Abstract

A smoking article comprising a first tobacco rod 12 and a further tobacco rod 14 detachably attached to the first tobacco rod hence enabling the smoke generated from the first tobacco rod on burning to pass through the further rod. Preferably, the tobacco rods are detachably held together by a sleeve 16. Suitably, the sleeve can be permanently part of the first tobacco rod and either slidably fitted to the second, or be separable therefrom by a tear strip. <IMAGE>

Description

SMOKING ARTICLE The -present invention relates to smoking articles.

Smoking articles consisting of a tobacco rod and filter attached longitudinally are well known. It is also known to provide a varying blend of tobacco along the length of the tobacco rod.

The present invention provides a smoking article comprising a first tobacco rod and a further tobacco rod detachably attached to the first tobacco rod hence enabling the smoke generated from the first tobacco rod on burning to pass through the further rod. Preferably, the tobacco rods are detachably held together by a sleeve. Suitably, the sleeve can be attached to the first tobacco rod.

Embodiments of the present invention will be described by way of example, with reference to the accompanying figures, in which: Fig. 1 is a longitudinal cross-section through a first embodiment of smoking article, Fig. 2 is a cross-section through the smoking article of Fig. 1 after removal of the first tobacco rod, and Fig. 3 is a side view, partially in longitudinal cross-section, of a second embodiment.

Fig. 1 shows a cigarette having a filter 10, a first tobacco rod 12, and a second tobacco rod 14. The filter 10 is optional. The first tobacco rod 12 is enclosed within a first cigarette paper 16 which extends beyond an end of the first tobacco rod 12 to form a sleeve which receives an end of the second tobacco rod 14. The second tobacco rod 14 is enclosed within a second cigarette paper 18. Alternatively a separate sleeve may be attached to the end of one or other rod, to fit tightly but removably over the other.

The first tobacco rod may be removed from the remainder of the double cigarette by pulling in the direction indicated by arrow 20, thus leaving behind the filter 10 and second tobacco rod 14 as shown in Fig. 2.

In a second embodiment, the first tobacco rod 12' has a paper 16' which is glued over the paper 18 of the second rod 14 in the region 21. To allow separation of the two rods, the paper 16' includes a tear strip 22 by which the paper 16 may be severed if desired.

In the embodiments shown, the extended portion of the first cigarette paper 16 is a relatively stiff paper, to prevent adverse distortion when the article is handled. The two cigarette papers 16 and 18 may be the same or different papers. The tobaccos in the two tobacco rods may be of identical blends, or of different blends. Either may contain added flavourings or both blends may be flavoured with the same or different flavours. The packing densities of the two blends may be the same or the two may have different packing densities.

Since the smoke of the first tobacco rod passes through the tobacco of the second tobacco rod during smoking, tar from the first tobacco rod will be deposited within the second tobacco rod. Thus, it is possible to use a lower tar yield tobacco in the second tobacco rod.

Thus by suitable choice of the tobaccos and/or tobacco packing densities the puff-by-puff delivery profile may be rendered more uniform than is normal in conventional cigarettes. This can be achieved for example by the use of a lower packing density in the first tobacco rod 12 and a higher packing density in the second tobacco rod 14 and alternatively or additionally, tobaccos of different inherent tar yields with that in tobacco rod 12 being higher than that in tobacco rod 14.

One or both tobacco rods may be shorter than the conventional length cigarette, for example half the normal length. Optionally, one or both cigarettes may be filtered and may be provided with ventilation zones in the cigarette paper or the tipping.

In yet other embodiments, the detached separable tobacco rod 12 may have additional material (supplied separately) inserted into the extended portion of the cigarette paper 16. Tobacco rod 12 may then be smoked independently of tobacco rod 14 or the additional material may be entrapped longitudinally between the two tobacco rods when tobacco rod 12 is repositioned on tobacco rod 14. If tobacco rod 12 is repositioned on tobacco rod 14 after insertion of the additional material, the ventilation zone, if present, in the extended portion of the cigarette paper 16 may be left exposed over an empty chamber, or may be in a position over the plug of additional material, or may be occluded by the cigarette paper 18.When the re-assembled article is to be smoked completely, the inserted material must be a smoking material, in a configuration which enables smoke to be drawn through them and which will enable the "coal" to pass from one rod to another. When the article is disassembled into two cigarettes for smoking individually, a wider range of additional materials may be inserted into the extended sleeve 16 of the rod 12.

Subject to the above, the additional material may for example be a tobacco or reconstituted tobacco material and may bear flavouring, or may be an additional active element such as cellulose acetate tow or plug of a range of filter efficiencies optionally bearing graphite, activated carbon, granules which may be metallized, humidifiers or the like. It may be in the form of a plug wrapped in either a porous or a non-porous wrapper. If desired, the insertion of the additional material within the wrap of the separable part of the filter may be accomplished by applying pressure via a piston to capsules or cartridges of the material held within an applicator tube of size to feed within the exposed cigarette paper 16 of tobacco rod 12.

When smoking the article of the present invention, a smoker is given the option of smoking the two cigarettes independently of each other at different times, thus giving two shorter intervals of smoking, or of smoking a combined unit formed of the two tobacco rods.

Claims (10)

CLAIMS:
1. A smoking article comprising a first tobacco rod and a second tobacco rod having a mouth end, the first tobacco rod being detachably attached to said second tobacco rod, whereby smoke generated upon burning the first tobacco rod passes through the second tobacco rod to said mouth end.
2. A smoking article according to claim 1 in which the tobacco rods are detachably held together by a sleeve.
3. A smoking article according to claim 2 wherein the sleeve includes a tear strip.
4. A smoking article according to claim 2 or claim 3 in which said sleeve is part of the first tobacco rod.
5. A smoking article according to any preceding claim in which the tobacco contained in said first tobacco rod is of a higher tar yield than the tobacco in said second tobacco rod.
6. A smoking article according to any preceding claim in which the packing density of the tobacco in said first tobacco rod is lower than the packing density of the tobacco in said second tobacco rod.
7. A smoking article according to any preceding claim further comprising between said first and second tobacco rods an element for modifying the quantity or quality of the smoke which is generated by burning the first tobacco rod.
8. A smoking'article according to any one of the preceding claims wherein the rods have been separated to form two separate smokable portions each having a mouth end, at least the first tobacco rod having additional material at its mouth end.
9. A smoking article according to claim 8 wherein the additional material is inserted in a sleeve extending the first tobacco rod.
10. Smoking articles substantially as described herein with reference to the accompanying drawings.
