Abstract (en)
A screw cap opening/ closure assistance mechanism (10) assists in opening and closure of a screw cap (20) in a screw cap mechanism. The screw cap opening/closure assistance mechanism includes a coupling part (13) provided on the screw cap (20) and an opening/ closure assistance part (14) connected to the coupling part (13). One end of the coupling part is adapted to be rotated in unison with the screw cap (20). This opening/ closure assistance part is positioned in proximity to an outer surface of the screw cap (20) when the screw cap opening/ closure assistance mechanism has not been used or when it is not in use. For opening/ closure, the screw cap opening/ closure assistance part is moved away from the screw cap (20) so as to form a large diameter moving part rotatable in unison with the screw cap (20), An arrangement is so made that the force of rotation needed for the opening/closure operation for the screw cap (20) may be smaller.
