ABSTRACT:
A package including a flanged tray and a wrapper surrounding it. The tray typically contains a foodstuff such as a pie. The wrapper is formed of a rectangular, unitary blank of paperboard which is folded and wrapped aroung the tray, the wrapper being folded to the form of a tube with the tray therein. The wrapper includes two oppositely located latching flaps (24) whose free edges (28) are curved so as to match the curvature of the tray. The curved or arcuate latching flaps are initially folded downwardly more than 90 degrees from the plane of the blank. Other portions (16, 18) of the blank are bent upwardly along respective transverse fold lines (23), causing the arcuate latching flaps to bow inwardly and beneath the flanges of a tray (32) and contact the tray flanges (34). Portions (16, 18) of the wrapper are then folded beneath and on the sides of the tray and ends (17) are overlapped and glued together to finish the package. If the tray is rectangular instead of round or oval, the free edges (28) of the flaps (24) are straight.
