    • A box folded from a box blank. The box blank has a nominally planar bottom member and four nominally planar sidewall members. The sidewall members are disposed in a cruciform array. Each of said members has an edge. Respective edges of the bottom member and sidewall members are adjacent to each other in pairs, and are laterally spaced apart from one another along a respective fold axis. A strap hinge is respective to each pair of edges, joining the members together whereby to permit rotation of the members relative to one another along the fold axis. A tooth is formed on one of the members and a recess is formed in the other of the members, the tooth and recess each having a restraint face which when engaged by the other restrains the member from lateral translational separation normal to the fold axis along the plane of one of the members. The box blank is preferably made of molded plastic and can be formed in a single piece.
    • 一个盒子从一个盒子里折叠起来。 盒坯具有标称平面的底部构件和四个标称平面的侧壁构件。 侧壁构件设置在十字形阵列中。 每个所述构件具有边缘。 底部构件和侧壁构件的相应边缘成对地彼此相邻,并且沿着相应的折叠轴线彼此横向间隔开。 带状铰链分别对应于每对边缘,将构件连接在一起,从而允许构件沿着折叠轴线相对于彼此旋转。 一个齿形成在其中一个构件上,并且在另一个构件中形成凹部,所述齿和凹槽各自具有约束面,当约束面接合时,所述齿和凹部沿着所述约束面紧固在垂直于折叠轴线的横向平移分离 其中一名成员的飞机。 盒子坯料优选由模制塑料制成,并且可以形成为单件。
