KIT FOR MAKING A SMOKING ARTICLE

TROUSSE SERVANT A FABRIQUER UN ARTICLE DE FUMEUR

English Abstract

A kit for making a smoking article comprises a hull 10
which itself comprises a hollow cylinder 14 of cigarette paper
having a filter at one end joined to it by tipping 16. The kit
also includes a rectangular sheet 12 of reconstituted tobacco,
the long side of which is the same length as the cylinder. The
smoker rolls the sheet into a cylindrical shape and inserts it
into the hull to make a cigarette.

RIT FOR MARING A SMOKING ARTICLE
The present invention relates to a kit for making a smoking
article for assembly by a smoker. It also relates to a novel
smoking article.
It is known to provide, separately, unsmokeable components of
cigarettes to smokers for assembly into smokeable cigarettes.
Conventionally, a tobacco rod wrapped in a very high porosity
paper wrapper and, separately, an empty hull consisting of a
cylinder of conventional cigarette wrapper closed at one end by a
conventional filter plug attached to the wrapper by conventional
tipping are provided.
The porosity of the very high porosity wrapper is such that the
tobacco rod cannot be smoked. It is chosen, bearing in mind the
packing density and other characteristics of the tobacco in the
rod, to ensure that this is the case. Typical porosity values
for the very high porosity wrappers are around 20000 Coresta
units.
The smoker inserts the tobacco rod into a hull to make a
smokeable cigarette.
Another cigarette component system, described in European Patent
Application No. 93 305 363.9, consists of a tobacco column
wrapped in a conventional cigarette wrapper. At one end, a
hollow cylindrical extension is provided by a continuation of the
wrapper beyond the tobacco column. The extension is treated to
make it unsmokeable. The rod cannot be smoked, since drawing on
the extension will cause it to collapse, and the unsmokeable
nature of the extension makes it impossible to light that end and
smoke the rod. The smoker renders the rod smokeable by inserting
a filter plug into the extension.
According to the invention there is provided a kit for making a
smoking article comprising: a hull comprising a cylinder of
wrapping material preferably closed at one end by a filter; and

2138735
separately, a sheet of smoking material such as reconstituted
tobacco sheet.
Preferably the sheet of smoking material is generally
rectangular, and has a width the same as the hollow length of the
hull.
In order to make a smoking article, a smoker rolls the sheet into
a cylinder of slightly smaller diameter than that of the hull,
and inserts the rolled sheet into the open end of the hull.
The invention also provides a smoking article comprising a sheet
of smoking material, such as reconstituted tobacco, rolled into a
cylinder inside a cylindrical wrapper preferably provided with a
filter at one end.
The sheet of smoking material is preferably a conventional sheet
of reconstituted tobacco. It may be of flue cured, Burley,
oriental or blended tobacco. It is envisaged that a kit may
include several relatively thin sheets of reconstituted tobacco,
of different tobaccos or blends. The smoker selects two or more
such sheets, and rolls them together for insertion into a single
hull. In this way, the smoker can blend his own tobacco.
The smoker can add flavouring material to the sheet before
rolling it up and inserting it into the hull. The flavouring
material can be solid, such as a powder, or liquid.
The invention will be further described by way of example with
reference to the drawing which shows a preferred kit according to
the invention, in the process of being made into a smoking
article.
The kit shown in the drawing consists of a hull 10 and a sheet 12
of reconstituted tobacco. In the drawing, the sheet 12 is shown
rolled into a cylinder.
The hull 10 comprises a cylinder 14 of cigarette wrapper joined
at one end to a filter. The cylinder 14 consists of a sheet of
conventional cigarette wrapper formed into a cylinder and glued
along its free edges. The filter is axially aligned with the

~138735
,_
cylinder 14 and joined thereto by conventional tipping 16.
The smoker rolls the sheet 12 of reconstituted tobacco into a
cylinder of slightly smaller diameter than the hull 10, and
inserts the rolled sheet into the open end of the cylinder 14 of
the hull 10, as shown in the drawing. The smoker pushes the
rolled sheet 12 into the hull, so that the sheet abuts the
filter. The assembled smoking article can be smoked as a
conventional smoking article.
In another embodiment, not shown, the smoker rolls cut filler in
a sheet of smoking material, such as a sheet of reconstituted
tobacco, and inserts the thus formed rod into the hull of
cigarette wrapper. - -
