ABSTRACT A closure cap adapted to seal the neck of a container, the closure cap having a top portion and an annular skirt which extends from the periphery of the top portion, the skirt being provided internally with a skirt thread which is adapted to cooperate with an external neck thread on the neck of the container, the skirt also being provided internally with a radially extending resilient annular thread flange which is disposed immediately adjacent to and on the same helix as the skirt thread and is disposed on the side of the skirt thread facing the open end of the skirt, the thread flange, when undeformed, extending substantially radially inwardly of the skirt thread with a gap therebetween, the thread flange, when the closure cap is fully screwed onto the neck resiliently engaging the outer wall of the neck to effect centralisation and resist loosening of the closure cap, the thread flange being forced by the neck towards the skirt thread so as to reduce said gap.
