Drinking straw

Abstract

This article is formed in a cylindrical shape, with one end inserted into a beverage container, and the user drinking the beverage from the other end. The article has protrusions that extend along its entire axial length by bulging radially outward on the peripheral wall, and six of these protrusions are arranged at equal intervals around the circumference of the article. Each of these six protrusions is formed in a spiral shape from one end to the other, and the spiral shape is such that each protrusion is twisted by the length between adjacent protrusions at both ends. As a result, a spiral pattern is formed on the peripheral wall of the article by the six protrusions, and a flower pattern resembling six petals is formed on the end face and the other end face.
