Abstract
A process for the foaming of the headspace of containers filled with carbonated beverages, wherein, after the filling of the beverages into the containers, the containers are transferred to a foaming area, in which an electromagnetic beam, preferably a laser beam, is irradiated in a controlled way into the headspace of the container which is not filled with the beverage, whereby, due to the resultant foaming, the gas volume in the headspace is displaced from it, and the containers are subsequently sealed, as well as to a device for carrying out the process.
