- writing instrument a through hole through which a relay core is inserted is formed in a partition wall that separates a reservoir chamber and an ink storage chamber, and ink is introduced between the inner wall of the through hole and the relay core by capillary force. A predetermined gap is formed so as to be held, and gas-liquid exchange is performed at this portion.
- the ink stored in the ink storage chamber acts as a gas-liquid exchange in the gap between the inner wall of the through hole and the relay core (enables air to flow into the ink storage chamber), so that the ink is stored on the coating body side. Consumed (written).
- air enters the ink storage chamber through the gap portion by the amount of the consumption.
- the internal pressure in the ink storage chamber increases due to a temperature change or the like, the ink is likely to be pushed out into the reservoir chamber through the through hole.
- the amount of expansion of air becomes the amount of ink extruded as it is, so that the ink is easily extruded and a large amount of ink flows out into the reservoir chamber.
- Patent Document 1 discloses that an occlusion body for storing extruded ink is provided in the reservoir chamber, but it is preferable to prevent the ink from being extruded into the reservoir chamber as much as possible.
- Patent Document 2 discloses a structure that limits the amount of ink that enters the gas-liquid exchange region from the ink storage chamber so that a large amount of ink is not pushed out into the reservoir chamber. That is, a partition wall extending portion extending toward the ink storage chamber is formed in the partition wall in which the through hole is formed so that the relay core can be inserted as it is, and between the inner surface of the partition wall extending portion and the outer peripheral surface of the relay core. Ink can be held in the gap along the axial direction by capillary force.
- an air inlet through which air can flow is opened in a storage chamber for storing ink, and the ink stored in the storage chamber is consumed at this air inlet. It functions to allow air to flow in as much as it is.
- Such an air inlet is composed of, for example, a through hole through which a relay core is inserted through a partition wall separating a storage chamber and a reservoir chamber with a predetermined gap, as disclosed in the above-mentioned patent document. Is possible.
- the ink can flow out smoothly by separately forming an air inlet that communicates with the atmosphere in the storage chamber, but in such a configuration, when the internal pressure of the storage chamber increases, the ink is applied as it is. It flows into the body and puts the coated body in an ink-rich state. Even in a configuration in which a gap is formed in the through hole of the partition wall and a relay core is inserted through this portion to exchange gas and liquid, the ink contained in the storage chamber is the ink held in the through hole portion of the partition wall. It is in a state of being connected to.
- the ink in the storage chamber also flows to the coating body side as it is, and the coating body side is likely to be in an ink-rich state. That is, it is difficult to control the supply of ink to the coating body side with the conventional raw ink type coating tool.
- An object of the present invention is to provide a coating tool that controls the liquid supplied from the storage chamber to the coating body side and can obtain a smooth coating action.

Since the storage chamber is in a state of communicating with the atmosphere through the air port of the air communication pipe, if the air communication pipe is separated from the partition wall, the partition wall will not be affected by temperature rise or change in atmospheric pressure. The liquid immediately flows into the flow path and moves to the coated body. In this case, even if the liquid has a high viscosity, the storage chamber is in the same state as the atmospheric pressure through the air port of the air communication pipe, so that a stable liquid outflow state can be obtained. Further, since the air communication pipe is urged to the partition wall side by the urging means, when the vibration to the main body is stopped, the air communication pipe blocks the flow path and prevents the liquid from flowing out.

- a reservoir chamber 30 for storing the liquid flowing out from the flow path 10a may be formed on the coating body side with respect to the partition wall 10.
- the reservoir chamber 30 shown in the figure is formed by forming a recess 7a in the coating body 7, and is also formed between the partition wall 10 and the coating body 7 by shortening the coating body 7. It is also possible. By forming such a reservoir chamber 30, even if the main body 3 is shaken too much and a large amount of liquid flows out from the flow path 10a, such excess liquid can be stored.

