ABSTRACT A reclosable bag made from a thin web plastic extrusion has a bag or pouch portion at the top of which an integral return bent gusset provides upwardly projecting multi- ply flanges by which separable resilient zipper-type fastener profiles comprising integral parts of the plastic extrusion are adapted to be pulled apart by pulling the flanges sway from one another. The downwardly projecting portion of the gusset initially may provide an unbroken hermetic seal for the bag or pouch. Where preferred the gusset may be of sufficient length relative to the location of the separable resilient fastener to provide an infolded pouring funnel spout after the spout has been withdrawn or projected from the top opening from the bag and the tip of the spout has been opened. On the other hand, the infolded gusset may serve simply as a hermetic sealing web adapted to be ruptured for dis- charge of contents from the bag. After opening of the bag. It is adapted to be reclosed by securing the resilient separable fastener profiles together.
