Description

本発明は、食品を収容するのに適した包装用容器に関する。   The present invention relates to a packaging container suitable for containing food.

従来から、弁当、寿司、惣菜、肉や刺身等の生鮮品、調理素材といった各種の食品を収容する包装用容器として、発泡プラスチックからなる周側枠の内側に食品の収容部を有するプラスチック製の容器本体を配置し、透明な蓋体で覆うようにした包装用容器が知られている。この種の包装用容器は、容器本体の外周に周側枠を設けているので、容器本体と蓋体とからなる包装用容器よりも見栄えが良くなり、商品価値を高めることができるといった利点があり、さらに、内容物を加熱するために電子レンジにかける場合であれば、周側枠が備える断熱性のために持ち手が熱くならないといった利点がある。   Conventionally, as a packaging container for storing various foods such as bento, sushi, prepared dishes, fresh products such as meat and sashimi, and cooking materials, it has been made of plastic with a food container inside the peripheral frame made of foamed plastic. A packaging container in which a container body is arranged and covered with a transparent lid is known. Since this type of packaging container has a peripheral frame on the outer periphery of the container body, it has an advantage that it looks better than a packaging container consisting of a container body and a lid, and can increase the commercial value. In addition, if the contents are put on a microwave oven to heat the contents, there is an advantage that the handle does not become hot because of the heat insulation provided in the peripheral side frame.

この種の包装用容器は、図6(a)に示す如く、蓋52が周側枠51よりもやや大きく、そのため、蓋52が周側枠51と共に容器本体50の開口を覆うようにして容器本体50に取り付けられ、容器本体50のうち、周側枠51よりも上方に突出する外周部に凹部53が設けられる一方、蓋52には、該凹部53と係合する凸部54が設けられ、凹部53と凸部54とが嵌合することにより、蓋3が容器本体1に着脱自在に取り付けられる、いわゆる外嵌合タイプのものが知られている(特許文献1)。
特開2004−83089号公報
In this type of packaging container, as shown in FIG. 6A, the lid 52 is slightly larger than the peripheral frame 51, so that the lid 52 covers the opening of the container body 50 together with the peripheral frame 51. A concave portion 53 is provided on an outer peripheral portion of the container main body 50 that is attached to the main body 50 and protrudes above the peripheral side frame 51, while a convex portion 54 that engages with the concave portion 53 is provided on the lid 52. A so-called external fitting type in which the lid 3 is detachably attached to the container body 1 by fitting the concave portion 53 and the convex portion 54 is known (Patent Document 1).
JP 2004-83089 A

しかしながら、上記特許文献1に記載の包装用容器は、電子レンジなどで加熱した際に、容器内の食品から生じた蒸気により蓋52が加熱されて、蓋52の外周縁が外方に変形した場合には、図6(b)に示す如く、嵌合状態が解除されるおそれがあった。   However, when the packaging container described in Patent Document 1 is heated with a microwave oven or the like, the lid 52 is heated by steam generated from the food in the container, and the outer peripheral edge of the lid 52 is deformed outward. In such a case, as shown in FIG. 6B, the fitted state may be released.

そこで、本発明は、上記問題に鑑みてなされたもので、蓋を嵌めやすくしつつも、外れにくい包装用容器を提供することを課題とする。   Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a packaging container that can be easily fitted while a lid is not easily detached.

本発明に係る包装用容器は、上記課題を解決すべく構成されたもので、容器本体と、該容器本体を取り囲むようにして取り付けられる周側枠と、容器本体及び周側枠のそれぞれ開口を覆うようにして容器本体に着脱自在に取り付けられる蓋とを備える包装用容器において、容器本体は、内容物の収容部を構成する本体部と、該本体部の外周に沿って設けられる外周部とを備えると共に、該外周部は、容器本体のコーナー部において、上端が周側枠よりも上方に突出する上方から下方への折返部を備える一方、蓋は、容器本体の本体部と共に内容物の収容部を構成する蓋本体部と、該蓋本体部の外周に沿って設けられる蓋外周部とを備えると共に、該蓋外周部は、蓋のコーナー部において、前記折返部の上端側である凸部に外嵌する凹部を備え、容器本体の凸部と蓋の凹部とが凹凸嵌合することにより、蓋が容器本体に着脱自在に取り付けられるよう構成されてなることを特徴とする。   A packaging container according to the present invention is configured to solve the above-described problems, and includes a container main body, a peripheral frame attached so as to surround the container main body, and an opening in each of the container main body and the peripheral frame. In a packaging container comprising a lid that is detachably attached to the container body so as to cover, the container body includes a main body part that constitutes a content storage part, and an outer peripheral part provided along an outer periphery of the main body part And the outer peripheral portion includes a folded portion from the upper side to the lower side whose upper end protrudes upward from the peripheral side frame at the corner portion of the container main body, while the lid includes the main body portion of the container main body. A lid main body part that constitutes the housing part, and a lid outer peripheral part provided along the outer periphery of the lid main body part, and the lid outer peripheral part is a convex that is the upper end side of the folded part at the corner part of the lid With a recess that fits around By the convex portion and the concave portion of the lid of the container body is projection fitting lid is characterized by comprising been configured to be removably attached to the container body.

