Abstract
Description
図1に示すように、本実施形態の塗布容器1は、被塗布部に塗布する内容液が収容される有底筒状の容器本体2と、容器本体2の口部10の内側に装着された筒状の塗布栓3と、容器本体2の口部10に離脱可能に装着され、塗布栓3を覆う有頂筒状のオーバーキャップ4と、を備えている。なお、内容液としては、特に限定されるものではないが、例えば人体や皮膚等の被塗布部に塗布される育毛剤、水虫薬等の薬剤、化粧料等の液体が挙げられる。
この倒立状態では、弁体22cが自重により、弁体支持部22bの下端部から離れ、弁座22aに向かって移動する。この弁体22cの移動によって、弁体収容部22内の内容液が含浸材収容部21に押し出され、含浸材30に含浸される。そして、弁体22cが弁座22aに接触すると、弁体収容部22から含浸材30への内容液の供給が制限される。すなわち、弁体22cの上下動により、一定量の内容液が含浸材30に供給される。この状態で、含浸材30を被塗布部に押し付けることで、内容液を被塗布部に適量塗布することができる。なお、オーバーキャップ4を装着した容器本体2を倒立状態として適度に振ることにより、予め含浸材30に内容液を含浸させてもよい。
