Abstract
Abstract A blank or tray formed therefrom and including a bottom wall and side walls with the end walls formed by an end panel having a slit therein and by end flaps connected to the side walls and provided with upper and lower tabs. The structure of each flap is such that it may be folded along a diagonal fold-line to permit the upper tab to be moved into a position to be slid through the slot in the adjacent end panel and then the flap forced into a straightened position with the bottom tab received in a hole in the bottom wall. If desired, a lid assembly may be provided, the lid assembly having tabs thereon adapted to be received within extensions of the slit through which the top tab is received.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
286 words
A blank forming a tray, comprising a bottom wall, end walls foldably connected one to each end of said bottom by a fold-line, at least one slit in each of said end wall, at least one slot in said bottom wall adjacent to each of said fold-lines, a pair of side walls one foldably connected to each side of said bottom wall by a fold-line substantially perpendicular to said fold-lines connecting said end walls to said bottom wall, end flaps foldably connected one to each end of each of said side walls by a fold-line substantially perpendicular to the fold-line connection between said side wall and said bottom wall, each of said end flaps terminating in a free end and being provided with an upper tab formed in said flap and a bottom tap projecting down from said flap and a diagonal fold line extending across said flap from said free edge toward the junction of the fold-line connection between said flap and said side wall to which it is attached and said fold-line connecting said side wall to which is attached to said bottom wall, said, at least one slit in each said end wall and said diagonal fold-line in each said flap being arranged so that each said end flap may be folded along said diagonal fold-line to permit movement of each said end flap into a position wherein the top edge and upper flap may be received in the adjacent of said slits in said end wall, when said end flap is in face to face relationship with its adjacent end wall, said lower tab being positioned to co-operate with the adjacent said slot in said bottom wall when said tray is erected.
Claim 2
Dependent Claim
286 words
A blank forming a tray, comprising a bottom wall, end walls foldably connected one to each end of said bottom by a fold-line, at least one slit in each of said end wall, at least one slot in said bottom wall adjacent to each of said fold-lines, a pair of side walls one foldably connected to each side of said bottom wall by a fold-line substantially perpendicular to said fold-lines connecting said end walls to said bottom wall, end flaps foldably connected one to each end of each of said side walls by a fold-line substantially perpendicular to the fold-line connection between said side wall and said bottom wall, each of said end flaps terminating in a free end and being provided with an upper tab formed in said flap and a bottom tap projecting down from said flap and a diagonal fold line extending across said flap from said free edge toward the junction of the fold-line connection between said flap and said side wall to which it is attached and said fold-line connecting said side wall to which is attached to said bottom wall, said, at least one slit in each said end wall and said diagonal fold-line in each said flap being arranged so that each said end flap may be folded along said diagonal fold-line to permit movement of each said end flap into a position wherein the top edge and upper flap may be received in the adjacent of said slits in said end wall, when said end flap is in face to face relationship with its adjacent end wall, said lower tab being positioned to co-operate with the adjacent said slot in said bottom wall when said tray is erected.
Claim 3
Dependent Claim
41 words
A blank as defined in claim 1 wherein said top edge of each of said top tabs is substantially aligned with the top edges of said side wall to which the flap which said top tab is formed is directly connected.
Claim 4
Dependent Claim
57 words
A blank a defined in claim 1 wherein the distance between each said slit and said fold-line connecting the end wall in which said slit is formed to said bottom wall is substantially equal to the distance between the bottom of said upper tab and said bottom wall when said blank is erected to form a tray.
Claim 5
Dependent Claim
200 words
A tray comprising a bottom wall, an end wall connected to each end of said bottom wall by a fold-line and extending substantially perpendicular to said bottom wall, a slit in each of said end wall at least one slot in said bottom wall adjacent to each of said fold-lines, a pair of side walls foldably connected one to each side of said bottom wall and extending substantially perpendicular to said bottom and end wall, end flaps foldably connected one to each end of each said side wall and extending substantially perpendicular to said side walls said end flaps being positioned between said end wall, each of said end flaps having an upper tab and a lower tab and a diagonal fold-line extending across the flap, said fold-line being in positioned to permit said flap to be moved to position the top edge of said upper tab to be received in the slit in the adjacent of said end walls, said top tab being slid through the adjacent end wall, said bottom tab being received within the adjacent of said slots in said bottom wall and said end flaps being in face-to-face relationship with the adjacent of said end walls.
Claim 6
Dependent Claim
200 words
A tray comprising a bottom wall, an end wall connected to each end of said bottom wall by a fold-line and extending substantially perpendicular to said bottom wall, a slit in each of said end wall at least one slot in said bottom wall adjacent to each of said fold-lines, a pair of side walls foldably connected one to each side of said bottom wall and extending substantially perpendicular to said bottom and end wall, end flaps foldably connected one to each end of each said side wall and extending substantially perpendicular to said side walls said end flaps being positioned between said end wall, each of said end flaps having an upper tab and a lower tab and a diagonal fold-line extending across the flap, said fold-line being in positioned to permit said flap to be moved to position the top edge of said upper tab to be received in the slit in the adjacent of said end walls, said top tab being slid through the adjacent end wall, said bottom tab being received within the adjacent of said slots in said bottom wall and said end flaps being in face-to-face relationship with the adjacent of said end walls.
Claim 7

33 words
A tray as defined in claim 4 wherein said end walls and side walls are substantially the same height and wherein said top tabs do not project above said end of side walls.
Claim 8
Dependent Claim
37 words
A tray as defined in claim 4 wherein the distance between each said slit and said bottom wall is substantially equal to the distance between the bottom of each of said upper tabs and said bottom wall.
Claim 9
Dependent Claim
87 words
A tray as defined in claim 6 further comprising a top foldably connected to the top edge of said side walls, said top comprising a top panel, a tuck flap foldably connected to said top panel at the side thereof remote from the connection of said top to said selected side wall and further tuck flaps one at each side of said top panel folded substantially perpendicular to said top panel in a position to be slid through the adjacent said slot in said adjacent end wall.
