Abstract
A nesting rim member mountable in circumscribing composite relation to the stacking end of a walled container. The rim includes an outer vertical flange portion which tapers inward from an upper edge to a nesting ledge. An inverted U-shaped channel portion beneath the nesting ledge extends over the container sidewalls which are recessed at their corners to receive pronged corner clips, if necessary. Each clip mates with the rim member when pressed onto the container walls. A U-shaped channel orthogonally projects inward of the container. The rim member may be extruded and pieced to the container walls or molded as a continuous ring.
Claims17
A material handling container comprising:
- (a) a bottom wall and a plurality of vertical side walls;
- (b) a rim member including a first channelway which mounts over an upper edge of each of the side walls to circumscribe all of the side walls and a plurality of vertical notches let substantially through the first channelway at each of a plurality of corners between adjacent sidewalls such that the rim member may be folded to conform to the corners;
- and
- (c) means for securing said rim member to each side wall including a plurality of corner clips, wherein each corner clip mounts within said first channelway at each corner.
A material handling container comprising:
- (a) a planar sheet stock material cut and partially scored to fold into a bottom wall and a plurality of vertical side walls;
- (b) a rim member having a channelway mounting over an upper edge of each of the side walls to circumscribe all of the side walls and exhibiting an h-shape when viewed in a plane orthogonal to each side wall, wherein an interior surface of an uppermost vertical flange portion concentrically surrounds the container side walls and tapers inward to a horizontal shelf portion and whereby secured registration is promoted between stacked containers;
- (c) a plurality of corner clips, each corner clip mounting within the first channelway of said rim member intermediate the upper edges of a corner formed between adjacent side walls and wherein each clip includes a plurality of portions having a span greater than the span between sidewall contacting surfaces of the channelway and which portions embed into said channelway upon mounting the rim member over the sidewalls;
- (d) means for securing said rim member to each side wall;
- and
- (e) handle means for hand grasping said container.
A stackable material handling container comprising:
- (a) a bottom wall and a plurality of vertical side walls;
- (b) a rim member including a channelway mounting over an upper edge of each of the side walls to circumscribe all of the side walls and having a horizontal shelf portion overlying said channelway and a vertical flange portion rising from said shelf portion and wherein a surface of said vertical flange portion tapers inward from an overlying end to the horizontal shelf portion and such that the bottom of a second container is guided into stacked registration with the horizontal shelf portion by the tapered surface;
- (c) means for securing said rim member to each side wall;
- and
- (d) handle means for grasping the container.
