As for this invention, being the application liquid of high viscosity, simply not only being able to apply, it builds in from the air and microbial contamination etc from outside can protect the application liquid which it is the liquid application tool which, pressurizes the application liquid 4 inside substance 2 it possesses the liquid pushing pressure expedient 6 which, with the pushing pressure of said liquid pushing pressure expedient 6 it tries to supply the application liquid to application body 10 of the point in the liquid application tool which, the aforementioned application body 10 consists of the elastic material, inside substance 2 leads outside the communication road 24 whichBeing formed, in normal state to stop the said communication road 24 with elasticity, at the same time the application liquid the occasion where it was pressurized by liquid pushing pressure expedient 6, the said communication road 24 becoming deformed, elasticity to possess the valve gear 8 which it can open, because emission mouth 24of a communication road 24 of valve gear 8 is faced to the application part 10of a said application body 10, being the application liquid of high viscosity, it stops valve gear securely with normal state.本発明は、高粘度の塗布液であっても、簡便に塗布し得るだけでなく、外気や外部からの微生物汚染等から内蔵する塗布液を保護することができる液体塗布具であり、本体2内部の塗布液4を加圧する液押圧手段6を具備し、該液押圧手段6の押圧により塗布液を先端の塗布体10へと供給するようにした液体塗布具において、前記塗布体10は、弾性材からなり、本体2内部と外部に通じる連通路24が形成されていて、常態において該連通路24を弾性によって閉止し、且つ塗布液が液押圧手段6によって加圧された際に、該連通路24が弾性変形して開放しうる弁機構8を有し、該塗布体10の塗布部分10aには、弁機構8の連通路24の吐出口24aが臨んでいるので、高粘度の塗布液であっても、常態で弁機構は確実に閉止する。
