본 고안은 젤(gel)상이나 액상의 잉크를 사용하는 필기구의 구성에 관한 것으로 특히 잉크를 수용함에 있어서 별도의 심을 구비시키지 않고 필기구몸체내에 직접 잉크가 용입되도록 수용공간을 마련하고 팁과 잉크수용공간 사이의 유로 및 수용공간의 후단에는 각각 수용공간과 유로, 수용공간과 외부를 선택적으로 개폐시켜 주기 위한 개폐용변을 볼을 구비시킴과 동시에 필기구몸체의 선단에 끼워진 구금의 후단연부에는 소정갯수의 잉크유도홈을 요설하여 줌으로써 필기구의 구성단순화로 인한 제작공정의 단축, 제조원가의 절감등으로 인한 생선성의 향상을 기함과 아울러 충격에 의한 잉크의 역류방지 및 필기시외부와의 연통으로 인한 팁으로의 잉크공급의 원활성과, 전체 잉크의 하중이 팁으로 직접 가해지는 것으로 중간에서 일차 완화시켜 주로도록 하여 팁에서의 잉크 과유출로 인한 잉크맺힘현상(속칭 잉크눈꼽)이 방지되어 필기선의 굵기가 일정하게 되어 양호한 필기상태의 유지 및 필기거리의 연장등의 기할 수 있도록 한 것이다.The present invention relates to the composition of writing instruments using gel or liquid ink. In particular, there is no need to provide a separate core for accommodating the ink. At the rear end of the flow path and the receiving space therebetween, the ball is provided with opening and closing sides for selectively opening and closing the receiving space and the flow path, the receiving space and the outside, respectively, and a predetermined number of inks at the rear edge of the cap fitted to the tip of the writing instrument body. By providing a guide groove, it improves the fish properties by shortening the manufacturing process due to the simplification of the composition of writing instruments and reducing manufacturing costs, and also prevents ink backflow due to impact and ink as a tip due to communication with the outside during writing. For ease of supply, the entire ink load is applied directly to the tip to moderate the primary This prevents ink clumping due to ink spillage at the tip, so that the thickness of the writing line is constant so that a good writing state can be maintained and the writing distance can be extended.

종래에 알려지고 있는 필기구는 대개 필기구몸체인 외관체 내에는 선단에 팁이 삽지되고 내부에 잉크가 용입된 심이 설치되는 것이며 또한 심 내부의 잉크는 팁의 유로를 통해 필기볼에 접촉되는 상태이고 잉크의 후방에는 계면장력이 높은 유성의 역류방지액을 유입시켜 심의 후방을 폐쇄시켜 주는 것으로 역류방지액은 심으로의 외부의 공기유입을 차단하여 잉크의 소모에 따라 점차 내측으로 잉크를 따라 이동되는 것으로 이와 같이 구성되는 종래의 필기구는 다음과 같은 문제점이 노출되는 것이다.The writing instruments known in the art are usually provided with a tip inserted in the tip of the pen and an ink penetrated therein in the outer body which is the writing instrument body. The ink inside the shim is in contact with the writing ball through the flow path of the tip and the ink In order to close the back of the seam by introducing an oil-based backflow prevention fluid with high interfacial tension, the backflow prevention fluid is moved along the ink gradually as the ink is consumed by blocking the inflow of external air to the shim. Conventional writing instruments configured as described above are exposed to the following problems.

⊙ 필기구몸체내에 별도의 심을 삽입설치해야 하는 것이므로 심의 구성이 추가되므로 제작 및 조립공정이 많아지고 그만큼 단가가 상승하게 되어 생산성이 저하되며⊙ Since a separate shim must be inserted and installed in the writing instrument body, the structure of the shim is added, which increases the manufacturing and assembly process and increases the unit price.

