Abstract:
1. A zipper for a reclosable bag comprising: an elongated groove profile having two arms with distal hooks which form a general U-shape to define an opening to a channel; and an elongated rib profile opposing the groove profile and defining opposing elongated notches to engage the distal hooks along an entire length of the elongated rib profile, wherein the rib profile defines a stem extending from a base and terminating in an arrow shaped head with a widest part of the arrow shaped head being adjacent the stem to form the opposing elongated notches, wherein a plurality of first segments of the rib profile alternate with a plurality of second segments having a similar shape to the first segments but smaller cross-sections in height and width to create a structural discontinuity along a length thereof, wherein the stem is substantially unchanged between the first and second segments, wherein the arrow shaped head is deformed in the second segments such that the widest part is: at least 15% smaller in the second segments compared to the first segments; no more than 50% smaller in the second segments compared to the first segments; at least 5% wider than the stem in both segments; and, in the first segments, about three times bigger than the opening, wherein the first segments having shorter lengths than the second segments such that interlocking the groove and rib profiles creates the audible clicking sound when the groove and rib profiles are engaged along the entire length of the elongated rib profile, and wherein when the groove and rib profiles are interlocked, contact points between the stem and the distal hooks are created for sealing the zipper.
