The side walls of the tray which have the openings have, in each case in the region above the wall portion which has the at least one opening, a freely upwardly projecting tongue (9), which is connected via a bending line (10) to the wall portion which has the at least one opening, and is located beneath the tongue. In the fitted state of the lid, the tongues of the side walls butt against sloping portions (59) of the lid.

A carton with a removable lid, the carton may include a floor panel; a plurality of side panels extending about a periphery of the bottom panel. The one or more of the side panels may include one or more tabs extending from an upper edge thereof. The carton may further include foldable corner gussets extending between adjacent side panels. The bottom panel, side panels, and foldable corner gussets may be configurable to form a compartment region; and a removable lid. The removable lid may include a lid panel and one or more slots formed in the lid panel, wherein the lid panel may be configured to cover the compartment region, and wherein the one or more slots may be sized, shaped, and positioned such that when the removable lid is installed atop the compartment region, the one or more tabs align with the one or more slots and are received therethrough.

A container for supporting a food product includes a tray and a liner. The tray includes a plurality of panels at least extending at least partially around an interior of the tray, the plurality of panels comprising a bottom panel, at least one side panel, at least one end panel, and at least one corner panel. The liner includes a central panel and at least one marginal panel each foldably connected to a gusset. The container is reconfigurable between a first configuration in which the at least one end panel and the at least one corner panel are in generally planar overlying relation with the respective bottom panel and the at least one side panel, with the liner positioned therebetween and with the gusset in a folded arrangement, and a second configuration in which the at least one side panel, the at least one end panel, and the at least one corner panel are generally upright relative to the bottom panel with the gusset in an expanded arrangement.

Blanks for forming clamshell containers and the resulting clamshell containers are described. The clamshell containers include a tray and a lid that are hingedly connected together. The tray is liquid tight, and typically includes gussets on each corner to prevent leakage. The lid and tray can be locked via at least one locking mechanism, optionally two different locking mechanisms. A first locking mechanism involves a front panel on the tray, with an extension portion that terminates in a hook or tab. The extension portion can fold over the front panel of the lid, and the hook or tabs slide into a slit(s) on the top of the lid. An optional second locking mechanism involves lid detents and tray detents. In some embodiments, in the locked position, the lid detents are underneath the tray detents and the tray detents retain the lid detents in place until a force is applied.

A packaging container includes a first portion and a second portion that are placed on each other. Each of the first portion and the second portion has a projection polygonal surface having a projection polygonal shape, side portion polygonal surfaces extending from respective sides of the projection polygonal surface, a plurality of to-be-folded surfaces provided between the respective adjacent side portion polygonal surfaces, and a peripheral portion extending over an entirety of an outer edge. The first portion and the second portion are connected to each other at the peripheral portions by a side seal portion obtained by sealing the peripheral portions to each other, or by a connection portion obtained by folding the sheet material, and have air-tightness except for an opening.

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.

Provided is a folding packaging cooler box convertible from a box mode to an unfolding mode or vice versa, comprising: a box portion having a bottom portion, sidewall portions and joint portions configured to connect with one another and to form a single plane in the unfolding mode; and a cooling reinforcing portion configured to be inserted to the inside of the box and to form a hexahedron shape together with said box portion when said box portion is converted into the box mode, wherein said cooling reinforcing portion comprises a reinforcing bottom portion configured to form a lower surface and to face the bottom portion of the said box portion upon conversion into the box mode; reinforcing sidewall portions configured to connect with the said reinforcing bottom portion and to face the sidewall portions of said box portion; and reinforcing joint portions configured to join said reinforcing sidewall portions, to be folded to face itself and to be in close contact with the reinforcing sidewall portions, upon conversion into the box mode, and wherein said reinforcing bottom portion, said reinforcing sidewall portions and reinforcing joint portions form a single plane in the unfolding mode.

A blank of foldable sheet material is provided. The blank includes a bottom panel, a first bottom side panel and a second opposing bottom side panel extending from opposing side edges of the bottom panel, and a front panel extending from a front edge of the bottom panel. The front panel includes opposing side edges. The blank also includes a first and a second diagonal panel extending from a front edge of the first and second bottom side panels, respectively, and a third and a fourth diagonal panel extending from each side edge of the front panel. The third and fourth diagonal panels have a length greater than a length of the first and second diagonal panels. The blank includes a first and a second corner panel, wherein the first corner panel is hingedly connected to the first and third diagonal panels and the second corner panel is hingedly connected to the second and fourth diagonal panels.

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.
