A recloseable pouch defining an interior including a first wall, a second wall opposing and partially sealed to the first wall to form an opening, and a closure mechanism for selectively sealing the opening. The closure mechanism includes a female closure element having first and second spaced legs
A recloseable pouch defining an interior including a first wall, a second wall opposing and partially sealed to the first wall to form an opening, and a closure mechanism for selectively sealing the opening. The closure mechanism includes a female closure element having first and second spaced legs extending from the first wall that are substantially symmetric about a longitudinal centerline and defining female sealing surfaces. The closure mechanism also includes a male closure element including a proximal base portion extending from the second wall, a neck portion forming male sealing surfaces to engage the female sealing surfaces, and a distal head portion. The male closure element has a plurality of intermittent deformed portions so that upon inserting the proximal base portion into the female closure element, the female closure element deflects and, in turn, fluid is allowed to flow past the closure mechanism via the adjacent intermittent portions.
