a lid body having a rim shape is also formed on the peripheral edge of the lid body 11. The flange 12 is formed in a protruding shape, and the main body flange 2 and the lid flange 12 are in contact with each other or face each other in close proximity to each other when the container main body 1 is closed by the lid 11.

そして、この本体フランジ２、蓋体フランジ１２相互間には、嵌合凸部３１と、この嵌合凸部３１が内部に嵌合止着される嵌合凹部４１とから成るボタン構造の嵌合手段２０によって、蓋体１１は容器本体1の開口を閉塞し、結合させる。 Then, between the main body flange 2 and the lid flange 12, a button structure including a fitting convex portion 31 and a fitting concave portion 41 to which the fitting convex portion 31 is fitted and fastened internally is fitted. By means 20, the lid 11 closes and connects the opening of the container body 1.

この嵌合手段２０は、図示のように容器本体１に対して蓋体１１が揺動自在に一体状に連結されている場合では、ヒンジ部１０部位とは遠隔部位に相当する開放端側に適当数で、例えば両脇部位に対状にして配置されており、必要があればヒンジ部１０側にも配置される。また、容器本体１と蓋体１１とが分離した別体に構成されている場合には、これらの開口縁の周縁に適当数で相対させて配置される。 When the lid 11 is swingably and integrally connected to the container body 1 as shown in the figure, the fitting means 20 is located on the open end side corresponding to the remote portion from the hinge portion 10 portion. An appropriate number of them are arranged in pairs, for example, on both side portions, and if necessary, they are also arranged on the hinge portion 10 side. When the container body 1 and the lid 11 are separated from each other, they are arranged so as to face each other in an appropriate number on the peripheral edge of the opening edge.

嵌合手段２０は、相互に嵌合されるよう、嵌合凸部３１とこの嵌合凸部３１が内部に強制的に進入して嵌合する嵌合凹部４１とから成り、図例のように、嵌合凸部３１は蓋体１１の蓋体フランジ１２の片面に対し容器本体１側に向かって突出状となして、蓋体１１の開口側に出張るように形成され、嵌合凹部４１は容器本体１の本体フランジ２の片面に対し窪み状となして、容器本体１の底部側に向かって出張るように形成される。もとより、これらの嵌合凸部３１、嵌合凹部４１それぞれは、容器本体１に蓋体１１が被せられたときに合致する位置に配置形成されている。尚、容器本体１に嵌合凸部３１が、蓋体１１に嵌合凹部４１が配置形成される場合もあり、この場合には、容器本体１の開口側に出張るように、また蓋体１１の天板側に出張るように形成される。 The fitting means 20 is composed of a fitting convex portion 31 and a fitting concave portion 41 in which the fitting convex portion 31 forcibly enters and fits into the inside so as to be fitted to each other, as shown in the figure. In addition, the fitting convex portion 31 is formed so as to project toward the container body 1 side with respect to one side of the lid flange 12 of the lid 11 so as to travel toward the opening side of the lid 11, and the fitting concave portion 31 is formed. The 41 is formed in a recessed shape with respect to one side of the main body flange 2 of the container main body 1 so as to travel toward the bottom side of the container main body 1. Of course, each of these fitting protrusions 31 and fitting recesses 41 is arranged and formed at positions that match when the lid 11 is put on the container body 1. In some cases, the fitting convex portion 31 is arranged on the container main body 1 and the fitting concave portion 41 is arranged on the lid body 11. In this case, the fitting convex portion 31 is arranged and formed on the opening side of the container main body 1 so as to travel to the opening side of the container main body 1 and the lid body. It is formed so as to travel to the top plate side of 11.

