    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.

    Abstract: A one-way air outlet channel is disposed inside a vacuum compression bag. The one-way air outlet channel includes an air inlet opening, a horizontal air channel, inclined air channel and vertical air channel and an air outlet opening in communication with one another in sequence. One end of the horizontal air channel is the air inlet opening in communication with a space inside the bag body, and the other end of the horizontal air channel is in communication with the inclined air channel. A bottom end of the vertical air channel is in communication with the air outlet opening, and a top end is in communication with the inclined air channel, such that at least two corner points are formed, at a location where the horizontal air channel connects the inclined air channel and at a location where the inclined air channel connects the vertical air channel.
