Abstract: A method for producing a packaging container having a pressure relief valve that is tightly secured to the inside of the packaging container and closes off an opening in the wall of the packaging container. To seal off the pressure relief valve, a fluid sealant is introduced into the valve, after the valve has been secured to the packaging container. To this end, an opening is punched by a hollow needle into the wall of the packaging container in the area coinciding with the pressure relief valve, and through the hollow needle a droplet of sealant is deposited in the peripheral zone of a membrane of the pressure relief valve. By capillary action, the sealant enters into the gap between a carrier part and the membrane of the valve and becomes distributed over this area.
