Definitions
- This invention relates to cigarettes of the kind comprising a tobacco portion encased in paper, and a stub portion, joined together in abutting relation by a band that encircles at least a portion of both the tobacco portion and stub, and is adhesively secured thereto, to provide a composite cigarette. It also relates to cigars or cigarillos manufactured in a similar manner. Such cigarettes, cigars or cigarillos are hereinafter referred to as cigarettes of the kind described.
- a narrow strip of the encircling band coincides with the butt joint between the tobacco portion and the stub.
- said narrow strip is referred to as the line corresponding to the butt joint between the tobacco portion and stub.
- the stub portion may be constituted by any of the well known materials, e.g. crimped paper, cellulose acetate, tobacco, or a hollow mouthpiece, or a composite stub comprising say a section of activated charcoal and a section of crimped paper, and the stub or composite stub itself may be secured within a paper, or like, sheath.
- the present invention consists in a cigarette of the kind described, wherein the encircling band comprises a band of substantially impermeable material that is rendered highly permeable at an area or areas on or a continuous area along the line corresponding to the butt joint between the tobacco portion and stub of the composite cigarette, whereby air may be drawn in through said line, the volume of said air being controlled by the permeability of the band where it is highly permeable in conjunction with the extent of the periphery of the butt joint that is disposed behind said area or areas.
- the word areas has been used to indicate that the highly permeable portions are not mere pin-holes. This is an important aspect of the present invention since air will only enter at the line corresponding to the butt joint between the tobacco and stub portions, and, if the highly permeable portions were mere pin-holes, the placing of these would become critical.
- the present invention by utilizing permeable areas, allows for some degree of variance in the location of the permeable portions with respect to the butt joint line, and still provide a sufiicient area of the highly-permeable material to overlie the butt joint line to insure an adequate amount of air being taken in.
- the encircling band containing the highly-permeable areas may comprise a web of highly permeable material secured to a Web of less permeable material, the latter being perforated at one or more areas along the line corresponding to the butt joint between the tobacco portion and stub of the composite cigarette, thus rendering the band highly permeable at said area or areas whereby air may be drawn in through said line, the volume of said air being controlled by the permeability of the band at said area or areas in conjunction with the extent of the periphery of the butt joint that is disposed behind it or them.
- the web of less and highly permeable material may encircle the whole length of the stub.
- the web of less permeable material may encircle the whole length of the stub with the web of highly permeable material secured near one edge thereof so that the latter is secured only adjacent the perforations.
- the highly and less permeable material is secured to the cigarette and stub as a narrow band.
- the encircling band may comprise a band of substantially impermeable material that is rendered highly permeable at an area or areas on or a continuous area along the line corresponding to the butt joint between the tobacco portion and stub of the composite cigarette by thinning the material of the band at said area or areas.
- the material may be thinned by shaving material off a surface of the band.
- FIG. 1 shows a cigarette joined to a stub with an encircling band comprising a narrow web of highly permeable material secured to a narrow web of less permeable material.
- FIG. 2 shows a cigarette joined to a stub with an encircling band comprising a wide web of highly permeable material secured to a wide web of less permeable material.
- FIG. 3 shows a cigarette joined to a stub with an encircling band comprising a narrow web of highly permeable material secured along one edge of a wide web of less permeable material, said wide web extending to the end of the stub.
- FIGS. 1, 2 and 3 the composite webs of highly and less permeable materials are shown curled back in places to illustrate the construction.
- FIGS. 4 to 6 are examples of different patterns of perforations that may in some instances be preferred.
- the normal method of manufacturing a cigarette as shown is to roll two cigarettes, with an intervening double length stub, in a gummed double length encircling band, and then cut the stub through the encircling band at its mid point thus providing two single composite cigarettes each comprising a cigarette 1, a stub 2 and an encircling band 3.
- the stub may be ensheathed in its own paper sleeve 4.
- 5 is the butt joint between cigarette and stub.
- the encircling band for joining a stub and cigarette together is constructed in the following manner, so as to maintain control of air intake and tar reduction.
- a Web 3 of substantially impermeable paper for example the well known imitation cork tipping material, is apertured at one or more areas with circular perforations 6, e.g. perforations of about 2 mm, diameter spaced at a convenient distance apart so as to provide, say four perforations around the circumference of a cigarette at equal distances.
- the line on which the perforations are made is the line corresponding to the butt joint between the tobacco portion and stub, i.e. it is such that in the finished composite cigarette the perforations lie with their diameters coincident with the butt joint between the tobacco portion 1 and stub 2.
- a web of, say, cork tipping material is perforated as above described before slitting into widths suitable for joining two cigarettes together.
- the web may be wide enough to be subsequently slit into say fifteen double length encircling bands.
- This impermeable web is preferably pre-gummed with an adhesive that becomes tacky when moistened.
- the web thus perforated is then moistened and laminated to a similar web of highly permeable paper.
- the amount of air drawn in may be more readily varied with the use of highly permeable areas since the total amount of the highly permeable portions overlying the butt joint line can be more easily varied merely by shifting the areas. If pinholes were employed, a shift would probably remove all of the highly permeable material from communication with the butt joint line thus preventing any air from entering. Areas of different sizes and shapes can also provide these advantages as is explained below.
