As shown in Figure 1, rear axle 1 for example uses the predetermined synthetic resin that is made of PP etc., and forming the top has peristome and long round-ended cylinder shape arranged, and it plays a role as the writing appliance main body.The part of the inner peripheral surface of this rear axle 1 is that about first half forms hole enlargement inner peripheral surface 2, and the remainder of inner peripheral surface to be about latter half form undergauge inner peripheral surface 3, between this hole enlargement inner peripheral surface 2 and undergauge inner peripheral surface 3, form angled step face 4 (with reference to Fig. 2).Consider that from outward appearance and practical angle rear axle 1 is configured as opaque or transparent.
The flow fluid body of attracting deposits is that ink is attracted deposits body 10 as shown in Figure 1, and it is elongated cylindrical to use predetermined material to form, and contains to be soaked with the water-soluble ink (with reference to the arrow among Fig. 1) that is made of water-base ink or oily ink.This middle cotton ink body 10 of attracting deposits can use fiber to form the bundle body, this fiber for example has: natural fiber, animal hair fibre, fibers such as polyacetals resin, acrylic resin, polyester resin, polyamide-based resin, polyurethanes resin, polyolefin resin, polyvinyl resin, PP resinoid, polyethers resin, polyphenylene resinoid, felt.In addition, can also select to use the porous body of sponge, resin particle, sintered body to form.
In order to allow the user detect the end of a period state of ink well, the surface tension of ink 25 ℃ be set at 18mN/m when following or more than, preferably 25 ℃ be set at 20～50mN/m when following or more than.The surface tension of this ink can be adjusted by following method, i.e. matching surface activating agent etc. in the composition of ink as required.
In order to ensure the smooth supply of ink to pen core 60, the viscosity coefficient of ink is set at 500mPas or following at 25 ℃ or when following, is preferably set to 200mPas or following, more preferably is set at 1～100mPas or following.This be because: when the viscosity coefficient of ink surpasses 500mPas, then can not guarantee the discharge of ink fully, and probably be accompanied by the deficiency of flow and cause the disappearance (ink starvation) etc. of stroke.The viscosity coefficient of this ink can be adjusted by following method, promptly cooperates thickener etc. as required in composition for ink.
As shown in Figure 1, the flow fluid body support of attracting deposits is that the ink body support 20 of attracting deposits for example uses the predetermined synthetic resin that is made of PP etc. and is configured as the convex shape of hollow.Such ink body support 20 of attracting deposits embeds from the peristome on the top of rear axle 1 by the gap that it is inner and contact with angled step face 4, is entrenched in ink attract deposits the tip side end of body 10 and contact with it.
As shown in Figure 1, front axle 30 for example uses the predetermined synthetic resin that is made of PP etc. and is configured as the convex shape of hollow transparent, light transmission rate is set at 30%～100%, be preferably set to 50%～100%, more preferably be set at more than 80%, it is installed in the peristome of rear axle 1, and is embedded into the attract deposits top ends of undergauge of body support 20 of ink.
The pen core protection uses the cap for brush 32 in detachable mode; be entrenched togather with the top ends 31 of front axle 30; front axle 30 is near the outer circumference surface the substantial middle portion; give prominence to that the circular orientation flange 33 that direction is stretched outside radius being set, this locating flange 33 is positioned the peristome end face of rear axle 1 and contact with it.On the inner peripheral surface circumferencial direction of top ends 31, optionally protrusion is being provided with the roughly ringwise pressure contact portion 34 that points to direction in the radius.
As shown in Figure 1, detector tube 40 uses predetermined material and is configured as the cylindrical shape with observability, and it traverses at ink and attracts deposits between the top ends 31 of the top ends of body support 20 and front axle 30 and be subjected to the attract deposits supporting of top ends 31 of the top ends of body support 20 and front axle 30 of ink.Material as this detector tube 40, can list: polypropylene, polyethylene, cyclic polyolefin, poly-polyolefin resins such as (1-methyl-4-amylene), and polystyrene, PETG, PEN, polybutylene terephthalate (PBT), fluororesin, silicon rubber etc.
On the inner peripheral surface of detector tube 40, implement the coating processing of fluororesin or silicones etc. selectively, handle by this, make the surface tension of the surface tension of detector tube 40 less than ink.On the outer circumference surface circumferencial direction of detector tube 40, cut out the portion that is crimped 41 of channel form, it is chimeric mutually and be crimped on pressure contact portion 34 that this is crimped portion 41.
As shown in Figure 1, relaying core 50 uses predetermined material and is configured as roughly cylindrical, embeds and be bearing in the ink ink of the detector tube 40 in the body support 20 end of body place that attracts deposits that attracts deposits.This relaying core 50 highlights and inserts the attract deposits top ends of body 10 of ink from the ink body support 20 of attracting deposits, and has by detector tube 40 to supply with the attract deposits function of ink of body 10 of inks to pen core 60.
