The following specification describes the invention:

A novel bidi with reduced harmful effect
Field of invention:
The present invention relates to tobacco related product, particularly bidi and more particularly filter bidi products.
Background information:
Bidis (pronounced bee-dees), also spelled beedis or biris, are small hand-rolled cigarettes manufactured mainly in India and other Southeast Asian countries. These are made by wrapping tobacco in a tendu (that is temburini or Diospyros melonoxylon) leaf. Bidis, though containing less tobacco and smaller than standard cigarettes, produce three times more carbon monoxide and nicotine, and five times more tar than a standard cigarette.
To reduce the tar and other fine particles in a cigarette, the cigarette manufacturers typically use a filter at one end of the cigarette, through which smoke is drawn. The filter retains the tar and other fine particles in the smoke, thereby making the inhaled smoke less harmful than the unfiltered smoke. The raw material for a typical cigarette filter is cellulose which is obtained from wood. The cellulose is acetylated, dissolved, and spun into continuous synthetic fibers arranged into a bundle called tow. Conventional bidis are produced without a filter or any filter like material for the purpose of removing tar and fine particles from smoke. Attempts have been made to reduce the tar content of bidies by replacing tobacco by other herbs. For example, the patent application WO2004068974 describes the preparation of herbal filler composition for bidi, cigarette and the like comprising leaves of Lawsonia inermis L. and Ocimum santurn L.
Non-filter bidis that produce harmful unfiltered smoke are consumed by hundreds of million people in the world. There is a need to provide a mechanism to reduce the tar content and fine particles generated during the consumption of bidis.


Description of the present invention:
Inventor has worked on different types of techniques which can be used to reduce the above mentioned drawbacks of the bidis and has discovered that by inserting a filter made of suitable filtering materials alone and/or in combination at the tip of the bidis, the content of tar and the fine particle content of the smoke of tobacco - based products can be reduced drastically and the smoke also become less injurious for the health.
The inventor has therefore used filter material to reducing tar and fine particles generated during bidi smoking. The technical evaluation of the product is under way.
