Abstract
The invention generally relates to interlocking closure devices including two closure elements arranged to be interlocked over a predetermined length. The closure elements permit the venting of fluids when the closure elements are in their occluded vented position. The closure elements have an occluded closed position which creates a seal and prevents fluids from passing between the interlocking closure elements. The closure fastening device may be utilized with a flexible container and is advantageous in permitting a user to vent excess air from the interior of the flexible container prior to sealing the container.
