Abstract
A bulk solids container can include a bag to hold the bulk solid, a rigid base to support the bag, and rods extending up from the base to the top of the bag. The rods provide vertical structural integrity to the sides of the bag. The base can include a sloped upper surface sloping down towards a discharge opening located near the center of the base and aeration openings that inhibit or prevent the bulk solids from clogging the discharge opening during removal of the bulk solids from the bag. When the bag is empty, the bag and the rods can be collapsed and fit on top of the upper surface of the base. The container can be transported back to a fill facility to be reused.
