  • Publication number: 20200054157
    Abstract: A paper straw has an inner tube, an outer tube, and a pattern portion. The inner tube and the outer tube are both tubular bodies formed by spirally winding paper sheets. The pattern portion is disposed between the inner tube and the outer tube. The paper sheets that are used to wind the inner tube and the outer tube have light-transmissive properties. Then the pattern portion can be externally displayed through the outer tube or the inner tube, and this can avoid the pattern portion directly contacting food or human body.