図２に示すように、嵌合凸部３１は、嵌合凸部３１自体の頂部の側壁部には、頂部から基部に至るに伴い次第に大径となるよう広がっている頂部傾斜面３２が形成されている。本体フランジ２に連続する、嵌合凸部３１の開口部には、この開口端側から次第に小径となるよう嵌合凸部３１の内方に窄まっている基部傾斜面３４が形成されている。 As shown in FIG. 2, the fitting convex portion 31 has a top inclined surface 32 formed on the side wall portion of the top of the fitting convex portion 31 itself so as to gradually increase in diameter from the top to the base. Has been done. A base inclined surface 34 that is narrowed inward of the fitting convex portion 31 is formed in the opening of the fitting convex portion 31 that is continuous with the main body flange 2 so that the diameter gradually decreases from the opening end side. ..

一方、図３に示すように、嵌合凹部４１は、嵌合凸部３１が嵌合されるよう平面から見た外形を同様に形成してあり、奥底部の側壁部には、嵌合凸部３１が嵌合凹部４１に嵌合したとき、前記頂部傾斜面３２が当接する底部傾斜面４２が形成されている（図７における各端面図参照）。本体フランジ２に連続する、嵌合凹部４１の開口部の側壁部には、前記基部傾斜面３４が当接されるよう、開口部に至るに伴い次第に外方広がり状となる開口傾斜面４３が形成されている。 On the other hand, as shown in FIG. 3, the fitting concave portion 41 has the same outer shape as seen from a plane so that the fitting convex portion 31 is fitted, and the fitting convex portion is formed on the side wall portion of the deep bottom portion. When the portion 31 is fitted into the fitting recess 41, a bottom inclined surface 42 with which the top inclined surface 32 abuts is formed (see each end view in FIG. 7). An opening inclined surface 43 that gradually expands outward as it reaches the opening is provided on the side wall of the opening of the fitting recess 41 that is continuous with the main body flange 2 so that the base inclined surface 34 is in contact with the side wall. It is formed.

また、嵌合凸部３１の頂部傾斜面３２、嵌合凹部４１の開口傾斜面４３それぞれは、同一の傾斜角度で形成されていることで、嵌合凸部３１の嵌合凹部４１内への嵌合開始時では、嵌合凸部３１、嵌合凹部４１相互間のズレを軽減でき、嵌合操作が容易になるように配慮してある（図８参照）。 Further, since the top inclined surface 32 of the fitting convex portion 31 and the opening inclined surface 43 of the fitting concave portion 41 are formed at the same inclination angle, the fitting convex portion 31 can be inserted into the fitting concave portion 41. At the start of fitting, it is possible to reduce the deviation between the fitting convex portion 31 and the fitting concave portion 41, and consideration is given to facilitating the fitting operation (see FIG. 8).

嵌合凸部３１における前記頂部傾斜面３２は、嵌合凸部３１自体の側壁部が外方に広がるように断面でほぼ山形状に膨出させられて周方向に沿って突条となっている凸部側突出部３５を形成している。この凸部側突出部３５では、嵌合凸部３１の基部側に至るに伴い嵌合凸部３１の内方に次第に窄まり状となる傾斜面を有し、この傾斜面は嵌合凸部３１の筒状の側壁部３８を介して前記基部傾斜面３４に繋がっている（図２（Ｂ）参照）。 The top inclined surface 32 in the fitting convex portion 31 is bulged in a substantially mountain shape in a cross section so that the side wall portion of the fitting convex portion 31 itself spreads outward, and becomes a protrusion along the circumferential direction. The convex portion side protruding portion 35 is formed. The convex portion side protruding portion 35 has an inclined surface that gradually becomes narrowed inward of the fitting convex portion 31 as it reaches the base side of the fitting convex portion 31, and this inclined surface is the fitting convex portion. It is connected to the base inclined surface 34 via the cylindrical side wall portion 38 of 31 (see FIG. 2B).

