Abstract (en)
[origin: EP0498047A1] A cross or block bottom valve bag is described with a filling valve which is inserted in the region of a valve-forming corner tuck (4), and which has a valve tube (8) that can be pushed onto the filling stub (16) of a valve bag filling device (17) and projects into the bag interior. A partition of filter material is inserted between the underside of the valve tube (8) facing the corner tuck (4) and the upper side of the corner tuck (4), is normally held in a plane parallel to the valve tube (8) and corner tuck (4), and is deformable into a functional position forming an air discharge window (15) by the raised air pressure prevailing in the bag interior during filling of filling material via the filling stub (16) of the filling device (17). <IMAGE>
