Abstract
For decreasing a side stream smoke generated from a lighted tobacco product, a hollow main body made of non-combustive material and having a through hole is provided to accommodate the product therein. The main body permits continuous combustion of the product but limits the quantity of oxygen supplied to a burning point, thereby preventing generation of the side stream smoke while the lighted tobacco product is not inhaled.
