A foldable drinking straw made of paper, comprising:
- a circular section developing along a longitudinal axis, comprising a flexible shaped portion configured to allow a folding, one over the other, of two adjacent portions of the straw, said flexible shaped portion being defined by a plurality of depressions, disposed in succession along said longitudinal axis and each made on a limited circumferential portion of the circular section of said straw, and wherein said plurality of depressions comprises groups of depressions disposed along the longitudinal development of said flexible shaped portion and angularly offset with respect to each other.
A method to make a foldable drinking straw made of paper, comprising:
- providing a circular section developing along a longitudinal axis, making, along a cylindrical tubular body of paper, a plurality of depressions disposed in succession along said longitudinal axis and each made, transversely to said longitudinal axis, on a limited circumferential portion of the circular section of said cylindrical tubular body of paper, defining a flexible shaped portion configured to allow a folding, one over the other, of two adjacent portions of the straw, said method also comprising making, along said cylindrical tubular body of paper, groups of depressions, disposed along the longitudinal development of said flexible shaped portion and angularly offset with respect to each other.
