Abstract: An erectable container apparatus constructed from a substantially square blank of material for use in releasably storing various articles therewithin. The apparatus includes a plurality of side panels each having an inner edge attached to a base portion, an outer edge attached to a corresponding top flap member, and a left and right edge. The left and right edges are operably positioned at acute angles relative to the respective inner edges to which they intersect so as to provide substantially upright and inwardly sloping side panels upon articulation of the erectable container apparatus toward and into its fully articulated orientation. Locking elements are operably associated with at least two of the top flap members for releasably locking the erectable container apparatus in a fully erected orientation, as well as to releasably maintain the top flap members and the inwardly sloping side panels in a base and article covering orientation.

Abstract: A box formed of corrugated cardboard which is assembled in a reinforced manner so as to transport heavy objects such as books. An improved gripping hole is provided from an end wall extension twice folded over, resulting in a broader bearing surface. Disclosed are lid panels with a curved portion and a straight portion which interlock and prevent deformation. The bottom of the box is substantially reinforced by side wall extensions which are inserted through cutouts in end wall extensions and laid back to form substantially the entire inner bottom surface of the box.

Abstract: A container for produce is formed from a flat unitary blank of corrugated paperboard. The container sides include length and width panels and four corner panels. The container bottom is preferably formed by four interlocking panels, each of which is foldably attached to the bottom edge of a respective length or width panel. To facilitate erection of the container from its shipping, flattened configuration, a generally triangular gusset is provided at the lower end of each corner panels, foldably secured to the latter along one of its three sides. A second side of each gusset panel is foldably secured to respective minor bottom panels secured to the width side panels. The third side of each gusset panel is a free side or edge, not being connected to any panel. Each gusset panel is folded over on itself and located between adjacent bottom panels. Upon folding of the minor panels towards each other, the gussets cause the container to assume an octagonal configuration.

Abstract: A carton having a tubular body with a pair of opposed sidewalls and a pair of opposed endwalls, with end panels and side panels for a closure extending therefrom. At least one end panel is hinged to an endwall and has a free edge defining a pair of spaced notches with a retention flap therebetween, thereby forming a pair of locking tabs, one at each free corner of the end panel. At least one hinged tab is struck out from each side panel. The hinged tab includes a tab hinge line and a double-ended severing line extending to spaced apart portions of the tab hinge line so as to form a tab which is swingable out of the plane of the side panel, thereby exposing a locking edge of the side panel formed by the severing line. The locking tabs of the end panel deflect the hinge tabs into the interior of the carton to form recesses in the side panels into which the locking tabs are inserted so that the locking edge of the tab engages the locking edge of the side panel.

Abstract: A carton includes a tubular body with a pair of opposed sidewalls and a pair of opposed endwalls. A closure extending from the sidewalls and endwalls includes end panels and side panels joined to the endwalls and sidewalls with hinge lines. The end panels have a discontinuous free edge which extends across a pair of free corners. A recessed edge is located between the free corners and defines a pair of U-shaped locking edge portions on either side of a generally arcuate intermediate portion. A pair of locking recesses are formed in each side panel, each recess including an arcuate edge portion spanning a generally truncated V-shaped edge portion. The recessed edge of the end panels engages the locking recesses of the side panels to lock the carton closure.

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.

Abstract: A corrugated fiberboard shipping container for fresh produce the container having a tubular body, a bottom closure which is formed by four bottom flaps, and a re-openable and re-closable top closure at the top of the container. The top closure is formed by four top flaps, each top flap being folded inwardly with respect to the body panel to which it is attached to extend transversely therefrom. Each of an opposed pair of top flaps has a pair of spaced apart elongate slots therein which extend, respectively from the juncture of each such top flap with its body panel partly to the free edge thereof. Each of the other opposed pair of top flaps has a pair of spaced apart cuts therein extending from the free edge partly to the juncture of such top flap with its body panel. The cuts form a spaced apart pair of locking tabs in the free edge of each of the other opposed pair of top flaps with an intermediate tab therebetween.

Abstract: A container having a body formed from a plurality of side panels foldably joined to each other to form a tubular structure with bottom closure flaps foldably joined to the lower edges of certain of the side panels and arranged in overlapping interlocked relation, and wherein certain of the bottom closure, flaps have slots therein for receiving lower portions of certain of the side panels to help the container maintain its original shape.

