A self-sealing container is formed from a blank comprising panels and end flaps connected along fold lines with the panels and the end flaps being foldable along the fold lines to form the container. The container includes a securing feature that seals the container in a closed position, with the securing feature providing a visual indication of opening if the container is opened from the closed position. After the container is opened, the securing feature provides a closure feature that allows the container to be closed.

Forming a cardboard blank includes making two score lines on a cardboard sheet to define a central sector with three portions and two lateral sectors. Four cuts are made in a direction transverse to the score lines to form in one lateral sector a first closing flap and first and second reinforcing flaps and, in the other lateral sector, a second closing flap and third and fourth reinforcing flaps. The first and second closing flaps are folded at respective score lines, and one portion folded to cover a flank of an article on another portion so the first and third reinforcing flaps project. A third portion is folded to cover another flank and an upper article face so the second and fourth reinforcing flaps project. A band folds the first two reinforcing flaps towards the first closing flap and the third and fourth reinforcing flaps towards the second closing flap.

Box blanks, bag-in-box systems, and methods for forming bag-in-box systems from box blanks. The box blanks (100) include portions and flaps configured to fold and interlock with each other so as to improve structural integrity and reduce lateral deformation, have cross-corrugation and simplified fabrication, and have fewer or no internal edges or corners that may jeopardize the integrity of a bag of liquid or pourable powder contained therein.

The invention is directed to a balanced process for extrusion of a plastic corrugated sheet or blanks, and subsequent converting of the blanks into plastic boxes. The process includes conveying the blanks to a plurality of forming stations for incrementally forming features on the blank needed for forming a box. The present process is performed at a slower speed than typical paper corrugated forming.

A paperboard food container includes a paperboard receptacle and a paperboard closure. The paperboard receptacle encloses, in an assembled state, a three-dimensional space in which a food product may be disposed and has an opening through which the food product enters the space. The paperboard closure is disposed across the opening, and includes first and second surfaces, one of the first and second surfaces, one of which has a tamper-evident region of weakness that may be irreversibly split to open the closure.
