Abrégé anglais

ABSTRACT
TOBACCO PRODUCT
There is disclosed a nicotine containing lozenge
prepared from a mixture of inert filler material, a
binder and either pure nicotine or a nicotine containing
substance by a technique not involving any application
of heat. Cold compression in a conventional tablet
making machine is preferred.

Revendications

CLAIMS
1. A method for the production of a nicotine con-
taining lozenge comprising the steps of thoroughly mixing
together an inert filler containing predominantly a sugar,
a binder and a solution in alcohol of either pure nicotine
or a nicotine containing extract and forming measured doses
of the mixture into a lozenge by a process not involving
the application of heat.
2. A method according to claim 1 wherein the measured
doses are formed into lozenges by compression.
3. A method according to claim 2 wherein said com-
pression is effected by a conventional tablet making machine.
4. A method according to claim 1, 2 or 3 wherein the
filler is predominantly comprised by one or more sugars.
5. A method according to claim 1 wherein the binder
is comprised by an aqueous solution.
6. A method according to claim 5 wherein the binder
includes acacia powder.
7. A method according to claim 1, 2 or 3 wherein the
nicotine is present as a tobacco extract or whole tobacco.
8. A method according to claim 1, 2 or 3 wherein
flavouring additives are incorporated.

Description

TOBACCO PRODVCT
,
This invention concerns a tobacco product, and
more particularly a nicotine containing lozenge which can be
dissolved in the mouth to satisfy a craving for tobacco,
either as an aid in stopping the habit of smoking or as a
substitute for cigarettes or other smokable tobacco products
in areas where smoking is dangerous or prohibited.
Previous attempts to produce a nicotine containing
lozenge have generally failed, since such attempts have fol-
lowed traditional confectionery making practice involving
the production of a hot syrup which has caused the highly
volatile nicotine oils to escape.
'rhe present invention is based upon an appreciation
of the possibility of producing a n~cotine con-taining
lozenge utilising the techniques customarily employed for
the production of peppermints.
According to the present invention there is pro-
vided a method for the production of nicotine containing
lozenges comprising the steps of thoroughly mixing together
an inert filler containing predominantly a sugar, a binder
and a solution in alcohol of either pure nicotine or a
nicotine containing extract and forming measured doses of the
mixture into a lozenge by a process not involving the
application of heat.

Preferably the tablet forming process is one of
cold compression wherein the measured close is compressed
and shaped between movable dies. Other possibilities
include extrusion or simply the drying out of doses of
mixture initially in a paste-like form.
Generally flavouring agents and possibly
colouring agents will be included in the mixture.
The invention also includes lozenges prepared by
the methods aforesaid.
The invention will be further apparent from the
following description which concerns, by way of example
only, a variety of possible mixes from which lozenges
may be prepared in accordance with the invention.
All lozenges embodying the invention are
prepared from a mixture of inert filler material, a
binder and either pure nicotine or a nicotine containing
substance.
The Filler
The possibilities for the inert filler which
will generally itself be a mixture of numerous
ingredients are numerous~

--3--
A preferred formulation is:-
Icing sugar 4800 gms
Lactose 2720 gms
Corn starch 400 gms
Cocoa powder 720 gms
Liquorice powder880 gms
Acacia powder 400 gms
Tragacanth 10 gms
Totalling 9930 gms
Numerous variations on this particular
formulation are, however, possible. For example, some,for instance 800 gms, of the icing sugar may be replaced
by dextrose. Again, for example, the relative
proportions of cocoa powder and liquorice powder may be
varied.
Generally, the exact formulation will be
determined by the end taste and texture desired.
~he Binder
; Again the possibilities for the binder are
limitless.
.~

9L~S~
A basic formulation is:-
Water 1 litre
Acacia powder 250 mls.
Amongst possible variations are, for example,
the addition of one or more of the following:-
Tragacanth, for instance 30 gms
Cofee powder, for instance 600 gms
Malic or other fruit acid - neutralised with
an hydroxide, for instance 50 gms
The water used in the preparation of the binder
may first be simmered for 20 minutes or so with 100 gms
of dried dill seeds or other herb or pIant if desired.
The Nicotine Preparation
The nicotine is preferably present as pure
nicotine dissolved in 40 ml of alcohol. The alcohol
may be Absolute or a commercially available liqueur or
spirit such as Crème de Menthe, Grand Marnier, whisky or
rum, for example. The quantity of nicotine used is
such as to give between 0.1 and 8 mg per lozenge,
preferably in the range of from 1 to 2 mg per lozenge.

7~
The nicotine preparation may be flavoured as desired with
oil of peppermint, wintergreen, spearmint or menthol, for
example.
The nicotine may, however, be present as whole
tobacco or a tobacco extract.
The filler and binder are thoroughly mixed,
dried and passed through a screen to remove all lumps or
the like. The nicotine preparation is dispersed into the
mixture which is then formed into lozenges of desired size,
preferably using cold compression tablet forming machinery
of known kind.
The resultant lozenges di.ssolve slowly in the
mouth releasiny the contained n:lcotine gradually for
absorption within the buccal cavity.
It will be appreciated that it is not intended
to limit the invention to the above example only, many
variations, such as might readily occur to one skilled in
- the art, being possible, without departing from the scope
thereof as defined by the appended claims.
l~r

For example, other additives .such as stimulants,
for instance caffeine, may be included if desirecl.
Other filler materials might be used including,
for example, magnesium stearate, sodium alginate, sodium
pectate, a cellulose product such as methyl cellulose
and sta~ches.
