Abstract
An apparatus for admitting metered quantities of a pressurized liquid into successive containers, such as cans or bottles, has a housing which stores a supply of pressurized liquid and carries one or more combined container sealing and centering units. Each such unit has a vertically reciprocable at least partially elastomeric tubular member movable between a lower end position and an upper end position. The external surface of the annular upper end portion of the tubular member sealingly engages a cylindrical internal surface which surrounds the outlet of the housing when the tubular member assumes its lower end position, and an end face of the annular lower end portion of the tubular member is then in sealing engagement with the open top of a container to be filled. The open lower end of a conduit for compressed gas is located at the upper end of the passage within the tubular member to ensure that the upper end portion of the tubular member can be expanded into sealing engagement with the internal surface. The tubular member and the housing define an annular clearance in the upper end position of the tubular member so that the latter can be readily cleaned from the inside and from the outside.
