<p>The present invention is a container (10) for storing fine particles (12) in a sealed packaging, wherein air (34) in the container can be evacuated through compression or vacuum without removing the fine particles. The container comprises a main body enclosing a pouch (14), terminating in a principal opening (16), a sealing mechanism (18) attached to the pouch for sealing the pouch, at least one exit port (24) extending through the wall of the pouch, and a porosity mechanism (26) 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.</p> |
