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 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.

The present invention disclosed a fold-flat carrying box that's easy to store and transport. When it comes time to use a carrying box, it can easily be folded up, along with the pre-made fold lines, into a box-shape container and ready for customers' need. The materials for the carrying box can be made from paper of suitable stock, or plastic or other flexible materials, greatly increasing the ease of use and lowering the cost of storage and transportation.

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 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 carton is formed by folding and interconnecting a plurality of body pieces to establish at least front and rear panels and opposing side panels which can be joined to establish the carton with an interior cavity for containing edible products. At least two of the front, rear and opposing side panels are interconnected by one or more bridge tabs 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.
