  • a packaging container 1 which in the present case is designed as a soft plastic bag, consists of flexible walls 2, which can be made of plastic, paper or the like.
  • the web-like material forming the walls 2 is closed to the container 1 by welding or adhesive seams 3, 4, 5.
  • the welded or glued seams consist of a longitudinal seam 3, through which the sheet-like material of the walls 2 is first closed to form a tube, a lower transverse seam 5 for closing the bottom and an upper transverse seam 4 for closing the upper end.
  • a filling and / or emptying opening 6, generally designated 6, is provided in the upper transverse seam 5.
  • a valve device In one of the welded or glued seams 3, 4 or 5, i.e.
  • a valve device In the exemplary embodiment in the upper transverse seam 4, a valve device, generally designated 7, is arranged according to the invention, which is designed to be self-closing and which is kept closed by the pressure generated in the interior of the container 1 by the filled material.
  • FIGS. 2 to 4 illustrate the operation of the valve device in a schematic representation.
  • FIGS. 2 to 4 it is sectional views substantially along the line II-II of Figure 1, the same reference numerals have been used for the same parts, and further for the purpose of clarity, the wall thicknesses are shown greatly exaggerated.
  • valve device 7 consists of a tubular body 8 which contains the filling and / or emptying opening 6 or more precisely surrounds it.
  • the tubular body 8 is preferably made of the same material as the walls 2 of the packaging container 1, e.g. in particular from polyethylene, where a somewhat stiffer variant of this material can optionally be selected.
  • tubular body 8 in the upper transverse seam 4 is connected to the wall material of the packaging container 1 by side weld seams 9 and 10.
  • the tubular body in its rest state shown in FIG. 2 has a strongly flattened diameter.
  • FIGS. 1 and 2 Before the function of the valve device is explained in more detail, reference is first made to FIGS. 1 and 2, since to fill the packaging container 1 according to FIGS. 3 and 4, first the packaging container according to FIGS and 2 must be brought into a state that enables filling.
  • the inlet opening 12 of the valve device formed by the tubular body 8 is arranged in a closed prechamber 14 which is closed to the outside world by an additional weld or adhesive seam 16.
  • the pre-chamber 14 can be separated from the packaging container 1 along a perforation 18.
