Cardboard packaging for storage and transport, especially of small parts forming flow of materials for automobile manufacture, folds to rigid tapering box construction with good stackability

摘要

Opposite sidewalls (2, 3) have an inner side (4), upper longer-, and lower shorter edges (5, 6). There are two rectangular stacking and reinforcing components (19) of multi-layer corrugated cardboard with an upper edge (20). Each of these (19) is adhered to an inner side of one of the sidewalls so that the upper edge (20) is located below that (5) of the associated sidewall. Two second opposite sidewalls (11, 12) have upper and lower edges (14, 15). The difference between their (14, 15) lengths is less than the sum of the thicknesses of the two stacking- and reinforcing components (19).