Relaying core 50 can use fiber to form the bundle body, this fiber for example has: natural fiber, animal hair fibre, fibers such as polyacetals resin, acrylic resin, polyester resin, polyamide-based resin, polyurethanes resin, polyolefin resin, polyvinyl resin, polyethers resin, polyphenylene resinoid, felt.In addition, can also use the porous body of sponge, resin particle, sintered body to form.
The length of relaying core 50 can be set at ink attract deposits body 10 total lengths 5% or more than, be preferably 10% or more than, more preferably 20%～100%, more preferably 50%～100%.This be because: the length of relaying core 50 is lower than ink when attracting deposits body total length 5%, and probably the consumption rate of ink will reach the level identical with former middle cotton formula.
As shown in Figure 1, pen core 60 uses predetermined materials and forms the substantial cylindrical that the top is rounded, and embeds and be bearing in the attract deposits end of the opposite side of body of detector tube 40 and ink by O shape ring 61, and exposes from the top ends 31 of front axle 30.This pen core 60 can use fiber to form the bundle body, this fiber for example has: natural fiber, animal hair fibre, fibers such as polyacetals resin, acrylic resin, polyester resin, polyamide-based resin, polyurethanes resin, polyolefin resin, polyvinyl resin, polyethers resin, polyphenylene resinoid, felt.In addition, can also suitably use the porous body of sponge, resin particle, sintered body to form.
In said structure, ink is from the ink body 10 of attracting deposits, and via relaying core 50 and detector tube 40 and soak into pen core 60, becomes possibility by soaking into of this pen core 60 just made to write.Then, ink is reduced and when using up, because ink can be by the detection space 63 in the transparent detector tube 40, so from visually detecting the end of a period state of ink simply.
According to said structure, based on having or not of detection space 63 ink inside of detector tube 40, not relating to its shade just can be from visually accurately holding the end of a period state of ink.Therefore, even for example dry and when causing the disappearance of stroke, also can not detect the end of a period state of ink mistakenly at pen core 60, writing appliance is long-term to be used and improves convenience thereby also can make by it.
In addition, owing to detector tube 40, relaying core 50 and pen core 60 as other parts be assembled into integrative-structure realized integrated, thereby in detector tube 40, can not cause sneaking into of bubble and be easy to the assembling, thereby significantly improved assembleability and manufacturing etc.In addition, because pressure contact portion 34 and be crimped portion 41 and be fastened togather mutually tightly utilizes friction and inlay resultant force, can prevent coming off of front axle 30 or detector tube 40 etc. effectively.
Moreover, the Breadth Maximum part 62 of pen core 60 is embedded in the detector tubes 40 and size stability is increased, so seal, intensity is improved by and the high zone of hardness many at resinous principle.Thus, laterally the falling down of pen core 60 in the time of can preventing to write can guarantee stable sealing again, can also expect to prevent sneaking into of bubble.
Below, Fig. 4 represents the present invention's the 2nd embodiment, in this case, from the ink of the detector tube 40 outstanding flange 42 that is provided with of end, side direction outside radius of attracting deposits, this flange 42 is designed to and the ink opposed ink of top ends of the body 10 body support 20 of attracting deposits of attracting deposits.About other parts, because identical with above-mentioned embodiment, therefore, in this description will be omitted.
Even in the present embodiment, also can expect to have the action effect same, and the flange 42 of detector tube 40 plays a role as the ink body support 20 of attracting deposits, thereby can omit as the ink of other parts body support 20 of attracting deposits with above-mentioned embodiment.Therefore, it is self-explantory can significantly improving assembleability and manufacturing.In addition, form the ink blocking-up and use the next door, unnecessarily attract deposits between body 10 inflow front axles 30 and the detector tube 40 from ink so can effectively prevent ink owing to the flange 42 of detector tube 40 contacts with the inner peripheral surface of front axle 30.
Below, Fig. 5 represents the 3rd embodiment of the present invention, in this case, the top ends 31 of front axle 30 forms the undergauge tapering 35 that narrows down gradually, in exposing on the face of the pen core 60 that exposes from detector tube 40, otch and form mounting groove along the circumferential direction, the blocking device that comes off of the chimeric non junction ring-type limit collar 64 that promptly comes off on this mounting groove, and pen core 60 is highlighted from the undergauge tapering 35 of front axle 30, the limit collar 64 that comes off of pen core 60 is contacted with the inner face in the undergauge tapering of front axle 30.
Even in the present embodiment, also can expect the action effect identical with above-mentioned embodiment, and owing to make the limit collar 64 that comes off be fastened on the inner face in the undergauge tapering of front axle 30, therefore, utilize simple structure just can effectively prevent pen core 60 coming off from the detector tube 40, this is self-explantory.In addition, because the cylindrical portion that comprises flange 42 becomes the ink body and function retaining part of attracting deposits, so, do not pollute hand and can change the ink of the finishing using body 10 of attracting deposits.
Below, Fig. 6～Figure 11 represents the present invention's the 4th embodiment, and in this case, the ink body support 20 of attracting deposits forms roughly cylindrical shape, and this ink body support 20 of attracting deposits embeds in the rear axles 1, and is entrenched togather with the attract deposits end of body 10 of ink; On ink is attracted deposits the perisporium of body support 20, have dewfall and prevent hole 21, on ink is attracted deposits the perisporium of body support 20, be formed with fine convex-concave 22 simultaneously so that it produces capillarity.