かかる構成によれば、容器本体の凸部を内側及び外側から挟み込んで蓋の凹部が嵌合するように機能する。このような容器本体と蓋との嵌合構造(蓋の取り付け構造)は、いわゆる内外嵌合タイプとなるため、従来の包装用容器に比べて嵌合力が強く、蓋が外周縁外方へ変形することを抑制し、蓋が不用意に外れたりすることはなくなる。しかも、その内外嵌合タイプからなる容器本体と蓋との嵌合構造が包装用容器の全周に亘って設けられるとすれば、その嵌合力の強さにより、逆に蓋を嵌めにくいという問題が生じるが、本発明では、部分的に嵌合構造を設けているため、そのような問題が生じることもない。即ち、本発明に係る包装用容器によれば、蓋を嵌めやすくしつつも、外れにくい、といった一見相反する二つの事項を解決することができるのである。   According to this structure, it functions so that the convex part of a container main body may be inserted | pinched from the inner side and the outer side, and the recessed part of a lid | cover may fit. Such a fitting structure between the container body and the lid (attachment structure of the lid) is a so-called inner / outer fitting type, so the fitting force is stronger than the conventional packaging container, and the lid is deformed outward from the outer periphery. This prevents the lid from being inadvertently removed. Moreover, if the fitting structure between the container body and the lid of the inner / outer fitting type is provided over the entire circumference of the packaging container, it is difficult to fit the lid by the strength of the fitting force. However, in the present invention, such a problem does not occur because the fitting structure is partially provided. That is, according to the packaging container according to the present invention, it is possible to solve two seemingly contradictory matters such as making it easy to fit the lid, but being difficult to come off.

また、本発明に係る包装用容器は、前記容器本体の凸部は、所定箇所に係合用凸部又は係合用凹部の何れか一方を備え、前記蓋の凹部は、容器本体の係合用凸部又は係合用凹部の何れか一方と係合する係合用凸部又は係合用凹部の何れか他方を備える構成を採用することができる。   Further, in the packaging container according to the present invention, the convex portion of the container body is provided with either one of the convex portion for engagement or the concave portion for engagement at a predetermined location, and the concave portion of the lid is the convex portion for engagement of the container body. Or the structure provided with either the other of the convex part for engagement engaged with any one of the concave parts for engagement, or the concave part for engagement is employable.

かかる構成によれば、容器本体の凸部全体と蓋の凹部全体との嵌合に際し、それぞれ係合用凸部と係合用凹部とを係合させることにより、容器本体への蓋の取り付け状態をより確実に維持することができるようになる。   According to such a configuration, when the entire convex portion of the container body and the entire concave portion of the lid are fitted, the engaging convex portion and the engaging concave portion are engaged with each other, so that the attachment state of the lid to the container main body is further improved. It can be reliably maintained.

また、本発明に係る包装用容器は、前記容器本体の折返部は、容器本体の各辺の中間部に向かうに従って漸次低くなるような構成を採用することができる。   Moreover, the packaging container which concerns on this invention can employ | adopt the structure that the folding | returning part of the said container main body becomes gradually low as it goes to the intermediate part of each side of a container main body.

かかる構成によれば、容器に収容された内容物をより視認しやすくすることができ、弁当や惣菜など、消費者による購買意欲の向上が期待できる。   According to such a configuration, it is possible to make the contents contained in the container easier to visually recognize, and it can be expected that the consumer's willingness to purchase such as bento and side dishes will be improved.

以上の如く、本発明は、容器本体に部分的に設けられた凸部と、蓋に部分的に設けられた凸部とが凹凸嵌合し、容器本体と蓋との嵌合構造がいわゆる内外嵌合タイプとなるため、嵌合構造が部分的にしか設けられていなくても、容器本体と蓋との嵌合力は強く、不用意に蓋が外れてしまうことを好適に防止することができ、且つ、蓋を嵌めやすく、外しやすいという相反する効果を満足することができる。   As described above, according to the present invention, the convex portion provided partially on the container body and the convex portion provided partially on the lid are unevenly fitted, and the fitting structure between the container main body and the lid is a so-called inside / outside. Because it is a fitting type, even if the fitting structure is only partially provided, the fitting force between the container body and the lid is strong, and it is possible to suitably prevent the lid from being inadvertently removed. Moreover, it is possible to satisfy the conflicting effect that the lid can be easily fitted and removed.

以下、本発明の一実施形態に係る包装用容器(以下、単に「容器」という)について、図面を参酌しつつ説明する。尚、上記従来の包装用容器に関する説明のうち、本実施形態に係る包装用容器にも共通する部分については、本実施形態に係る包装用容器に関する説明として、それを援用可能であることは言うまでもない。また、以下の説明において、「外方」、「内方」なる用語が用いられることがあるが、「外方」とは、容器の中心から見て水平方向に広がる方向をいい、「内方」とは、水平方向において外側から容器の中心側に向かう方向をいう。但し、これら「外方」、「内方」なる用語は、水平方向と一致する場合のみならず、それに対してある程度の角度範囲で傾斜する方向も含むものである。   Hereinafter, a packaging container (hereinafter simply referred to as “container”) according to an embodiment of the present invention will be described with reference to the drawings. In addition, it cannot be overemphasized that about the part which is common also in the packaging container which concerns on this embodiment among the description regarding the said conventional packaging container, it can be used as description regarding the packaging container which concerns on this embodiment. Yes. In addition, in the following description, the terms “outward” and “inward” may be used. “Outward” refers to a direction spreading in the horizontal direction when viewed from the center of the container. "" Refers to the direction from the outside toward the center of the container in the horizontal direction. However, the terms “outward” and “inward” include not only the case where they coincide with the horizontal direction, but also the direction in which they are inclined within a certain angle range.

