A tray for holding at least one food product includes a plurality of panels extending at least partially around an interior of the tray, the plurality of panels including a bottom panel, a front panel, a back panel, and at least one side panel, a plurality of end flaps foldably connected to a respective panel of the plurality of panels and cooperating to form a rim extending outwardly from the plurality of panels, and locking features comprising at least one male locking feature extending from at least one end flap of the plurality of end flaps, the at least one male locking feature at least partially inserted through at least one female locking feature in a respective panel of the plurality of panels to reinforce the rim.

A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.

A method of forming a tray for holding at least one food product includes obtaining a blank having a plurality of panels including a bottom panel, a front panel, a back panel, and at least one side panel, a plurality of end flaps foldably connected to a respective panel of the plurality of panels, and reinforcement features. The method further includes folding the plurality of panels at least partially around an interior of the tray, folding the plurality of top end flaps to form a rim extending from the plurality of panels when the tray is formed from the blank, and activating the reinforcement features to maintaining an integrity of the rim such that at least one end flap of the plurality of end flaps is biased downward to maintain an outward arrangement from a respective panel of the plurality of panels.

A tray for holding at least one food product includes a plurality of panels extending at least partially around an interior of the tray, the plurality of panels including a bottom panel, a front panel, a back panel, and at least one side panel, and a plurality of end flaps including a plurality of top end flaps cooperating to form a rim extending from the plurality of panels, each top end flap of the plurality of top end flaps foldably connected to an adjacent top end flap of the plurality of top end flaps.

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.

A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels, each corner panel having an edge connected to a respective one of the first and second side panels and having an edge connected to the inner end panel. First and second locking tabs are defined in the outer end panel, each locking tab being defined by a lateral separation line located longitudinally inward from an outer longitudinal edge of the outer end panel and extending laterally to define a free tab end.

Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.
