A tamper resistant latching mechanism is provided with an insert tab and wings on a first section used in conjunction with a slot and release panel on an opposite hingedly connected section.

A food receptacle having a tray with a base, a perimeter wall extending therefrom, and a tongue extending from the perimeter wall along a longitudinal axis and a cover adapted to cover the tray. Cover has an opening adapted to receive the tongue therethrough, such that the tongue is inserted through the opening when the tray is covered by the cover. Tongue may include a protrudable portion adapted to protrude away from the longitudinal axis. When protruded, the protrudable portion is adapted to abut the cover. When the tray is covered by the cover, the protrudable portion may be protruded over the top panel to prevent the tongue from being withdrawn from the opening.

A self-sealing container is formed from a blank comprising panels and end flaps connected along fold lines with the panels and the end flaps being foldable along the fold lines to form the container. The container includes a securing feature that seals the container in a closed position, with the securing feature providing a visual indication of opening if the container is opened from the closed position. After the container is opened, the securing feature provides a closure feature that allows the container to be closed.

A clamshell packaging for airtight packaging of foodstuff includes a tray folded out of a single sheet. The tray has at least two adjacent pool parts, each pool part having a bottom wall and upstanding walls arranged around the circumferential edge of the bottom wall. The adjacent pool parts are hingedly connected to each other along an upper edge of a respective upstanding wall, so the adjacent pool parts can be hinged on top of each other to form a closed box. A circumferential, horizontal flange is arranged to the tray to at least some upper edges of the upstanding walls. A plastic barrier foil is arranged in the pool parts and extends onto and substantially covers the flange. The flange includes a seal zone extending along the length of the flange. The seal zone is line symmetrical along the hinge line at the upper edge of the connected walls.

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.