図1は、本実施形態に係る容器の平面図を示す。容器は、容器本体1と、該容器本体1の外周を取り囲むようにして容器本体1の外周縁に取り付けられる周側枠2と、容器本体1に着脱自在に取り付けられる蓋3とを備える。言い換えれば、容器は、周側枠2の内側に容器本体1が設けられ、該容器本体1を蓋体3で覆うように構成したものである。尚、図1においては、蓋3は、一部(右上の四分の一の領域)のみ表され、それ以外は表していない。従って、図1の右上の四分の一の領域は、蓋3が容器本体1及び周側枠2を覆った状態で表され、その他の四分の三の領域は、蓋3が無い状態、即ち、容器本体1及び周側枠2が露出した状態で表される。   FIG. 1 shows a plan view of a container according to this embodiment. The container includes a container body 1, a peripheral side frame 2 that is attached to the outer periphery of the container body 1 so as to surround the outer periphery of the container body 1, and a lid 3 that is detachably attached to the container body 1. In other words, the container is configured such that the container main body 1 is provided inside the peripheral frame 2 and the container main body 1 is covered with the lid 3. In FIG. 1, only a part of the lid 3 (the upper right quarter region) is shown, and the rest is not shown. Accordingly, the upper right quarter of FIG. 1 is represented with the lid 3 covering the container body 1 and the peripheral frame 2, and the other three quarters of the state without the lid 3. That is, the container body 1 and the peripheral frame 2 are exposed.

容器は、閉蓋状態、即ち、容器本体1に蓋3が取り付けられた状態で、略直方体をなす、いわゆる角形容器である。そのため、容器は、平面視にて四角形(長方形)を呈しており、容器本体1、周側枠2、蓋3の何れもが平面視にて四角形を呈する。但し、厳密に言えば、容器の各コーナー部は、直角ではなく、角を取って丸みが付けられる。本実施形態においては、このコーナー部(容器の四隅)において、容器本体1と蓋3との嵌合構造が採用され、容器本体1に蓋3を着脱自在に取り付けることができるようになっているが、これについては後述する。   The container is a so-called rectangular container that forms a substantially rectangular parallelepiped in a closed state, that is, in a state where the lid 3 is attached to the container body 1. Therefore, the container has a quadrangle (rectangle) in plan view, and all of the container main body 1, the peripheral frame 2, and the lid 3 have a quadrangle in plan view. Strictly speaking, however, the corners of the container are not round but rounded. In this embodiment, a fitting structure between the container main body 1 and the lid 3 is employed at the corner portions (four corners of the container), and the lid 3 can be detachably attached to the container main body 1. This will be described later.

容器本体1及び蓋3は、プラスチックシート(合成樹脂製シート)を成形して構成され、プラスチックとしては、例えば、ポリプロピレン(PP)、ポリエチレンテレフタレート(PET)、あるいはポリスチレン(PS)等の材質が用いられる。また、容器本体1は、着色が施されて不透明であってもよく、蓋3を介して内容物を視認することができる点で、蓋3は透明であるのが好ましい。一方、周側枠2は、発泡プラスチック製の帯状素材を容器本体1の外周縁に沿うようにして四角形(方形)に折り曲げ、さらに、端部同士を接着剤で固定したものである。周側枠2は、高級感を醸し出すために外側表面に木目等の装飾が施されるようにしてもよい。   The container body 1 and the lid 3 are formed by molding a plastic sheet (synthetic resin sheet). As the plastic, for example, a material such as polypropylene (PP), polyethylene terephthalate (PET), or polystyrene (PS) is used. It is done. The container body 1 may be colored and opaque, and the lid 3 is preferably transparent in that the contents can be visually recognized through the lid 3. On the other hand, the peripheral frame 2 is formed by bending a foamed plastic strip-like material into a quadrangle (square) along the outer peripheral edge of the container body 1 and fixing the ends with an adhesive. The peripheral frame 2 may be decorated with a grain or the like on the outer surface in order to create a high-class feeling.

蓋3の大きさは、周側枠2の大きさと同じかそれよりもやや大きく構成され、蓋3の外周縁が周側枠2の外側に張り出すように構成されている。また、その外周縁は、図示しないが、プレスによる細かな凹凸加工やエンボス加工を施すことにより、側面視にて波形(正弦波、三角波、台形波等)の外縁線、即ち、直線ではない外縁線を備えるようになっている。これらにより、蓋3の外周縁のエッジの鋭利さが解消されるため、蓋3を開閉する際の指先を保護することができ、また、包装フィルム(図示しない)を使用してラッピングする際に包装フィルムが裂断するのを防止することができる。さらに、蓋3の外周縁の強度が増し、蓋3が裂断するのを防止する効果もある。尚、蓋3の外周縁の一部に開蓋用の指掛けを設けてもよく、また、上記した外周縁のエッジの鋭利さを解消するための種々の施策は、容器本体1の外周縁に施してもよい。   The size of the lid 3 is configured to be the same as or slightly larger than the size of the peripheral side frame 2, and the outer peripheral edge of the lid 3 is configured to project outside the peripheral side frame 2. In addition, the outer peripheral edge is not shown in the figure, but by applying fine uneven processing and embossing by pressing, the outer peripheral line of a waveform (sine wave, triangular wave, trapezoidal wave, etc.) in side view, that is, an outer edge that is not a straight line It comes to have a line. By these, since the sharpness of the edge of the outer periphery of the lid | cover 3 is eliminated, the fingertip at the time of opening and closing the lid | cover 3 can be protected, and when wrapping using a packaging film (not shown) The packaging film can be prevented from tearing. Further, the strength of the outer peripheral edge of the lid 3 is increased, and there is an effect of preventing the lid 3 from tearing. It should be noted that a finger hook for opening the lid may be provided on a part of the outer peripheral edge of the lid 3, and various measures for eliminating the sharpness of the edge of the outer peripheral edge are provided on the outer peripheral edge of the container body 1. You may give it.

