Work Supply Nonrotatably Wound On Flanged Spool Patents (Class 225/59)
  • Patent number: 6491082
    Abstract: A safety for blade of tape dispenser includes a fixing seat provided above a tape roller of the tape dispenser. The fixing seat defines an inner space in which a blade of the tape dispenser is fixedly mounted and a shield plate is disposed above the blade. The shield plate includes two legs configured to have some degree of elasticity and connected at outmost ends to the fixing seat to normally project a front edge of the shield plate beyond a serrated front edge of the blade when the tape dispenser is not in use or is used to apply a length of tape on a surface. When the tape dispenser is used to cut the length of applied tape, the two elastic legs allow the shield plate to slide backward under a tension of the tape to expose the blade for cutting the tape.
