To evacuate the air from a container would bring about a vacuum of some depth. Plastic containers would tend to collapse inward from the greater air pressure on the outside wall of the container. Glass would probably be more effective for this. It would require a fairly adequate seal to prevent atmospheric pressure from reintroducing air into the container.

I use the Evac containers for some of my chems. They are more prone to leakage (in my experience) along the ribs that flex. The dirt consideration isn't too big a problem. Fairly easy to rinse them off with running water.
