FASTENER

摘要

A reclosable fastener includes an insert element and a retention element. The retention element has a plurality of discrete, spaced projections extending generally orthogonally from at least one side edge of one of the opposing surfaces. At least one of the projections has a free end that includes a hook portion extending generally orthogonally from the projection toward the central longitudinal axis. The fastener operates in first an second conditions. In the first condition, the fastener is open and the insert element is disengaged from the retention element, and in the second condition the fastener is closed and the insert element engages the retention element. In moving from the first condition to the second condition, the insert element engages the retention element by overlaying onto the retention element and being pressed into place. In moving from the second condition to the first condition the insert element disengages from the retention element by peeling from the retention element.
