Instead, tipping paper include that the known smoking article of multiple discharge orifice is likely to be of discharge orifice can be relatively easily by user
The shortcoming that finger is blocked.The concordance of the smog being transported to user can be had a negative impact by this.
Smoking article 10 also can have the advantage providing more effective strainability.This is because vent air and filter
Smog mixing outside 12.In contrast, the known smoking article during vent air is introduced in filter 12 is likely to be of and draws
The vent air entered increases the shortcoming of the flow rate of the mouth end towards filter 12, and therefore reduces the time of staying of smog.This
Strainability can be had negative effect.
Because filter 12 is preferably completely covered, so smoking article 10 also can have by interior and outer cover 13,14
The advantage less with the amount of smoke that the finger of user contacts.This is because entrance away from user finger generally remain position
Put.In contrast, in tipping paper includes the known smoking article of multiple discharge orifice, such as, do not aspirate smoking thing when user
During product, smog may escape discharge orifice and contact with the finger of user.
