A method and apparatus are shown for securing a top for a cardboard carton where the carton has a bottom wall and integral sidewalls, an initially open interior and initially open top flaps with outwardly extending ears. The top flaps are folded to a carton closing position which closes off the initially open interior of the cardboard carton. The ears are also folded to a position in contact with the sidewalls of the carton. A set of punches are aligned with the folded ears of the carton and are actuated to force a first layer of cardboard from a respective top flap through an underlying region of the carton sidewall. A set of platens are located so as to underlie and reinforce the sidewalls of the carton as the punching operation takes place.

Plastic corrugated reusable boxes are provided. Two opposite side panels 12 erected from a blank over fold lines 18 at bottom panel edges; said side panel 12 having flaps 20 attached on either side folded inward and interlocked with flaps 22 folded inward from the opposite side. Narrow flaps 32 attached to top edges of said side panels 12 folded inward and flat. The rest two opposite side panels 14 erected over fold lines at rest bottom panel edges; top flaps 30 attached to the rest two side panels 14 folded inward covering the top surface. Interlocked flaps 20 and 22 are standing underneath top flaps 30 and alongside two opposite side panels 14. Lock tabs 40 attached to top flaps 20 folded down and inserted into said lock slots embedded in narrow flaps 22 alongside side panels 12 top edges.

A leak resistant bliss-type container comprising a first blank defining a bottom wall, opposed first side walls hingedly connected to longitudinal edges of the bottom wall and extending upwardly from the bottom wall, a vertical side flange hingedly connected to each of a pair of opposing lateral edges of the first side walls, and opposing bottom flanges hingedly connected to lateral edges of the bottom wall and extending upwardly in overlapping relation to the vertical side flanges. Second and third identical end blanks are provided, each end blank defining at least an end wall secured in overlapping relation to the vertical side flanges. A corner piece is defined by a web of material, each corner piece extending between a longitudinal edge of one of the vertical side flanges and a longitudinal edge of the bottom flange to define a leak resistant corner.

Containers for column or cross stacking and related methods. In some embodiments, the top wall of the container may comprise a first plurality of vent openings and the bottom wall may comprise a second plurality of vent openings. One or more of the first plurality of vent openings is configured to be aligned with one or more of a plurality of vent openings formed in a bottom wall of an adjacent container positioned above the container in a column-stacked configuration, and one or more of the first plurality of vent openings is configured to be aligned with one or more of the plurality of vent openings of the adjacent container in a cross-stacked configuration. Various stacking tabs/openings may also be provided, which may be configured to facilitate either cross or column stacking, as desired.

The following summary concerns the development of a folded leak-proof container (46) that consists of one piece of fiberboard or cardboard (1) containing slits and folds that produce the center panel (3), the top panel (4), the bottom panel (5), the side panels (6 and 7), and the end panels (8-15), the latter of which contain lengthwise slits (18-25) to be folded in order to form the side handles of the container (46); the container may also include a top handle (2). The main function of the container (46) is to keep cool, transport, and cool items that must be refrigerated; it can do so through the addition of ice or any coolant compatible with the material used to manufacture the container.

The present disclosure is directed to a box for use in packaging, storing and displaying items. The box has a one-dimensional configuration before it is formed and a three-dimensional configuration after it is formed. The three-dimensional configuration is formed from a blank which lies flat and with a plurality of fold lines. The three dimensional configuration of the box includes a base portion, four side portions, two lid portions and a platform within the interior of the box that is capable of moving in a vertical manner.
