In the present exemplary embodiment, the inner plunger 400 is provided as a separate component from the outer plunger 200 and coupled to the outer plunger 200 as an example, but the spirit of the present invention is not limited thereto. For example, the inner plunger 400 and the outer plunger 200 may be integrally formed. In addition, some components may be integrally formed with other components at a level where the functions of the inner plunger 400 and the outer plunger 200 are maintained. For example, the discharge port 432 may be provided in the outer plunger 200, and the inner plunger 400 may be coupled to the outer plunger 200 and provided in the form of having only the inserting portion 410.

Meanwhile, the discharge port 432 of the inner plunger 510 is selectively shielded by the first valve 510, and the outlet 112 of the outer cylinder 100 is selectively shielded by the second valve 520.

Here, the first valve 510 and the second valve 520 are seated ribs 433 and 113 and the valve fixing protrusions 434 and 122, except that the first valve 510 and the second valve 520 are provided to the fitting portion 230 and the outlet portion 110, respectively. It is fixed by the) and the deformation according to the change in pressure of the front and rear can act on the same principle, will be described in detail below the action of the first valve (510).

The first valve 510 may have a plate shape as a whole and may be provided in an 'H' shape on a cross section. In addition, the first valve 510 may be formed of a material having elasticity so as to be deformable according to pressure changes in the front and the rear. In detail, the first valve 510 may include a shielding surface 512 that is substantially shielding the discharge port 432, and a deformable shielding surface 512, one or more holes formed in the shielding surface 512 to allow fluid to pass therethrough, It may include a support portion 513 formed at the edge of the shielding surface 512 to support the shielding surface 512. In this case, the shielding surface 512 may be provided with a load 518 for more securely sealing the discharge port 432 while allowing the center of gravity to be located on the discharge port 432 side. For example, the load 518 may be formed in a hemispherical shape as a whole and may be inserted into the discharge hole 432 to a predetermined depth.

The shielding surface 512 may be in contact with the seating rib 433 with the first valve 510 in position and the hole 514 may be disposed outside of the inner boundary of the seating rib 433. have. As a result, the discharge port 432 may be closed when the shielding surface 512 is in contact with the mounting rib 433.

In addition, the shielding surface 512 is deformable according to pressure changes in front and rear of the first valve 510. Specifically, when the pressure in front of the first valve 510 (upper side in the drawing) is relatively higher, the first valve 510 is subjected to downward pressure as a whole, and the shielding surface 512 as shown in FIG. 3. Is in close contact with the seating rib 433, and the discharge port 432 is closed. Hereinafter, this state will be referred to as a closed state of the valve.

On the other hand, if the pressure of the rear (lower side in the drawing) of the first valve 510 is relatively higher, the pressure is applied to the shielding surface 512 through the discharge port 432, the shielding surface 512 is shown in FIG. It may be modified as shown in FIG. In this case, the first valve 510 may have a modulus of elasticity at which the displacement may be limited such that the load 518 provided on the shielding surface 512 does not completely exit from the discharge port 432. As it is pushed forward of the shielding surface 512, a space is formed between the shielding surface 512 and the seating rib 433, through which the fluid can enter and exit forward through the hole 514. Hereinafter, this state will be referred to as an open state of the valve.

The support 513 may be held by the valve fixing protrusion 434 so as to be seated on the fitting 230 but not separated therefrom. In addition, the support part 513 may separate the shielding surface 512 from the upper surface of the fitting portion 230 by a predetermined distance so that the shielding surface 512 may be more tightly adhered to the circumference of the mounting rib 433. Here, the support 513 may be provided to maintain the position even in the open state of the valve as shown in FIG. 4, for example, the support 513 may be adhesively fixed.

On the other hand, at least a portion of the outer cylinder 100, the outer plunger 200, the inner cylinder 300, the inner plunger 400, so that the user can check the movement of the cosmetic generated inside the outer cylinder 100 It may be formed of a transparent material. In addition, the applicator 600 is also formed of a transparent material may be provided so that the user can visually check until the moment the cosmetic is discharged from the body (10). As a result, the reliability of the product may be improved or the user may have an aesthetic feeling.

Looking at the assembly process of the dispenser (1) having two discharge modes according to an embodiment of the present invention as described above are as follows.