図2は、容器本体1と蓋3との嵌合構造が設けられる容器のコーナー部における拡大断面図(図1のA−A線断面図)を示す。容器本体1は、大きく分けると、(下方に)窪んで食品の収容部を構成する本体部10と、該本体部10の外周に沿って設けられる外周部13とからなる。また、蓋3は、大きく分けると、(上方に)膨らんで容器本体1の本体部10と共に食品の収容部を概略的に構成する蓋本体部30と、該蓋本体部30の外周に沿って設けられる蓋外周部34とからなる。   FIG. 2 shows an enlarged cross-sectional view (cross-sectional view taken along the line AA in FIG. 1) at the corner portion of the container in which the fitting structure between the container main body 1 and the lid 3 is provided. The container main body 1 is roughly divided into a main body portion 10 that is recessed (downward) to form a food storage portion, and an outer peripheral portion 13 that is provided along the outer periphery of the main body portion 10. The lid 3 is roughly divided into a lid main body portion 30 that swells (upward) and roughly constitutes a food container together with the main body portion 10 of the container main body 1, and the outer periphery of the lid main body portion 30. And a lid outer peripheral portion 34 provided.

容器本体1の本体部10は、底部11と、該底部11の外周から上方に延びる(立ち上がる)、より詳しくは、上方側ほど外方に膨らむように傾斜して上方に延びる、食品の収容部の周壁を構成する周壁部12とからなる。底部11は、さらに、底面部11aと、該底面部11aの周りに配置される環状凹部11bとからなり、周壁部12は、環状凹部11bにて底部11と接続される。このように、容器本体1は、底が平坦で、上方に向かって横断面積が漸次増加する形状となっている。また、容器本体1の底部11は、周側枠2の下端よりも高い位置に設定され、容器本体1の底を浮かせるようにしている。このような構成は、容器本体1を積み重ねて載置するのに適している。   The main body 10 of the container body 1 extends from the outer periphery of the bottom 11 and the outer periphery of the bottom 11 (in more detail, more specifically), and more specifically, a food container that extends upward while inclining so as to bulge outward toward the upper side. And a peripheral wall portion 12 constituting the peripheral wall. The bottom portion 11 further includes a bottom surface portion 11a and an annular recess portion 11b arranged around the bottom surface portion 11a. The peripheral wall portion 12 is connected to the bottom portion 11 at the annular recess portion 11b. Thus, the container body 1 has a flat bottom and a shape in which the cross-sectional area gradually increases upward. Further, the bottom 11 of the container main body 1 is set at a position higher than the lower end of the peripheral frame 2 so as to float the bottom of the container main body 1. Such a configuration is suitable for stacking and mounting the container main body 1.

容器本体1の外周部13は、周壁部12からさらに上方に延びる(立ち上がる)、より詳しくは、傾斜することなく上方に延びる起立部14と、該起立部14から外方に延びる(張り出す)、より詳しくは、傾斜することなく外方に延びる頂部15と、該頂部15から下方に延びる(垂下する)、より詳しくは、傾斜することなく下方に延びる垂下部16と、該垂下部16から外方に延びる(張り出す)、より詳しくは、階段状に屈曲しつつ外方に延びる取付部17とからなる。   The outer peripheral portion 13 of the container body 1 further extends (rises) further from the peripheral wall portion 12, and more specifically, rises 14 that extends upward without inclining, and extends outward (extends) from the stand 14. More specifically, the apex 15 extends outward without being inclined, and extends downward (hangs down) from the apex 15, and more specifically, the drooping portion 16 extending downward without inclining, and the drooping portion 16. It extends outward (projects), and more specifically, includes a mounting portion 17 that extends outward while bending in a stepped manner.

垂下部16は、さらに、起立部14と対峙し且つ該起立部14に対応した高さを有する第一部位16aと、該第一部位16aから下方に延び(垂下し)、周壁部12と対峙する第二部位16bとからなる。周壁部12の上端、即ち、起立部14の下端は、垂下部16の第二部位16bの上端、即ち、垂下部16の第一部位16aの下端、と同じ又は略同じ高さ位置に設定され、しかも、それは、周側枠2の上端と同じ又は略同じ高さ位置に設定されている。   The hanging portion 16 further faces the upright portion 14 and has a first portion 16a having a height corresponding to the rising portion 14, and extends downward (hangs down) from the first portion 16a, and faces the peripheral wall portion 12. And a second portion 16b. The upper end of the peripheral wall portion 12, that is, the lower end of the standing portion 14 is set at the same or substantially the same height as the upper end of the second portion 16 b of the hanging portion 16, that is, the lower end of the first portion 16 a of the hanging portion 16. Moreover, it is set at the same or substantially the same height as the upper end of the peripheral frame 2.

そこで、起立部14、頂部15及び垂下部16は、容器本体1の外周部13において、上方から下方に折り返される折返部18を構成し、また、起立部14、頂部15及び垂下部16の第一部位16aは、容器本体1の外周部13において、(上方に)膨らんだ凸部18a、より詳しくは、周側枠2よりも上方に突出した凸部18aを構成する。即ち、凸部18aは、折返部18の一部であり、より詳しくは、折返部18の上端側に位置する構成である。   Therefore, the upright portion 14, the top portion 15, and the hanging portion 16 constitute a folded portion 18 that is folded back from above in the outer peripheral portion 13 of the container body 1, and the rising portions 14, the top portion 15, and the hanging portion 16 The one portion 16 a constitutes a convex portion 18 a that swells (upward) in the outer peripheral portion 13 of the container body 1, more specifically, a convex portion 18 a that protrudes upward from the peripheral side frame 2. That is, the convex portion 18 a is a part of the folded portion 18, and more specifically, is configured to be positioned on the upper end side of the folded portion 18.

