Abstract: 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.

Abstract: 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.

Abstract: According to the invention, a patch is provided to be attached to the outside of the wall of the bag over the profile strip fastener assembly that is attached to the front panel of the package. The patch is made from a gas barrier type of substrate as to prevent oxygen and other gases from entering or leaving the perforations within the opening feature used to access the fastener assembly. The side of the patch that is in contact with the front panel of the bag includes an adhesive for securement to the package. A variety of adhesives can be utilized for securement depending on the arrangement of the perforations. Printing can be included on the outside of the patch to highlight the reclosable feature of the package thereby eliminating the need to modify the original printing on the package.

Abstract: A method of making a recloseable package having a slider zipper assembly includes advancing a web of a plastic film material in a direction along a longitudinal axis thereof, and applying a plurality of profile strip fastener assemblies to the plastic film material transversely of the longitudinal axis. A slider is applied to each of the fastener assemblies so that movement of each slider along the length of the respective one of the fastener assemblies moves the pair of profile strips thereof into and out of interlocking engagement. Opposite side edges of the plastic film material are joined to form a tube, with seals formed transversely of the tube to form a top seal and a bottom seal for each of the packages. The package is configured such that the slider projects generally through the front wall of the package, with the front wall optionally being provided with a frangible region in the form of a line of weakness aligned with the fastener assembly.

Abstract: A recloseable bag includes a bag body having a first wall and a second wall connected together substantially around proximate perimeters. The bag includesa first openable joint formed as perforations through the first wall and a patch secured to the first wall over the first openable joint. The patch has a second openable joint formed as perforations in registry with the perforations of the first openable joint. The patch can be composed of a material that tears in a controlled fashion along the perforations of the second openable joint. A zipper arrangement can be sealed to the inside surface of the patch.

Abstract: A levee gate and the process for the production thereof. The levee gate of the invention includes a rectangular sheet of thermoplastic material with a rectangular sleeve located on one edge of the thermoplastic material, the rectangular sleeve being a portion of the rectangular sheet fused to the rectangular sheet. The process for the production of the levee gate includes extruding a cylindrical tube of thermoplastic material, inflating the cylindrical tube as it is extruded to provide an inflated length of tube, flattening the inflated length of tube without fusing the opposed walls of the tube to each other, and continuously fusing a portion of the opposed walls together to form a seam.
