Abstract
Abstract A stackable transport and storage container molded integrally and unitarily from a synthetic resin, has a plurality of sidewalls defining corners between them. Each of the sidewalls is formed unitarily with a hinged strip which may be deflected inwardly and held in place therein by a snap-arrangement to support a similar container stacked thereon. When the strips are deflected outwardly, they allow the slightly tapered walls of the vessels to be interfitted or nested.

Claim 1
Independent Claim
199 words
A transport and storage container for nestling with like containers and for the stacking of like containers thereon, the container comprising a bottom and a plurality of walls in slight tapered fixed relationship fixedly connected to said bottom, a plurality of pedestals hingeD to at least some of said walls and deflectable from a position in which each pedestal lies outside the horizontal outline of the container into a position wherein the pedestal projects into the outline to support a similar container stacked thereon, said walls, said bottom and said pedestals being unitarily formed from synthetic resin and said pedestals being provided at least at two diagonally opposite corners of the container, said container having a rectangular plan configuration, said pedestals each comprising at least one strip unitarily hinged to a respective wall by a thin vertical web of the synthetic resin and deflectable from a position in which the strip is generally coplanar and flush with its respective wall into a position wherein said strip extends generally transversely to its respective wall, said strips extending vertically, said walls having recesses accommodating said strips in the first-mentioned position, and means for releasably retaining each strip in its last-mentioned position.
Claim 2
Dependent Claim
199 words
A transport and storage container for nestling with like containers and for the stacking of like containers thereon, the container comprising a bottom and a plurality of walls in slight tapered fixed relationship fixedly connected to said bottom, a plurality of pedestals hingeD to at least some of said walls and deflectable from a position in which each pedestal lies outside the horizontal outline of the container into a position wherein the pedestal projects into the outline to support a similar container stacked thereon, said walls, said bottom and said pedestals being unitarily formed from synthetic resin and said pedestals being provided at least at two diagonally opposite corners of the container, said container having a rectangular plan configuration, said pedestals each comprising at least one strip unitarily hinged to a respective wall by a thin vertical web of the synthetic resin and deflectable from a position in which the strip is generally coplanar and flush with its respective wall into a position wherein said strip extends generally transversely to its respective wall, said strips extending vertically, said walls having recesses accommodating said strips in the first-mentioned position, and means for releasably retaining each strip in its last-mentioned position.
Claim 3
Dependent Claim
54 words
The container defined in claim 1 wherein said means for retaining said strip in its last-mentioned position comprises a stud crossed by the respective strip upon its displacement from one of its positions to the other of its positions with relative deflection of the strip and stud whereby said stud thereafter intercepts said strip.
Claim 4
Dependent Claim
24 words
The container defined in claim 2 wherein said studs are provided on said bottom for engagement with the strips of a container stacked therebelow.
Claim 5
Dependent Claim
