Description

本発明は、主として、各種惣菜、ごはん類、麺類、菓子類等の食品を収納するための食品包装用容器に関する。 TECHNICAL FIELD The present invention mainly relates to a food packaging container for storing foods such as various side dishes, rice, noodles, confectionery and the like.

このような食品包装用容器として、容器本体と枠体を組み合わせたものが広く用いられている。
例えば、本出願の発明者は、特許文献１（特許第３９６５３２１号公報）に記載されているように、直方体状とした枠体(1)の上から容器本体(10)を落とし込み、容器本体(10)の側壁部(12)に設けられた係合凸部(15)と枠体(1)の上方内面に設けられた係合凹部(8)とを係合させて、容器本体(10)と枠体(1)とが容易に分離しないようにした食品収納用簡易容器を提案している（特に、段落００２３～００２５及び図９を参照）。 As such a food packaging container, a combination of a container body and a frame body is widely used.
For example, as described in Patent Document 1 (Japanese Patent No. 3965321), the inventor of the present application drops the container body (10) from above a rectangular parallelepiped frame (1), and the container body ( 10) is engaged with an engagement projection (15) provided on the side wall (12) of the container body (10) with an engagement recess (8) provided on the upper inner surface of the frame (1), and the container body (10) is and the frame body (1) are proposed to prevent easy separation of the food storage container (particularly, see paragraphs 0023 to 0025 and FIG. 9).

また、特許文献２（実開昭５５－１８４４４号公報）には、容器(1)の周縁に内側上段リップ(2)及び外側上段リップ(3)を設け、内側上段リップ(2)を熱収縮性フィルム(6)の接着面とした密封容器が開示されている（特に、請求項１及び第１図を参照）。 In Patent Document 2 (Japanese Utility Model Laid-Open No. 55-18444), an inner upper lip (2) and an outer upper lip (3) are provided on the periphery of the container (1), and the inner upper lip (2) is heat-shrunk. A sealed container with an adhesive surface of the adhesive film (6) is disclosed (see in particular claim 1 and figure 1).

そして、本出願の発明者は、食品収納用簡易容器を密封容器とするため、食品収納用簡易容器の周縁部の内側に、特許文献２のように段部を設け、段部の上面に密封用フィルムを固着できるようにする改良を試みた。
しかし、特許文献１の食品収納用簡易容器に段部を設けた場合、容器本体(10)と枠体(1)とが容易に分離しないようにするためには、段部を深くして段部の外側壁に係合凸部(15)を設けるととともに、係合凸部(15)の上部に係合凹部(8)と係合できるようにするためのスペースを確保する必要があり、容器高さの割に食品収容部の容積が小さくなってしまうことが分かった。
なお、枠体(1)の係合凹部(8)を枠体(1)の上縁近くに設ければ、確保すべきスペースが小さくなり、段部をある程度は浅くできるが、そうした場合、枠体(1)の上縁付近の内側が壊れ易くなるので、係合凹部(8)と係合凸部(15)とをしっかり係合させられなくなるトラブルが発生し易い。 In order to make the simple food storage container a sealed container, the inventor of the present application provided a stepped portion inside the peripheral edge portion of the simple food storage container as in Patent Document 2, and sealed the upper surface of the stepped portion. An attempt was made to improve the film so that it can be fixed.
However, when the simple food storage container of Patent Document 1 is provided with a stepped portion, the stepped portion must be deepened in order to prevent the container body (10) and the frame (1) from being easily separated. It is necessary to provide an engagement projection (15) on the outer wall of the part and secure a space above the engagement projection (15) so that it can be engaged with the engagement recess (8). It was found that the volume of the food storage portion becomes small for the height of the container.
If the engaging recess (8) of the frame (1) is provided near the upper edge of the frame (1), the space to be secured becomes smaller and the stepped portion can be made shallower to some extent. Since the inside near the upper edge of the body (1) becomes fragile, it is easy to cause troubles in which the engagement concave portion (8) and the engagement convex portion (15) cannot be firmly engaged.
