Reclosable bag having a loud sound during closing

A zipper for a reclosable bag that generates audible sound therealong when interlocked, the zipper comprising:

• an elongated groove profile defining an opening;
• 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,
• wherein the elongated rib profile defines a stem extending from a base,
• wherein the plurality of first segments define a first enlarged head portion extending from the stem, and the plurality of second segments define a second enlarged head portion extending from the stem,
• wherein the stem is substantially unchanged between the first and second segments,
• wherein the first enlarged head portion has larger cross-sections than the second enlarged head portion,
• wherein the first enlarged head portion has a length perpendicular to its cross-section that is shorter than a length of the second enlarged head portion perpendicular to its cross-section;
• and
• wherein an audible clicking sound of at least 50 dB on average is created during closing by inserting the rib profile in the opening.

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 opening, the closure mechanism including:
• i) an elongated groove profile having two arms which form a general U-shape to define an opening to a channel;
• and
• ii) an elongated rib profile opposing the groove profile, the rib profile including a stem, wherein a plurality of first segments define a first enlarged head portion extending from the stem, and a plurality of second segments define a second enlarged head portion extending from the stem, wherein the plurality of first segments alternate with the plurality of second segments to create a structural discontinuity 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, wherein the stem is substantially unchanged between the first and second segments, wherein the first enlarged head portion has larger cross-sections than the second enlarged head portion, wherein the first enlarged head portion has a length perpendicular to its cross-section that is shorter than a length of the second enlarged head portion perpendicular to its cross-section, and wherein the first enlarged head portion has a width about three times a width of the opening.
