Abstract
An environmentally-friendly fiber straw structure includes a straw body made of an environmentally-friendly fiber material. The straw body has an inlet and an outlet at two ends thereof and a circular section having a circular cross-section between the inlet and the outlet. From the circular section to the outlet forms a first tapered section at a first inclination so that the outlet has an approximately elliptical shape. When in use, the mouth of a user sucks the outlet of the straw body for drinking a beverage, the first tapered section corresponds in shape to the mouth, thereby avoiding rotation of the straw body, reducing a gap between the mouth and the straw body.
