ABSTRACT:
A closure-container package is illustrated in which the closure is pressed-on to the container neck and threaded off the container neck. Either the container neck or the closure has a helical thread which engages axially extending ribs on the other of the container neck or closure to form indentations in the ribs which act as threads, teeth or a track for unthreading. A continuous or rotary seal is used between the container neck and the closure which does not require a sealing force from the threaded connection.
