Definitions

  • the present invention relates to cigarettes. More particularly, the present invention relates to cigarettes which are adjustable to provide a wide range of air dilution values.
  • the sleeve or filter plug may be removed from the cigarette by the smoker and not readily replaced, and that when dilution is desired, thus requiring some degree of registry between the two sets of openings, this registry may be inadvertently destroyed by a slight axial movement of the sleeve or plug. Accordingly, the dilution, once set by the smoker, is not ensured of any degree of consistency.
  • Yet another problem associated with a number of these prior devices is that they have not been readily adaptable to a high rate of production on cigarette making machinery of conventional design.
  • a smoking article comprising a column of combustible smoking material, and a mouth end region open to permit the passage of air and smoke, characterised in that the mouth end region is circumscribed by substantially air impermeable wrapping having an opening therein, and an outer substantially air impermeable tipping paper having an opening therein, means being provided for rotating one opening relative to the other so that the openings may be in varying degrees of registry to admit varying amounts of air to the mouth end region to dilute the smoke therein and means being provided for retaining the tipping paper against axial movement.
  • a method of making such a smoking article which is characterised in that it ' comprises making two parallel rows of closely spaced perforations in tipping paper to define first, second and third bands axially aligning a tobacco rod and a filter plug in abutting relationship, applying an adhesive to the first and third bands on the same side of the tipping paper, wrapping the adhesive coated side of the tipping paper around the tobacco rod and filter plug, forming an opening through the second band and the underlying wrapping, and then breaking the perforations so that the second band is freely rotatable about the longitudinal axis of the filter plug and retained against axial movement.
  • a smoking article comprising a column of combustible smoking material and a mouth end region open to permit the passage of air and smoke, characterised in that the mouth end region has a peripheral area thereof adapted for the passage of air therethrough, and is circumscribed by a substantially air impermeable sheet material comprising a first band fixed to the mouth end of the smoking article and a second band movable relative to the said peripheral area to admit varying amounts of air to the mouth end region to dilute the smoke therein.
  • the assembly comprises tipping paper and a wrapped cylindrical filter plug.
  • the tipping paper is divided into three bands, the first of which circumscribes a portion of one end of the filter and the adjoining end of the tobacco rod and is attached both to the rod and to the filter plug adjacent the rod end.
  • the middle band contains the opening in the tipping paper and the opening in the plug wrap is positioned beneath this band so that the openings may, through rotation of the middle, band, be moved into registry.
  • the third band is attached to the filter plug adjacent the mouth end thereof. Of the three bands, only the middle band is not attached to the filter plug or the tobacco rod and thus may be rotated about the filter plug, but is secured against axial movement by the fixed first and third bands.
  • the assembly comprises tipping paper, an inner contiguous wrapping and a wrapped cylindrical filter plug.
  • the tipping paper is continuous and the inner layer is divided into three bands.
  • the first band is located at the tobacco rod end of the filter plug and is fixed to the plug wrap. This band contains an opening in registry with an opening in the plug wrap.
  • the second or middle band is not fixed to the plug wrap but is attached to the tipping paper..
  • the third band is located adjacent the mouth end of the filter plug and is fixed to the plug wrap. An opening in the tipping paper is located above the first band.
  • the filter plug may be rotated about its longitudinal axis within the cylinder formed by the tipping paper and is retained against axial movement.
  • the openings are positioned such that rotation of the filter plug will rotate the opening in the first band into registry with the opening in the tippin paper. It is preferred to have the mouth end of the filter plug extend a slight distance beyond the tipping paper so that it may be readily manipulated by the smoker to rotate the openings relative to each other to select the desired degree of dilution.
  • the assembly comprises at least two layers of a wrapping such as tipping paper.
  • the outer wrapping is preferably tipping paper and is constructed as described in connection with the description of the outer wrapping of the first preferred embodiment.
  • the innermost wrappings are either attached to or from the wrapping for the tobacco rod and have an opening positioned beneath the middle band of the outermost wrapping such that the opening therein can be rotated into registry with the opening through the inner wrappings.
  • there is a single inner wrapping which comprises the cigarette paper of the tobacco rod and the outer wrapping is tipping paper which is wrapped around the tobacco rod adjacent the mouth end.
  • the assembly comprises a tobacco rod, an integral-axially aligned substantially cylindrical wrapped filter plug at the mouth end of the tobacco rod, and tipping paper surrounding the filter plug.
