Abstract
A container for drop-by-drop dispensing of a fluid substance comprises a bottle having a detachable stopper mounted movably on the neck of the bottle so that, in a stoppering position, discharge ports of the stopper are closed off by the neck of the bottle and in a remote position the discharge ports are open. A flexible discharge end fitting which may be squeezed to actuate dispensing of the fluid substance is a snap fit on the relatively harder stopper. The discharge end fitting is limited in its travel towards the remote position along the neck so that the two part stopper/discharge fitting unit is captive on the neck.
