Abstract

L'invention porte sur un corps de boîte assemblable formant un corps de boîte lorsqu'on assemble trois feuilles au moins de plaques latérales (1) constituant ensemble les parois latérales du corps de boîte, un élément de fond (5) et un élément de couvercle (10), de manière à faciliter le pliage lors du démontage du corps de boîte. Chacune des plaques latérales (1) est munie d'une colonne (2) formant un angle sur son arête, et d'une colonne engagée (3) de manière à ce que deux faces au moins puissent être engagées dans la surface interne de la colonne au niveau de l'arête opposée. La colonne (2) et la colonne engagée (3) de chaque plaque latérale (1) sont engagées l'une dans l'autre, permettant ainsi de former la paroi latérale. L'élément de fond (5) et l'élément de couvercle (10) sont munis d'une partie adaptée (6) dans laquelle la colonne (2) angulaire et la colonne engagée (3) viennent s'encastrer. La colonne (2) et la colonne engagée (3) sont disposées perpendiculairement à l'élément de fond (5) et à l'élément de couvercle (10). Ainsi, lors du démontage, les plaques latérales (1) déboîtées de l'élément de fond et de l'élément de couverture peuvent être disposée l'une sur l'autre entre l'élément de fond et l'élément de couvercle (10).