嵌合凹部４１における前記開口傾斜面４３は、嵌合凹部４１自体の側壁部に内方に窄まるように断面でほぼ山形状に窪ませられて周方向に沿って溝状となっている凹部側窪み部４５を形成している。この凹部側窪み部４５では、嵌合凹部４１の底部側に至るに伴い嵌合凹部４１の外方に次第に広がり状となる傾斜面を有し、この傾斜面は嵌合凹部４１の筒状の側壁部４４を介して前記底部傾斜面４２に繋がっている（図３（Ｃ）参照）。 The opening inclined surface 43 in the fitting recess 41 is recessed in a substantially mountain shape in cross section so as to be narrowed inward in the side wall portion of the fitting recess 41 itself, and has a groove shape along the circumferential direction. A side recess 45 is formed. The recessed portion 45 has an inclined surface that gradually expands outward of the fitting recess 41 as it reaches the bottom side of the fitting recess 41, and this inclined surface has a cylindrical shape of the fitting recess 41. It is connected to the bottom inclined surface 42 via the side wall portion 44 (see FIG. 3C).

凸部側突出部３５は、後述する嵌合方向に沿って形成された複数の凸部側窪み部３７によって分断されており、分断されたことによる残置部分は、嵌合凸部３１の外方に向かって突出状となっている原形のままである。同様に、凹部側窪み部４５は、後述する嵌合方向に沿って形成された複数の凹部側突出部４７によって分断されており、分断されたことによる残置部分は、嵌合凹部４１の内方に向かって窪み状となっている原形のままである。また、嵌合凸部３１における凸部側突出部３５の残置部分は、後述する嵌合凹部４１における凹部側突出部４７と、嵌合凹部４１における凹部側窪み部４５の残置部分は、後述する嵌合凸部３１における凸部側窪み部３７と、内外方向で互いに向かい合うような位置で設けられる。 The convex portion side protruding portion 35 is divided by a plurality of convex portion side recessed portions 37 formed along the fitting direction described later, and the remaining portion due to the division is the outer side of the fitting convex portion 31. It remains in its original shape, which is protruding toward. Similarly, the recessed portion 45 is divided by a plurality of recessed side protrusions 47 formed along the fitting direction described later, and the remaining portion due to the division is inside the fitting recess 41. It remains in its original shape, which is dented toward. Further, the remaining portion of the convex side protruding portion 35 in the fitting convex portion 31 is the recessed side protruding portion 47 in the fitting recess 41 described later, and the remaining portion of the concave portion side recessed portion 45 in the fitting recess 41 will be described later. It is provided at a position facing each other in the inward and outward directions with the concave portion 37 on the convex portion side of the fitting convex portion 31.

これらの凸部側突出部３５と凹部側窪み部４５とは、嵌合凸部３１が嵌合凹部４１内に進入したとき互いに乗り越えて噛み合うようになっており（図８参照）、凸部側突出部３５の傾斜面と凹部側窪み部４５の傾斜面とが互いにほぼ当接状となって、嵌合凸部３１を嵌合凹部４１内に止めるようにしている（図７におけるＦ－Ｆ線端面図参照）。 When the fitting convex portion 31 enters the fitting concave portion 41, the convex portion side protruding portion 35 and the concave portion side concave portion 45 get over each other and mesh with each other (see FIG. 8), and the convex portion side. The inclined surface of the protruding portion 35 and the inclined surface of the concave portion 45 are substantially in contact with each other so that the fitting convex portion 31 is stopped in the fitting concave portion 41 (FF in FIG. 7). See line end view).

