DETAILED DESCRIPTION

[0042] Preferred embodiments of the present disclosure will be described in detail below with reference to the attached drawings. The features and the advantages of the present disclosure and the means for implementing them will become apparent through the detailed description of embodiments together with the attached drawings. Here, the embodiments of the present disclosure which will be described below are merely exemplary and are not intended to limit the scope of the present disclosure to the described embodiments. Furthermore, the constituent elements of each of the example embodiments may be combined in various ways in the example embodiment or between the example embodiments, as long as there is no other mention or inconsistency between them.

[0043] As shown in FIGS. 1 to 4, a sharp type paint marker pen according to an example embodiment of the present disclosure includes a main body portion 100, an ink tank 200, an inner rod 300, an ink discharge portion 400, a nib 500, and a cap 600.

[0044] Referring to FIGS. 3 and 4, the main body portion 100 has an exterior form in which it may be held by a user and includes a frame 110 having a pipe shape and a guide plate 120 provided inside the frame 110. On the other hand, the exterior shape of the frame 110 is circular, but may be formed into various shapes such as a triangle, a square, and a hexagon.

[0045] As shown in FIG. 5, the frame 110 may have a first groove 111 which is formed on a left side of an inner diameter thereof and configured to connect the ink discharge portion 400 and a second groove 112 which is formed on a right side of the inner diameter thereof and configured to connect the ink tank 200. At this time, the first groove 111 and the second groove 112 may be formed around the inner diameter of the frame 110. Thus, the ink discharge portion 400 and the ink tank 200 may be smoothly joined to the frame 110.

[0046] The guide plate 120 may be provided integrally inside the frame 110.

[0047] Also, the guide plate 120 may be composed of a vertical portion 121 which is formed on the inner diameter of the frame 110, a horizontal portion 122 which protrudes toward a left side of the vertical portion 121 and into which the inner rod 300 is inserted; and a joint portion 123 which is formed at a left end of the horizontal portion 122 and to which the inner rod 300 is joined. On the other hand, the vertical portion 121 may be formed to have a ring shape, the horizontal portion 122 may be formed to have a pipe shape, and the joint portion 123 may be formed to have a ring shape.

[0048] A fourth protrusion piece 122a may be formed on an inner side of the horizontal portion 122 to which the inner rod 300 is joined. At this time, the fourth protrusion piece 122a is formed to have the shape of a protrusion portion formed in a circumferential direction.

[0049] An inner diameter of the joint portion 123 is formed to be smaller than an inner diameter of the horizontal portion 122. Furthermore, a plurality of flow holes 123a are formed radially in the joint portion 123 so that an ink of the ink tank 200 is discharged to the ink discharge portion 400.

[0050] The ink tank 200 is attached to the inside of the main body portion 100 and has an ink included therein.

[0051] Referring to FIGS. 7 and 8, the ink tank 200 is composed of an ink tank main body 210 and a finishing member 220.

[0052] The ink tank main body 210 is composed of, from a left side to a right side, a front end portion 211, a middle end portion 212, and a rear end portion 213.

[0053] The front end portion 211 is formed to have a pipe shape and a third protrusion piece 211a having a ring shape is formed on an outer diameter of the left end. At this time, the third protrusion piece 211a is formed in the form of a protrusion portion formed in a circumferential direction. Thus, the third protrusion piece 211a and the fourth protrusion piece 122a are formed in the form of the protrusion portion formed in the circumferential direction. Thus, when the ink tank 200 is joined to the frame 110, since the third protrusion piece 211a rides over the fourth protrusion piece 122a of the horizontal portion 122 and the third protrusion piece 211a is located on the left side of the fourth protrusion piece 122a, the ink tank 200 will not fall out easily unless it is pulled forcibly.

[0054] The middle end portion 212 is formed integrally at the rear of the front end portion 211 and is formed so that a diameter thereof increases from the front to the rear.

