Abstract: Disclosed are systems and methods for making and using a valving system that can be used with containers. In some embodiments, a valving system for a silicone bag can include an air sieve coupled to a sidewall of the silicone bag. The sidewall of the silicone bag can include a perforation to allow outflow air out of the bag. The air sieve can include a sealing seat that is configured to cooperate with the sidewall to provide a seal that prevents external air from entering the container. Using a vacuum inducing device, air can be evacuated from the container by inducing air to flow through channels in the air sieve and out of the perforation in the sidewall.
