ABSTRACT:
A counterpressure type container filling apparatus typically includes a housing defining an annular liquid feed passageway therein, a valve for opening and closing the liquid feed passageway, a holding member externally fitted to the housing in a slidable manner and provided with a sealing element for sealing a container to be filled, and a gas pipe for introducing gas into the container or for allowing gas to escape from the container. The gas pipe is detachably mounted to the holding member and is projectable into the container in cooperation with the holding member. The improvements offered by the present invention act to apply an appropriate sealing pressure to the container, to facilitate the replacement of the holding member and the gas pipe, and to prevent the application of an excessively large pressure to the side wall of the container. These improvements reside in that the holding member is provided with an engaging member on its outer circumferential surface, which engaging member is detachably engaged with a central engaging portion of an arm member. The arm member has one end pivotably mounted to a fixed member and another end limited from descending. Further, the arm member is biased downwardly by a resilient member.
