A pouch has an airtight 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 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.
We claim: 1. An airtight resealable closure mechanism having an elongate substantially constant 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
We claim: 1. An airtight resealable closure mechanism having an elongate substantially constant 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; and a 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 generally V-shaped tapered channel and is disposed between the third and fourth interlocking members; wherein the first interlocking member is resealably interlocked with the third interlocking member and the second interlocking member is resealably interlocked with the fourth interlocking member; wherein each of the first and second interlocking members comprises a pair of arms forming a channel-shaped female interlocking member, and wherein each of the third and fourth interlocking members comprises an arrow-shaped male interlocking member; wherein the first sealing member is wedged into the generally V-shaped tapered channel of the second sealing member, whereby an airtight seal is formed; and wherein the first and second sealing members are spaced from each of the first, second, third, and fourth, interlocking members. 2. The closure mechanism of claim 1, wherein the first sealing member comprises a first rib disposed between a second rib and a third rib, wherein each of the first, second, and third ribs is T-shaped, and wherein the first rib is wedged within the generally V-shaped tapered channel. 3. The closure mechanism of claim 2, wherein the second sealing member comprises a first wall spaced from a second wall defining the generally V-shaped tapered channel therebetween, wherein the first wall is disposed between the first rib and the second rib, and the second wall is disposed between the first rib and the third rib. 4. The closure mechanism of claim 3, wherein the first wall is wedged between the first and second ribs and the second wall is wedged between the first and third ribs. 5. The closure mechanism of claim 1, wherein the first closure element is continuously connected to a first sidewall between the first interlocking member and the second interlocking member, and wherein the second closure element is continuously connected to a second sidewall between the third interlocking member and the second sealing member and not connected to the second sidewall proximate the fourth interlocking member, and one or more of the first, second, third, and fourth interlocking members includes a textured portion along the length of each member to provide tactile and/or audible sensations when the closure mechanism is occluded.