取付部17は、周側枠2の内壁に設けられた、より詳しくは、内壁のうち、中間箇所よりも上方箇所にて周回方向に沿って設けられたスリット21に挿入され、例えば、取付部17を固着するために接着剤(図示しない)を使用して容器本体1と周側枠2とを一体化させる。尚、容器本体1と周側枠2を一体化する手段としては、接着剤や熱融着といった固着手段に限定されず、例えば、取付部17が周側枠2の内壁又はスリット21に食い込むようにしてもよいし、取付部17がスリット21から脱落することが無いのであれば、接着剤や熱融着といった固着手段を用いることなく、単に周側枠2を容器本体1の周りに巻いて取り付けるだけであってもよい。   The attachment portion 17 is provided on the inner wall of the peripheral frame 2. More specifically, the attachment portion 17 is inserted into a slit 21 provided along the circumferential direction at a location above the intermediate location on the inner wall. In order to fix 17, the container body 1 and the peripheral frame 2 are integrated using an adhesive (not shown). The means for integrating the container body 1 and the peripheral frame 2 is not limited to a fixing means such as an adhesive or heat fusion. For example, the mounting portion 17 bites into the inner wall or the slit 21 of the peripheral frame 2. Alternatively, if the attachment portion 17 does not fall off from the slit 21, the peripheral side frame 2 is simply wrapped around the container body 1 without using a fixing means such as an adhesive or heat fusion. You may just attach.

蓋本体部30は、天井部31と、該天井部31の外周から下方に延びる(垂下する)、より詳しくは、下方側ほど外方に膨らむように傾斜して下方に延びる、食品の収容部の周壁を構成する周壁部32と、該周壁部32から外方に延びる(張り出す)、より詳しくは、傾斜することなく外方に延びる段落部33とからなる。このように、蓋3は、天井が平坦で、下方に向かって横断面積が漸次増加する形状となっている。   The lid body portion 30 extends downward (hangs down) from the outer periphery of the ceiling portion 31 and more specifically, the food storage portion that inclines so as to bulge outward toward the lower side and extends downward. The peripheral wall part 32 which comprises this peripheral wall, and the paragraph part 33 extended outward from this peripheral wall part 32 (overhang | projection), and more specifically extended outwardly without inclining. Thus, the lid 3 has a flat ceiling and a shape in which the cross-sectional area gradually increases downward.

蓋外周部34は、段落部33から上方に延びる(立ち上がる)、より詳しくは、傾斜することなく上方に延びる起立部35と、該起立部35から外方に延びる(張り出す)、より詳しくは、傾斜することなく外方に延びる頂部36と、該頂部36から下方に延びる(垂下する)、より詳しくは、傾斜することなく下方に延びる垂下部37と、該垂下部37から外方に延びる(張り出す)、より詳しくは、傾斜することなく外方に延びる第一鍔部38と、該第一鍔部38から下方に延びる(垂下する)、より詳しくは、傾斜することなく下方に延びる第二鍔部39と、該第二鍔部39から外方に延びる(張り出す)、より詳しくは、傾斜することなく外方に延びる縁部40(容器の外周縁)とからなる。   The lid outer peripheral portion 34 extends (rises) upward from the paragraph portion 33, more specifically, an upright portion 35 that extends upward without inclining, and extends (extends) outward from the upright portion 35, more specifically A top portion 36 extending outwardly without being inclined, and extending downward (hanging down) from the top portion 36, more specifically, a hanging portion 37 extending downward without being inclined, and extending outwardly from the hanging portion 37. More specifically, the first flange 38 extends outward without being inclined, and extends downward (hangs down) from the first flange 38, and more specifically extends downward without being inclined. It consists of the 2nd collar part 39, and the edge part 40 (outer peripheral edge of a container) extended outward from this 2nd collar part 39, and more specifically, extending outward, without inclining.

段落部33の先端、即ち、起立部35の下端は、第一鍔部38の基端、即ち、垂下部37の下端、と同じ又は略同じ高さ位置に設定され、しかも、それは、周側枠2の上端と同じ又は略同じ高さ位置に設定されている。そして、起立部35は、容器本体1の起立部14より僅かに高く形成され、該起立部14と密接又はそれに近い状態で対峙する。頂部36は、容器本体1の頂部15より僅かに幅広に形成され、該頂部15と密接又はそれに近い状態で対峙する。垂下部37は、容器本体1の垂下部16の第一部位16aよりも僅かに高く形成され、該第一部位16aと密接又はそれに近い状態で対峙する。   The leading end of the paragraph 33, that is, the lower end of the standing portion 35 is set at the same or substantially the same height as the base end of the first flange 38, that is, the lower end of the hanging portion 37, and it is It is set at the same or substantially the same height as the upper end of the frame 2. And the standing part 35 is formed slightly higher than the standing part 14 of the container main body 1, and it opposes this standing part 14 in the state close | similar or close to it. The top portion 36 is formed to be slightly wider than the top portion 15 of the container main body 1, and faces the top portion 15 in a state of being close or close thereto. The drooping portion 37 is formed slightly higher than the first portion 16a of the drooping portion 16 of the container body 1 and faces the first portion 16a in a state of being in close proximity or close thereto.

そのため、起立部35、頂部36及び垂下部37は、蓋外周部34において、(上方に)窪んだ凹部41、より詳しくは、周側枠2よりも上方に位置して下方が開放された凹部41を構成する。そして、該凹部41が容器本体1の凸部18aに外嵌する、言い換えれば、容器本体1の凸部18aが蓋3の凹部41に嵌入することにより、蓋3は、容器本体1に着脱自在に取り付けられる。   Therefore, the standing portion 35, the top portion 36, and the hanging portion 37 are recessed portions 41 that are recessed (upward) in the lid outer peripheral portion 34, more specifically, recessed portions that are located above the peripheral side frame 2 and opened downward. 41 is constructed. The concave portion 41 is externally fitted to the convex portion 18 a of the container main body 1, in other words, the convex portion 18 a of the container main body 1 is fitted into the concave portion 41 of the lid 3, so that the lid 3 is detachable from the container main body 1. Attached to.

