Zusammenfassung:To easily remove a cap from a mouth part of a bottle or to open the same.SOLUTION: A cap attached to a mouth part of a bottle comprises a body part 100. The body part 100 has an inner surface IS that engages via a rotating operation with an engaging part provided on the outer periphery of the mouth part, and an outer surface OS which includes a first projecting part PP1 projecting in a first direction when viewed from a central axis AX of the inner surface IS and a second projecting part PP2 projecting in a second direction opposite to the first direction when viewed from the central axis AX. The first projecting part PP1 and the second projecting part PP2 each have a top part AP, a first surface F1, and a second surface F2 connected to the first surface F1 via the top part AP. In a cross section along a plane that includes the central axis AX and intersects the first surface F1, the first surface F1 of the first projecting part PP1 has a concave part CC composed of a smooth curve recessed on the central axis AX side.SELECTED DRAWING: Figure 4 【課題】ボトルの口部からのキャップの取り外しあるいは開栓を容易にする。【解決手段】ボトルの口部に装着されるキャップは、本体部100を備え、本体部100は、口部の外周に設けられた係合部に対して回転操作によって係合する内側面ISと、内側面ISの中心軸AXから見て第1方向に突出した第1突出部PP1および中心軸AXから見て前記第1方向の反対方向の第2方向に突出した第2突出部PP2を含む外側面OSと、を有する。第1突出部PP1および第2突出部PP2は、頂部APと、第1面F1と、頂部APを介して第1面F1に接続された第2面F2とを有する。中心軸AXを含みかつ第1面F1に交差する平面による断面において、第1突出部PP1の第1面F1は、中心軸AXの側に窪むように滑らかな曲線で構成された凹部CCを有する。【選択図】図4
