Abstract

A reclosable bag for filling with at least one food product.
The reclosable bag generally includes at least one sheet of web material having at least two areas of structural weakness.
At least one fold structure is located between and defined by the two areas of structural weakness. An opening is located generally opposite the fold structure. The reclosable bag further includes a reclosable fastener structure having an integral skirt structure of skirt web material, including a distal margin, extending therefrom. The distal margin is coupled to the web material at, at least one location between the areas of structural weakness and the opening. The reclosable fastener structure extends past the areas of structural weakness and into the fold structure. The reclosable bag is capable of being filled with at least one food product through the opening.

5. A reclosable bag as defined in claim 1, additionally comprising:
a slider which is slidably mounted on said two releasably engageable fastener members between opposite ends of said releasably engageable fastener members to selectively engage said releasably engageable fastener members together and disengage said releasably engageable fastener members, thereby respectively closing and opening said reclosable bag.
6. A reclosable bag as defined in claim 1, wherein said skirt web material is integral with said reclosable fastener structure.
7. A reclosable bag as defined in claim 1, wherein said skirt web material is coupled to said reclosable fastener structure.
8. A reclosable bag as defined in claim 1, wherein said integral skirt structures include each an outside surface and an inside surface, said distal margins being located on said outside surfaces, said inside each surfaces including a predetermined area having a releasable adhesive material disposed thereon, whereby a peelable seal may be formed between said inside surfaces.
9. A reclosable bag as defined in claim 8, wherein said peelable seal, when formed, is hermetic.
10. A reclosable bag as defined in claim 1, wherein said opening is located generally opposite said fold structure.
11. A reclosable bag as defined in claim 1, wherein said barrier comprises:
barrier web material which extends between and is coupled to said sidewall structures.
12. A reclosable bag as defined in claim 1, wherein said barrier comprises:
a first barrier web segment extending from said distal margin of said integral skirt structure of said first releasably engageable fastener member;
a second barrier web segment extending from said distal margin of said integral skirt structure of said second releasably engageable fastener member;
a peelable seal located between said first and second barrier web segments.
13. A reclosable bag as defined in claim 1, wherein said barrier comprises:
barrier web material extending between said distal margin of said integral skirt structure of said first releasably engageable fastener member to from said distal margin of said integral skirt structure of said second releasably engageable fastener member;
an area of structural weakness located in said sheet of barrier material at a location intermediate said first and second releasably engageable fastener members.
14. A reclosable bag as defined in claim 13, wherein said area of structural weakness comprises a hermetic seal.
15. A reclosable bag for filling with at least one food product, said reclosable bag comprising:

at least one sheet of web material defining: a front panel having a top, a bottom, and sides; and a rear panel having a top, a bottom, and sides, said tops and said sides of said front and rear panels being coupled together, an opening being located between said bottoms of said front and rear panels;
an area of structural weakness located in each of said front and rear panels below said tops of said front and rear panels and extending between at least a substantial portion of said sides of said front and rear panels; and a reclosable fastener assembly comprising first and second interlockable fastener members each having a skirt structure of skirt web material extending downwardly therefrom, said skirt structures each including a distal portion, said distal portion of said skirt structure of said first fastener member being coupled to said front panel below said area of structural weakness located in said front panel, said distal portion of said skirt structure of said second fastener member being coupled to said rear panel below said area of structural weakness located in said rear panel;
