A packaging element for accommodating at least one product includes a blank which has a number of portions connected to one another by folding lines. The portions include an accommodating portion having at least one receptacle, the shape of which is matched to the shape of a product to be accommodated, a first side-wall portion, a first cover-wall portion, a second side-wall portion, and a second cover-wall portion. The first cover-wall portion may have at least one hollow, and the second cover-wall portion may have at least one protrusion with a shape and position complementary to the hollow.

A tray for holding one or more food products includes a plurality of panels including a central panel, a plurality of compartment flaps foldably connected to a respective panel of the plurality of panels, and a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the plurality of compartment flaps and the plurality of end flaps are overlapped to form a plurality of compartments of the tray.

A carton for holding one or more articles includes a plurality of panels extending at least partially around an interior of the carton, the plurality of panels including a front panel, a back panel, and at least one side panel. The carton also includes a plurality of end flaps foldably connected to respective panels of the plurality of panels and forming a closed top portion of the carton, the closed top portion of the carton is reconfigurable between a first configuration having a substantially flat profile and a second configuration forming a handle of the carton. The carton also includes locking features for engaging at least one other carton.

An apparatus and method utilizes a forming machine which includes a mandrel and forming plate each shaped to conform the paperboard and/or corrugated material blank passing through the mandrel into the desired configuration for a leak-proof tray. The blank includes a layer of a suitable paperboard and/or corrugated material, and a layer of leak-proof plastic or paper material disposed over one side of the corrugated material. The corrugated material includes cutouts at each corner of the blank that enable the sides and ends of the blank to be folded relative to one another. The paper material continuously overlaps the surface of the corrugated layer and these cutouts to provide a continuous leak-proof barrier layer within the formed tray and at the corners of the blank when folded to form the tray, as the paper material is folded over itself to form a bellows corner in the tray.

An interlocking three dimensional display system is described that includes a plurality of interlocking units. The interlocking units are easily coupled together and may be coupled in multiple varied orientations utilizing various combinations of an upper and base unit. The interlocking units are easily collapsed and fold flat for transportation.

A tearable leak-resistant container is provided with creases, partial perforation along selected creases, adhesion of flaps, and a collapsed position to permit rapid reconfiguration to an expanded position. The expanded position of the container enables enhanced filling with food ingredients and transportation without spillage. The adhered flaps provide enhanced leak resistance, and the perforated creases permit disassembly of the container to improve access to the food contained within.

A carton defines a bottom wall, a first side wall coupled to the bottom wall, a second side wall disposed opposite the first side wall and coupled to the bottom wall, a first end wall coupled to both the bottom wall and first and second side walls, and a second end wall disposed opposite the first end wall and coupled to both the bottom wall and the first and second side walls. The carton is formed from a blank having a first side and a second side disposed opposite said first side. The first side defines the interior surface of the bottom wall and the interior and exterior surfaces of the first and second side walls and the first and second end walls.

A carton for holding at least one article includes a plurality of panels extending at least partially around an interior of the carton, the plurality of panels includes a top panel, a bottom panel, a front panel, a back panel, and at least one side panel, and a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the plurality of end flaps includes at least one top end flap foldably connected to the top panel. The at least one top end flap is upwardly folded relative to the top panel to at least partially maintain a closed configuration of the carton in which the top panel is recessed below a portion of each of the front panel, the back panel, and the at least one side panel to form a recessed top portion for receiving a portion of a vertically adjacent carton.

A foldable container moveable between a flat configuration and a three-dimensional configuration is provided. The container includes a first panel having a first engagement feature, a second panel having a second engagement feature, and a third panel having a third engagement feature. The first engagement feature is configured to engage with the second engagement feature so as to secure the container in the three-dimensional configuration. The first engagement feature is also configured to engage with the third engagement feature so as to inhibit the first engagement feature from becoming disengaged from the second engagement feature.
