  • Patent number: 5331981
    Abstract: A smoking article includes a flexible casing which is liquid-tight and tubular, a mouth portion formed at one end of the casing, a cylindrical plastic container which can be elastically deformed and is arranged within the casing, a flavour solution housed in the plastic container and having a viscosity of 520 cP or less, a thin wall portion formed at one end wall of the plastic container, the thin wall portion being broken when the plastic container is elastically deformed upon receipt of force applied from outside the casing so as to permit release of the flavour solution, and a water absorbing layer formed adjacent to the end wall having the thin wall portion formed therein so as to hold the flavour solution released from the plastic container. Various kinds of flavour solutions can be used in the smoking article. The amount of the volatile aromatic components can be controlled easily. Further, it is possible to suppress the loss of the aromatic component during preservation of the smoking article.
