ROLL-YOUR-C~WN CIaARET~ES
The present invention relates to novel structures
useful in the formation of "roll-your-own" cigarettes.
Ihe large majority of cigarettes are sold as pre-
formed cigarettes which can b~ smoked without further
assembly or processing by the consumer. A minority of
smokers prefer to assemble their o~n cigarettes, since
~obacco sold in ~n inherently-unsmo~eable form attracts a
much lower rate of tax than in pre-formed cigarettes and
hence is cheaper to purchase and the consumer is able to
smoke more cigarettes for the same p~ice.
A variety of procedures have been used to form roll-
your-own cigarettes, ranging from wrapping con~umer
assembled tobacco filler rods in cigarette paper to
inserting an inherently-unsmokeable pre-formed rod of
tobacco into a preformed filter-tipped paper tube ha~ing
a length to fully enclose the rod. In accordance with
the prese~t. invention, there are provided a~ditional
no~el ways of assembly of a cigarette for smoking.
In accordance wi~h an aspect of the lnvention, there
is pro~ided an inherently-unsmokeable cigarette
cornprising a tobacco rod and adjacent filter assembled in
wrappin~ ~here the wrapping about the filter has a
sufficiently high porosity to render the cigarette as
inherently-unsmokeable.
In accordance with another aspect of th~ invention,
there is provided a multiple of the inherently-
unsmokeable cigarette element~ packaged for sale where
each sold inherently-unsmckeable cigarette element may be
rendered smokeable by a s~oker applyi~g a suitable
coating ~eans to the sufficiently high ~rosit~ wrapping
about the filter.
In accordance ~ith another aspect of the invention,
there is provided a multiple of inherently-unsmokeable
cigarette elements and a suita~le coatin~ means for such
cigarette elements packaged for sale where each of the
5 4
-
_ la
inherently-unsmokeable cigarette elements comprises a
tobacco rod and adjacent filter assembled in wrapping
where the wrapping about the filter has a sufficiently
high porosity to render the cigarette element as sold as
inherently-unsmokeable and the suitable coating means
being for application ~y a smoker to the porous wrapping
about the filter of each of the cigarette elements to
render each ciga~ette ele~ent with coatins means applied
thereto by a smoker as a smokeable cigarette.
In accordance with another embodiment of the
invention, there is provided a method of forming a
cigarette for smoking, which comprises pro~iding a
cigarette rod comprising an outer cigarette wrapping
paper enclosing a tobacco filler rod for a ~ubstantial
proportion of the length thereof and defining a recess at
one end of the rod, and in~erting a cigarette smoke
filter into the recess to provide a cigarette.
In ~his embodiment of the invention, therefore, a
pre-portioned tube alre~dy containing a charge of cut
tobacco is provided which has an accommodation space for
a filter and a filter, usually the same length as the
accommodation space, is inserted into the filter
accommodation space to provide the finished cigarette.
Perforations may be provided in the wall of the
filter accommodation space to prevent the un-assembled
20112~4

The filter may be fixed in place following its
insertion into said recess by any convenient means,
usually an adhesive. The adhesive may be such that it
is normally dry on the outer surface of the filter and
may be moistened immediately prior to assembly into the
recess.
In accordance with another embodiment of the
present invention, there is provided a method of forming
a cigarette for smoking, which comprises providing an
elongate inherently dimensionally stable element made
only of smokeable material and having an air-permeable
outer surface whereby the element is unsmokeable in that
state, and coating the outer surface of the element with
a layer of smokeable material to render the element
smokeable.
In this embodiment of the invention, therefore, a
wrapped tobacco stick which has a wrapping which is
sufficiently porous as to prevent the stick from being
smoked or other means of rendering the stick inherently
unsmokeable is rendered smokeable by applying a suitable
coating to the porous wrap. The coating, which may be
of a wide variety of suitable materials, may be applied
in any convenient manner, for example, by dipping the
stick into a coating solution or by spraying the wrapper
surface with a coating solution, and drying the wetted
surface to a coating.
The inherently-unsmokeable tobacco element or stick
may take any of the forms described in Canadian Patent
No. 1,235,039. The charge of tobacco is usually
located within a wrapper which has a sufficiently high
porosity that the tobacco element cannot be smoked.
A tobacco smoke filter element may be attached to
one end of the tobacco element or may be attached to the
tobacco element following the coating step.
The tobacco element is rendered smokeable by
coating the outer surface of the tobacco element with a
- 2011254
-
suitable material which will form a smokeable coating on
the tobacco element.
In accordance with a further embodiment of this
invention, there is provided a method of forming a
cigarette, which comprises providing a plurality of
preformed elongate inherently dimensionally and
physically stable cut tobacco elements made only of
smokeable material and having an air permeable outer
surface whereby the element is unsmokeable in that
10 state, each of the elements having a length less than a
normal cigarette length and such that a multiple number
of the elements has a length corresponding to that of a
normal cigarette; providing a preformed cigarette paper
tube having a hollow interior; and sequentially
15 inserting individual ones of the plurality of tobacco
elements into the hollow interior of the preformed
cigarette paper tube to fill the same.
In this further embodiment of the invention,
therefore, multiple discrete short lengths of inherently
20 non-smokeable tobacco sticks are inserted seriatim -into
a preformed paper tube to abut each other in the tube.
The inherently unsmokeable tobacco element or stick may
take any of the forms described in Canadian Patent No.
1,235,039. The charge of tobacco usually is located
25 within a wrapper which has a sufficiently high porosity
that the tobacco element cannot be smoked.
Usually, each of the plurality of preformed tobacco
elements or sticks are of the same length, for example,
about 12 to 15 mm. The cut tobacco in the tobacco
30 elements or sticks may be the same tobacco blend or some
or all of the tobacco element may be different tobacco
blends.
The preformed cigarette paper tube generally
comprises a tubular cigarette paper wrapper having a
35 cigarette smoke filter located at one end thereof and
open to the hollow interior at the other. Such
2011254
~_ 4
preformed cigarette paper tubes are described in
Canadian Patent No. 1,235,039 referred to above.
In summary of this disclosure, the present
invention provides specific novel procedures for forming
roll-your-own cigarettes. Modifications are possible
within the scope of this invention.
