본 발명은 필기구에 관한 것으로, 더욱 상세하게는 액상저장부와 흡수저장부 및 심체로 구성되는 필기구에 있어서 심체와 접하는 흡수저장부에 조밀부를 형성하여서 점성력에 의한 흡수력 의하여 흡수저장부에 임시 저장되어 있는 잉크가 모세관현상에 의하여 심체로 원활하게 공급될 수 있도록 함을 목적으로 한 것이다.The present invention relates to a writing instrument, and more particularly, in a writing instrument consisting of a liquid storage unit, an absorption storage unit, and a core, a dense unit is formed in the absorption storage unit in contact with the core, and is temporarily stored in the absorption storage unit by absorption force due to viscous force. The purpose of the ink is to be able to supply smoothly to the core by the capillary phenomenon.

일반적으로, 필기구는 잉크가 저장되는 잉크탱크와, 상기 잉크탱크의 잉크를 모세관 현상을 통하여 인출하여서 필기가 이루어지게 하는 심체으로 이루어진 것이다.In general, the writing instrument is composed of an ink tank in which ink is stored, and a core body which draws ink from the ink tank through capillary action to perform writing.

한편, 상기한 바와 같이 잉크탱크로부터 심체가 직접 잉크를 공급받는 경우에는 심체를 통한 잉크 유출의 조절이 어려워 상기 심체와 잉크탱크의 사이에 잉크탱크의 잉크를 임시 저장하였다가 공급할 수 있는 흡수저장부를 형성하여 잉크의 과동한 유출을 방지할 수 있도록 하고 있다.On the other hand, when the core is directly supplied with ink from the ink tank as described above, it is difficult to control the outflow of ink through the core, the absorption storage unit that can temporarily store the ink in the ink tank between the core and the ink tank and then supply To prevent excessive spillage of ink.

그러나, 상기한 바와 같이 심체와 잉크탱크의 사이에 흡수저장부를 형성한 종래의 필기구는 흡수저장부의 흡수력이 심체에 의한 모세관력보다 커서 잉크의 유출이 원활하게 이루어지지 않는 문제점이 있었다.However, as described above, the conventional writing implement having the absorbent storage portion between the core and the ink tank has a problem that the absorption force of the absorbent storage portion is greater than the capillary force caused by the core so that the ink does not flow smoothly.

이에, 본 발명은 상술한 문제점을 해결하기 위하여 창출한 것으로, 심체와 잉크탱크 사이에 위치되는 흡수저장부의 심체 접촉부위에 다른 부위보다는 흡수력이 저하되고 모세관력이 강화되는 조밀부로 형성한 것이다.
Accordingly, the present invention has been made to solve the above-described problems, it is formed in the core contact portion of the absorbent storage portion located between the core and the ink tank as a dense portion that absorbs less than other areas and the capillary force is strengthened.

이하, 첨부된 도면에 의하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings.

한편, 본 발명의 실시에 있어 흡수저장부(20)의 심체접촉부 측에 유출조밀부(21)가 형성되도록 가압할 수 있게 심체(10)의 후단부를 돌출 형성하고, 상기 심체(10)의 후단부를 지지하는 후방캡(40)에 심체(10)의 외주연을 감싸 가이드할 수 있게한 가이드부(41)를 형성하여 실시할 수 있는 것이다.Meanwhile, in the practice of the present invention, the rear end of the core 10 is formed to protrude so that the outflow dense portion 21 is formed on the core contact portion side of the absorption storage portion 20, and the rear end of the core 10 is formed. It can be carried out by forming a guide portion 41 to be wrapped around the outer periphery of the core 10 to guide the rear cap 40 to support the portion.

그리고, 본 발명의 실시에 있어 흡수저장부(20)의 탱크접촉부 측에 유입조밀부(22)가 형성되도록 가압할 수 있게 잉크탱크(30)의 전방측에 결합되는 탱크캡(50)의 배출구(51)를 돌출 형성한 것이다.Then, in the practice of the present invention, the outlet of the tank cap 50 is coupled to the front side of the ink tank 30 to be pressurized so that the inlet compact portion 22 is formed on the tank contact portion side of the absorption storage unit 20 The protrusions 51 are formed.

또한, 상기 탱크캡(50)은 잉크탱크(30)에 결합시 탄성 끼움결합에 의하여 기밀상태를 유지할 수 있게 잉크탱크(30) 결합부측에 결속되는 환상의 링으로 이루어진 탄성결속부(52)를 형성하여 실시할 수 있는 것이다.In addition, the tank cap 50 has an elastic binding portion 52 made of an annular ring that is bound to the coupling portion side of the ink tank 30 so as to maintain an airtight state by elastic fitting when coupled to the ink tank 30. It can form and implement.

본 발명의 또 다른 실시예로는 흡수저장부(20)의 유입조밀부(22)와 유출조밀부(21)가 근접함으로 인한 잉크의 과다유출을 방지할 수 있게 유출조밀부(21)로부터 유입조밀부(22)가 이격되게 탱크캡(50)의 배출구(51)를 중심으로부터 이격 형성하여 실시할 수 있는 것이다.According to another embodiment of the present invention, the inflow dense part 22 and the outflow dense part 21 of the absorbent storage part 20 are introduced from the outflow dense part 21 to prevent excessive leakage of ink due to the proximity. It can be carried out by forming the outlet 51 of the tank cap 50 spaced apart from the center so that the dense portion 22 is spaced apart.

