  • Patent number: 6626182
    Abstract: A cigarette holder for extracting tar has first tar extractor with a stick and a first disc with apertures. A second tar extractor has a cylinder fitted to the stick and a second disc provided on one end of the cylinder and fitted in a flue of transparent resin. Smoke collision portions in the flue face the apertures. Smoke is compressed and accelerated when it passes through the apertures and expands again to collide with the smoke collision portions. It then collides with the second disc. Then the smoke is compressed and accelerated when it passes through the outer circumference of the second disc and the flue. Tar is extracted at each stage and the smoke is cooled by the second tar extractor before it reaches a mouth piece of the holder.

  • Patent number: 4344444
    Abstract: A cigarette holder having an attractive appearance and a compact structure suitable for use by ladies without any feel of reluctance, and capable of effectively removing nicotine and tar while permitting a visual check of the state of removal of nicotine and tar from the outside. A nicotine extractor made of a colored material, for removing the nicotine and tar by impact caused by collision of smoke, is fitted in a cigarette holder body made of a transparent material. When the colored nicotine extractor has become invisible from the outside of the cigarette holder body due to accumulation of nicotine and tars, the cigarette is no longer usable and can be discarded.
