摘要

The dropper has cylindrical sides that fit inside the bottle neck. The top of the dropper is flanged (8) so that it can rest on top of the bottle without falling inside it. There is a base (6) which closes off the cylinder. The dropper is traversed by two tubes (9, 10). One tube allows a small quantity of air into the bottle. The other allows a small quantity of liq. out. Both tubes are flush with the flange at the top. One tube (9) protrudes into the bottle beyond the base (6). The bottle is fitted with a stopper (5) which screws onto the bottle neck.