[0055] Also, as shown in FIGS. 3 and 8, a coil spring S is installed between the vertical portion 121 of the guide plate 120 and the middle end portion 212 of the ink tank main body 210. Thus, if the user applies a force to move the ink tank main body 210 in a direction in which the guide plate 120 is formed, the coil spring S is compressed, and if the user releases the force, the coil spring S returns to an original state thereof.

[0056] The rear end portion 213 is formed to have a pipe shape and has an ink stored therein.

[0057] Also, the rear end portion 213 has a female thread 213a formed in the rear inner diameter to which the finishing member 220 is fastened and a second protrusion piece 213b formed on the outside to be joined to the second groove 112 of the frame 110. At this time, the second protrusion piece 213b may be formed to have a ring shape at a point from the left side to the right side.

[0058] On the other hand, a bead (ball) 230 may be inserted into the ink tank main body 210. The bead (ball) 230 helps so that an ink is mixed well.

[0059] The finishing member 220 is joined in an attachable/detachable manner through screw assembly to the rear end portion 213 of the ink tank main body 210. That is to say, by separating the finishing member 220 from the ink tank main body 210, injecting an ink into the ink tank main body 210, and closing the finishing member 220 to use it, refilling of the ink and the use of it are possible.

[0060] Also, the finishing member 220 is composed of a fastening portion 221 having a male thread 221a formed therein to be fastened to the female thread 213a of the rear end portion 213 and a handle portion 222 formed at the rear end of the fastening portion 221.

[0061] A locking claw 223 protruding outward is formed at a contact point between the fastening portion 221 and the handle portion 222. The locking claw 223 is engaged with the end of the rear end portion 213.

[0062] The inner rod 300 is inserted into the ink tank main body 210 and joined to the guide plate 120 of the main body portion 100.

[0063] Referring to FIG. 9, the inner rod 300 is composed of an inlet portion 310 through which ink flows, a joint portion 320 provided on one side of the inlet portion 310 and joined to the main body portion 100, and a stopper portion 330 provided on the other side of the inlet portion 310.

[0064] The inlet portion 310 is formed to have a cylindrical shape and a plurality of guide protrusions 311 are formed radially on the outer diameter. At this time, the guide protrusions 311 are formed long along the length of the inlet portion 310 and the inner rod 300 is supported by an inner surface of the ink tank 200.

[0065] Also, as shown in FIGS. 9 and 12, a flow path 340 is formed between the exterior of the inlet portion 310 and the front end portion 211 of the ink tank 200 so that an ink is allowed to pass therethrough. The joint portion 320 is formed to protrude from one side of the inlet portion 310 and is composed of an upper joint portion 321 and a lower joint portion 322 which are spaced symmetrically from each other at a set distance. The upper joint portion 321 is formed to protrude upward and an upper insertion groove 321a is formed in the upper portion. The lower joint portion 322 is formed to protrude downward and a lower insertion groove 322a is formed in the lower portion. That is to say, an end portion of the joint portion 123 of the guide plate 120 is inserted into the upper insertion groove 321a and the lower insertion groove 322a formed in the upper joint portion 321 and the lower joint portion 322. Thus, the inner rod 300 is joined to the main body portion 100.

[0066] The stopper portion 330 is composed of a first short claw 331 formed integrally at the rear of the inlet portion 310 and a second short claw 332 formed at the rear of the first short claw 331. The first short claw 331 and the second short claw 332 are formed to have a ring shape.

[0067] Also, the first short claw 331 is formed to have a larger diameter than the inlet portion 310 and the second short claw 332 is formed to have a larger diameter toward the rear.

[0068] As shown in FIGS. 7 and 11, a partition wall 350 is formed on a side surface of the second short claw 332. The partition wall 350 is formed in the longitudinal direction of the marker pen 10 and the vertical cross section is formed to have a circular shape.

[0069] A diameter of the partition wall 350 is formed larger than a diameter of the stopper portion 330. In addition, as shown in FIG. 10, a gap 351 is formed between the partition wall 350 and the ink tank 200 in accordance with a pressing motion of the ink tank 200 and an ink of the ink tank 200 is discharged into the gap 351.

