A spout assembly with a spout and a cap. The spout has a cylindrical sidewall; a cylindrical base at the lower end of the sidewall and having a larger outer diameter than the sidewall; and a disk-like flange extending outward from the lower end of the base. The cap has a cylindrical peripheral wall with an internal thread and is screwed onto the upper end side of the spout sidewall. The spout sidewall also has a projection formed between the external thread and the recess so as to extend circumferentially and have a height lower than a height of the external thread, and with the cap screwed onto the spout, at least a portion of an upper surface of the base fits an inner side of a peripheral wall of the cap.

A packaging container formed by folding a sheet material and includes a container body that has a trunk, a top and a bottom. The trunk serves as side panels, while the top and the bottom are respectively connected to ends of the trunk. In the packaging container, a first weakened portion is linearly formed in the container body.

The invention relates to a container precursor comprising a wall, wherein the wall a) surrounds an interior region, and b) comprises a first wall region and a second wall region; wherein the first wall region comprises a first layer sequence comprising a first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the first wall region, a second carrier layer is characterised by a smaller layer thickness than a first carrier layer, or a third carrier layer, or both; wherein the second wall region comprises a second layer sequence comprising first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the second wall region, the second wall layer is connected to the third wall layer; wherein, in the second wall region, the third carrier layer is characterised by a larger layer thickness than the first carrier layer, or the third carrier layer, or both. Further, the invention relates to a process for manufacturing a container precursor, a container precursor obtainable through this process, a closed container, a process for manufacturing a closed container, a closed container obtainable through this process, a use of the aforementioned container precursor, and a further use of the aforementioned container precursor.

The invention is directed to a stackable container having a gable type top wall and a gable type bottom wall. The top wall of the container can include an upwardly extending tab that cooperates with a slot in the bottom wall of a like container to facilitate stacking of two or more containers. The container includes a front opening.

Provided is a package made of a composite material is represented and described, including a package base with two front base corners and with two rear base corners, a package gable with two front gable corners and with two rear gable corners, and a package base body with a front panel, a first side panel, a second side panel and a rear panel. The package base and the package gable are arranged on opposite sides of the package base body. The composite material has a polymer inner layer, a polymer outer layer and a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. In order to enable the manufacture of packages with even more complex geometries without impairing the rigidity of the package, it is proposed to provide a third sleeve fold line, which has a plurality of sections, which each adjoin a side panel and the rear panel, and of which at least one section is curved.

A paper inner container for storage of refilling liquid content, which enables a suction port to be easily formed at a center of an upper surface thereof. The paper inner container includes: four body panels, which form a body having a square tubular shape; and a pair of upper-surface forming panels and a pair of side panels, which are continuously provided on upper edges of the body panels to form an upper surface. The pair of upper-surface forming panels face each other and overlap in a vertical direction. The pair of side panels are positioned between the pair of upper-surface forming panels to face each other and are folded up along with overlapping of the upper-surface forming panels. The pair of upper-surface forming panels have holes, which are formed at centers of the upper-surface forming panels to serve as a suction port.

A carton blank for forming a carton, and comprising a row of first, second, third and fourth substantially four-edged panels, each panel having substantially the same width and comprising a side wall part, a top closure obturating part and a top sealing fin part, one of said panels from an outermost boundary of the side wall part to an outermost boundary of the top closure obturating part being substantially free from any lateral line of weakness, the obturating part of said one of said panels including a loop of weakness.

A sheet packaging material for producing a package comprises at least one first crease line and at least one second crease line, at least one third crease line which intersects said first crease line in at least one first point and said second crease line in at least one second point, at least one fourth crease line, at least one fifth crease line, which extends between said first point and said fourth crease line, at least one sixth crease line, which extends between said second point and said fourth crease line, said first point and said fourth crease line being spaced by a first distance, said second point and said fourth crease line being spaced by a second distance, said first crease line and said second crease line being spaced by a third distance, wherein the sum of said first distance and said second distance is less than said third distance.

A container with a non-heat-seal window and a process for fabricating a low surface energy container with a non-heat-seal window. The process comprises forming a container template and cutting an opening in the container template. A window comprising a window stock material, a releasable liner, and an adhesive positioned between the window stock material and the releasable liner is sized to overlap the opening. A portion of the adhesive is exposed and the window is positioned over the opening. The window is then secured to the container template over the opening without the need to apply heat, and the container template is folded into the low surface energy container with the window.
