NEW ZEALAND Patents Act 1953 COMPLETE SPECIFICATION TOBACCO MIXTURE FOR ROLL YOUR OWN SMOKING ARTICLES We. British American Tobacco (Germany) GmbH a German company of Alsterufer 4. 20354 Hamburg, Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement | Office of iv.2. ' 6 DEC 2006 'R E C E I V E D (Followed by 1A) Tobacco mixture for roll your own smoking articles The invention relates to a tobacco mixture for roll your own smoking articles, in particular for roll your own cigarettes. The tobacco mixture proposed by the invention is preferably used for making up filter-tipped cigarettes. By making up is meant rolling cigarettes by hand as well as preparing cigarettes with rolling machines, in particular hand rolling machines.

The consumer who rolls his own cigarettes prefers to receive a large volume of tobacco for a specific tobacco weight, so that he can roll a lot of cigarettes from a specific unit of tobacco in terms of weight (e.g. bag, tin). The volume which a specific quantity of tobacco is able to assume in the non-packed state in terms of weight, in other words as a loosely piled quantity, can be defined as "yield value". This yield value is an important parameter for such tobacco mixtures.

An objective of the present invention is to optimise the yield value of a tobacco mixture.

This objective is achieved by the invention on the basis of a tobacco mixture incorporating the characterising features described in claim 1. The dependent claims define advantageous embodiments of the invention.

For the purpose of the invention, a tobacco mixture for roll your own smoking articles, in particular for roll your own cigarettes, comprises a tobacco material in respect of which: - the moisture content of the tobacco mixture is in the range of 16-18%, - the cut width of the tobacco material of the tobacco mixture is in the range of 0.5-0.7 mm, and

Claims (6)

- the average length of the tobacco parts or tobacco fibres is shorter than that of normal finely cut tobacco, in particular up to a proportion of more than 30% of the tobacco mixture has a length of less than 4 mm. In combination and in terms of their mutual correlation, the above features result in a tobacco mixture with a surprisingly high yield value.. This means that a tobacco material with a surprisingly higher volume of the loose tobacco material can be produced from the same weight of tobacco material than is the case with conventional tobacco mixtures. Said parameters can therefore be selected so that the loose volumes of the tobacco can be significantly increased by reference to the tobacco weight; in particular, the tobacco mixture is more curled and therefore more resilient than conventional finely cut tobacco. The moisture content of the tobacco mixture is preferably 17%; the cut width is preferably 0.6 mm. In one variant of the invention, the tobacco mixture contains the leaf tobacco parts as the base material, which are of a length of less than 4 mm. In other words, the desired tobacco part length or tobacco fibre length can already be achieved if the base material already comprises pieces or parts that are shorter to this extent. In one embodiment of the invention, the tobacco mixture may be or may contain an American blend comprising Virginia, Burley and Oriental tobaccos in particular. In another preferred embodiment, a tobacco mixture is used which does not contain any expanded tobacco and another option is for the tobacco mixture to contain a tobacco material which has been treated with casing and/or flavouring.

1. Tobacco mixture for roll your own smoking articles, in particular for roll your own cigarettes, comprising a tobacco material characterised by the following features: the moisture content of the tobacco mixture is in the range of from 16 to 18 %; the cut width of the tobacco material is in the range of from 0.5 to 0.7 mm; and the average length of the tobacco parts or tobacco fibres is shorter than that of normal finely cut tobacco, in particular up to a proportion that is greater than 30% of the tobacco mixture has a length of less than 4 mm.

2. Tobacco mixture as claimed in claim 1, characterised in that the moisture content is 17%.

3. Tobacco mixture as claimed in claim 1 or 2, characterised in that the cut width is 0.6 mm.

4. Tobacco mixture as claimed in one of claims 1 to 3, characterised in that leaf tobacco parts with a length of less than 4 mm are used as the base material. 5. Tobacco mixture as claimed in one of claims 1 to 4, characterised in that it is or contains an American blend, in particular of Virginia, Burley and Oriental tobaccos. 6. Tobacco mixture as claimed in one of claims 1 to 5, characterised in that it does not contain any expanded tobacco. 7. Tobacco mixture as claimed in one of claims 1 to 6, characterised in that it contains a tobacco material that is treated with casing and/or flavouring. 8. A tobacco mixture according to claim 1 substantially as herein described or exemplified.
