Summary:PROBLEM TO BE SOLVED: To provide a container having high seal ability between a valve seat part and a valve body part, and in which, a check valve hardly falls, even when a soft resin is used.SOLUTION: A container 100 with a check valve comprises: a trunk 101 for storing a content; a nozzle part 103l and a mouth cylindrical part 102 to which an external fitting type check valve 10 is attached. The mouth cylindrical part has a falling prevention part 106 protruded to inside of the mouth cylindrical part, on a side closer to the trunk side, than the check valve, and the falling prevention part has an opening 106a, therefore the content can be provided to the nozzle part from the trunk through the opening and the check valve 10. The check valve has an outer peripheral cylindrical part 1 and an inner peripheral cylindrical part 2, a valve body part A is provided on one of the outer peripheral cylindrical part and inner peripheral cylindrical part and a valve seat part B is provided on the other of them, namely the check valve is a 2 piece check valve, and when being observed from the trunk side of the container, at least a part of the valve seat part exists inside of the opening.SELECTED DRAWING: Figure 1 【課題】弁体部と弁座部との密封性が高く、柔らかい樹脂を用いても逆止弁の脱落が発生しにくい容器。【解決手段】内容物を収容するための胴部１０１、ノズル部１０３、及び外嵌め式の逆止弁１０を装着している口筒部１０２を有する、逆止弁付きの容器１００であって、口筒部は、逆止弁よりも胴部側に、口筒部の内側に突出している脱落防止部１０６を有しており、かつ脱落防止部が開口１０６ａを有しており、それにより内容物を、胴部から開口と逆止弁１０とを通じてノズル部に提供可能であり、かつ逆止弁は、外周筒状部分１と内周筒状部分２とを有し、弁体部Ａ及び弁座部Ｂが外周筒状部分及び内周筒状部分のいずれかにそれぞれ別れて存在している２ピース逆止弁であり、かつ容器の胴部側から観察したときに、弁座部の少なくとも一部が開口の内側に存在している。【選択図】図１
