A collapsible, reusable shipping box has an initial flat configuration, a box configuration and a mailer configuration. In the mailer configuration, the mailer can be returned.

Provided herein is a machine for forming a container from a blank including a tray and a lid. The machine has an upstream end where the blank is loaded and a downstream end where the container is discharged and includes a frame, a pre-forming assembly, and a mandrel assembly. The pre-forming assembly is configured to partially form the lid and the tray by folding each of a plurality of side panels of the blank and further form the tray by partially folding a front panel assembly of the blank, the front panel assembly including a front panel and a roll-over panel. The mandrel assembly is mounted to the frame and configured to engage a bottom panel of the tray to form each of a plurality of corners of the tray and fold the roll-over panel to form a front wall of the container.

A main die-cut element is divided along a predefined division line to obtain a first die-cut element and a distinct second die-cut element. Glue is deposited on a first portion of one from between the first die-cut element and a secondary die-cut element and on a second portion of one from between the second die-cut element and the secondary die-cut element. The method includes forming an opened die-cut element of the tray plus lid type given by the combination of the first die-cut element and the second die-cut element, wherein these two elements are coupled to the secondary die-cut element, with the first die-cut element and the secondary die-cut element partly superposed and pressed to one another at the first portion and the second die-cut element and the secondary die-cut element being partly superposed and pressed together at the second portion.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

A container formed from at least one blank of sheet material includes a tray, a cover configured to close the tray, and a locking device. The tray includes a tray front panel. The cover includes a cover front panel that extends downwardly from a front edge of a cover top panel. The cover front panel is configured to be positioned in an at-least partially overlapping arrangement with the tray front panel when the cover is closed. The locking device includes a locking tab hingedly attached to the cover top panel and struck in part from the cover top panel and in part from the cover front panel. The locking device also includes a locking recess struck from an upper edge of the tray front panel. The locking device is configured such that the locking tab can be pressed down into the locking recess to selectively secure the cover to the tray in a closed and locked configuration.

A device for automated packaging of articles, comprising a conveyor for feeding and transporting into the device a blank of corrugated cardboard, a pair of crease wheels for creating two longitudinal crease lines in the blank, a transversal blade or score applicator for successively creating four transversal crease lines in the blank as the blank is transported into the device, and opposite pressing members such as jaws of a press and/or pressing rollers, arranged symmetrically with respect to a center line of the device, whose lateral position is adjustable for their ends or tips to match the two longitudinal crease lines, and activated in a timely manner as the blank is transported into the device to crush the corrugated cardboard in the top, middle and bottom corners of the blank in order to make it easily foldable.

A locking device for a box includes a first panel defining a locking tab separable from the first panel and comprising a first tab subpanel and a second tab subpanel; the first tab subpanel extending from the first panel and the second tab subpanel extending from the first tab subpanel, the second tab subpanel including a neck and an ear, the ear extending from the neck in a lateral direction of the locking tab; and a second panel defining a locking opening, the locking opening sized to receive and capture the locking tab, the locking tab configured to engage an edge of the locking opening and thereby configured to prevent movement of the locking tab with respect to the locking opening in an opening direction of the locking device.

A fold flat tray having an erect configuration and a fold flat configuration. The erect configuration comprises, a base (1), and first (2) and second (4) side walls and flanges (8, 9) extending outwardly from the top edges of the side walls. The fold flat configuration comprises the two opposing first sidewalls (2) being folded inwardly about their respective fold lines (3) adjacent to the base such that they lay flat against the base. Each of the two opposing second side walls (4) is provided with a straight fold line (10) extending from each corner, across the second side wall and its associated flange (9) in an oblique manner, such that each second side wall has a central portion between two straight fold lines, and two peripheral portions on opposite sides of the straight fold flat lines with respect to the central portion.

A sealed container for the storage of a plurality of articles comprising an open topped receptacle having a lip that defines an opening through which the articles may pass into and from said receptacle and closure means, including a cover that is hingedly connected to the receptacle and which is sealably connected to the receptacle, for closing the opening. The receptacle also includes a flap that is hingedly connected to the cover and wherein the flap in one position is adapted to overly the cover and wherein information relating to the contents of the container is displayed on the cover and on the flap.

The invention relates to a clamshell packaging for airtight packaging of foodstuff, which packaging comprises: —a tray folded out of a single sheet of material, preferably cardboard, which tray has at least two adjacent pool parts, each pool part having a bottom wall and upstanding walls arranged around the circumferential edge of the bottom wall, wherein the at least two adjacent pool parts are hingedly connected to each other along an upper edge of a respective upstanding wall, such that the at least two adjacent pool parts can be hinged on top of each other to form a closed box, —a circumferential, horizontal flange arranged to the tray to at least some of the upper edges of the upstanding walls, and —a plastic barrier foil arranged in the pool parts and extending onto and substantially covering the circumferential, horizontal flange wherein the circumferential, horizontal flange comprises a seal zone extending along the full length of the flange, wherein the seal zone is line symmetrical along the hinge line at the upper edge of the connected walls.
