A closure mechanism for a pouch includes a first interlocking closure element and a second interlocking closure element. A first closure profile is disposed on an interior side of the first interlocking closure element. A flange extends from the first closure profile and has a first aperture disposed therethrough. A resilient valve flap covers the first aperture and is attached to an exterior side of the flange. The resilient valve flap includes a sealing member and an at least partially elastomeric latch attached between a distal end of the sealing member and the exterior side of the flange. A channel is defined between the resilient valve flap and the flange that extends from the first aperture to an edge of the resilient flap. The resilient valve flap is biased to form a releasable airtight seal against the exterior side of the flange across the channel.
