Abstract
Disclosed is a drinking straw with valve function adapted to be mounted to a beverage container, the straw including a straw member having a straw body, a bellows portion formed at a desired portion of the straw body, and a tube arranged in the bellows portion while being integral with the straw body and having a desired elasticity, and a straw mounting member for mounting the straw member to the beverage container. The straw mounting member includes a fixed base attached to a top of the beverage container while being in close contact with the top of the beverage container, a straw fitting section formed at one side portion of the fixed base, and adapted to mount the straw member thereto, and a straw holding section formed at the other side portion of the fixed base, and adapted to hold the straw member in a bent state or to release the straw member from the bent state. A cut-out is selectively formed at an inner tube portion of the tube in a region where the inner tube portion bends. The cut-out has a desired shape while serving to provide an improved passage closing function when the bellows portion bends.
