Abstract
Straight zipper sections are attached to a carrier tape for attachment to the mouth end of a bag. The straight zipper sections are mounted on the continuous tape in longitudinal series orientation, or in spaced side-by-side orientation across the length of the tape. The tape in either case may be fan folded and packed into a storage or shipping container. The tape provides for closing attachment across the mouth of a bag to provide a security membrane and/or a tamper evident structure required to be ruptured to gain initial access into the bag after the zipper is opened.

A bag and reclosable zipper assembly, comprising:
- a bag having opposite walls in a generally J-fold orientation with edges in offset relation and defining a mouth;
- a carrier tape having opposite longitudinal edge portions, and means securing said opposite edge portions to respectively said offset wall edges;
- straight substantially coextensive first and second extruded plastic zipper strips, each of which has a base flange of substantial width and with a respective zipper profile along one edge of the base flange complementary to the zipper profile of the other of said zipper strips;
- said base flange of said first zipper strip extending in one lateral direction from its profile;
- said base flange of said second zipper strip extending in opposite lateral direction from its profile and relative to said base flange of said first zipper strip;
- said zipper profiles facing toward one another and being releasably interlocked;
- said oppositely extending base flanges lying in a substantially parallel relation on said carrier tape;
- means securing edges of said base flanges remote from said zipper profiles permanently to said carrier tape adjacent to said means securing said opposite edge portions of the carrier tape to said offset bag wall edges in such a manner that the assembly lies substantially flat;
- and
- said carrier tape providing a rupturable sealing membrane in the span thereof between said zipper strip base sealing means.
