Definitions

  • CIGARETTES This invention provides a new means for rarefication of the smoke of cigarettes, to provide a cooler, lighter, more flavorful smoke.
  • longitudinal openings be provided in the wrapper of the cigarette along a line defining the outermost end of the radius thereof at the point where the edges of the wrapper overlap. These openings permit the intake of air which is mixed with the smoke of the burning tobacco, causing the smoke to be rarefied as it is drawn toward the mouth of the smoker. The rarefied smoke causes a lesser amount of combustion products to be deposited upon the unburned tobacco as the smoke is drawn therethrough. In conventional cigarettes, such combustion products in the form of particulate matter coat the tobacco and such products in gaseous form permeate the tobacco leaf or fiber, creating an adverse effect upon the flavor of the smoke as the latter portion of the cigarette is burned.
  • the openings of the present invention are created by inter mittent sealing of the wrapper upon fabrication of the cigarette, thus creating-alternating areas of sealing and nonsealing of the wrapper.
  • the diaphragm action of the wrapper at the nonsealed points causes the inner edge of the wrapper to be retracted upon inhalation by the smoker, while upon free burning and particularly upon exhalation, a reverse diaphragm action closes the openings by forcing the inner edge of the wrapper into closer proximity to the outer edge, causing substantial closure of said openings.
  • FIG. 1 is a perspective view of a cigarette having alternating openings along the line of sealing of the wrapper;
  • FIG. 2 is a view on line 2-2 of FIG. 1, showing one portion of the wrapper where sealing has been effected;
  • FIG. 3 is a view on line 3-3 of FIG. 1 showing the wrapper at a nonsealed point, with the two edges of the wrapper overlapped.
  • FIG. I a cigarette 10 is shown with tobacco l1 enclosed by wrapper l2, and edge 13 overlapping edge 14 of said wrapper, with nonsealed portions 15,15 of said wrapper alternating between sealed portions 16,16.
  • the sealed portions extend across the whole width of the overlap, as in FIG. 2.
  • FIG. 2 shows the point of sealing 17 of one of said sealed portions
  • FIG. 3 shows an opening 18 created by one of the nonsealed portions of the wrapper.
  • a cigarette comprising a body of tobacco and a wrapper, said wrapper being in the form of a sheet having the edges thereof longitudinally overlapped, and having in said overlapping edges longitudinally spaced sealing means forming alternate spaced areas sealed across the whole width of said overlap, and other areas being unsealed, to create pockets permitting the passage of air therethrough.
