CONTAINER FOR STORING FINE PARTICLES

摘要

The present invention is a container (10) for storing fine particles (12) such as bakery flour in a sealed packaging, wherein air in the container such as entrapped during filling can be expelled through compression without loss of the fine particles. The container comprises a main body (11) enclosing a pouch (14), terminating in a principal opening (16), fabricated from an imperforate flexible material such as clear plastic film, a sealing mechanism (18) attached to the pouch for sealing the pouch, and a multiplicity of microscopic pores (42) extending through the flexible material having a dimension ranging from 10 to 150 mu m sufficient to permit air to exit through the exit port, but to prevent the fine particles from escaping through the pores. An anti-slip feature is supplied by an exterior coating (50) onto a pouch.
