Device to fill liquid to pasty foodstuffs into prefabricated individual containers which form a sealing edge, - having support elements which are continuously guided through the device by means of a drive and have receiving openings for the individual containers, - having work stations in whose operative region the support elements enter on their continuous circulation through the device, - having at least one work station designed as a sealing device which fixes a sealing film on the sealing edge of each individual cup by means of a sealing tool, wherein each sealing tool is a sealing head vertically movable up and down by means of an actuation rod, - having a web-like sealing film, spanning the support elements in their width measured transverse to the feed direction, said sealing film being guided between the sealing edge of the individual containers and the sealing head, - having a deflection device which is upstream of the sealing device in the feed direction and transfers the sealing film into an alignment suitably sealed and parallel to the feed direction, - having a gas injection device upstream of the sealing device in the feed direction which fills an unfilled head region of the individual containers with an oxygen-reduced to oxygen-free gas, - having a spacing gap between the sealing film and the support elements, characterised in that - at least one sealing film hold-down device is arranged in the region of the sealing device, - the sealing film hold-down device is aligned parallel to the feed direction, - the spacing gap between the sealing film and the support elements is adaptable by means of the vertically-adjustable sealing film hold-down device and the sealing film hold-down device thus holds the sealing film between it and a support element at a defined distance to the support element. - having support elements which are continuously guided through the device by means of a drive and have receiving openings for the individual containers, - having work stations in whose operative region the support elements enter on their continuous circulation through the device, - having at least one work station designed as a sealing device which fixes a sealing film on the sealing edge of each individual cup by means of a sealing tool, wherein each sealing tool is a sealing head vertically movable up and down by means of an actuation rod, - having a web-like sealing film, spanning the support elements in their width measured transverse to the feed direction, said sealing film being guided between the sealing edge of the individual containers and the sealing head, - having a deflection device which is upstream of the sealing device in the feed direction and transfers the sealing film into an alignment suitably sealed and parallel to the feed direction, - having a gas injection device upstream of the sealing device in the feed direction which fills an unfilled head region of the individual containers with an oxygen-reduced to oxygen-free gas, - having a spacing gap between the sealing film and the support elements, - at least one sealing film hold-down device is arranged in the region of the sealing device, - the sealing film hold-down device is aligned parallel to the feed direction, - the spacing gap between the sealing film and the support elements is adaptable by means of the vertically-adjustable sealing film hold-down device and the sealing film hold-down device thus holds the sealing film between it and a support element at a defined distance to the support element.
