Definitions
- Figure 1 illustrates a prior art plug-space-plug filter for a smoking article
- Figure 2 illustrates an embodiment of a plug-space-plug filter including a plug of randomly-oriented fibers
- the adsorbent is flavor-bearing or otherwise impregnated with a flavor so that the adsorbent is adapted not only to remove one or more gas phase smoke constituents from smoke, but also to release flavor into the mainstream smoke stream.
- flavor can be added to activated carbon by spraying flavorant upon a batch of activated carbon in a mixing (tumbling) drum or alternatively in a fluidized bed with nitrogen as the fluidizing agent, wherein flavorant may then be sprayed onto the carbon in the bed.
- the randomly-oriented fibers are cellulose acetate fibers.
- the randomly-oriented fibers are polyester fibers, polypropylene fibers, and the like.
- the randomly-oriented fibers can be woven and/or non-woven where the fibers are randomly joined together.
- smoke is drawn first through the plug 25 of axially oriented fibers 30, through the adsorbent 12, and downstream through the plug 16 of randomly-oriented fibers 14. Because of the random orientation of the downstream plug 16 of fibers, the adsorbent particles are not able to travel through the channels between the fibers or migrate along the fibers or both, resulting in the mechanical capture of the adsorbent particles entrained in mainstream smoke.
- the filter assembly 10 is adapted to be incorporated in a smoking article 50.
- smoking article includes cigarettes, cigars, pipes, and cigarillos.
- Non-traditional cigarettes such as cigarettes for electrical smoking systems, as described in commonly-assigned U.S. Patents 6,026,820; 5,988,176; 5,915,387; and 5,499,636, are also included in the definition of smoking articles or cigarettes generally.
