A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. A longitudinally extending inner core of tobacco cut filler is positioned within a smokable rod. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with an optional burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. A preferred aerosol forming material is glycerin. An outer paper wrapper circumscribes the length of the smokable rod, and another paper wrapping material also can circumscribe the inner core material. In use, one end of the smokable rod is lit. When the opposite end of the smokable rod is drawn upon, an aerosol composed of tobacco smoke, thermal decomposition products of tobacco, and volatilized aerosol forming material, is provided. Alternatively, a smokable rod can be provided by positioning the tobacco cut filler in the outer annular region, and by constructing the inner core portion using the tobacco material treated with aerosol forming material and an optional burn suppressing agent. Alternatively, a smokable rod possesses a single blend of smokable materials; at least a portion the smokable material being a tobacco material carrying a relatively high amount of aerosol forming material; and optionally at least a portion of the smokable material being in intimate contact with a burn suppressing agent. A filtered cigarette can be produced by attaching a filter element to one end of any of those smokable rods.

A filtered cigarette possesses at least one breakable capsule in its filter element. The filter element can possess a central cavity extending from the cigarette tobacco rod towards the middle of the filter element. The central cavity may be defined by an inner filter portion. The inner filter portion can be surrounded by an outer filter portion comprised of filter tow material that is generally permeable to the smoke generated by the cigarette. At least one breakable capsule is disposed in the central cavity of the filter element. The breakable capsules are spherical in shape, and are composed of a gelatin outer shell that encloses a payload of triglycerides and flavoring agents. The breakable capsules are adapted to rupture in response to pressure applied by the smoker to the outside region of the filter element.

The invention provides a cigarette with a filter element comprising at least one longitudinally extending section of filter material. The section of filter material comprises a smoke-altering material therein that is useful for removing a quantity of vapor phase chemicals from the mainstream smoke. The section of filter material further comprises one or more tubes inserted into and extending through section of filter material. The one or more tubes each define a channel adapted for passage of mainstream smoke through the section of filter material while substantially avoiding contact of the portion of mainstream smoke therein with the smoke-altering material. The provision of a portion of mainstream smoke substantially unaltered by the smoke-altering material can be useful to retain certain desirable taste and other sensory properties of the mainstream smoke.

Smoking articles, such as filter cigarettes, are packaged in a metal box which is curved to a shape that conforms to the curvature of the human body so that the box can be comfortably carried in a shirt or pant pocket. The metal box comprises a lid and a four sided tray. The lid and the tray have rolled lips which interengage to mechanically and slidably retain the lid to the tray. The lid covers the open front of the tray and is slidable along an arcuate path corresponding to the radius of curvature of the lid to selectively open or close the front of the tray. The lid of the box includes an abutment that prevents the lid of the box from being completely removed unless additional force is applied to push the abutment past the rear wall of the tray.

When detached from the outer body 10 along the separating line 14, the lid 12 is rotated around a self hinge 16 to open or close.

A non-combustion smoking tool, which uses a real filter cigarette as it is, and which vaporizes nicotine from the tobacco leaves without lighting the product to enable inhalation of the vaporized nicotine, has a problem that a smoker cannot take in 100% of the vaporized nicotine. Thus, a mouthpiece is designed to have an air flow control structure or an air flow control element, or to be combined with a cigarette guide tube, so as to enable the mouthpiece to vary the rate at which the nicotine vaporized from the tobacco leaves is taken in.

The invention provides sodium alginate microparticles for a cigarette filter and a filtered cigarette. The sodium alginate microparticles are prepared by the following steps: preparing a sodium alginate solution from sodium alginate with a viscosity smaller than 200mpa.s, then adding essence and spice, preparing sodium alginate particles by a dripping method, and finally drying to obtain the sodium alginate microparticles. By adopting the sodium alginate microparticles, the essence and spice can be added to a filter tip, the generation of hazardous materials due to pyrolysis of the essence and spice is avoided, and the fragrance of the cigarette during smoking is simultaneously increased.

An elongated strip of tipping paper is advanced in a tipping machine for the making of filter cigarettes. The strip advances past a perforating unit and thereupon past a cutting unit which subdivides the perforated strip into a series of uniting bands ready to be convoluted around abutting ends of plain cigarettes and filter rod sections. One side of the strip is coated with a film of an adhesive which can be inactivated by exposing it to coherent radiation. The perforating and cutting steps are carried out by one or two beams of coherent radiation which can further serve to inactivate the adhesive around each perforation and along the edges which extend across the strip to thus reduce the likelihood of penetration of active adhesive into the perforations and / or a contamination of the products by active adhesive being expelled beyond the marginal portions of the uniting bands. A single source can suffice to furnish coherent radiation for the carrying out of the perforating, cutting and inactivating operations.

A drum-shaped conveyor rotates about a fixed axis and its core carries a set of angularly distributed sections indexible about axes extending radially of the fixed axis when the core is set in rotary motion. Each section has several parallel flutes for sets of discrete filter cigarettes which are turned end-for-end, as well as moved circumferentially and axially of the core, in response to each revolution of the core. Rotation of successive sections about the respective radial axes takes place at timely spaced intervals and in opposite directions. The conveyor can receive filter cigarettes from a maker and inverts the sets of cigarettes prior to admission of such articles into a packing machine.
