(en)CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of Korean application No. 10-2016-68365 filed on Jun. 1, 2016 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
BACKGROUND
The present invention relates to a heterogeneous contents mixing container with improved productivity and sealing ability, and more particularly, to a heterogeneous contents mixing container where a first content receiving member is divided into an upper part and a lower part while rotating a shoulder formed on an outer side of the mixing container and at the same time, a push button coupled to an upper end of a pump is exposed to an upper part of the mixing container. In addition, the first content receiving member includes an upper separation cap and a lower fixing cap, and first and second connection pipes are integrally formed on the upper separation cap and the lower fixing cap, respectively. The process of assembling a content suction passage is simplified by directly inserting the second connection pipe into the first connection pipe to form the contents suction passage, thereby improving the productivity and the sealing ability of the product.
In general, there are many cases where two or more different contents are mixed and used in order to multiply the efficacy or effect of cosmetics or medicines contained in a container.
However, after the contents are mixed and then the mixed contents are stored in a single container, when the mixed contents are put into circulation or kept, a chemical reaction may occur in the container to cause the mixed contents to coagulate or precipitate, so that a discharge error may occur or the mixed contents may be discolored or deteriorated.
Thus, according to the related art, different contents are kept in separate containers, respectively. Then, after the inlets of the separate containers are opened, the contents are mixed in a separate container for use.
However, the above-described method may be inconvenient to be used and may cause loss of the container. In addition, when the contents stored in separate containers are put into a single container, the contents may flow down and contaminate the surroundings.
Therefore, in recent years, a mixing container has been developed and used such that different contents may be mixed and used by user's operation when necessary, where the different contents are kept in a single container while being isolated from each other and stored in a single container.
A homogeneous contents mixing container according to the related art has been disclosed in Korean Registered Utility Model No. 20-0270335, as shown in FIG. 1 . The homogeneous contents mixing container includes an outer container, a liquid discharging part rotatably coupled to an upper portion of the outer container to discharge contents, sealing means coupled to a lower portion of the outer container and having a separation membrane, and an inner container formed therein with a containing space, where a lower cover is mounted, around the lower portion of the outer container to be movable upward, and a cuttable virgin is attached to an upper portion of the lower cover.
However, the virgin is first removed to use the heterogeneous contents mixing container according to the related art. Then, after pressure is applied to the lower cover to break the separation membrane, the upper cover is separated and then, the liquid discharge part must be pressed. Therefore, it is inconvenient to use the heterogeneous contents mixing container according to the related art.
To solve the problems described above, as shown in FIG. 2 , a cosmetic container for mixing two kinds of contents had been disclosed in Korean Registered Utility Model No. 28-0475601 applied by and issued to the applicant of the present application.
The cosmetic container according to the related art includes a first content receiving member 1 containing content 1 and including an upper separation cap 1 a and a lower fixing cap 1 b ; a second content container body 2 for containing content 2 ; a mixing outlet part 4 provided on a lower portion of the second content container body and serving as an outlet of mixed content 3 obtained by mixing the content 1 and the content 2 ; a pump housing 5 coupled to an upper end of the first content receiving member and provided on both sides thereof with guide projections which are fitted into a lift spiral groove of a lift guide tube 6 and a vertical groove of a shoulder 7 ; an airless pump 8 coupled to an inside of the pump housing; and a push button 9 formed on an upper end of the airless pump.
Therefore, when the shoulder 7 is rotated, while the first content receiving member 1 is divided into upper and lower parts, the content 1 is mixed with the content 2 contained in the second content container body 2 , and at the same time, the push button 9 protrudes upwardly of the cosmetic container.
However, according to the above-mentioned related art, the discharge tube 1 c , which passes through the upper separation cap 1 a while being connected to the lower side of the airless pump 8 and is inserted into the lower fixing cap 1 b , is additionally formed to serve as the moving passage of the mixed contents 3 , so that the assembling process of the product is complicated and thus, the productivity of the product is deteriorated.
