摘要

Scholarship to volume with assembly of valve door and method for dispensing material from a stock exchange for volume. Bag for volume (10) includes a housing (15), and a set of valve door (16), and is configured to retain a material (98).The set of valves door (16) includes a door (20) which runs to prevent selectively and to facilitate variation of rate of material distribution (98) of the stock exchange volume (10). And, more particularly, through an opening (13) defined by the casing (15) of the stock exchange volume (100.The set of valves door (16) has a configuration which, during movement of the door (20) to restrict the distribution of material (98) through the opening (13) in the housing (15), prevents the door (20) steer clear of other parts of the bag volume (10) such as, for example, parts of the inv u00f3lucro (15) which defines the opening. Methods are also provided.
