Abstract

A portable, open top utility tote container constructed and shaped from a lightweight yet durable, semirigid, corrugated plastic material used to store or transport an unlimited variety of household or industrial items. The receptacle portion of the container is formed from a single sheet of material, cut, scored into panels, and folded to the shape of a tapered rectangular box. End panels and side flaps are folded over a reinforcing rim which runs around the top perimeter of the container, the end panels being cut out to form hand grips at opposing ends of the container, and the side flaps creating a firm stacking shoulder upon which the container may rest when stacked on other similar containers. The single sheet of material from which the receptable is formed, when extended in a single plane, has a configuration confined by a rectangle whose length and width are the distances between the outer edges of the end panels and side flaps.

Claims

1. A material handling container comprising:

a receptacle portion formed from a single sheet of semirigid material which is cut, scored, and folded to form a generally rectangular base platform from which a pair of substantially upright opposed side walls and a pair of substantially upright opposed end walls extend, said side and end walls being hingedly connected to said base platform and defining an open top when folded to a generally upright position;

a pair of end panels at each end of said receptacle portion hingedly connected to the opposite ends of each of said side walls along generally vertically extending score line connections, each pair of said end panels being folded over the adjacent one of said end walls in abutting, parallel relation therewith;

a pair of foldover panels at each end of said receptacle portion hingedly connected to the upper ends of each of said end panels along score lines traversing the upper ends of each of said end panels, said foldover panels being folded downwardly and inwardly thereover with the surface of said foldover panels substantially parallel to the surface of said end panels and secured by attachment means to said end walls therebetween;

a pair of outer flaps defined by score lines extending lengthwise of said side walls adjacent the top extremities thereof and hingedly connected thereto, said outer flaps being folded downwardly to form upper stacking shoulders defined by said score lines along the top edges of said side walls; and

a pair of inner flaps defined by score lines extending lengthwise of the outer edges of said outer flaps and substantially parallel therewith and hingedly connected thereto, each said inner flap being folded upward between the outer flap to which said inner flap is connected and the adjacent side wall, to form lower stacking shoulders, whereby the lower stacking shoulders rest on said upper stacking shoulders when a plurality of said utility tote containers are nested one inside the other.

2. The utility tote container of claim 1 further comprising:

a plurality of completely cutaway segments in each of said end panels and said foldover panels positioned adjacently along the top edge of said end panels and said foldover panels, said cutaway segments cooperating to form a pair of hand grip openings located at opposing ends of said receptacle portion when said side walls, said end panels, and said foldover panels are folded in a generally upright configuration;

a pair of side rim pockets, bordered and defined by the top of said side walls, said outer flaps, and said inner flaps;

a pair of end rim pockets, bordered and defined by the top of said walls, and between said end panels and foldover panels;

a rigid reinforcing rim of generally rectangular shape contained within said side rim pockets and said end rim pockets, and extending around the top of said container; and

a pair of hand grips on opposite ends of said container formed by intermediate portions of said reinforcing rim disposed across the top of said hand grip openings.

3. A container as defined in claim 2 wherein:

said means of attaching said end panels to said end walls, and said foldover panels to said end walls, and said inner flaps to said side walls, is at least one sonic weld.

4. A container as defined in claim 3 wherein:

said outer flaps define at least one aperture which extends through said outer flap in relative spatial proximity to and communicating with said sonic welds.

5. A container as defined in claim 4 wherein:

said sheet of semirigid material is formed from corrugated polyethylene.

6. A container as defined in claim 5 wherein:

the number of score lines defining said upper stacking shoulders along the top edge of each said side wall is two.

7. A container as defined in claim 6 wherein:

said single sheet of semirigid material has a configuration when extended in a single plane so as to be confined by a rectangle whose length is no greater than the distance between the outer edges of said inner side flaps and whose width is no greater than the distance between the outer edges of said end walls.
