Abstract

Selon l'invention, chaque face d'un ensemble de faces latérales (12a, 12b) qui se font face parmi les quatre faces latérales (12a à 12d) d'un récipient de stockage est pourvue d'une région comprenant deux régions trapézoïdales isocèles (14a, 14b), pour lesquelles les bords supérieur et inférieur de la face latérale (12a, 12b) servent de premiers côtés respectifs et qui partagent un second côté entre les premiers côtés, les premiers côtés étant plus longs que le second côté. Ladite région comprenant les deux régions trapézoïdales isocèles est plus dure que des régions triangulaires (16a, 16b) qui sont renfermées par les côtés des régions trapézoïdales isocèles (14a, 14b) et les bords qui relient les faces latérales (12a, 12b) aux faces latérales (12c, 12d) ; et est conçue de manière à pouvoir se replier au niveau du second côté.
