본 발명은 도 1 내지 도 3에 도시되는 바와 같이, 외주면에 나선 결합부를 갖는 주입구(11)가 상부에 형성되고, 주입구(11)의 측면에 관통구멍이 형성되는 용기(10)와; 용기(10)의 주입구(11)에 나선결합되도록 내주면에 나선 결합부가 형성되고, 내주면과 소정 틈새를 두고 깔때기 형태의 격리부재(21) 상단이 일체로 연결되며, 반경이 축소된 격리부재(21)의 하단에 용기(10)의 내측 하부까지 연장되는 공기통로(22) 상단이 탈착 가능하게 연결되고, 상부에 공기구멍(a)이 형성되는 덮개(23)가 구비되는 뚜껑(20)과; 용기(10)의 내벽과 공기통로(22) 사이에서 하단부가 용기(10)의 바닥 가까이 까지 연장되고 상단은 굽혀져 주입구(11) 측면의 관통구멍을 관통해 프린터 카트리지로 연결되는 잉크공급관(30)으로 이루어지는 것을 구성상의 기본 특징으로 한다.1 to 3, the container 10 is formed in the upper injection hole 11 having a spiral coupling portion on the outer peripheral surface, the through hole is formed on the side of the injection hole (11); The spiral coupling portion is formed on the inner circumferential surface to be helically coupled to the inlet 11 of the container 10, and the upper end of the funnel-shaped separating member 21 is integrally connected to the inner circumferential surface with a predetermined gap, and the insulating member 21 is reduced in radius. A lid (20) having a lid (23) formed at an upper end of the air passage (22) extending to an inner lower portion of the container (10) at a lower end thereof, and having an air hole (a) formed thereon; Between the inner wall of the container 10 and the air passage 22, the lower end portion extends to the bottom of the container 10 and the upper end is bent to penetrate through the through hole on the side of the inlet 11 to be connected to the printer cartridge 30. It consists of) as a basic characteristic of a structure.

상기와 같이 구성되는 본 발명은 주입구(11)를 통해 잉크를 용기(10)에 주입시킨 후, 뚜껑(20)의 내주면과 격리부재(21) 사이의 틈새에 링 형태의 고무링(24)을 끼우고 격리부재(21)의 하단에 공기통로(22)를 연결한 상태로 주입구(11)에 뚜껑(20)을 덮고 돌리면 나선을 따라 이동하여 주입구(11)를 기밀하게 닫게 되며, 격리부재(21)는 용기(10) 내부의 잉크 속에 잠기게 되어, 격리부재(21)와 공기통로(22) 안쪽 공간은 덮개(23)의 공기구멍(a)을 통해 외부와 통하게 되고, 격리부재(21)와 공기통로(22) 바깥쪽과 용기(10) 내부 사이의 공간은 격리된 공간이 되게 된다.According to the present invention constituted as described above, after injecting ink into the container 10 through the inlet 11, a ring-shaped rubber ring 24 is formed in a gap between the inner circumferential surface of the lid 20 and the isolation member 21. Insert the cover 20 to the inlet 11 while the air passage 22 is connected to the lower end of the isolation member 21, and then turn and move along the spiral to close the inlet 11 in an airtight manner. 21 is immersed in the ink in the container 10, the space inside the isolation member 21 and the air passage 22 is communicated with the outside through the air hole (a) of the cover 23, the isolation member 21 ) And the space between the outside of the air passage 22 and the inside of the container 10 becomes an isolated space.

상기한 본 발명은 프린터로 인쇄를 하면 프린터 카트리지로 잉크공급관(30)을 통해 공기통로(22) 바깥쪽 잉크가 공급되게 되는데, 이때 용기(10) 내부에는 부(-)압이 생기게 되어, 공기구멍(a)과 연통된 공기통로(22) 안쪽의 잉크가 공기통로(22) 바깥쪽으로 이동하고 공기구멍(a)으로부터 공기통로(22) 상부에 외부의 공기가 유입되어 부(-)압이 제거되게 된다.According to the present invention, when the printer is printed, ink outside the air passage 22 is supplied to the printer cartridge through the ink supply pipe 30 to the printer cartridge. The ink inside the air passage 22 communicating with the hole a moves to the outside of the air passage 22, and outside air flows from the air hole a to the upper portion of the air passage 22 so that negative pressure is reduced. Will be removed.

