Description of the Related Art

In general, as a method of using a liquid-state cosmetic preparation such as cosmetics that it is preferable to use by a small amount and an accurate amount at a time including eye cream, a method of individually packaging preparations in capsules, etc., by the amount to be used at each time of use has been used in the related art.

However, such an individual packaging method has a problem of inefficiency because even after a user uses a cosmetic preparation, a relatively large amount of cosmetic preparation remains in a capsule.

In order to overcome the problem of such an individual packaging method, a configuration designed to take out and use a cosmetic preparation every time a user uses the preparation using a taking-out instrument such as a common pipette or syringe or a taking-out instrument having the configuration of a push pump after the preparation is put into a container has been disclosed.

Meanwhile, the importance of eco-friendly materials is becoming increasingly prominent, and soft springs made of eco-friendly materials are being developed to replace metal springs. However, soft springs developed with eco-friendly materials are showing performance degradation issues compared to metal springs.

As a solution for solving this issue, there is a need for an improvement approach that allows for easy separation and discharge because it uses metal springs and can easily extract existing metal springs that cannot be extracted due to a fixed coupling type.

In detail, when the pumping unit 300 is moved down and performs pumping the outer cap stopper operation, protrusion 122 is positioned in the region of a first hole 311 and moved up or down with the pumping unit 300. Meanwhile, when the pumping unit 300 is rotated in a specific direction, for example, clockwise to stop the pumping unit 300 at a specific position, the outer cap stopper protrusion 122 is inserted into the third hole 313 through a first hole 311 and a second hole 312 shown in FIG. 4. As a result, the outer cap stopper protrusion 122 is inserted in the third hole 313 and there is almost no space between the third hole 313 and the outer cap stopper protrusion 122, so the pumping unit 300 can be positioned at the position.

The pipette unit 200 is, as shown in FIG. 2, coupled at the upper end inside the inner cap body 111 and operation of the pumping unit 300 can send cosmetic liquid into the pipette unit 200 or can discharge cosmetic liquid out of the pipette unit 200.

In this embodiment, the pipette unit 200, as shown in FIG. 2, includes: a pipette coupling body 210 having a horizontal body 211 disposed inside the inner post 112 of the inner cap 110 and a vertical body 212 formed downward on the bottom of the horizontal body 211; and a pipette member 220 coupled to the vertical body 212.

The pumping unit 300 can send cosmetic liquid stored in the container body into the pipette member 220 or can discharge cosmetic liquid in the pipette member 220 out of the pipette member 220 by moving up and down in the inner cap 110 and the outer cap 120 by rotation force by a user.

In this embodiment, the pumping unit 300, as shown in FIG. 2, includes: a wall body 310 disposed in the cap unit 100 to move up and down; a pumping cap 320 moving up and down with the wall body 310 and detachably coupled to the wall body 310; an elastic member 330 disposed in the inner cap and elastically supporting the pumping cap 320; and a piston member 340 coupled to the pumping cap 320 and moving up and down with the pumping cap 320.

The wall body 310 of the pumping unit 300 is moved up and down on the inner wall of the outer cap body 121, and, as shown in FIG. 5, may have a hollow cylindrical shape.

In this embodiment, the first hole 311, the second hole 312, and the third hole 313 are formed at the wall body 310 to be connected to each other, as shown in FIG. 5, and the areas of the holes are increased in order of the first hole 311, the second hole 312, and the third hole 313. In this embodiment, in order to fix the position of the pumping unit 300, the outer cap stopper protrusion 122 of the outer cap 110, as described above, is moved to the third hole 313 through the first hole 311 and the second hole 312 and then locked in the third hole 313, whereby the position of the pumping unit 300 can be fixed.

Further, in this embodiment, a groove 314 may be formed on the outer wall of the body of the pumping cap 320, as shown in FIG. 4. In this embodiment, the groove 314 may be positioned under the first hole 311.
