Container for discharging liquid contents

A container for discharging liquid contents, comprising:

• an inner container in which liquid contents are accommodated;
• an outer container surrounding the outside of the inner container;
• a sealing frame which blocks an open side of the outer container, is coupled with the inner container, and is provided with an air inlet hole;
• an air inlet valve which is installed in the sealing frame and opens and closes the air inlet hole in response to changes in the pressure inside the outer container;
• a shoulder which is coupled to one side of the outer container and surrounds the sealing frame, and is provided with a discharge passage formed therein;
• a nozzle which is coupled to the shoulder and is provided with a discharge port formed therein;
• and
• a discharge valve which is installed on the shoulder and opens and closes the discharge passage by means of the discharge pressure of the liquid contents, wherein the shoulder is provided with a first tightly-contacting protrusion on the lower side, and a second tightly-contacting protrusion that is spaced apart from the outside of the first tightly-contacting protrusion at a predetermined interval, said first and second tightly-contacting protrusions being tightly contact with the both sides of a hard coupling portion of the inner container and the sealing frame, such that the inner container and the sealing frame are not spaced from each other.
