可堆叠的板条箱的可折叠的柔性材料，其包括在角部凸耳堆叠并且可以被放置在位于下方的板条箱，连接到四个角由引脚的两个区间的堆叠凸耳的 通过折叠线折叠并且在它们各自的另一侧连接到相应的侧壁，以便在堆叠（即在使用中）形成具有板条箱的角部的方形空心支撑件的同时，以及 真空状态下，以能够通过从所述箱的内部对角施加的侧向压力，从而克服了死点中心位置，以本身在之间的板条箱，所述折叠线（10.2）的角位置再次 与对应角落的边缘广泛相符的凸耳部分。

Stackable crate foldable flexible material, comprising stacking lugs in the corners and which can be placed on the crate located below, of the stacking lugs of the four corners being constituted by two sections of pins connected to the another by a fold line and connected at their other respective sides of the corresponding side wall so as to form when stacking (i.e. service) with a square hollow support the corners of the crate, and the vacuum state, to be able, thanks to a lateral pressure exerted diagonally from the inside of the crate, thus overcoming a dead center position, to position itself again at the corners of the crate, the fold line (10.2) between the dewclaws sections largely coincident with the edge of the corresponding corner.
