摘要

The invention is a tar retention device for insertion in the smoke path of a cigarette between the point of combustion and the smoker. The device is comprised of a chamber with an inlet duct formed on the side of the point of combustion and outlet side facing the smoker. The inlet duct is narrower than the outlet duct and each duct tapers towards their respective ends inside of the chamber. The difference in dimensions of the inlet and outlet ducts creates a hypobaric action within the chamber causing the deposition of tar within the chamber.
