Abstract
A zipper for a reclosable bag including 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 a structural discontinuity along a length thereof, wherein during interlocking 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 at least one of the second elongated groove profile and the second elongated rib profile is shaped differently as compared to the elongated groove profile and the elongated rib profile, respectively.

A method for making a reclosable pouch defining an interior, comprising:
- continuously extruding a longitudinally extending first zipper profile, the first zipper profile defining a first elongated groove profile having two arms which form a general U-shape to define an opening to a channel;
- continuously extruding a longitudinally extending second zipper profile, the second zipper profile defining a first elongated rib profile;
- intermittently deforming the second zipper profile to form alternating first and second segments of the first elongated rib profile, the second segments having a smaller cross-section when viewed perpendicular to a length of the rib profile than the first segments and the second segments being longer than the first segments;
- continuously extruding a longitudinally extending third zipper profile, the third zipper profile defining a second elongated groove profile;
- continuously extruding a longitudinally extending fourth zipper profile, the fourth zipper profile defining a second elongated rib profile;
- intermittently deforming the fourth zipper profile to form alternating first and second segments of the second elongated rib profile,
- wherein at least one of the first elongated groove profile and the first elongated rib profile is shaped differently as compared to the second elongated groove profile and the second elongated rib profile, respectively, the method further comprising;
- affixing each of the first and second elongated groove profiles and the first and second elongated rib profiles to one of a first wall and a second wall so that the first elongated groove profile and the first elongated rib profile are on opposite walls and the second elongated groove profile and the second elongated rib profile are on opposite walls;
- and
- joining the first and second walls along three sides.
