Abstract: A zippered bag includes two sheets sealed to each other along a plurality of edges to form opposing bag sides. The bag also includes a first fastener strip including an inner wall and an outer wall hinged to the inner wall, with the first fastener strip being attached to one of the opposing bag sides. The inner wall includes a first profile. A second fastener strip includes a second profile, the second fastener strip being attached to the other one of the opposing bag sides. The first and second profiles are adapted to interlock to close the bag, wherein the first and second profiles each include an uppermost closure element, an intermediate closure element, and a bottommost closure element. A slider straddles the first and second fastener strips such that the uppermost, intermediate, and bottommost closure elements are enclosed by the slider and the slider is movable between a closed position and an open position.
