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 extending therefrom. The integral skirt structure includes a distal margin. 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 capable of being filled with at least one food product through the opening.

Dependent claims

A reclosable bag for filling with at least one food product, said reclosable bag comprising:

a single sheet of web material comprising a fold transversely located therein at a position between first and second ends of said single sheet of web material, two areas of structural weakness on opposite sides of said fold, and an opening defined between said first and second ends of said single sheet of web material, wherein said areas of structural weakness are integral to said single sheet of web material;
and
a reclosable slider fastener structure comprising two interlockable fastener tracks each having a skirt structure of skirt web material extending downwardly therefrom and a slider mounted on the tops of said interlockable fastener tracks, said reclosable slider fastener structure being located within said fold, wherein opposite ends of said interlockable fastener tracks are sealed together, thereby retaining said slider thereupon, and wherein said slider is moveable on said interlockable fastener tracks between said opposite ends of said interlockable fastener tracks to selectively engage and disengage said interlockable fastener tracks to respectively close and open said reclosable bag, and wherein said areas of structural weakness extend in a direction which is generally parallel to said reclosable slider fastener structure and are being located below said slider adjacent said skirt structures;
said skirt structures each including a distal margin, wherein said distal margins of said skirt structures are releasably coupled to each other by a releasable and resealable adhesive material;
said distal margins of said skirt structures being respectively coupled to said single sheet of web material at opposing locations respectively located between said areas of structural weakness and said opening, said interlockable fastener tracks and said slider extending into said fold beyond said areas of structural weakness;
said reclosable bag being capable of being filled with at least one food product through said opening.
