FIELD: tobacco industry.
SUBSTANCE: present invention relates to a smoking product with a cavity at the end brought to the mouth formed by a hollow tubular segment. The smoking product contains a tobacco rod and a filter connected to the tobacco rod. In this case, the filter contains a hollow part at the end brought to the mouth and a filtering part located upstream relatively to the hollow part at the end brought to the mouth. The filtering part contains one or several filter segments. In this case, the hollow part at the end brought to the mouth is formed by a hollow tubular segment, which is located at the end brought to the mouth of the filter, where the hollow tubular segment is surrounded by a wrapper to keep it in axial alignment with the filter segment and with the hollow part at the end brought to the mouth, and defines a cavity at the end brought to the mouth of the filter, providing a channel for unlimited flow that passes from the downstream end of the filtering part to the end brought to the mouth of the filter. The length of the hollow part at the end brought to the mouth is within 5 mm of the length of the filtering part, wherein the smoking product contains a ventilation zone containing at least one annular row of perforations provided in place at a distance of at least approximately 5 mm upstream from the downstream end of the filtering part, and the mentioned one or several filter segments of the filtering part contain the first filter segment. Moreover, the length of the first filter segment is at least 8 mm.
EFFECT: elimination of the deformation of cavities at ends of the filter brought to the mouth with an increase in their length.
