Abstract
A bag construction filled with dispersible material. The bag construction has first and second panel sections, first and second side gusset sections and a bottom gusset panel section. The various panel sections are fastened together to form a generally rectangle shape with a flat bottom. The bottom gusset panel section has one or more distribution apertures in it. A removable panel layer is provided for covering the one or more apertures. When the removable panel layer is removed, the bag can be held so that the dispersible material disperses through the apertures as appropriate.
