发明名称 TIPPING PAPER AND CIGARETTE USING THE SAME
摘要 The vented filter cigarette is produced by combining a filter having a highly air-permeable circumferential surface and a tipping paper having a plurality of pores. The tipping paper has an embossment in the area of the pores formed therein. The embossment serves to create a slight gap between the tipping paper and the circumferential surface of the filter, by which the tightness therebetween is loosened. Thus, the filter ventilation is increased, and the variation in the degree of the ventilation can be reduced.
