A container having both a one-dimensional configuration before it is formed into its three-dimensional configuration. A blank is used to form the container and is initially flat with a plurality of fold lines. The container includes a base portion with a plurality of edges along its perimeter, a lid portion which is distanced from and parallel to the base portion, and a wall projecting orthogonally from each edge forming a plurality of walls. At least one wall is integrally connected to both the base portion and the lid portion.

A blank for forming a carton includes a unitary substrate layer defining a primary axis and a secondary axis transverse to the primary axis. The substrate layer includes: a main panel having a side edge extending substantially parallel to the primary axis and an end edge substantially parallel to the secondary axis; an end outer panel connected to the end edge by a first fold line extending substantially parallel to the secondary axis; an end inner panel connected to the end outer panel by a second fold line extending substantially parallel to the secondary axis; a side outer panel connected to the side edge by a third fold line extending substantially parallel to the primary axis; a side inner panel connected to the side outer panel by a fourth fold line extending substantially parallel to the primary axis; a notch defined in a side edge of the end inner panel; and an integral tab extending from an end edge of the side inner panel adjacent the side edge of the end inner panel. The blank is configured to be erected into a carton by: folding the end outer panel relative to the main panel about the first fold line; folding the end inner panel relative to the end outer panel about the second fold line so that the end inner panel substantially faces the end outer panel and is deflectably spaced away from the end outer panel; folding the side outer panel relative to the main panel about the third fold line so that the side inner panel substantially faces the side outer panel, whereby a pocket is defined between the notch, the side outer panel, and the end outer panel; folding the side inner panel relative to the side outer panel about the fourth fold line so that the side inner panel substantially faces the side outer panel; and inserting the tab into the pocket to interlock the side inner panel and the end inner panel.

The present invention is directed to a container having increased compression strength. Embodiments of the container comprise a pair of opposing side walls, each of which may include at least one layer of corrugated board having horizontal fluting and at least one layer of corrugated board having vertical fluting. Embodiments of the container also comprise a pair of opposing end walls, each of which may include at least one layer of corrugated board having horizontal fluting and at least one layer of corrugated board having vertical fluting. Embodiments of the container may be prepared from a single blank of corrugated board and may have a bottom surface that is integral with each of the side walls and each of the end walls so as to be considered leak proof. Embodiments of the container may also be configured to be collapsible to a substantially flat arrangement.

An integrated carton and liner assembly for consumer products includes a paperboard tray and thermoformed plastic insert. The sidewalls of the assembled carton are four layers thick, interleaved, and secured with snap fitments for exceptional sturdiness. The assembly is easy to assemble without adhesive, and achieves an upscale look. The thermoform liner is held securely in the carton.

A folded-sheet container includes a bottom in a center portion of a sheet, side walls adjacent to the bottom, first and second folding lines from a periphery of the bottom toward a periphery of the sheet, a dart portion formed by folding back the sheet along the first folding line, a flap in an end portion opposing the bottom of the side wall and configured to be folded back, and an insertion piece in the flap. The dart portion is folded back along the second folding line to be overlaid on the side wall, the flap is folded back to sandwich the dart portion between the side wall and the flap, the insertion piece in the flap is folded back to be inserted into the dart portion, and the opposing two side walls as one pair are both curved to outwardly project in a radial direction in a plan view.

A storage container includes a bottom panel that has a parallel front edge and rear edge, and a parallel first and second side edge. A front panel is connected to the bottom panel along the front edge and is further connected with a front locking section. A first side panel is connected to the first side edge of the bottom panel and is further connected to a first side locking section. A second side panel is connected to the second side edge of the bottom panel and is further connected to a second side locking section. A rear panel is connected to the rear edge of the bottom panel and is further connected to a rear locking section. The rear panel has four deltoidal sections. The container is configured for rapid assembly.

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.
