Appl. No.:

11/796446

Inventors:

Charles Greco - Bardonia NY, US

David J. Anzini - Middletown NY, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

B65D 33/25
B65D 33/18

US Classification:

24399, 24400, 383 612, 383 613, 3832101

Abstract:

A zipper assembly for a reclosable package or bag is disclosed. The zipper assembly includes two profiles with flanges and internal interlocking elements on the interior of the flanges. The exterior of one of the flanges includes two exterior parallel press-to-close profile-like interlocking elements which are brought into engagement with each other by folding the flanges of the zipper assembly. This increases the burst handling capability of the zipper assembly and the package or bag to which it is attached. Alternatives include substituting a peel seal for the exterior interlocking element as well as an exterior label or sticker to maintain the flanges in a folded configuration.

Illinois Tool Works Inc. - Glenview IL

International Classification:

A44B 19/16

US Classification:

2458512, 24400

Abstract:

The disclosure relates to a reclosable zipper for a package or bag wherein apertures are formed at periodic package-width intervals passing through the interlocking elements of the zipper profiles in order to minimize the mass of zipper material in areas where side seals of packages or bags will be subsequently formed. The otherwise interlocking elements upstream of, or at the trailing edge of, the apertures are deformed so as to prevent interlocking of the elements through a limited area. This allows a separator pin to pass through the area of the apertures and pass between the zipper profiles, eliminating or reducing the collision of the separator with the zipper profiles and subsequent potential damage to the zipper profiles.

International Classification:

B65D 33/16
B65D 33/00
B65D 30/20

US Classification:

383063000, 383120000, 383095000

Abstract:

A reclosable gusseted bag is disclosed wherein a single web multiple alignment zipper is placed around the interior of the mouth of the bag, downwardly adjacent from the upper edge of the front panel, rear panel and side gussets thereby resulting in an increased size of opening as the mouth of the gusseted bag. The use of a single web multiple alignment zipper allows opposing portions of the web to engage each other within a range of alignments thereby allowing for simplified use by the consumer.

Appl. No.:

11/801062

Inventors:

Charles Greco - Bardonia NY, US
Rusty Koenigkramer - Nanuet NY, US

International Classification:

B65D 33/16

US Classification:

383 63

Abstract:

Reclosable gusseted packages or bags have improved resistance to leaking or spilling through the gussets by way of glue or adhesive applied in the gussets in the areas proximate to the reclosable zipper of the bag. This can be done by applying a glue smear to the interior and exterior of the gusset walls; applying glue dots between the exterior facing walls of the gussets; or by applying the glue smear between the exterior facing walls of the gussets.

Appl. No.:

12/435158

Inventors:

Charles Greco - Bardonia NY, US
Eric Plourde - Frankfort IL, US
Rusty Koenigkramer - Nanuet NY, US

International Classification:

B65D 33/16

US Classification:

383 64

Abstract:

Zippers are provided for reclosable packages or bags. By selectively co-extruding a first portion of the zipper with a shrinkable or expandable material, and simultaneously co-extruding a second portion of the zipper with a dimensionally stable thermoplastic or similar material, followed by a step of activating the shrinkage or expansion of the shrinkable material, several different shapes of zipper can be achieved. For instance, by co-extruding the shrinkable material to a lower portion of the zipper or co-extruding the expandable material to an upper portion of the zipper, an upwardly arching or convex shape can be achieved. Similarly, by co-extruding the shrinkable material to an upper portion of the zipper or co-extruding the expandable material to a lower portion of the zipper, a downwardly arching or concave shape can be achieved. Similarly, by co-extruding the shrinkable material to inner portions of the zipper or the expandable material to outer portions of the zipper, a self-opening characteristic may be added to the zipper. Additionally, zippers may be placed at inclined positions in a complementary head-to-head configuration in order to eliminate or reduce waste of packaging material during manufacture.

International Classification:

B65B 51/04
B65B 51/22

US Classification:

53420

Abstract:

The disclosure relates to a method and apparatus wherein extra mass is added to a profile of a slider zipper prior to the ultrasonic or thermal forming of the end stomps. This results in an end stomp of increased size and height, thereby providing a greater resistance to the slider being pulled from the ends of the zipper.

International Classification:

B65B 9/00

US Classification:

53450

Abstract:

The disclosure pertains to the a wide mouth gusseted package wherein four machine direction edge seals are formed on the film, and the zipper is applied in the transverse direction on the opposite side of the film from where the machine direction edge seals are formed. In the resulting package, the edge seals are at the exterior of the four corners of the package, and the resulting gussets can be folded inwardly or outwardly. The package may further include a sealing strip with a peel seal layer and a sealant layer whereby a hermetic package may be produced at higher production rates and lower productions costs.

International Classification:

B31B 39/00

US Classification:

493210

Abstract:

The disclosure pertains to method for manufacturing reclosable packages, bags or pouches wherein, typically, a unisex zipper is looped and sealed inside of the package. The formation of the looped zipper segment causes the package to have a wide open mouth, and a natural tendency toward the open configuration. Both transverse and machine direction methods are disclosed, as well as resulting packages which may include a spout.
