Abstract
A zipper for a reclosable bag includes an elongated groove profile having two arms which form a general U-shape to define an opening to a channel, and an elongated rib profile opposing the groove profile. A plurality of first segments of the rib profile alternate with a plurality of second segments of the rib profile to create a structural discontinuity along a length thereof. During interlocking of the groove and rib profiles, an audible clicking sound of at least 50 dB on average is created during opening and closing.
Claims20
A reclosable pouch defining an interior, comprising:
- a) a first wall;
- b) a second wall opposing and partially sealed to the first wall to form a mouth for access to the interior;
- and
- c) a closure mechanism for selectively sealing the mouth, the closure mechanism including:
- i) a first zipper having:
- an elongated groove profile having two arms which form a general U-shape to define an opening to a channel;
- and
- an elongated rib profile opposing the groove profile, wherein a plurality of first segments of the rib profile alternate with a plurality of second segments of the rib profile to create structural discontinuities along a length thereof such that interlocking the groove and rib profiles creates an audible clicking sound along the entire length of at least 50 dB on average during closing, and wherein the second segments have a smaller cross-section when viewed perpendicular to the length of the rib profile than the first segments and wherein the second segments are longer than the first segments;
- and
- ii) a second zipper inwardly spaced apart from the profiles on the reclosable bag, the second zipper having a second elongated groove profile and a second elongated rib profile,
- wherein the elongated rib profile defines a stem extending from a base, and a head portion, and
- wherein at least one of the plurality of second segments includes an inwardly disposed notch between the stem and the head portion.
