A method of manufacturing a smoking article including a tube filter includes preparing a smoking material portion, a first tube filter flavored by a first flavoring liquid, and a mouthpiece flavored by a second flavoring liquid; and combining and packaging the smoking material portion, the first tube filter, and the mouthpiece with a wrapper, wherein the preparing comprises applying the first flavoring liquid inside the first tube filter through a hollow of the first tube filter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a smoking article comprising a tube filter, the method comprising: preparing a smoking material portion, a first tube filter flavored by a first flavoring liquid, and a mouthpiece flavored by a second flavoring liquid; and combining and packaging the smoking material portion, the first tube filter, and the mouthpiece with a wrapper, wherein the preparing comprises: spraying, by a steam spray nozzle, steam of 80° C. to 150° C. onto an external surface of a tube-shaped rod for the first tube filter; and subsequently applying the first flavoring liquid inside the first tube filter through a hollow of the first tube filter by using a flavoring nozzle, and wherein the flavoring nozzle and the steam spray nozzle are apart from each other by 180 mm to 350 mm in a longitudinal direction of the first tube filter. 2. The method of claim 1 , wherein the applying further comprises applying the first flavor liquid to an inner surface of the first tube filter in an amount of 0.3 mg to 1.0 mg per millimeter. 3. The method of claim 2 , wherein the applying further comprises: applying the first flavoring liquid to the inner surface in an amount of 0.3 mg to 0.6 mg per millimeter, using the flavoring nozzle having a diameter of 0.8 mm to 1.1 mm, or applying the first flavoring liquid to the inner surface in an amount of 0.7 mg to 1.0 mg per millimeter, using the flavoring nozzle having a diameter of 1.2 mm to 1.4 mm. 4. The method of claim 3 , wherein the preparing further comprises: cutting the tube-shaped rod into the first tube filter after the first flavoring liquid is applied, wherein the first flavoring liquid contained in the first tube filter after the cutting is from 92% to 99.9% of a total amount of the first flavoring liquid applied to the first tube filter before the cutting. 5. The method of claim 1 , wherein an amount of the first flavoring liquid applied in the hollow of the first tube filter is 10% to 200% of an amount of the second flavoring liquid applied in the mouthpiece.
