Summary:To suppress a liquid being blocked between an opening end part of a container and a protrusion part of a lid material when the container is tilted.SOLUTION: A lid surface part 100 includes a protrusion part 110 protruding to the opposite side from a container 1 side. A peripheral wall part 150 is erected on the container 1 side from an outer edge of the lid surface part 100, and includes an engagement protrusion part 151 engaged with an opening end part 20. The protrusion part 110 includes: a top surface part 111 positioned at a tip of the protrusion part 110, and having an opening part 112; and an outer peripheral side surface part 113 for connecting the top surface part 111 and the peripheral wall part 150 with each other, and positioned on an outer peripheral side of the protrusion part 110. A boundary B1 between the peripheral wall part 150 and the outer peripheral side surface part 113 is positioned further on the outer peripheral side than an inner periphery 21 of the opening end part 20. The engagement protrusion part 151 is positioned on an outer peripheral side of the opening part 112, when viewed from a direction orthogonal to a virtual plane Pv, and is continuously formed across the whole length of a region where the opening part 112 is positioned in a width direction orthogonal with respect to a radial direction connecting a virtual center 100c of the lid surface part 100 and a virtual center 112c of the opening part 112.SELECTED DRAWING: Figure 3 【課題】容器を傾けた際に容器の開口端部と蓋材の突出部との間で液体がせき止められることを抑制する。【解決手段】蓋面部１００は、容器１側とは反対側に突出した突出部１１０を有する。周壁部１５０は、蓋面部１００の外縁から容器１側に立設され、開口端部２０と係合する係合突起部１５１を有する。突出部１１０は、突出部１１０の先端に位置し、開口部１１２を有する天面部１１１、および、天面部１１１と周壁部１５０とを互いに接続し、突出部１１０の外周側に位置する外周側面部１１３を含む。周壁部１５０と外周側面部１１３との境界Ｂ１は、開口端部２０の内周２１より外周側に位置している。係合突起部１５１は、仮想平面Ｐｖに直交する方向から見て、開口部１１２の外周側に位置しつつ、蓋面部１００の仮想中心１００ｃと開口部１１２の仮想中心１１２ｃとを結ぶ径方向に対して直交する幅方向における開口部１１２が位置する領域の全長に亘って連続して形成されている。【選択図】図３
