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 paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal to establish fluid communication between an interior of the container and the environment outside the container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

Methods and systems for integrating multiple portions of a container are provided. The method and system are specifically designed for integrating multiple shell portions with ear lobe-shaped tabs. The method comprises: providing a first set of retention structures to be associated with a plurality of inter-connecting features formed on an edge of a first shell part, wherein the first set of retention structures comprise at least a lead-in feature and a retention feature; providing a second set of retention structures to be associated with a plurality of inter-connecting features formed on an edge of a second shell part, wherein the second set of retention structures comprise at least a deflection feature and a retention feature; and engaging the two shell parts with aid of the retention structures.

A carton. The carton may include a floor panel; a plurality of side panels extending about a periphery of the floor panel, a front tab formed at an upper edge of a front side panel, upper side flaps extending from upper edges of a first end side panel and a second end side panel, and wherein each flap includes a side receiving slot; foldable corner gussets extending between adjacent side panels, wherein the floor panel, side panels, and foldable corner gussets are configurable to form a compartment region; a hingeable lid, including: a lid panel, a front edge flap, a side tab formed on each opposing side edge of the lid panel, and a front receiving slot formed in the front edge flap, wherein the lid panel is configured to cover the compartment region when in a closed position; and wherein the front tab of the front side panel is configured such that when the hingeable lid is in the closed position, the front tab aligns with the front receiving slot and is receivable therein and each side tab aligns with its respective side receiving slot and are receivable therein.
