A bottom-gusseted package comprises a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Optionally, the individual sleeve portions can be configured such that when the flexible web is cut to form individual packages, and each individual sleeve is be cut to form a bottom gusset in one package, and a top sleeve portion in an adjacent package.

A bottom-gusseted package comprises a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Cooperating heat-sealing jaws, including cooperating U-shaped sealing surfaces, act to integrate and seal each individual sleeve with the flexible web to form the bottom gusset of each package, with the heat-sealing jaws preferably configured to include cooperating top sealing surfaces for simultaneously forming a top seal in an adjacent one of the packages.

A horn (2) for an ultrasonic welder includes a pattern of knurls (6) on a face (4) of the horn (2). The knurls (6) are spaced by a pattern of indentations (8, 10) including fist indentations (8a, 10a) formed a first depth from a contact plane and second indentations (8b, 10b) formed a second depth from the contact plane.

The invention provides a pouch container which is excellent in a design property as well as being excellent in a self-standing stability and a shape retention property, can be volume-reduced, can prevent an adhesive agent from seeping into the content even in the case of using a multilayer film material employing the adhesive agent, and can sufficiently secure a sealing performance between the body side end part joint portion and a closing member. In a self-standing pouch container (1) provided with a body member (4) which is made of a film material, and a lower end closing member (5) which closes one end opening portion of the body member (4) in a liquid tight manner and is made of a film material, an annular body side end part joint portion (4a) is formed in one end portion of the body member (4) by being bent inside, and an inside member (6) and an outside member (7) are provided as the lower end closing member (5), the inside member (6) being fusion bonded to an inner surface side of the container in the body side end part joint portion (4a) and the outside member (7) being fusion bonded to an outer surface side of the container.
