A paperboard carton is formed by interconnecting a main body piece, folded to establish at least a bottom wall and first and second spaced side panels, with separately formed third and fourth side panels. To strengthen the carton and enable similarly configured cartons to be effectively, vertically stacked, a caliper or basis weight of each of the third and fourth side panels is made greater than the main body piece and/or an orientation of the fibers between the pieces is varied as compared to a conventional carton.

A reinforced box for containing a plurality of items to be packaged includes a bottom wall and a top wall, a pair of first side walls and a pair of second side walls. The bottom wall, the top wall and the pair of first side walls are formed from a one-piece elongate element, which extends along a longitudinal axis and is formed with transverse fold lines. The pair of second side walls consists of two separate cardboard panels, and each of the walls is formed with longitudinal creasing lines defining pairs of first and second folded side wings. The pair of second side walls is glued to the bottom wall using a respective second side wing overlapping the bottom wall to reinforce its longitudinal edges. A method of making a box with a reinforced structure is also disclosed.

A blank assembly for forming a container includes a body blank that includes a bottom panel and two opposing side panels. The side panels are configured to at least partially form two opposing side walls of the container. The blank assembly also includes at least two end blanks. Each end blank is configured to form at least a portion of an end wall of the container. Each end blank includes a first inner corner panel, a first inner end panel, a first reinforcement panel, a second reinforcement panel, and a second inner end panel coupled together in series along preformed, parallel fold lines. The first inner corner panel is configured to extend obliquely between a side wall and an end wall. The first reinforcement panel is configured to extend from the first inner end panel inwardly towards an interior cavity of the container.

A carton (5) is formed by folding and interconnecting a plurality of body pieces (15, 19, 21) to establish at least front and rear panels (25,35) and opposing side panels (59,77) which can be joined to establish the carton with an interior cavity (90) for containing edible products. At least two of the front, rear and opposing side panels are interconnected by one or more bridge tabs (56-58; 100; 110, 115; 120, 121; 130, 131; 150-152; 160-162) so as to constitute a unitary, single one of the separate body pieces, thereby preventing the interconnected panels from skewing during assembly of the carton.

A foldable box having a first, substantially flat and unfolded configuration which can be easily and conveniently transformed into a second, three-dimensional configuration capable of retaining one or more items.

A container for storage of molten material from an industrial facility, and method of manufacture thereof, is provided to maximize internal volume of the container while providing structural stability. The container includes walls having rounded convex-shaped edges at each wall junction. A first head is connected to the walls at a first end of the container, and a second head closes the second end of the container. The second head is connected to the walls at a second end of the container. Corners are defined at the intersection of the walls with the first head and second head at the first end and the second end respectively. A first flange is connected to the first head to receive molten material, and the first head is shaped as a tapered shoulder to smoothly transition from the first flange to the junction of the walls.

A blank assembly for forming a container includes a body blank that includes a bottom panel and two opposing side panels. The side panels are configured to at least partially form two opposing side walls of the container. The blank assembly also includes at least two end blanks. Each end blank is configured to form at least a portion of an end wall of the container. Each end blank includes a first inner corner panel, a first inner end panel, a first reinforcement panel, a second reinforcement panel, and a second inner end panel coupled together in series along preformed, parallel fold lines. The first inner corner panel is configured to extend obliquely between a side wall and an end wall. The first reinforcement panel is configured to extend from the first inner end panel inwardly towards an interior cavity of the container.

A shipping container convertible to a display tray is provided and may comprise: a floor panel; first and second end panels; a first positioning panel defining a first notch with the first end panel; a side panel extending between the first and second end panels; and a first containment panel comprising a first main portion and a first end portion extending at an angle to the first main portion. The first end portion may be located in the first notch such that the first end panel and the first positioning panel frictionally engage the containment panel first end portion to frictionally hold the first containment panel in position. The first containment panel may be removable so as to convert the shipping container to a display tray.

A box (200) is disclosed. The box is manufactured from a first part (2), a second part (4) and a third part (6) of a sheet material, which parts have been subjected to gluing to each other with adhesive (8) so as to form a box shape; wherein said first part (2) of said sheet material represents a bottom portion (10), a first side portion (12) and a second side portion (14) of said box, respectively, as a coherent entity; wherein said second part (4) and said third part (6) represent opposite end portions (16,18) of said box; wherein said first part (2) is having an extension in a first direction X and in a second direction Y; said first direction X is being perpendicular to said second direction Y; wherein said first part (2) comprises a first side edge (20), a second side edge (22), a first end edge (24) and a second end edge (26); wherein said first part (2) along said first side edge (20) thereof comprises a first inner side edge recess (28) being cut into the material of said first part; and a first outer side edge recess (30) being cut into the material of said first part; wherein said first part (2) along said second side edge (24) thereof comprises a second inner side edge recess (36) being cut into the material of said first part; and a second outer side edge recess (34) being cut into the material of said first part; wherein said first part (2) along said first end edge (22) thereof comprises a first inner end edge recess (32) being cut into the material of said first part and a first outer end edge recess 38 being cut into the material of said first part; wherein said first part (2) along said second end edge (26) thereof comprises a second inner end edge recess (40) being cut into the material of said first part and a second outer end edge recess (42) being cut into the material of said first part; wherein a first fold line (44) and a second fold line (46), each being parallel to said first direction (X), are being defined between said first inner side edge recess (28) and said second inner side edge recess (32); thereby defining a bottom portion (10) being arranged between said two side portions (12,14) of said first part; wherein in respect of each of the two side edges (20,22) and in respect of each of the two end edges (24,26), the material of said first part, along the inner and the outer recesses (28,30); (32,34); (36,38); and (

A foldable file box includes: a plastic sheet including a bottom wall and two side walls that are foldable relative to the bottom wall to form a U-shaped structure; two side frames interlocking with the bottom wall and the two side walls to form a box structure including a top opening; two hanging rods each including a bottom portion interlocking with the top part of the plastic sheet, and two ends of each hanging rod respectively interlocking with the two side frames; and a top cover interlocking with the two side frames and the two hanging rods to close the top opening.