In addition, according to the related art, since a sealing structure is not provided between the pump housing 5 and the lift guide pipe 6 , the content leaks through the gap between the pump housing 5 and the lift guide pipe 6 . Even though an O-ring is further coupled into the gap, the O-ring is pulled up when the pump housing 5 moves slidingly.
In addition, according to the related art, since the O-ring 3 is mounted on one side of the lower fixing cap 1 b in order to seal the first content receiving member 1 , it is difficult to assemble the O-rings 3 to the lower fixing cap 1 b , so that a defective product may be produced.
SUMMARY

To use the heterogeneous contents mixing container with improved productivity and sealing ability according to the present invention, the container body 10 is first held with one hand, and the shoulder 30 is rotated counterclockwise with the other hand.
As shown in FIG. 6 , when the shoulder 30 is rotated counterclockwise, the lift member 50 is rotated together with the shoulder 30 . In this case, while the lift protrusion 52 of the lift member 50 slides in the state that the lift protrusion 52 is inserted into the spiral groove 42 of the lift guide member 40 , the lift protrusion 52 moves up.
As described above, when the lift member 50 moves up, the first latch protrusion wheel 54 lifts up the second latch protrusion wheel 64 of the pump housing 60 and, at the same time, the third latch protrusion wheel 66 of the pump housing 60 lifts up the fourth latch protrusion wheel 226 of the upper separation cap 22 , such that the pump housing 60 , the discharge pump 70 and the upper separation cap 22 move up together with the lift member 50 .
In this case, since, the lower fixing cap 24 is fixed by the through-hole protrusion 122 of the container body 10 , while the upper separation cap 22 and the lower fixing cap 24 are separated from each other, the first content contained in the first content receiving member 20 is mixed with the second content contained in the container body 10 .
Thereafter, as shown in FIG. 7 , when the push button 30 is pushed, while the push button 80 moves down, the vertical moving member 76 and the piston 74 of the discharge pump 70 coupled to the lower portion of the push button 80 move down.
In this case, since the piston 75 of the discharge pump 70 is tightly closed to the inner side surface of the cylinder 71 , while only the piston 74 moves down, a gap is generated between the piston 74 and the piston ring 75 so that the content discharge passage is generated.
Then, when the push button 80 is continuously pushed, the piston ring 75 is pressed by the lower end of the vertical moving member 76 , so that the volume of the cylinder 71 is reduced as the piston ring 75 moves down together with the piston 74 . Thus, while the content suction hole 78 of the check valve 72 is closed by the discharge pressure in the cylinder 71 , the content contained in the cylinder 71 is output between the piston 74 and the piston ring 75 , so that the content passes through the content discharge passage 86 of the push button 80 and discharged through the discharge outlet 82 .
As shown in FIG. 8 , if the pressure on the push button 80 is released, the push button 80 move up by the elasticity of the elastic member 77 elastically supporting the push button 80 and the vertical moving member 76 coupled to the lower side of the push button 80 and the piston 74 also move up. In this case, as the expansion protrusion wheel formed on the lower end of the outer side of the piston 74 lifts up the piston ring 75 , while the gap between the piston 74 and the piston ring 75 is blocked, the piston 74 and the piston ring 75 move up together, so that the volume of the cylinder is increased, thereby generating a vacuum pressure.
Thereafter, while the check valve 72 is lifted up by the vacuum pressure generated from the inside of the cylinder 71 , the content suction hole 78 formed on the bottom surface of the cylinder 71 is opened, so that the first and second contents mixed in the container body 10 are introduced into the cylinder 71 .
In this case, after the first and second contents mixed in the container body 10 are introduced into the suction space 92 through the suction space inlet 13 , the first and second contents are introduced into the cylinder through the suction passage 28 formed by the first connection pipe 222 of the upper separation cap 22 and the second connection pipe 242 of the lower fixing cap 24 .
As described above, the heterogeneous contents mixing container with improved productivity and sealing ability described in this disclosure is an illustrative purpose only, and the present invention is not limited thereto. Thus, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art within the spirit and scope of the present invention and they will fall within the scope of the present invention.
