The present invention requires a relatively small number of additional parts to solve problems such as the spewing of a content fluid and the occurrence of a residual liquid, at the time of opening a drinking mouth portion. A drinking mouth portion (15) pointing upward is provided on a plug body (4) of a container main body (2) having a sealed structure. A beverage cylindrical member (16) pointing downward is built into the container main body (2) and has a front edge side thereof communicated with the drinking mouth portion (15). Provided inside a fluid passage (21) of the beverage cylindrical member 16 is a membrane (32) movable in accordance with a pressure difference therein. An up-pointing cut-out section (40) is provided on a lower edge (31E) of the beverage cylindrical member (16). That is, the membrane (32) is not manually opened and closed, but is configured to be able to react to a suction force occurring in the fluid passage (21). Therefore, only a relatively small number of additional parts are needed to solve a problem such as the spewing of a content fluid that occurs at the time of opening a drinking mouth (15A). Further, the up-pointing cut-out section (40) provided on the lower edge (31E) allows one to drink up the content fluid remaining in an inner bottom section (34). |
