Abstract

A five-piece container for items, such as bottles, comprises a bottom piece, a pair of side pieces of identical height and a pair of end pieces also of identical height; each side edge and each end edge of the bottom piece display a series of planar surfaces interspaced with a series of recessed areas in which is defined a hinge that engagedly receives a C-shaped extension formed at the lower edge of each side piece and of each end piece so that the side and end pieces may be mounted to the bottom piece through a snap engagement. The end pieces and the side pieces can be moved between an outward foldback position and an erected position; however, an inward folded position cannot be effected due to the configuration of the lower edge of the side pieces and of the end pieces and that of the edges of the bottom piece. The folding configuration is useful for containers that have walls higher than the width of the bottom thus preventing the walls from being folded inside.

Dependent claims

A container comprising:

a bottom piece formed of plastic, and having a top surface defining a first plane, an opposite bottom surface defining a second plane, a first pair of opposite edges, and a second pair of opposite edges, each of said edges including a plurality of parallel axially spaced apart cylindrical plastic hinge portions, said hinge portions respectively defining hinge axes, the hinge axes of all of said edges lying in a common plane between said first and second planes, each said edge further including a plurality of parallel, spaced apart ledge surfaces extending in a direction perpendicular to an axis defined by the hinge portions of the same edge, said bottom piece including, on said top surface thereof, a series of raised profiles and, on said bottom surface thereof, a series of recessed areas in vertical complementary alignment with said series of raised profiles;
a pair of plastic side pieces, each side piece having a lower plastic edge including C-shaped extensions closely resiliently receiving the hinge portions of one of the edges of the bottom piece for pivotal movement between an outward foldback position, wherein said side piece is generally coplanar with said bottom piece, and an erected position, said C-shaped extensions impeding movement of the side pieces in a direction radially away from the hinge portions except for removal of said side pieces from said bottom piece, said lower edge of respective side pieces including a series of spaced apart flat faces which are operative to engage at least some of the ledge surfaces of the bottom piece to prevent said side pieces from pivoting inwardly toward the opposite side piece to an inwardly folded position;
a pair of plastic end pieces, each end piece having a lower plastic edge including C-shaped extensions closely resiliently receiving the hinge portions of one of the edges of the bottom piece for pivotal movement between an outward foldback position, wherein said end piece is generally coplanar with said bottom piece, and an erected position, said C-shaped extensions impeding movement of the end pieces in a direction radially away from the hinge portions except for removal of said end pieces from said bottom piece, said lower edge of respective end pieces including a series of spaced apart flat faces which are operative to engage ledge surfaces of the bottom piece to prevent said end pieces from pivoting inwardly toward the opposite side piece to an inwardly folded position;
and
resiliently interengaging plastic surfaces on said side pieces and on said end pieces for selectively locking said side pieces to said end pieces to retain said side pieces and end pieces in the erected position wherein, when said side pieces, and end pieces are in the erected position, said side pieces and end pieces have a uniform height greater than the distance between opposite edges of one of the pairs of opposite edges of the bottom piece.

2 more elements

A five-piece container for carrying items, such as bottles, comprising:

a bottom piece formed of plastics material, said bottom piece having a top surface defining a first plane, a bottom surface defining a second plane, a pair of opposite side edges, a pair of opposite end edges;
said end edges having a given length;
a pair of side pieces of identical height formed of plastics material, each side piece having a lower edge;
said height being greater than said length of said end edges of said bottom piece;
and
a pair of end pieces of identical height formed of plastics material, each end piece having a lower edge;
each said side edge and each said end edge of said bottom piece displaying a series of planar surfaces, interspaced by a series of recessed areas, and a horizontally extending integrally formed hinge traversing each said recessed area and defining an axis lying in a plane between said first and second planes;
each said lower edge of said side pieces and of said end pieces displaying a series of flat faces and a series of horizontally spaced extensions, each defining a C-shaped profile, between said faces;
said extensions being so disposed along each said lower edge as to be received within a corresponding one of said recessed areas for assembly of a side piece to said bottom piece;
said profiles being configured to enable snap engagement and disengagement of said extensions with and from said hinges and to allow said side pieces to be moved between an outward foldback position and an erected position;
said flat faces of said side pieces and of said end pieces resting on said planar surfaces of said bottom piece in said erected position thereby preventing said side pieces and said end pieces to move inwardly to an inwardly folded position.