본 발명의 또 다른 실시예로는 심체(10)의 후방캡(40)과 탱크캡(50) 사이에 흡수저장부(20)를 수용하는 관체의 흡수저장실(60)을 형성하고, 상기 흡수저장실(60)의 일측에 탱크캡(50)으로부터 유출된 잉크가 유입될 수 있게한 잉크유입구(61)를 형성하여 실시할 수 있는 것이다.In another embodiment of the present invention is formed between the rear cap 40 and the tank cap 50 of the core 10 to form the absorption storage chamber 60 of the tubular body for receiving the absorption storage unit 20, the absorption storage chamber One side of the (60) can be carried out by forming an ink inlet 61 to allow the ink flowing out of the tank cap 50 to be introduced.

한편, 필기선단(70)의 일측에서 후방캡(40)과 탱크캡(50)의 배출구(51)을 관통하여 잉크탱크(30)로 연통되어서 잉크의 유출로 인한 공기의 공급이 이루어지게한 공기 공급통로가 형성되어 있는 것이다.On the other hand, the air is passed through the rear cap 40 and the discharge port 51 of the tank cap 50 at one side of the writing tip 70 to communicate with the ink tank 30 to supply air due to the outflow of ink. Supply passage is formed.

이하, 본 발명에 의한 사용과정에 대하여 설명하면 다음과 같다.Hereinafter, the use process according to the present invention will be described.

상기한 바와 같이 잉크가 액상으로 저장되는 잉크탱크(30)와, 상기 잉크탱크(30)의 잉크를 흡수 저장할 수 있게 다공질재로 이루어진 흡수저장부(20)와, 상기 흡수저장부(20)에 저장된 잉크를 모세관력에 의하여 인출하여서 필기가 이루어지게 하는 심체(10)로 이루어진 필기구에 있어서, 상기 흡수저장부(20)에서 심체(10)로의 잉크유동이 원활한 모세관유동되게 흡수저장부(20)의 심체접촉부측에 다공질 기공이 다른 부위의 다공질 기공 보다 조밀한 기공으로 이루어진 유출조밀부(21)를 형성한 본 발명을 사용하게 되면, 잉크가 액상으로 저장되어 있는 잉크탱크(30)에서 잉크가 탱크캡(50)의 배출구(51)를 통하여 흡수저장부(20)로 유입되게 된다. 이때, 상기 배출구(51)가 흡수저장부(20)로 돌출형성되어 유입조밀부(22)가 형성된 경우에는 모세관 현상에 의하여 신속하게 흡수저장부(20)로 공급되어서 충진되게 되는 것이다.As described above, the ink tank 30 in which the ink is stored in the liquid phase, the absorption storage unit 20 made of a porous material to absorb and store the ink in the ink tank 30, and the absorption storage unit 20 In the writing instrument consisting of the core 10 for taking out the stored ink by capillary force to be written, the absorption storage unit 20 so that the ink flow from the absorption storage unit 20 to the core 10 smooth capillary flow When using the present invention in which the porous dense portion on the core contact portion side of the porous densities formed in the outflow dense portion 21 consisting of denser pores than the pores of the other portion, the ink in the ink tank 30 in which the ink is stored in the liquid state It is introduced into the absorption storage unit 20 through the outlet 51 of the tank cap 50. At this time, when the discharge port 51 is formed to protrude into the absorbent storage unit 20 and the inlet dense unit 22 is formed, it is rapidly supplied to the absorbent storage unit 20 by the capillary phenomenon and filled.

그리고, 상기 흡수저장부(20)에 저장된 잉크는 필기로 인한 심체(10)에서의 잉크유동이 발생하게 되면 상기 심체(10)와 유출조밀부(21)의 모세관력에 의하여 원활하고 신속하게 유동되어서 필기가 원활하게 이루어지게 되는 것이다.And, the ink stored in the absorption storage unit 20 flows smoothly and quickly by the capillary force of the core 10 and the outflow dense part 21 when the ink flow in the core 10 due to writing occurs The writing is smoothly done.

한편, 필기구의 사용과정에 있어 심체(10) 방향으로의 충격하중이 발생하여 잉크탱크(30)의 잉크에 충격유동이 발생하게 되면 흡수저장부(20)의 탱크측에 형성한 유입조밀부(22)가 충격유동에 의한 잉크의 급속한 유동을 억제하여서 잉크의 과다유동이 방지되는 것이다.On the other hand, when the impact load occurs in the direction of the core 10 in the process of using the writing instruments and the impact flow occurs in the ink of the ink tank 30, the inflow dense portion formed on the tank side of the absorption storage unit ( 22) suppresses rapid flow of ink due to impact flow, thereby preventing excessive flow of ink.

따라서, 본 발명은 흡수저장부에 유출조밀부를 형성하므로서 다공질의 기공에 의한 흡수력에 의하여 저장되어 있는 잉크가 기공이 조밀하게 형성되어 흡수력보다 모세관력이 강화되므로서 심체를 통하여 잉크의 유출이 균일하고 원활하게 이루어져 필기가 원활하게 이루어지는 것이다.Therefore, in the present invention, by forming an outflow dense portion in the absorption storage unit, the ink stored by the absorbing force by the porous pores is densely formed in the pores so that the capillary force is strengthened rather than the absorbing force, so that the outflow of ink through the core is uniform. The writing is done smoothly.

또한, 흡수조장부에 유입조밀부를 형성하므로서 잉크탱크의 잉크가 원활하게 흡수저장부로 모세관유동되며 충격하중에 의하여 잉크의 급속유동을 차단하여서 잉크의 과다유출을 효과적으로 방지한는 매우 유용한 것이다.In addition, it is very useful that the ink of the ink tank smoothly capillary flows into the absorption storage part by blocking the rapid flow of the ink by the impact load by forming the inflow dense part in the absorption storage part.
