Description

本発明は、インク等の塗布液を貯溜してそれをペン芯等に供給するマーカ等の塗布具に関する。 The present invention relates to an applicator such as a marker that stores a coating liquid such as ink and supplies it to a pen core or the like.

筆記具には様々なタイプがあるが、その一つとして後軸に収容したインク吸蔵体のインクをペン芯に供給するマーカタイプがあげられる。この種のマーカ、特にアルコール系のマーカは結露が発生しやすく、この結露に伴い、特に透明樹脂軸で軸筒内を視認可能とした筆記具の場合は、軸筒内が視認し辛くなるという問題点が発生する。 There are various types of writing instruments, one of which is a marker type that supplies ink from an ink occlusion body accommodated in the rear shaft to the pen core. This type of marker, especially alcohol-based markers, tends to cause condensation, and with this condensation, it is difficult to visually recognize the inside of the shaft tube, especially in the case of a writing instrument that allows the inside of the shaft tube to be viewed with a transparent resin shaft. A point is generated.

また、落下等によりインク吸蔵体のインクが飛散することを抑制防止するため、インク吸蔵体受けを備えた筆記具が提案されているが、インクの飛散により視認し辛くなる問題は防止できるが、結露により視認し辛くなる問題は解決できない（特許文献１参照）。 In addition, in order to prevent the ink on the ink occlusion body from scattering due to dropping or the like, a writing instrument having an ink occlusion body receiver has been proposed. The problem of difficulty in visual recognition cannot be solved (see Patent Document 1).

さらに、インク吸蔵体として中綿を使用する筆記具においては、ペン芯が設けられる先軸が透明な場合、結露が発生すると狭い隙間に結露した液滴が毛細管力で広げられて外観を損ねるという問題点があった。
特開平８−３９９８５号公報 Furthermore, in writing instruments that use batting as the ink occlusion body, when the tip shaft on which the pen core is provided is transparent, if condensation occurs, the condensed liquid droplets are spread in a narrow gap and the appearance is damaged. was there.

上述した従来の筆記具の問題点を解消するために、先軸より露出したペン芯付近を密閉するためのキャップにフェルトやスポンジを内蔵し、これらフェルトやスポンジによりペン芯からの揮発を抑制する技術が提案されている。 In order to solve the problems of the conventional writing instruments described above, a felt or sponge is built into the cap for sealing the vicinity of the pen core exposed from the tip, and the technology to suppress volatilization from the pen core by these felt or sponge Has been proposed.

しかしながら、結露の発生時間は遅くなるが、最終的には結露が発生するため上記問題は解決されない。 However, although the occurrence time of condensation is delayed, the above problem cannot be solved because condensation occurs in the end.

この問題の対策として、樹脂を肉厚に成形してキャップの内部温度の変化を抑制する方法が考えられるが、これではコスト削減を図ることができない。 As a countermeasure for this problem, a method of suppressing the change in the internal temperature of the cap by molding the resin thick is conceivable, but this cannot reduce the cost.

次に、本実施形態の塗布具１００における先軸３０と検知管４０との組付けについて図面を参照して詳細に説明する。 Next, the assembly of the front shaft 30 and the detection tube 40 in the applicator 100 of the present embodiment will be described in detail with reference to the drawings.

先軸３０と検知管４０とは、図２に示すように、先軸３０の先端部３１内において、先端部３１の内周面と検知管４０の取付部４１ｂ端部に形成された突起部４５との隙間が略０．１ｍｍとなるように形成され、先端部３１の内周面と検知管４０の外周面との間に少なくとも突起部４５の突出量分の隙間７０が形成された状態で組付けられる。
なお、先端部３１の内周面と突起部４５との隙間は、０．０５〜０．１５ｍｍの範囲が好ましく、０．０５ｍｍ以下では隙間が小さすぎて結露水を保持できず、０．１５ｍｍ以上では毛細管力が弱くなる。 As shown in FIG. 2, the front shaft 30 and the detection tube 40 are formed on the inner peripheral surface of the front end portion 31 and the end of the attachment portion 41 b of the detection tube 40 in the front end portion 31 of the front shaft 30. 45 is formed so that the gap with respect to 45 is approximately 0.1 mm, and a gap 70 is formed between the inner peripheral surface of the tip portion 31 and the outer peripheral surface of the detection tube 40 at least for the amount of protrusion of the protrusion 45. It is assembled with.
The gap between the inner peripheral surface of the tip 31 and the protrusion 45 is preferably in the range of 0.05 to 0.15 mm. If the gap is 0.05 mm or less, the gap is too small to hold dew condensation water, and 0.15 mm. As described above, the capillary force is weakened.

また、隙間７０は、結露した液滴が毛細管力により先端部３１の内周面と検知管４０の外周面との間に広がらない程度に形成され、例えば、本実施形態においては、先端部３１の内周面と検知管４０の外周面との隙間７０が略０．３ｍｍとなるように形成されている。この隙間７０は、０．２５〜０．３５ｍｍの範囲が好ましく、０．２５ｍｍ以下では結露により汚れが発生し易く、０．３５ｍｍ以上ではがたつきが生じ易くなる。 Further, the gap 70 is formed to such an extent that condensed liquid droplets do not spread between the inner peripheral surface of the distal end portion 31 and the outer peripheral surface of the detection tube 40 by capillary force. For example, in the present embodiment, the distal end portion 31 is formed. The gap 70 between the inner peripheral surface of the tube and the outer peripheral surface of the detection tube 40 is formed to be approximately 0.3 mm. The gap 70 is preferably in the range of 0.25 to 0.35 mm. If the gap is 0.25 mm or less, contamination is likely to occur due to condensation, and if it is 0.35 mm or more, shakiness tends to occur.

