Abstract

The invention relates to a method for producing a tamper-proof closure for a plastic container for holding food, comprising the following steps: placing the lid (5, 5') onto the filled container (1, 1') so that the lid locks with the container (1, 1'), wherein a second lid-side web (7, 7') overlaps a first container-side web (2, 2'), laying the container (1, 1') with a bottom side of the first web (2, 2') onto an annular anvil, and welding the first web (2, 2') to the second web (7, 7') by means of ultrasound in an ultrasonic welding apparatus.
