Abstract

Abstract A collapsible tray constructed from a single blank of fiberboard material folded and formed to provide an open top tray having a relatively short, front end wall providing a front access opening, and reinforced by a rigid rim extending around the entire, inner periphery of the tray with the side legs of the rim extending along the side walls of the tray in a downwardly and forwardly inclined position. The front end of the inclined rim extends across the top of the short, front end wall of the tray, and the rear end of the rim is supported at a higher elevation coinciding with the top of the rear end wall of the tray; and the side legs of the rim taper inwardly towards each other towards the front of the tray to provide for the snug positioning of the rim along the entire length of the inclined side walls of the tray.

Claim 7
Dependent Claim 258 words
A collapsible tray formed from a single blank of cut and scored paperboard material comprising: a bottom wall, a pair of opposed, upright side walls inclined upwardly and outwardly from fold line connections with said bottom wall, and a pair of opposed, upright end walls, the upper edges of said side and end walls defining an open top of said tray, and the one of said upright end walls at the front of said tray being shorter than the opposite, rear one of said end walls; a pair of inwardly folded, upright flaps at each end of said tray; and a rigid, four-sided, reinforcing member supported within said tray on top of said inwardly folded flaps in an inclined position with one end supported adjacent the top of the rear end wall of said tray, and the opposite end of said reinforcing member being supported adjacent the top of said front, shorter end wall, said reinforcing member having side legs which taper inwardly towards each other in a direction from the rear towards the front of said tray, whereby the front end of said reinforcing member will be narrower than the rear end thereof and will be of a predetermined width such that said reinforcing member will fit snugly between said opposed, inclined side walls of said tray along substantially the entire length thereof with the front end of said reinforcing member being supported at an elevation below the top edges of said side walls where the width of said tray is less than at the top thereof.
