发明名称 Smoking article
摘要 A smoking article (10) comprises a rod (12) of smokeable material and a filter (14) attached to one end of the rod. The filter comprises an elongate body of filter material (16) wrapped with a transparent plug wrap (18). A first tipping wrapper (20a) overlies the join between the rod and the filter to attach the filter to the rod. At least one additional tipping wrapper (20b) is provided around the filter, spaced from and separate to the first tipping wrapper such that a portion of the transparent plug wrap is exposed between the first and at least one additional tipping wrapper to define a window portion (22) through which the filter material is visible. A method of producing such a smoking article is also disclosed.
