Definitions

  • the present invention relates to a wrapper for a smoking material rod and also to a method of making a smoking material rod wrapper.
  • wrappers for smoking articles in which the wrapper is formed as a single sheet are well known.
  • EP-A-0 407 022 discloses a wrapper for smoking articles in which the wrapper comprises a single paper sheet formed from two or more discrete webs, the webs being combined while at least one of the webs is still in the wet stage of formation before drying.
  • EP-A-0 475 580 discloses a wrapper for smoking articles, the wrapper comprising a single paper sheet having two or more plies, each ply being formed from a paper stock and wherein the paper stocks are applied to each other while at least one of the stocks is unformed.
  • one of the plies may contain carbon.
  • Flavourant materials such as menthol have been applied to smoking articles to modify the smoke and taste characteristics thereof.
  • Flavourant materials have been added to smoking articles by various methods, for example, by spraying a flavourant-containing solution onto tobacco or by applying flavourant material to the cigarette paper.
  • a flavourant-containing solution onto tobacco or by applying flavourant material to the cigarette paper.
  • flavourant material due to the volatile or semi-volatile nature of many flavourant materials a significant amount of the flavourant material is lost through evaporation during the manufacture and storage of the smoking articles. Further, during smoking, more flavourant material is volatilised by the smoke in the initial puffs, resulting in uneven provision of the flavourant material to the smoker.
  • flavourant encapsulation techniques involve encapsulation of a flavourant material within a polysaccharide coating.
  • EP-A-0 490 559 discloses a filament comprising a core of flavourant material and polysaccharide binder with a coextensive alginate sheath coating. It is, however, difficult to insert such a filament into a cigarette using conventional high speed machinery. The control of flavour delivery to the smoker at specific stages during smoking is also not easily achieved using such filaments due to a necessity for precise positioning of the flavourant material in a cigarette.
  • a further encapsulation technique for smoking article involves microencapsulation of a flavourant material, and incorporation of the microcapsules into a tobacco blend. Disadvantages of such a technique include the difficulty in attaining an even distribution of microcapsules in the smoking article if desired, or alternatively, the difficulty in precisely positioning the microcapsules in a specific location in a smoking article.
  • WO 2005/082180 discloses smoking articles comprising a rod of smokable material, a wrapper about the rod of smokable material and a web material comprising an adsorbent material and a flavourant, the web material being positioned between the rod of smokable material and the wrapper and preferably being adhered to the wrapper using an adhesive.
  • the adsorbent material may be carbon.
  • a filler material such as calcium carbonate and a burn additive such as citrate are preferably used. The presence of such filler and burn additive are often desirable to control sparking problems associated with the use of the carbon-containing web.
  • a smoking material rod wrapper which comprises a single sheet comprising two or more plies, wherein a first ply comprises fibrous material, and a said second ply comprises adsorbent material, fibrous material and flavourant.
  • Applicant has found that a single sheet comprising at least two plies, wherein one of the plies contains adsorbent material and flavourant, can be formed in which the flavourant is stabilised by the adsorbent material such that the flavourant is not released prior to smoking of a smoking material rod enwrapped in such sheet, and in which the presence of filler and burn additive may not be required in order to control sparking problems.
  • the single sheet can be produced having a thickness similar to that of conventional cigarette papers, it can be used in conventional cigarette manufacturing machinery for producing smoking articles.
  • a still further advantage of forming a wrapper for a smoking material rod is that it can be formed remote from the smoking material rod making machine. For example, it can be formed and then transported to the smoking material rod manufacturer, as for a conventional cigarette paper. This is advantageous as it reduces the complexity of the manufacturing machinery required by the smoking material rod manufacturer since the smoking material rod manufacturer does not require machinery to manufacture the sheet itself. As such, the invention can allow the smoking rod manufacturer to produce improved smoking rods without requiring any modification or replacement of their existing machinery.
  • a still further advantage of single sheet comprising at least two plies, wherein one of the plies contains carbon and flavourant wrapper, is that, when used to enwrap a smoking material rod it potentially enables certain smoke constituents generated by the smoking material rod during use to be reduced.
  • wrapper enables issues with regard to ashing characteristics and sparking to be avoided or reduced.
  • the sheet may comprise more than two plies, the sheet may be a double ply sheet, i.e. has only two plies.
  • the fibrous material present in the first and/or second ply is preferably a fibrous cellulosic material. More preferably, the fibrous cellulosic material is in the form of a paper material.
  • the fibrous material may, for example, be present in the second ply in an amount of up to 40 g/m 2 .
  • the fibrous material may, for example, be present in the second ply in an amount of up to 20 g/m. 2
  • the total amount of fibrous material in the sheet may be at least 17 g/m 2
  • the total amount of fibrous material in the wrapper may be up to 60 g/m 2 .
  • the flavourant may be selected from the following compound types: menthol (natural and/or synthetic), alcohols, esters, ketones, lactones, essential oils, aldehydes and heterocyclic compounds. A number of other flavourants may be suitable.
  • menthol natural and/or synthetic
  • alcohols esters, ketones, lactones, essential oils, aldehydes and heterocyclic compounds.

