ABSTRACT:
A storage bag having a recloseable mouth, which is biased into an open configuration, is disclosed. The bag, typically manufactured from thermoplastic material such as low-density polyethylene, includes first and second adjacent layers joined or folded along bottom and side edges. The top edges are not folded or permanently joined, but are provided with closure members such as mating male and female zipper strips. The bag is further provided with structure to bias the top edges apart from one another thus biasing the mouth of the bag into an open configuration. The closure members are sufficiently strong to overcome the force of the biasing structure and thereby hold the bag closed when the closure members are engaged. However, upon disengagement of the closure members the biasing structure forces the bag top edges apart to thereby place the bag into an open mouth configuration.
