CIGARETTE WITH HYGIENE SLEEVE, AND MANUFACTURING METHOD
THEREFOR
FIELD OF THE INVENTION
[0001] The invention relates to the field of the cigarette, and more
particularly to a
cigarette comprising a sanitary cap and a method for manufacturing the same.
BACKGROUND OF THE INVENTION
[0002] At present, the commercially available cigarettes are mostly packed in
cartons,
and one end of the filter tip of the cigarette faces towards the opening of
the carton. To
smoke the cigarette, people need to hold the filter tip and take the cigarette
out of the
carton for smoking by themselves or handing to others. Because the hands often
carry
with multiple bacteria, the bacteria are easily adhered to the filter tip of
the cigarette
when being taken out, and then introduced into the human body via smoking.
Thus, the
China Consumer Association released the sixth consumer warning on May 30,
2001, that
smoking is an important way illnesses be introduced in from the mouth.
[0003] To solve the above problem, a sanitary cap is designed on the part of
the filter tip
contacting the human mouth. For example, a cigarette comprising the sanitary
cap has
been disclosed by the Chinese patent application numbers CNI01588732 and
= CN102048239, the sanitary cap is able to completely enclose the whole
filter tip, and the
sanitary cap is processed into an upper part and a lower part that are
detachable from each
other. Before smoking, the upper part of the sanitary cap is taken out by
dragging a pull
head. This kind of cigarette comprising the sanitary cap is capable of
effectively solving
the pollution problem o f the filter tip of the cigarette, but the manufacture
process of the
cigarette is complicate, highly required, and time-consuming. In addition,
since the
1

CA 02915924 2015-12-17
conventional cigarette manufacturers are generally configured with the
wrapping device,
the cutting device, the adhesive coating device, and the packaging device that
are
indispensable in the cigarette manufacture, the current devices in the
conventional
cigarette manufactures cannot meet the requirements for producing the
specially designed
sanitary cap. If the new adaptive devices are introduced, a large amount of
investment on
the fixed assets is required, thus increasing the production cost.
SUMMARY OF THE INVENTION
[0004] In view of the above-described problems, it is one objective of the
invention to
provide a cigarette comprising a sanitary cap and a method for manufacturing
the same.
The cigarette of the invention can be manufactured on the existing cigarette
manufacturing devices.
[0005] To achieve the above objective, there is provided a cigarette
comprising a sanitary
cap. The cigarette comprises: a cigarette body, a filter tip in butt
connection with the
cigarette body, and a sanitary cap disposed on the filter tip. A tipping paper
having an
inner surface coated with an adhesive is wrapped around a periphery of an end-
to-end
contacted portion of the filter tip and the cigarette body to realize fixed
connection
between the filter tip and the cigarette body. The sanitary cap is a
cylindrical structure
having one end closed and is formed by wrapping a packaging material having a
rectangular plane shape around a circumference of a column-shaped filler.
Contact
surfaces of the packaging material and the filler are adhered by the adhesive.
The sanitary
cap is sleeved on one end of the filter tip free from being wrapped by the
tipping paper
and is removable from the filter tip along an axial direction thereof
[0006] As an improvement of the invention, an interval is configured between
the
sanitary cap and the tipping paper.
2

CA 02915924 2015-12-17
[0007] As an improvement of the invention, a diameter of the filler is the
same as a
diameter of the filter tip.
[0008] As an improvement of the invention, a lap edge of the packaging
material after
wrapping is adhered by the adhesive.
[0009] There is also provided a method for manufacturing the cigarette
comprising the
sanitary cap. The method comprises preparing the cigarette body and a finished-
filter tip,
and the method further comprises:
[0010] 1) preparing the column-shaped filler having the same diameter as the
finished-filter tip;
[0011] 2) cutting the packaging material into the rectangular plane shape for
preparing
the sanitary cap, and coating the adhesive on positions of the packaging
material that are
to be a middle part and a lap edge of the subsequently wrapped packaging
material, in
which a width of the middle part coated with the adhesive is smaller than or
equal to a
height of the column-shaped filler;
[0012] 3) placing the filler prepared in 1) between two finished-filter tips
to allow the
filler and the two finished-filter tips to form end-to-end contact in an axial
direction on a
same horizontal line, wrapping the packaging material prepared in 2) around
the
end-to-end contacted finished-filter tips and filler to connect the finished-
filter tips and
the filler together, and ensuring that the filler is disposed on the middle
part of the
packaging material during wrapping so as to yield a finished-filter rod;
[0013] 4) cutting the tipping paper and coating the adhesive on one side of
the tipping
paper;
[0014] 5) placing the finished-filter rod prepared in 3) between two cigarette
bodies to
allow the finished-filter rod and the two cigarette bodies to form end-to-end
contact in the
axial direction on the same horizontal line; wrapping two tipping papers
around
3

CA 02915924 2015-12-17
peripheries of end-to-end contact portions between the cigarette bodies and
the
finished-filter rod respectively to allow the cigarette bodies and the
finished-filter rod to
be in fixed butt connection, while avoiding each tipping paper from contacting
with the
packaging material wrapped on the finished-filter rod during wrapping, whereby
yielding
a semi-finished cigarette; and
[0015] 6) radially cutting the semi-finished cigarette at a middle part of the
finished-filter
rod to yield two finished-cigarettes comprising the sanitary cap.
[0016] Compared with the prior art, advantages of the invention are summarized
as
follows:
[001711. Compared with the prior art, the sanitary cap sleeved on the filter
tip of the
cigarette can be manufactured by the common production materials in cigarette
producing
enterprises by coating the adhesive and wrapping the packaging material. The
structure of
the cigarette of the invention has simple structure, simple manufacture
process, low
production cost, and convenient use, and is able to prevent the filter tip of
the cigarette
from pollution before smoking. The most obvious advantage is that the
cigarette of the
invention can be manufactured on the existing devices in the conventional
cigarette
producing enterprises. No additional devices are required and the working
process is
simple.
[0018] 2. As the filter tip contacts with the mouth during smoking, the
periphery of the
filter tip of the cigarette in the absence of the sanitary cap is required to
wrap a tipping
paper for sanitation, However, the tipping paper can only be used when it
reached more
than thirty national quality inspection standards, thus the tipping paper has
relatively high
price. Because the cigarette of the invention is protected by the sanitary
cap, it is not
necessary to wrap the tipping paper around the filter tip, thereby reducing
the production
cost of the cigarette.
[0019] 3. In the conventional method for preparing the cigarette, the two
cigarette bodies
4

CA 02915924 2015-12-17
and the filter tip therebetween are placed in end-to-end contact in the axial
direction at the
same horizontal line, wrapped, and cut by a cutting device at the middle of
the filter tip so
as to form to cigarette products. Because the cutter generates heat in
condition of long
term of fast working, it requires cooling oil to cool the cutter in the
manufacturing
process of the cigarette. However, the cooling oil remained on the cutter is
inevitably
adhered to the cross section of the filter tip during cutting, thus, a special
oil that is
harmless to the human body and therefore has a relatively high price must be
employed
as the cooling oil. In the cigarette and the manufacture method thereof
provided in the
invention, the cigarettes are cut by the cutter from the middle part of the
filler, which
does not result in any pollution and enables the method of the invention to
use the
common cooling oil to cool the cutter, therefore reducing the production cost
as well as
improving the safeness of the cigarette during smoking.
