[0060] The outer cap 84 is formed in a side thereof a first button insertion hole 844 through which the press button 70 passes.

[0061] Although the present invention shows that the outer cap is undercut coupled to the upper portion of the discharge device frame 60, the outer cap 84 may be coupled in various ways such as screw-coupled, force fitting coupling or ultrasonic bonding, in addition to the undercut.

[0062] The upper cap 80 is further provided in a side thereof with the press button 70 configured to operate the discharge device 20.

[0063] The press button 70 presses the discharge device 20 while horizontally moving back and forth, and is coupled through the first button insertion hole 844 of the outer cap 84 and the first button insertion hole 824 of the inner cap 82.

[0064] The press button 70 is formed with a first diagonal pressing portion 78 to come into close contact with the second diagonal pressing portion 282 of the discharge device 20. In other words, as shown in FIG. 6, when a user presses the press button 70 in a lateral direction, the press button 70 moves to an inner side of the inner cap 82 and the outer cap 84, and thus the first diagonal pressing portion 78 of the press button 70 inwardly pushes the second diagonal pressing portion 282 of the discharge device 20. At this time, since the discharge device 20 is fixed horizontally and only moves vertically, the second diagonal pressing portion 282 moves while being pushed downward by the first diagonal pressing portion 78 so that the discharge pump 20 is pressed.

[0065] The applicator 30 is provided adjacent to the discharge device 20, and used to apply the contents discharged by the discharge device 20 onto the skin.

[0071] FIG. 10 is a sectional view showing a state of pressing both sides of the applicator of the cosmetic container according to the present invention. FIG. 11 is a sectional view showing a state of removing the applicator from the cosmetic container according to the present invention.

[0072] As shown in FIGS. 10 and 11, the applicator 30 may be detachably coupled to the upper cap 80.

[0073] In other words, as shown in FIG. 10, when the user intends to replace the applicator 30, both sides of the applicator 30 are pushed and held using fingers. As shown in FIG. 11, after forcibly pulling out the applicator 30 to separate the applicator 30 from the outer cap 84, the applicator 30 is forcibly inserted into the applicator through-hole 842 of the outer cap 84 while holding both sides of a new applicator 30. Thus, the fitting portion 846 of the outer cap 84 is fitted into the fitting groove 36 of the applicator 30, and a lower end of the applicator 30 is simultaneously mounted in the mounting groove 823 of the inner cap 82.

[0074] As shown in FIGS. 5 and 8, the top cap 40 is detachable to the upper portion of the container main body 10 to expose to the applicator 30 to the outside or conceal the applicator 30 from the outside.

[0075] A fastening groove 42 is formed on an inner periphery of the top cap 40 and coupled to the fastening protrusion 662 of the discharge device frame 60.

[0076] The sealing member 50 is formed inside the top cap 40 to seal the container main body 10.

[0077] The sealing portion 52 is formed at a lower center of the sealing member 50, in which the sealing portion 52 is formed as a groove corresponding to the applicator 30.

[0078] As shown in FIG. 8, both sides of an inlet of the sealing portion 52 of the sealing member 50 may be formed in a round shape so that the applicator 30 may be easily inserted.

[0079] An expansion space 54 is formed outside the sealing portion 52 of the sealing member 50.

[0080] The sealing member 50 is formed of a soft material, and particularly, may be formed of a polypropylene (polypropylene) or polyethylene (polyethylene) that has elasticity.

[0081] As shown in FIG. 8, when the top cap 40 is coupled to the upper portion of the container main body 10, the applicator 30 formed of a flexible material comes into tight contact with and is inserted into the sealing portion of the sealing member 50. At this time, the sealing portion 52 of the sealing member 50 comes into tight contact with an outer peripheral surface of the applicator 30 while opening to the outside by the expansion space 54. Accordingly, a sealing force of the container main body 10 is more improved.

[0082] FIG. 9 is a sectional view showing a state in which the sealing protrusion is formed inside the sealing member of the cosmetic container according to the present invention.

[0083] A sealing protrusion 522 of the sealing member 50 may inwardly protrude from the sealing portion 52 of the sealing member 50. As shown in FIG. 9, the sealing protrusion 522 is inserted into the discharge port 32 of the applicator 30 when the top cap 40 is coupled to the upper portion of the container main body 10, so that the sealing force of the container main body 10 further increases.

[0084] A method of assembling the cosmetic container equipped with the top cap having improved sealing force configured as described above will be described as follows.

[0085] In order to assemble the cosmetic container equipped with the top cap having improved sealing force according to the present invention, as shown in FIGS. 3 and 4, the contents are filled in the container main body 10.

[0086] Next, the opening 11 of the container main body 10 is mounted therein with the discharge device 20 including the cylinder 21, the suction valve plate 22, the sealing member 23, the vertical moving member 24, the elastic member 25, and the operation discharge tube 26, the operation discharge ring 27, and the press member 28.

[0087] Next, the discharge device frame 60 is screw-coupled to the opening 11 of the container main body 10, in which the press member 28 of the discharge device 20 passes through the through-hole 61 of the discharge device frame 60.

[0088] Then, the upper cap 80 including the inner cap 82 and the outer cap 84 is coupled to the upper portion of the discharge device frame 60, so that the upper cap 80 is coupled to surround the upper portion of the discharge device frame 60 and the discharge device 20.

[0089] Next, the press button 70 is coupled to the first button insertion hole 844 of the outer cap 84 and the second button insertion hole 824 of the inner cap 82, so that the first diagonal pressing portion 78 of the press button 70 comes into tight contact with the second diagonal pressing portion 282 of the discharge device 20.

