Box designs, blanks for forming boxes by folding, collapsible and non-collapsible boxes formed thereby, and manufacturing methods therefor are disclosed. An exemplary box is formed from folding a single sheet of material having fold lines therein. The assembled box includes a lid comprising a top panel having top side panels that extend partially within the interior of the box and partially on the exterior of the box when the box is assembled and the lid is closed. Overlapping side panels of the box define openings through which the top side panels extend in crossing over from the exterior of the box to the interior of the box. In a feature, the openings defined in the sides of the box are covered by the top side panels when extending there through. In another feature, the box is collapsible when in the assembled state.

A container includes a first end structure defining a first opening therein, the first end structure being configured to receive a first cover positioned on the first end structure and extending across the first opening. A second end structure is positioned opposite the first end structure and defines a second opening extending through the second end structure. The container further includes two opposing side walls coupled to the second end structure along a respective first set of fold lines and two opposing end walls coupled to the second end structure along a respective second set of fold lines. At least one of the two opposing end walls extends obliquely relative to the second end structure and taper outwards from the second end structure. The container further includes a second cover positioned on the second end structure and extending across the second opening.

Assembling method of flattening-realizable file rack, comprising following steps: gluing; grey board pasting; folding; opening-burying; and forming. File rack assembled from the flattening-realizable file rack assembly method, comprises first single-powder cardboard body, wherein second single-powder cardboard body is formed at left side of the first single-powder cardboard body, third single-powder cardboard body is formed at right side of the first single-powder cardboard body, fifth single-powder cardboard body is vertically formed at top end of the first single-powder cardboard body, fourth single-powder cardboard body is formed at left side of the fifth single-powder cardboard body, and bottom end of the fourth single-powder cardboard body is connected with top end of the second single-powder cardboard body, sixth single-powder cardboard body is formed at right side of the fifth single-powder cardboard body, and bottom of the sixth single-powder cardboard body is connected with top end of the third single-powder cardboard body for forming.

An easy to assemble and store, recyclable assembly of a produce basket with a complementary carrying sleeve, assembled from pre-formed flat components that fold into shape is disclosed.

A container including a bottom portion and a plurality of peripheral wall portions extending from the bottom portion and defining an interior area of the container. At least one peripheral wall portion has an inner surface including a feature defining an inner ledge extending into the interior area, the inner ledge being located between the bottom portion and an upper edge of the container. The at least one peripheral wall portion has an outer surface including a feature defining an outer ledge located between the bottom portion and the upper edge of the container. The inner ledge is positioned to engage the outer ledge of a similarly-configured container whereby a spacing between a stack of nested containers is defined by the outer ledge of the similarly-configured container seated on the inner ledge of the container.

A method of forming a container from a blank of sheet material using a machine is provided. The blank includes a bottom panel, two side panels, two end panels, and a reinforcing panel assembly extending from a first side panel. The machine includes a hopper station, a corner post forming station, and a plunger station. The method includes rotating the reinforcing panel assembly upwardly toward the first side panel as the blank is transported from the hopper station to the corner post forming station, forming a corner wall and a reinforcing end tab by folding reinforcing panels about fold lines as the blank is transported through the corner post forming station, rotating the side panels and the end panels to be substantially perpendicular to the bottom panel by directing the blank through the plunger station, and coupling the reinforcing end tab to an end panel to form the container.

This document describes an assembly structure for corrugated packaging. The assembly structure is made from a single flat piece of fiberboard, including a center panel, two partial side panels, and two tabbed side panels. The center panel forms the bottom (or top) of the packaging. Tabbed side panels form two sides of the packaging, and the partial side panels, combined with the tabs or the tabbed side panels form the other two sides. The assembly structure can be made from corrugated fiberboard. The flutes of the corrugated fiberboard run in a direction that causes, when the panels are folded, the flutes of the two tabbed side panels to be vertical, providing strength in the stacking direction. While the flutes in the partial panels are horizontal, when the tabs of the tabbed side panels are folded to mate with the partial side panels, the flutes of the tabs are also vertical.
