Abstract: A collapsible tray is formed from a single blank of cut and scored foldable material and comprises a generally rectangular bottom panel, side walls extending from opposite sides of the bottom panel and end walls extending from opposite ends of the bottom panel. Corner connecting flaps are provided at each end of the side walls and abbreviated top panels are foldably attached to the upper edges of the side walls. The top panels also include corner reinforcing flaps located at each respective end. The corner connecting flaps are adhered to the inner surfaces of the end walls at each corner and the corner reinforcing flaps are folded downward inside the tray to overlap the corner connecting flaps. The corner reinforcing flaps are retained in place when tabs included on the ends thereof are inserted in slots provided in the bottom panel and with the aid of additional locking tabs provided on the corner connecting flaps which are accessed by openings provided in the end walls.

Abstract: A self locking container is provided of the telescoping tray and cover type wherein the components are normally collapsed for storage but which may be squared for filling, closing and shipment. The locking elements comprise an outfolded locking flange on the tray component and a combination glue flap/locking flap arrangement infolded on the cover component. The container may also include a convenient removable tab element for releasing the locked components for opening the container and corner tab elements for retaining the normally collapsed side walls of the tray component in an upright condition for filling and closing.

Abstract: A multi-product merchandising package comprises a base pad having a plurality of products situated thereon covered by a heat shrunk film overwrap. The base pad is prepared from a combination of at least one sheet of single wall corrugated paperboard bonded to at least one sheet of single face corrugated paperboard in such a manner that the corrugated surface of the single face sheet faces upwardly. The corrugated surface of the single face sheet is selectively embossed in a pattern that corresponds to the size and shape of the products situated thereon for positioning and retaining the products on the base pad. The heat shrunk film conforms to the shape of the products and base pad to form a compact unit package. Where desired, base pads may be positioned at both the top and bottom of the packaged products.

Abstract: A reinforced end sealed container is prepared from a singe blank of paperboard that is symmetrically cut and scored to provide a bottom panel, foldably attached side and end wall panels, a pair of top closure flaps and a plurality of corner connecting panels, the improvement wherein the top closure flaps are also provided with integral end seal flaps and the end walls are provided with T-tabs, which, together with a notched portion of at least one of said top closure flaps, produces a container with superior end sealing strength. The notched portion of at least one of the top closure flaps serves as a reinforcing compression column between the T-tabs to provide increased resistance to any damage the container or its contents might suffer when the container is sealed closed.

Abstract: A side loading produce container is disclosed which is folded into its final configuration from a single flat blank of corrugated paperboard or the like. The folding sequence produces a container having three-ply end walls, two-ply sided walls and an integral top and bottom. The container includes integral top-to-bottom corner posts at one side thereof and a combination tab and slot manufacturer's joint alignment feature.

Abstract: The invention relates to a self locking container comprising an integral tray and cover. Both the tray and cover are assembled without adhesive by tab and slot combinations provided in the walls thereof. In addition, the tab and slot combination for securing and locking the cover portion also serves as an automatic locking device for locking the cover to the tray when the container is closed.

Abstract: A panel locking means is provided for securing together two or more corrugated paperboard panels in face-to-face contact. For this purpose, the panels to be secured together are provided with notches which have a narrow entry portion along the edge of a panel and taper outwardly to a wider base portion interiorly of the panel, and locking tabs which have a relatively narrow hinge portion interiorly of a panel and taper outwardly to a wider end portion along the edge of the panel.

Abstract: A reusable container for shipping returnable bottles of soda or beer is prepared from a single flat blank of material such as corrugated paperboard without stitching, gluing or stapling. The folding sequence is arranged such that the container comprises double thick side walls, end walls prepared from five thicknesses of material, a triple thick bottom and a captured wire rim reinforcing member in the upper end. The resulting container has increased strength and durability as compared with prior art containers of the same type.

Abstract: An improved heavy duty, octagonally shaped bulk container is disclosed which is preferably used with a pallet. The container comprises a tubular body portion with a plurality of outer side walls having upper and lower flaps foldably attached to the ends thereof. The end flaps are selectively folded inwardly and locked into either a rectangular or octagonally shaped end closure. The end closures are prepared from flat sheets that are cut and scored for either the rectangular end or octagonal end closure configurations. The container further includes an inner liner member that is cut and scored to correspond to the octagonal shape of the container and a pair of upper and lower end reinforcing panels.

Abstract: A container for use in a trash compactor is formed from a one piece substantially rectangular blank of paperboard that is cut and scored to provide leakproof, overlapping panel corner bellows folds and dimensions whereby the depth from top-to-bottom and length of the container from side-to-side are substantially equal while the width of the container from front-to-back is less than the other two dimensions.