容器本体1の凸部18aは、(内方に)膨らんだ係合用凸部19を備える一方、蓋3の凹部41は、(内方に)窪んだ係合用凹部42を備える。該係合用凹部42は、蓋3が容器本体1に取り付けられ、蓋3の凹部41が容器本体1の凸部18aに外嵌した状態で、係合用凸部19と係合するようになっている。しかも、係合用凸部19及び係合用凹部42は、容器本体1に対する蓋3の着脱方向と交差する方向において凹凸係合(あるいは凹凸嵌合)するため、この凹凸係合(凹凸嵌合)の部分においては簡単に外せられないような構造となっている。そうであるから、係合用凸部19を備える容器本体1の凸部18aは、嵌合凸部としての機能を有する一方、係合用凹部42を備える蓋3の凹部41は、嵌合凹部としての機能を有し、このような容器本体1と蓋3との嵌合構造(蓋の取り付け構造)は、いわゆる内外嵌合タイプとなっている。   The convex portion 18a of the container body 1 includes an engaging convex portion 19 that swells (inward), while the concave portion 41 of the lid 3 includes an concave concave portion 42 that is concave (inward). The engaging recess 42 is adapted to engage with the engaging protrusion 19 in a state where the lid 3 is attached to the container body 1 and the recess 41 of the lid 3 is externally fitted to the protrusion 18 a of the container body 1. Yes. In addition, since the engaging convex portion 19 and the engaging concave portion 42 engage with each other in the direction intersecting the attaching / detaching direction of the lid 3 with respect to the container body 1 (or the uneven fitting), The structure is such that it cannot be easily removed. Therefore, while the convex part 18a of the container body 1 provided with the engaging convex part 19 has a function as a fitting convex part, the concave part 41 of the lid 3 provided with the engaging concave part 42 serves as a fitting concave part. Such a fitting structure (attachment structure of the lid) between the container body 1 and the lid 3 is a so-called inside / outside fitting type.

係合用凸部19及び係合用凹部42についてより詳しく言及すると、係合用凸部19は、起立部14の頂部15側の部位が容器本体1の中心側に向かって突出するように成形され、外面側が係合用凸部19として機能する一方、係合用凹部42は、起立部35の頂部36側の部位が蓋3の中心側(容器本体1の中心側と同じ)に向かって突出するように成形され、内面側が係合用凹部42として機能する。別の言い方をすれば、係合用凸部19は、凸部18aのうち、内側の側壁(起立部14)が内方に膨らむように形成される一方、係合用凹部42は、凹部41のうち、内側の側壁(起立部35)が内方(蓋3の中心側)に窪むように形成され、係合用凸部19の膨らみが係合用凹部42の窪みに係入することにより、容器本体1と蓋3とが一体化される。   The engagement convex portion 19 and the engagement concave portion 42 will be described in more detail. The engagement convex portion 19 is formed such that a portion on the top portion 15 side of the upright portion 14 protrudes toward the center side of the container body 1, and the outer surface. While the side functions as the engaging convex portion 19, the engaging concave portion 42 is formed so that a portion on the top portion 36 side of the standing portion 35 protrudes toward the center side of the lid 3 (the same as the central side of the container body 1). Thus, the inner surface side functions as the engaging recess 42. In other words, the engaging convex portion 19 is formed such that the inner side wall (standing portion 14) of the convex portion 18a swells inward, while the engaging concave portion 42 is formed of the concave portion 41. The inner side wall (standing portion 35) is formed so as to be recessed inward (center side of the lid 3), and the bulge of the engaging convex portion 19 is engaged with the concave portion of the engaging concave portion 42. The lid 3 is integrated.

このような内外嵌合は、見方を変えて捉えることができる。即ち、凹部41に形成されるのが係合用凹部42ではなく、同じく係合用凸部43が形成されるものとみなすことができる。そうなると、蓋3の凹部41の係合用凸部43が、それよりも上方に位置する容器本体1の凸部18aの係合用凸部19に係止されることにより、容器本体1の凸部18aと蓋3の凹部41とが凹凸嵌合するとみなすこともできる。   Such internal / external fitting can be grasped from a different perspective. That is, it can be considered that the concave portion 41 is not formed with the engaging concave portion 42 but is similarly formed with the engaging convex portion 43. Then, the engaging convex portion 43 of the concave portion 41 of the lid 3 is locked to the engaging convex portion 19 of the convex portion 18 a of the container main body 1 located above the convex portion 18 a of the container main body 1. It can also be considered that the concave and convex portions 41 of the lid 3 are concavo-convexly fitted.

凹部41の係合用凸部43についてより詳しく説明すると、該係合用凸部43は、蓋3の凹部41から(外方に)膨らんだものである。即ち、係合用凸部43は、起立部35の段落部33側の部位が容器本体1の中心側と反対側に向かって突出するように成形され、内面側が係合用凸部43として機能する。別の言い方をすれば、係合用凸部43は、凹部41のうち、内側の側壁(起立部35)が外方に膨らむように形成され、係合用凸部43の膨らみが係合用凸部19の膨らみを乗り越えて係合用凸部19に上方から係止されることにより、容器本体1と蓋3とが一体化される。   The engaging convex portion 43 of the concave portion 41 will be described in more detail. The engaging convex portion 43 swells (outward) from the concave portion 41 of the lid 3. That is, the engaging convex portion 43 is formed such that a portion of the standing portion 35 on the side of the paragraph portion 33 protrudes toward the side opposite to the center side of the container body 1, and the inner surface side functions as the engaging convex portion 43. In other words, the engaging convex portion 43 is formed such that the inner side wall (standing portion 35) of the concave portion 41 swells outward, and the bulging of the engaging convex portion 43 is the engaging convex portion 19. The container body 1 and the lid 3 are integrated with each other by overcoming the bulge and being locked to the engaging convex portion 19 from above.

