Abstract
A reclosable pouch includes a first side wall and a second side wall joined together to form a bag. The pouch has an open top for receiving and removing items to be stored, such as food or other material. The pouch further includes at least one closure mechanism near the open top of the bag which provides for a reclosable bag. Each closure mechanism comprises a male closure element and a female closure element aligned on the opposing first and second side walls, respectively. The male closure element is asymmetrically deformed in a plurality of intermittent section. Preferably, the closure mechanism is a double zipper with at least one male section including one hook extending from an end thereof to engage the female closure element. The closure mechanism provides a clicking feel and/or sound when the pouch is closed. The closure mechanism is substantially leak-proof when closed.