  • the plug wrap is divided into a mouth-end band, a central band, and a rod-end band having an opening therethrough.
  • the first and third bands are attached to the filter.
  • the tipping paper circumscribes the filter plug and extends from the mouth end of the filter plug to a position on the tobacco rod adjacent to the rod end of the filter plug.
  • the tipping paper is divided into first and second bands, the first band extending from the mouth end to a position adjacent the tobacco rod overlying the third band of the plug wrap.
  • the second band of the tipping paper abuts the first band of the tipping paper and overlaps and attaches the rod end of the filter to the abutting end of the tobacco rod.
  • the first band of the tipping paper has an opening which is positioned in registry with an opening in the third band of the plug wrap.
  • the first band of the tipping paper is attached to the plug wrap only at the central band for rotation therewith about the longitudinal axis of the filter, whereby the opening in the tipping paper is rotated into varying degrees of registry with the opening in the underlying plug wrap to permit varying amounts of air to combine with the smoke, thereby varying the air dilution value of the cigarette.
  • the air dilution value is the ratio of the volume of air to the volume of smoke exiting the mouth end of the filter and is expressed as a percentage.
  • the assembly comprises a tobacco rod, an integral, axially aligned, wrapped filter plug and two circumscribing layers of tipping paper.
  • the filter is wrapped in an air permeable plug wrap.
  • the tobacco rod and filter plug are joined together by a first circumscribing layer of air permeable tipping paper which extends from the mouth end of the filter plug to a position on the tobacco rod adjacent the rod end of the filter plug.
  • the second layer of tipping paper is air impermeable, circumscribes the first layer of tipping paper, and extends from the mouth end of the filter to the rod end of the first layer of tipping paper.
  • the second layer has a circumferentially extending row of closely spaced perforations intermediate its two ends.
  • the mouth end portion of the second layer is attached to the underlying first layer of tipping paper.
  • the rod end portion of the second layer is freed by rotating this portion about the axis of the cigarette to break the perforations, thus forming a sleeve which can move axially between the mouth end portion of the second layer and positions along the tobacco rod.
  • the mouth end portion of the second layer prevents the sleeve from being removed from the mouth end of the cigarette.
  • the cigarette of the present invention is provided either with an axially retained rotatable sleeve or an axially retained rotatable filter plug with adjustably occludable openings for inter-mixing air with the smoke.
  • the degree of dilution is controlled by the size of the openings, that is, the degree to which the two sets of openings are in registry.
  • the method of the present invention is such that the cigarette may be readily produced on conventional cigarette making equipment and the tipping apparatus with a minimum of modification. Forming and cutting the cigarette rod and forming and cutting the filter plug, when included, to length are done conventionally. Also, bringing the filter plug into axial alignment with the cigarette rod and the overwrapping with tipping paper are accomplished in the same manner as in conventional cigarettes.
  • a means for permitting the smoker to select the specific smoke to air dilution ration desired may be provided through indicia (72 and 73 in Fig. 18, for example) which are printed on the tipping paper during the passage of the cigarette through the tipping apparatus. Such indicia are made readily visible and are designed to show the degree of registry of the openings.
  • Figs. 1, 2, and 3 One preferred embodiment of the present invention is shown in Figs. 1, 2, and 3 and comprises a tobacco rod 1 which is aligned with and joined to a conventional, substantially cylindrical filter plug 8, which may be cellulose acetate filter or the like.
  • the filter plug is wrapped by a substantially air impermeable plug wrap 7 which has openings 9 therein.
  • the filter plug 8 is joined to the tobacco rod 1 by tipping paper 2 which comprises a first band 5, a second band 4, and a third band 3.
  • the second band 4 contains openings 6 which are aligned with the openings 9 in the plug wrap.
  • Band 3 and band 5 are attached to the plug wrap and band 4 is freely rotatable about the longitudinal axis of the filter plug.
  • band 4 As band 4 is rotated, the openings 6 are brought into varying degrees of registry with the openings 9 in the underlying plug wrap. Thus the amount of air entering the filter, which it is mixed with the smoke produced by the burning tobacco 10, can be selected by adjusting the degree to which the openings 6 and 9 are in registry. Band 4 is retained against axial movement by bands 3 and 5 and this, in conjunection with the frictional resistance to rotation, insures that the degree of dilution, once selected, is maintained.
