Description

직액식 필기구Direct writing instruments

본 고안은 점성이 낮은 저점성잉크를 쓰는 직액식(直液式) 만년필이나 마아킹펜, 싸인펜, 수성볼펜과 같은 직액식 필기구에 관한 것으로, 특히 잉크가 필심부재에 대해 잘 젖어들도록 된 직액식 필기구에 관한 것이다.The present invention relates to a direct-type writing instrument, such as a direct-acting fountain pen, a marking pen, a signing pen, an aqueous ball pen, which uses a low-viscosity ink with low viscosity. It is about.

종래의 이와 같은 직액식 필기구로서는, 저점성잉크가 필심부재에 젖어드는 성능을 높이기 위해 잉크자체에다 계면활성제와 같은 첨가제를 처방하는 방안이 연구되어 실행되고 있었다.As such a conventional liquid writing implement, a method of prescribing additives such as surfactants in the ink itself has been studied and implemented in order to increase the performance of low viscosity ink soaking in the core member.

이렇게 잉크에다 첨가제를 처방하는 방법외에 종래부터 흔히 행해지고 있는 방법으로서는, 황산을 주제(主題)로 한 엣칭용액에다 필심부재를 가온침적한 다음 수세처리를 해서 필심부재의 표면이 거칠어지도록 함으로써 잉크의 표면장력을 저하시켜, 잉크가 필심부재에 대해 잘 젖어들게 하고 있었다.In addition to the method of prescribing an additive to the ink, a method commonly used in the related art is the surface of the ink by heating and immersing the core member in an etching solution based on sulfuric acid, followed by washing with water to roughen the surface of the core member. The tension was lowered to allow the ink to wet the core member well.

그러나 상기 방법에서 사용되고 있는 엣칭용액은 황산을 주제로 하고서 여기에 무수크롬 및 인산으로 이루어진 용액을 혼합하여 사용하기 때문에 독성이 있어서, 피부나 점막을 자극하게 되고, 때로는 화상을 입게될 가능성까지 있어서 취급에 곤란이 따른다고 하는 문제가 있었다.However, the etching solution used in the above method is toxic because sulfuric acid is used as a mixed solution of chromium anhydride and phosphoric acid, which is toxic, which may irritate the skin or mucous membranes and sometimes cause burns. There was problem that difficulty came along.

또 이 엣칭용액은 ABS 이외의 플라스틱으로 만들어진 필심부재에는 그다지 효과가 없다는 것을 알 수 있었다.In addition, it was found that the etching solution was not very effective on the core member made of plastic other than ABS.

이에 본 고안은 이와 같은 사정을 감안하여 안출된 것으로, 상기와 같은 종래의 엣칭용액으로 처리하지 않고 필심부재에 잘 젖어들게 할 수 있는 직액식 필기구를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide a liquid-type writing instrument capable of being wetted by the core member without being treated with the conventional etching solution as described above.

제1도는 본 고안이 적용된 직액식 필기구의 1구성예를 나타낸 단면도이다.1 is a cross-sectional view showing an example of one configuration of a direct-acting writing instrument to which the present invention is applied.

10, 12 : 외통 14 : 필심부재10, 12: outer cylinder 14: core member

18 : 필기부 20 : 잉크유도부재18: writing unit 20: ink induction member

22 : 잉크수용탱크22: ink holding tank

상기와 같은 목적을 달성하기 위해 본 고안에서는, 필심부재에 친수성용액을 도포함으로써 필심부재에 잉크가 젖어드는 성질을 향상시킴과 더불어 그 효과도 지속시킬 수가 있게 되는바, 이는 상기 친수성용액을 필심부재에다 도포하게 되면 잉크체름부에 친수성의 팽윤피막이 형성되기 때문이다.In order to achieve the above object, in the present invention, by applying a hydrophilic solution to the core member, it is possible to improve the wetness of the ink on the core member and to maintain the effect, which is the hydrophilic solution of the core member This is because a hydrophilic swelling film is formed on the ink body part when applied to the film.

