A disposable cardboard crate for transporting and storing goods, particularly, containers of milk. The crate is a rectangular open top container and opposed end walls (25) extend above the height of the other walls (26). The end walls (25) are each folded back on themselves at the top to form a triangular box structure or girder which extends across the end and provides a horizontal ledge (24) projecting inwardly of the crate. The ledge (24) is at a height very slightly above the height of the other walls (26). The girder contributes substantially to the strength of the crate. The end walls (25) are inclined upwardly and outwardly slightly to allow the base (20) of a further crate in a stack to fit between upwardly extending portions (27) and rest on the ledges (24). The end walls have a width (X) at the top slightly less than the width (Y) at the bottom such that the base (20) of a crate overlies the other walls (26) of the crate immediately therebelow in a stack thereby contributing to the stacking strength. A blank for forming the crate is also claimed.

A blank erectable into a crate, said blank including a first panel for forming a base of the crate and a plurality of further panels which extend from said first panel for folding to form generally upright peripheral walls of the crate, characterized in that, said further panels include an opposite pair of end wall panels providing end walls for the crate, and each end wall panel includes a first portion and an extended portion which is foldable relative to the first portion for forming a ledge which projects perpendicularly from said end wall to project inwardly of the crate and an extension distal to said first panel to form an upward extension of its respective end wall in the crate, said ledges being between said upward extensions and said first panel in order to lie below said upward extensions and provide support for the base of a like crate when stacked thereon, said end wall panels having means for inclining the end walls of the crate upwardly and outwardly slightly to allow the base of said like crate to fit between said upward extensions when said like crate is stacked thereon thus preventing relative horizontal sliding movement between the crates in a first direction, and said end wall panels have a width dimension at an end distal to the first panel which is less than the width dimension of said end wall panels at an end adjacent to said first panel, whereby said crate is tapered inwardly and upwardly slightly when viewed from an end, whereby said base of said like crate overlies the upper edges of the other said peripheral walls of the crate immediately therebelow when said crates are stacked such that the other said peripheral walls provide support to the crate above, when said ledge is caused to deflect due to the weight thereon.
