Definitions
- the present invention provides a raw ink tank for accommodating a liquid material (hereinafter referred to as an ink) such as a water-based or oil-based ink for writing instruments, an ink for ink jet printer, a cosmetic liquid such as an eyeliner, and a coating liquid such as a paint or a chemical.
- an ink such as a water-based or oil-based ink for writing instruments, an ink for ink jet printer, a cosmetic liquid such as an eyeliner, and a coating liquid such as a paint or a chemical.
- the present invention relates to an applicator provided with a mechanism for automatically controlling ink ejection in response to application, writing, or recording. Background technology
- an ink storage unit is provided in the barrel, and the stored ink is sequentially replenished to the application body (pen body) as it is consumed in writing or application, so that writing or application can be performed continuously.
- a writing instrument for automatic discharge control of raw ink is known.
- an ink absorber is disposed in an ink circulation path between an ink storage section in a shaft and the tip of an application body, and the inside of a capillary of the application body corresponding to writing is arranged. It describes a raw ink discharge control mechanism that allows ink to flow and continuous writing by using the ink moving pressure (capillary osmotic pressure).
- the ink absorber is used because when the ink overflows from the raw ink storage section, it absorbs the ink and does not drop down from the application body section etc.
- the main purpose is to control in such a way.
- this type of ink absorber is generally used by arranging an ink absorber having a hollow cross section (a donut shape) in parallel or in series with the ink flow passage from the ink container to the application body.
- an ink absorber having a hollow cross section (a donut shape) in parallel or in series with the ink flow passage from the ink container to the application body.
- it is often used in a structure in which the ink absorber is contacted from above the ink flow passage to below, or only the upper part is contacted.
- the longitudinal dimension of the ink flow path from the ink storage section to the tip of the application body is compared with the longitudinal dimension of the ink absorber, the distance of the ink flow path is long.
- the longitudinal dimension must be increased, and for that purpose, the length of the ink flow path must be increased accordingly.
- the ink flow passage portion having a small diameter becomes longer, the viscosity resistance of the ink passing therethrough increases, so that the flow of the ink supplied from the ink storage section to the application body becomes slower. There are easy problems. If the diameter of the ink flow path is increased for the purpose of improvement, the mounting area of the ink absorber in the shaft inner diameter and the cross section is reduced, and the ink absorption capacity is relatively reduced.
- the disadvantage is that the cross-sectional shape of the ink becomes difficult to manufacture, etc.In order to increase the volume of the ink absorber or to manufacture an applicator with a large amount of ink using an applicator containing raw ink with a fixed thickness, There were many difficulties in the construction of the ink absorber. Furthermore, the structure using such an ink absorber has not yet been sufficiently effective in preventing falling off, and many problems have been recognized.
- the ink absorber is installed in contact with the ink in the ink flow path, so it naturally absorbs the ink in the ink storage section even under normal storage conditions, and is likely to be filled to near the saturated amount. .
- gas expansion occurs in the shaft due to environmental changes, and when ink is pushed out from the ink storage unit, the ink absorber lacks the ability to absorb the overflowing ink, causing dropping.
- the present invention has been developed to prevent ink leakage such as dropping of ink during storage and various use environment conditions even when using oil-based ink as well as water-based ink.
- An object of the present invention is to provide an applicator having a quality that can maintain appropriate ink ejection even at a high writing speed.
- the ink in the ink container may be temporarily supplied to the application body (pen body), causing a problem that the ink may be blurred. It is intended to solve the problem at the same time.
- the present invention has a raw ink storage section in which the filled ink can flow inside, an ink absorber for controlling the excessive outflow of the ink in the ink storage section, and a coating body for applying the ink.
- the ink flow path for guiding the ink in the ink storage section is divided into an ink flow path on the application body side and an ink ejection type flow path on the ink absorber side.
- An applicator circulation pipe whose inside is the applicator ink flow path is located below the ink connection port, which is the outlet of the ink flow path in the ink storage section.
- a double pipe consisting of an outer pipe for air circulation and an inner pipe, an ink absorber is disposed therein, and an air intake / exhaust air gap is formed.
- the opening inside shall have an opening shape in which the opening area is reduced from the outer peripheral side to the inner peripheral side of the axial cross section, or an uneven portion that forms a wide gap and a narrow gap is provided on the inner wall of the opening.
- a portion where the capillary action is strong and a portion where the capillary action is weak are formed in the opening.
- the ink absorption in the large-diameter portion of the inner pipe which is the rear portion of the flow passage on the side of the ink absorber.