⊙ 필기구가 낙하되어 충격을 받을때 팁에 삽지된 볼이 충격에 의해 미세하게 유동되어 팁내부가 외부와 연통될 경우 진공상태가 해제되어 공기가 유입 되므로 심내부의 잉크가 역류방지액을 통해 외부로 유출되는 경우가 허다하여 심을 못쓰게 되므로 자원의 낭비를 초래하였으며 심내부는 역류방지액에 의해 외부와 밀폐되어 진공상태를 이루고 있게 되므로 필기사용시 팁에 전달되는 잉크의 소고도가 늦어지게 되어 대기시간이 필요하게 되며 또한 필기시 잉크의 전하중이 직접 팁을 통해 볼에 전달되게 되므로 필요이상의 잉크압이 부여되어 필기시 잉크의 과유출현상에 의한 필기상태의 불량, 잉크의 과소모, 잉크의 건조지연 등의 문제점이 노출되므로 제품의 신뢰성이 저하되는 것이었다.⊙ When the writing instrument falls and is impacted, the ball inserted in the tip is finely flowed by the impact. If the tip is in communication with the outside, the vacuum is released and air is introduced. Since it leaks to many cases, it can't use the core, which is a waste of resources, and the inside of the core is sealed with the outside by the backflow prevention liquid to form a vacuum state. In addition, since the charge of ink is transferred to the ball through the tip directly during writing, more ink pressure is applied, resulting in poor writing condition due to overflow of ink during writing, excessive consumption of ink, and drying of ink. Problems such as delays are exposed, thereby reducing the reliability of the product.

본고안은 상기와 같은 종래의 제반문제점을 해결보완하기 위하여 안출된 것으로 첨부된 도면에 의거하여 본 고안의 구성을 상세히 설명하면 다음과 같다.The present invention is made in order to solve the above-mentioned conventional problems as described above in detail the configuration of the present invention based on the accompanying drawings.

내부에 관통상태의 잉크수용공간(2)이 구비되고 볼받침턱(4) 중앙의 잉크유출로(5)에 의해 잉크수용공간(2)과 연통되는 구금삽지공(3)을 갖는 필기구 몸체(1)와; 선단에 공지의 팁(T)과 볼(B)이 삽지되고 후단연부에 내부의 잉크유로(12)에 연통되도록 소정갯수의 잉크유도홈(11)이 형성된 상태로 상기구금삽지공(3)에 고정삽지되는 구금(10)과; 상기 필기구몸체(1)의 후단에 고정상태로 삽지되며 잉크수용공간(2)을 외부와 연통시키기 위해 공기유입로(23)를 관통형성시키되 공기유입로(23)의 중간에는 받침턱(21)과 이탈방지용 돌조(22)를 구비시킨 마개체(20)와; 상기 볼받침턱(4)과 팁(T)의 사이 및 마개체(20)의 받침턱(21)과 돌조(22) 사이에 유동가능하게 위치되며 잉크유출로(5)와 공기유입로(23)를 선택적으로 개폐시켜 주기 위한 개폐용 변볼(30)(31)을 각각 결합구성하여서된 것이다. 도면중 미설명부호(40)는 캡이다.The writing instrument body 1 having an ink receiving space 2 in a penetrating state therein and having a detention insertion hole 3 communicating with the ink receiving space 2 by the ink outlet 5 at the center of the ball supporting jaw 4. )Wow; The tip T and the ball B are inserted at the front end and fixed to the prison insertion hole 3 with a predetermined number of ink guide grooves 11 formed to communicate with the ink flow path 12 therein at the rear end. The detention being inserted 10; Inserted in a fixed state at the rear end of the writing instrument body (1) and through the air inlet (23) to communicate the ink receiving space (2) with the outside, but in the middle of the air inlet (23) a support step (21) And stopper 20 provided with a separation prevention protrusion 22; It is located between the ball supporting jaw 4 and the tip (T) and between the supporting jaw 21 and the projection 22 of the stopper 20, the ink outlet (5) and the air inlet (23) Opening and closing side balls (30) and (31) for selectively opening and closing the will be configured to each. In the figure, reference numeral 40 is a cap.

이와 같이 구성된 본고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured as described in detail as follows.

