Definitions

  • a smoke controlling vdevice in the form of a sleeve which is slidable and rotatable on a cigarette, and provided with a hollow longitudinal rib for the passage of auxiliary air either into the users mouth or entranied with the smoke.
  • the cigarette is punctured and preferably a cavity is provided within a filler unit contained in the cigarette.
  • main stream smoke contains less harmful compounds, than during the intervening periods of minimal flow when the so-called side stream smoke is produced. This is due to the smaller percentage of air in the side stream smoke.
  • a further factor is the accumulation of the injurious products in the unburned tobacco behind the ember through which the smoke is drawn, as well as the recombustion of these compounds as the cigarette is consumed.
  • the purpose of the present invention is to minimize the harmful effects of tobacco smoking, and accordingly, the objects of this invention include:
  • a smoke control means for cigarettes wherein the cigarette is modified to increase sleeve expands for free sliding movement on the cigarette, said sleeve being adapted to perform such functions, Vas heat dissipation, and air and smoke liow control, as well as functioning as a holder.
  • FIGURE l is a side view of a cigarette, modified to incorporate the smoke control means.
  • FIGURE 2 is a fragmentary view of a cigarette and its control means as it appears during smoking of the cigarette.
  • FIGURE 3 is an enlarged sectional view taken within circle 3 of FIGURE l.
  • FIGURE 4 is an enlarged transverse sectional view taken through 4-4 of FIGURE 1 showing the air and smoke control sleeve in its cigarette gripping condition.
  • FIGURE 5 is a similar sectional view showing the manner in which the sleeve is distorted in order to expand it so as to permit free movement of the sleeve on the cigarette.
  • FIGURE 6 is an enlarged fragmentary sectional view showing a modied form of heat absorbing means.
  • FIGURE 7 is an enlarged fragmentary sectional view taken through 7-7 of FIGURE l, showing the filter end of the cigarette.
  • FIGURE 8 is an enlarged sectional view similar to FIGURE 7 showing a Imodified filter construction.
  • FIGURE 9 is a fragmentary side view, showing a filtertip type of cigarette and illustrating the function of the air and smoke controlling sleeve.
  • FIGURE l0 is a diagrammatical, transverse view of the sleeve only, corresponding to FIGURE 4, showing two hollow ribs.
  • FIGURES 1 through 5 The cigarette designated 1, herein illustrated, is modified by the provision of a plurality of transverse air passages 2, preferably, but not necessarily, arranged in a common plane and equally spaced.
  • the transverse air passages occupy that portion of the cigarette which is normally smoked.
  • the total number of passages and the cumulative area of these passages is such that it would be difficult to smoke the cigarette.
  • a sleeve 3 is provided on one side of which is formed a hollow rib 4.
  • the sleeve is preferably provided with an internal metal liner 5 which may be formed of metal foil.
  • the liner or foil is covered with a insulation coating or lamination 6.
  • the dimensions of the sleeve are such that it tends to grip the cigarette and is not readily slidable thereon, however, by reason ofthe hollow rib 4, the sleeve may be compressed in a diametrical plane passing through the sleeve; that is, the sleeve may be compressed in the direction of the arrows, shown in FIGURE 5, so as to effect a slight expansion of the sleeve to permit ready movement of the sleeve either longitudinally or rotationally.
  • the hollow rib forms with the confronting portion of the cigarette 1, a duct 7. If the sleeve is rotated, as indicated by the dotted lines in FIGURE 4, air passages 2 may be exposed or partly exposed to the duct 7.
  • a heat conducting arm 8 Extending from one end of the sleeve 3 and forming a continuation of or secured to the metal liner 5 is a heat conducting arm 8 which arches forwardly terminating in spaced relation to the cigarette 1.
  • the extremity of the arm 8 is provided with a pin 9 formed of heat conducting material whichextends axially into the cigarette.
  • the heat absorbing pin 9 When the cigarette is ignited, the heat absorbing pin 9 extends through the cigarette ember 10 and conducts heat from the ember to the arm 8. Some of the heat received by the pin is radiated by the arm 8. The remaining heat is carried to the sleeve 3 and particularly, the metal liner 5. The residual heat in the liner 5 is transferred to air fiowing through the hollow rib 4.
  • the sleeve be moved backward along the cigarette as the cigarette is consumed.
  • the coating or lamination 6 on the sleeve 3 is, of course, formed of non-inflammable material. If the sleeve is not moved backward, the sleeve will tend to smother the ember when the ember reaches and enters the sleeve. This feature of the sleeve serves to minimize the burning of an unattended cigarette and materially reduces the fire hazard.
  • FIGURE 6 illustrates a modified form of heat absorbing means.
  • Each air passage receives a wire 12 which absorbs heat from the ember 10 and is itself partially cooled by air flow in the passage.
  • the wires may be corrugated as indicated by 13 or otherwise Iformed so as to be retained in the air passages, or several wires may be twisted together, Still further, one or both extremities of each wire may be extended along the surface of the cigarette as indicated by 13a for heat transferring contact with the metal liner 5 of the sleeve 3.
