Abstract: Blanks for forming two-compartment containers and the resulting containers are described herein. The container includes a tray and four closure flaps hingedly connected thereto. The closure flaps can be closed to enclose food or other substances therein, or opened to provide access to and removal of the tray contents. The tray is separated into two compartments by an interior partition. Generally, each compartment is liquid tight. Each compartment includes a bottom, three sidewalls, one partition wall, and four corners; each corner is adjacent to a folded gusset. Two opposing sidewalls are located on a first set of opposing sides of the bottom and a third sidewall and the partition wall are located on a second set of opposing dies of the bottom. Each folded gusset generally adheres to an adjacent sidewall. In at least one compartment, each opposing sidewall contains an extension portion that adheres to its adjacent opposing sidewall.

Abstract: Blanks for forming clamshell containers and the resulting clamshell containers are described. The clamshell containers include a tray and a lid that are hingedly connected together. The tray is liquid tight, and typically includes gussets on each corner to prevent leakage. The lid and tray can be locked via at least one locking mechanism, optionally two different locking mechanisms. A first locking mechanism involves a front panel on the tray, with an extension portion that terminates in a hook or tab. The extension portion can fold over the front panel of the lid, and the hook or tabs slide into a slit(s) on the top of the lid. An optional second locking mechanism involves lid detents and tray detents. In some embodiments, in the locked position, the lid detents are underneath the tray detents and the tray detents retain the lid detents in place until a force is applied.