また、換言すれば、嵌合凸部３１の側壁部には、外方に突出状に嵌合方向に沿って張り出した複数の凸部側突起部３６が、この嵌合凸部３１の中央位置を中心とする仮想円上に沿って所定間隔毎に配列形成されていることで断続的な凸部側突出部３５を形成している。この凸部側突起部３６内に前記凸部側突出部３５が、いわば、残置されているようになり、図２に示すように平面から見て突出部の先端である突出端は、凸部側突出部３５の最大径部縁であって、仮想円の円周に沿う円弧状を呈し、隣接する凸部側突起部３６相互間は、この凸部側突起部３６自体の隣接する両脇の側壁部分によって、嵌合凸部３１の内方に向かって窪むような弓形円弧状の凸部側窪み部３７となっている。 Further, in other words, on the side wall portion of the fitting convex portion 31, a plurality of convex portion side protrusions 36 projecting outward in a protruding shape along the fitting direction are located at the center position of the fitting convex portion 31. The protrusions 35 on the convex side are formed intermittently by being arranged at predetermined intervals along the virtual circle centered on the above. The convex side protruding portion 35 is left behind in the convex side protruding portion 36, and as shown in FIG. 2, the protruding end which is the tip of the protruding portion when viewed from a plane is a convex portion. It is the maximum diameter edge of the side protrusion 35 and has an arc shape along the circumference of the virtual circle. By the side wall portion of the above, the concave portion 37 having an arcuate arcuate shape is formed so as to be recessed inward of the fitting convex portion 31.

そして、この凸部側窪み部３７は、嵌合凸部３１における前記頂部傾斜面３２の頂部部位から前記基部傾斜面３４部位に至るまでの嵌合方向に沿う溝状になっていることで、嵌合凸部３１自体の側壁の周方向に沿って形成してある前記凸部側突出部３５を断続的に分断すると共に、いわば凸部側突起部３６内で残置された凸部側突出部３５部分は嵌合凸部３１の外方に向かって出張っている状態の原形のままを呈している。また、この凸部側突出部３５の残置部分は、嵌合凹部４１における凹部側突出部４７と向かい合うように位置決めして配置されている。 The convex portion side recessed portion 37 has a groove shape along the fitting direction from the top portion of the top inclined surface 32 in the fitting convex portion 31 to the base inclined surface 34 portion. The convex side protruding portion 35 formed along the circumferential direction of the side wall of the fitting convex portion 31 itself is intermittently divided, and the convex side protruding portion left in the convex side protruding portion 36, so to speak. The 35 portion shows the original shape of the fitting convex portion 31 in a state of traveling toward the outside. Further, the remaining portion of the convex portion side protruding portion 35 is positioned and arranged so as to face the concave portion side protruding portion 47 in the fitting recess 41.

一方、嵌合凹部４１の側壁部には、嵌合凹部４１自体の内方に嵌合方向に沿って窪むようにした複数の凹部側凹み部４６が、嵌合凹部４１の中央位置を中心として、嵌合凸部３１における仮想円と同様な仮想円上に沿って所定間隔毎に配列形成されていることで、断続的な凹部側窪み部４５を形成している。この凹部側凹み部４６は、図３に示すように平面から見て凹み部の奥端は、前記凹部側窪み部４５の最小径部縁であって、仮想円の円周に沿う円弧状を呈し、隣接する凹部側凹み部４６相互間は、この凹部側凹み部４６自体の隣接する両脇の側壁部分によって、嵌合凹部４１の外方に向かって突出するような弓形円弧状の凹部側突出部４７となっている。すなわち、凹部側突出部４７は、嵌合凹部４１自体の側壁部に、外方に向かって突出するようにして、嵌合凹部４１の中央位置を中心とする仮想円上に沿って所定間隔毎に配列形成されていることになる。 On the other hand, on the side wall portion of the fitting recess 41, a plurality of recess-side recesses 46 that are recessed inward of the fitting recess 41 itself along the fitting direction are provided around the center position of the fitting recess 41. By forming an array at predetermined intervals along a virtual circle similar to the virtual circle in the fitting convex portion 31, an intermittent concave portion side recessed portion 45 is formed. As shown in FIG. 3, the recessed portion 46 has an arc shape along the circumference of the virtual circle, with the inner end of the recessed portion being the minimum diameter edge of the recessed portion 45 when viewed from a plane. The concave side of the arcuate shape is such that the adjacent concave portions 46 are projected outward from the fitting concave portion 41 by the side wall portions on both sides of the concave concave portion 46 itself. It is a protruding portion 47. That is, the recess-side protruding portion 47 projects outward from the side wall portion of the fitting recess 41 itself at predetermined intervals along a virtual circle centered on the center position of the fitting recess 41. It will be arranged in.

