A pouch has an elongate closure mechanism adapted to provide vacuum retention within 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 a pair of sealing members that form an air tight seal separate from the interlocking members disposed between the first and second pairs of interlocking members. The closure members are connected with opposing panels of the pouch in a manner designed to provide differential opening and closing forces. The pouch may include a check valve and air evacuation channels to aid in evacuating air from the interior.

An airtight resealable closure mechanism having an elongate profile extending between a first end and a second end, the profile comprising:a first closure element having a first interlocking member, a second interlocking member, and a first sealing member, each protruding from a first b
We claim: 1. An airtight resealable closure mechanism having an elongate profile extending between a first end and a second end, the profile comprising:a first closure element having a first interlocking member, a second interlocking member, and a first sealing member, each protruding from a first base member, wherein the first sealing member is disposed between the first and second interlocking members; anda second closure element having a third interlocking member, a fourth interlocking member, and a second sealing member, each protruding from a second base member, wherein the second sealing member forms a tapered channel and is disposed between the third and fourth interlocking members;wherein the first and second interlocking members are resealably interlocked with the third and fourth interlocking members, respectively;wherein the first sealing member is wedged into the tapered channel of the second sealing member, whereby an airtight seal is formed; andwherein the first and second sealing members are spaced from each of the first, second, third, and fourth, interlocking members.
