ABSTRACT:
A fastener assembly has two sets of fastener profile elements for a reclosable bag especially adapted for mutually facilitating alignment and interlocking closure interengagement of said fastener profile elements responsive to closing pressure applied from outside of the bag toward the fastener assembly.
Further, the fastener assembly is so constructed that a lower portion of the fastener assembly effectively resists opening separation from the interlocking interengagement thereof by separating forces exerted on the wall panels of the bag from inside of the bag body, while the upper portion of the fastener assembly is adapted to be relatively easily separated by pulling apart pull flanges extending thereabove, and such pulling apart of the pull flanges sequentially thereafter being adapted to pull apart the lower portion of the fastener assembly for access through the mouth of the bag into the interior of the bag.
