Abstract:
A method of making a container for holding fine particles comprising the steps of:selecting a sheet of material of predetermined area, the sheet having an edge about its perimeter; installing an exit port through the sheet; securing a porosity mechanism over the exit port; folding the sheet onto itself to form two major opposing surfaces; sealing the opposing surfaces along all but a portion of the edge to form a pouch, the unsealed edge forming a principal opening; introducing a fill material into the pouch; securing a resealable sealing mechanism to both major surfaces adjacent the principal opening, the resealable sealing mechanism sealing the pouch, unless unsealed, whereby air is entrapped within the sealed pouch; and compressing the pouch to expel entrapped air through the exit port to form an aspirated container.
