Airless type mixing container for two kinds of contents capable of discharging all contents

An airless type mixing container for two kinds of contents, in which the two kinds of contents are separately stored and are able to be used by mixing, the airless type mixing container being capable of discharging all the contents and comprising:

• a main container having an opening part formed with a screw thread having an outer circumferential surface thereof on which a shoulder of a contents discharge pumping member is assembled, the opening part having a narrowed upper part thereof in a through-type tube shape, and having a finishing cap assembled therein and provided with an air inlet hole at a lower part thereof where a piston is assembled, the main container accommodating one of the two kinds of contents;
• an auxiliary container mounting member being positioned inside of a content receiving part through the opening part at the upper part of the main container so that a flange at an upper part thereof is locked by an upper edge part of the opening part, and having a locking annular rim on which a locking annular rim formed on an outer surface of a body of an auxiliary container is locked along an inner circumferential surface of a lower part of the auxiliary container mounting member;
• the auxiliary container inserted into the lower part of the auxiliary container mounting member and closely assembled by an airtight ring provided on an outer circumferential surface of a lower assembly part, having the body formed by being concentrical with the inner circumferential surface of the auxiliary container mounting member on an upper part of the assembly part and formed with a discharge path configured to allow the two kinds of contents to flow down, and having the locking annular rim locked by the locking annular rim of the auxiliary container mounting member at an upper part of an outer circumferential surface of the body, and
• the contents discharge pumping member having a fixing member of a discharge pump that comprises a push button so as to enable pumping operation, the fixing member draping over the flange of the auxiliary container mounting member positioned at the opening part of the main container, and comprising the shoulder that enables the fixing member to be assembled and fixed to the opening part of the main container.