Abstract: A shipping container and blank therefor are provided wherein the container is particularly suitable for accommodating a wide variety of produce. The container includes a pair of opposed upright side panels and a pair of opposed upright end panels, said pairs being interconnected by first foldlines. Major closure flaps are connected by second foldlines to the side panels and extend therefrom towards one another in a closing mode. Minor closure flaps are connected by third foldlines to the end panels and extend therefrom towards one another in a closing mode and at least partially overlap exterior surfaces of the major closure flaps. Each major closure flap is provided with a pair of relatively spaced locking slots.

Abstract: A paperboard carton having a self-locking bottom for holding heavy produce and the like which may be made with minimum waste and cutout material. The minor or width flaps have an inwardly folding flap locking segment which, then folded, defines a generally rectangular opening centrally located along the outer edge of the minor flaps. The major or width flaps have a flap locking slit formed therein. An assembly flap hingedly formed in the major flap may be folded inwardly to create an assembly slot along a portion of the flap locking slit.

Abstract: A wire dispensing and storage box is provided with a plurality of flap tabs appending to the top and bottom portions of the box which are inserted within a plurality of flap slots within the side portions of the box, respectively, so that the top and bottom portions of the box will not interfere with the paying off of the wire from the coil. The flap slot/flap tab construction helps prevent the cones, which provide integrity to the box and help support the wire therein, and locking tabs, which lock the box, of the top of the box and the cones and locking tabs of the bottom of the box from contacting each other in the center of the box thereby facilitating the dispensing of the wire.

Abstract: This relates to an end structure for a carton, and more particularly to a carton for packaging a light bulb having a projecting base. The end structure is formed of two pairs of end panels, the first pair of end panels including two opposite disposed generally rectangular end panels having slot-like openings therein disposed in angular relation with respect to the connection between the respective end panel and a side wall of the carton. The other pair of end panels are also oppositely disposed and having sloping side edges disposed at a complimentary angle relative to the angle of the openings with respect to the fold line connecting it to the respective side wall. Each of the second end panels has a projecting tab which is lockable within the respective one of the openings.

Abstract: A paper box for collecting used sanitary cotton or the like. The box is composed of water proof thick paper and defined by two pairs of opposing vertical walls and a bottom composed of flaps continuously extending from the four vertical walls. A pair of retention flaps continuously extend from a first pair of opposing vertical walls at top edges thereof. Each retention flap is foldable inwardly and has a free end substantially parallel to said opposing two parallel vertical walls in the first pair. The free end is indented to form a first cutout. Form one of the opposing vertical walls in a second pair continuously extends a ramp flap. The ramp flap is foldable inwardly and has a pair of latch lugs. Each latch lug is arranged to fall into the cutout as the ramp flap is inwardly folded over the pair of retention flaps.

Abstract: A carton for produce and the like has a bottom closure provided by pairs of major flaps and minor flaps hingedly connected to the carton body side walls and end walls, respectively. The major flaps have L-shaped slots cutout adjacent each end of the major flap, each slot providing a pair of generally perpendicular slot legs with one leg terminating adjacent the hinge line connecting the major flap to a side wall of the carton body and the other leg extending longitudinally of the major flap to provide a locking edge generally parallel to such hinge line with the edge terminating at an end abutment. Each minor flap has a fold line segregating an end portion of the minor flap and a cutout segment disposed centrally along the outer end of such end portion, this segment defining spaced locking corners at its opposite ends with projecting tabs on the end portion disposed laterally of the segment ends.

Abstract: An octagonal container closure in which the bottom closure flaps are held in place while the structural integrity of the flaps is maintained. Locking apertures are placed in opposed side closure flaps. The apertures remove as little material as possible from the side closure flaps and maintain the rectangular shape of the flaps. The apertures are shaped and located to allow the corners of the opposed end closure flaps to protrude through the apertures and to lock behind the side closure flaps. The shape of the apertures provides a two-way lock on each corner of an end closure flap, holding it both in the length and width direction. This provides a firmer closure than has been previously achieved.
