1. A closure mechanism comprising:
a first elongate closure member that includes a series of regularly spaced features being disposed along an entire length of the first elongate closure member, the series of regularly spaced features including a plurality of vertically extending elongate features on an outer surface of the first elongate closure member, the vertically extending elongate features being spaced apart along the entire length of the first elongate closure member in alternating and repeating distances; a second elongate closure member that includes a series of regularly spaced features being disposed along an entire length of the second elongate closure member, the second elongate closure member being configured to sealingly engage the first elongate closure member; and a slider that slides along the first and second elongate closure members to engage or to separate the first and second elongate closure members, wherein the slider interacts with (i) the series of regularly spaced features on the first elongate closure member to produce a first feedback at a first frequency, and (ii) the series of regularly spaced features on the second elongate closure member to produce a second feedback at a second frequency, the first and second feedbacks being produced when the slider is slid along the first and second elongate closure members, and wherein the spacing of (i) the regularly spaced features of the series on the first elongate closure member and (ii) the regularly spaced features of the series on the second elongate closure member are different from each other such that the first and second frequencies are different from each other. |
