Abstract
Methods and apparatus for filling a cavity with a liquid from a hypodermic needle through a port provide the port with a straight passage leading to the cavity either directly or through a laterally offset further passage. The needle is partially inserted into the straight passage of the port. The partially inserted needle is stopped by engagement inside the port short of the cavity while an overflow and gas escape path is provided through the straight passage along the outside of the stopped partially inserted needle.