- the body density (or capillary force) is A
- the density (or capillary force) of the capillary member arranged in the inner pipe small diameter portion at the front of the ink absorber side flow passage is B
- the coating material distribution is the ink passage on the coating material side.
- Density of capillary member placed in pipe Or capillary forces) and by C The gist of the applicator that has the relationship A, B, and C.
- the applicator according to the present invention provides: (1) an ink absorber that naturally absorbs ink in an ink storage unit to prevent a phenomenon of reaching a saturated absorption state; and (2) a change in expansion and contraction in the ink storage unit.
- the object described above has been achieved by enabling the function of returning the ink once absorbed by the ink absorber to the inside of the ink container to be repeatedly obtained. That is, the operation of the applicator according to the present invention is as follows.
- the ink absorber of the present invention (ink absorber side flow passage) is used for the ink absorber through the ink connection port when ink overflows. Since the ink is absorbed from the lower side to the upper side, the above-mentioned preferable function is obtained.
- the main reasons are as follows.
- the applicator circulation pipe portion serving as the applicator-side ink flow path is provided on the front side where the ink absorber does not exist in the same cross section. Therefore, the formation of the ink flow path leading to the tip of the application body is not affected by the ink absorber, and it is possible to make the flow path short and thick, and the ink in the ink storage section reaches the tip of the application body. The resistance is small and the discharge amount can be increased.
- the structure of the applicator according to the present invention has a structure in which the inner pipe above the ink connection port is used as an ink absorber-side ink flow passage, and an ink absorber is arranged inside the ink pipe, and a suction / exhaust air gap is formed therein. Therefore, when the ink overflows, the air in the ink absorber is easily discharged so that the ink can quickly penetrate and be absorbed into the ink absorber. As a result, when the expansion and overflow in the ink storage section is completed and the gas contracts again to change to a decompressed state, the ink absorber returns the overflow ink once absorbed to the ink storage section via the ink connection port again. The effect of facilitation can be improved.
- the ink absorber is arranged above the ink connection port.
- the ink absorbed by the ink absorber tends to collect at the lower ink connection port due to its own weight.
- the phenomenon that the ink is sucked into the ink storage section is reduced, and a state in which the ink is sucked back into the ink storage section with high efficiency is created.
- the overflowing ink branches out to the ink absorber side and the applicator side, and is absorbed by the ink absorber side when the inside of the ink container is significantly expanded.
- the overflowed ink that has not been removed overflows, and finally merges with the tip of the coating body via the bypassed ventilation gap, through the space around the coating body side.
- the outside air port that connects the inside and outside of the applicator is formed only on the periphery of the applicator body at the tip of the front shaft.
- the flow of ink and air can be stopped easily, and even if the overflowed ink accumulates on the peripheral side of the application body, the ink accumulates when the expansion of the ink accumulates and the pressure drops, and the ink accumulates An effect is obtained in which the ink is sucked back into the ink storage section through the application body.
- the structure of the applicator according to the present invention can achieve the above-described preferable effects, but the ink absorber absorbs and fills the ink in the ink storage section in a long-term natural environment.
- the density (or capillary force) of the ink absorber in the large diameter portion of the inner tube, which is located at the rear of the ink absorber side flow path, is A, and the ink flow path is not sufficient.
- B The density (or capillary force) of the capillary member arranged in the small diameter portion of the inner tube, which is the portion, is B
- a configuration was adopted in which the relationship of A ⁇ B and C was satisfied.
- the reason that the ink absorber is in a state of spontaneously absorbing the ink in the ink storage unit connected through the connection port is that external air corresponding to the ink absorption amount is sucked into the ink storage unit (air exchange is performed). Conversely), the air movement is suppressed, and the ink is applied to the entire ink absorber.
- air exchange is performed.
- the blocking action of air suction due to such a liquid-tight state is linked to the fact that the coating material with stronger capillary action consumes ink and the ink is absorbed and transferred to the coating material of density C, and the pressure inside the ink storage unit is reduced. By doing so, the outside air can pass through, so that continuous writing is possible.
- the ink absorber can maintain the unabsorbed state in which the ink can be absorbed for a long period of time, and can prepare for irregular ink overflow under various use environment conditions during storage and use. .
- the overflowing ink is applied to the application body through the ink connection port.
- the ink flows in both directions of the ink flow path and the ink absorber side flow path.
- the ink flow path on the application body has the highest density (C), so that the resistance to the passage of ink is large and it is difficult to flow out.

- the ink connection port 3h is a through-opening that radially connects the outer peripheral portion of the outer tube 3c and the inner tube 3d by a partition wall 3j that blocks a part of the cross section of the ventilation gap 3e.
