Abstract (en)
[origin: WO8702009A1] A container for use with a tamper evident closure (18) has a neck (10) with first (11) and second (13) opposed thread portions spaced apart and adapted to respectively engage the cap (19) and interconnected ring (20) of the closure when it is initially installed on the container. When the closure is first rotated to remove the cap the ring is caused to rotate therewith and because the thread portions are opposed the cap and ring move in opposite axial directions, that is, in opposite directions along the axis of rotation. This axial movement causes the interconnection to fracture and subsequent tightening of the cap leaves a readily discernible gap between the cap and ring. A stepped ledge (14) between the two thread portions prevents removal of the ring after initial installation.