前記第一鍔部38は、周側枠2の上面と対峙し、該上面に重ねられる部位であり、前記第二鍔部39は、周側枠2の上端側の外面と対峙し、該外面に重ねられる部位であり、そのため、周側枠2の上端に第一鍔部38、第二鍔部39及び縁部40からなる外周縁部44が覆い被せられる。これにより、容器本体1の開口はもちろん、周側枠2の開口が蓋3(の外周縁部44)によって完全に覆われ得る。尚、上述した蓋3の外周縁のエッジの鋭利さを解消するための種々の施策は、縁部40に施されるものである。   The first flange 38 faces the upper surface of the peripheral frame 2 and overlaps the upper surface, and the second flange 39 faces the outer surface on the upper end side of the peripheral frame 2 and the outer surface. Therefore, the outer peripheral edge 44 including the first flange 38, the second flange 39, and the edge 40 is covered on the upper end of the peripheral frame 2. Thereby, not only the opening of the container body 1 but also the opening of the peripheral side frame 2 can be completely covered by the lid 3 (the outer peripheral edge 44 thereof). Various measures for eliminating the sharpness of the edge of the outer periphery of the lid 3 described above are applied to the edge 40.

ところで、容器本体1の凸部18a(周側枠2から上方に突出する部位)は、図3に示す如く、容器本体1のコーナー部(容器本体1の四隅)に意図して設けられるものである。従って、容器本体1の各辺の中間部では、凸部18aは小さくなっているか、無くなっている。より詳しくは、容器本体1のコーナー部における凸部18aは、所定範囲においては一定形状であるのに対し、そこから外れると、各辺の中間部に向かうに従って漸次縮小していく形状となっており、各辺の中間箇所には形成されていない形態になっている。これは、容器本体1の長辺側(同図(a))、短辺側(同図(b))の何れにおいてでもある。   By the way, the convex part 18a (part protruding upward from the peripheral frame 2) of the container body 1 is intentionally provided at the corner parts (four corners of the container body 1) of the container body 1 as shown in FIG. is there. Therefore, the convex part 18a is small or missing in the intermediate part of each side of the container main body 1. More specifically, the convex portion 18a at the corner portion of the container body 1 has a constant shape within a predetermined range, but when it deviates from the convex portion 18a, the convex portion 18a gradually decreases toward the middle portion of each side. In other words, it is not formed in the middle of each side. This is on either the long side (same figure (a)) of the container main body 1, or the short side (same figure (b)).

また、言い方を変えると、容器本体1の折返部18(容器本体1の本体部10と容器本体1の取付部17とを連結する部位)の上端側は、容器本体1のコーナー部の所定範囲においては一定形状であるのに対し、そこから外れると、各辺の中間部に向かうに従って漸次低くなり、各辺の中間箇所にて最も低くなって周側枠2の上端と同じ又は略同じ高さ位置になる。これは、容器本体1の長辺側(同図(a))、短辺側(同図(b))の何れにおいてでもある。   In other words, the upper end side of the folded portion 18 of the container body 1 (the portion connecting the body portion 10 of the container body 1 and the mounting portion 17 of the container body 1) is a predetermined range of the corner portion of the container body 1 However, when it deviates from it, it gradually becomes lower toward the middle part of each side, becomes the lowest at the middle part of each side, and is the same or substantially the same height as the upper end of the peripheral frame 2. It becomes the position. This is on either the long side (same figure (a)) of the container main body 1, or the short side (same figure (b)).

また、係合用凸部19及び係合用凹部42(係合用凸部43)も、辺に沿って形成され、容器本体1あるいは蓋3のコーナー部においてのみ形成される(図1参照)。尚、係合用凸部19及び係合用凹部42(係合用凸部43)は、各コーナー部において、互いに交差する二辺のそれぞれに一対ずつ設けられている。   Further, the engaging convex portion 19 and the engaging concave portion 42 (engaging convex portion 43) are also formed along the side, and are formed only at the corner portion of the container body 1 or the lid 3 (see FIG. 1). Note that a pair of the engaging convex portion 19 and the engaging concave portion 42 (engaging convex portion 43) are provided on each of the two sides that intersect each other in each corner portion.

本実施形態に係る容器は、以上の構成からなり、容器本体1と蓋3とを部分的に嵌合させた内外嵌合構造としているので、従来の容器に比べて、嵌合力が強く、さらに、蓋3が熱などにより変形しにくい構造となっている。しかも、その内外嵌合構造が容器本体1と蓋3との全周に亘って設けられていないので、その嵌合力の強さにより、逆に蓋3を嵌めにくい、また、外しにくいという問題が生じることもない。即ち、本実施形態に係る容器によれば、蓋3を嵌めやすくしつつも、外れにくい、といった一見相反する二つの事項を簡潔な構成によって解決したものであり、電子レンジ加熱した場合でも不用意に外れない極めて有用なものとなり得る。   The container according to the present embodiment has the above-described configuration, and has an inner / outer fitting structure in which the container body 1 and the lid 3 are partially fitted, so that the fitting force is stronger than the conventional container, The lid 3 has a structure that is not easily deformed by heat or the like. Moreover, since the inner / outer fitting structure is not provided over the entire circumference of the container body 1 and the lid 3, there is a problem that the lid 3 is difficult to be fitted or removed due to the strength of the fitting force. It does not occur. That is, according to the container according to the present embodiment, two seemingly contradictory matters such as making the lid 3 easy to fit but difficult to come off are solved by a simple configuration, and even when heated in a microwave oven, it is inadvertent Can be extremely useful.

