【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上記の保形リブ５５、５６は、軽い垂直荷重を支持するにはよ いが、より大きな荷重若しくは斜め荷重或いは蓋への横方向の応力が加わるなど した場合には、図６に示すように、簡単に保形リブ５５、５６同士の当接がずれ て外れてしまうため、容器がつぶれ内容物Ａが破損するおそれがあった。 However, although the shape-retaining ribs 55 and 56 described above are better for supporting a light vertical load, they are shown in FIG. 6 when a larger load, an oblique load, or a lateral stress is applied to the lid. As described above, since the shape-retaining ribs 55 and 56 are easily disengaged from each other, the container may be crushed and the contents A may be damaged.

【０００４】 そこで、本考案は、かかる問題点に鑑みて、内容物を確実に保護するためにい ずれの方向からの押圧力に対しても保形性を維持することができる合成樹脂容器 を提供せんとする。Therefore, in view of such problems, the present invention provides a synthetic resin container capable of maintaining the shape retention property against the pressing force from any direction in order to reliably protect the contents.

【考案の実施の形態】[Embodiment of device]

以下、本考案の食品用容器の一実施例を図面によって説明する。 合成樹脂容器１は、図１に示すように、適宜合成樹脂シートを圧空、真空成形 等の熱成形してなる容器本体２及び蓋体３とからなり、これら容器本体２及び蓋 体３の一側縁部はヒンジ４で連結し、一体に形成してある。 An embodiment of the food container of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a synthetic resin container 1 is composed of a container body 2 and a lid body 3 which are formed by thermoforming a synthetic resin sheet by pressure molding, vacuum molding or the like as appropriate. The side edge portions are connected by a hinge 4 and are integrally formed.

【０００８】 容器本体２は、図１及び２に示すように、底面部５、周側面部６、この周側面 部６の上縁を水平外側に折曲してなる若干巾の鍔部７、この鍔部７の外側を下方 に折り返してなる外側部８、及び外側部８の下縁を更に水平外側に折曲してなる 水平部９を順次形成する一方、前記底面部５及び周側面部６に囲まれた容器収納 部内には、周側面部６のヒンジ側面から対向側面方向に長く伸びた狭巾の仕切状 の保形リブ１０、１０を適宜間隔をおいて並設してある。As shown in FIGS. 1 and 2, the container body 2 includes a bottom surface portion 5, a peripheral side surface portion 6, and a flange portion 7 of a slightly width formed by bending an upper edge of the peripheral side surface portion 6 horizontally outward. An outer side portion 8 formed by folding back the outer side of the collar portion 7 and a horizontal portion 9 formed by further bending the lower edge of the outer side portion 8 to the horizontal outer side are sequentially formed, while the bottom surface portion 5 and the peripheral side surface portion are formed. In the container housing portion surrounded by 6, there are narrow shape retaining ribs 10 and 10 extending in a direction from the hinge side surface of the peripheral side surface portion 6 to the opposite side surface side by side at appropriate intervals.

【０００９】 この保形リブ１０は、図２に示すように、底面部５から上記水平部９と同じ高 さに***させ、先端縁部は巾狭かつ若干の凸曲面状として係合部１１を形成して ある。As shown in FIG. 2, the shape-retaining rib 10 is raised from the bottom surface portion 5 to the same height as the horizontal portion 9, and the tip edge portion has a narrow and slightly convex curved surface shape to engage the engaging portion 11. Has been formed.

【００１０】 蓋体３は、図１及び２に示すように、天面部１２、周側面部１３、周側面部１ ３の下縁を上記本体の鍔部７に対応するように水平外側に折曲してなる鍔部１４ 、鍔部１４の外側を上記本体の外側部８に対応するように下方に折曲してなる外 側部１５、外側部１５の下縁を上記本体の水平部９に対応するように水平外側に 折曲してなる水平部１６を順次形成する一方、天面部１２及び周側面部１３に囲 まれた蓋体内には、蓋体３を容器本体２に被嵌させた状態で上記保形リブ１０と 先端縁部同士が係合するように、蓋体の周側面部１３のヒンジ側面から他側面方 向に長く伸びた狭巾の仕切状の保形リブ１７、１７を並設してある。As shown in FIGS. 1 and 2, the lid body 3 has a top surface portion 12, a peripheral side surface portion 13, and a lower edge of the peripheral side surface portion 13 folded horizontally outward so as to correspond to the collar portion 7 of the main body. The bent flange portion 14, the outer side portion 15 formed by bending the outside of the flange portion 14 downward so as to correspond to the outer portion 8 of the main body, and the lower edge of the outer portion 15 at the horizontal portion 9 of the main body. The horizontal portion 16 is formed by being bent outward in the horizontal direction so as to correspond to the above, while the lid body surrounded by the top surface portion 12 and the peripheral side surface portion 13 is fitted with the lid body 3 on the container body 2. In the closed state, the shape-retaining rib 17 has a narrow width and extends from the hinge side surface of the peripheral side surface portion 13 of the lid body toward the other side surface so that the leading edge portions are engaged with each other. 17 are arranged side by side.

