The nozzle part 280 may provide a space inside so that the brush part 220 and the slip part 290 can be inserted.

Both ends of the nozzle unit 280 are open, so that the inner space provided by the nozzle unit 280 may communicate with the outside.

The brush 220 may be wetted with ink delivered from the relay core 230 .

The brush unit 220 may be in direct contact with the user's body.

The slip part 290 may have a column shape providing a predetermined space therein.

For example, the slip portion 290 may have a cylindrical shape.

However, the shape of the slip portion 290 is not limited thereto, and various modifications are possible at a level obvious to those skilled in the art.

The position limiting part 260 may include a first position limiting part 261 and a second position limiting part 262 extending in one direction from one end of the first position limiting part 261 .

An insertion hole formed through the position limiting part 260 in the longitudinal direction of the position limiting part 260 may be formed in the position limiting part 260 .

For example, a first insertion hole h261 may be formed in the first position limiting part 261 , and a second insertion hole h262 may be formed in the second position limiting part 262 . .

The second position limiting part 262 may be connected to one end of the first position limiting part 261 , and a shielding part 270 may protrude from the other end of the first position limiting part 261 . have.

The position limiting part 260 may have a discharge hole that penetrates from the periphery of the insertion hole to the periphery of the position limiting part 260 .

Specifically, a discharge hole may be formed in the first position limiting part 261 by penetrating from the periphery of the first insertion hole h261 to the perimeter of the first position limiting part 261 .

A plurality of the discharge holes may be formed in the first position limiting part 261 .

For example, the discharge hole may include a first discharge hole h261-1 and a second discharge hole h261-2 spaced apart from the first discharge hole h261-1.

The first discharge hole h261-1 may be aligned with the second discharge hole h261-2 in a longitudinal direction of the first position limiting part 261 .

However, without being limited thereto, the number of the discharge holes may be variously modified at a level obvious to those skilled in the art.

The width of the first discharge hole h261-1 with respect to the longitudinal direction of the position limiting part 260 is a distance between the first discharge hole h261-1 and the second discharge hole h261-2. could be longer than

For this reason, the flow of air through the discharge hole may be smooth.

The first position limiting part 261 has an inside of the position limiting part 260 forming the insertion hole to be connected to one end of the position limiting part 260 facing the discharge hole and the receiving space S211. A portion of the side surface may be recessed to form the bypass flow passage Q261.

A width of the bypass passage Q261 in a circumferential direction of the insertion hole may be greater than a width of the discharge hole in a circumferential direction of the insertion hole.

The bypass passage Q261 may be connected to all of the discharge holes.

For this reason, the discharge hole may not be blocked by the relay core 230 .

The shielding part 270 may be formed by protruding backward from the other side of the first position limiting part 261 .

A portion of the side surface of the shielding part 270 may be penetrated and opened to form a flow space S270 .

It is possible to prevent the ink in the accommodating space S211 adjacent to the first position limiting part 261 from flowing directly into the insertion hole by the shielding part 270 .

When the relay core 230 is moved from the reverse position to the forward position, the ink in the accommodation space S211 adjacent to the first position limiter 261 may suddenly flow into the insertion hole.

The shielding part 270 can effectively prevent such a problem.

However, since the shielding part 270 provides the flow space S270 , it is possible to prevent the ink in the accommodation space S211 from completely flowing into the insertion hole.

The external force applying units 241 and 242 are moved on the receiving space S211 by the housing unit 210 being moved so that the relay core 230, which is the reverse position, is positioned to the forward position, and the relay core ( An elastic part that is connected to the striking part 241 and the position limiting part 260 and the relay core 230 for applying an external force to 230, elastically contracting when the relay core 230 is positioned in the forward position ( 242) may be provided.

One end of the relay core 230 may have a pointed shape.

The other end of the relay core 230 may have a wider shape.

This may be a portion on which the elastic part 242 is seated.

6 is a combined cross-sectional view of an eyeliner according to an embodiment of the present invention.

Referring to FIG. 6 , the nozzle part 280 is inserted into the housing part 210 so that a part thereof is located in the arrangement space S212 , and the other part may be exposed to the outside.

The brush unit 220 may be inserted into the nozzle unit 280 , some may be located in the arrangement space S212 , and the rest may be exposed to the outside.

One end of the second position limiting part 262 may be inserted into the lower end of the nozzle.

For this reason, it is possible to prevent the ink existing in the second insertion hole h262 and the brush unit 220 from leaking into the arrangement space S212 outside the nozzle.

In a state in which the slip part 290 is inserted into the second insertion hole h262, the relay core 230 is formed in the first insertion hole h261, the second insertion hole h262, and the slip part ( 290) may be inserted into the inner space.

One end of the relay core 230 may be connected to the brush part 220 .

One end of the elastic part 242 may be in contact with and connected to the other side of the first position limiting part 261 while being extrapolated to the shielding part 270 .

The other end of the elastic part 242 may be connected to the other end of the relay core 230 to be hooked.

The elastic part 242 may be an elastic member.

For example, the elastic part 242 may be a coil spring.

However, without being limited thereto, the type of the elastic part 242 can be variously modified at a level obvious to those skilled in the art.

