Definitions

  • This invention relates to reduced ignition propensity cigarettes.
  • the invention relates to cigarettes containing burn retardant zones, as well as to methods for manufacturing such a cigarette.
  • a cigarette is broadly defined as a roll of tobacco capable of being smoked as it is and which is not a cigar or cigarillo; a roll of tobacco which, by simple non-industrial handling, is inserted into a cigarette-paper tube; or a roll of tobacco which, by simple non-industrial handling, is wrapped in cigarette paper.
  • Cigarettes. and methods for their manufacture are widely known.
  • a problem currently experienced with most conventional cigarettes is that they are not self-extinguishing. In other words, once lit, most cigarettes can continue burning through their entire length without having to be actively smoked.
  • This self sustained burning is generally obtained by impregnating the cigarette paper surrounding the tobacco roll with a burn accelerant such as sodium citrate. While the self-sustained burning alleviates the need for smokers to constantly re-light their cigarettes, as well as increase cigarette consumption, it also creates a substantial fire hazard if burning cigarettes are left unattended. In essence, the length of time a cigarette bums after having been left unattended is directly proportionate to the amount of fire risk it poses.
  • United States patent number 4,483,349 entitled “Filter Cigarette Making Machine” in the name of Molins Limited discloses a cigarette filter attachment machine which includes a fluted drum which is arranged to receive double filters and double tobacco rods. A knife cuts the double tobacco rods through the middle to form separate tobacco rod portions and, with the aid of a further drum, the two portions associated with each double filter are swopped in position so as to lie at opposite ends of the double filter, displacement of one of the tobacco rod portions being achieved preferably by displacing the associated double filter which in turn pushes the tobacco rod portion.
  • the double tobacco rods may be delivered axially into the flutes of the first drum from a cigarette making machine, preferably after delivery of the double filters which can then serve as resilient buffers for the incoming double tobacco rods.
  • the machine disclosed in Molins has been used extensively in cigarette production and, to the applicant's knowledge, is still being used today. It should be appreciated that the machine produces filtered cigarettes from double tobacco rods so that, after the double tobacco rods have been cut into cigarette portions and the filters attached, the cut ends are positioned at the non-filtered ends thus providing cigarettes with neatly cut ends.
  • the machine also provides a way of swopping the positions of two separate filtered cigarettes or cigarette portions that are positions end- to-end.
  • Machines capable of performing the functions of Molins and for making cigarettes in general are, however, expensive. It can therefore be assumed that machines capable of manufacturing cigarettes in accordance with the current invention will likewise be very expensive to manufacture from scratch. If reduced ignition propensity cigarettes in accordance with the current invention are therefore to be manufactured it would be beneficial if currently available machines could be inexpensively adapted for this purpose.
  • tobacco roll will refer to a roll of tobacco of an undefined length.
  • a “cigarette rod”, in turn, will refer to a tobacco roll which is wrapped in smoking paper.
  • a reduced ignition propensity cigarette comprising a paper body containing a tobacco roll, the cigarette being characterized in that a zone exists in the tobacco roll intermediate its ends through which tobacco strands do not pass but are generally in abutment, and in that a bum retarding band extends at least partially about the zone.
  • a further feature of the invention provides for the tobacco roll to be at least partially severed in a direction substantially transverse to its major axis intermediate its ends to form the zone, thus yielding two tobacco sections positioned in end-to-end abutment, alternatively, for it to be completely severed in a direction substantially transverse to its major axis intermediate its ends to form a zone with no tobacco strands passing therethrough.
  • the tobacco roll to include more than one zone and a burn retarding band extending at least partially about each such zone; for the tobacco roll to be at least partially severed in a direction substantially transverse to its major axis intermediate its ends to form each- zone, thus yielding, more than two tobacco sections positioned in end-to-end abutment; for the cigarette to have a filter attached co-axially with the body at an end thereof, alternatively for it to include two filters attached co-axially with the body, one at each end thereof; and for the burn retardant band to comprise a band of smoking paper which is substantially free of burn accelerant.
  • the reduced ignition propensity cigarette to comprise two abutting, co-axially aligned separate cigarette rod sections joined end-to-end by means of a burn retardant band; for the burn retardant band to be a strip of smoking paper; for the strip of smoking paper to be substantially free of burn accelerant extending at least partially about the joined ends of the cigarette rod sections; for the cigarette to include at least one additional bum retardant band extending at least partially about a cigarette rod section intermediate its ends; for each cigarette rod section to comprise a cylindrical paper body containing a tobacco roll with a zone existing in each tobacco roll intermediate its ends through which tobacco strands do not pass but are generally in abutment with a burn retarding band extending at least partially about each zone; and for the zone to be created by conventional cutting, laser cutting or the like.
  • the invention further provides a method of manufacturing a reduced ignition propensity cigarette comprising the steps of
  • steps (b) and (c) to be reversible; and for steps (b) and (c) to be performed together by laying down a burn retardant band on the piece of smoking paper and then wrapping the smoking paper about the tobacco roll so that the burn retardant band extends at least partly about the zone.

