A tape dispenser comprises a housing, a reel core (3) rotatable in the housing about an axis and having an inner periphery formed with an annular array of inwardly directed core teeth (17), and a drive wheel rotatable in the housing about the axis. A plurality of elastically deformable spring tongues (15) formed unitarily with each other each extend at an angle to the axis from the respective inner end fixed to the drive wheel to a respective outer end lying within the reel core adjacent the inner periphery thereof. Each inner end is axially offset and radially inwardly offset from the respective outer end and each outer end is integrally formed with at least one tongue tooth engaging between the core teeth. A supply of tape (14) is wound on the reel core such that when the tape is payed out or wound up on the reel core same rotates relative to the drive wheel and the core teeth move angularly relative to the tongue teeth with elastic inward deflection of same.
