Closure mechanism with multiple frequency feedback

A pouch comprising:

• sidewalls that define a mouth;
• a first elongate closure member disposed proximate to the mouth, the first elongate closure member including a series of spaced features being disposed along an entire length of the first elongate closure member, the series of spaced features being disposed on at least one of (i) an outer surface of the first elongate closure member and (ii) an inner surface of the first elongate closure member, the series of spaced features being spaced apart along the entire length of the first elongate closure member, with each feature of the series of spaced features being spaced a distance D1 from an adjacent feature of the series of spaced features, such that the distance D1 between each feature and the adjacent feature is the same along the entire length of the first elongate closure member;
• a second elongate closure member disposed proximate to the mouth, the second elongate closure member including a series of spaced features being disposed along an entire length of the second elongate closure member, the series of spaced features being disposed on at least one of (i) an outer surface of the second elongate closure member and (ii) an inner surface of the second elongate closure member, the series of spaced features being spaced apart along the entire length of the second elongate closure member, with each feature of the series of spaced features being spaced a distance D2 from an adjacent feature of the series of spaced features, such that the distance D2 between each feature and the adjacent feature is the same along the entire length of the second elongate closure member, the distance D1 being greater than the distance D2, and 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 close or to open the first and second elongate closure members, such that portions of the slider engage with (i) the series of spaced features on the first elongate closure member to produce a first feedback at a first frequency, and (ii) the series of spaced features on the second elongate closure member to produce a second feedback at a second frequency, as the slider is slid along the first and second elongate closure members,
• wherein the first feedback at the first frequency differs from the second feedback at the second frequency due to the distance D1 between each of the spaced features of the series on the first elongate closure member being greater than the distance D2 between each of the spaced features of the series on the second elongate closure member.
