Container for discharging contents by a fixed amount including a dropper and pressurizing pump

A container for discharging contents thereof, the container comprising:

• a body for accommodating the contents therein;
• and
• a dropper having a first cap, detachably coupled to a top of the body, and configured to suck and discharge the contents accommodated within the body, the dropper comprising:
• a pipette coupled to an inside of the first cap to allow at least a portion of the pipette to be accommodated in the body to suck the contents of the body;
• and
• button parts comprising:
• a pressurizing part for changing an internal pressure of the pipette by a pressurization to discharge the contents sucked into the pipette;
• an ascending and descending part ascended together with the pressurizing part according to a detachment of the dropper to allow the pressurizing part to protrude outward from the first cap;
• and
• an elastic part disposed between the pressurizing part and the ascending and descending part, the elastic part configured to:
• compressedly deform when the pressurizing part is pressurized, and
• decompress by an elastic force when the pressurization is released,
• wherein the button parts are configured to be ascended by the elastic part to maintain a first separation distance between an underside of the pressurizing part and an underside of the ascending and descending part,
• wherein an upper end portion of the ascending and descending part is inserted into the pressurizing part, the ascending and descending part has a first locking protrusion protruding from an outer peripheral surface of top end thereof, and the pressurizing part has a second locking protrusion protruding inward from an inner peripheral surface thereof, and
• wherein when the pressurization against the pressurizing part is released, the first locking protrusion is locked onto the second locking protrusion, preventing the pressurizing part from escaping from the ascending and descending part.

• wherein the ascending and descending part has a support peripheral portion protruding outward from an outer peripheral surface of a lower end thereof, and the elastic part is provided to a form of a bellows type member and seated onto top of the support peripheral portion to surround the outer peripheral surface of the ascending and descending part, and
• wherein the pressurizing part has an extending portion extending from a bottom end periphery thereof to have a larger inner diameter than an inner diameter of the top end periphery thereof, and an upper end periphery of the elastic part is accommodated in a separation space formed between an inner peripheral surface of the extending portion and the outer peripheral surface of the ascending and descending part.
