  • Patent Document 2 discloses a structure for limiting the amount of ink entering the gas-liquid exchange area from the ink storage chamber so that a large amount of ink is not pushed out into the reservoir chamber. That is, a partition wall extension extending to the ink storage chamber side is formed in the partition in which the through hole is formed so as to insert the relay core as it is, and the space between the inner surface of the partition extension and the outer peripheral surface of the relay core is formed. In the gap along the axial direction, the ink can be held by capillary force. According to this structure, even if a temperature change occurs, only the ink in the region of the partition extension portion is pushed out, so that a large amount of ink leaks into the reservoir chamber and the coated body side becomes an ink-rich state It is possible to

Alternatively, it can be configured by forming an opening in any part of the partition wall separately from the gap through which the relay core is inserted.
  • the conventional applicator when the posture of the applicator main body is changed, the air inlet in the state of being opened in the storage chamber in which the liquid is stored is always in a state where the liquid is soaked (the air inlet is blocked by the liquid) The posture position of the applicator main body which becomes For this reason, the conventional applicator can not reliably prevent the liquid from leaking out from the air inlet opening to the storage chamber when the air in the storage chamber expands, and this flows into the reservoir chamber, The coated body becomes an ink-rich state, which causes ink leakage.
  • the liquid is held in the gap, so that the sensitivity of the gas-liquid exchange is poor and the writing of the ink on the coated body side is not smooth.
  • the inflow resistance of the air is increased by permitting the inflow of air at the same time as using the ink held in the gap portion. For this reason, if an ink having a high viscosity is used, the flow of air into the storage chamber may not be smoothly performed, and the ink may not be sufficiently ejected by the coated body.
  • the present invention suppresses the outflow of liquid from the storage chamber to the reservoir chamber side (applying body side) regardless of the posture change of the main body, and improves the sensitivity of gas-liquid exchange, and uses a highly viscous liquid.

Since the cup member forms an air passage between the side wall and the main body in the storage chamber, it does not contact the liquid contained inside the side wall. Further, the air passage is in communication with the opening provided in the air guiding member, and the opening is adapted to open into the storage chamber, and is not related to the relay member for transferring the liquid to the application body side. The position allows air to flow into the storage chamber. For this reason, since the transfer resistance of the liquid and air at the time of gas-liquid exchange is eliminated, it becomes possible to perform smooth liquid application on the side of the application body.
  • the liquid level is lower than the opening, regardless of whether the coated body is facing downward or the opposite side of the coating is facing downward. Since the capacity is set to be below, liquid does not dip the opening. Further, by forming the opening in the air guide member so as to open at a position separated from the inner surface of the main body, even if the main body is oriented horizontally, the position of the liquid surface may be lower than the opening. (The liquid level can be set so that the liquid level surely comes below the opening even if the main body becomes horizontal). Therefore, even if the internal pressure of the storage chamber is increased while the main body is horizontal, the reservoir through the opening The liquid is prevented from flowing out to the chamber side.
  • the liquid does not leak to the reservoir chamber because the opening opening to the storage chamber is always below the liquid surface regardless of the change in the posture of the main body. Since the opening is always open in the storage chamber, the transfer of the liquid from the relay member to the applicator becomes smooth.
