Description

  The present invention relates to a writing instrument and an ink replenishing device. More specifically, the present invention relates to a writing instrument and an ink replenishing device having an ink occluding body in a barrel and capable of replenishing the ink occluding body.

  DESCRIPTION OF RELATED ART Conventionally, the writing implement and the ink replenishing container which can perform ink replenishment easily by inserting a pen point side in an ink container are shown (refer patent document 1).

JP-A-6-86980

  The refillable writing implement and the ink replenishing container disclosed in Japanese Utility Model Laid-Open Publication No. 6-86980 absorb ink from the pen tip by immersing the pen tip having a capillary force, such as fiber or felt, in the ink to absorb the ink. Since it is absorbed into the body, it takes a long time to fill with only the capillary force of the pen tip, and ink cannot be replenished promptly.

  In addition, the publication also states that ink can be replenished from the air groove, but the ink sucked from the air groove is stored in the ink absorbing body along the pen tip, and also from the pen tip and the air groove. At the same time as the ink suction, the air inside the barrel corresponding to the ink suction amount is released from the air groove to the outside, so that a long time is required for filling.

  SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned conventional problems, and to provide a writing instrument and an ink replenishing apparatus which can quickly and quickly replenish ink into an ink occluding body regardless of a capillary force of a pen tip. .

(Writing implement)
The writing implement 1 of the present invention is a writing implement 1 comprising at least a pen tip 2, an ink occlusion body 3 connected to the pen nib 2, and a barrel 4 accommodating the ink occlusion body 3 therein. It has an air hole 5 opened in front of the barrel 4 and communicating the inside and outside of the barrel 4, a front end opening 61 and a rear end opening 62, and the ink 9 is supplied to the ink storage body 3 from the outside. An ink supply path 6 that can be introduced is provided, and a front end opening 61 of the ink supply path 6 is positioned ahead of the front end 31 of the ink storage body 3, and a rear end opening 62 of the ink supply path 6 is provided. The ink storage unit 3 is connected to the ink storage unit 3 so as to be closed by the ink storage unit 3. The ink liquid surface 91 is positioned behind the front end opening 61 at the time of ink supply, and ink can be supplied from the ink supply path 6. (Claim 1) Further, the outer opening 51 of the air hole 5 and the front end opening 61 of the ink replenishment passage 6 are positioned forward of the front end 31 of the ink occluding body 3, and the capillary force of the ink replenishment passage 6 is reduced. It is set larger than the capillary force of the air hole 5, the ink level 91 is positioned behind the outer opening 51 and the front end opening 61 at the time of refilling the ink, and the ink can be replenished from the ink replenishing passage 6. Item 2) is a requirement.

  In the writing instrument 1 according to the first aspect, the pen point 2 facing downward is immersed in the refill ink 9 and the front end opening 61 is immersed in the refill ink 9. Using the capillary force and the capillary force of the ink occluding body 3, the ink 9 can be quickly sucked up and replenished in a short time.

  The “ink occluding body” is made of a fibrous processed body or a synthetic resin porous body and holds ink, and at the time of refilling ink, sucks the ink 9 from the outside by capillary force. As the fiber processed body, general-purpose ones such as a resin processed body of a fiber bundle, a heat fusion processed body of a fiber bundle, a resin processed body of felt, and a needle punched body of felt can be used. In addition, as the synthetic resin porous body, general-purpose ones such as polyolefin-based, polyurethane-based, and continuous porous bodies of various other synthetic resins can be used.

  The “air hole” is located in front of the barrel 4 and allows air to flow in and out when the volume inside the barrel 4 changes due to a decrease in ink or a change in temperature due to writing, and at the time of ink replenishment. Is a hole for easily discharging air inside the barrel 4 corresponding to the replenished ink amount to the outside of the barrel 4, and one or more holes are provided in front of the barrel 4.

  The “ink replenishment path” serves as an introduction portion for introducing the ink 9 into the ink occluding body 3 from the outside at the time of ink replenishment, and includes a rear end opening 62 abutting on a front portion of the ink occluding body 3, One or a plurality of front-end openings 61 are provided so as to be located forward (toward the pen tip 2) of the rear-end opening 62. By contacting the front end of the ink occluding body 3 so as to cover the rear end opening 62, the ink can be introduced by using the ink replenishing path 6 and the capillary force of the ink occluding body 3 at the time of ink replenishment. The used ink 9 can be immediately stored in the ink occluding body 3. The front end opening 61 is preferably provided in the vicinity of the pen tip 2 because it is more advantageous at the time of ink replenishment. The ink supply path 6 may be made of any material and shape as long as it is provided so that the capillary force is smaller than that of the ink storage body 3.

  As the "pen tip", any form such as a ball-point pen, a felt-tip pen, a marking pen, a fountain pen and the like can be used. Particularly, when a ball-point pen or the like which cannot replenish a sufficient amount of ink 9 from the pen tip 2 is used, the present invention is used. Is effective. In addition, when a pen tip 2 made of a fiber processed body or a synthetic resin porous body is used, the replenishment speed at the time of ink replenishment can be significantly improved.

  When refilling the writing implement 1 with the ink 9, the pen tip 2 is turned downward, and immersed in the refilling ink 9 from the pen tip 2 side to the rear of the front end opening 61 of the ink refilling path 6, thereby refilling the ink. The ink 9 is sucked into the writing instrument 1 by utilizing the capillary force of the passage 6 and the ink occluding body 3, and is held by the ink occluding body 3. At that time, the same amount of air in the barrel 4 as the volume of the ink 9 held is discharged to the outside through the air holes 5. In particular, when the pen tip 2 is made of a fiber processed body or a synthetic resin porous body, the ink 9 is replenished from the pen tip 2 together with the suction from the ink replenishment passage 6.

  The writing instrument 1 according to the second aspect refills the outer opening 51 and the front end opening 61 of the ink refilling path 6 having a stronger capillary force than the air hole 5 provided with the outer opening 51 in a state where the pen tip 2 faces downward. By being immersed in the ink 9, the ink 9 can be quickly and quickly replenished from the ink replenishment path 6 by utilizing the capillary force of the ink replenishment path 6 and the ink occluding body 3, and an axis corresponding to the ink replenishment amount. Since the air inside the cylinder 4 is released into the ink 9 to generate air bubbles, the state of replenishment can be visually confirmed.

  The air hole 5 is located forward of the front end of the ink occluding body 3. When the volume inside the barrel 4 changes due to a decrease in ink 9 due to writing or a change in temperature, the air flows in and out of the ink hole 5. At the time of replenishment, by setting the capillary force of the air hole 5 to be smaller than the capillary force of the ink replenishment path 6, the air inside the barrel 4 corresponding to the amount of ink replenished from the ink replenishment path 6 is removed. It is discharged into the external refill ink 9. When the ink 9 is replenished, bubbles are generated from the ink 9, but when the replenishment of the ink 9 is completed, the release of air from the air holes 5 is stopped, and the generation of bubbles is also stopped. The air hole 5 communicates with the outside through the outer opening 51 and communicates with the space inside the barrel 4 through the inner opening 52.

  The air hole 5 and the ink replenishment path 6 may have any shape as long as the capillary force of the ink replenishment path 6 is larger than that of the air hole 5.

  Further, when the writing implement 1 is applied to a toy or the like, the ink 9 can be used in place of a liquid such as water.