  • This rotatable sleeve embodiment may be readily manufactured employing conventional equipment. As shown in Fig. 4, a length of tipping paper is divided into banks 11, 12 and 13 by the two parallel rows of closely spaced perforations 14 and 15. These perforations may be made by any conventional means such as laser perforation, electrostatic perforation, or mechanical perforation using points or knives. It is preferred to employ a laser perforation device in order to make the perforations extremely small and minimize the possibility of even a slight axial slip in the assembled cigarette.
  • the tipping paper is fed through a perforating zone where it is exposed to at least a pair of laser light beams focused laterally of the width of the travelling tipping paper so as to define the desired width of the rotatable sleeve.
  • the power settings and focusing of the laser and the rate of feed of the tipping paper are selected so as to all but part the paper along the "break away" lines shown in Fig. 4.
  • the attachment which remains is selected to retain only enough strength to hold the bands together during assembly.
  • a laser system is employed to make about 100 perforations per inch in the paper.
  • the perforated tipping paper is applied to the cigarette in a conventional cigarette making machine in which a filter is positioned between two tobacco rods, as in Fig. 8.
  • the modification required in order to make the embodiments of the present invention using this conventional equipment is minor in that the adhesive applicator is adapted to provide a ribbon or the like of adhesive which, with reference to Fig. 8, is provided only along strips 3, 5, 19, and 21.
  • This tipping paper is wrapped around the two cigarette rods and intermediate filter, then the openings are made in the tipping paper and the underlying plug wrap using conventional equipment and then the tipping paper and filter are severed through the center of the filter to form two filter cigarettes.
  • a laser perforation system which uses a laser 23 to generate a laser beam that is passed through an initial focusing lens 24, then divided by beam splitter 25 with one half of the beam passing through lens 27 and being focused on the tipping paper to form opening 6 while the second half of the beam is reflected by mirror 26 through lens 28 which focuses the second beam onto the tipping paper to form opening 22.
  • the laser beam is focused to traverse the rotating cigarette and is set to remain on for a time period sufficient to make a slit of a desired length through the tipping paper and the underlying plug wrap. Slits one millimeter wide are preferred. If it is desired to establish a line of perforations instead of slits, the laser beam may be pulsed a given number of times to provide a line of separate holes.
  • the filter is severed at line 29 to form two cigarettes.
  • the cigarettes may then be passed to a drag breakdown device, such as is shown in Figs. 5 and 6, which employs rotating conveyor belts or rollers 16 and 17 and a skid plate 18.
  • a drag breakdown device such as is shown in Figs. 5 and 6, which employs rotating conveyor belts or rollers 16 and 17 and a skid plate 18.
  • an assembled cigarette is passed between rollers 16 and 17 and is aligned such that the middle band 4 of the tipping paper contacts a skid plate 18 which breaks the perforations in the tipping paper and frees band 4 for rotation about the longitudinal axis of the filter plug.
  • the rates of rotation of conveyors 16 and 17 may be adjusted such that a preselected degree of rotation of band 4 occurs during breakage of the perforations and so that the cigarettes exiting the breakdown device are set at a uniform diluting value.
  • Another view of this breakdown device is shown in Fig. 7.
  • the openings in the tipping paper and the underlying plug wrap may also be made by mechanical means as shown in Figs. 9, 10, 11 and 13.
  • cigarettes 37 are passed between rotating drums 35 and 36 which feed the cigarettes beneath a fixed plate 30 and into contact with a rotating perforation device comprising rotating wheels 31 and 33, which, as shown in greater detail in Fig. 13, are rotatably mounted on shaft 48, and have pin-like projections 32 and 34 which penetrate the tipping paper and plug wrap and also penetrate a short distance within the filter.
  • a device equivalent in function to that shown in Fig. 9 which employs a fixed plate 38, a rotating drum 41, and sets of teeth-like. projections 39 and 40 which are employed to perforate the tipping paper and plug wrap of cigarettes 42.
  • Fig. 11 which also employs a fixed plate 43 and a rotating drum 46 and has knife-like projections 44 and 45 which make slits through the tipping paper and plug wrap of cigarettes 47.
  • Very thin blades or finely pointed elements are used so that the vents are made to appear virtually invisible to the naked eye when observed by the smoker.
