Above, complete the explanation to the assembling structure of the applicator 1 of present embodiment.

Describe below, and then with reference to the effect of the applicator 1 of Fig. 8,9 pairs of present embodiments.

When making nib 6 towards downside in order to write, as shown in Figure 8 (a), ink 7 due to gravity from the inner space 45 of ink tank portion 5 to cotton configuration section 8 side shiftings.Now, ink 7 moves to the below part of the inner space 20 of relaying core 3 by providing ink hole 49.And, move near ink 7 lower end of protuberance 11 because self gravity and middle cotton 4 capillary force is drawn towards lower side.Thus, ink 7 is emitted from intercommunicating pore 13, is supplied to middle cotton configuration section 8.That is, the inner space 20 of relaying core 3 become supply with ink 7 time ink flow path.

At this, in the present embodiment, utilize pressing tablet 33 from press top cotton 4.Thus, part is formed with that voidage relatively reduces below middle cotton 4 middle density portion 53.That is, utilize pressing tablet 33 grades cotton 4 from press top, middle cotton 4 the part being pressed is depressed into below and gathers.Thus, in middle cotton 4, part is formed with voidage compared with low-density high and that fibre density is lower portion 54 up, below part be formed with voidage compared with low and fibre density is higher middle density portion 53.And nib 6 becomes with middle cotton 4 middle density portion 53 compares the high density portion that fibre density is higher.

That is, in the present embodiment, middle cotton 4 upper section with below part be formed with the part that continuous fibre density is different, fibre density uprises along with going downwards.And therefrom cotton 4 rear end is gone to the front end of nib 6, low-density portion 54, middle density portion 53, high density portion (nib 6) are continuous.In addition, in the present embodiment, as shown in Figure 8 (a), therefrom cotton 4 front end is to becoming middle density portion 53 near the lower end of pressing tablet, and the part at rear becomes low-density portion 54 near the lower end of pressing tablet 33.

Thus, ink 7 stably can be supplied to nib 6.For example, even if ink 7 for the gravity that only utilizes self can not arrive the ink of the opening of intercommunicating pore 13, also can make ink 7 cotton 4 from relaying core 3 sucks, and therefrom cotton 4 to nib 6, move.

Now, ambient atmosphere (air of trace) is imported the inner space 45 of ink tank portion 5 from intercommunicating pore 13.And, in inner space 45, carrying out the exchange of ink 7 and ambient atmosphere, ink 7 is by cotton configuration section 8 from intercommunicating pore 13 is promptly supplied to.

That is, the applicator 1 of present embodiment imports ambient atmosphere from intercommunicating pore 13, and emits ink 7 from intercommunicating pore 13.That is, the relaying core 3 of present embodiment becomes following structure: only have a protuberance 11 as communicating pipe, only the protuberance 11 of doubles as pipe and ink release pipe for ambient atmosphere importing.And, become and in this protuberance 11, implement the importing of ambient atmosphere and the structure of emitting of ink simultaneously.In addition, by the size of the diameter of intercommunicating pore 13, area being made as to the size of above-mentioned expectation, the flow velocity of ink 7 can be made as to preferred speed.Thus, can make the supply of ink 7 of the cotton configuration section 8 of centering more stable.

At this, for relaying core 3, possess in the present embodiment the structure of pressing tablet 33, as mentioned above, becoming can be by the structure of ink 7 cotton 4 from relaying core 3 strongly sucks.Therefore, in the present embodiment, even for only to have the structure of the structure of a protuberance 11, also can stably supply with ink 7.That is, in the present embodiment, even if plural protuberance is not set, or the protuberance that diameter is larger is not set, also become utilization only the protuberance 11 of just can fully supply with the structure of ink 7.Thus, in the present embodiment, plural protuberance need not be set, or form the larger protuberance of diameter, have advantages of that the free degree of design of relaying core 3 is higher.

And, the state by from shown in Fig. 8 (a) continue to cotton configuration section 8 supply with inks 7, thereby as shown in Figure 8 (b) shows, ink 7 infiltrates in middle cotton 4.In addition, now, because intercommunicating pore 13 contacts with middle cotton 4, therefore, the capillary force that arrives cotton 4 near the ink of intercommunicating pore 13 7 quilts attracts.Therefore, near intercommunicating pore 13, flowing not of ink 7 can be stagnated due to the surface tension of ink 7 etc.

And, when ink 7 infiltrates in middle cotton 4 time, the water level of the ink 7 of middle cotton configuration section 8 rise (boundary line of water level is close to ink tank portion 5 sides).As shown in Fig. 8 (c), the water level of the ink 7 of the middle cotton configuration section 8 of rising, finally arrives the height (position) of intercommunicating pore 13.

Like this, after the water level of the ink 7 of middle cotton configuration section 8 rises, as shown in Fig. 8 (c), ink 7 is filled to the position of intercommunicating pore 13.Thus, intercommunicating pore 13 passes through that infiltrated ink 7 becomes liquid sealing state and in fact by obturation.And, can not import ambient atmosphere to the inner space 45 of ink tank portion 5, the supply of the ink 7 of the cotton configuration section 8 of centering stops.Now, middle cotton 4 front side (downside in Fig. 8,9) becomes the state fully infiltrating in ink 7, and rear side (upside in Fig. 8,9) becomes the state not infiltrating in ink 7.In addition, conventionally, in this, cotton 4 rear side does not infiltrate in ink 7, but except the situation that the posture of the situation that temperature around rises and applicator 1 tilts etc.

