Abstract
A carrying tray is provided incorporating a top member of single face corrugated paper board which is bonded to a bottom member made of a single paper board. The bottom member extends beyond the top member and forms a substantially triangular beam bounding the perimeter of the top member to provide a rim for improving the stability and strength of the tray. A tab extending from one of the beams is adhesively bonded to an adjacent beam to provide strength at a corner of the tray. The tray can be economically and readily decorated using commercial printing systems such as flexographic gravure and silk screening.

A tray, comprising in combination:
- a top member having a first and a second side with said first side comprising a top surface of the tray;
- a bottom member having a first and a second side with said second side comprising a bottom surface of the tray;
- means mounting said second side of said top member to said first side of said bottom member with one of said top and bottom members extending beyond the other of said top and bottom members forming a first and a second rim portion;
- each of said rim portions having a first fold line;
- means for mounting said rim portions to said other of said top and bottom members establishing obtuse folds at said first fold lines and establishing acute folds located beyond said other of said top and bottom members forming a rim for the tray;
- and means connecting said first rim portion to said second rim portion to secure said rim portions relative to one another.

- said second rim portion having a notch fold line;
- said second rim portion having a tab adjacent said notch fold line;
- means for mounting said first side of said rim portions to said first side of said top member establishing obtuse folds at said first and third fold lines and acute folds at said second fold lines with said bottom corner edges engaging one another forming a first and a second beam about said first and second edges of said top member, respectively;
- and means for mounting said tab to said first beam to secure the first beam relative to said second beam to provide a rim for the tray.

A substantially rigid tray, comprising in combination;
- a top member having a first and a second edge forming a corner at the intersection thereof,
- said top member including a top sheet having a first and a second side and an intermediate member having a first and a second side;
- said intermediate member having corrugated peaks on said first and second sides;
- adhesive means for mounting said corrugated peaks of said first side of said intermediate member to said second side of said top sheet with said intermediate member extending to said first and second edges of said top member;
- a bottom member having a first and a second side;
- adhesive means for mounting said first surface of said bottom member to said corrugated peaks of said second side of said intermediate member with said bottom member extending beyond said first and second edges of said top member forming a first and a second rim portion, respectively;
- each of said rim portions having a first, second and a third fold line sequentially spaced and substantially parallel to said first and second edges of said first member, respectively;
