Claims

[Claims for Utility Model Registration] 1. A cylindrical porous filter rod portion, a smoke-impermeable wrap portion that extends from one end of the rod portion to surround the rod portion in the length direction and does not block the opposite shaft end; a tip portion extending longitudinally surrounding the wrap portion, the wrap portion having at least one longitudinally extending smoke-impermeable groove portion embedded in the filter rod; The groove is shorter in length than the length of the filter rod and has an opening to the filter rod at one end;
Further, the tip portion is air permeable and allows a flow of ventilation air to flow into the groove, and when the filter is used with normal smoking force, only the flow of ventilation air is allowed to pass through. Filter rod. 2. The filter according to item 1, which is combined with a cigarette having a groove opening adjacent to the mouthpiece of the filter. 3. A filter according to claim 2 in combination with a cigarette in which the groove opening has means for directing incoming air across the filter rod. 4. A filter according to claim 2, in combination with a cigarette, in which the opening of the groove has means for directing incoming air along the length of the filter rod towards the mouth end of the filter. 5. The filter according to item 1, wherein the tip portion is air permeable. 6. The filter according to item 1, which is combined with a cigarette in which the opening of the groove is adjacent to the cigarette. 7. The filter according to item 1, wherein the filter has a circumferentially extending groove communicating with the longitudinally extending groove, and the circumferentially extending groove is embedded in the filter rod and the wrap portion.