  • the invention still further provides a method of manufacturing a reduced ignition propensity cigarette comprising the steps of aligning two or more cigarette rod sections end-to-end to form a zone between them through which tobacco strands do not pass but are generally in abutment and joining the aligned ends of the cigarette portions with a burn retardant band.
  • the invention yet further provides a method of manufacturing a reduced ignition propensity cigarette comprising the steps of cutting a double length cigarette rod into two cigarette rod sections; swopping the positions of the cigarette rod sections soJhat they are-co-axially aligned with their cut ends directed away from each other; inserting a double length filter between the swopped cigarette rod sections; wrapping the double length filter and the ends of the cigarette rod sections adjacent the double length filter with tipping paper to create a double filtered double cigarette; and cutting the double filtered double cigarette midway along the double length filter to form two filtered cigarettes; the method being characterized in that it includes the steps of swopping the positions of the filtered cigarettes so that they are co-axially aligned with their non-filtered ends adjacent one another and joining the adjacent non-filtered ends of the filtered cigarettes with a burn retarding band.
  • the method to include the step of creating a line of weakness across the burn retarding band so that, after joining the adjacent non-filtered ends of the filtered cigarettes, the line of weakness is aligned with the joined non-filtered ends, thereby allowing the cigarette to be broken into two, individually smokable cigarettes; and the step of wrapping at least one additional burn retarding band about the cigarette rod, intermediate its ends.

  • Figure 6 illustrates the sequence of events occurring during the manufacture of the cigarette of Figure 5 in accordance with an alternative method of the invention.
  • a reduced ignition propensity cigarette (2) comprises a paper body (4) containing a tobacco roll (6).
  • the tobacco roil will generally have been cut from a longer, continuous roll that comprises numerous tobacco strands rolled together into a roll with the strands interweavingjn- substantially all directions.
  • a substantial portion of the strands also extend in a direction generally along the major axis of the roll.
  • the tobacco roll (6) includes a zone (8) intermediate its ends (10), through which substantially no tobacco strands pass.
  • the strands are, however, in abutment on either side of the zone (8).
  • the zone (8) extends substantially transverse to the major axis (12) of the cigarette (2) thus yielding two sections (14, 16) of tobacco positioned in end - to - end abutment.
  • a burn retardant band (18) extends around the cigarette (2) and over the zone (8).
  • the burn retardant band (18) is a strip of smoking paper which is substantially free of burn accelerant.
  • the cigarette and tobacco will burn along the length of the cigarette towards the filter. This is mainly due the burn accelerant present in the smoking paper.
  • the burn retardant band (18) it will be retarded, the burn accelerant in the smoking paper (4) underneath the band (18) in combination with the smouldering tobacco strands may, however, still promote burn, albeit slower, towards the filter.
  • the burn retarding band (18) and zone (8) will prevent the cigarette from burning past the zone (8). It should be appreciated that the lack of tobacco strands passing through the zone (8) implies that smouldering strands will die out at the zone (8).
  • the zone (8) in the tobacco roll (6) may only be a partial cut through it. Such a partial cut may in some cases be sufficient to prevent burning across the zone (8) and the cigarette (2) will extinguish at the zone (8) if not smoked.
  • the cigarette (30) includes a cigarette rod (32) (a cylindrical paper body containing a tobacco roll) and one cigarette filter (34) connected co-axially with the rod (32) at an end (36) thereof.
  • the cigarette rod has three separate sections (38), abutting end-to-end in two zones (40) between the ends (36) of the cigarette (30).
  • a burn retardant band (42) in the form of a strip of smoking paper which is substantially free of burn accelerant, is wrapped around each pair of abutting ends of the cigarette rod sections (38) to join them together.
  • the cigarette (30) may therefore be smoked all the way through if a smoker continually draws on it, particularly when the burn reaches the zones (40), or may be left alone in which case it will self-extinguish at the next zone (40).
  • FIG. 4 Steps involved in a method of manufacturing a reduced ignition propensity cigarette as shown in Figure 3 are illustrated in Figure 4. It should be appreciated that even thought the cigarette of Figure 3 is shown without a filter in Figure 4, filters may be added to the cigarette shown by conventional methods at one or both ends of the cigarette.
  • a cigarette rod (60) is shown at a stage (A).
  • the cutting of the cigarette rod could be achieved by any standard means such as by means of a blade or laser. It is also foreseeable that the cut may be achieved by means of a pulsing laser after the tobacco roll has been wrapped in the paper body, in which case the zone will not be continuous, but will be a series of spaces apart linear zones. In the latter case the tobacco would be at least partly cut although some tobacco strands may still span between the cigarette rod sections. It should also be appreciated that there is no limit to the number of cuts that can be made through the cigarette rod and that any number of cigarette rod sections may subsequently be rebound, thus allowing for a reduced ignition propensity cigarette having any number of extinguishing zones.
  • the cuts through the cigarette rod may also be made only partly therethrough. In which case the tobacco strands will be completely severed in a portion of the rod and spanning between the sections in another portion. Such a partial cut, while still resulting in self-extinguishing of the cigarette, may allow for greater rigidity of the cigarette and may also ensure a more uniform dropping of burnt cigarette ash.

  • a double length cigarette rod (82) is cut into two separate cigarette rod sections (84) by means of a cutting mechanism (not shown) along a cutting line (86).
  • the positions of the cigarette rod sections (84) are then swopped at a stage (B), so that they are again aligned co-axially with their cut ends (88) directed away from each other.
  • the tobacco rod portions are then separated at a stage (C) and a double length filter rod (90) is inserted between the cigarette rod sections (84).
  • the cigarette rod sections (84) and double filter rod (90) should be next to each other with little or no gaps between the various parts.
  • the double filter rod (90) and the ends of the cigarette rod sections next to it are then wrapped with tipping paper (92) at a stage (D) so as to join the double filter and the ends of the cigarette rod sections together.
  • tipping paper As is common practice in the industry, glue is applied to at least one end region of the tipping paper before the tipping paper is wrapped around the double filter and ends of the cigarette rod sections and glued back onto itself.
  • the cigarette rod section/double filter/cigarette rod section combination at this stage forms a double filtered double cigarette (94).
  • the double filtered double cigarette (94) is then cut into two separate, filtered cigarettes (96) at a stage (E).
