Claims (14)

A handle fitting to the open end of the roll core for supporting the roll core, the roll core being rotatable relative to the handle;
A hollow holder body having a proximal end and an end wall, the holder body having a length extending from the proximal end to a central portion of the holder body and a distal portion extending from the proximal portion to the end wall Divided in a direction, the proximal portion having an outer diameter adapted to fit to the open end of the roll core, rotatably supporting the roll core, and the distal portion having a smaller outer diameter than the proximal portion. The holder body further prevents the direct contact with the inner surface of the roll core and further allows the roll core to rotate smoothly relative to the holder body longitudinally around the proximal portion. A holder body having a plurality of side-by-side arcuate segment sidewalls provided, and extending radially outward from a proximal end of the holder body; Gradual flange,
With handle. The arcuate segment extends from the proximal end to the end wall, the distal portion tapers to the inner portion, provides a sliding fit at the open end of the roll core, and the distal portion has no taper The handle of claim 1, wherein the handle provides a compression fit to the open end of the roll core. The distal portion equally reduces its outer diameter, forms a finger-holding portion, defines a stepped shoulder between the proximal portion and the distal portion, thereby defining an air gap around the distal portion Providing a cushioning effect that prevents the distal portion from making substantial contact with the inner surface of the roll core while the roll core rotates relative to a handle supported at the open end of the roll core. Item 1. The handle according to Item 1. A flange of the handle is integral, is a peripheral wall located around the proximal end of the holder body and extends outwardly, the flange being a peripheral stiffening lip; and the stiffenin The handle of claim 2, providing a plurality of spatially spaced integral corner ears extending radially outward from the grip. A flange of the handle is integral, is a peripheral wall located around the proximal end of the holder body and extends outwardly, the flange being a peripheral stiffening lip; and the stiffenin 4. The handle of claim 3, wherein the handle provides a plurality of spatially spaced integral corner ears that extend radially outward from the grip. Each of the corner ears has an indentation button indented inwardly thereon to reinforce the corner ears and bias against the distal side of the roll core, ensuring a smooth rotation of the roll core; The handle according to claim 4. The handle of claim 4, wherein a plurality of indented tips are provided on the stiffening lip spatially apart to reinforce the stiffening lip and ensure smooth rotation of the roll core. 7. A handle according to claim 6, wherein at least one claw notch is formed on one side of each of the corner ears to ensure that the handle is securely gripped and held during rotation of the roll core. The holder body further comprising a plurality of spatially separated axially oriented stiffening ribs formed longitudinally around the holder body, the holder body being compressed The handle of claim 2, wherein the handle provides flexing and the stiffening ribs are movable radially inward to create a strong spring force and provide grip to the roll core. The holder body further comprising a plurality of spatially separated axially oriented stiffening ribs formed longitudinally around the holder body, the holder body being compressed The handle of claim 7, wherein the handle provides flexing and the stiffening ribs are movable radially inward to create a strong spring force and provide grip to the roll core. Each group of rotor supports includes two or more arched segments constructed in a continuous undulating configuration, providing an arched smooth, rounded bearing surface, and a roll core that rotates smoothly around the handle 12. A handle according to claim 11, wherein the handle is enabled. Each of the stiffening ribs has a depth deeper than the curvature of the arcuate segment, and provides an outward spring bias deflection effect for a group of rotor supports adjacent to each of the stiffening ribs. The handle of claim 11, provided. A handle fitting to an open end of a roll core for supporting the roll core, the roll core being rotatable with respect to the handle, the handle being
A hollow holder body having a plurality of side-wall arched segments and a plurality of stiffening ribs formed longitudinally around the holder body, wherein the stiffening ribs are spatially separated The plurality of arcuate segments positioned into a group of resilient rotor supports adapted to and derived from such a compressive constraint in the roll core; A hollow holder body that allows it to rotate smoothly with respect to the holder body, and an independent flange extending radially outward from the proximal end of the holder body,
With handle. At least one cylindrical handle providing a generally tubular side wall, the side wall comprising a plurality of side-by-side arcuate segments for applying an outward spring bias deflection to secure the roll core inside one end thereof; And a handle for providing an axially oriented seam that can separate the sidewalls, and means for sealing the axially oriented seam.
