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.

A resealable pouch comprising: a front panel connected with a back panel along a peripheral edge to define a sealable interior space therebetween;an opening defined between the front and back panels along a top edge;a first elongate closure profile extending along the front panel proximate to the
1. A resealable pouch comprising: a front panel connected with a back panel along a peripheral edge to define a sealable interior space therebetween;an opening defined between the front and back panels along a top edge;a first elongate closure profile extending along the front panel proximate to the opening, the first elongate closure profile including (i) a base member, (ii) a first interlocking member extending from the base member, (iii) a second interlocking member extending from the base member, and (iv) a first sealing member spaced between the first and second interlocking members, the first sealing member comprising (a) a first sealing wall extending from the base member and comprising a tapered tip, and (b) a second sealing wall extending from the base member and comprising a tapered tip, the first sealing wall being spaced from the second sealing wall to define a tapered channel therebetween, wherein each of the first and second sealing walls comprises a base adjacent to the base member of the first elongate closure profile, such that the tapered tip of each of the first and second sealing walls is narrower than their respective base; anda second elongate closure profile extending along the back panel proximate to the opening, the second elongate closure profile being releasably interlockable with the first closure profile to seal and to unseal the opening, the second closure profile including (i) a base member, (ii) a first interlocking member extending from the base member, (iii) a second interlocking member extending from the base member, and (iv) a second sealing member spaced between the first and second interlocking members, the second sealing member comprising (a) a first sealing rib extending from the base member, (b) a second sealing rib extending from the base member, and (c) a third sealing rib extending from the base member, the first sealing rib being disposed between the second sealing rib and the third sealing rib, and the first sealing rib being wedged between the first sealing wall and the second sealing wall within the tapered channel,wherein the first sealing member is sealingly engageable with the second sealing member, and the first and second interlocking members of the first elongate closure profile are interlockable with the first and second interlocking members of the second elongate closure profile, respectively,wherein the first elongate closure profile is continuously connected to the back panel between the first and second interlocking members of the first closure profile, andwherein the second elongate closure profile is continuously connected to the front panel between the first interlocking member of the second closure profile and the sealing member of the second closure profile, and not connected to the front panel proximate to the second interlocking member of the second closure profile. 2. The resealable pouch of claim 1, wherein the second interlocking member of the second elongate closure profile is disposed on an interior side of the sealing member of the second elongate closure profile. 3. The resealable pouch of claim 1, wherein the first closure profile is connected to the front panel by a substantially continuous first connecting layer disposed therebetween, and the second closure profile is connected to the back panel by a substantially continuous second connecting layer disposed therebetween. 4. The resealable pouch of claim 3, wherein at least one of the first and second connecting layers comprises a thermoplastic weld material. 5. The resealable pouch of claim 1, further comprising a grip ridge disposed on a portion of at least one of the front and back panels, the grip ridge being disposed on an exterior side of the closure profiles. 6. The resealable pouch of claim 1, wherein the first sealing wall is wedged between the first sealing rib and the second sealing rib, and the second sealing wall is wedged between the first sealing rib and the third sealing rib. 7. The resealable pouch of claim 6, wherein each of the first, second, and third sealing ribs has a bulbous head, and each of the first and second sealing walls has tapered sides. 8. The resealable pouch of claim 6, wherein one of the first and second interlocking members of the first elongate closure profile is an elongate arrow-shaped interlocking profile and the other of the first and second interlocking members of the first elongate closure profile is an elongate channel-shaped interlocking profile, and the first and second interlocking members of the second elongate closure profile are complementary respective elongate arrow-shaped male and elongate channel-shaped female interlocking profiles. 9. The resealable pouch of claim 1, further comprising a vacuum check valve disposed in at least one of the front and back panels through which air may be evacuated from the interior space. 10. The resealable pouch of claim 1, further comprising air flow channels defined along at least one of the front and back panels for allowing passage of air during evacuation of the pouch. 11. The resealable pouch of claim 1, wherein the first and second interlocking members of the first elongate closure profile and the first and second sealing walls each extend substantially the same distance from the base member of the first elongate closure profile. 12. The resealable pouch of claim 1, wherein the first and second sealing walls are spaced from the base member of the second elongate closure profile and the first, second, and third sealing ribs are spaced from the base member of the first elongate closure profile when the first and second interlocking members of the first elongate closure profile are interlocked with the first and second interlocking members of the second elongate closure profile.