본 고안에서 쓰여지는 친수성용액의 주제로서는 폴리비닐알코올이나, 키토산, 아크릴산에스텔, 폴리비닐피로리돈(polyvinyl pirrolidone) 알킬산나트리움, 알긴산프로필렌그리콜, 섬유소그릴콜산나토리움을 들 수 있고, 이들은 단독 또는 조합해서 물에다 용해시킨 수용액으로 만들어 필심부재에다 도포하게 된다. 주제(主題)는 단독으로 하는 것이 효과가 높고 처리도 간단해서 바람직하나, 2가지 이상을 적의 조합시키는 것도 좋다. 여기서 이들 수용액은 모두 독성도 없고 취급도 간단해서 좋다.Examples of the hydrophilic solution used in the present invention include polyvinyl alcohol, chitosan, acrylate, polyvinyl pirrolidone alkyl acid natrium, propylene glycol alginate and natrisofisocol cholate. Combined, it is made into an aqueous solution dissolved in water and applied to the core member. It is preferable that the main body is used alone, because the effect is high and the treatment is simple. All of these aqueous solutions have no toxicity and may be easy to handle.

특히, 친수성용액으로서는 폴리비닐알코올과 키토산, 아크릴산에스텔이 좋고 이들은 도포면에 불용성의 친수성팽윤피막을 형성하기 때문에 그 친수성의 효과를 오래 지속시킬 수가 있게 된다. 또 특히 폴리비닐알코올이 물에의 용해율이 높고 안정성도 높기 때문에 가장 바람직스럽다.Particularly, as the hydrophilic solution, polyvinyl alcohol, chitosan, and acrylic acid acrylate are preferable, and since they form an insoluble hydrophilic swelling film on the coated surface, the hydrophilic effect can be sustained for a long time. In particular, polyvinyl alcohol is most preferable because of its high solubility in water and high stability.

그리고 상기 수용액은 물 99.9~90 중량%에 대해 주제가 0.1~10 중량%의 비율로 용해시키면 되고, 그 중에서도 주제를 약 1중량%로 하는 것이 가장 적합한데, 주제의 비율이 너무 높게 되면 점착성이 높아져 피막이 필심부재에 균일하게 형성되지 못하기 때문에 효과적이지 못하다.The aqueous solution may be dissolved in a proportion of 0.1 to 10% by weight based on 99.9 to 90% by weight of water, and most preferably, about 1% by weight of the main ingredient is used. It is not effective because the film is not formed uniformly on the core member.

또 상기 수용액을 재활용하기 위해 보존성을 유지시킬 필요가 있는 경우에는 보크사이트 N-100을 0.3 중량% 첨가하면 된다.In addition, when it is necessary to maintain preservation property in order to recycle the said aqueous solution, 0.3 weight% of bauxite N-100 may be added.

한편, 필심부재로서는 특히 ABS가 바람직스러우나 폴리프로필렌, 폴리에틸렌, 나일론과 같은 플라스틱에서 젖음성 향상이 현저히 달성될 수 있게 된다.On the other hand, as the core member, ABS is particularly preferable, but the wettability improvement can be remarkably achieved in plastics such as polypropylene, polyethylene, and nylon.

또 같은 ABS 등의 플라스틱으로 만들어진 잉크유도심에 대해서도 필심부재와 마찬가지의 친수성용액으로 도포처리를 함으로써 마찬가지로 잉크가 잉크유도심에 젖어드는 성능을 향상시킬 수가 있게 된다.In addition, the ink induction core made of plastics such as ABS can be treated with the same hydrophilic solution as the core member to improve the performance of the ink soaking in the ink induction core.

제1도는 본 고안이 적용되는 직액식 필기구의 1예의 구성을 나타낸 것으로, 도면에서 참조부호 10은 앞쪽외통으로서, 본 실시예에서는 뒷쪽외통(12)과 착탈될 수 있도록 나사결합되어 있고, 앞족외통(10)내에는 플라스틱으로 만들어진 필심부재(14)가 설치되어 있다.Figure 1 shows a configuration of one example of a direct-acting writing instrument to which the present invention is applied, in the drawing reference numeral 10 is a front outer cylinder, in this embodiment is screwed to be detachable with the rear outer cylinder 12, forefoot outer cylinder Inside the 10, a lead member 14 made of plastic is provided.

