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is covered by the cover, the protrudable portion may be protruded over the top panel to prevent the tongue from being withdrawn from the opening.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 container for heating a food product. The container comprises a base layer of material and a liner releasably attached to an inner surface of the base layer. The liner is separable from the base layer after heating the container. The container comprises a bottom panel, and end panel foldably connected to the bottom panel, a side panel foldably connected to the bottom panel, and a corner panel foldably connected to the bottom panel. The corner panel extends between the end panel and the side panel.

A packaging container having a top side, a bottom side extending parallel to the top side, and at least one side wall extending between the top side and the bottom side. The top side can have at least one protrusion, and the opposite side extending parallel can have at least one recess, into which a protrusion of a packaging container, for example, an identically shaped packing container, can be inserted. Such a packaging container can be produced in an economical and environmentally friendly manner, for example, by having holes punched in the top side and in the bottom side, and the protrusions and recesses attached in inserts, which are inserted into the packaging container.

A registration system including an insert including a center segment and a rail, the rail extending upwards from the center segment; and a register defining a cutout, the rail sized to fit within the cutout of the register, the cutout receiving the rail, the register configured to slidably move along the rail while maintaining a position parallel to the center segment.

A liquid retaining folded laminar container made from a cold or heat pre-cut paper or plastic sheet. The laminar container comprises engraved lines that enable folding to form a container. The laminar container has a circular base having a double concentric cone. The laminar container's sides close on itself to create a self-bearing square, or geometric, outline container with lids. The container is manually formed from the an engraved laminar sheet. The containers can be stored and transported flat.

An enclosable and stackable container comprising a tray and lid is provided with structural elements to permit rapid covering and uncovering of the tray, efficient stacking of containers, and safe transportation. At least one catching mechanism may be engaged quickly to securely cover the tray and its food contents and disengaged quickly to uncover the tray and its food contents, improving food hygiene practices. Foldable flange flaps enhance stacking strength to permit safe transportation of stacked containers and their food contents.

The present invention is a scalable, lockable container designed to prevent children from accessing the contents in the container. It includes an inner tray that is slidably mounted within an outer sleeve in releasable locking engagement. The lock mechanism includes a lock tab carried at one end of the inner tray that engages an engagement edge formed inside the outer sleeve. When so engaged, the inner tray is locked within the outer sleeve and cannot be removed from the outer sleeve. The lock tab is released by applying pressure to the outer sleeve, adjacent the lock tab, to disengage the lock tab from the engagement edge in the outer sleeve. This allows the lock tab to move past the outer sleeve engagement edge so the inner tray can be withdrawn from the outer sleeve, providing access to the contents of the box.

A container includes a base panel. An opposed pair of end panels extends from the base panel at opposite ends of the base panel. A front panel extends from the base panel and extends from a first one of the end panels to a second one of the end panels. A back panel extends from the base panel and extends from the first one of the end panels to the second one of the end panels. The end panels taper so top edges of the front and back panels are either longer or shorter than bottom edges of the front and back panels. Each end panel includes a plurality of overlapping end flaps adhered to one another. The end flaps of each of the end panels are connected to a respective one of the base panel and each of the front and back panel at respective fold lines.
