Abstract
Description
- The present invention relates to filter cigarettes. More particularly, the present invention relates to filter cigarettes which are adjustable.
- Various mechanisms have been disclosed in heretofore issued patents which provide for adjustment of the air dilution value of a filter cigarette, but these mechanisms are not without certain disadvantages. While many complicated mechanisms have been disclosed, the simpler mechanisms generally involve making one or more openings through a substantially air impermeable filter plug wrap and the overlying, substantially air impermeable tipping paper and one or more corresponding openings in a sleeve which is placed over the tipping paper and which is then either rotated or moved axially to select the degree to which the two sets of openings are in registry. In another embodiment found in the art, the filter is not glued to the tipping paper and thus may be moved axially within the cylinder formed by the tipping paper. Openings are made in the filter plug wrap and corresponding open-- ings are made in the tipping paper. The air dilution value is adjusted by axially moving the filter plug within the tipping paper to adjust the degree to which the two sets of openings are in registry.
- Among the problems associated with such mechanisms are that 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.
- Accordingly, it is an object of the present invention to provide a cigarette which can be readily manufactured on conventional cigarette making equipment and that is adjustable to vary the ratio of air to smoke delivered to the mouth of the smoker.
- According to the invention, there is provided a filter cigarette comprising a tobacco rod, a wrapped, substantially cylindrical, filter plug comprising: a first mouth-end segment and a second axially aligned, rod-end segment spaced apart from the first segment; means joining the tobacco rod to the second segment in axially aligned, abutting end-to-end relation; and substantially air impermeable tipping paper, the wrapping being substantially air impermeable and defining a substantially cylindrical void between the first segment and the second segment, and the tipping paper circumscribing the filter plug and the mouth end of the tobacco rod, the first segment being movable along the longitudinal axis of the cigarette towards the second segment, whereby the plug wrap between the first segment and the second segment is compressed (FR-A-2273443), varying the resistance to draw of the cigarette characteristised in that there are a first opening in the tipping paper and a second opening in the underlying plug wrap positioned such that as the first segment is moved axially towards the second segment, the first and second openings are moved into varying degrees of registry, thereby admitting varying amounts of air to the filter, changing the air dilution value of the cigarette. The compression of the plug wrap between the first and second segments increases the resistance to draw of the filter, whilst the increase in air dilution decreases the resistance to draw.
- Cigarettes of the invention are adjustable to provide a wide range of air dilution and resistance-to-draw values and may include means for releasing varying amounts of a flavourant. The air dilution value is the ratio of the volume of air to the volume of smoke exiting the mouth end of the filter, expressed as a percentage.
- The invention will now be further described, by way of example, with reference to the drawings, in which:
- Fig. 1 is an enlarged, partially fragmentary perspective view, taken from the mouth end, of a first preferred embodiment of the filter cigarette of the present invention;
- Fig. 2 is an enlarged perspective view, taken from the mouth end, of the assembled embodiment of Fig. 1;
- Fig. 3 is a cross-sectional view taken along the line A-A of Fig. 2;
- Fig. 4 is an enlarged, partially fragmentary perspective view, taken from the mouth end, of a second preferred embodiment of the filter cigarette of the present invention;
- Fig. 5 is an enlarged perspective view, taken from the mouth end, of the assembled embodiment of Fig. 4;
- Fig. 6 is a cross-sectional view taken along the line B-B of Fig. 5;
- Fig. 7 is an enlarged, partially fragmentary perspective view, taken from the mouth end, of a third preferred embodiment of the filter cigarette of the present invention;
- Fig. 8 is an enlarged perspective view, taken from the mouth end, of the assembled embodiment of Fig. 7;
- Fig. 9 is a cross-sectional view taken along the line C-C of Fig. 8;
- Fig. 10 is a view similar to Fig. 9 and showing the first segment moved to a position towards the second segment at which the openings in the tipping paper are in registry with the openings in the plug wrap; and
- Fig. 11 is a view similar to Fig. 9 but showing a flavour generator positioned in the void between the first and second segments.
- Common to the preferred embodiments of the present invention are the following elements: a
tobacco rod 1 comprising a substantially cylindrical charge oftobacco 13 is enclosed incigarette paper 15 and is axially aligned with a filter plug comprising afirst filter segment 7 and a second filter segment 3. Means are provided joining thetobacco rod 1 to the second segment 3 in abutting end-to-end relation at the line ofabutment 5. The first and second segments are spaced apart and are joined by acircumscribing wrapping 9 which is substantially air impermeable. This wrapping initially defines a substantially cylindrical void between the first and second segments. The tippingpaper 11, which is substantially air impermeable, circumscribes the filter plug and the mouth end of the tobacco rod. The tipping paper extends from a position intermediate the ends of the first segment to a position on thetobacco rod 1 adjacent the rod end of the second segment 3. - A first opening is provided in the tipping paper and a second opening is provided in the underlying plug wrap. The
first segment 7 is movable along the longitudinal axis of the cigarette towards the second segment 3 either by rotation or by translation. Movement along this axis compresses the plug wrap between the segments thereby decreasing the volume of thevoid 8 which varies the resistance to draw to provide a constant resistance to draw value. - The cigarette of the present invention, as shown in Fig. 11, may optionally include a
flavour generator 43 in thevoid 8 which is designed to release increasing amounts of a flavourant within the void responsive to movement of thefirst segment 7 towards the second segment 3. As a flavour generator, an encapsulation system may be employed, such as strips of cellophane containing discrete reservoirs of one or more flavourants which are designed to burst responsive to the pressure exerted by movement of the first segment towards the second segment. Other equivalent flavour generators which will occur to those skilled in the art may also be employed. - If desired, the first and second openings may be omitted resulting in a filter cigarette which has a variable resistance to draw. This variable resistance to draw embodiment may optionally include a flavour generator.