The striking part 241 may be located in the accommodation space S211.

For example, the striking part 241 may have a circular ball shape.

However, without being limited thereto, the shape of the striking strike can be variously deformed in a number of weeks obvious to those skilled in the art.

When the ink is discharged to the outside through the brush unit 220 , air as much as the volume in which the ink is discharged must be introduced into the receiving space S211 .

External air may be introduced into the arrangement space S212 between the outer surface of the nozzle, the second position limiting part 262 and the second position limiting part 262 and the inner surface of the housing part 210 . have.

The air introduced to the outer surface of the second position limiting part 262 may flow into the bypass passage and the first insertion hole h261 through the discharge hole, and then may be introduced into the accommodation space S211.

7 is a view for explaining the function of the bypass unit of the position limiting unit provided in the cartridge of the eyeliner according to an embodiment of the present invention.

Referring to FIG. 7 , the diameter of the relay core 230 may be smaller than the diameter of the first insertion hole h261 .

Accordingly, the relay core 230 may be horizontally positioned on the first insertion hole h261.

Since the relay core 230 is inclined to one side, the first insertion hole h261 and the discharge hole may be separated from each other without communicating with each other.

If there is no bypass passage Q261, air introduced through the discharge hole may not flow into the first insertion hole h261.

External air flowing through the discharge hole may flow into the accommodation space S211 through the discharge hole and the bypass passage part Q261.

As an example, the diameter of the relay core 230, the width of the bypass flow passage Q261 in the circumferential direction of the first insertion hole h261, and the discharge hole in the circumferential direction of the first insertion hole h261 The ratio of the width may be 1:0.5 to 0.9:.

However, the present invention is not limited thereto, and the above ratio may be variously modified at a level obvious to those skilled in the art.

8 is a view for explaining the movement of the position of the relay core provided in the cartridge of the eyeliner according to an embodiment of the present invention.

FIG. 8(a) is a diagram illustrating a state in which the relay center 230 is in a reverse position.

When the relay core 230 is in the reverse position, the elastic part 242 may not contract.

When the relay core 230 is in the reverse position, the slip portion 290 may contact the rear surface of the second insertion hole h262.

However, the present invention is not limited thereto, and the slip portion 290 may not come into contact with the rear surface of the second insertion hole h262.

When the relay center 230 is in the backward position, the slip part 290 may be located at the rearmost position among possible positions.

Referring to FIG. 8( b ), when the user shakes the housing part 210 , the striking part 241 may be moved in a translational position back and forth on the receiving space S211 .

As the striking unit 241 moves in a forward direction, the striking unit 241 may strike the rear end of the relay core 230 .

Referring to FIG. 8( c ), the relay core 230 may be moved in a forward direction by the hitting of the striking unit 241 , and may be moved to a forward position.

Due to this, the elastic part 242 may be contracted.

By moving the forward position of the relay core 230 , the pearl between the relay core 230 and the position limiting part 260 may be moved to the brush part 220 .

When the relay core 230 is moved from the reverse position to the forward position, the slip part 290 extrapolated to the relay core 230 may also slide on the inner surface of the second position limiting part 262 .

The slip portion 290 may be configured to facilitate movement of the position of the relay core 230 .

Since the nozzle part 280 is extrapolated to the second position limiting part 262 , the pearl or ink present in the insertion hole is prevented from moving in the second position limiting part due to the pressure change according to the forward and backward position movement of the relay core 230 . It is possible to effectively prevent discharge to the outside through between the 262 and the nozzle unit 280 .

9 is a view for explaining the relationship between the relay core and the slip portion provided in the cartridge of the eyeliner according to an embodiment of the present invention.

Referring to FIG. 9 , the slip part 290 (refer to FIG. 6 ) is formed from an inner surface of the slip body 291 and the slip body 291 providing a space inside which the relay core 230 is inserted. A slip protrusion 292 protruding in an inward direction may be provided.

The slip protrusion 292 may be plural.

For example, the number of slip protrusions 292 may be four.

However, the number of the slip protrusions 292 is not limited thereto and can be variously modified at a level obvious to those skilled in the art.

Each of the slip protrusions 292 may be spaced apart from each other to form a discharge space S290 through which ink and/or pearls flow.

Specifically, upper surfaces of the slip protrusion 292 are connected to the relay core 230 , and the slip protrusion 292 presses the relay core 230 , so that the relay core 230 is the slip body part. It is possible to prevent position movement in the forward and backward directions based on (291).

Ink or pearl may be moved to the brush unit 220 through the discharge space (S290).

The slip unit 290 may be configured to not only implement the position movement of the relay center 230 with respect to the second position limiting unit 262 but also allow movement of ink and/or pearls.

The forward direction may refer to a direction from the accommodation space S211 toward the arrangement space S212 .

The rear direction may mean a direction opposite to the front direction.

In the accompanying drawings, in order to more clearly express the technical spirit of the present invention, components that are not related to or inferior to the technical spirit of the present invention are briefly expressed or omitted.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and it is understood that various changes or modifications can be made within the spirit and scope of the present invention. It is intended that such changes or modifications will be apparent to those skilled in the art, and therefore fall within the scope of the appended claims.
