A preferably one-piece fold-and-glue container has corners reinforced by extensions that fold over and compress self-erecting bellows or gusset corner joints, and cutouts in each of the four front, back and end walls. The corrugated paperboard panels of a single flat blank define a bottom, opposite front and back walls and longitudinally opposite end walls. The joints have bellows panels integral with the front, back and end walls, joined at folds oriented diagonally and being glued to one of the adjacent walls to pull one another perpendicular to the bottom when erected. The end walls have an outer end wall panel integrally extending from the bottom and joined adjacent to the front or back to an extension having a protruding tab at its free end for locking into the bottom when the extension is folded over the gusset joint. The cutout in each wall is spaced inwardly from opposite ends and extends only part way from a top edge to the bottom, leaving a lower wall portion adjacent to the bottom at which the material is doubled over and also locked to the bottom. Adjacent to the junction between the extension and the outer end wall, a registration tab is cut in the extension to register with a corresponding opening in the bottom of a container stacked on the container.

A container is made in a collapsed configuration with bellows fold corners for self erection. Outer end wall panels are joined to the container bottom, leading to horizontal ledge panels and inner end wall panels fold over and down to lock via tabs into openings in the bottom. Columns reside under the ledge panels and are provided by column forming panels folded inwardly and glued to the inner end wall panels. Fold lines define the corners of each column and bear against inner sides of the front and back walls holding the columns open. The column forming panels have protruding tabs back by corresponding tabs on one of the ledge panels betwen the inner and outer panels of the end walls. These tabs form a two thickness registration tab that engages a corresponding opening in the container bottom for stacking.

A container of paperboard, corrugated craft paper or the like is provided with one or more walls that moves inwardly with erection of the container and bears against an in-fold flap of an adjacent wall, to square up and reinforce the container. In one arrangement, two opposite hollow walls of a rectilinear container expand inwardly against two inner in-fold flaps, during folding of outer in-fold flaps associated with the two hollow walls, into a position in the plane of the container bottom. Embodiments are disclosed with variations including multiple plies, center dividers, integral lid panels and tear-outs. The container preferably is produced in a knocked down flat shape with four sidewalls folded flat on one another. The container is erected into a rectangular shape by pressing its diagonally opposite corners toward one another. The inner in-fold flaps first are folded up into the plane of the container bottom, which can be done with ample clearance because the adjacent hollow walls are at first flat and retracted. The outer in-fold flaps have a parallelogram connection with the inner and outer panels of the hollow walls, causing the inner one of the panels to move inwardly against the inner in-fold flaps, eliminating the clearance as the outer in-fold flaps are rotated into the plane of the container bottom.

A one-piece container having front, back and end walls is disclosed for use in storing, shipping and displaying the contents thereof. The front and back walls are reinforced in high stress areas, such as wall diagonals, by column members formed from panels that are integrally connected to the side and back walls. These column members thus remain tightly associated with the side and back walls and provide maximum strength and structural rigidity to the container. The column members are held in place by folding end wall panels that are integrally formed with the container bottom and which fold over the column members and lock into place with the bottom. The column members may be hollow geometric structures, or they may be flat sandwich structures formed from plural material layers. The container can be provided with registration tabs and corresponding openings to allow like containers to be stacked for storage or display.

A one-piece container having a top and bottom, front, back and end walls is configured for storing, shipping and displaying the container contents. A tear-out panel with multiple glued thicknesses spans a portion of adjacent walls, especially the front and adjacent top, and is removable to expose the contents. A reinforcing inside panel backs the tear-out area and also marginal areas around the tear-out panel in the front wall and top portion. The reinforcing panel can be a folded back extension from a top flap or laterally-inward extensions from column forming end wall structures. An outer ply of a portion of the tear-out panel may be removed prior to shipping, leaving the inside reinforcement panel to cover part of the opening, and simplifying tear-out. Containers incorporating this reinforced front and top panel display design can be either a unitary bottom construction, or a multi-piece folded bottom construction.

A folded and glued container has panels defining a back panel and laterally opposite first and second sidewalls and one or more shelf panels attached to the back panel and extending laterally between the two sidewalls. The container is constructed as a compact folded and glued container that can be readily erected by the end user and provides one or more shelf or partition like structures formed in part by panels that are affixed, in addition to an integral die cut panel, when processing the container in a fold and glue machine line.

A folded and glued container that quickly erects into a container having multiple shelf structures is formed of a plurality of panels defining a back panel, a front panel opposite the back panel, two longitudinally opposite endwall panels joined to the back panel and the front panel. The container further includes two laterally opposite sidewalls joined to the front panel. The back panel is integrally joined to one of the two endwall panels and attached to the other of the two endwall panels. Inwardly folded bellows panels extend between and integrally joined to the other of the two endwall panels and the sidewalls. When the sidewalls are folded upwardly from a knock-down-flat configuration of the container, the sidewalls erect the two endwall panels and the back panel into a rectilinear box in which multiple shelf panels cut out from the front panel are erected in unison into their final configuration.

A collapsible container for packing, shipping and displaying articles is formed from an integral piece of corrugated craft, paperboard or similar foldable material. The container includes a plurality of panels which are connected to form a bottom, front, back and exterior sidewalls, and preferably also a top. A bellows fold connects each of the exterior sidewalls with at least one of the front and back walls. Each exterior sidewall is provided with a respective interior sidewall which together support a horizontal ledge. The horizontal ledges are useful for stacking multiple cartons in vertical alignment and can support containers that are somewhat out of registry. Locking tabs extend from the bellows panels of the container to limit lateral deflection of the sides and deformation of the container.
