Abstract: This invention is directed to an improved reclosable bag having first and second walls and an open top. The open top has first and second flexible fastener strips attached thereto. One of the strips has a profile portion forming a groove; the other strip has a profile portion forming a rib with a portion of the rib received and retained in the groove when the bag top is closed. Each of the fastener strips has a base connected to the respective walls. The bag has a slider mounted on the fastener strips which is movable longitudinally along the fastener strip to progressively separate the rib from the groove to open the bag, and is movable in the opposite direction to progressively return rib to a retained condition in the groove and create a leak-proof seal. A cradle is formed near one end of the fastener strip which is sized, constructed and arranged to receive and retain the base of the slider when the fastener strip is sealed to prevent leakage from that end of the fastener strip.