  • the one or more burn additive may, for example, be present in an amount of at least 0.5% by weight based on the weight of the sheet.
  • the one or more burn additive may, for example, be present in an amount of up to 1% by weight based on the weight of the sheet.
  • the one or more burn additive may be present in an amount of from 0.5 to 1 % by weight based on the weight of the sheet.
  • the one or more adsorbent material present in the second ply may be selected from one or more of the following: zeolite, sepiolite, clay, activated alumina, mineral, resin, and carbon.
  • the adsorbent material may be carbon.
  • the adsorbent particularly may be activated carbon. Any form of activated carbon may be used. Activity of carbon is measured in per cent carbon tetrachloride (CTC), a measurement well known in the art.
  • the activated carbon may have an activity level (CTC) of from 60 to 130, and preferably from 80-120, and may suitably be approximately 100.

  • the one or more filler material may comprise calcium carbonate.
  • the one or more filler material may, for example, be present in the second ply in an amount of up to 25 g/m 2 .

  • the wrapper may have a thickness of at least 45 ⁇ m.
  • the wrapper may have a thickness of up to 250 ⁇ m.
  • the second ply extends over at least a part of one surface of the first ply. In embodiments of the present invention, the second ply extends over the whole of one surface of the first ply. It is to be understood that, in the situation where more than two plies are present in the single sheet, the second ply may be separated from the first ply by one or more additional plies.

  • the one or more flavourant may be added to the adsorbent material prior to forming the second ply.
  • the flavourant may be added to the adsorbent material by spraying.

  • the flavourant may be added to the second ply using a flavour applicator means, for instance as a stream or streams of flavourant.
  • a flavour applicator means for instance as a stream or streams of flavourant.
  • the plurality of streams of flavourant is applied to the second ply in a line or in an array.
  • the array may comprise two lines of streams of flavourant, one of the lines being offset from the streams of flavourant in an adjacent line.
  • the flavourant is applied to the surface of the second ply as 1 to 30 streams of flavourant, and preferably as 4 to 18 streams of flavourant.
  • flavourant is solid at room temperature, it is heated to maintain the flavourant in the molten liquid state during application to the adsorbent or to the second ply, and may be heated to a temperature of 40 to 45°C.
  • the wrapper may be formed by any suitable method provided that the resultant wrapper comprises a single sheet.
  • single sheet refers to a sheet in which the plies thereof are integral in the sense that the plies are not merely placed adjacent to one another or adhered to one another using such as adhesive (i.e. as in the case of WO 2005/082180 ).
  • the wrapper is formed by combining the two or more plies to form the single sheet while at least one of the plies is in the wet stage of formation prior to drying.
  • the plies may be combined while one of the plies is in the wet stage of formation prior to drying, or while both of the plies are in the wet stage of formation prior to drying.
  • the present invention also provides a method of preparing a wrapper according to the invention, which method comprises combining said plies while at least one of said plies is still in the wet stage of formation prior to drying.
  • An apparatus suitable for use in preparing the wrapper may, for example, be a multi-wire paper making machine such as a double wire paper making machine. Such machines are known in the art of paper making.
  • the formed sheet is typically dried.
  • the present invention further provides a smoking article as defined in the claims.
  • the second ply of the wrapper is located on the smoking material rod side of said wrapper since this will be more aesthetically pleasing to the majority of smokers. That is, the second ply, which contains the adsorbent material, will be located between the first ply and the smoking material rod such that the second ply will not be visible to the smoker. This allows the adsorbent material to be relatively proximate to the flow of smoke through the smoking article, thereby allowing greater interaction with constituents of the smoke than would be the case if the second ply were an outer ply. Thus, the removal of vapour phase constituents is enhanced. This also allows the outward appearance of the plug wrap not to be affected, or to be affected less, by the content of the second ply. This is particularly useful in the case where the adsorbent material in the second ply is carbon.