- In a first preferred embodiment shown in Figs. 1 to 3,
bands Band 16 extends from the mouth end of thefirst segment 7 up to the rod end of the first segment and is attached to theunderlying plug wrap 9.Band 18 extends from a position on thetobacco rod 1 adjacent the rod end of segment 3 up to the mouth end of segment 3.Band 18 is attached tocigarette paper 15 andplug wrap 9 and joins segment 3 to thetobacco rod 1. The tippingpaper 11 extends from the mouth end ofsegment 7 to a position on thetobacco rod 1 which corresponds to the position of the rod end ofband 18. At least oneopening 17 is provided in the tipping paper and at least oneopening 19 is provided through theband 18 and theunderlying plug wrap 9. The tippingpaper 11 is attached only toband 16 for movement therewith along the axis of the cigarette towards the coal end oftobacco rod 1. - In practice, the smoker moves the tipping
paper 11 axially towards the coal end of thetobacco rod 1 which movessegment 7 towards segment 3 compressing the plug wrap between the first and second segments thereby increasing the resistance to draw and varying the degree of registry between theopenings - The
openings first segment 7 towards the second segment 3 or theopenings first segment 7 towards the second segment 3. - The
band 18 joins thetobacco rod 1 to the segment 3, preferably by means of a band of adhesive 25-which overlaps the line ofabutment 5. The tipping paper is preferably attached to theunderlying band 16 by anadhesive material 21 and theband 16 is preferably attached to theunderlying plug wrap 9 by means of anadhesive material 23. - This embodiment, as well as those embodiments discussed below, may be fabricated using existing cigarette making equipment, which is commercially available and known to those skilled in the art, with only minor modifications. The openings in the tipping paper and the underlying layers may be made employing any conventional means such as electrostatic discharge apparatus, mechanical perforation apparatus, or a laser perforation system. The openings may be made either before or after assembly.
- In a second preferred embodiment shown in Figs. 4 to 6, the
tipping paper 11 extends as in the first embodiment but is attached directly to theplug wrap 9 over thefirst segment 7, preferably by means of a band ofadhesive material 39. Discrete areas ofadhesive material 37 are applied to the inner surface of the tippingpaper 11 at positions about the circumference of the inner surface of the tipping paper which overlie the plug wrap intermediate the rod end ofsegment 7 and the mouth end of segment 3 and define a plane which is perpendicular to the longitudinal axis of the cigarette. Afirst opening 33 is provided in thetipping paper 11 and asecond opening 35 is provided in the plug wrap overlying the segment 3. Theopenings - With one exception, this second embodiment operates as described for the first embodiment and may be modified in the same way as the first embodiment, the exception being that the discrete areas of
adhesive material 37 join the tipping paper to theplug wrap 9 such that the rod end of the tipping paper moves towards the mouth end of the cigarette responsive to movement of thefirst segment 7 towards the second segment 3. In the first embodiment, the entire length of tippingpaper 11 moves in the direction of movement of thefirst segment 7. This movement of the rod end of thetipping paper 11 is caused by compression of the plug wrap'9 overlying thevoid 8, which compression draws the tipping paper towards the longitudinal axis. - In a third preferred embodiment shown in Figs. 7 to 10, the tipping
paper 11 extends from a position intermediate the mouth end and rod end ofsegment 7 to a position ontobacco rod 1 adjacent the rod end of segment 3. The tipping paper is attached only to the plug wrap overlying segment 3 and to the cigarette paper adjacent the rod end of segment 3, thereby attaching thetobacco rod 1 to the second segment 3. Preferably, the means of attachment is a band of adhesive 31 which overlaps the line ofabutment 5. Afirst opening 27 is provided in the tippingpaper 11 and asecond opening 29 is provided in the plug wrap overlying thefirst segment 7 at a position intermediate the mouth end of the tippingpaper 11 and the rod end ofsegment 7. - In practice, the
first segment 7 is moved axially towards the second segment 3 either by a longitudinally acting force which may be applied by holding the cigarette rod and tapping the protruding end of thefirst segment 7, or by grasping the protruding end and rotating it. This movement compresses theplug wrap 9 which overlies thevoid 8 as shown in Fig. 10, thereby decreasing the volume of thevoid 8 and varying the resistance to draw value of the cigarette. This movement also varies the degree of registry of theopenings - It will be understood that the particular embodiments described are only illustrative of the principles of the present invention, and that various modifications can be made by those skilled in the art.