  • One millimeter wide slits are preferred.
  • Fig. 12 is a partial cross-sectional view taken through the openings in the tipping paper and the plug wrap.
  • opening 6 in the tipping paper 2 may be rotated into varying degrees of registry with opening 9 in the plug wrap 7 to permit varying amounts of air to enter through the two openings and into the filter mateial 8.
  • Rotation of band 4 in Fig. 2 will move opening 6 relative to opening 9 thus varying the degree of registry and the amount of dilution.
  • the tipping paper 2 and the plug wrap 7 are in close contact thus providing a frictional resistance to rotation which ensures that the degree of registry, once selected, S will be.maintained.
  • a second preferred embodiment of the present invention is shown in Figs. 14, 15 and 16 and again comprises a tobacco rod 49 which is axially aligned with and joined to a filter 58 by tipping paper 50.
  • the filter 58 is wrapped with a plug wrap 57 which has openings 59 therein.
  • the plug wrap is wrapped with a tipping- like paper 56 comprising three bands 52, 53 and 54 and having openings 55 therein.
  • This twice wrapped filter 58 is then joined to the tobacco rod 49 by tipping paper 50 having an opening 51 therein.
  • the filter extends beyond the tipping paper 50 to provide a stub which may be manipulated by the smoker to adjust the degree of dilution.
  • the intermediate layer 56 is preferably the same paper as layer 50 in order to present a uniform appearance to the smoker.
  • paper 56 may be eliminated and the plug wrap 57 may comprise three abutting bands corresponding to 52, 53 and 54 in Fig. 14. The following description will be understood to include this embodiment in whcih the intermediate wrapping is eliminated.
  • the paper 56 is attached to the plug wrap 57 such that openings 55 and 59 are in registry.
  • Band 53 is freely rotatable about the longitudinal axis of the plug member while bands 52 and 54 are attached to the plug member.
  • the filter plug with its wrapping 56 is then joined to the tobacco rod 49 by tipping paper 50 by attaching band 53 to the inner surface of the tipping paper.
  • Openings 51 are positioned above the underlying openings 55 and 59 such that as the filter 58 is rotated, the openings 55 and 59 are brought into varying degrees of registry with the openings 51 thus selecting the amount of air which can enter the filter and combine with the smoke for the burning tobacco 60 to produce a specific air dilution value.
  • band 53 is attached to the inner surface of the tipping paper and since bands 52 and 54 are attached to the plug wrap, the filter plus is freely rotatable within the cylinder formed by the tipping paper and yet is retained against axial movement. This, in conjunction with the frictional interaction of the paper 56 with the tipping paper 50, ensures that once a particular dilution value is selected it will be maintained.
  • the cigarettes of this rotatable plug embodiment are manufactured substantially as set for above for the rotatable sleeve embodiment.
  • an intermediate tipping paper layer is desired to be added, it is perforated, preferably using a laser system as set for above, and is then attached to the plug wrap, preferably with glue.
  • Conventional equipment is again employed and modified such that the glue applicator will apply glue only to the plug wrap side of bands 52 and 54.
  • a glue applicator is also modified such that the glue is applied to the plug side of the tipping paper 50 only on those portions which will contact the tobacco rod 49 and the sleeve 53. Otherwise, the manufacture of this second embodiment is substantially the same as the first.
  • the openings through the outer tipping paper, the inner tipping paper or other such intermediate wrapping, and the plug wrap at the same time using the laser perforation system as shown in Fig. 8 although one of the mechanical systems shown in Figs. 9, 10 and 11 may also be employed.
  • the assembled cigarettes are then passed through a drag breakdown devivce as described with reference to Figs. 5, 6 and 7, but alignment of the cigarettes within the device is altered as shown in Fig. 17 such that the protruding end of the filter plug contacts the drag plate thereby breaking the perforations in the inner layer of tipping paper; thus permitting the filter plug to freely rotate within the outer cylinder of tipping paper while being axially retained therein.
  • a third preferred embodiment of the present invention is shown in Fig. 18 and comprises a tobacco rod 64 comprising a column of tobacco 68 circumscribed by a substantially air impermeable wrapping 65, which is preferably cigarette paper, which is circumscribed adjacent the mouth end by an outer cylindrical layer 70 of substantially air impermeable tipping paper extending from the mouth end to a point between the • mouth end and the middle of the tobacco column.
