Abstract

A nestable octagonal tray having tapered, glued side walls of low height. The tray has an octagonal bottom panel, four trapezoidal side walls each attached at its shorter parallel edge to the bottom panel, four trapezoidal side flaps each attached at its longer parallel edge to the bottom panel, and eight substantially rectangular glue flaps each attached along its base to one of the non-parallel sides of the trapezoidal side walls. The side flaps and glue flaps are adhered in overlapping relation.

Claims

1. An octagonal tray of less than one inch in height made from a one piece paperboard blank, said blank comprising:

a. an octagonal bottom panel having four sides defined by a first set of four score lines and four sides defined by a second set of four lines,

b. four trapezoidal side walls each having parallel top and bottom sides and a pair of nonparallel sides, said top sides being longer than said bottom sides, each of said trapezoidal side walls being attached at its bottom side to said bottom panel along one of said first set of score lines,

c. four trapezoidal side flaps each having parallel upper and base edges said base edges being longer than said upper edges, each of said trapezoidal side flaps being attached along its base edge to said bottom panel along one of said second set of score lines,

d. said trapezoidal side walls and side flaps being alternately disposed about the periphery of said bottom panel, and

e. eight generally rectangular glue flaps having a base, an inner edge, and an outer edge, one each of said glue flaps being attached along its base to one each of the nonparallel sides of said side walls along a common fold line.

2. The paperboard blank for forming a tapered octagonal tray as specified in claim 1 wherein the inner edge of each of said glue flaps forms an internal angle greater than 180°

with the score line forming the bottom side of the side wall to which the glue flap connects.

3. A tapered octagonal tray of less than one inch in height, comprising:

a. an octagonal bottom panel having four sides defined by a first set of four score lines and four sides defined by a second set of four score lines,

b. four trapezoidal side walls each having parallel top and bottom sides and a pair of nonparallel sides, saidtop sides being longer than said bottom sides, each of said trapezoidal side walls being attached at its bottom side to said bottom panel along one of said first set of score lines,

c. four trapezoidal side flaps each having parallel upper and base edges said base edges being longer that said upper edges, each of said trapezoidal side flaps being attached along its base edge to said bottom panel along one of said second set of score lines,

d. said trapezoidal side walls and side flaps being alternately disposed about the periphery of said bottom panel, and

e. eight generally rectangular glue flaps having a base, an inner edge, and an outer edge, one each of said glue flaps being attached along its base to one each of the nonparallel sides of said side walls along a common fold line, two of said glue flaps being overlapped with one of each said side flaps, and each of said common fold lines forming an angle greater than 90°

with one of the scored lines of the first set and

f. glue means for adhering said glue flaps to the side flaps which they overlap.

4. The tapered octagonal tray as specified in claim 3 wherein the inner edge of each of said glue flaps extends substantially along the score line forming the base edge of the side flap to which the glue flap is adhered to maximize the overlapping adhesive bonding area.

5. The tapered octagonal tray as specified in claim 3 wherein the outer edge of each of said glue flaps extends substantially along the upper edge of the side flap to which it is adhered.
