従来、この種の容器としては、例えば、合成樹脂シート製の容器本体の開口部に、合成樹脂シート製の蓋体を脱着開閉可能に取り付けるように構成したものが知られている。このような容器では、容器本体内に惣菜等の収容物を収容して、容器本体の開口部に蓋体を被覆装着したとき、蓋体を閉鎖位置に密封状態で確実に止着する必要がある。このため、この種の容器においては、容器本体の開口周縁にフランジ部が形成されるとともに、蓋体の外周縁に嵌合部が形成され、容器本体に対する蓋体の閉鎖状態で、嵌合部がフランジ部に外嵌されるようになっている。   2. Description of the Related Art Conventionally, as this type of container, for example, a container configured so that a lid made of a synthetic resin sheet is attached to an opening of a synthetic resin sheet container main body so as to be detachable can be opened and closed. In such a container, it is necessary to securely fasten the lid body in a sealed state in a closed position when the container body contains a container such as side dish and the lid body is covered and attached to the opening of the container body. is there. For this reason, in this type of container, a flange portion is formed on the opening periphery of the container body, and a fitting portion is formed on the outer periphery of the lid body. Is fitted on the flange.

ところが、この種の従来の容器においては、蓋体を閉鎖状態から開放させる場合、蓋体の嵌合部が容器本体のフランジ部に対して比較的強固に外嵌されているため、片手操作にて、この嵌合部をフランジ部から離脱させて蓋体を開放させるのが困難であるという問題があった。   However, in this type of conventional container, when the lid body is opened from the closed state, the fitting portion of the lid body is relatively tightly fitted to the flange portion of the container body. Thus, there is a problem that it is difficult to separate the fitting portion from the flange portion to open the lid.

この発明は、このような従来の技術に存在する問題点に着目してなされたものである。その目的は、蓋体を容器本体に対する閉鎖状態から開放させる場合、蓋体の嵌合部を、片手操作にて、容器本体のフランジ部への外嵌状態から簡単に離脱させることができて、蓋体を容易に開放させることができる容器を提供することにある。   The present invention has been made paying attention to such problems existing in the prior art. The purpose is to open the lid from the closed state with respect to the container body, the fitting part of the lid can be easily detached from the external fitting state to the flange part of the container body by one-hand operation, An object of the present invention is to provide a container whose lid can be easily opened.

上記の目的を達成するために、請求項１に記載の発明は、上面を開口し、開口縁にはフランジ部が形成された合成樹脂シート製の椀状の容器本体と、その容器本体に開閉可能に設けられ、容器本体に対する閉鎖状態で前記フランジ部に外嵌可能な嵌合部を外周縁に有する合成樹脂シート製の円板状の蓋体とを備えた容器において、前記蓋体の嵌合部の周壁には、平面視において前記嵌合部から外側へはみ出しかつ外方へ向かって膨らむ屈曲部としての単一の膨出部が形成されているとともに、前記膨出部の下端両側縁と前記嵌合部の周壁下端縁との間には前記円板状蓋体の外周方向に延びる平面視三角形状の一対のヒレ部が接続形成されていることを特徴とする容器に係る。   In order to achieve the above object, the invention described in claim 1 is characterized in that a bowl-shaped container body made of a synthetic resin sheet having an upper surface opened and a flange portion formed on an opening edge, and the container body opened and closed. In a container provided with a disc-shaped lid made of a synthetic resin sheet, which is provided in a closed state with respect to the container main body and has a fitting portion that can be fitted on the flange portion at the outer peripheral edge, the fitting of the lid A single bulging portion as a bent portion that protrudes outward from the fitting portion and bulges outward in a plan view is formed on the peripheral wall of the joint portion, and both lower side edges of the bulging portion A pair of fins having a triangular shape in plan view extending in the outer peripheral direction of the disc-shaped lid are connected and formed between the lower end edge of the peripheral wall of the fitting portion and the fitting portion.

Hereinafter, the embodiments of the invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, a container 11 of this embodiment includes a substantially bowl-shaped container body 12 having an upper surface made of a synthetic resin sheet such as polypropylene, polystyrene, polyethylene, polyethylene terephthalate, and the like, and the container body 12 and a substantially disc-shaped lid 13 made of a synthetic resin sheet made of the same material or different material. The lid 13 is attached to the opening of the container body 12 so as to be detachable, and the opening of the container body 12 is closed.

