PROBLEM TO BE SOLVED: To prevent a liquid content from scattering or spilling out in opening an ampule container by preventing a residual liquid content from being positioned in a head portion, in the ampule container in which a topped cylindrical head portion is integrally provided at the upper edge of a body portion for storing the liquid content and the body portion is opened by breakage of the body portion of the head portion.SOLUTION: A recessed and projected surface part 8 is formed by plural longitudinal ribs 9 for preventing the surface tension of a residual liquid content n from being exerted uniformly on an inner peripheral surface part 7 to which the peripheral edge of a lower-edge liquid surface n1 of the residual liquid content n positioned in a head portion 6 is stuck, the plural longitudinal ribs 9 having different height positions of the upper edge are mixed, and the residual content liquid n is reliably naturally fallen into a body portion 1 by the change in increase in the number of the longitudinal ribs in contact with the peripheral edge of the lower-edge liquid surface n1 of the residual content liquid n.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、頭部内に、残留内容液が位置しないようにすることにより、開封時における内容液の飛散や流出を防止する、ことを目的とするものである。【解決手段】 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、残留内容液nの表面張力が均等に作用するのを阻止する多数の縦リブ9により凹凸面部8を形成し、多数の縦リブ9は上端の高さ位置の異なるものを混在させ、残留内容液nの下端液面n1の周端縁に接触する縦リブ9の数の増加変化により、残留内容液nを本体部1内への自然流下を確実に得る。【選択図】 図1
