A packaging container may include a top part with a pouring spout for pouring the contents of the container. The packaging container may further include a tubular body part with an upper end and a lower end, the upper end being joined together with the top part along a circumferential edge of the upper end of the body part. The body part may further include a first group of crease lines extending from a lower end of the body part towards its upper end. The top part may include a recessed portion, the recessed portion and the first group visually forming one surface. A surface near the interface area between the first group of crease lines and the recessed portion of the top part may provide gripping support for one or more fingers of a hand when the packaging container is held by the hand and the remaining fingers while pouring the contents from the packaging container.

The invention relates to a method and an apparatus (22) for closing the top side of external cardboard packagings (1). The external cardboard packagings (1) comprise two top closing flaps (3, 4) located opposite each other. Side edges (42) of the closing flaps (3, 4) are connected to each other via two fold-in flaps (5, 6). During closing, at least two external cardboard packagings (1) are positioned in a group (50) contiguous to each other or slightly spaced apart. At least two folding devices (23) are advanceable toward each other to engage the fold-in flaps (5, 6) of each of the at least two external cardboard packagings (1), thus pressing the fold-in flaps (5, 6) toward each other and folding them over their particular second fold edges (60) and third fold edges (7), thereby folding down the top closing flaps (3, 4).

Provided is a hybrid-construct bag, comprising a bag body formed by at least a first sheet, the bag body having: a substantially tubular main body portion, a first end portion, a second end portion, a valve section formed at the first end portion and configured to form the channel between the top and bottom walls which are included in the valve section, and a patch section, wherein the main body portion, first end portion and second end portion cooperatively form a cavity operable to receive contents. There are a plurality of perforations formed in the main body portion and used for allowing a gas to pass though and resisting a liquid and/or particulates to pass though. A method of forming the hybrid-construct bag is also disclosed.

A carton for holding at least one article includes a plurality of panels that extends at least partially around an interior of the carton. The plurality of panels includes a front panel, a first side panel, a second side panel, and a back panel. A plurality of end flaps includes a first end flap foldably connected to the front panel and a second end flap foldably connected to the back panel. A first gusset is foldably connected to a portion of the first side panel and a second gusset is foldably connected to a portion of the second side panel. At least the first end flap, the first gusset, and the second gusset cooperate to form a first closure of the carton, and the second end flap forms a second closure of the carton. The second closure at least partially overlaps the first closure.

A top forming part creasing mechanism for forming a top portion of a paper container, the top forming part creasing mechanism includes: a first creasing device (4) that valley-folds, along horizontal folding lines (111, 113), a right side panel (112) and a left side panel (114) of a carton blank (126) fitted onto a mandrel so as to spread out the right side panel and the left side panel from a center to an outer side of the carton blank; a second creasing device (5) that makes creases by inwardly mountain-folding a top upper surface panel (108) and a top upper surface auxiliary panel (110) along horizontal folding lines (107, 109); and a third creasing device (6) that makes a crease by outwardly valley-folding a sealing panel (117), which is provided on an edge of the top upper surface auxiliary panel, along a horizontal folding line (116).

Provided is a hybrid-construct bag, comprising a bag body formed by at least a first sheet, the bag body having: a substantially tubular main body portion, a first end portion, a second end portion, a valve section formed at the first end portion and configured to form the channel between the top and bottom walls which are included in the valve section, and a patch section, wherein the main body portion, first end portion and second end portion cooperatively form a cavity operable to receive contents. There are a plurality of perforations formed in the main body portion and used for allowing a gas to pass though and resisting a liquid and/or particulates to pass though. A method of forming the hybrid-construct bag is also disclosed.

A carton for holding at least one article includes a plurality of panels that extends at least partially around an interior of the carton. The plurality of panels includes a front panel, a first side panel, a second side panel, and a back panel. A plurality of end flaps includes a first end flap foldably connected to the front panel and a second end flap foldably connected to the back panel. A first gusset is foldably connected to a portion of the first side panel and a second gusset is foldably connected to a portion of the second side panel. At least the first end flap, the first gusset, and the second gusset cooperate to form a first closure of the carton, and the second end flap forms a second closure of the carton.