[0070] The ink discharge portion 400 is fixed to the front of the main body portion 100 and an ink which passes through the flow path 340 and the flow holes 123a is absorbed and discharged through the nib 500.

[0071] Referring to FIGS. 5 and 6, the ink discharge portion 400 includes a discharge main body 41 through which an ink which has passed through the flow path 340 of the inner rod 300 and the flow holes 123a is introduced and discharged and a nib fixture portion 420 to which the nib 500 is joined in the front of the discharge main body 410.

[0072] The discharge main body 410 is formed to have a pipe shape in which it is formed stepwise. In addition, an absorbent storage portion 430 which absorbs an ink flowing-in through the flow holes 123a is forcibly joined inside the discharge main body 410.

[0073] The absorbent storage portion 430 is formed to have a cylindrical shape and it is preferable to use a sponge or a filter configured to absorb the flowing-in ink.

[0074] Also, a first protrusion piece 411 is formed on an outer diameter of the discharge main body 410 to fit into the first groove 111 of the main body portion 100 so that the ink discharge portion 400 may be joined to the main body portion 100.

[0075] The nib fixture portion 420 is formed to have a diameter smaller than that of the discharge main body 410. In addition, a joint groove 421 to which the nib 500 is joined is formed inside the nib fixture portion 420.

[0076] The nib 500 is force-fitted into the joint groove 421 of the nib fixture portion 420 and is formed to have a cylindrical shape, but is not limited thereto. On the other hand, the nib 500 is joined to the nib fixture portion 420 so that a part of the nib 500 is exposed to the outside for writing at the time of being joined to the nib fixture portion 420.

[0077] Moreover, the nib 500 is joined so that a rear end thereof is in contact with the absorbent storage portion 430. Thus, an ink absorbed in the absorbent storage portion 430 is discharged through the nib 500.

[0078] On the other hand, a brush may be used instead of the nib. Thus, by using a brush, the brush may be used for watercolors, nail polish, and the like.

[0079] As shown in FIGS. 1 and 4, the cap 600 is joined to the ink discharge portion 400 and seals the nib 500 so that the cap 600 does not dry out or become damaged.

[0080] As described above, the present disclosure states that the middle end portion 212 of the ink tank main body 210 and the outer surface of the stopper portion 330 come into contact with each other so that the ink tank 200 is sealed without being discharged.

[0081] Furthermore, although the ink tank 200 moves longitudinally if the finishing member 220 of the ink tank 200 is pressed, since the inner rod 300 remains in place, the ink tank 200 is opened. At this time, although the ink needs to flow downward, the external atmospheric pressure and surface tension prevent the ink from flowing out.

[0082] Therefore, by adjusting the gap between the ink tank 200 and the inner rod 300, the ink inside the ink tank 200 moves to the lower side, overcomes the surface tension, and flows out to the lower side. Thus, as the ink passes through the narrow space of the gap 351 between the stopper portion 330 formed at the rear of the inner rod 300 and the middle end portion 212 of the ink tank main body 210, the speed increases so that the ink is easily discharged in accordance with Bernoulli's principle.

[0083] Also, if the inner surface of the middle end portion 212 moves away from the outer surface of the stopper portion 330, an ink stored inside the ink tank main body 210 moves to the gap 351 between the stopper portion 330 and the middle end portion 212 and to the flow path 340 between the front end portion 211 and the inlet portion 310.

[0084] Furthermore, as an ink flows into the flow path 340, the ink moves to the absorbent storage portion 430 of the discharge main body 410 through the flow holes 123a of the joint portion 123 and the ink of the absorbent storage portion 430 flows to the nib 500.

[0085] The detailed description of the present disclosure described above has described only specific embodiments thereof. Here, it should be understood that the present disclosure is not limited to the specific forms described in the detailed description, but rather includes all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
