<p>The bottle is of the type which has an external, annular flange around the outlet of the neck to be stoppered. The stopper has an elastically deformable, cylindrical skirt which drops over the neck. The skirt has integral, springy catches which are cranked inwards normally to engage the underside of the neck flange. This prevents removal of the stopper until pressure is applied radially inwards on the bottom of the skirt to spring the catches outwards to clear the flange.</p> |
