Abstract
Improvements in the construction of plastic bags or similar material equipped with a valve, characterized by being arranged in the vicinity of the edges of the walls of the bag, at least one organ capable of forming a valve for filling the bag, extending the longitudinal axis thereof substantially in the direction of said edges, said valve member having a closed-contour cross-section and being inserted in said edges between the walls of the bag to be joined, and welded to said walls along at least a section of said edges, opening at the exterior of the bag at least one end of said welded valve.