이 필심부재(14)는, 필기구의 축선방향으로 뻗은 잉크유도심(20)이 삽입된 중심원통체(14a)와, 이 중심원통체(14a)의 외주에 형성된 빗살형상의 잉크체류부(14b)를 갖추고 있다. 그리고 이 잉크체류부(14b)에는 축선방향으로 뻗은 폭이 좁은 공기-액체교환홈(14c)과, 이 공기-액체교환홈(14c)보다 폭이 넓고 축방향앞쪽으로 가면서 단계적으로 폭이 넓혀지도록 된 환상의 체류홈(14d) 및 공기-액체교환홈(14c)과 반대쪽에서 축선방향으로 뻗은 공기뽑기용 홈(14e)이 형성되어 있다.The core member 14 includes a central cylindrical body 14a into which the ink guide core 20 extending in the axial direction of the writing instrument is inserted, and a comb-shaped ink retention section 14b formed on the outer circumference of the central cylindrical body 14a. Equipped) The ink retaining portion 14b has a narrower air-liquid exchange groove 14c extending in the axial direction, and is wider than the air-liquid exchange groove 14c and gradually widens in the axial direction. The air venting groove 14e extending in the axial direction from the opposite side to the annular staying groove 14d and the air-liquid exchange groove 14c is formed.

필심부재(14)의 앞끝내주면에는 잉크유도심(20)의 앞끝쪽에 잉크유도심(20)과 일체로 구성된 필기부(18)가 보유지지되어 앞쪽으로 돌출되어져 있다. 또 본 실시예에서는 필기부(18)가 잉크유도심(20)과 일체로 구성되어 있으나, 필기부(18)와 잉크유도심(20)이 접촉하도록 하고서 별개체로 구성시켜도 된다.At the front end inner circumferential surface of the pen core member 14, a writing unit 18 integrally formed with the ink guide core 20 is held on the front end of the ink guide core 20 so as to protrude forward. In addition, although the writing part 18 is comprised integrally with the ink induction core 20 in this embodiment, you may make it separate and make the writing part 18 and ink induction core 20 contact.

잉크유도심(20)의 뒤끝쪽에는 저점성잉크를 수용하는 잉크수용탱크(22)가 설치되어 있는데, 이 잉크수용탱크(22)는 교환할 수 있기만 하다면 앞쪽외통(10)에다 착탈될 수 있도록 하거나, 앞쪽외통(10)에 고정적으로 연결하거나, 또는 앞족외통(10)과 일체로 구성시켜도 된다.At the rear end of the ink guide core 20, an ink receiving tank 22 for receiving a low-viscosity ink is installed. The ink receiving tank 22 is detachable from the front outer cylinder 10 as long as it can be replaced. Or, it may be fixedly connected to the front outer cylinder 10, or may be configured integrally with the forefoot outer cylinder 10.

참조부호 30은 캡으로서, 앞쪽외통(10)에다 장착시켜 잉크수용탱크(22) 및 필기부(18)의 기밀성이 유지되도록 하는 것이다.Reference numeral 30 is a cap, which is attached to the front outer cylinder 10 to maintain the airtightness of the ink receiving tank 22 and the writing unit 18.

이상과 같이 구성된 직액식 필기구의 필심부재(14)에는 조립전에 친수성용액의 도포처리가 행해지게 되고, 그에 따라 잉크가 필심부재(14)에 젖어드는 성능이 유지되게 된다.The hydrophilic solution is applied to the core member 14 of the direct writing instrument configured as described above, so that the ink soaked in the core member 14 is maintained.

다음에는 친수성용액에 대해 설명한다.Next, the hydrophilic solution will be described.

폴리비닐알코올(PVA) 1중량%를 물 99중량%에 용해시켜 수용액을 만들어, 이 수용액을 ABS수지로 된 필심부재(14)에다 도포처리해서 약 30분간 건조처리한다. 이 필심부재(14)에 이크유도심(20) 및 필기부(18)를 조립해서 앞쪽외통(10)내에다 설치하고, 이어 잉크수용탱크(22)에 잉크충전충량 약 ⅓쯤의 저점성잉크를 충전시켜 조립한 다음 필기부(18)로 잉크가 유도되어 필기가 가능한지를 확인하고 나서 캡(30)을 장착시킨다.An aqueous solution is prepared by dissolving 1% by weight of polyvinyl alcohol (PVA) in 99% by weight of water. The aqueous solution is applied to the lead member 14 made of ABS resin and dried for about 30 minutes. The ink induction core 20 and the writing unit 18 are assembled to the lead member 14 and installed in the front outer cylinder 10, and then the low viscosity ink having about an ink filling amount in the ink receiving tank 22 is about ⅓. After assembling by assembling the ink is led to the writing unit 18 to confirm whether writing is possible, then the cap 30 is mounted.

