A bag includes a body with a closed and stepped end, and an opening in the closed end as a handle. A tube having a first panel, a second panel and two side gussets is provided. The tube is foldable inward along a longitudinal fold line on each of the two side gussets. A stepped end is formed. The first panel has a first longitudinal length, the two side gussets have at least one portion having a second longitudinal length, which is longer than the first longitudinal length and shorter than a length of the second panel. The second panel of the tube is folded along a latitudinal fold line between the top line of the first panel and the top line of the tube so as to form the closed end. The opening is cut in the closed end.

A liner for use with a fluid dispensing vessel. The liner includes a flexible pouch defining an interior region and configured to be placed in a fluid dispensing vessel. The pouch includes a top end that is partially sealed and that includes a first opening. The pouch includes a fluid passageway defined by at least two sealed boundaries and that leads from the opening to the interior region. The pouch includes a bottom end that includes a second opening. The liner includes a fluid dispensing fitment connected to the pouch and configured to be in fluid communication with interior region via the second opening. When fluid is poured into the interior region of the pouch through the opening, it can be dispensed from the pouch through the fitment.

The present invention is directed to a method forming a bottom-gusseted package, wherein each package includes an inwardly-extending, pleat-like gusset at the bottom of the package. To permit heat-sealing formation of each package, the sleeve from which each gusset is formed comprises a lamination of two differing polymeric materials, so that only an exterior surface of each sleeve exhibits the desired heat- sealing characteristics. To facilitate package formation, the sleeves from which the bottom gussets are formed are maintained in a temporarily closed or sealed configuration during package formation by providing a preferably frangible bond or seal at the edge of each sleeve. This result is preferably achieved by folding the laminate material, and temporarily sealing or joining an outer layer of the laminate material from which gusset is formed, while an inner layer is maintained in an unsealed condition.

A method (100) for making a flat bottom bag (800) with a valve (28) is provided. The method (100) includes overlapping and sealing the two longitudinal edges (11a and 11b) of a web (10) to form a continuous tube (12). The method includes cutting-off the continuous tube into tube pieces (14) in accordance with desired bag length such that each tube piece (14) has at least a first open end (18) and a second open end (22). The method (100) includes forming a first pair of flaps (F1, F2) and a second pair of flaps (F3, F4) on the first open end (18) and the second open end (22) respectively. The method (100) includes providing a valve (28) on the second pair of flaps (F3, F4) on the second open end (22). The method (100) includes folding and flattening both the pairs of flaps (F1, F2 and F3, F4) so that the edges of the flaps meet at the centre. The method (100) includes sealing a pre-cut cover patch (30) onto the folded and flattened pairs of flaps (F1, F2 and F3, F4) to close the open ends (18, 22).

A flexible container (10) is provided. The flexible container (10) includes four panels (18, 20, 22, 24). The four panels form a body portion (47); a neck portion (30), and a flare portion (50) that extends from the neck portion (30); a tapered transition portion between the body portion (47) and the neck portion (30); and the neck portion (30) has a reduced width. The flare portion (50) has an expanded end (51). The width of the flare portion (50) gradually increases from the neck portion (30) to the expanded end (51).

The present invention provides a method of making re-closable package (10) and a product made therefrom. The said method comprises providing a first web (46) and a second web (50), folding a predetermined portion (P) of the first web (46) into a V-shape (58) thereby forming an extended portion and cutting the V-shape (58) of the first web (46) to form a pair of extended panels (62). A re-closable zipper (42) sealed with the extended panels (62). The first web (46) sealed with the second web (50) at a first sealing zone (SZ1) and second sealing zone (SZ2). Subsequently, cut the first web (46) and the second web (50) at the first sealing zone (SZ1) thereby obtaining a re-closable package (10). The said re-closable package (10) comprising a first panel (14), a second panel (18) and optionally side gussets (22, 26) and a bottom gusset (30).