前記容器本体１２の開口周縁には断面ほぼ横Ｌ字状のフランジ部１４が一体に突出形成され、そのフランジ部１４の周壁外面には環状の係合凹部１４ａが下方へ向かって折り曲げ形成されている。蓋体１３の外周縁には嵌合部１５が形成され、その嵌合部１５は、前記容器本体１２のフランジ部１４の上面に対向する環状段差部１５ｂと、その環状段差部１５ｂの外周部分から下方へ向かって折り曲げ形成された環状の係合突部１５ａとなっている。そして、容器本体１２の開口部に蓋体１３を取り付けたとき、嵌合部１５がフランジ部１４に外嵌されて、環状段差部１５ｂがフランジ部１４の上面に接するとともに、係合突部１５ａが係合凹部１４ａに係合されて、蓋体１３が容器本体１２に対する閉鎖状態に所要の強度で止着保持されるようになっている。   A flange portion 14 having a substantially L-shaped cross section is integrally formed on the peripheral edge of the opening of the container body 12, and an annular engagement recess 14 a is formed on the outer peripheral surface of the flange portion 14 so as to be bent downward. Yes. A fitting portion 15 is formed on the outer peripheral edge of the lid 13, and the fitting portion 15 includes an annular step portion 15 b that faces the upper surface of the flange portion 14 of the container body 12, and an outer peripheral portion of the annular step portion 15 b. The ring-shaped engaging protrusion 15a is bent downward from the bottom. When the lid 13 is attached to the opening of the container main body 12, the fitting portion 15 is externally fitted to the flange portion 14, the annular step portion 15b is in contact with the upper surface of the flange portion 14, and the engagement protrusion 15a. Is engaged with the engagement recess 14a, and the lid 13 is fixedly held in a closed state with respect to the container main body 12 with a required strength.

図１〜図３に示すように、前記蓋体１３の嵌合部１５の環状段差部１５ｂから係合突部１５ａにかけて蓋体１３の周壁外面には、屈曲部としての膨出部１６が外方へ向かって膨らむように形成されている。この膨出部１６は全体の輪郭がほぼ球殻状をなすように形成され、その外面の両側には一対の窪み部１６ａが内部空間側に向かって突出するように形成されている。膨出部１６の下端両側縁と嵌合部１５の周壁下端縁との間には、平面ほぼ三角形状の一対のヒレ部１７が接続形成されている。   As shown in FIG. 1 to FIG. 3, a bulging portion 16 as a bent portion is formed on the outer surface of the peripheral wall of the lid body 13 from the annular stepped portion 15b of the fitting portion 15 of the lid body 13 to the engaging protrusion 15a. It is formed to swell toward the direction. The bulging portion 16 is formed so that the entire outline has a substantially spherical shell shape, and a pair of recess portions 16a are formed on both sides of the outer surface so as to protrude toward the inner space side. A pair of fin portions 17 having a substantially triangular shape are connected between both side edges of the lower end of the bulging portion 16 and the lower edge of the peripheral wall of the fitting portion 15.

そして、図３に鎖線で示すように、蓋体１３を容器本体１２に対する閉鎖状態から開放させるとき、この膨出部１６を上方へつまみ上げれば、膨出部１６の後部側において環状段差部１５ｂがフランジ部１４の上面の上面位置あるいはその近傍位置の部分を支点Ｐとして、そのフランジ部１４から離間する方向へ屈曲変形させる。これにより、ヒレ部１７を介して嵌合部１５がフランジ部１４の上面から持ち上げられ、そのフランジ部１４に対する外嵌状態から離脱されるようになっている。   As shown by a chain line in FIG. 3, when the lid 13 is released from the closed state with respect to the container body 12, if the bulging portion 16 is lifted upward, the annular step portion 15 b is formed on the rear side of the bulging portion 16. Is bent and deformed in a direction away from the flange portion 14 with the upper surface position of the upper surface of the flange portion 14 or a portion in the vicinity thereof as a fulcrum P. Thereby, the fitting part 15 is lifted from the upper surface of the flange part 14 via the fin part 17, and is detached from the external fitting state with respect to the flange part 14.