As Fig. 6～shown in Figure 8, the ink body support 20 of attracting deposits for example uses the predetermined synthetic resin that is made of PP etc. and is configured as the cylindrical shape of hollow type, makes its inhibition and prevents splashing of ink thereby play a role.This ink body support 20 has an any number on its perisporium dewfall of attracting deposits prevents that hole 21 to reduce the volatilization ratio of pen core 60, forming fine convex-concave 22 respectively so that it produces capillary force at the upper edge, interior outside of perisporium direction of principal axis simultaneously.
Convex-concave 22 for example forms roughly V font (with reference to Figure 11) etc. of a plurality of section concave shapes (with reference to Fig. 9), section convex shape (with reference to Figure 10) or section at the attract deposits circumferencial direction of body support 20 of ink with predetermined spacing parallel arranging.Such ink body support 20 of attracting deposits embeds its inside from the peristome of rear axle 1, and is mutually opposed with the hole enlargement inner peripheral surface 2 of rear axle 1, contacts with angled step face 4 simultaneously, is entrenched togather and contacts with it with the attract deposits tip side end of body 10 of ink.About other parts, since identical with above-mentioned embodiment, its explanation omitted at this.

In addition, a plurality of convex-concaves 22 are under the effect of capillary force, make dew get back to ink attract deposits body 10 or pen core 60 by the attract deposits inside of body support 20 of ink from the attract deposits outside of body support 20 of ink, so write Shi Buhui blocking-up air displacement runner, can not cause the thin out of written handwriting because of producing dewfall.Owing to have such effect, thereby no longer to need ester moulding be heavy wall and suppress the variation of the cap for brush 32 internal temperatures with this, so can seek the reduction of cost.Moreover, because be not clamminess in the attract deposits outside of body 10 of ink when changing, thereby can reduce offending sensation.
Below, Figure 12 and Figure 13 represent the present invention's the 5th embodiment, in this case, except attract deposits body 10, ink of rear axle 1, ink attracted deposits body support 20, front axle 30, detector tube 40, relaying core 50 and the pen core 60, also make it have impact absorption mechanism 70, be applied to impact on the detector tube 40 etc. in order to absorption.
As shown in figure 13, impact absorption mechanism 70 is obliquely installed between the hole enlargement inner peripheral surface 2 and undergauge inner peripheral surface 3 of rear axle 1, be made of taper angled step face 71, wherein taper angled step face 71 contacts with the attract deposits open circumferential portion of body support 20 of the mode that can slide and ink.About other parts, since identical with above-mentioned embodiment, so omit its explanation at this.
Even in the present embodiment, also can expect the action effect same with above-mentioned embodiment, and when situations such as writing appliance drops take place, angled step face 71 direct ink of impact absorption mechanism 70 attract deposits body support 20 open circumferential portion and make its axially slide (reference arrow), therefore make to impact and relaxed, thereby can suppress and prevent sneaking into the fatal bubble of detector tube 40.
If be described in detail with regard to this point, then cause in detector tube 40 under the situation of bubble intrusion in percussion, irrelevant with the residual amount of ink, it is big that bubble becomes gradually, soon limit ink is led to the detection space 63 in the detector tube 40, thereby phonily shows the end of a period state of ink.Particularly when pen core 60 falls up, attract deposits ink in the body 10 of ink produces and flows, cause detector tube 40 to be had to go to the toilet and reduce sharply pressure, thereby detector tube 40 in very possible generation bubble.
In addition, angled step face 71 is not only to attract deposits body support 20 butts with ink and position and fix, but along with the effect of external force, angled step face 71 will make the ink body support 20 of attracting deposits slide, thereby can expect very much the attenuating that impacts.Therefore, suppress and prevent the intrusion of bubble, can prevent very effectively that the falseness of ink end of a period state from showing.
Below, Figure 14 represents the 6th embodiment of the present invention, in this case, the formation of impact absorption mechanism 70 is comprised: will make a distinction formed flat step face 72 between the hole enlargement inner peripheral surface 2 of rear axle 1 and the undergauge inner peripheral surface 3, and embed attract deposits elastic buffer body 73 between the open circumferential portion of body support 20 of this cascaded surface 72 and ink.
As buffer body 73, for example can list single or multiple O shape rings, non junction ring-shaped rubber, elastomer, sponge etc.About other parts, since identical with above-mentioned embodiment, so omit its explanation at this.
Even in the present embodiment, also can expect the action effect same with above-mentioned embodiment, in fact, the situation that does not adopt above-mentioned the 5th embodiment also is favourable.
Below, if describe with regard to the 7th embodiment of the present invention, then in this case, the material part of rear axle 1 is designed to elastomeric material and makes it have flexible or elasticity, just can make rear axle 1 itself become impact absorption mechanism 70 without accompanying drawing.