そして、凹部側突出部４７は、開口傾斜面４３の開口端から底部傾斜面４２の開口側端に至るまでに形成されている。また、凹部側突出部４７は、開口傾斜面４３の外縁側の開口端から底部傾斜面４２の開口側端に至るまでの嵌合方向に沿う溝状になっていることで、嵌合凹部４１自体の側壁の周方向に沿って形成してある前記凹部側窪み部４５を断続的に分断すると共に、凹部側凹み部４６内で残置された凹部側窪み部４５部分は嵌合凹部４１の内方に向かって出張っている状態の原形のままを呈している。また、この凹部側窪み部４５の残置部分は、嵌合凸部３１における凸部側窪み部３７と向かい合うように位置決めして配置されている。 The concave portion side protrusion 47 is formed from the opening end of the opening inclined surface 43 to the opening side end of the bottom inclined surface 42. Further, the concave portion side protrusion 47 has a groove shape along the fitting direction from the opening end on the outer edge side of the opening inclined surface 43 to the opening side end of the bottom inclined surface 42, so that the fitting concave portion 41 is formed. The recess-side recess 45 formed along the circumferential direction of the side wall of itself is intermittently divided, and the recess-side recess 45 left in the recess-side recess 46 is inside the fitting recess 41. It is in its original form as it is on a business trip toward the direction. Further, the remaining portion of the recessed portion 45 is positioned and arranged so as to face the convex portion side recessed portion 37 in the fitting convex portion 31.

尚、図例にあっては、嵌合凸部３１、嵌合凹部４１はともに平面から見て円形状に形成されているも、これに限定されることはなく、また凸部側突起部３６、凹部側凹み部４６、凹部側突出部４７は相互に同数にして仮想円上に等間隔で例えば４５度間隔で計８個にして配列形成されるも、これに限定されない。 In the illustrated example, both the fitting convex portion 31 and the fitting concave portion 41 are formed in a circular shape when viewed from a plane, but the present invention is not limited to this, and the convex portion side protrusion portion 36 is not limited thereto. The recessed portions 46 and the recessed protrusions 47 are arranged in the same number on the virtual circle at equal intervals, for example, at intervals of 45 degrees, for a total of eight, but the present invention is not limited to this.

嵌合凸部３１が嵌合凹部４１内に進入し相互に嵌合されるとき、図４に示すように、凸部側突起部３６は、嵌合凹部４１における隣接する凹部側凹み部４６相互間の凹部側突出部４７内に案内されて位置されるよう、凸部側突起部３６の中心線と凹部側突出部４７の中心線とが合致するようにしてある。と共に、凸部側突起部３６の両脇外側面である凸部側突出部３５の隅部分は、凹部側突出部４７の両脇内側面と当接し、凸部側突起部３６が凹部側突出部４７を半ば押し広げるように係止するようになっている。 When the fitting convex portion 31 enters the fitting concave portion 41 and is fitted to each other, as shown in FIG. 4, the convex portion side protrusion portion 36 is a mutual concave portion side concave portion 46 in the fitting concave portion 41. The center line of the convex portion side protrusion 36 and the center line of the concave portion side protrusion 47 are aligned so as to be guided and positioned in the concave portion side protrusion 47 between them. At the same time, the corner portion of the convex side protrusion 35, which is the outer surface on both sides of the convex side protrusion 36, abuts on the inner side surfaces on both sides of the concave side protrusion 47, and the convex side protrusion 36 protrudes on the concave side. The portion 47 is designed to be locked so as to be pushed out halfway.

