A self-erecting packing case formed from a single board blank, the packing case comprising: first and second side walls and first and second end walls integrally connected together along respective parallel fold lines; a first-type base panel integrally connected to a bottom end of each of the first and second side walls along a respective fold line; and, a second-type base panel integrally connected to a bottom end of each of the first and second end walls along a respective fold line; wherein each first-type base panel is glued to an adjacent second-type base panel and comprises a fold line along an edge of where the first-type base panel is glued to the adjacent second-type base panel; and wherein each first-type base panel further comprises a lobed section integrally connected along a fold line, wherein the lobed sections of each first-type base panel are arranged to deflect and then interlock with each other when the packing case is erected from a collapsed condition, thereby to form the base of the packing case.

A container that is configured to have an open state and a closed state, in which the container includes an outer cell having a plurality of side panels including a first side panel and a second side panel. The outer cell defines a chamber having a first opening. An inner locking member is attached to an inner wall of the first side panel. An extension panel is coupled to the second side panel. The extension panel includes a first cover panel and a tuck flap, in which the tuck flap includes an extension member and a tuck flap locking member. In the closed state of the container, the first cover panel covers the first opening, and the extension member and the tuck flap locking member are tucked inside the chamber. A bias member biases the tuck flap locking member toward a first position to cause the tuck flap locking member to engage the inner locking member.

An example blank for a break pack container is described. The blank includes first and second fold lines extending across at least a portion of a sheet of cardboard material. The blank includes wall portions bounded by the first and second fold lines, one of the wall portions including a first perforated section or cutout formed between the first and second fold lines. The blank includes a first top flap extending from the first fold line, the first top flap including first and second opposing ends, the first end of the first top flap including a first side flap connected to the first top flap by a third fold line. The first side flap is configured to be folded over a wall portion and inserted into the first perforated section or cutout when the sheet of cardboard material is folded into the assembled configuration.

A collapsible box includes a plurality of side panels including a first side panel and a second side panel, each of the plurality of side panels defining a side panel top edge; a box bottom; and a box top comprising a plurality of top panels including a first top panel extending from the side panel top edge of the first side panel and a second top panel extending from the side panel top edge of the second side panel, the second top panel comprising an overlapping portion; wherein, in a folded-down configuration of the collapsible box: the first side panel confronts the second side panel; and the overlapping portion of the second top panel is folded over a top panel top edge of the first top panel.

A carton for holding containers can be converted from a first configuration for storing and shipping the containers therein to a second configuration in which the carton forms an open-top cooler for chilling and serving the containers. A beverage container cooling carton is dimensioned for increased ice surface contact with the outer surfaces of a number of the beverage containers such that heat transfer between the ice and beverage containers occurs efficiently.

A method of collapsing a collapsible box includes providing the collapsible box, the collapsible box comprising: a plurality of side panels including a first side panel and a second side panel, each of the plurality of side panels defining a side panel top edge; a box bottom; and a box top comprising a plurality of top panels including a first top panel extending from the side panel top edge of the first side panel and a second top panel extending from the side panel top edge of the second side panel, the second top panel comprising an overlapping portion; folding the first side panel towards the second side panel to confront the first side panel with the second side panel; and folding the overlapping portion of the second top panel over a top panel top edge of the first top panel.