【００１１】 この保形リブ１７も、上記保形リブ１０と同様に、図２に示すように、前記天 面部１２から水平部１６と同じ高さに***させ、先端縁部には本体の係合部１１ と嵌合するように保形リブ１７の長さ方向に沿って凹曲溝状の係合部１８を形成 してある。As with the shape-retaining rib 10, the shape-retaining rib 17 is also raised from the top surface portion 12 to the same height as the horizontal portion 16, and the tip edge portion of the main body is engaged with the shape-retaining rib 17, as shown in FIG. An engagement portion 18 having a concave groove shape is formed along the length direction of the shape-retaining rib 17 so as to fit with the joint portion 11.

【００１２】 合成樹脂容器１は上記構成であるから、図３に示すように、蓋体３を容器本体 ２に被嵌させて本体の水平部９に蓋体の水平部１６を当接させると、蓋体の水平 部１６と本体の水平部９とが略々面一となって係合し、同時に蓋体の係合部１８ 内に本体の係合部１１が嵌合して本体の保形リブ１０と蓋体の保形リブ１７とが 先端部同士で係合するから、合成樹脂容器１に対して水平方向、垂直上下方向及 び斜め方向などのいずれの方向からの押圧力が加わっても保形リブ１０，１７と の係合がずれることがなく、合成樹脂容器１内の内容物を確実に保護することが できる。 特に本考案の合成樹脂容器１では、本体及び蓋体の保形リブ１０、１７を長尺 に形成し、その長さに亘って両者の先端縁部同士を係合させてあるから、両者の 係合がより一層確実なものとなっている。Since the synthetic resin container 1 has the above-mentioned structure, as shown in FIG. 3, when the lid body 3 is fitted on the container body 2 and the horizontal portion 16 of the lid body is brought into contact with the horizontal portion 9 of the body. , The horizontal portion 16 of the lid body and the horizontal portion 9 of the main body are substantially flush with each other, and at the same time, the engaging portion 11 of the main body is fitted into the engaging portion 18 of the lid body to keep the main body. Since the shape ribs 10 and the shape-retaining ribs 17 of the lid engage with each other at their tip portions, a pressing force is applied to the synthetic resin container 1 from any direction such as a horizontal direction, a vertical up-down direction, and an oblique direction. Even if the shape-retaining ribs 10 and 17 are not displaced, the contents in the synthetic resin container 1 can be reliably protected. In particular, in the synthetic resin container 1 of the present invention, the shape-retaining ribs 10 and 17 of the main body and the lid are formed in a long shape, and the tip edges of both are engaged with each other over the length thereof. Engagement is more secure.

【００１３】 なお、本考案においては、本体の保形リブ１０と蓋体の保形リブ１７との係合 構造は上記実施例に限定するものではない。 例えば、図４（Ａ）に示すように、保形リブ１０の先端部を平坦面状とし、そ の先端部中央部を長さ方向に沿って突出させるようにしてもよい。また、図４（ Ｂ）に示すように、容器本体２の保形リブ１０の先端縁部にその長さ方向に沿っ て凹曲面溝状の係合部２０を形成する一方、蓋体３の保形リブ１７の先端縁部を 、上記係合部２０と嵌合するように、若干の凸曲面状として係合部２１を形成す るようにしてもよい。さらにまた、図示はしないが、本体の保形リブ１０を底面 部５から上記鍔部７と同じ高さに***させると共に、蓋体の保形リブ１７を天面 部１２から水平部１６と同じ高さに***させるようにしてもよい。In the present invention, the engagement structure between the shape-retaining rib 10 of the main body and the shape-retaining rib 17 of the lid is not limited to the above embodiment. For example, as shown in FIG. 4 (A), the tip of the shape-retaining rib 10 may be flat, and the center of the tip may be projected along the length direction. Further, as shown in FIG. 4 (B), a concave curved groove-shaped engaging portion 20 is formed along the length direction at the tip edge portion of the shape-retaining rib 10 of the container body 2, while The engagement portion 21 may be formed in a slightly convex curved shape so that the tip edge portion of the shape-retaining rib 17 fits with the engagement portion 20. Further, although not shown, the shape retaining rib 10 of the main body is raised from the bottom surface portion 5 to the same height as the collar portion 7, and the shape retaining rib 17 of the lid body is the same as the top surface portion 12 to the horizontal portion 16. You may make it raise to a height.

【００１４】 また、上記保形リブ１０及び保形リブ１７の直角方向にも保形リブ１０及び保 形リブ１７とを形成することもできる。このように形成すれば、容器の保形性を 一層高めることができる。Further, the shape-retaining ribs 10 and the shape-retaining ribs 17 can also be formed in the direction perpendicular to the shape-retaining ribs 10 and the shape-retaining ribs 17. If formed in this way, the shape retention of the container can be further enhanced.