また、嵌合凸部３１における凸部側窪み部３７と、嵌合凹部４１における凹部側凹み部４６とは、嵌合凸部３１が嵌合凹部４１内に進入、嵌合されるとき、凸部側窪み部３７内に凹部側凹み部４６が案内されるように位置決めされるよう、凹部側凹み部４６と凸部側窪み部３７とのそれぞれの中心線は合致するようにされている。このように、合致された嵌まり込みは、凸部側突起部３６、凹部側突出部４７相互の嵌まり込みと共に、嵌合凸部３１、嵌合凹部４１相互を周方向で位置ずれを生じさせることなく、確実、円滑に嵌合させるようにしている。 Further, the convex side recessed portion 37 in the fitting convex portion 31 and the concave portion side concave portion 46 in the fitting concave portion 41 are convex when the fitting convex portion 31 enters and is fitted into the fitting concave portion 41. The center lines of the recessed portion 46 and the convex recessed portion 37 are aligned with each other so that the recessed portion 46 is positioned so as to be guided in the recessed portion 37. In this way, the fitted fitting causes the fitting convex portion 31 and the fitting recess 41 to be displaced in the circumferential direction together with the fitting of the convex side protrusion 36 and the concave side protrusion 47. It is designed to fit securely and smoothly without causing it.

このとき、図例のように、凸部側突起部３６の両脇部分である凸部側突出部３５の隅部分、凹部側凹み部４６の両脇部分である凹部側窪み部４５の隅部分それぞれを平面から見て鈍角状に形成しておき、凹部側突出部４７、凸部側窪み部３７それぞれの内側面を円弧状に形成しておき、鈍角状の隅部分が円弧状の側面をやや広げるように強制的に係止するようにすることで、嵌合凸部３１と嵌合凹部４１とが一層強固な止着状態とすることができる（図４参照）。 At this time, as shown in the figure, the corner portion of the convex portion side protruding portion 35 which is both side portions of the convex portion side protruding portion 36 and the corner portion of the concave portion side recessed portion 45 which is both side portions of the concave portion side concave portion 46. Each is formed in an obtuse angle when viewed from a plane, the inner side surface of each of the concave portion side protrusion 47 and the convex portion side concave portion 37 is formed in an arc shape, and the obtuse angle corner portion forms an arc shape side surface. By forcibly locking the fitting convex portion 31 and the fitting concave portion 41 so as to be slightly widened, the fitting convex portion 31 and the fitting concave portion 41 can be in a more firmly fixed state (see FIG. 4).

また、図例のように、凸部側突起部３６内における平面から見た凸部側突出部３５の最大幅員部分は、凹部側突出部４７における内側面に当接する部位においての平面から見た凹部側窪み部４５の内法幅員に比しやや大きくされている。同様に、凹部側凹み部４６内における平面から見た凹部側窪み部４５の最大幅員部分は、凸部側窪み部３７の内法幅員に比し大きくされている。こうすることで、嵌合凸部３１が嵌合凹部４１内に進入するとき、凸部側突起部３６、凹部側突出部４７それぞれの両脇部位では、前記凸部側突出部３５と凹部側窪み部４５とが互いに乗り越えて嵌合方向に沿って噛み合うようになっている。 Further, as shown in the figure, the maximum width portion of the convex portion side protrusion 35 seen from the plane in the convex side protrusion 36 is seen from the plane at the portion of the concave protrusion 47 that abuts on the inner side surface. It is slightly larger than the inner width of the recess 45 on the recess side. Similarly, the maximum width portion of the concave portion side recessed portion 45 seen from the plane in the concave portion side recessed portion 46 is made larger than the inner width portion of the convex portion side recessed portion 37. By doing so, when the fitting convex portion 31 enters the fitting concave portion 41, the convex portion side protruding portion 35 and the concave portion side are provided at both side portions of the convex portion side protruding portion 36 and the concave portion side protruding portion 47, respectively. The recessed portions 45 get over each other and mesh with each other along the fitting direction.

