Abstract: This invention, a tape dispenser with a sliding tape axle, is designed to eliminate the problem and disturbance of a loosened or missing tape axle of traditional tape dispensers with separate parts joined together. It uses a structure that fastens the tape axle and the base together. Its tape axle is a cylindrical body with a pair of sliding slots on one side to match a pair of horizontal tenons on a sunken surface of the base, and a pair of tenons at its bottom surface to fix the tape axle into an insertion slot in the sunken surface on one end and a sunken rim on the other side of the tape compartment, restricting the horizontal movement of the tape axle and avoiding its loosening from the base, and thus forming a tape dispenser with a sliding tape axle.
