Abstract: A method for pressing a sealing compound onto the inside of a lid for containers is described. An annular structure consisting of plasticized sealing compound is located on the lid base and is pressed flat by means of an annular press punch onto the lid base and onto the lid wall adjacent to the lid base. The annular press punch is pressed between an inner molded part arranged radially to the inside of the press punch, and an annular outer molded part arranged radially to the outside of the press punch and forming an annular gap to the lid base, and is pressed toward the lid base onto the annular structure. The plasticized sealing compound is pressed into the gap and radially to the outside through the gap onto the lid base and onto the lid wall adjacent to the lid base. A corresponding device is also described.
