<p>A reclosable bag (10) including front and back walls (16, 18), and a profile strip fastener assembly (26) sealingly mounted on the inside surface of the front wall, and a one-way vent (58) incorporated into the profile strip fastener assembly. The profile strip fastener assembly includes releasably interlocking profile strips (28, 30), with a secondary peelable seal (48). The reclosable bag includes a frangile joint (52) aligned with the fastener assembly (26) for gaining access to the assembly. The profile strips (28, 30) are continuously sealed to the front wall of the bag around the frangible joint, except for a gap (60) which in part defines the vent (58). Gas pressure evolved within the bag is relieved through the vent (58), while a portion of the profile strips or bag wall closes the gap to prevent air from passing into the bag.</p> |
