Abstract
A device comprising a filter and a rod which is capable of insertion into a cigarette cord that has a preformed conduit extending concentrically along the longitudinal axis of the cord. The rod having a plurality of perforations along its entire length, allowing for a fresh air supply to be sucked into the rod and then intermingled through the tobacco. The filter being available in various numbers of filtering ring elements which allow for a selection of filtering strength. The device is made of materials that would allow it to be reusable. As the cigarette cord burns down, the increased supply of fresh air will result in a reduction in the percentages of particulate matter (tars, nicotine,etc). By varying the number of filters, the taste will selectively be controlled by the user.
Claims20
A cigarette aeration and filtration device comprising:
- an elongated cigarette cord having a mouth end and a lit end, a preformed air permeable conduit longitudinally and coextensively deposed within the cord, the cord having a concentric core of shredded tobacco encircling the conduit, a porous paper wrapping the entire lateral surface of the cord;
- an elongated cylindrical rod having an outside diameter being substantially equal to the diameter of the preformed conduit of the cigarette cord, the rod being inserted into the preformed conduit, the preformed conduit separating the rod from the shredded tobacco, the rod having a smoking end and a suction end, the cylindrical surface of the rod defining a plurality of ventilation holes evenly dispersed along the length of the rod, the rod being hollow with an internal surface defining an air passage channel extending the entire length of the rod and being coaxial with the cigarette cord, whereby air, being cooler than the smoke stream causes both condensation and reduced toxic content, is sucked into the air passage channel through both the smoking end of the rod and the ventilation holes, is dissipatable through the shredded tobacco;
- and
- a filter element integral with the suction end of the rod, the filter element having a fill of fibrous material, a porous paper wrapper concentrically covering the filter element, one end of the filter element being an air intake and the other end a flange, the flange having an outside diameter at least equal to the diameter of the cigarette cord, the flange serving to seal the filter element and the cigarette cord, the flange having a face surface defining a plurality of intake holes for directing the smoke stream through the filter element, whereby the condensation in the smoke stream will cause the particulate matter to drop out and deposit in the tobacco and fill matter thereby creating a cleaner and healthier smoke stream that enters the user's lungs.

A cigarette aeration and filtration device comprising:
- an elongated cigarette cord having a mouth end and a lit end, a preformed air permeable conduit longitudinally and coextensively defined by a surface made from reconstituted tobacco products, the cord having a concentric core of shredded tobacco encircling the conduit, a porous paper made from conventional combustion type paper wrapping the entire lateral surface of the cord;
- a reusable elongated cylindrical hollow rod having an outside diameter being substantially equal to the diameter of the preformed conduit of the cigarette cord, the rod being inserted into the preformed conduit, the preformed conduit separating the rod from the shredded tobacco, the rod being made from a lightweight material that will neither burn nor be hazardous to the health of the smoker includes a smoking end and a suction end, the cylindrical surface of the rod having a plurality of ridges evenly dispersed along the length of the rod, each ridge having a vertical wall for stabilizing the rod within the cigarette cord and a slanted surface having defined therein a ventilation hole, the rod having an internal surface defining an air passage channel extending the entire length of the rod and being coaxial with the cigarette cord, thereby air being sucked into the air passage channel through both the smoking end of the rod and the ventilation holes is then dissipated through the shredded tobacco whereby the air being cooler than the smoke stream causes both condensation and reduced toxic content thereof;
- and
- a filter element integral with the suction end of the rod, the filter element having a fill of fibrous material, a porous paper wrapper concentrically covering the filter element, one end of the filter element being an air intake and the other end a flange, the flange having an outside diameter at least equal to the diameter of the cigarette cord, the flange having a face surface defining a plurality of intake holes for directing the smoke stream through the filter element whereby the condensation in the smoke stream will cause the particulate matter to drop out and deposit in the tobacco and fill matter thereby creating a cleaner and healthier smoke stream entering the user's lungs.

A cigarette and aeration device for use with a cigarette having a preformed conduit, the device comprising:
- an elongated cigarette cylindrical rod having an outside diameter being substantially equal to the diameter of the preformed conduit of the cigarette, the rod being inserted into the preformed conduit, the rod having a smoking end and a suction end, the cylindrical surface of the rod defining a plurality of ventilation holes evenly dispersed along the length of the rod, the rod being hollow with an internal surface defining an air passage channel extending the entire length of the rod and being coaxial with the cigarette, thereby, air sucked into the air passage channel through both the smoking end of the rod and the ventilation holes, is dissipated through the cigarette whereby the air, being cooler than the smoke stream causes both condensation and reduced toxic content thereof;
- and
- a filter element integral with the suction end of the rod, the filter element having a fill of fibrous material, a porous paper wrapper concentrically covering the filter element, one end of the filter element being an air intake and the other end a flange, the flange having an outside diameter at least equal to the diameter of the cigarette, the flange serving to seal the filter element and the cigarette, the flange having a face surface defining a plurality of intake holes for directing the smoke stream through the filter element whereby the condensation in the smoke stream will cause the particulate matter to drop out and deposit in the cigarette and fill matter thereby creating a cleaner and healthier smoke stream that enters the user's lungs.
