[0038] The main container 10 is a through type, has a narrowed and stepped upper part thereof, and is provided with an opening part 11 formed with a screw thread having an outer circumferential surface on which a shoulder 42 of a content discharge pumping member 40 is assembled.

[0039] In a lower part of the main container where the piston 50 is assembled, a finishing cap 12 provided with an air inlet hole 13 is assembled and formed, and the content receiving part 14 in which one of the two kinds of contents is accommodated is formed.

[0040] In the auxiliary container mounting member 20 which is positioned in the content receiving part 14 of the main container 10, an upper flange 21 is locked on an upper edge part of the opening part 11 at an upper part of the main container 10, and a locking annular rim 22, in which a locking annular rim 32 formed on an outer surface of a body 31 of the auxiliary container 30 is locked, is formed along a lower inner circumferential surface of the auxiliary container mounting member.

[0041] The auxiliary container 30 mounted to the auxiliary container mounting member 20 is fitted into a lower part of the auxiliary container mounting member 20, and is airtightly assembled by an airtight ring 34 provided on an outer circumferential surface of the lower assembly part 33.

[0042] On an upper part of the assembly part 33, the body 31 having a discharge path 35 configured to allow the two kinds of contents to flow down into the content receiving part 14 of the main container 10 is formed concentrically with an inner circumferential surface of the auxiliary container mounting member 20.

[0043] At an upper part of an outer circumferential surface of the body 31, the locking annular rim 32 in which the locking annular rim 22 of the auxiliary container mounting member 20 is locked is formed.

[0044] In the contents discharge pumping member 40 mounted to the main container 10, a fixing member 43 of a discharge pump 41 that includes a push button 44 so as to enable pumping operation drapes over the flange 21 of the auxiliary container mounting member 20 which is positioned at the opening part 11 of the main container 10, and the discharge pump 41 in which the push button 44 is assembled to extend to a pumping piston rod 41a so as to enable the pumping operation includes a shoulder 42 to be assembled and fixed to the opening part 11 of the main container 10.

[0045] The auxiliary container mounting member 20 is configured to be narrowed while forming a step 23 at the upper end thereof so as to minimize assembly friction, and at the same time is configured to prevent the auxiliary container 30 from naturally being dropped due to its own weight, the auxiliary container being formed and assembled with a diameter that tapers downward the bottom thereof.

[0046] The discharge path 35 of the auxiliary container 30 is formed by cutting the body 31 downward from the upper part thereof and is configured to allow the two kinds of contents to flow down into the content receiving part 14 of the main container 10.

[0047] The piston 50 is provided with an airtight wing 52 being in close contact with an inner circumferential surface of the main container 10 and formed as an edge of the concave-type body 51, wherein the concave-type body 51 has a central part thereof formed in a concave shape and is in close contact with the assembly part 33 of the auxiliary container 30, the assembly part 33 being wrapped around by the concave-type body 51 so as to be able to discharge the mixed two kinds of contents without residual amount.

[0048] In the airless type mixing container for two kinds of contents capable of discharging all the contents configured as the above-described configuration, the piston 50 is mounted in the lower part of the main container 10.

[0049] The finishing cap 12 having the air inlet hole 13 is assembled at the lower part of the main container 10 in which the piston 50 is mounted.

[0050] When assembly of the main container 10 is completed, the auxiliary container mounting member 20 is mounted on the opening part 11.

[0051] Prior to assembling the auxiliary container mounting member 20 on the opening part 11, the auxiliary container 30 in which one of the two kinds of contents is filled is mounted at the lower part of the trunk 24 of the auxiliary container mounting member 20.

[0052] When mounting the auxiliary container 30 to the auxiliary container mounting member 20, the auxiliary container 30 is pushed from the bottom to the top in a state where the body 31 is made to face the top.

[0053] At this time, the locking annular rim 32 formed as the outer circumferential surface of the body 31 passes over the locking annular rim 22 formed as an inner circumferential surface of the trunk 24 of the auxiliary container mounting member 20, and when continually pushed up in the above-described state, the assembly part 33 including the airtight ring 34 is forcibly assembled by fitting into the lower part of the auxiliary container mounting member 20.

[0054] The auxiliary container mounting member 20 to which the auxiliary container 30 is assembled is mounted so as to be positioned in the content receiving part 14 through the opening part 11 of the main container 10.

[0055] As described above, the contents discharge pumping member 40 is mounted on the main container 10 in a state where the auxiliary container 30 is mounted on the main container 10 (see FIG. 1).

[0056] When two kinds of contents are to be filled and shipped in the airless type mixing container for two kinds of contents, capable of discharging all the contents, and being configured and assembled as described above, one of the two kinds of contents is filled first in the content receiving part 14 of the main container 10 as shown in FIG. 2.

[0057] Afterwards, the auxiliary container mounting member 20 in which the auxiliary container 30 is mounted is assembled through the opening part 11 of the main container 10 filled with the two kinds of contents.

[0058] The other of the two kinds of contents are filled in the auxiliary container 30 mounted on the main container 10 via the auxiliary container mounting member 20.

[0059] When filling of the two kinds of contents is completed, the shoulder 42 is fastened to the opening part 11 of the main container 10 to mount the contents discharge pumping member 40.

[0060] FIG. 3 is view showing a state in which the airless type mixing container for two kinds of contents of the embodiment of the present disclosure is shipped.

[0061] When mixing and using the two kinds of contents accommodated in the airless type mixing container for two kinds of contents of the embodiment of the present disclosure, the push button 44 is deeply pressed as shown in FIG. 4, so as to lower the discharge pump 41.

[0062] When the discharge pump 41 is lowered, the assembly part 33 of the auxiliary container 30 mounted on the trunk 24 of the auxiliary container mounting member 20 moves out of the trunk 24 of the auxiliary container mounting member 20.

[0063] At this time, one of the two kinds of contents flows down through the discharge path 35 formed in the body 31 of the auxiliary container 30 and is mixed with the contents accommodated in the content receiving part 14 of the main container 10.

[0064] In the lowering of the auxiliary container 30, the locking annular rim 32 formed on the outer circumferential surface of the body 31 is locked by the locking annular rim 22 of the trunk 24 of the auxiliary container mounting member 20, and stops the lowering.

[0065] The airless type mixing container for two kinds of contents is to be shaken, so that the two kinds of contents flowing from the auxiliary container 30 may be evenly mixed with the two kinds of contents in the content receiving part 14 of the main container 10.

[0066] When two kinds of contents are evenly mixed, the discharge pump 41 is operated by pressing the push button 44 of the contents discharge pumping member 40, so that as a vacuum is generated in the content receiving part 14 of the main container 10 and the contents are discharged. At this time, the piston 50 positioned in the content receiving part 14 of the main container 10 is pulled up by the vacuum.

[0067] As the piston 50 is pulled up, a state in which the two kinds of contents are adjacent to the discharge pump 41 of the contents discharge pumping member 40 is always maintained.

[0068] The piston 50 that is raised as described above is provided with the concave-type body 51 formed in a concave shape, thereby surrounding the assembly part 33 of the auxiliary container 30 at the time when discharging of the two kinds of contents is completed. In the above-described state, when the piston 50 continues to rise, the auxiliary container 30 is placed in a position, as the initially mounted position, at the lower part of the trunk 24 of the auxiliary container mounting member 20 as shown in FIG. 5.

[0069] The two kinds of contents in the auxiliary container 30 positioned as described above may be discharged without residual amount by the pumping operation of the discharge pump 41.
