Abstract: A waterproof, anti-wicking, and fully recyclable corrugated container comprises a base portion having a bottom wall, a pair of opposite side walls, a pair of opposite end walls, and a plurality of joined flaps foldably joined with the side walls and the end walls. Each of the plurality of the joined flap folds onto itself to form a gusset that is attached to the respective side walls. A lid portion is telescopically engaged over the base portion such that is coextensive in length and width with the base portion side walls and end walls. The lid portion comprises a score or crease line formed along near free edge of the side walls to inhibit liquid from traveling up through the side walls.

Abstract: A packaging carton for wet food such as meat and fish is made of a triple ply lamination, the top and bottom plies being plastic sheet, the intermediate ply being of carton material such as paperboard but in variants the ply is made of fluted board, honeycomb matrix or side by side thin walled tubes. The intermediate ply is cruciform allowing the corners to be rectangular areas of plastic plies joined together. These form, diagonal fold flaps which are adhered to the cruciform blank to form a fold flat carton precursor. A lid is constructed in the same manner and overlies the carton to form a container which withstands tape wrapping.

Abstract: A tray composed of a unitary, continuous blank has an inner surface and an outer surface. The tray comprises a bottom wall, a plurality of sidewalls extending upwardly from the bottom wall and a plurality of minor flaps. Each of the plurality of minor flaps is connected to one of the sidewalls via a fold line and has a respective outer edge. At least one of the minor flaps is connected to a sidewall via a first cut score. The first cut score extends upwardly from the bottom wall without extending to an outer edge of the minor flap. The at least one minor flap is separated from the sidewall via a knife cut. The knife cut extends from near the outer edge of the minor flap downward toward and near the first cut score. The at least one minor flap has a second cut score formed therein. The second cut score extends from near the separation means. The first and second cut scores are formed from opposing surfaces of the blank so as to form a partial web.

Abstract: A corner join in a box is formed from a blank having a base section (2) and two side wall panels (4, 6) each joined thereto via a fold line (3, 5). A joining flap (15) is joined to one of the side wall panels (6) via a fold line (7). The fold line of the joining flap (15) essentially defines the corner, and the point of intersection of the three fold lines (3, 5, 7) is located in the base panel approximately at the corner. The side wall panels are joined to one another by placing the joining flap in contact with the second side wall panel (4) such that it overlaps the later in an overlap area, and fixing it to the side wall panel. A mastic-like filler (204; FA) is applied in or on the inside of the panel fold line (3) to which the fixing flap (15) is fixed at the location of the overlap area with the fixing flap (15).

Abstract: The present invention relates to a paper pack for containing milk or beverages, etc. sanitary and for keeping the refrigerator cleanly preventing the smell. More particularly, it relates to a sanitary pack, which provides a method for opening and closing a paper pack without occurring any inconvenience, by sealing up the room of paper gap tightly as itself without any supplementary attachments or devices such as clip, pin, etc. this sanitary pack offer prevention of over flowing of the contents of beverage by falling over during its use after its opening and convenience of keeping the contents of beverage clean with easiness by folding the cutting section of the paper pack in the refrigerator as well. It is highly effective promoting the degree of airtight of paper pack itself.

Abstract: A carton blank having an outer layer of a relatively rigid material, a first inner layer of a relatively rigid material superposed over a portion of the outer layer and a second inner layer of a relatively flexible layer of a fluid impervious material is provided with first and second weakened portions so that, after a carton has been formed from the carton blank, filled with a desired material and sealed, the first weakened portion may be broken to form a flip top lid which when moved in an arcuate path will gradually sever the second weakened portion to form an opening in the carton so that an amount of the desired material may be removed from the carton. The carton also may include a feature which allows the flip top lid to be securely re-closed after initial opening of the lid.
