  • Patent number: 4319685
    Abstract: The crate is capable of being fitted in other crates to form a stack. The crate comprises an upper girdle portion, an apertured buttom portion, and lateral walls and inner partition walls formed by inclined arms which may form a vertical geometric projection in the empty spaces of the bottom portion in the plane of the latter. These arms form surfaces of pyramids for maintaining and separating the bottles or the like. The inclined arms are capable of sliding on those of another crate when a plurality of crates are fitted together. At least a part of the apices of the inclined arms is capable of coinciding of solid parts of the apertured bottom portion of an identical crate which is placed in a different orientation above the first crate.
