Abstract (en)
[origin: WO8810221A1] A flexible bag (4) filled with the product (5) is accommodated in a rigid container (1). The flexible bag (4) is welded to the valve unit A. The container (1) is hermetically sealed by an annular membrane (17) press-filled in the container neck (19) and a double annular rib (18) press-filled in the annular groove (20) and by the weld (23) of the closure cap (22). The product is forced through the bore (11) in the valve disk (7) into the container when the valve piston is pressed into the bag (4) and by compressed air. The valve unit then closes the bag (4) and the washer (12), which functions as a non-return valve, seals the container (1) and prevents loss of pressure. When the valve unit is opened, the pressure in the container compresses the bag (4) so that the product can be dispensed through the nozzle (14).