次に、前記のように構成された容器１１の作用を説明する。さて、この容器１１に惣菜等の収容物を収容する場合には、図１に示すように、容器本体１２の開口部を開放した状態で、その容器本体１２内に収容物を収容する。その後、蓋体１３を容器本体１２の開口部に被着すると、蓋体１３の嵌合部１５が容器本体１２のフランジ部１４に外嵌されるとともに、係合突部１５ａが係合凹部１４ａに係合されて、蓋体１３が容器本体１２に対する閉鎖位置にほぼ密封状態で所要の強度で止着される。   Next, the operation of the container 11 configured as described above will be described. Now, when accommodating things, such as a side dish, in this container 11, as shown in FIG. 1, in the state which opened the opening part of the container main body 12, accommodated things in the container main body 12 are accommodated. Thereafter, when the lid body 13 is attached to the opening of the container body 12, the fitting portion 15 of the lid body 13 is externally fitted to the flange portion 14 of the container body 12, and the engagement protrusion 15a is engaged with the engagement recess 14a. The lid body 13 is fixed to the closed position with respect to the container main body 12 with a required strength in a substantially sealed state.

そして、蓋体１３を閉鎖状態から開放させて、惣菜等の収容物を取り出す場合には、図３に鎖線で示すように、蓋体１３の外周の膨出部１６をつまみ上げれば、蓋体１３の嵌合部１５がフランジ部１４の上面位置あるいはその近傍位置の部分を支点Ｐとして、フランジ部１４から離間する上方に向かって屈曲変形させる。すると、ヒレ部１７を介して嵌合部１５の手前側がフランジ部１４の上面から持ち上げられ、デッドポイントを越えてその持ち上げ位置に保持され、係合凹部１４ａを含むフランジ部１４に対する外嵌状態から離脱される。よって、この状態で膨出部１６やヒレ部１７を持って、蓋体１３を容器本体１２上から容易に取り外して、容器本体１２の開口部を開放させることができる。   Then, when the lid 13 is opened from the closed state and a stored item such as sugar beet is taken out, as shown by a chain line in FIG. 3, if the bulging portion 16 on the outer periphery of the lid 13 is picked up, the lid The 13 fitting portions 15 are bent and deformed upward away from the flange portion 14 with the upper surface position of the flange portion 14 or a portion in the vicinity thereof as a fulcrum P. Then, the front side of the fitting portion 15 is lifted from the upper surface of the flange portion 14 via the fin portion 17 and is held at the lifted position beyond the dead point, and from the external fitting state with respect to the flange portion 14 including the engaging recess 14a. Will be withdrawn. Thus, in this state, the bulging portion 16 and the fin portion 17 are held, and the lid 13 can be easily removed from the container body 12 to open the opening of the container body 12.

以上のように、膨出部１６を上方へ屈曲させるのみで蓋体１３を開放可能な状態にすることができ、蓋体１３の開放操作を片手で、かつワンタッチで行うことが可能になる。なお、この実施形態では、膨出部１６に一対の窪み部１６ａが形成されているため、その窪み部１６ａを持って、蓋体１３を開放することが可能である。また、窪み部１６ａにより膨出部１６の剛性を向上できる。   As described above, the lid 13 can be opened only by bending the bulging portion 16 upward, and the lid 13 can be opened with one hand and with one touch. In addition, in this embodiment, since a pair of hollow part 16a is formed in the bulging part 16, it is possible to open the cover body 13 with the hollow part 16a. Moreover, the rigidity of the bulging part 16 can be improved by the hollow part 16a.

なお、前記実施形態において、容器本体１２の外周にヒンジ部を介して蓋体１３を一体に連結形成し、蓋体１３のヒンジ部と反対側の外周に膨出部１６を形成して具体化することも可能である。 In the above embodiment, the lid 13 is connected integrally formed through a hinge portion on the outer periphery of the container body 12, embodied to form a bulged portion 16 on the opposite side outer circumference of the hinge part of the lid 13 It is also possible to do.
