ABSTRACT:
A rectangular take-out carton which includes a flanged tray and tapered locking cover is disclosed. The tray flanges along the opposed sides are outwardly and downwardly extending and have an outward and upward bias which locks them behind and in edge-to-edge engagement with folded back and secured marginal portions of the associated side closure panels of the cover which are normally biased laterally inwardly. The end flanges of the tray are outwardly and downwardly extending for engagement with downwardly extending tapered end closure panels of the cover to provide a carrying flange and closure combination which creates a thermal seal and permits the weight of the carton and its contents to be supported thereby. The cover lock is released by pushing down and pivoting the cover side closure panels outwardly against their normal bias to free the folded back marginal portions from their edge-to-edge contact with the opposed outwardly and upwardly biased side wall flanges of the tray.