  • the first described sleeve 3, with the arm 8 and pin 9 omitted, may be employed at the mouth-end of the cigarette.
  • the sleeve may serve as a holder or mouthpiece, and may also be employed to hold a filter unit 14, preferably in spaced relation to the cigarette, as indicated by the gap 15.
  • the filter unit includes a metallic shell 16 preferably formed of metal foil. The ends of the shell are inturned as indicated by 17 so as to retain a series of lfilter elements. Beginning at the extended end of the filter unit, there is provided a non-metallic filter 18 formed of cellulose acetate or cotton fibers. Contiguous to the non-metallic filter is a metallic filter 19 formed of heat conductive filaments, such as copper filaments. Contiguous to the filter 19 is a charcoal filter 20, which is separated from a second non-metallic filter 18, by an air space 21 ⁇ In this region, the shell 16 is provided with perforations 22. Continuing towards the mouth-end of the filter there is provided a second metallic filter 19. At the mouth-end of the 4 lfilter, there is provided a fiavor disk 23 which may contain menthol.
  • the filter unit 14 is axially slidable in the sleeve 3, particularly as the sleeve is distorted as shown in FIG- URE 5 and the filter unit 14 may be rotated to bring one or more of the perforations 22 into registry with the hollow rib 4 so as to control the flow of air and its mixture with the tobacco smoke in the same manner as was referred to relative to FIGURE 4.
  • the gap 15 also serves a similar purpose. In both cases, some smoke may enter the air stream in the duct 7, but also, auxiliary air will enter the smoke stream.
  • the filter unit may be constructed so as to be received between the lips of the user or may be wholly within the sleeve 3, in which case the sleeve 3 forms a mouthpiece.
  • FIGURE 8 illustrates a modified filter unit 24.
  • the filter unit 24 is provided with a metallic shell 16 in the nature of the filter unit 14.
  • the filter unit 24 is filled with a lmixture of metal fibers 25 and charcoal granules 26.
  • the ends are closed by non-metallic filters 27 similar to the filters 18.
  • the filter units 14 and 24 are rendered particularly effective due to the fact that most of the harmful products are removed before the smoke enters the filters so that in effect, the efficiency of the filters is increased.
  • the cigarette 1 is provided with a filter tip 28 which may be a conventional filter tip except for the fact that it is provided with transverse air passages 29.
  • a sleeve 3 is employed principally as a mouthpiece, but also as a means of controlling flow of air of the passages 29. This is accomplished by rotating the sleeve 3 in the manner illustrated in FIGURE 4. By rotating the sleeve, and increasing or decreasing ⁇ the entrained air, the cigarette smoke may be cooled to the desired degree.
  • the cigarette shown in FIGURE 9 may have a series of transverse air passages 30 of smaller diameter than the air passages 2 so as to admit a controlled amount of air.
  • the smoke controlling means is particularly adapted for cigarettes, it may be adapted to tobacco smoked in other forms; for example, cigars.
  • a smoke control means for cigarettes comprising:
  • v (a) a sleeve unit dimensioned to fit a cigarette for longitudinal movement thereon;
  • said sleeve unit having at least one hollow rib extending longitudinally from end to end whereby, when said sleeve unit is fitted on a cigarette, at least one passageway for air is formed externally of the cigarette.
  • a smoke control means as defined in claim 1, where- (a) said sleeve unit is yieldable to compression forces applied in the plane passing through the axis of said sleeve unit and said hollow rib to expand in effective diameter, thereby to slip freely on the cigarette.
  • a smoke control means as defined in claim 1, wherein:
  • said sleeve unit has an inner conductive lamination and an outer lamination of heat insulating material.
  • a smoke control means as defined in claim 1, where- (a) said sleeve is flared at, at least, one end.
  • said sleeve unit having at least one hollow rib extending longitudinally between the ends of said sleeve unit and forming with the cigarette an air passage, said air passage adapted, by adjustment of said sleeve unit, to be aligned with selected transverse passages for controlling the flow of air and smoke to the mouth of the user.
  • said cigarette has a filter at one end, said filter defining at least one wall of a cavity within said cigarette having a side perforation for radial flow of air and smoke;
  • said means being adapted for positioning over said filter and partially received in the mouth of the user whereby, when aligned with said side perforation, air drawn through said hollow rib is entrained with smoke from the cigarette.
  • a cigarette and smoke control means therefor comprising:
  • said sleeve unit having at least one longitudinal hollow rib forming with said wrapping an air passage;
  • said sleeve unit being expansible upon compressive force on said rib to facilitate movement of said sleeve unit on said wrapping to bring said passage and side perforation into registry.
  • said filter unit includes a metallic shell and heat conductive elements, heat absorbing elements and charcoal filter elements within said shell.
  • a smoke diluting means comprising:
  • said smoke diluting means is a sleeve slidably fitting said cigarette, one end being received in the users mouth, the opposing end defining said inlet, and said duct being defined in part by said sleeve and in part by the wrapping of the cigarette, whereby said auxliary air moves externally of said labyrinth passage into the users mouth.
