Definitions

This invention relates to a smoking article in which the smoking material can be tobacco or any other suitable material.
composition of the cigarette smoke aerosol is complex, containing many compounds in the particulate and vapour phases. It is possible to classify the compounds contained within the particulate phase into two fractions, these are the involatile and semivolatile fractions.
the semivolatile fraction can be defined as consisting of all of those compounds which evaporate from a chemically inert substrate heated to a temperature of 200°C.
a smoking article comprises a rod of smoking material and a filter portion, said filter portion including means for collecting particulate matter in the smoke from the rod of smoking material in a collection zone, and means for heating said collection zone to release the semivolatile compounds whilst allowing the involatiles to be retained in the filter.
the rod of smoking material includes a longitudinally extending passage to feed hot gases from the tip of the article when lit to the said collection zone.
the collection zone is provided by an impervious transversely extending member on which the particulate matter is deposited by the smoke from the smoking material.
the transversely extending member can be provided by a disc the centre portion of which provides said collection zone and which is surrounded by an exit opening or openings.
the disc is provided in a chamber into which smoke from the smoking material is delivered and into which the longitudinally extending passage feeds hot gases to the collection zone.
If desired means may be included for accelerating the hot gases from the passage into the collection zone.
the collection zone can be provided in a high retention filter element.
the high retention filter element can be spaced away from the end of the smoking material rod to form a chamber adjacent the collection zone and into which smoke from the smoking material is delivered and into which the longitudinally extending passage feeds hot gases to the collection zone.
a secondary filter element can be provided which is located at the mouth piece end of the article.
the passage in the rod of smoking material is formed by a low porosity/permeability tube.
the smoking article according to the invention comprises a rod 1 of smoking material, for example tobacco, carried in a paper outer wrapper 2.
the rod is provided with a longitudinally extending passage 3 formed by a tube of low porosity/permeability material 4 which may be made from paper or reconstituted tobacco sheet.
the tube may have a diameter typically in the range of 0.5 to 5 mm.
a filter 5 located within the paper wrapper 2 is a filter 5 at the mouth piece end and an impervious transversely extending member in the form of an impaction disc made of material which is temperature stable.
the materials from which the disc may be constructed include metals, for example aluminium, ceramics or plastics such as nylon, polyethylene, polypropylene or cellulose acetate.
the disc has a low thermal heat capacity and it may also have a low thermal conductivity, for example when constructed from a ceramic or from Nylon 66.
This disc 6 has a central impaction surface 7 which is surrounded by circumferential holes 8 typically of 1 mm diameter.
a chamber 10 is formed in which is located a second disc 11 which can also be made from a material selected from the examples given for the disc 6, and this may be the same as, or different from, that used in the construction of the disc 6 in a particular construction.
a second disc 11 which can also be made from a material selected from the examples given for the disc 6, and this may be the same as, or different from, that used in the construction of the disc 6 in a particular construction.
One or more (three are shown) small diameter holes 12 are provided in the disc 11 and these may typically be of 0.1 - 1 mm diameter and preferably 0.4 - 1 mm diameter. These holes act as acceleration nozzles in the manner to be described.
the impaction surface provided by the surface 7 is located typically 2 mm from the nozzles 12.
the passage 3 is located coaxially with the smoking material rod 1 but it could be displaced to one side if desired.
the means for collection particulate matter in the smoke from the rod of smoking material is provided by a high retention filter element 15.
the element 15 is spaced away from the end 9 of the smoking material rod and the filter 15 is located in a chamber 10 in place of the disc 11.
the disc 6 is also dispensed with.
smoke from the rod 1 impinges on the front surface 16 of the filter 15 and the filter retains a fraction of the total particulate matter over the first few (ten) mm of filter material. This is indicated by reference numeral 17.
This retained total particulate matter is again heated by hot air or smoke drawn down the passage 3 as in the previous embodiment.
the second filter element 5 can be spaced away from the filter element 15 as shown or it may abut it. Once again the action of the hot air or smoke heats the deposited particulate matter and releases the semivolatile fractions which are then drawn through the filter 5.
the second filter element 5 may have an inclusion of activated carbon to reduce the concentration of some of the vapour components in the smoke aerosol.
ventilation air may be introduced through the wrapper 5 into the filter 17 through openings 18 to confine the aerosol and the hot air/smoke stream to the central part of the filter.
ventilation air may be introduced through the wrapper 5 through openings 19 to aerodynamically focus the aerosol onto the disc 6 to improve the efficiency of the filter.
ventilation air may also be used to cool the evaporated semivolatiles to facilitate recondensation before delivery to the smoker, for example through openings 20.
