PACKAGING CONTAINER

To provide a packaging container that allows the insertion pieces to be easily inserted into the insertion hole and to be hard to come off.SOLUTION: A packaging container 1 includes: a pair of inner folded walls 13 connected to a pair of first side walls 11 and having insertion holes 22; a pair of pier walls 16 connected to a pair of second side walls 12 and having auxiliary fold lines L8; and a pair of insertion pieces 17 connected to both ends of the pier walls 16 and folded along insertion fold lines L9 and inserted into the pair of insertion holes 22. The insertion pieces 17 are formed to be longer than the total length of the insertion holes 22 by having leading convex portions 23, and after the inner folded wall 13 (frame 20) is folded, the pier wall 16 is bent and folded forward at the auxiliary fold line L8, and some of the insertion pieces 17 are inserted into the insertion holes 22. And then the pier wall 16 folded at the auxiliary fold line L8 is extended and laminated on the frame 20, causing the insertion piece 17 to insert the leading convex portion 23 thereof into the back side of the frame 20, which is located closer to the free end side of the pier wall 16 rather than to the insertion hole 22.SELECTED DRAWING: Figure 5 【課題】 差込片を差込穴に差し込みやすく抜け難くすることができる包装容器を提供する。【解決手段】包装容器１は、一対の第１側壁１１に連設され、差込穴２２を有する一対の内折返し壁１３と、一対の第２側壁１２に連設され、補助折線Ｌ８を有する一対の桟壁１６と、桟壁１６の両側端に連設され、差込折線Ｌ９に沿って折り曲げられて一対の差込穴２２に差し込まれる一対の差込片１７と、を備え、差込片１７は先端凸部２３を有することで差込穴２２の全長よりも長い寸法に形成され、内折返し壁１３（額縁部２０）が折り曲げられた後、桟壁１６が折り曲げられ且つ補助折線Ｌ８で正折りされ、差込片１７の一部が差込穴２２に差し込まれ、続いて、補助折線Ｌ８で屈曲した桟壁１６が伸ばされながら額縁部２０に積層されることで、差込片１７は先端凸部２３を差込穴２２よりも桟壁１６の自由端側に位置する額縁部２０の裏側に潜り込ませる。【選択図】図５
