PROBLEM TO BE SOLVED: To provide an application container which can reduce impact force due to a liquid medicine when a posture of the container is changed from an upward posture to a downward posture.SOLUTION: An application container (10) comprises a bottom wall (20), a trunk part (30), and a mouth part (80), in which the trunk part (30) has: a base part (40)； a diameter-shrunk part (50)； an interposition part (60) interposed between the diameter shrunk part (50) and the mouth part (80)； and a back side neck part (70) for connecting the interposition part (60) and the mouth part (80) at a position opposite to a side where the bottom wall (20) is positioned with a center axis (A) as a reference, in a direction orthogonal to the center axis (A) of the mouth part (80). An inner surface of a first abdominal side boundary (31) between the base part (40) and the diameter shrunk part (50) is curved so as to become salient outward, and an inner surface of a second abdominal side boundary (32) between the diameter shrunk part (50) and the interposition part (60) is curved so as to become salient inward.SELECTED DRAWING: Figure 3【課題】上向き姿勢から下向き姿勢にしたときの薬液による衝撃力を低減可能な塗布容器を提供すること。【解決手段】塗布容器（１０）であって、底壁（２０）と、胴部（３０）と、口部（８０）と、を有し、胴部（３０）は、基部（４０）と、縮径部（５０）と、縮径部（５０）と口部（８０）との間に介在する介在部（６０）と、口部（８０）の中心軸（Ａ）と直交する方向について中心軸（Ａ）を基準として底壁（２０）が位置する側とは反対側の位置で介在部（６０）と口部（８０）とを連結する背側首部（７０）と、を有し、基部（４０）と縮径部（５０）との第１腹側境界（３１）の内面は、外向きに凸となるように湾曲する形状を有しており、縮径部（５０）と介在部（６０）との第２腹側境界（３２）の内面は、内向きに凸となるように湾曲する形状を有していること。【選択図】図３
