Abstract
A pouch has an airtight elongate closure mechanism adapted to provide a vacuum retention with an interior of the pouch over an extended period of time when sealed. The closure mechanism includes a first pair of interlocking members that resealably mate together, a second pair of interlocking members that resealably mate together, and sealing members that form an air tight seal disposed between the first and second pairs of interlocking members. The closure elements may be connected with opposing sidewalls of the pouch in a manner designed to provide differential opening and closing forces. The pouch may also include a check valve and air evacuation channels to aid in evacuating air from the interior.
