Abstract:
1. A product bag comprising: a main body bag comprising a pinch-bottom bag having a predetermined longitudinal extent wherein first and second sheet members have substantially the same length dimensions but are longitudinally offset with respect to each other so as to effectively form end flap members at opposite ends of said main body bag portion, wherein each end flap member of one of said first and second sheet members comprises a transversely extending edge portion to be folded over onto external surface portions of the other one of said first and second sheet members and secured to said external surface portion of said other one of said first and second sheet members as a result of at least one of said end flap members of a first one of said first and second sheet members being adhesively bonded to said external surface portion of said second one of said first and second sheet members, and wherein further said main body bag comprises a gusseted bag wherein opposite sides of said product bag comprise folded pleated portions; wherein said folded pleated portions of said opposite sides of said product bag comprise a single set of tab members which extend transversely and outwardly from opposite sides of said end flap member of a first one of said first and second sheet members forming one of said folded pleated portions such that a transversely extending edge portion of each one of said tab members is coincident with said transversely extending edge portion of said flap member, and wherein, after said end flap member of said first one of said first and second sheet members has been folded over said second one of said first and second sheet members, said single set of tab members, extending transversely outwardly from opposite sides of said end flap member of said first one of said first and second sheet members, can be folded transversely inwardly so as to wrap around said opposite sides of said second one of said first and second sheet members so as to engage said external surface portion of said first one of said first and second sheet members; and a closure strip folded over upon itself such that a first portion of said folded closure strip is adhesively bonded to an external surface portion of one of said first and second sheet members within the vicinity of said normally open end of said main body bag portion, while a second portion of said folded closure strip is adhesively bonded to an external surface portion of the other one of said first and second sheet members within the vicinity of said normally open end of said main body bag portion so as to envelop said inwardly folded tab members and thereby close and seal said normally open end of said main body bag portion.
