PROBLEM TO BE SOLVED: To provide a straw which is easy to store in and pull out from a container of a plastic bottle and so on, and has a simple structure. SOLUTION: Restoration to flexion is given to a bellows part by coating with high elastic synthetic resin and so on near the external surface of a straw with a fold by one or more bellows or the bellows part. Thereby, the straw is stored in a container such as a plastic bottle and so on by bending the bellows part when storing. The bellows part is restored from bending by removing the top of the container such as the plastic bottle and so on when pulling out. A straw tip appears naturally from the container opening of the plastic bottle and so on. COPYRIGHT: (C)2006,JPO&NCIPI
