Patent ID: 8181899

Claim:
A dispenser for dispensing a wound dry sheet of paper made of tissue paper, comprising: a cylindrical body; support elements, lying approximately in the same plane, disposed and configured for resting the dispenser on a horizontal plane; a slot in the cylindrical body disposed and configured for the sheet of paper to exit, said slot lying along the cylindrical body, in a region substantially diametrically opposed to the plane containing the support elements; a guiding element disposed and configured for guiding the sheet of paper outside the cylindrical body, associated with said slot, comprising two mutually parallel surfaces, wherein the two surfaces are curved, in that a defined distance E between the two curved surfaces is greater than twice a defined thickness E p of the sheet of paper and in that a defined length L of the guiding element, measured along the direction of unwinding the paper, is equal to or greater than twice a minimum length L m of the guiding element, wherein: L m =2× π×R×A/ 360, where A=2×arc cos((R−E+E p /2)/(R−E p /2)), and where R=radius of curvature defining the outer curved surface; E=distance between facing faces of the two surfaces; E p =thickness of the paper sheet.
