Abstract

Le but de la présente invention est d'obtenir un récipient en papier facilement pliable à plat ayant une partie supérieure dans laquelle une surface supérieure est une surface inclinée. Dans un récipient en papier ayant une surface inclinée au niveau d'une partie supérieure de celui-ci, des panneaux de surface latérale gauche et droite de partie corps ont des premières lignes de pliage inclinées de pliage (40 et 41) qui forment des triangles C symétriques par points avec des triangles A formés dans des panneaux de surface latérale (17 et 18) à l'aide de points centraux M de secondes lignes de pliage latérales de partie supérieure (15 et 16) en tant que centres symétriques, et des secondes lignes de pliage inclinées de pliage (42 et 43) qui forment des triangles D symétriques en ligne avec des triangles B formés dans des panneaux de surface inférieure interne (26 et 27) à l'aide de secondes lignes de pliage horizontales de partie inférieure (24 et 25) en tant qu'axes symétriques. Un panneau de partie corps a des lignes de pliage verticales de partie corps (44 et 45) qui relient des sommets P3 des triangles C et des sommets P4 des triangles D les uns aux autres, une première ligne de pliage horizontale de pliage (46) qui relie les sommets P3 des triangles C les uns aux autres, et une seconde ligne de pliage horizontale de pliage (47) qui relie les sommets P4 des triangles D les uns aux autres.