また、容器本体1の各辺の中間部では、コーナー部における段落部33が形成されておらず、該段落部33は、周壁部32に吸収された格好となる。そのため、容器本体1の各辺の中間部では、周壁部32の傾斜が緩やかになっており、且つ、その先端が外方にせり出すようになっている。この点、容器のコーナー部における外観と、容器の各辺の中間部における外観とが大きく異なることになり、全体のデザインを斬新なものにすることが可能となる。   Moreover, the paragraph part 33 in the corner part is not formed in the intermediate part of each side of the container main body 1, and the paragraph part 33 is absorbed by the peripheral wall part 32. Therefore, in the intermediate part of each side of the container main body 1, the inclination of the surrounding wall part 32 is gentle, and the front-end | tip protrudes outward. In this respect, the appearance at the corner portion of the container and the appearance at the intermediate portion of each side of the container are greatly different, and the overall design can be made novel.

尚、本発明は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変更が可能である。   In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

例えば、上記実施形態においては、容器本体1の凸部18a、蓋3の凹部41、のそれぞれ端部(詳しくは、上端部)に、係合用凸部19や係合用凹部42を設けるようにしているが、図4(a)に示す如く、途中箇所に設けるようにしてもよい。また、上記実施形態においては、係合用凸部19を容器本体1の凸部18a側に、係合用凹部42を蓋3の凹部41側に、設けているが、同図に示す如く、容器本体1の凸部18aに係合用凹部19’を設けると共に、蓋3の凹部41に係合用凸部42’を設けるようにしてもよい。   For example, in the above-described embodiment, the engaging convex portion 19 and the engaging concave portion 42 are provided at the end portions (specifically, the upper end portion) of the convex portion 18 a of the container body 1 and the concave portion 41 of the lid 3. However, as shown in FIG. 4A, it may be provided in the middle. Moreover, in the said embodiment, although the convex part 19 for engagement is provided in the convex part 18a side of the container main body 1, and the recessed part 42 for engagement is provided in the concave part 41 side of the lid | cover 3, as shown in the figure, a container main body is provided. The engaging concave portion 19 ′ may be provided in one convex portion 18 a and the engaging convex portion 42 ′ may be provided in the concave portion 41 of the lid 3.

また、上記実施形態においては、容器本体1の凸部18aのうち、内側の側壁(起立部14)に係合用凸部19を設けると共に、蓋3の凹部41のうち、内側の側壁(起立部35)に係合用凹部42を設けるようにしているが、図4(b)に示す如く、係合用凸部19''や係合用凹部42''を外側の側壁に設けるようにしてもよい。   Moreover, in the said embodiment, while providing the convex part 19 for an engagement in the inner side wall (stand part 14) among the convex parts 18a of the container main body 1, the inner side wall (stand part) among the recessed parts 41 of the lid | cover 3 is provided. 35), the engaging recess 42 '' may be provided on the outer side wall as shown in FIG. 4B.

また、上記実施形態においては、容器本体1の垂下部16を周側枠2の途中箇所まで垂下させ、該周側枠2の内壁に設けたスリット21に固定するようにしているが、図4(c)に示す如く、垂下部16’を周側枠2の下面にまで延ばし、垂下部16’の先の取付部17’を周側枠2の下面に熱融着等の固着手段で取り付けるようにしてもよい。   Moreover, in the said embodiment, although the hanging part 16 of the container main body 1 is suspended to the middle part of the circumferential frame 2, it is made to fix to the slit 21 provided in the inner wall of this circumferential frame 2, but FIG. As shown in (c), the hanging part 16 'is extended to the lower surface of the circumferential frame 2, and the previous mounting portion 17' of the hanging part 16 'is attached to the lower surface of the circumferential frame 2 by fixing means such as heat fusion. You may do it.

また、上記実施形態においては、係合用凸部19を備える容器本体1の凸部18aと、係合用凹部42を備える蓋3の凹部41とを嵌合させるようにしているが、凸部や凹部の構造はこれに限定されるものではない。例えば、図5に示す如く、係合用凸部や係合用凹部を設けることなく、基端側が幅狭(先端側が幅広)となる凸部18a’及び凹部41’によって内外嵌合するようにしてもよい。尚、同図(a)に示すものは、凸部18a’及び凹部41’のそれぞれ外側の側壁を傾斜させることにより、凸部18a’及び凹部41’の基端側を幅狭にする例であり、同図(b)に示すものは、凸部18a’及び凹部41’のそれぞれ内側の側壁を傾斜させることにより、凸部18a’及び凹部41’の基端側を幅狭にする例である。   Moreover, in the said embodiment, although the convex part 18a of the container main body 1 provided with the convex part 19 for engagement and the concave part 41 of the lid | cover 3 provided with the concave part 42 for engagement are fitted, a convex part and a recessed part are used. However, the structure is not limited to this. For example, as shown in FIG. 5, the inner and outer fitting may be performed by the convex portion 18 a ′ and the concave portion 41 ′ in which the proximal end side is narrow (the distal end side is wide) without providing the engaging convex portion and the engaging concave portion. Good. In addition, what is shown to the figure (a) is an example which narrows the base end side of convex part 18a 'and concave part 41' by inclining the outer side wall of convex part 18a 'and concave part 41', respectively. The example shown in FIG. 5B is an example in which the proximal side of the convex portion 18a ′ and the concave portion 41 ′ is narrowed by inclining the inner side walls of the convex portion 18a ′ and the concave portion 41 ′. is there.