First, the sealing part 220 is inserted into the outer plunger 200 to form one side of the storage chamber C1, and the inner plunger 400 is coupled to the outer plunger 200. Thereafter, the fluid is injected into the storage chamber C1 through the discharge port 432. In this case, the fluid may be injected to the extent that the storage chamber C1 may be filled so that the fluid may be discharged through the discharge port 432 immediately when negative pressure is generated in the inner space of the outer cylinder 100. In addition, as shown in FIG. 2, the sealing unit 220 may be positioned to contact the pressing unit 210 to maximize the size of the storage chamber C1. In some embodiments, the fluid may be first injected into the inner space of the outer plunger 200, and then the inner plunger 400 may be combined to form the storage chamber C1.

On the other hand, the elastic member 340 may be coupled to the inner cylinder 300 first. The elastic member 340 may be inserted into an inner space of the body 320 so that one end thereof may be supported by the head 310 in a form surrounding the passage part 330. In addition, the locking part 350 may be coupled to the body 320 to prevent the elastic member 340 from being separated.

Since the inner cylinder 300 is inserted into the inner space of the outer cylinder 100 through the inlet 130, it may be arranged so that the head 310 is in close contact with the outlet 110.

Before assembly of the outer plunger 200 to which the inner plunger 400 is coupled, the discharge port 432 of the inner plunger 400 may be shielded by the first valve 510. The first valve 510 may be positioned to be seated on the fitting portion 430 and to be fixed by the valve fixing protrusion 434.

Then, the outer plunger 200, to which the inner plunger 400 is coupled, is inserted into the inner space of the outer cylinder 100 through the inlet portion 130, and the insertion portion 410 of the inner plunger 400 is caught. The external plunger 200 is pressurized to be inserted into the space between the 350 and the passage 330. The movement limiting projection 352 of the locking portion 350 may be formed to be inclined toward the entry direction of the insertion portion 410 so that the insertion portion 410 can be inserted smoothly.

In the state where the insertion part 410 is inserted into the passage part 330 of the locking part 350, the elastic member 340 may be deformed to a predetermined level to apply an elastic force to the insertion part 410. As a result, when there is no external force, the insertion part 352 may always receive an elastic force to the rear, and the state in which the jaw 412 is hung on the movement limiting protrusion 352 may be maintained.

Then, the second valve 520 is installed in the outer cylinder 100. The second valve 520 may be positioned to shield the outlet 112 and to be fixed by the valve fixing protrusion 122.

Thereafter, the applicator 600 may be coupled to and fixed to the applicator support 120 of the outer cylinder 100.

In addition, the lid 20 may be coupled to the outer cylinder 100 after the assembly of the applicator 600 is completed.

In the present embodiment, the dispenser 1 is assembled in the same order as described above, but the spirit of the present invention is not limited thereto, and the dispenser 1 may be assembled in various orders within a range that can be easily changed by those skilled in the art. Could be.

Hereinafter, the operation and effects of the dispenser 1 having two discharge modes according to an embodiment of the present invention will be described.

First, referring to the initial state of the dispenser 1 shown in FIG. 2, the dispenser 1 according to an embodiment of the present invention may be provided in a state in which a cosmetic is filled in the storage chamber C1. The sealing unit 220 may be provided in a retracted state until it reaches the pressing unit 210 to maximize the volume of the storage chamber C1.

In the initial state, the inner cylinder 300 may be provided with the head 310 in close contact with the outlet 110 of the outer cylinder 100 and the inner wall of the outer cylinder 100. As a result, the volume of the variable chamber C2 may be substantially close to zero.

At this time, the insertion portion 410 is pressed by the elastic member 340, so that the jaw 412 may be held in the movement limiting protrusion 352, and the fitting portion 430 may be maintained. May maintain a state spaced apart from the inner cylinder 300 by a predetermined distance. Specifically, the front surface of the fitting portion 430 from which the extension of the insertion portion 410 starts may be provided in a state spaced apart from the seating portion 354.

In this state, the dispenser 1 may have a first discharge mode for intermittently discharging the fluid stored therein and a second discharge mode for discharging continuously.

Specifically, the first discharge mode may be implemented by pushing the pressing unit 210 forward in the initial state, and the second discharge mode may be implemented after the continuous discharge preparation process as described below. . The first discharge mode may be performed even after the second discharge mode is performed. For the convenience of description, the first discharge mode will be described first, and then the first discharge mode will be described.

5 is a view illustrating a state of preparing a continuous discharge of the dispenser of FIG. 1, and FIG. 6 is a view illustrating a continuous discharge state of the dispenser of FIG. 1.