なお、この隙間７０の距離は、使用される塗布液の毛細管力により適宜に決定されるものであって、少なくとも結露した液滴が広がらない程度であれば充分であり、また、より多くとったものであっても良い。 Note that the distance of the gap 70 is appropriately determined depending on the capillary force of the coating liquid to be used, and at least it is sufficient that the condensed droplets do not spread, and more is taken. It may be a thing.

The spread of the condensed ink can be suppressed.

また、本実施形態によれば、上述したように検知管４０を構成したので、インクは、インク吸蔵体１０から中継芯５０、及び該検知管４０を経由してペン芯６０に浸透し、このペン芯６０により筆記が可能になる。 Further, according to the present embodiment, since the detection tube 40 is configured as described above, the ink permeates the pen core 60 from the ink occlusion body 10 via the relay core 50 and the detection tube 40, and this The pen core 60 enables writing.

さらに、検知管４０を透明な部材により形成したことで、長期に亘る筆記によりインクが減少して終了する場合には、検知管４０の検知空間４２に貯溜されたインクが無くなるので、インクの終了サインを視覚的に簡単に且つ明瞭に検知することができる。 Further, since the detection tube 40 is formed of a transparent member, when ink is reduced due to writing over a long period of time, the ink stored in the detection space 42 of the detection tube 40 disappears, so that the ink ends. Signs can be detected visually easily and clearly.

また、本実施形態では、インク吸蔵体受け２０に結露防止孔２１を設けたことで、該結露防止孔２１から結露水をインク吸蔵体受け２０の外面からインク吸蔵体受け２０の内部に導くことができるので、結露の発生を抑制することができる。したがって、例えば、アルコール系のマーカでも結露が発生し難く、結露に伴い筆記不良を招くのを有効に抑制防止することができる。 Further, in the present embodiment, the dew condensation prevention hole 21 is provided in the ink occlusion body receiver 20, so that dew condensation water is guided from the outer surface of the ink occlusion body receiver 20 to the inside of the ink occlusion body receiver 20.

It is possible to effectively prevent the detection tube 40 from dropping from the rear shaft 1.

尚、本実施形態では、ペン芯６０の検知管４０への組付けは、ペン芯６０側の溝部６３と検知管４０側の係止部４６とが係合することで位置決め固定するようにしているが、ペン芯６０の最大幅部６０ｃを検知管４０内にきつい嵌合で嵌入することで寸法安定性を増大させ、樹脂成分が多く硬度の高い領域でシールして、さらに強度を向上させることができる。これにより、筆記時のペン芯６０の横倒れを防いだり、安定したシール性を確保することが可能となり、さらには気泡の混入防止も期待できる。 In this embodiment, the pen core 60 is assembled to the detection tube 40 by positioning and fixing by engaging the groove portion 63 on the pen core 60 side and the locking portion 46 on the detection tube 40 side. However, the dimensional stability is increased by fitting the maximum width portion 60c of the pen core 60 into the detection tube 40 by tight fitting, and sealing is performed in a region having a large amount of resin components and high hardness, thereby further improving the strength. be able to. As a result, it is possible to prevent the pen core 60 from falling sideways at the time of writing, to ensure a stable sealing property, and to prevent the mixing of bubbles.

また、本実施形態では、後軸１については単に形状的な全体構成を示したが、特に問題がなければ、後軸１の一部を透明に形成したものであっても良い。さらに、先軸３０、検知管４０、中継芯５０、及びペン芯６０を一体構造に構成したものであっても良い。さらに、また、検知管４０に中継芯５０とペン芯６０とをそれぞれ圧入して構成したものであっても良いが、例えば三つ割れのいわゆるチャック構造等で構成することもできる。 Further, in the present embodiment, the rear shaft 1 is simply shown as a shape overall configuration, but if there is no particular problem, a part of the rear shaft 1 may be formed transparently. Furthermore, the front shaft 30, the detection tube 40, the relay core 50, and the pen core 60 may be configured as an integral structure. Furthermore, although the relay core 50 and the pen core 60 may be press-fitted into the detection tube 40, respectively, for example, a so-called chuck structure having three cracks may be used.

さらに、本実施形態では、検知管４０の先軸３０側の一端部につば状の突起部４５を構成して、先軸３０の内周面と検知管４０の外周面との間に所定の隙間７０を形成するようにしたが、本発明は、先軸と検知管の構成に限定されるものではなく、例えば、先軸３０の内周面に検知管４０に向かい突出する突起部を周面に沿って形成し、先軸３０の内周面と検知管４０の外周面との間に所定の隙間を形成するようにしたものであっても良い。 Further, in the present embodiment, a flange-like protrusion 45 is formed at one end of the detection tube 40 on the front shaft 30 side, and a predetermined interval is provided between the inner peripheral surface of the front shaft 30 and the outer peripheral surface of the detection tube 40. Although the gap 70 is formed, the present invention is not limited to the configuration of the tip shaft and the detection tube. For example, a protrusion projecting toward the detection tube 40 is provided on the inner peripheral surface of the tip shaft 30. A predetermined gap may be formed between the inner peripheral surface of the tip shaft 30 and the outer peripheral surface of the detection tube 40.

さらに、また、前記突起部４５の換わりに、例えば、先軸と検知管との間に別体で構成した所定の厚みを有するスペーサを介在させて、先軸と検知管との間にスペーサの厚さ分だけの隙間を形成するようにしたものであっても良い。このように構成することで、部品構成を簡単にでき、しかも、簡単に組付けることができる。 Furthermore, instead of the protrusion 45, for example, a spacer having a predetermined thickness formed separately between the front shaft and the detection tube is interposed, and the spacer is interposed between the front shaft and the detection tube.
