Abstract
A drinking mouth portion pointing upward is provided on a plug body of a container main body having a sealed structure. A down-pointing beverage cylindrical member is built into the container main body and has a front edge side thereof communicated with the drinking mouth portion. Provided inside a fluid passage of the beverage cylindrical member is a valve movable in accordance with a pressure difference therein. The valve is not manually opened and closed, but reacts to a suction force in the fluid passage. An up-pointing cut-out section is provided on a lower edge of the beverage cylindrical member, thus allowing one to drink up a content fluid remaining in an inner bottom section. Therefore, a relatively small number of additional parts are needed to address the spewing of a content fluid and the occurrence of a residual liquid at the time of opening the drinking mouth portion.