- the raw ink in contact with the outer tube 3 does not contact the ventilation gap 3 e but communicates with the inside of the inner tube 3 d by the ink connection port 3 h opening.

- the present embodiment having such a structure has the following functions and actions.
- the raw ink filled in the rear shaft 1 flows and flows through the ink flow path 2d, and the rear part 4a of the coated body pressed and fixed to the coated body flow pipe 3b through the ink connection port 3h opening, and It is placed in the front small diameter portion 3 d 1 of the inner pipe 3 d and is in contact with the compressed ink absorber compression portion 6 a which has been compressed. For this reason, ink can be supplied directly from the ink connection port 3 h to the tip of the coating body 4, and the thick coating body rear part 4 a is also attached, so that ink ejection is good. You.
- the air existing inside the ink absorber 6 bypasses the air intake / exhaust gap 3 g on the outer periphery, communicates with the air gap 3 e, and is further connected to the front shaft through the air gap 3 f, and the outside air port 2 c Since the air is ventilated to the outside air, the air can be smoothly sucked and exhausted, and the ink absorber 6 has good ink absorption and capture properties.
- the ink absorber 6 naturally absorbs the ink from the ink connection port 3 h, the ink is filled in the ink absorber 6, but in this embodiment, the ink absorber 6 is The density is high (B) due to compression at the small diameter section 3d1 at the front of the pipe, and relatively low (A) because the rear area is not compressed. A strong capillary force acts locally to penetrate and fill the ink, but the lower part of the lower density is in a state where the ink is difficult to penetrate.
- the ink absorber 6 tries to absorb the ink in contact with the ink connection port 3h, in order to suck out the ink in the ink storage section 1a, the same amount of external air as the amount of ink to be absorbed is required.
- the ink cannot be absorbed unless it is sucked into the ink container 1a. That is, the inside of the small-diameter portion 3 d 1 absorbs ink with strong capillary force (B), and the ink absorber 6 in the large-diameter portion 3 d 2 in the state of relatively low capillary force (A) is applied.
- the capillary force (C) at the rear part 4a of the applied body is more strongly related to the capillary force (B) at the ink absorber part compressed inside the small diameter part 3d1, so that the coating is applied.
- ink is supplied smoothly from the ink connection port 3h. Since the pressure inside the ink storage section 1a is reduced in response to this ink consumption, external air is sucked into the small diameter section 3d1 through the suction / exhaust gap 3g, enabling continuous writing with automatic control. It becomes. As writing progresses, ink is consumed, the amount of external air sucked into the ink storage section 1a increases, and at this time, when a temperature change or the like occurs, the amount of gas expansion physically increases.
- the ink is pushed out by the gas expansion in the ink storage section 1a.
- the ink spills out to both the ink absorber side (small diameter part of the inner tube) and the coating body side (in the coating body flow pipe) through the ink connection port 3h opening.
- the ink passage resistance is large.
- the absorber side there are many unabsorbed capillaries in the large-diameter section 3d2 and the air discharge is good, so the passage resistance is lower than that of the coated body side.
- the absorber quickly absorbs the ink, and can prevent the ink from dripping from the application side with good functionality.
- the flow path on the application body side has a strong capillary action, so that external air hardly passes through this ink flow path, while ink is absorbed. Since the body-side flow passage has relatively weak capillary action, the ink absorbed in the ink absorber collects in the inner tube small-diameter portion 3d1 and passes through the ink connection port 3h opening to the ink storage section. Since it is sucked and returned to 1a, the unabsorbed capillary portion increases again in the ink absorber 6, and it is possible to prepare for the next expansion. That is, it has a favorable effect as a structure of the applicator that can cope with continuous expansion and contraction.
- the ink can not be absorbed by the ink absorber 6 such as when the gas expansion of the ink storage portion is extreme, the ink overflows and flows out to the coating body 4 in the front shaft 2. Since the passage to the outside is provided only on the peripheral side of the application body, it is possible to prevent falling off by ordinary means such as sealing only the outer peripheral part of the front shaft with a cap.
- Example 2 Even when the ink temporarily accumulates in the front shaft 2, the ink that has come into contact with the applicator 4 will lose the ink from the applicator 4 when the gas in the ink container 1a contracts and the pressure is reduced.
- the ink flow passage is easy to suck, so it is highly reliable in preventing ink drop, has good ink ejection, and is easy to install a large ink absorber even when filling a large volume of ink.
- An extremely preferable applicator can be provided. Example 2
