Easy to roll curved edge cigarette rolling paper

Abstract

A cigarette rolling paper that has three straight edges and one edge curved so that the curved edge can easily be tucked in as the user starts to roll the cigarette, without catching on a corner, which is one of the problems when hand-rolling. With traditional rectangular papers, the top and bottom edge must remain parallel to each other or the leading corner gets caught up and doesn't tuck. This common challenge is somewhat hard to avoid. The curved edge provides increased tolerance for this inaccuracy, and facilitates an easy roll.

What is claimed is: 
     
         1 . A cigarette rolling paper comprising one edge shaped as a convex curve, and three straight edges. 
     
     
         2 . The cigarette rolling paper of  claim 1 , wherein said curve is a generally smooth continuous arc with no significant corners or inflection points. 
     
     
         3 . The cigarette rolling paper of  claim 2 , wherein said curve is selected from the group consisting of a regular arc, an irregular arc, a circular arc, an elliptical arc and a complex arc. 
     
     
         4 . The cigarette rolling paper of  claim 3 , wherein the cigarette rolling paper is adapted to roll into a cigarette having a circumference, wherein said curve includes a deflection having a length approximately ¼ of the circumference. 
     
     
         5 . The cigarette rolling paper of  claim 4 , wherein said curve deflection is proportional to the size of the rolling paper. 
     
     
         6 . The cigarette rolling paper of  claim 5 , wherein said curve includes a midpoint that is located in the middle of curved edge of the cigarette rolling paper. 
     
     
         7 . The cigarette rolling paper of  claim 6 , wherein said curve includes one deflection at each end of the cigarette rolling paper. 
     
     
         8 . The cigarette rolling paper of  claim 1 , wherein the cigarette rolling paper comprises cigarette papers of any size or material. 
     
     
         9 . The cigarette rolling paper of  claim 1 , further including glue at one end of the cigarette rolling paper opposite said curve. 
     
     
         10 . The cigarette rolling paper of  claim 9 , wherein the cigarette rolling paper is adapted to roll into a cigarette beginning at said curve and ending at said glue end. 
     
     
         11 . The cigarette rolling paper of  claim 1 , wherein the cigarette rolling paper has a thickness between about 0.25 mm and about 2.00 mm, a length L between about 60 mm and about 100 mm, and a width W between about 35 mm and about 45 mm, and wherein the cigarette rolling paper is made from a material suitable for burning and human inhalation. 
     
     
         12 . An apparatus for hand rolling a cigarette comprising:
 a cigarette rolling paper having a generally rectangular shape with three rectilinear sides and a one curved side;   said three rectilinear sides form three sides of a regular rectangle comprising (i) a first rectilinear side oriented perpendicular to a second rectilinear side, (ii) a third rectilinear side oriented perpendicular to said second rectilinear side, and (iii) said first rectilinear side being parallel to said third rectilinear side; and   said curved side comprising an elliptical arc having an arch height and an arch width that contacts the end points of said first and third rectilinear sides to form a closed figure;   wherein said cigarette rolling paper has reflective symmetry about a central axis that is collinear with the arch height.   
     
     
         13 . The apparatus of  claim 12 , wherein the cigarette rolling paper is made from a material suitable for burning and human inhalation. 
     
     
         14 . The apparatus of  claim 13 , where said curved side is devoid of angular edges or sharp corners. 
     
     
         15 . The apparatus of  claim 14 , wherein the second rectilinear side has a width W, and the arc is part of an ellipse having a major axis, wherein the length of the major axis is between 1 and 10 times the width W. 
     
     
         16 . The apparatus of  claim 15 , wherein the first and third rectilinear sides have a length L minus deflection, and the arc is part of an ellipse having an arch height, wherein the length of the arch height is between ⅕ and ⅛ times the length L. 
     
     
         17 . The apparatus of  claim 16 , wherein the cigarette rolling paper has a thickness between about 0.25 mm and about 2.00 mm, a length L between about 60 mm and about 100 mm, and a width W between about 35 mm and about 45 mm. 
     
     
         18 . The apparatus of  claim 17 , wherein the region between the elliptical arc and the first and third rectilinear sides comprises a slope matched transition and includes a curvature different from the central portion of the elliptical arc. 
     
     
         19 . The apparatus of  claim 18 , wherein the cigarette rolling paper is made from a material selected from cellulose, plant fibers, rice, flax, hemp and tobacco. 
     
     
         20 . The apparatus of  claim 19 , wherein the elliptical arc is a geometric segment from an ellipse having a major axis that is between about 2 times and about 10 times the length of the minor axis.
