Provided is a manually operated dropper for sucking in and squeezing out a predetermined amount of liquid content when an elastic button thereof is pressed. The manually operated dropper of the present invention includes a housing which forms an outer appearance of the dropper and contains the contents therein, a housing cap for sealing an internal space of the housing from the outside, a tubular body which sucks in contents from the housing and is coupled to an elastic button, an elastic button seal coupled to a top of the tubular body and joined to the housing cap, and a closure which covers an outer surface of the elastic button in such a manner that both sides of the elastic button are exposed so as to protect the button from forces applied from an external source and suck in contents at constant rate. The closure is coupled to the housing cap. |
