摘要:
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 bottom and side gusseted package comprises a package body, a pair of inwardly extending side gussets, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the 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 inwardly extending side gussets are formed, and the flexible web is cut to form individual packages, such that each individual sleeve forms a bottom gusset in a respective one of the gusseted packages.

A package (10) having a recloseable pour spout (28) is disclosed, with the package including front and rear package panels (12,14) which may be joined at respective side edges thereof by inwardly extending side gussets (16,18). An upper edge portion of the package is removable, including one of the side gussets, to form a pour spout (28) for dispensing the contents of the package. A fastener strip (30), which can be detachably connected to itself, extends between confronting inside surfaces of the front and rear package panels (12,14), adjacent to the pour spout (28), whereby the pour spout can be conveniently closed after the package is initially opened. The package can include a longitudinal seal (40) which extends from adjacent the pour spout (28) to overlap the fastener strip (30); When the package includes side gussets, the package may include an arrangement of corner seals, with the corner seals at the one of the gussets at which the package pour spout is formed not extending the full length of the package, thereby desirably facilitating shaping of the package to form the pour spout. A method of forming the present package is also disclosed.

A method of forming a bottom-gusseted package comprising a package body (112), a bottom gusset (120) and a top sleeve portion (124') 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 said bottom gusset in a respective package and cut of sleeve material positioned to form a top sleeve portion in a respective adjacent package.
