PROBLEM TO BE SOLVED: To provide an ampoule vessel which includes a body for holding a content liquid and a head that is shaped of a crested cylinder and connected to the top of the body to unite with each other, but broken off from the body to give the body an opening, wherein the remaining content liquid is removed from placing in the head when the ampoule vessel is put upright, in order that the content liquid is prevented from scattering and flowing out when the ampoule is amputated to open, and that an appropriate amount of the content liquid can be held.SOLUTION: An ampoule includes a weakened site 9 which is formed in a boundary between a body 1 for holding a content liquid N and a head 6, and the ampoule vessel further is provided with at least one vertical rib 8 which runs downwards from the lower level relative to the weakened site 9, wherein the vertical rib 8 is positioned on the internal circumferential surface part 7 to which the peripheral end of the bottom surface n1 of a remaining content liquid n situating within the head 6 sticks, so that a sticking force and a surface tension of the remaining content liquid n working on the internal circumferential surface part 7 are inhibited from working equally along the internal circumferential surface, leading to a result that the remaining content liquid n flows freely down into the body 1.COPYRIGHT: (C)2014,JPO&INPIT【課題】 内容液を収容する本体部の上端に、有頂筒状の頭部を一体に連設し、頭部の本体部からの破断により本体部を開口するアンプル容器において、容器を正立状態では頭部内に、残留内容液を位置させないことにより、開封時における内容液の飛散や流出を防止し、内容液の適正な量の収容を得る、ことを目的とするものである。【解決手段】 内容液Nを収容する本体部1と頭部6の境界部に形成された弱化部9を有し、内周面に、弱化部9よりも下位から下方に延びる少なくとの1本の縦リブ8を設け、この縦リブ8を、頭部6内に位置する残留内容液nの下端液面n1の周端縁が付着する内周面部分7に位置させて、この内周面部分7に作用する残留内容液nの付着力と表面張力が均等に作用するのを阻止し、もって残留内容液nを本体部1内に自然流下させる。【選択図】 図1
