Insert for dropper with locking system in the stopper and anti-squirt system, wherein an insert (10) has an eccentric bore (11) and includes on the outer surface thereof a neck (12) with a circumferential projection (13) with a sloping end (14) around its free edge. The insert (10) is locked at the level of its neck (12) in the liquid inlet (4) of the dropper (2), closing the stopper (1), leaving free passage only through the eccentric bore (11). After the previously locked dropper (2) is inserted together with the insert (10) into a bottle (3), the latter is turned upside down and pressed during use, causing the liquid to flow through the bore (11) which, because it is eccentrically arranged, causes the volume of liquid to squirt against the wall of the chamber (6) in the stopper (1), forming a barrier that retains the volume of liquid therein. If pressure continues to be applied to the bottle (3), a smaller amount of liquid escapes from the chamber (6) through the aligned flow channel (7) and outlet (8) in the spout (9). The liquid thus always flows out in the form of drops, and an anti-squirt system is obtained which prevents uncontrolled metering. |