[0090] Next, the fitting portion 846 of the outer cap 84 is fitted to the fitting groove 36 of the applicator 30 while passing the lower portion of the applicator 30 through the applicator through-hole 842 of the outer cap 84, and simultaneously the lower end of the applicator 30 is mounted in the mounting groove 823 of the inner cap 82.

[0091] Finally, the top cap 40 is fastened to the upper portion of the discharge device frame 60, in which the sealing member 50 is coupled into the top cap 40.

[0092] Accordingly, the assembly of the cosmetic container equipped with a top cap having improved sealing force according to the present invention is finished.

[0093] Usage of the above assembled cosmetic container equipped with the top cap having improved sealing force will be described as follows.

[0094] In order to use the cosmetic container equipped with the top cap having improved sealing force according to the present invention, first, the top cap 40 is separate from the container main body 10 as shown in FIG. 5.

[0095] Then, as shown in FIG. 6, when the side surface of the press button 70 is pressed, the press button 70 moves to the inside of the upper cap 80, and simultaneously the first diagonal pressing portion 78 of the press button 70 pushes the second diagonal pressing portion 282 of the press member 28 to move the press member 28 downward.

[0096] When the press member 28 moves downward as described above, the vertical moving member 24 coupled to the lower portion of the press member 28 and the operation discharge tube 26 coupled to the lower portion of the vertical moving member 24 also moves downward. At this time, since the operation discharge ring 27 fitted to the outer side of the operation discharge tube 26 comes into close contact with the inner surface of the cylinder 21, only the operation discharge tube 26 moves downward, so that a gap is generated between the operation discharge tube 26 and the operation discharge ring 27, thereby forming a passage through which the contents are discharged.

[0097] Then, when the vertical moving member 24 is pressed more, the operation discharge ring 27 touches the lower end of the vertical moving member 24, and moves downward together with the operation discharge tube 26, thereby reducing a volume inside the cylinder 21. Accordingly since a discharge pressure is generated in the cylinder 21, the suction valve plate 22 closes the contents suction hole 21a, and the contents accommodated in a temporary storage space in the cylinder 21 come out between the operation discharge tube 26 and the operation discharge ring 27, pass through the inside of the operation discharge tube 26, and be discharged to the outside via the discharge hole 822 of the inner cap 82, and the discharge passage 34 and the discharge port 32 of the applicator 30.

[0098] As shown in FIG. 7, when the pressure of the press button 70 is released, the vertical moving member 24 moves upward due to the elasticity of the elastic member 25 that elastically supports the vertical moving member 24, and the operation discharge tube 26 coupled to the lower portion of the vertical moving member 24 moves upwards. At this time, as an expansion protrusion wheel 262 formed at an outer side of a lower end of the operation discharge tube 26 pulls up the operation discharge ring 27, the gap between the operation discharge tube 26 and the operation discharge ring 27 is blocked, so that the operation discharge tube 26 and the operation discharge ring 27 move upward together, and thus the volume inside the cylinder 21 increases, thereby generating a vacuum pressure.

[0099] Then, the suction valve plate 22 opens the contents suction hole 21a formed at the bottom surface of the cylinder 21 by the vacuum pressure generated inside the cylinder 21, accordingly, the contents accommodated in the container 14 of the container main body 10 flow into the cylinder 21 through the contents suction hole 21a, so that the soft inner container 14 is crushed, and simultaneously air is introduced through the air inlet groove 122 formed in the outer container 12 of the container main body 10.

[0100] Then, after the contents discharged through the discharge port 32 of the applicator 30 are used, the top cap 40 is closed and stored or carried.

[0101] As shown in FIG. 8, when the top cap 40 is coupled to the upper portion of the container main body 10, the applicator 30 formed of a flexible material is inserted into the sealing portion 52 of the sealing member 50 while coming into tight contact with the sealing portion 52.

[0102] At this time, as the discharge passage 34 formed inside the applicator 30 is contracted, the applicator 30 is tightly inserted into the sealing portion 52 of the sealing member 42. Simultaneously, the sealing portion 52 extends to the outside by the expansion space 54, so that the sealing force is further improved.

[0103] In addition, as shown in FIG. 9, when the sealing protrusion 522 is formed in the sealing portion 52 of the sealing member 50, the sealing protrusion 522 is inserted into the discharge port 32 of the applicator 30.

[0104] Then, when the user intends to replace the applicator 30, as shown in FIG. 10, both sides of the applicator 30 are pushed and held using fingers. As shown in FIG. 11, after forcibly pulling out the applicator 30 to separate the applicator 30 from the outer cap 84, both sides of a new applicator 30 are pushed and held, and the applicator 30 is forcibly inserted into the applicator through-hole 842 of the outer cap 84. Thus, the fitting portion 846 of the outer cap 84 is fitted into the fitting groove 36 of the applicator 30, and a lower end of the applicator 30 is simultaneously mounted in the mounting groove 823 of the inner cap 82.

[0105] Herein, the description of the present invention is merely one embodiment for carrying out the cosmetic container equipped with the top cap having improved the sealing force, and the present invention is not limited to the embodiment. The exemplary embodiments have been proposed and set forth in the aforementioned description, however the present invention should not be construed as limited thereto, and it will be apparent to those having ordinary skill in the art in that many different substitutions, deformations and modifications are available within the scope without departing from the present invention.
