Dropper cap characterized in that it is formed of a piece of preferably moldable material in order to obtain elasticity and consists of a hollow central stem opened at the bottom where the adaptation of a glass dropper tube is provided, this mouth having an external shape hemispherical in whose upper part immediately below the circular abutment platform has been practiced a peripheral channel that will be coincident with a projection of analogous form on the inside of the neck of the bottle to which the cap is destined to exert the suction by pressure on the upper area of the same zone of cylindrical shape crowned by a hemisphere of the same radius being its coupling to the bottle by simple pressure fixed in its closed position by means of the slot that we have described.