5 and 6, the user may prepare for continuous discharge by retracting the external plunger 200 from an initial state. The user may retract the outer plunger 200 by holding the pressing portion 210 of the outer plunger 200 and pulling it from the outer cylinder 100.

When the outer plunger 200 moves backward, the inner plunger 400 fixed to the outer plunger 200 is also moved, and the inner cylinder 300 is also moved by the interference of the jaw 412 and the movement limiting protrusion 352. Are moved backwards together. Thereby, the volume of the variable chamber C2 can increase.

However, since the volume of the variable chamber C2 in the initial state was substantially zero, the pressure in the variable chamber C2 is reduced by the retraction of the inner cylinder 300. As a result, the pressure of the front of the first valve 510 is lower than that of the rear of the first valve 510, so that the first valve 510 receives the force toward the front, and the discharge port 432 as shown in FIG. 5. Open).

As the discharge port 432 is opened, the fluid stored in the storage chamber C1 is moved forward through the discharge port 432, and the variable chamber C2 is spaced through the space and the passage part 330 between the insertion parts 410. Is moved to). In addition, as the fluid stored in the storage chamber C1 exits, the sealing unit 220 moves forward, and external air is supplied to the external plunger 200 through the vent 212 of the pressing unit 210. Inward to the final pressure compensation can occur.

At this time, the second valve 520 is subjected to a force toward the rear in accordance with the pressure drop of the variable chamber (C2), it is possible to maintain a stable state in which the outlet 112 is closed.

Here, the volume of the variable chamber C2 depends on the amount by which the user moves the outer plunger 200 to the rear. The volume of the variable chamber C2 may substantially correspond to the volume of fluid that has been moved from the storage chamber C1 to the front of the inner cylinder 300. That is, the user may adjust the volume of the fluid filled in front of the inner cylinder 300 by adjusting the displacement of the outer plunger 200.

According to an embodiment, the outer cylinder 100 may be provided with a measuring means such as a scale so that the user can accurately recognize the volume of the variable chamber C2 or the amount of fluid moved forward of the inner cylinder 300. have.

When the user moves the external plunger 200, the same movement of the fluid as described above occurs at the same time, the pressure difference between the storage chamber (C1) and the variable chamber (C2) can be compensated accordingly. Accordingly, when the user stops the movement of the external plunger 200, the negative pressure of the variable chamber C2 is stopped, and the first valve 510 is restored to its original state to close the discharge port 432.

Through this process, the variable chamber C2 may be filled with the fluid, and the fluid filled in the variable chamber C2 may be continuously from the outlet 112 by the user pushing the external plunger 200 forward as shown in FIG. 6. Can be discharged.

Specifically, when the user pushes the outer plunger 200 forward, the inner plunger 400 fixed to the outer plunger 200 presses the elastic member 340, and the elastic member 340 is the head 310. Pressurize. As a result, the head 310 and the body 320 push the fluid in the pressurizing chamber C2, and the pushed-out fluid presses the second valve 520 through the outlet 112.

Here, the elastic modulus of the second valve 520 is provided lower than the elastic modulus of the elastic member 340, so that the second valve 520 is first deformed before the elastic member 340 is deformed. Therefore, the external force applied by the user to the external plunger 200 deforms the second valve 520 to open the outlet 112 before the elastic member 340 is deformed, whereby the fluid in the variable chamber C2 flows through the flow path. It may be discharged to the discharge port 622 through the 610.

The user can push the outer plunger 200 into the inside of the outer cylinder 100 until all the fluid in the variable chamber C2 is discharged, and the fluid from the dispenser 1 continuously while the user exerts an external force. Can be discharged.

When the outer plunger 200 is pushed to the end, all of the fluid in the variable chamber C2 is discharged, and the inner cylinder 300 is brought into close contact with the outlet 112 as in the initial state, which is a standby state for intermittent discharge. to be.

As such, the user can move the desired amount of fluid from the storage chamber C1 to the variable chamber C2 by pulling the outer plunger 200 backward, and then variable by pushing the outer plunger 200 forward. Fluid can be continuously discharged from the chamber C2.

Such continuous dispensing can be used for the user to transfer a large amount of fluid elsewhere.

7 is a view illustrating an intermittent discharge standby state of the dispenser of FIG. 1, and FIG. 8 is a view illustrating an intermittent discharge state of the dispenser of FIG. 1.