次に容器本体１に所定の収納物Ｔを収納後、蓋体１１を被せて閉塞する場合の嵌合手段２０による嵌合状態を説明する。容器本体１の嵌合凸部３１に蓋体１１の嵌合凹部４１を位置決めして押し当てる嵌合手段２０によって強制的にでも嵌合させる。 Next, a fitting state by the fitting means 20 when the predetermined stored object T is stored in the container main body 1 and then the lid 11 is covered and closed will be described. The fitting recess 41 of the lid 11 is positioned and pressed against the fitting convex portion 31 of the container body 1 to be forcibly fitted by the fitting means 20.

押し当てるとき、嵌合凸部３１における残置されていた凸部側突出部３５は、凸部側突起部３６と共に嵌合凹部４１における凹部側突出部４７内に位置決めされて案内されるように進入し、凹部側突出部４７を押し広げるようにして嵌合係止する。同様に、嵌合凹部４１における残置されていた凹部側窪み部４５は、凹部側凹み部４６と共に嵌合凸部３１における凸部側窪み部３７内に位置決め案内されるように進入し、凸部側窪み部３７を押し広げるように嵌合係止する。 At the time of pressing, the convex portion side protrusion 35 left in the fitting convex portion 31 enters so as to be positioned and guided in the concave portion side protrusion 47 in the fitting concave portion 41 together with the convex side protrusion 36. Then, the concave portion side protrusion 47 is pushed open to engage and lock. Similarly, the recess-side recess 45 left in the fitting recess 41 enters the recess-side recess 37 together with the recess-side recess 46 so as to be positioned and guided into the convex-side recess 37 in the fitting convex 31. The side recess 37 is fitted and locked so as to be pushed open.

これに伴い、嵌合凸部３１における周状の断続的配置の凸部側突出部３５と、嵌合凹部４１における周状の断続的配置の凹部側窪み部４５とは、凸部側突起部３６、凹部側突出部４７それぞれの脇部において部分的に互いに乗り越えて噛み合って係合する。 Along with this, the convex side protruding portion 35 having the circumferentially intermittent arrangement in the fitting convex portion 31 and the concave side concave portion 45 having the circumferentially intermittently arranged concave portion in the fitting concave portion 41 have the convex side protruding portion. 36, the side portions of the concave portion side protrusions 47 partially get over each other and mesh with each other to engage with each other.

このように、凸部側突起部３６と凹部側突出部４７との、また凹部側凹み部４６と凸部側窪み部３７とのそれぞれの径方向に沿った強制的な押し広げ状の係止、及び凸部側突出部３５と凹部側窪み部４５との嵌合方向での部分的な噛み合いによって嵌合凸部３１は嵌合凹部４１内に嵌合係止し、蓋体１１は容器本体１に確実に被せられ、容器本体１を閉塞する。 In this way, the convex side protrusion 36 and the concave side protrusion 47, and the concave side concave portion 46 and the convex side concave portion 37 are forcibly expanded and locked along the respective radial directions. , And the fitting convex portion 31 is fitted and locked in the fitting concave portion 41 by partial engagement in the fitting direction between the convex portion side protruding portion 35 and the concave portion side concave portion 45, and the lid 11 is the container body. It is surely covered with 1 and closes the container body 1.

そして、容器本体１から蓋体１１を開放するには、嵌合手段２０位置の本体フランジ２、蓋体フランジ１２を互いに離反するようにすることで、嵌合凸部３１を嵌合凹部４１から強制的に抜き出せばよい。 Then, in order to open the lid 11 from the container main body 1, the fitting convex portion 31 is separated from the fitting concave portion 41 by separating the main body flange 2 and the lid flange 12 at the fitting means 20 position from each other. You can forcibly pull it out.
