ABSTRACT:
The bag for friable material comprises a bottom surface panel for defining the bottom of the bag with respect to the vertical sides and the top portions of the bag when the bag is filled. The bag includes a discharge opening in the bottom surface panel which is defined by surrounding portions of the bottom surface panel. A foldable discharge spout is connected to the surrounding portions of the bottom surface panel for being maintained within the discharge opening when the beg is filled. A closure flap covers the discharge opening and the spout for being pulled open when the bag is filled. When the flap is pulled open, the spout unfolds under the weight of the contents and permits those contents to discharge. A pull strap is connected to the closure flap and has a length sufficient for portions to extend outwardly from one of the vertical sides of the bag. The bag includes means on the bottom surface panel and adjacent the one vertical side for supporting portions of the strap adjacent the vertical side when the bag is filled. As a result, when the strap is pulled outwardly from the vertical side, it in turn pulls the closure flap from the opening, thereby allowing the spout to unfold and the contents to discharge. This permits the bag to be opened from the side, rather than from underneath.
