Abstract
A reclosable pouch is provided having front and back walls and an opening along its upper edge. A first fastener profile is sealed on its ends to the exterior of the front wall of the pouch. The fastener profile extends longitudinally near the pouch opening. A second fastener profile is sealed on its ends to the exterior of the back wall of the pouch. The first and second fastener profiles each have a rib member extending longitudinally thereon and a groove for reception of the oppositely disposed rib. The fastener profiles are adapted for interlocking with the front and back walls of the pouch being interposed therebetween. A method and apparatus for manufacturing the aforesaid pouches are also described herein.

A reclosable flexible container comprising:
- a pouch having front and back walls and a pouch opening at the upper edge thereof;
- a first fastener profile disposed on the exterior of said back wall and extending longitudinally thereon proximate said pouch opening;
- a second fastener profile disposed on the exterior of said back wall, said first and second fastener profiles being constructed and arranged for selectively releasable interlocking with said front and back walls of said pouch being interposed therebetween;
- said first and second profile fastener profiles each comprising a strip of flexible plastic material having a base and an interlocking portion projecting from said base;
- and
- each of said fastener profiles having a proximal end and a distal end, said profiles being sealed only at said ends to the exterior of said pouch.
A bag structure comprising:
- a bag body having an open top and bag walls formed of a thin plastic film;
- facing, mating, interlocking fastener profiles formed of a resilient material and extending longitudinally and in parallel to said open top of said bag, each of said fastener profiles having a base sealed to one of the exterior surfaces of said bag walls;
- at least one of said fastener profiles comprising a releasable interlocking rib element extending away from said base and detached from the exterior surface of said bag;
- at least one of said fastener profiles comprising a releasable interlocking groove element extending away from said base and detached from the exterior surface of said bag;
- and
- said fastener profiles having a gap disposed between said rib and groove elements when interlocked, said gap being sized so as to allow one or more layers of film to be interposed between said rib element and said groove element when interlocked, said rib element, groove element and interposed film thereby forming a substantially hermetic seal of said bag while at the same time being openable by manually drawing said rib and groove elements apart.
