Abstract
A discharge device for discharging a liquid content in a tube container in a droplet form, in which a tube main body; a tube head including an integrated discharge rod; a regulating unit provided in an assembly space of the tube head; and a valve unit are sequentially assembled, so that a uniform amount of the liquid content is discharged in the droplet form through a narrow passage and a wide passage, and then through the wide passage and a narrow passage when the liquid content is discharged in the droplet form in a process of discharging the liquid content through a discharge passage by a pressure applied by a user. Accordingly, an appropriate amount of the liquid content is smoothly used. Particularly, long-term use of the liquid content is ensured, and the uniform amount of the liquid content is accurately discharged in the droplet form.