And, while continuing to write under middle cotton 4 the front side infiltration as Fig. 9 (a) has the state of ink 7, infiltrating and will reduce soon in middle cotton 4 ink 7, the liquid sealing state of intercommunicating pore 13 is disengaged.Then, as shown in Figure 9 (b), ambient atmosphere is absorbed in ink tank 3 again, therefore, starts the cotton configuration section 8 of centering and supplies with ink 7.And, as Fig. 9 (c), continue to supply with ink 7 to middle cotton configuration section 8, until intercommunicating pore 13 is owing to again being become liquid sealing state by the ink that is infiltrated 7.Like this, whenever ink 7 is owing to writing while reducing, can supply with inks 7 to middle cotton configuration section 8 and middle cotton 4.And, be supplied to middle cotton 4 the ink 7 therefrom density portion 53 that is difficult to and flow to low-density portion 54.That is, owing to being supplied to middle cotton 4 ink 7, easily flow to nib 6 sides, therefore, ink 7 stably can be supplied to nib 6.

In the above-described embodiment, the example that is marker pen exemplified with applicator 1, but the present invention is not limited thereto.The present invention also can be the applicators such as pen, ball pen, opaquing fluid.Therefore, the raw material of main body cylinder 2 and shape can suitably change.

In addition, nib 6 also can melt that processome, felt processome, tubulose handwriting, front end have the tabular handwriting of pen type, the writing brush handwriting of slit, porous air bladder, the ball-point pen tip of synthetic resin, the extruded body etc. with the synthetic resin of axial ink path of navigation form by the process of resin body of fibre bundle, the heat of fibre bundle, and the raw material of fore-end and opening shape can suitably change.

And then as long as middle cotton 4 for having as described above the member of the continuous pore of the ink 7 that can infiltrate, its shape is also not limited to substantial cylindrical shape, rectangular shape roughly.Raw material and shape can suitably change.

In addition, in the above-described first embodiment, though the protuberance main body 32 of relaying core 3 is illustrated with middle cotton 4 modes that contact, relaying core 3 can not contact with middle cotton 4 yet.But, if the intercommunicating pore of relaying core 3() do not contact with middle cotton 4, in the situation that the less surface tension that acts on ink 7 of the internal diameter of relaying core 3 surpasses gravity, ink 7 is trapped in hollow space 21, therefore, when supplying with ink 7 to middle cotton configuration section 8, the discharge of the unit interval of ink 7 reduces sometimes.On the other hand, when relaying core 3 is when middle cotton 4 contact, in utilization, cotton 4 capillary force attracts ink 7, and ink 7 is flowed sleekly, therefore, even the internal diameter of relaying core 3 is designed littlely, also can make the discharge of unit interval of ink 7 stable.Therefore, like this, be preferably relaying core 3 and contact with middle cotton 4.

In addition, in the above-described first embodiment, though be configured to middle cotton 4 opening whole that cover intercommunicating pores 13, be not limited to this.The opening of intercommunicating pore 13 also can be covered by middle cotton 4, can also for the part of the opening of intercommunicating pore 13 only by cotton 4 structures that cover.But, when being configured to middle cotton 4 while covering opening whole of intercommunicating pores 13, near the ink 7 being arranged in the front end of protuberance 11 can be drawn to cotton 4 side draughts more reliably, therefore preferably.

And in the above-described first embodiment, pressing tablet 33 is tabular, and be the structure contacting with the side of protuberance main body 32 and the front end face 25 of base portion 12, but relaying core of the present invention is not limited thereto.For example, the second embodiment that also can be as shown in figure 10, adopts to possess not contact with protuberance main body 32 and from the base portion 12 relaying core 60 of outstanding pressing tablet 61 forwards.

In addition, the 3rd embodiment that also can be as shown in figure 11, adopts pressing tablet 71 contact with base portion 12 and from the relaying core 70 of protuberance main body 32 crooked extensions.

In addition, the shape of pressing tablet of the present invention is not particularly limited, and can be the pressing tablet (with reference to Figure 10) of the pole shape shown in the second embodiment yet, can be the pressing tablet (with reference to Figure 11) of hook-shaped (the L letter stencil shape) shown in the 3rd embodiment yet.Therefore, pressing tablet can be cross sectional shape for the pressing tablet extending as quadrangle polygon-shapedly, also can be the pressing tablet of cross sectional shape for extending circularly.In addition, also can be the crooked pressing tablet extending of a part.

That is, as long as pressing tablet of the present invention can be by pressing middle cotton, and make to be arranged near at least a portion of the cotton ink discharge outlet (intercommunicating pore 13) of relaying core or all become the state that fibre density is higher.

The pressing tablet of the respective embodiments described above is all provided with two at relaying core, but the quantity of pressing tablet can be one, also can be more than three.

In the respective embodiments described above, though the angle that be take in the protuberance of relaying core and the upper surface of middle cotton to be become contacts as the modes of 90 degree roughly, but the arrangement angles of relaying core is not limited thereto, the Suo Cheng angle, upper surface of the protuberance of relaying core and middle cotton is not particularly limited, but be preferably to become the following mode of above 90 degree of 70 degree, the protuberance of relaying core and the upper surface of middle cotton is contacted.

The ink that used is in the respective embodiments described above not particularly limited, but can suitably use, to have ratio of viscosities 6.7mPas large, and the contact angle while contacting with the surface of solids is less than 53.8 degree, the ink of the characteristic that surface tension is less than 33.5mN/m in addition.
