ABSTRACT:
A container having a tray portion and a cover sealed to the peripheral top edges of the tray. Cut score lines on the inner side of the cover provide a splitting of the paperboard of the cover upon opening to allow the cover to be peeled from the tray to a hinge at the back edge of the tray. Offset double cut score lines may be provided on the upper and lower sides of the cover at the front edge of the tray, which will split upon opening of the cover to yield overlapping locking flaps which can be used to reclose the cover. Flanges may be attached to the lateral side edges of a paperboard tray by cut score hinges, and adhered to the inner side of the cover to provide layer separation of the flanges upon opening rather than layer separation of the cover. Alternatively, double cut score lines can be formed along the lateral sides of the cover in position to register with lateral side flanges on the tray, which split and provide overlapping locking flaps when the cover is opened. The cover can then be completely removed from the tray upon opening, and is reclosed by inserting the locking flaps on the removed portion of the cover under the locking flaps projecting from the tray.