Abstract
Description
すなわち、従来の生インク式の塗布具では、塗布体側へのインクの供給を制御することが難しい。
本実施の形態の塗布具1は、空洞部を有する円筒状の軸筒(本体)3を備えている。前記本体3内には、液体100が収容される貯留室5と、液体100を塗布する塗布体(筆)7が設けられており、本体3の内部に圧入固定される隔壁10によって、本体3は、貯留室5側と、塗布体7側に区分けされている。
この場合、塗布体7は、隔壁10に対して、直接、接触するように保持されていても良い。すなわち、塗布体7は、隔壁10に対してシールするように接触(密着)するような構成であっても良い。或いは、塗布体7と隔壁10は、部分的に接触するような構成であっても良い。
なお、塗布体7と隔壁10は、上記したように密着(部分的な密着を含む)していても、空気の流通を確保することは可能である。
なお、図1に示すように、ホルダ8に小径部8bを形成し、この部分に塗布体7を固定することで、塗布体7とホルダ8の内面との間の環状の隙間8cを空気通路とすることも可能である。
また、空気連通パイプ15の断面形状については、円形以外にも、多角形状にする等、特に限定されることはなく、更には、部分的に中実に構成されていても良い。例えば、後端側を中実状にして、重量部としての機能を持たせても良い。また、空気連通パイプ15の構成(太さ、長さ、素材など)については、充填される液体の態様(粘度、用途等)に応じて適宜、設定される。
なお、前記空気連通パイプ15は、隔壁に流路以外の空気孔を形成する等、流路10a以外の経路で大気と連通する構成であっても良い。
この規制部は、例えば、隔壁10の軸方向肉厚を多少厚く形成しておき、この部分に、空気連通パイプ15の先端が入り込む凹所(規制部)10cを形成することで構成することが可能である。凹所10cは、空気連通パイプ15がある程度の遊度をもって軸方向に移動できる程度に形成されていれば良く、空気連通パイプ15が隔壁10側に付勢されている状態で、空気連通パイプ15の外周面と凹所10cの内周面との間に液体が保持される程度の微小隙間が形成されていれば良い。或いは、空気連通パイプ15が変位して、隔壁から離間した際に液体を流路10a内に案内可能であれば、空気連通パイプ15の外周面と凹所10cの内周面との間で液体を保持しない程度の嵌合状態であっても良い。また、そのような凹所10cの軸方向長さについては、空気連通パイプ15を安定して規制できるように、空気連通パイプ15の移動ストローク量(付勢手段の付勢力によって調整される)Wよりも長く形成することが好ましい(図1では、略同じに形成されている)。
なお、空気連通パイプ15の径が細い、空気口15Aが小径、貯留する液体の粘性が高い等であれば、空気連通パイプ15内に流出する液体も非常に少量であり、また、空気連通パイプ15内に流出した液体は、そのまま流路10aを介して塗布体7に入り込むことができるため、空気口15Aの形成位置については、収容する液体や空気連通パイプ15の径等に応じて適宜変形することが可能である。
以下に説明する実施形態では、図1に示す実施形態と同様な構成部分については、同一の参照符号を付し、詳細な説明については省略する。
この実施形態では、空気連通パイプ15の円周壁15aに空気口を形成することなく、後端の開口部15Bに圧入される撹拌部材22に、貯留室に開口する開口部(空気口)を形成している。すなわち、空気連通パイプ15の開口部15Bに圧入される撹拌部材22の後端に空気口22bを形成すると共に、撹拌部材22に、軸方向に貫通する貫通孔22cを形成しておき、空気連通パイプ15内の空気を、撹拌部材22の貫通孔22c及び空気口22bを介して、空気を貯留室5内に排気するようにしている。
なお、このような構成においても、空気口22bには、本体3が姿勢変化した際に、貯留室5内に充填されている液体が入り難いように設定されることが好ましい。
このようなリザーバ室30を形成しておくと、本体3をシェイクし過ぎて、液体が多量に流路10aから流出しても、そのような余剰の液体を貯留しておくことが可能になるため、連続的な塗布が可能となり、また、キャップ13を取り外した際に、本体3をシェイクしなくても、直ちに塗布することも可能となる。
また、このようなリザーバ室30を形成する場合、そのリザーバ室に液体を吸蔵する吸蔵体を配設しておいても良い。このような吸蔵体は、塗布体7よりも毛細管力が弱い材料で構成することで、流路10aから流出した液体を一時的に吸蔵することができ、塗布体7の塗布操作によって液体が消費された際、吸蔵された液体を消費することができる。このた、塗布体7が液体リッチ状態になることを抑制することが可能となる。
