In accordance with at least one aspect of this disclosure, a twisted package can be configured to be flat in a collapsed state having one or more fold lines that are straight. At least a portion of the twisted package can be twisted in the formed state such that the one or more fold lines are bent in the formed state and/or such that a body of the twisted package is twisted in a formed state. Any suitable structure to form a twisted package is contemplated herein.

A method of erecting a carton from a blank, including: engaging the blank with a punch head against which the carton is formed, folding side portions of the blank against the punch head to form sides of the carton; folding outer portions of the side portions of the blank away from the punch head and against an external side of the carton; folding end portions of the blank against the punch head to form end portions of the carton; folding outer portions of the end portions of the blank away from the punch head and against an external end of the carton; and securing corner gussets formed between the side and end portions against sides or ends of the carton.

In a box assembly device, a holding mechanism causes one of bottom boards to contact a first jig and folds the bottom board inside, while the holding mechanism holding the box material in a state where the box material is developed in a cylindrical shape from a folded state. The folding mechanism folds the bottom flap inside so as to overlap with one of the bottom boards. The holding mechanism causes the other bottom board to contact the second jig while holding the box material and folds the other bottom board inside and upwardly so as to overlap with the bottom flap to engage the bottom boards with each other.

A blank for forming a box for serving pizza includes panels defined and separated by manufactured lines that, when folded, define a box having a first footprint for enclosing within the box an entire pizza and that, when folded differently with panels having been removed, define a second box having a second footprint for enclosing leftovers of the entire pizza, the second footprint being smaller than the first footprint. The second footprint preferably is approximately one half of the area of the first footprint for accommodating no more than half of the entire pizza.

Various blanks are provided for forming sleeves, containers, and other constructs for heating, browning, and/or crisping of a food item in a microwave oven, and for holding and/or transporting the food item after heating. The various blanks, sleeves, containers, and other constructs may include a removable portion defined by one or more lines of disruption that enable the removable portion to be separated from the remainder of the blank, sleeve, container, or other construct.

The present disclosure is directed to a box for use in packaging, storing and displaying items. The box has a one-dimensional configuration before it is formed and a three-dimensional configuration after it is formed. The three-dimensional configuration is formed from a blank which lies flat and has a plurality of fold lines. A second blank may be employed in forming the box. The three dimensional configuration of the box includes a base portion, four side portions, a cover portion and a platform within the interior of the box that is capable of moving in an angled manner out from the interior of the box upon opening the box and of moving inside the interior of the box upon closing the box.

A single piece container (200) made from cardboard, paperboard or other lightweight foldable sheet material is provided. The container (200) includes an outer shell and an inner shell. The outer shell has first and second ends (202, 204), and includes a plurality of outer shell sidewall panels (3, 5, 7, 9) hingedly connected to one other about respective outer shell sidewall foldlines. The outer shell sidewall panels (3, 5, 7, 9) extend between the first and second ends (202, 204) of the outer shell. At least the second end of the outer shell is a closed end. The inner shell includes a plurality of inner shell sidewall panels hingedly connected to one other about respective inner shell sidewall foldlines. The inner shell is integrally connected to the outer shell along a foldline. Each one of the inner shell sidewall panels is in face-to-face contact with the inner surface of a respective one of the outer shell sidewall panels (3, 5, 7, 9).

Disclosed is a packaging assembly that may include a blank for forming a corner lock. The blank for forming the corner lock may include a first body panel foldably connected to a side panel, a second body panel foldably connected to the side panel, where the first and second body panels may be foldable about the side panel to form a slot within the corner lock in an assembled position. The blank may further include a first and second locking panel foldably connected to the first body panel, and a third and fourth locking panel which may be foldably connected to the second body panel.

A packaging system includes a container defining an internal volume. The container includes a container body and a lid hingedly connected to the container body. The packaging system further includes a dunnage panel received in the internal volume of the container. The dunnage panel includes a plurality of discontinuous lines of weakness.

A blank for constructing a crush-tolerant container includes a first side panel, a bottom panel, a second side panel, and a top panel coupled together in series. At least one cutout and at least one bridge portion are defined along a first fold line between the top panel and the first side panel. The at least one bridge portion and the at least one cutout are configured to maintain the top panel in a plane spaced above a top edge of the first side panel when the container is formed and the top panel is not under a stacking load, and to allow the top panel to move downwardly such that at least a portion of the top panel is substantially co-planar with the top edge of the first side panel when the container is formed and the top panel is under the stacking load.