이때 공기통로(22) 바깥쪽 공간은 밀폐상태이기 때문에 공기통로(22) 안쪽의 잉크 량이 먼저 줄어들고, 공기통로(22) 안쪽 하단까지의 잉크가 다 공급된 경우, 공기구멍(a)으로 유입된 공기가 공기통로(22)의 바깥쪽으로 유입되면서 공기통로(22)의 바깥쪽 잉크 량이 줄어들게 된다.At this time, since the space outside the air passage 22 is sealed, the amount of ink inside the air passage 22 is reduced first, and when all the ink to the bottom of the inside of the air passage 22 is supplied, the ink flows into the air hole a. As air enters the outside of the air passage 22, the amount of ink outside the air passage 22 is reduced.

한편, 인쇄작업과 상관없이 외부 온도의 변화에 의해 용기(10) 내부에 압력이 상승하는 경우, 공기통로(22) 바깥쪽에 있던 잉크가 공기구멍(a)과 연통된 공기통로(22) 안쪽과 격리부재(22)로 이동하고 공기통로(22) 안쪽과 격리부재(22)의 압력은 공기구멍(a)을 통해 외부로 제거되므로, 자연스럽게 평형을 유지하도록 하므로, 필요치 않은 잉크가 카트리지로 공급되거나 용기 외부로 잉크가 흘러내리는 것을 방지한다.On the other hand, when the pressure rises inside the container 10 due to the change in the external temperature regardless of the printing operation, the ink in the outside of the air passage 22 and the inside of the air passage 22 in communication with the air hole a Moving to the isolation member 22 and the pressure inside the air passage 22 and the pressure of the isolation member 22 are removed to the outside through the air hole (a), so that it is naturally balanced, so that unnecessary ink is supplied to the cartridge or Prevents ink from flowing out of the container.

즉, 온도 상승으로 용기(10) 내부의 잉크 체적이 커지면 용기(10) 내부 공간에 팽창압력이 발생하게 되는데, 이때 공기통로(22) 바깥쪽 잉크가 공기통로(22) 안쪽과 격리부재(22)로 이동하여 팽창압력을 수용하므로 용기(10) 내부의 압력을 제거해 주고, 온도 하강으로 용기(10) 내부의 잉크 체적이 작아지면 용기(10) 내부 공간에 부(-)압이 발생하게 되는데, 이때는 공기구멍(a)을 통해 자동으로 공기가 유입되고 공기통로(22) 안쪽의 잉크가 공기통로(22) 바깥쪽 공간으로 이동하여 부(-)압을 수용하므로 용기(10) 내부의 부(-)압을 제거해 주어, 인쇄작업을 수행하지 않는 한 잉크가 카트리지 쪽으로 흘러가는 것을 방지한다.That is, when the ink volume inside the container 10 increases as the temperature rises, an expansion pressure is generated in the interior space of the container 10. At this time, the ink outside the air passage 22 is inside the air passage 22 and the isolation member 22. Move to the) to accommodate the expansion pressure to remove the pressure inside the container 10, the negative pressure is generated in the interior space of the container 10 when the ink volume inside the container 10 is reduced by the temperature decrease. At this time, the air is automatically introduced through the air hole (a) and the ink inside the air passage 22 moves to the space outside the air passage 22 to receive negative pressure so that the inside of the container 10 may be negative. The negative pressure is removed to prevent ink from flowing into the cartridge unless a print job is performed.

용기(10)의 관통구멍에는 관통구멍 내주면과 잉크공급관(30)의 외주면 사이를 기밀하게 밀폐하는 밀폐용 밀폐고무(31)가 끼워지며, 잉크공급관(30)의 출구가 굴절된 연결구(32)를 통해 카트리지로 연결되는 잉크공급관(30)에 연결된다.The through hole of the container 10 is fitted with a sealing sealing rubber 31 for hermetically sealing between the inner circumferential surface of the through hole and the outer circumferential surface of the ink supply pipe 30, and the connector 32 in which the outlet of the ink supply pipe 30 is refracted. It is connected to the ink supply pipe 30 which is connected to the cartridge through.