この実施形態では、隔壁10の流路10aを流出した液体を塗布体7に直接供給するのではなく、隔壁10と塗布体7との間にリザーバ室30を形成すると共に、この部分に液体を移送する中継部材35を設置し、中継部材35を介して液体を塗布体7に案内するように構成している。
この実施形態では、上記したようなリザーバ室を形成することなく、中継部材35をホルダ8に保持している。ホルダ8の本体8Aは、円筒状で軸方向に延びており、その内部に、一体化された塗布体7と中継部材35を保持している。
このような構成では、中継部材35の保持状態が安定すると共に、その周囲に隙間S1を安定して形成し易くなる。
この実施形態では、貯留室5内に、軸方向に移動可能な液体撹拌用の錘40が配設されている。錘40には、その中心領域に軸方向に貫通する貫通孔40aが形成されており、この部分に、空気連通パイプ15が挿通されている。
この実施形態では、空気連通パイプ15内に、軸方向に延出する棒状部材50が配設されている。
棒状部材50は、一定の重さを備えており、本体3をシェイクした際、撹拌部材22の内面22cに当て付いて、空気連通パイプ15を付勢手段の付勢力に抗して移動し易くする機能を備えている。また、液体の抵抗が作用しないため、空気連通パイプ15よりも早く落下することができ、貯留室5内の液体(流量調整部10e内の液体)を流路10aに案内することが可能となる。すなわち、棒状部材50が空気連通パイプ内で移動することで、流路付近で液体が詰まること、乾燥すること等を効果的に防止することが可能となる。
このような構成では、棒状部材50が中継部材としての機能を果たすことができ、塗布体に対する液体の供給をスムーズに行なうことが可能となる。
この実施形態では、図8に示した棒状部材50の後端部を撹拌部材22に嵌合させて、空気連通パイプ15と棒状部材50が一体的に連動するようにしている。また、棒状部材50の先端側は、流路10a、リザーバ室30及び塗布体7に形成された凹所7aを通過して、バネ部材20Aの付勢力によって塗布体7に接触するようにしている。
この実施形態では、上述したキャップ13に隔壁13aを形成し、その内部に貯留室13bを形成し、貯留室13b内に溶剤13Aを充填している。貯留室内の溶剤13Aは、隔壁13aに形成された貫通孔13cを通じて塗布体7に接触可能となっており、これにより、塗布体7が乾燥することを防止することが可能となる。
この実施形態では、隔壁10の流路10a内に、塗布体側に流れ込む液体の流出量を調整する中継部材10fを挿入、固定している。この実施形態の中継部材10fは、一端側が空気連通パイプ15内に一定の隙間を有して入り込んでおり、他端側は、塗布体7と接触した状態となっている。このように流路10a内に、中継部材10fを設置することで、空気連通パイプ15がシェイク等によって隔壁10から離間した際、塗布体7側に流れ込む液体の流出量(流出速度)を調整することが可能となる。
上記した中継部材は、繊維の収束体以外にも、ポリアセタール(POM)等のプラスチック製による成型品として構成されていても良い。これらの図に示すプラスチック製の中継部材10fa,10fb,10fcは、いずれも隔壁10の流路10a内に嵌合されるものであり、軸方向に沿って毛細管力の強い部分と弱い部分が形成された調整流路10a´を備えている。すなわち、毛細管力の弱い部分に空気が流れると共に、毛細管力の強い部分に液体が流れることで、塗布体7に供給される液体の流出量(流出速度)が調整される。
図1に示した構成は、空気連通パイプ15の先端縁15cを、直接、隔壁10に当て付けることで流路10aをシールするようにしたが、シール性を補助する部材として、先端縁15cと隔壁10との間に、別途、シール材16を介在しても良い。シール材16は、柔軟性のある素材で構成することが好ましく、シリコン、ゴム、綿等を板状に形成したものを用いることができる。シール材16の中心には、流路10aよりも径が大きい連通孔16aが形成されており、このようなシール材を空気連通パイプ15と隔壁10との間に設置することで、空気連通パイプ15が付勢手段によって押圧された際の密着性の向上を図ることができ、シール性を高めることが可能となる。
本発明は、隔壁10に流路10aを形成し、その流路を閉塞するように、空気連通パイプ15を隔壁に付勢すること、及び、空気連通パイプ15を介して貯留室5内に空気を連通させること、本体3をシェイクして、空気連通パイプ15を隔壁から離間して貯留室内の液体を流路10aから流出させることに特徴がある。このため、塗布体7や隔壁10の構成、外部から空気連通パイプ15に至る空気を通過させる経路については、適宜変形することが可能である。
また、貯留室5の大きさ(容積)、空気連通パイプ15の太さや長さ、空気連通パイプ15の移動ストローク等は、塗布具の用途(収容される液体の粘度や収容量)に応じて、その構成を適宜変形することが可能である。
