Abstract: A container for packaging a product is provided. The container is formed from a continuous blank of sheet material having an internal surface and an opposing external surface. The container includes a top panel having a top edge, a bottom edge, and opposing side edges. The container further includes a hinge panel connected to the bottom edge of the top panel along a first fold line, a rear panel connected to the hinge panel along a second fold line and connected to the top panel, and a first adhesive coating applied on the internal surface of the rear panel adjacent to the opposing side edges and the bottom edge defining a perimeter of a compartment for receiving a product. Moreover, after the product is placed in the compartment, the top panel and the rear panel are folded about the hinge panel such that at least a portion of the internal surfaces of the top and rear panels are attached to one another. A method of constructing the same is also provided.

Abstract: A shipping system for packing and transporting products, such as case ready food items, in which the products require a certain amount of separation between layers. The shipping system comprises a shipping unit, formed by at least one substantially open-topped tray, preferably two or more, that are stacked atop one another, with a cover placed atop the uppermost tray, and held together by banding or strapping. Preferably, the tray(s) and cover are fabricated from corrugated paperboard material.

Abstract: A passive interlock structure for use in containers (such as cartons and trays), particularly those fabricated from corrugated paperboard and the like, which permits the facilitated aligning of vertically stacked containers. The passive interlock structure feature includes recesses formed in the tops or bottoms of the containers, and corresponding complementary low planar projections in the bottoms or tops of the containers.

Abstract: A carton is provided with an automatic bottom panel, which extends from a side panel, and has two converging reverse-scored fold lines, which extend outwardly from the side panel. One end flap featuring an angled score is folded up from the automatic bottom panel and is glued to its body panel. Adhesive is applied only above the diagonal folding score, leaving the unglued section free to fold in reverse in the bottom formation. The other end panel bottom flap is folded inwardly in the box joining process and a second of that flap with another diagonal score is folded in reverse for glue application. As the main panels are folded in the final gluing process the reverse folded glued section adheres to the outside surface of the previously mentioned major bottom flap. As the carton is brought into square during the erection process, the flaps self-form into a solid, full-overlapping bottom.

Abstract: An improvement is provided for a pizza-style paperboard container. The improvement includes first and second separation lines extending through first and second lateral panels, respectively. An additional fold line is provided in the first lateral panel at a location rearward of the first separation line, the material therebetween defining a closure flap. The first lateral panel includes opposed side panels. These side panels include a pre-formed hinge. The second lateral panel also includes opposed side panels. As assembled, the side panels of the first lateral panel are exterior to the side panels of the second lateral panel. After the carton is first assembled in a conventional manner, it may be reduced in size by breaking the carton in two along the separation lines. The closure flap is then pushed inward while the hinges of the outer side panels capture the inner side panels.

Abstract: A lock flap closure arrangement for one-piece, collapsible, tray-type, paperboard container which container includes a tray and a cover hinged to the tray. The closure arrangement includes a tray cover with at least one lock flap having a T-shaped lock tab hinged thereto with a major port ion adapted to be inserted into a complementary receiving opening in an adjacent area of the tray.

Abstract: A tray-cover, corner closure arrangement for a hexagonal, one-piece, collapsible, tray-type, paperboard container with diagonal front corners. The container includes a tray, with front end and tray side wall panels interconnected by a four section gusset, and a cover hinged to the tray and including a pair of corner lock tabs adapted to be inserted between the tray corner gussets and the tray bottom wall panel.

Abstract: A one-piece, collapsible, tray type, paperboard container with one or more truncated corners, each of which includes a pair of vertical side walls, with adjacent ends spaced from each other and interconnected by a three-piece gusset. The gusset includes first and second sections, foldably joined to each of the side walls, and a corner section, foldably joined to each side section. The corner section is folded in face-to-face relation with one of the side sections and positioned against an inner surface of one of side walls in interlocking engagement therewith.

Abstract: A container formed from a unitary blank of foldable paperboard that has an internal divider panel, with an integral handle at one end thereof, and that has an end wall formed by pairs of overlapping end closure flaps that are recessed to form a common opening affording access to the internal handle.

Abstract: A collapsible box that can be formed from a one-piece sheet of foldable paperboard and that has opposed side and end walls and a top wall or cover that includes a pair of sections hinged to the end walls and that can be kept closed by snug, interlocking, frictional engagement between inner and outer panels of the side walls.

Abstract: An outer container, formed from a unitary blank of foldable paperboard, for use with an inner flexible bag in a composite package adapted to hold and dispense liquids. The container includes a detachable tab in the bottom wall, to provide access to a bag spout, and an integral, internal, wedge-shaped ramp, formed entirely from material of the bottom wall and adjacent side walls of the container, and which is located adjacent a lower rear corner of the container to help evacuate liquid from a bag positioned within the container.

Abstract: A blank for forming a paperboard box has portions for forming side walls and end walls of a container and major and minor flaps which interlock to form a bottom to the container. The flaps are connected to the side and end walls along hinge lines. The major flaps include slits or slots which receive tabs on the minor flaps to maintain the bottom closed. The slit or slot of the major flap extends from the center thereof to the hinge line separating the major flap from the side wall. The hinge line between the major flat and the side wall includes pair of spaced parallel fold lines which diagonally extend from the hinge line and intersect the slit or slot. These spaced diagonal fold lines which are offset in alignment, cause the slit or slot to open when the major closure flat is folded over, thereby facilitating insertion of the tab into the slot or slit.
