    Abstract: A dispenser comprises a frame that supports a roll of adhesive tape, a handle, a flexible spatula for applying the cut end of the tape, and a cutting blade. The flexible spatula forms a right-angled member having a main arm and another arm which supports the cutting blade. The right-angled member is mounted so as to be rotatable between a rest position, in which the cutting blade is pressed by a spring against a protective member, and a working position, in which the cutting blade is lifted from the protective member so that serrations thereon intersect the path of the adhesive tape. This protective member has a face, on which the blade rests, and which ends in a projecting lip, forming a frontal protection for the serrations on the blade.

    Abstract: A dispenser from which sheet material may be dispensed from a supply of the sheet material carried on the dispenser. The dispenser has a frame on which the roll of sheet material is journaled for rotation about its axis. An elongate blade fixed to the frame has a sharp cutting edge that is adapted for transversely cutting the sheet material after a desired length of the sheet material has been dispensed. A guard strip of resiliently movable material extends along one major surface of the blade and along the cutting edge to help protect the sheet material and/or users of the dispenser from the cutting edge. That guard strip is resiliently movable by pulling the sheet material toward the cutting edge to allow the cutting edge to transversely sever the sheet material being pulled from the dispenser.
