DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The present invention relates to a smoking article used for inhaling and tasting volatile components of a flavour.


BACKGROUND ART

Known is a cylindrical instrument housing a flavour in its axial bore. This instrument comprises a cylindrical body housing the flavour. The volatile components of the flavour are sucked through a mouth portion formed at one end of the cylindrical body. The flavour is solid, which is granular or in the form of chips or tablets shaped from a powdery material. The solid flavour is directly held within the axial bore of the cylindrical body.
In the conventional instrument described above, the kinds of the solid flavours having a volatility sufficient for the sucking are very much restricted. Also, since the flavour is solid, it is difficult to control the amount of the volatile aromatic components of the flavour. Further, since the flavour is exposed directly to the atmosphere within the axial bore of the instrument, the aromatic components are evaporated or denatured during preservation, making it difficult to preserve the instrument over a long period of time.
It may be possible to use a flavour solution supported by a suitable carrier in place of the solid flavour. In this case, it is possible to house various kinds of flavours in the axial bore of the cylindrical body. It is also possible to control the amount of the aromatic components evaporated from the flavour. However, a solution is more volatile in general than a solid, making it more difficult to preserve the instrument housing a flavour solution over a long period of time. In addition the solution tends to ooze out of the cylindrical body.


DISCLOSURE OF THE INVENTION

The present invention is intended to provide a smoking article which permits using various kinds of flavours, easily controlling the amount of the volatile fragrant components, and suppressing the loss of the flavour during preservation.
According to the present invention, there is provided a smoking article, comprising 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 said thin wall portion formed therein so as to hold the flavour solution released from the plastic container.


BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is an oblique view, partly broken away, showing a smoking article according to one embodiment, of the present invention;
FIGS. 2A to 2C collectively illustrate a plastic container included in the smoking article shown in FIG. 1;
FIG. 3 is an oblique view, partly broken away, showing a smoking article according to another embodiment of the present invention; and
FIG. 4 shows how the smoking article shown in FIG. 3 is used.


BEST MODE FOR EMBODYING THE INVENTION

The term "smoking article" used herein is irrelevant to tobacco and denotes an article used for inhaling and tasting a volatile aromatic component evaporated or an aerosol of aromatic components formed from flavour or the like.
In the smoking article of the present invention, a flavour solution is housed in a plastic container included in the smoking article. The flavour solution can be prepared by adding water to a flavour composition. It is possible to use various kinds of water-soluble flavour compositions including, for example, compositions of tobacco type, menthol type, vanilla type, liquor type, honey type, chocolate type, dry fruit type, cinnamon type, fruit type, and maple type. The concentration of the flavour solution is related to the intensity of the taste and aroma which is inhaled and t
