Abstract:
The present disclosure relates to a packaging system for compressible goods utilizing pre-punched alignment apertures on wicketed and/or chain-linked open bottom bags. The disclosure relates to a bag transport and indexing system through the form fill compress and seal system. The disclosure further relates to the use of sprocket pins spaced accordingly on either a horizontal linear or rotary machine so that the sprockets correspond to the pre-punched apertures on the wicketed and/or chain-linked open bottom bags.
Abstract:
The disclosure relates to a method and apparatus for compressing woven material or other compressible material, such as, but not limited to, a comforter set or bedding set. The compressible goods are engaged by a gantry system, compressed, and loaded vertically into the open bottom of a vertically oriented inverted bag, wherein the bags are typically configured as a chain of such bags. The compression step drives out a substantial portion of the air from the bag. The bags are then sealed. The closed bottom of the bag may include a closed zipper configuration, possibly in combination with a peel seal.
Abstract:
The present disclosure relates to the use of coextruded or integral sealing ribs on zipper flanges to enhance the quality of the sealing between the flanges and the walls of a reclosable package. The coextruded sealing ribs may be made from sealing resins or similar materials. Additionally, grip strips are placed on the opposite side of the flanges from the ribs in order to improve the quality of the sealing even further and to inhibit inner flange sealing.
Abstract:
A security zipper (10) is provided, which includes a consumer side zipper pair (14, 20) and a product side zipper pair (16, 22), where each zipper pair is capable of secure mating. Between the zipper pairs is an intermediate flange pair (28,30) which is layered with an adhesive as well as an adhesive enhancer to securely connect the intermediate flange pair. A slider (74) is provided over the consumer side zipper pair, the product side zipper pair and the intermediate flange pair which mates the zipper pairs and connects the intermediate flanges so that the zipper is securely closed.
Abstract:
The disclosure relates to a method and apparatus for compressing woven material or other compressible material, such as, but not limited to, a comforter set or bedding set. The bedding set or other woven material is placed into a reclosable storage bag which includes a reclosable zipper and a reclosable air valve. With the zipper open, the bag is compressed by a compression apparatus, typically in the absence of vacuum being applied, and, thereafter, the zipper is closed. Straps are wrapped around the compressed bag and the compressed bag is placed into a tote container or similar device. The result is a package with reduced volume, which reduces shipping and display costs, and is more aesthetically attractive to the consumer.
Abstract:
A reclosable bag that can be hermetically sealed. The bag comprises a pair of zipper strips that are joined in respective zones without substantial deformation of the longitudinal profiled closure elements. These zones of zipper strip joinder assist in providing a leakproof transition from the openable section of the zipper to the corner seals, where the longitudinal profiled closure elements are either substantially deformed (e.g., crushed) or absent. The method of manufacture involves the steps of ultrasonically welding a wide area and then thermally crushing a narrower area overlapping the wide welded area to form leakproof zipper joints. This method can be applied to string (flangeless) zippers as well as flanged zippers.

A slider is provided over the consumer side zipper pair, the product side zipper pair and the intermediate flange pair which mates the zipper pairs and connects the intermediate flanges so that the zipper is securely closed. A bag is also disclosed, which includes the security zipper and a connected product side pouch. In addition, a method for manufacturing the bag is disclosed.
Abstract:
The water-resistant or waterproof zipper includes first and second profiles which are interlocked or separated by the movement of a slider. The first sidewall of the slider is generally planar while the second sidewall is generally curved so that the sidewalls are relatively closer together at the closing end and generally further apart at the opening end. A triangular island and separating plow are formed at the opening end to separate the first and second profiles. The slider includes various channels which engage corresponding rails in the profiles in order to properly position the profiles. The slider further includes various protrusions and a flange to properly position the profiles.
