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.

First claim

What is claimed is:

1. A container including:
a front panel and a rear panel;
a first gusset joining a first side of said front panel to a first side of said rear panel;
a second gusset joining a second side of said front panel to a second side of said rear panel;
wherein the front panel, the rear panel and the first and second gussets are formed from a single sheet of material, wherein lateral edges of said single sheet of material are sealed together by a fin seal;
an opening being formed by an edge of said front and rear panels and said first and second gussets;
a self-mating zipper sealed to an interior of said front and rear panels and said first and second gussets, extending around an entire interior periphery of the container, downwardly adjacent from said opening, the fin seal maintaining ends of the zipper proximate to each other, the self-mating zipper being oriented in a transverse direction along said single sheet of material, ends of the self-mating zipper being proximate to corresponding lateral edges of said single sheet of material;
wherein said self-mating. zipper includes a single web with plurality of engaging track elements each track element including a stern and an enlarged engaging head, the enlarged engaging heads extending continuously around an entire periphery of the container, parallel to said opening, whereby a first portion of said single web can engage a second portion of said single web in a plurality of different configurations and thereby through a plurality of alignments; and
wherein said sell-mating zipper provides a first closed position and a second closed position for the container, the first closed position including the first and second gussets folded inwardly and positioned between the front and rear panels, the second closed position including the first and second gussets folded outwardly and extending outwardly from edges of the front and rear panels.

2. The container of claim 1 wherein said front panel, said first gusset, said rear panel and said second gusset are separated by successive folds formed in said single sheet of web, and further wherein said first gusset and said second gusset include central folds therein.

3. The container of claim 1 wherein said plurality of engaging track elements includes at least three engaging track elements.

4. The container of claim 1 wherein ends of said zipper abut each other.

5. A container including:
a front panel and a rear panel;
a first gusset joining a first side of said front panel to a first side of said rear panel;
a second gusset joining a second side of said front panel to a second side of said rear panel;
wherein the front panel, the rear panel and the first and second gussets are formed from a single sheet of material, wherein lateral edges of said single sheet of material are sealed together by a fin seal;
an opening being formed by an edge of said front and rear panels and said first and second gussets;
a single self-mating variable alignment multi-track zipper web sealed to an interior of said front and rear panels and said first and second gussets, wherein track elements of the single self-mating variable alignment multi-track zipper web include a stern and an enlarged engaging head, and the enlarged engaging heads extend continuously around an entire interior periphery of the container, downwardly adjacent from and parallel to said opening, the fin seal maintaining ends of the zipper web proximate to each other, the self-mating zipper being oriented in a transverse direction along said single sheet of material, ends of the self-mating zipper being proximate to corresponding lateral edges of said single sheet of material; and
wherein said self-mating zipper provides a first closed position and a second closed position for the container, the first closed position including the first and second gussets folded inwardly and positioned between the front and rear panels, the second dosed position including the first and second gussets folded outwardly and extending outwardly from edges of the front and rear panels.

6. The container of claim 5 wherein said front panel, said first gusset, said rear panel. and said second gusset are separated by successive folds formed in said single sheet of web, and further wherein said first gusset and said second gusset include central folds therein.

7. The container of claim 5 wherein said zipper web is a single strip.

8. The container of claim 5 wherein said variable alignment zipper web includes at least three engaging track elements.

9. The container of claim 5 wherein said variable alignment zipper web includes at least six engaging track elements.

10. The container of claim 5 wherein the ends of the zipper are sealed proximate to corresponding lateral edges of the single sheet of material, and wherein at least one end of the zipper extends into the fin seal.
