We, OLIN MATHIESON CHEMICAL CORPOR-
ATION, a Corporation organised and existing
under the laws Of Like State of Virginia,
United States of America, of 460, Park
5Avenue, New York 22, New York, United
States of America, do hereby declare the in-
vcntion for which we pray that a patent May
be granted to us, and the method by which it
is to be performed, to be particularly de-
10scribed in and by the following statement:-
The present invention relates to cigarettes
and in particular to a tipped cigarette.
The term " tipped " cigarette is utiliscd to
denote that class of cigarettes, conventional
15or filter type, wherein a band of piper or
other tipping material is disposed about the
end of the cigarette which is introduced irato
the mouth of the smoker
For example, tipping may take the form of
20a paDer band simulating -a band of cork or
the like.
An -aim of the invention is the provision of
a tipped cigarette where the tipping material
is formed with a plurality of openings of such
25small size that they are not obvious and are.
scarcely perceptible to normal vision.
According to the invention there is pro-
vided a cigarette comprising a column of
tobacco, a wrapper encircling the column of
30tobacco, and a band of tipping material
encircling the wrapper at one end of the
cigarette, wherein said wrapper is formed
with at least one macroscopic opening, said
tipping material being formed with a plurality
35of microsmpic openings, the tipping material
being so disposed with respect to the wrapper
opening that at least some of the microscopic
openings fail in register with the wrapper
operung to provi 'dc communication from the
40atmosphere to the interior of the cigarette
through the tipping material and the wrapper.
Preferred embodiments of the invention
will now be described by way of example
with reference to the accompanying drawings,
45in which:-
(Price 4s. 6d.
Figure 1 shows a cigarette in which the
principles of the prescrit invention are
utilized;
Figure 2 is a showing of a portion of Ehc
cigarette of Figure I somewhat enlarged and 50
with portions broken away for clarity;
Figure 3 shows an alternative embodimpnt
of the invention wherein the wrapper ex-
tends the full length of the cigarette;
Figure 4 ilustrates an example of tipping 55
paper, and;
Figure 5 shows obvious openings in the
wrapper band.
Referring now to the drawings, specifically
Figures I and 2, there is shown a cigarette 60
indicated generally by the reference numeral
10 comprising a column of tobacco 11 cn-
closed by a wrapper 12 and including an
abutting filter plug 13.
The filter plug and the wrapper column of 65
tobacco are joined in abutting mlationsWp
by a band of 14 of tipping p6apcr in wall
known fashion.
The wrapper 12 is formed with a plurality
of openings 16 while the tipping paper in- 70
cludes an area or ribbon of obscure openings
(shown somewhat enlarged for clarity)
indicated by the reference numeral 17.
As is apparent in Figure 2, the tipping
paper is so disposed with respect to the 75
wrapper 12, that some of the openings in the
tipping paper fall into register with the
wrapper opening. In this fashion, there is
provided a conduit from the atmosphere to
the interior of the cigarette so that the 80
smoker upon taking a " drag" induces air to
enter the conduits.
A convenient way of chancterizing the
openings in the tipping and in the wrapper
and a convenient aid in defining the relative 95
size of the tipping openings as against the
wrapper openings is to refer to the former as
being microscopic in size while the latter
openings are macroscopic.
Furthermore, it is intended that the tip- 90

ping band be securely fim-A to the cigarette
body such as by blucing.
Figure 3 shows an alternative embodiment
of the invention wherein a wrapper 120
5having criacroscopic openings 160 is shown
enclosing a cclumn of tobacco 110 and a
filter plug 130 so that the wrapper extends
the full length of the body of the cigarette.
The tippitIg paper 140 shown jacketing the
10wrapper is formed with a band of micro-
scopic openings 170 which fall in rtgister
with the openings 160.
Obviously the plug 130 may be replaced
with tobacco so that a still further embodi-
15ment of the invention my be constructed so
as the embrace nothing but tobacco within
the wrapper portion the of.
Figures 4 and 5 show typical tipping
material in the form of paper band 18 having
20a ribbon of microscopic openings 19 and a
typical wrapper paper 21 having macroscopic
openings 22 respectively.
Obviously the width and finish-of the tip-
ping paper, indeed, the imterial from which
25the tipping is fabricated, is not critical.
Correspondingly, the size, number and
conformation of the holes 22 is not critical so
leng, as the cigarette embracing these
elements is constructed in accordance with
30the invention.
It is intended that a cigarette constructed
in accordance with this invention will be
effective when smoked to bring about the
introduction of air into the body of the
35cigarette through the lateral or side openings
formed in the tipping and in the wrapper in
addition to the normal draught of air that is
drawn longitudinally through the burning
cone and the column of tobacco of the
40cigarette.
Obviously a wide variety of opening struc-
turcs can be devised, i.e., the area of the
openings in the wrapper tiny be increased of
decreased to increase or decrease the volume
of air drawn thereto, without departing from 45
the invention.
WHAT WE CLAIM IS:-
I. A cigarette comprising a column of
tobacco, a wrapper encircling the column of
tobacco, and a band of tipping material 50
encircling the wrapper at one end of the
cigarette, wherein said wrapper is formed
with at least one macroscopic opening, Wd
tipping material being formed with a
plurality of microscopic openings, the tip- 55
ping material being so disposed with respect
least some of
register with
cominunica-
c interior of 60
ttic through the tipping material and
the wrapper.
2. A cigarette according to claim 1,
wherein the wraprcr is formed with a
plurality of macroscopic openings, the tipping 65
material being so disposed with respect to the
wrapper openings that at least some of the
microscopic openings fall in register with the
%Tapper openings.
3. A cigarette according to claim I or 2, 70
which includes a filter plug abutting the
column of tobacco, the tipping material
encircling the plug and part of the wrapper.
4. A cigarette according to claim I or 2,
