Abstract:
1. A method of maintaining a bag in an open mouth condition for filling with material, the bag having an inner circumference and a filling extent which extends from a mouth opening to a closed end thereof, the method comprising: inserting an elongated object having resilient characteristics over at least a length portion thereof into the mouth opening of the bag; flexing the elongated object lengthwise to create a bend over said at least a length portion of the elongated object, at least a portion of said at least a length portion of the elongated object being located in a central section of the elongated object; guiding a circumferential portion of said inner circumference of the bag to conformably follow a path defined by the elongated object from a one end of said elongated object to an opposite end thereof positioning said elongated object in the bag such that only a minor portion of said filling extent overlaps said elongated object in a width direction thereof and a major portion of said filling extent of the bag remains free of contact with the elongated object; and releasing flexing tension on the elongated object whereby the elongated object is retained in a position adjacent to the mouth opening of the bag.
