This invention relates to a straw made of synthetic resin of normal round tube shape in which air passing through hole capable of introducing exterior air is formed at a place perforated by said straw so that phenomenon becoming to vacuum within the interior of container is prevented. The invention is constructed in such a manner that at least one or more lengthwise groove(s) (2) for producing exterior air introducing hole or protuberance(s) (6a, 6b) are formed along the lengthwise direction of a straw (1) except top end portion (4) and bottom end portion (5) in case of the groove(s) (2). According to the invention, since exterior air introducing hole is produced at a place perforated by the straw simultaneously upon inserting with it, content within a container such as carton pack is conveniently sucked without such phenomenon becoming to vacuum of carton pack. |
