Abstract

See full text

The present invention is a container for storing fine particles in a sealed packaging, wherein air in the container can be evacuated through compression or vacuum without removing the fine particles. The container comprises a main body enclosing a pouch, terminating in a principal opening, a sealing mechanism attached to the pouch for sealing the pouch, at least one exit port extending through the wall of the pouch, and a porosity mechanism adjacent the exit port, wherein the porosity mechanism permits air to exit through the exit port, but prevents the fine particles from escaping through the exit port.
