A slider actuated closure mechanism includes internal projections that extend from interior sides of the closure elements and retention members that extend from exterior sides of the closure elements. A slider is disposed over the first and second closure elements and includes first and second sidewalls each including a shoulder inwardly extending from a distal end thereof. When the slider is disposed over the first and second closure elements, the first sidewall and the first closure element are minimally horizontally separated by a distance d1, the second sidewall and the second closure element are minimally horizontally separated by a distance d2, and the internal projections are horizontally separated by a distance d3. The sum of the distances d1, d2, and d3 equals a total non-zero distance, dt, that is less than a length that each of the shoulders inwardly extends from the respective first and second sidewalls.
