Abstract: A storage container apparatus is provided for storing air sensitive materials under a vacuum. The apparatus includes having a cylindrical container body opened at its upper end and a cap apparatus with an integral air pump to evacuate air from the container body to create a vacuum. The cap apparatus comprises an inner cap with a one-way air valve and an outer cap. The outer cap is slidably nested over the inner cap and confines a central air chamber which fills with air from the container body through the one-way air valve when pulled upwardly in a reciprocating motion. In the down stroke the air is evacuated from the air chamber through vents. The outer cap may include locking mechanism and vacuum level indicator. The outer cap may include an activated carbon cloth insert that suppresses odors from the material stored in the container.