이렇게 해서 도포처리한 필심부재(14)를 쓴 직액식 필기구와 도포처리하지 않은 필심부재(14)를 쓰고서 상기와 마찬가지로 조립한 직액식 필기구를 실온보다 30℃가 높은 환경시험기내에 펜끝이 아래로 향하도록 한 상태로 설치하였던바, 기밀성이 있는 캡(30)이 장착되었음에도 불구하고 잉크수용탱크(22)의 내압이 상승하기 때문에 필심부재(14)에 도포처리를 하지 않은 것은 약 5초후에 펜끝에 잉크가 고이는 현상이 생기고, 약 30초후에는 펜끝에 고였던 잉크가 캡(30)으로 옮겨졌다.In this way, the non-coated pen writing instrument using the coated pen core member 14 and the non-coated pen writing member 14 were assembled in the same manner as the above. It was installed in such a state that, even though the airtight cap 30 was installed, the internal pressure of the ink receiving tank 22 increased, so that the coating process was not applied to the core member 14 after about 5 seconds. Ink builds up, and after about 30 seconds, the ink accumulated at the tip of the pen was transferred to the cap 30.

한편, 필심부재(14)에다 도포처리를 한 것은 펜끝에 잉크가 고이는 현상이 일어나지 않고 잉크수용탱크(22)의 내압이 상승함에 따라 잉크수용탱크(22)로부터 잉크가 원활히 필심부재(14)로 옮겨가 잉크체류불(4b)에 저류되게 되었다.On the other hand, the coating treatment on the core member 14 is performed so that ink does not accumulate at the tip of the pen and the ink flows smoothly from the ink receiving tank 22 to the core member 14 as the internal pressure of the ink receiving tank 22 increases. It moved and stored in the ink retention flame 4b.

이상과 같은 환경시험을 1주일간 계속하였으나 펜끝에 잉크가 고이는 일이 조금도 일어나지 않았다.The above environmental test was continued for one week, but no accumulation of ink on the tip of the pen occurred.

마찬가지로 물 99중량%에 대해 키토산 1중량%를 용해시켜 수용액으로 만든 것을 ABS수지로 만들어진 필심부재(14)에다 도포처리한 것으로 상기 폴리비닐알코올의 경우와 마찬가지 실험을 행한 결과, 펜끝에 잉크고임현상이 발생하지 않았고, 주일이 경과한 후에도 잉크고임현상이 전혀 생기지 않았다.Similarly, the same procedure as in the case of polyvinyl alcohol was carried out by dissolving 1% by weight of chitosan in water to 1% by weight of chitosan and applying an aqueous solution to the core member 14 made of ABS resin. This did not occur, and ink pooling did not occur at all even after a week had elapsed.

이상 설명한 바와 같이 필심부재에 친수성액을 도포처리하게 됨으로써 종래와 같이 엣칭용액에다 처리하지 않고서도 필심부재에 잉크가 젖어드는 성능이 향상될 수가 있고 그에 따라 온도가 상승하거나 기압이 변화하여 잉크수용탱크의 내압이 높아지더라도 펜끝에 잉크가 고이는 현상을 피할 수가 있게 된다. 또 필기중 필요이상의 잉크가 공급될 때라도 여잉의 잉크가 원활히 필심부재에 체류하게 되므로 펜끝으로의 잉크토출량이 일정해지게 되어 항상 안정된 필기를 할 수가 있게 된다.As described above, by applying a hydrophilic liquid to the core member, the ink wetting performance of the core member can be improved without treating the etching solution as in the prior art. Accordingly, the temperature increases or the air pressure changes so that the ink holding tank Even if the internal pressure increases, it is possible to avoid the ink accumulation on the pen tip. Further, even when more ink is required during writing, the remaining ink smoothly stays in the core member, so that the amount of ink discharged to the pen tip becomes constant, so that stable writing can be always performed.