- a perforating machine that is to say a machine in which the paper web is moved between circular pegs carried in and protruding slightly from a rotating cylindrical arbor, and a high speed cylindrical cutting head that acts to shave oif material from the web coincident with the pegs.
- pegs shaped to produce perforations as illustrated in FIGS. 4 to 6, which for convenience can be referred to as lozenge shaped, may be used.
- FIG. 4 which shows a web of highly permeable paper 7 laminated to a web of lesser permeable paper 3, the perforations 6 are made by pegs which are 3 mm. diameter ground on both sides to provide two parallel flats 8 and 9, two mm. apart.
- perforations are then arranged around the cigarette parallel as shown in FIG. 4, then four times 2 mm. of the length of periphery of the butt joint is exposed through the highly permeable paper.
- This shape of perforation allows for the case when the perforations become slightly offset from the jointif circular they will shorten the length of periphery exposed, but if lozenge shaped as shown, a slight offsetting does not alter the length exposed.
- any shape, number, combination or angular relation of perforation may be used, but the use of a lozenge shape as shown conveniently permits controlled variation of extent of the length of periphery exposed through the highly permeable paper, without unduly weakening the joining band.
- the joining band is made double the width of those shown in FIGS. 4 to 6 and is perforated close to both edges.
- the mid lines of the gaps between the sets of four perforations illustrated are the positions at which the web is cut to join two cigarettes and an intermediate double length stub and the double length web is subsequently cut midway of its width to provide two composite cigarettes.
- FIG. 1 The only difference between FIG. 1 and FIG. 2 is that the encircling hand does not extend to the end of the stub, while in FIG. 3 the web 3 of less permeable material encircles the whole length of the stub 2 and the web of highly permeable paper 7 is secured near the edge of the web 3 that encircles the butt joint 5.
- Chain lines 16 and 116 and dotted lines 11, 12, 13, 14 and 15 have been superimposed on FIG. 4 to assist in indicating the extent of the gumless areas found suitable.
- the chain lines 16 and 116 indicate where the individual laminated encircling bands 3 and 7 are severed.
- the narrow strip between line 10 and dotted line 11 is a gumless area.
- the other gumless area is bounded by the lines 12, 13, 14 and 15.
- the area between lines 13 and 16, but extended across the width of the encircling band, illustrates the extent of the overlap of the ends of the encircling band when the composite cigarette has been completed.
- the periphery of the gum ming roller corresponds to a multiple of the area be tween the lines 16 and 116 and of double width, symmetrical about the line 10.
- the periphery is patterned by machining it to provide a shallow reservoir for gum except at the areas bounded by lines 10 and 11, and 12, 13, 14 and 15.
- additional gummed areas 17, 18 and 19 may be provided as illus trated in FIG. 5.
- substantially impermeable material instead of securing highly permeable and less permeable material together, the latter being perforated, substantially impermeable material alone is used.
- material is shaved off the surface of substantially impermeable material to thin it at one or more areas along the line that corresponds with the butt joint between the tobacco portion and stub of the composite cigarette, thus rendering it highly permeable at said areas.
- a perforating machine as hereinbefore described can be set so as to completely perforate a web at spaced positions or it may be set so as to shave material off the surface at spaced intervals, thus rendering the material more permeable at said positions according to the thickness of material shaved 01f.
- pre-gummed substantially impermeable material material may be shaved from the gummed surface or the surface that becomes the outer surface, while if a non pre-gummed material is used, it is desirable to avoid applying adhesive to the inner surface at positions too near the shaved portions. This of course is avoided in a similar manner to that previously described, i.e. by using a patterned gumming roller.
- the line instead of shaving the line that corresponds to the 'butt joint between the tobacco portion and stub of the composite cigarette at one or more areas, the line may be thinned continuously by shaving a surface to provide an area, all around the butt joint, that is thinned and is thus highly permeable.
- a cigarette comprising a Wrapped charge of tobacco and a filter stub, the stub having first and second ends open to permit the passage of air and smoke and having an outer surface between the said ends, an end of the said wrapped charge of tobacco abutting an end of the said stub to form a joint so that smoke may be drawn through the tobacco and then through the stub, a band secured to both the Wrapped charge of tobacco and the said outer surface of the stub and extending across the said joint so as to completely cover the joint and so as to cover a measurable portion of the wrapped charge of tobacco and the said outer surface of the stub to connect together the Wrapped charge of tobacco and the stub, said band being substantially impermeable to air except that the portion of the band covering the joint has at least one area which is permeable to air, thereby permitting a controlled and limited passage of air through the permeable area into the joint between the wrapped charge of tobacco and the stub, the said area being of a size which is observable with the naked eye so that slight shifting
- a cigarette comprising a Wrapped charge of tobacco and a paper wrapped filter plug, the said plug being in abutment with the downstream end of the tobacco charge to form a butt joint, a first band of paper secured over both the wrapped tobacco charge and the wrapped filter plug, the said band extending a measurable distance upstream and downstream from the butt joint, a second band of the same size as the first band and disposed therearound thus covering the same extent of Wrapped tobacco charge and filter plug, the first band being constituted of highly permeable material, the second band being constituted of substantially impermeable material and being provided with a plurality of relatively large perforations so located as to at least partially cover the butt joint, the perforations and underlying highly permeable material determining the amount of air and insuring the passage thereof into the butt joint between the plug and the wrapped cigarette charge.
