A container for discharging contents, comprising: a container body in which contents are accommodated; and a dropper portion detachably coupled to an upper portion of the container body and configured to suction and discharge the contents in the container body, wherein the dropper portion comprises: an inner cap detachably coupled to the upper portion of the container body; a pipette portion coupled to the inner cap to communicate with an inside of the inner cap and having at least part thereof accommodated in the container body to suction the contents; a button portion (240, 250) comprising: a pressing portion configured to discharge the contents suctioned into the pipette portion by pressing; and an elastic member which is formed under the pressing portion to be disposed inside the inner cap and provides an elastic force to the pressing portion, characterized in that, the elastic member is accommodated in an uncompressed state in the inner cap and integrally lifted with the pressing portion from the inside of the inner cap during separation of the dropper portion from the container body, and at least part of the pressing portion protrudes outward due to the lifting of the pressing portion, the dropper portion further comprises an outer cap that is coupled to surround the inner cap and rotates integrally with the button portion (240, 250), at least one lifting protrusion is formed on the button portion (240, 250), at least one guide groove, into which the at least one lifting protrusion is inserted, is formed to pass through the inner cap along an outer circumferential surface, and when the outer cap is rotated in a first direction or a second direction opposite to the first direction in order to separate or couple the dropper portion from or to the container body, the at least one lifting protrusion moves along the guide groove so that the button portion (240, 250) is lifted or lowered. a container body in which contents are accommodated;
