Abstract:
1. A method of forming a barrier in a filter of a smoking article, the method comprising the steps of: providing a delivery device having a container holding a supply of viscous fluid, which when placed in the filter forms a barrier that traps tar and nicotine within the filter, and a delivery feature having an outlet that is in fluid communication with the container; placing the delivery feature at a predetermined location within the filter that is sufficiently remote from a free end face of the filter to prevent a user from tasting the viscous fluid; and transferring the viscous fluid from the container to the filter through the outlet of the delivery feature by laterally injecting through a side wall of the filter, wherein the delivery feature comprises at least one tube having a significantly lesser diameter than a diameter of the smoking article.
