The handle is inserted into a hollow core. The fins provide a fit that allows the core to rotate relative to the handle. The fins can deform when subjected to such rotation. The grip is positioned to allow the user to squeeze the handle against the core to slow or stop said rotation. ## Claims ### Claim 1 A handle for use with a hollow core having an inner diameter comprising: (a) an insert portion having an internal surface and an external surface; (b) a grip surface integral within the insert portion to allow the handle to be grasped; and (c) a plurality of rigid load-bearing supports operatively disposed between the grip surface and the internal surface of the insert portion; and (d) a plurality of fins extending from the external surface of the insert portion to frictionally contact and allow manipulation of the inner diameter. ### Claim 2 (depends on 1) The handle of claim 1 further comprises (e) an annular outer flange having its inner periphery attached to the insert portion. ### Claim 3 (depends on 1) The handle of claim 1 wherein the insert portion has a generally cylindrical shape and has an outer diameter approximately equal to the inner diameter of the hollow core. ### Claim 4 (depends on 1) The handle of claim 1 wherein said plurality of fins are deformable. ### Claim 5 (depends on 1) The handle of claim 1 wherein said plurality of fins are deformable in response to a rotational force. ### Claim 6 (depends on 1) The handle of claim 1 wherein the fins are sized to permit controlled axial rotation of the hollow core around the insert member. ### Claim 7 (depends on 1) The handle of claim 1 wherein the fins form an outer insert diameter approximately equal to the inner diameter of the hollow core. ### Claim 8 A handle for use with a hollow core, for holding a web of material, the core having an inner diameter, the handle comprising: (a) an insert portion having an internal surface and an external surface (b) a plurality of fins extending radially from the external contact the inner diameter of the core; (c) an outer flange attached to the external surface of the insert portion, the flange having an outer diameter greater than the inner diameter of the core to locate the handle in the core; (d) a grip surface transversely integral within the internal surface of the insert portion; and (e) a plurality of rigid load-bearing supports connecting the grip surface and the internal surface of the insert portion. ### Claim 9 (depends on 8) The handle of claim 8 wherein said insert portion is substantially cylindrical. ### Claim 10 (depends on 8) The handle of claim 8 wherein the fins form an outer diameter approximately equal to the inner diameter of the hollow core. ### Claim 11 (depends on 8) The handle of claim 8 wherein said plurality of fins are deformable. ### Claim 12 (depends on 8) The handle of claim 8 wherein said plurality of fins are deformable in response to a rotational force applied by the core. ### Claim 13 A method of dispensing a web of material from a hollow core having an inner diameter, the method comprising the steps of: (a) providing a handle having an insert portion with a plurality of fins extending radially therefrom, the handle having an interior diameter, a grip surface and plurality of load-bearing supports connecting the grip surface and the insert portion; (b) inserting the insert portion into the hollow core; (c) gripping the grip surface; and (d) dispensing the web of material by controlling the rotation of inner diameter of the hollow core relative to the grip surface. ### Claim 14 (depends on 13) The method of claim 13 further comprises: (d) pressing said handle against said core to increase the friction therebetween, thereby stretching said web. ### Claim 15 A dispenser handle for use with a hollow core, the hollow core having an inner diameter, the handle comprising: (a) an cylindrical insert portion having a first end, a second end, an inner surface and an outer surface, wherein the diameter of the outer surface is less than the inner diameter of the hollow core; (b) a concave grip surface; (c) a plurality of rigid stanchions, generally perpendicular to the grip surface, integrally disposed between the grip surface and the inner surface of the first end of the insert portion, providing support for the grip surface; (d) an annular flange having its inner periphery attached to the outer diameter of the first end of the insert portion, adapted to abut one end of the core to locate the handle within the core, and (e) a plurality of fins attached radially to the outer diameter of the insert portion, such fins laterally positioned between the first end and the second end of the insert portion, such fins being flexible to allow controlled rotational movement of the hollow core by producing friction between the inner diameter of the hollow core and the fins. ### Claim 16 A handle for holding rolled material wrapped around a hollow core comprising: (a) a cylinder sized to fit within the hollow core; (b) a flange attached to the cylinder at one end sized to abut the edge of the core when the cylinder is fitted within the core; (c) a grip surface supported within the cylinder by radial stanchions; (d) a plurality of radial fins longitudinally attached to the cylinder which are deformable to allow friction or contact with cores of different sizes. ### Claim 17 (depends on 16) The handle of claim 16 wherein the handle is made of plastic. ### Claim 18 (depends on 16) The handle of claim 16 wherein the cylinder is rigid.