제2도는 본고안의 작용효과를 설명하기 위한 일부 절개단면도로써 필기구몸체(1)를 팁(T)이 위로 가게 세워놓은 상태에서는 변볼(30)(31)이 자중에 의해 하강되어 실선과 같이 볼받침턱(4)과 받침턱(21)에 접촉됨으로 인해 잉크유출로(5)와 공기유입로(23)를 폐쇄시켜 주게 되는 것으로 잉크수용공간(2)내의 잉크는 외부로의 역류가 방지되고 구금삽지공(3) 및 팁(T)의 잉크유로(12)에 있던 잉크 또한 잉크수용공간(2)으로의 역류가 억제되는 것으로 종래와 같이 필기구 자체에 충격이 가해져 팁(T)으로부터 미세하게 공기가 유입되더라도 변볼(30)(31)이 외부로 통하는 모든 출구를 막고 있게 되므로 잉크의 역유출이 방지되는 것이어서 필기구의 오염이나 잉크의 낭비를 방지하고 종래와 같이 심 자체가 무용화되어 교체해야 되는 번거로움 및 자원의 낭비를 예방할 수 있는 것이다.Figure 2 is a partial incision cross-sectional view for explaining the effect of this paper, the ball (30) 31 is lowered by its own weight in the state that the writing instrument body (1) with the tip (T) up, the ball bearing as a solid line By contacting the jaw 4 and the support jaw 21, the ink outflow passage 5 and the air inflow passage 23 are closed. The ink in the ink receiving space 2 is prevented from flowing back to the outside and detained. The ink in the ink passage 12 of the insertion hole 3 and the tip T is also suppressed from flowing back into the ink receiving space 2, and as a result, the writing instrument itself is impacted as in the prior art, and air from the tip T is minutely discharged. Even if it is introduced, since the toilet balls 30 and 31 are blocking all the outlets to the outside, the backflow of ink is prevented to prevent contamination of the writing implement or waste of ink, and the shim itself becomes obsolete and replaces as before. Prevention of waste and resources That would be.

한편 필기를 행하는 상태에서는 변볼(30)(31)이 자중에 의해 하강되어 볼받침턱(4)과 받침턱(21)에서 덜어지면서 일점쇄선과 같이 구금(10) 후단의 잉크유로(12)의 내연부와 마개체(20)의 돌조(22)에 각각 접촉됨으로써 잉크 유출로(5)와 공기유입로(23)를 모두 개방시켜 주게 되는 것으로 잉크수용공간(2)내의 잉크는 공기유입로(23)의 개방으로 인한 외부와의 연통상태로 인해 월활한 동작으로 잉크수용공간(2)내에서 이동하여 잉크유출로(5)를 통과하게 되는 것이며 구금(10)의 잉크유로(12)내에는 전기한 필기구가 거꾸로 세워질때 변볼(30)에 의해 잉크수용공간(2)으로 이동되지 못한 잉크가 그대로 남아 있게 되므로 필기구를 바로 세워줌과 동시에 이 잉크가 바로 팁(T)내의 볼(B)에 접촉하게 되므로 곧바로 필기가 가능하게 되는 것이며 한편 잉크수용공간(2)내의 잉크는 변볼(30)에 의해 막혀 있는 구금(10)의 잉크유로(12)로 곧바로 유입되지 못하고 일차로 하중에 의한 가압력이 완하된 뒤에 잉크유도홈(11)을 통해 천천히 잉크유로(12)로 유입되는 것이어서 조래와 같이 잉크의 전하중의 직접 팁(T)의 볼(B)에 가해짐으로써 잉크의 과유출로 인한 속칭 잉크눈꼽이 발생되지 않게 되므로 필기선의 굴기가 일정하여 필기상태가 양호하고 잉크의 불필요한 소모가 방지되므로 필기거리가 연장됨과 아울러 제품의 신뢰도 및 사용효과가 개선되는 것이다.On the other hand, in the state of taking notes, the ball 30 and 31 are lowered by their own weight and are removed from the ball support jaw 4 and the support jaw 21, and the ink flow path 12 of the rear end of the detention 10, like a dashed line, is removed. By contacting each of the inner periphery and the protrusion 22 of the plug 20, the ink outflow passage 5 and the air inflow passage 23 are both opened. Due to the communication state with the outside due to the opening of 23), it moves in the ink accommodating space 2 and passes through the ink outflow passage 5 in a smooth operation, and in the ink passage 12 of the detention 10 When the writing instrument is turned upside down, the ink which has not been moved to the ink receiving space 2 by the toilet ball 30 remains as it is, so that the writing instrument is standing upright and the ink immediately contacts the ball B in the tip T. It will be possible to write right away, and in the ink containing space 2 The ink does not flow directly into the ink passage 12 of the detention 10 blocked by the side ball 30, and after the pressing force due to the load is released, the ink flows slowly into the ink passage 12 through the ink guide groove 11. As it is introduced, it is applied to the ball (B) of the direct tip (T) in the charge of the ink like the sputum so that the nickname of ink due to the overflow of the ink does not occur, so the writing line is uniform and the writing state is good. Since unnecessary consumption of ink is prevented, writing distance is extended, and reliability and use effect of the product are improved.
