Abstract

Abstract A container consisting of cooperating top and bottom trays. Each tray has opposed upstanding end walls and opposed upstanding side walls. The height of the end walls of each tray are greater than the height of the side walls of the same tray. In order to assemble the two trays together to form a container, the two trays are inverted relative to each other so that one tray forms a top and the other tray forms a bottom. The two inverted trays are rotated 90° so that the taller end walls of one tray cooperates and telescopes over the shorter side walls of the other tray to form a container.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 279 words
A container comprising a pair of cooperating, identical trays, each tray comprising a main body portion, opposed side walls being of uniform height and together forming an octagon and extending upwardly from the main body portion, opposed ends walls extending upwardly from said main body portion, said end walls being approximately twice as tall as said side walls, said trays being inverted and rotated 90° relative to each other so that the taller end walls of one tray are telescoped over the shorter side walls of the other tray with the end walls completely covering the side walls to produce a seamless container, said end walls and said side walls being hingedly connected to said main body portion and each side wall comprising (1) a central portion hingedly attached to said main body along a side edge thereof and (2) outer portions angularly attached to opposite ends of said central portion along first fold lines and (3) end flaps angularly attached to the opposite ends of said outer portions along second fold lines parallel to said first fold lines, each end flap being attached to the inner face of the adjacent end wall completely inwardly from the end edges of said end wall, each of said end flaps being of a length substantially less than one-half of the width of an end wall wherein an outer edge of the side wall central portion of one tray will abut and be supported on an outer edge of the end flap of the other tray when said trays are inverted and rotated 90° relative to each other and one of said trays seated on the other to form a closed container.
