Abstract
There is provided a method for sealing a filling orifice formed on a wall of a container in a leak-proof manner using a stopper arrangement comprising a tubular member with a flange having an upper face, and a lower face for covering the orifice, and a mandrel with a stem which is housed inside the tubular member, the force necessary for rupturing the stem being greater than the force resulting from the entry and advancement of a head of the mandrel inside the tubular member, comprising introducing the stopper arrangement into the orifice, bringing the nosepiece of the riveting tool into abutment with the upper face of the flange, actuating the riveting tool so as to exert a tensile force on the stem and bring about expansion of the tubular member against the wall of the orifice and rupturing the stem of the stopper arrangement.
