ABSTRACT:
A package in the form of a reclosable bag includes a bag body including front and back walls, and a profile strip fastener assembly sealingly mounted on the inside surface of the front wall, and a one-way vent incorporated into the bag sealing arrangement. The profile strip fastener assembly includes a pair of releasably interlocking profile strips, with a secondary, peelable seal provided between the profile strips apart from their mechanically interlocked portions. The bag body preferably includes a frangible joint substantially aligned with the fastener assembly for gaining access to the assembly, with the frangible joint desirably providing tamper-evidence of opening of the package. The profile strips are sealed to the front wall of the bag body with a continuous oval shaped seal around the frangible joint, except for a gap which in part defines the vent. Gas pressure caused by evolving gas within the bag is relieved through the vent, while a portion of one of the profile strips or a portion of the bag wall, unsecured across the gap closes the gap to prevent air from passing into the bag.