7 and 8, after the continuous discharge as described above is completed, the user may discharge the fluid by using the intermittent discharge mode by pressing the pressing unit 210 of the external plunger 200.

When the continuous discharge is completed, the head 310 may be in close contact with the outlet part 110, and the passage part 330 may be disposed to correspond to the outlet 112. When the user presses the pressing unit 210 in such a state, the insertion unit 410 presses the elastic member 340. Since the head 310 is in close contact with the outlet part 110 and can no longer be moved forward, the elastic member 340 is compressed by the inserting part 410 and the fluid stored in the space inside the inserting part 410. Is pushed into the passage part 330 by the first valve 510. In addition, the fluid pushed out of the passage 330 may apply pressure to the second valve 520 to open the outlet 112 and may be discharged to the outside through the flow path of the outlet 112 and the applicator 610.

When the inserting portion 410 presses the elastic member 340 by an external force, and when the external force is removed, that is, when the user removes the force to press the pressing portion 210, the inserting portion 410 of the elastic member 340 It is returned to its original state by the elastic force. At this time, the return position of the insertion portion 410 is the initial position where the jaw 412 interferes with the movement limiting projection 352. As the insertion part 410 returns, the volume of the inner space of the insertion part 410 increases, thereby generating a negative pressure in the inner space and the passage part 330 of the insertion part 410. As a result, the second valve 520 closes the bar outlet 112 which is forced backward. In addition, the first valve 510 is forced to the front bar discharge port 432 is opened, the fluid stored in the storage chamber (C1) through the discharge port 432 into the inner space of the insertion portion 410. Is moved. As a result, the pressure in the storage chamber C1 is reduced, so that the sealing unit 220 moves forward.

At this time, the amount of fluid discharged may be changed by the user pressing the pressing unit 210, the maximum amount is limited by the maximum displacement of the insertion unit 410. That is, after the inner cylinder 300 is in close contact with the outlet 110, there is a limit to the displacement of the pressing unit 210, and the maximum amount of fluid that can be discharged by one discharge operation is also limited accordingly. Can be. Specifically, the maximum displacement of the insertion portion 410 is no longer moved because the insertion portion 430 interferes with the end of the inner cylinder 300, or the first valve 510 or the valve fixing protrusion 434 is the passage portion Interference with 330 may not be moved anymore, or the displacement of the elastic member 340 may be limited by a method such as limited, and thus the maximum amount of fluid that may be discharged may be limited.

Meanwhile, the maximum discharge amount in the intermittent discharge mode determined according to the displacement of the inner plunger 400 inserted into the inner cylinder 300 may be set to be smaller than the discharge amount in the continuous discharge mode described above. Of course, the user may discharge the amount less than the maximum discharge amount in the intermittent discharge mode by reducing the displacement of the external plunger 200 using the continuous discharge mode.

The external plunger 200 may be pressed by the elastic member 340 and then returned to its original state. The user may press and release the pressing unit 210 to discharge the fluid stored therein to the outside. Can be.

Such an operation may be intermittently performed by the user pressing and releasing the pressing unit 210, and the user may repeatedly perform the discharge to discharge the fluid.

The intermittent discharge action as described above may be generated in the same state as before the continuous discharge mode is used, that is, the user presses the pressing unit 210 even in the initial state as shown in FIG. 2.

That is, when the pressing unit 210 is pressed in the initial state, the inner plunger 400 moves to the inner space of the inner cylinder 300 while the inserting portion 410 deforms the elastic member 340 as described above. In response to the displacement of the internal plunger 400, the gas stored inside the insertion part 410 pressurizes the gas stored in the passage part 330, which is discharged to the outside while deforming the second valve 520. Can be.

Subsequently, when the inserting portion 410 is pushed by the restoring force of the elastic member 340, the second valve 520 is discharged by the negative pressure formed in the inner space of the passage portion 330 and the inserting portion 410. The first valve 510 may open the discharge port 432 to move the fluid in the storage chamber C1 to the space inside the insertion part 410.

If this process is repeated several times, the inner space of the inserting portion 410 and the passage portion 330 are eventually filled with fluid, after which the user may discharge from the outlet 112 as the user presses the pressing portion 210. have.

On the other hand, the continuous discharge mode as described above can also be used during the use of the intermittent discharge mode. Specifically, when the user pulls the outer plunger 200 in the state as shown in FIG. 8, the inner cylinder 300 retreats and the variable chamber C2 is formed, and the storage chamber is formed by the sound pressure formed on the variable chamber C2 side.
