Abstract: Disclosed is a zipper for a reclosable thermoplastic bag having opposing rib and groove profiles wherein at least one of the opposing zipper profiles has an longitudinally extending part interlockable and substantially free of interdigitation with the opposing profile and wherein the part is structurally discontinuous along its length. When the rib and groove profiles are interlocked, an audible clicking sound and/or a vibratory or bumpy feel perceptible to the touch is imparted.Further disclosed is a process and apparatus for making the zipper wherein a zipper profile is extruded and indentions are formed within and along it.

Abstract: An apparatus for clamping, folding and transferring a stack of flexible plastic bag products such as a stack of zippered plastic bags.

Abstract: A reusable adhesive closure including an adhesive strip affixed transversely across a first inner surface of a front wall of a bag at a preselected distance from the opening of the bag; and a first roughened surface strip positioned transversely across a second inner surface of a rear wall of the bag aligned on the wall opposite from the adhesive strip. The first roughened strip is an integral portion of the wall of the bag. The roughened strip is pressable against and into the adhesive strip, whereby a seal is formed by contacting the adhesive strip with the flexible flap member.

Abstract: An adhesive closure including an adhesive strip affixed transversely across a first inner surface of a front wall of a bag at a preselected distance from the opening of the bag; and a flexible flap member strip affixed transversely across a second inner surface of a rear wall of the bag aligned on the wall opposite from the adhesive strip. The flexible flap member is attached to the inner surface of the wall along one edge of the flexible flap member. The flexible flap member is pressable against and into the adhesive strip, whereby a seal is formed by contacting the adhesive strip with the flexible flap member. The flexible flap member is adapted to provide a shear opening force from the inside of the bag when the flap member is contacting the adhesive strip, and adapted to provide a peel opening force from the outside of the bag when the flap member is contacting the adhesive strip. The peel opening force is smaller than the shear opening force, thereby providing an enhanced burst strength to the bag.

Abstract: A reclosable fastener assembly having two interlocking profiles with uppermost closure elements and bottommost closure elements and a slider for moving between a closed position and an open position along the profiles in straddling relation. The slider has a top and side walls depending from opposite sides of the top for receiving the profiles therebetween. The side walls extend downward from the top to a point at or below the profiles, and the side walls extend from a separating end of the slider to a pinching end. The side walls have a greater spacing at the separating end than at the pinching end, but close enough at the pinching end to press the first and second profiles into an interlocked relationship as the slider is moved toward the closed position. The slider has a separating leg depending from the top between the first and second side walls at the separating end of the slider.

Abstract: A closure member for a reclosable thermoplastic bag having opposing rib and groove profiles wherein the rib profile has an longitudinally extending part interlockable and substantially free of interdigitation with the opposing groove profile and wherein the part is deformed defining indentions in the part to provide structural discontinuity along its length. When the rib and groove profiles are interlocked, an audible clicking sound and/or a vibratory or bumpy feel perceptible to the touch is imparted.

Abstract: The present invention relates to a self-foaming, self-leveling aqueous liquid composition packagable in a non-pressurized deformable dispenser of flexible barrier material adapted to contain, maintain and dispense a proportioned amount of the cleansing composition under positive pressure. The composition comprises: a major amount of water; a surfactant; and a dual purpose pressure agent comprising at least one aliphatic hydrocarbon fluid in amounts sufficient to provide the liquid composition, which when contained in a dispenser exerts a positive vapor pressure at least at about 1.6.degree. C. The composition is dispensed as a liquid under normal operating conditions, which liquid foams instantaneously and spontaneously on spreading.

Abstract: A resealable flexible thermoplastic bag including a front wall and a back wall, said walls being joined along the major portions of their opposite longitudinal edges and bottom; an open mouth adjacent to the top edge of said bag; a closure near the open mouth of said bag including an adhesive strip affixed to a first inner surface of one of a front wall or rear wall of a bag at a preselected distance from the opening of the bag; and a first roughened surface strip affixed to a second inner surface of one of a front wall or rear wall of a bag at a preselected distance from the opening of the bag; said roughened surface of said bag being pressable against and into said adhesive strip on said first inner surface, whereby a seal is formed by contacting said adhesive strip with said roughened surface of said second inner surface.

Abstract: A coextruded multilayer film having increased retention of volatile antioxidants and process for making the film. The multilayer film includes an antioxidant layer containing a volatile antioxidant, said antioxidant layer being semipermeable to the volatile antioxidant; and a barrier layer, impermeable to the volatile antioxidant. The film can be produced on a conventional blown film process with the barrier layer coextruded externally to the antioxidant layer. The barrier layer traps the volatile antioxidant inside the tube of the blown film process, reducing the amount of volatile antioxidant migrating from the film.
