TECHNICAL FIELD
[0001] The present disclosure belongs to a heat-not-burn (HNB) cigarette field, and in particular,
to an aerosol generating product with a composite plugging part.
BACKGROUND
[0002] With increasing attention of consumers to health and increasing demand for personalized
experiences of cigarette products, the tobacco industry has continuously responded
to upgrading of consumers' needs, various smoking products with tar reduction have
been developed so as to bring less harm to consumers. Among which, because of different
heating methods compared with traditional cigarette products, heating cigarettes can
provide a healthier smoking experience while meeting consumers' sensory needs for
cigarette products.
[0003] The existing integrated aerosol generating products include outer sleeves and aerosol
generating matrix filled in the outer sleeves, as well as other units for cooling
and circulating aerosol. At present, the aerosol generating matrix of integrated aerosol
generating products is usually granular aerosol generating material, as bulk aerosol
generating granules cannot be fixed, they must be filled into the outer sleeve by
filling, besides, both sides of the aerosol generating granule section are sealed
by sealing paper and plugging part to fix granules, while in order to gather aerosol
and increase the amount of smoke, the downstream of the plugging part is usually a
section of hollow cavity (a hollow cavity section) limited by the outer sleeve, and
the downstream of the hollow cavity section is a filtering section. At present, the
above aerosol generating products are prepared by filling, the production process
order is as follows: one end of the tube is sealed, while the aerosol generating matrix,
the plugging part and the filtering part are sequentially filled from the other end,
when filling the filtering part, a hollow cavity distance between the filtering part
and the plugging part is reserved, and the outer surface of the plugging part and
the filtering part is not glued to the inner wall of the paper tube, after direct
filling to a fixed position, they are fixed by friction with the inner wall of the
paper tube. Problem of the above filling method are as follows: 1. The tube is placed
vertically during filling, and it is difficult to locate positions of the plugging
part and the filtering part on both sides of the hollow cavity, resulting in inconsistent
axial lengths of the hollow cavity section of different samples; 2. As the outer surface
of the plugging part and filtering part and the inner wall of the paper tube are fixed
only by friction, during transportation, the plugging part and filtering part are
easy to move toward the hollow cavity section, or the filtering part is partially
sucked out of the outer sleeve during smoking; 3. The filling method is limited in
that it can only be filled in batches for individual tubes, resulting in low production
efficiency.
[0004] Moreover, the existing plugging parts are usually multi-hole firmware sections (commonly
known as "gears"), the multi-hole firmware sections are usually made of ceramic or
silicone, the outer wall is firmly bonded to the inner wall of the paper tube by binder,
and at least one axial through-hole is provided in the center, and / or, at least
one peripheral ventilation groove is provided on the periphery, and their size can
let smoke pass through while preventing aerosol source-material granules from passing
through, not only blocking aerosol source-material granules but transferring aerosols.
[0005] However, existence of multi-hole firmware sections brings more costs and operational
inconveniences to industrial manufacturing of granular aerosol generating products,
thus, those skilled in the art have been hoping to eliminate the multi-hole firmware
section. However, once eliminating multi-hole firmware sections, there is a dilemma
that an airflow channel must be set in the downstream of the granule section to collect
and accommodate aerosol, and the section can also constrain scattered aerosol source-material
granules, thus, improvement is needed for design of the plugging part.
[0006] Therefore, efficient production of granular aerosol generating products with a hollow
cavity structure, while ensuring stability of the plugging part and filtering part
without moving, and replacing existing plugging parts with a gear structure are key
problems to be solved in production of integrated aerosol generating products.
[0007] The present disclosure is proposed to solve the problems above.

surface of the plugging part 2, and the inner layer 212 limits the tube cavity 22;
A convergent sheet rod 221 is provided inside the tube cavity (22). That is, the plugging
part 2 of the present disclosure has its own outer layer 211 instead of taking the
outer sleeve 1 as the outer layer.
[0009] Preferably, the convergent sheet rod 221 is formed by converging sheet materials,
the volume of the convergent sheet rod 221 accounts for 30-80% of that of the tube
cavity 22, i.e., the filling amount of the sheet material in the tube cavity 22 is
30-80 %. Convergence can either be out of order or with order and regularity.
[0010] Preferably, the sheet materials include heat-shrinkable and non-heat-shrinkable materials.
The heat-shrinkable materials are selected from polymer materials or cellulose acetate,

structure.
[0012] In the actual selection process, if folded sheets are needed, non-woven fabrics are
preferred; if smooth sheets are needed, paper is preferred. In addition, preferably,
the groove corrugated sheet should be pre-pressed to form groove creases, and wrapped
with the outer layer 211 and the inner layer 212 to form the tube wall of the groove
corrugated structure. Correspondingly, during preparation of the convergent sheet
rod 221 in the tube cavity, the sheet material is pre-pressed to form creases and
converge, so as to facilitate converging.
[0013] Preferably, the cross section of the groove in the groove corrugated layer 213 is
of a "U" type or "V" type.
[0014] Preferably, the groove corrugated layer 213 is also provided with an aroma-enhancing
material layer and / or a smoking material layer, it can be selected from commonly-used
flavors, fragrances or smoking agents, e.g., the aroma-enhancing materials are selected

from propylene glycol and glycerol.
[0015] Preferably, the hollow cavity structure 3 is also provided with functional materials;
and / or, the hollow cavity structure 3 is also provided with an empty-tube part 32.

polylactic acid and non-woven fabric. Functional materials can be any form of material
with cooling and aroma-enhancing function in the prior art.
[0016] Preferably, an air vent 31 that axially penetrates the outer sleeve 1 is provided
on the outer sleeve 1 in the hollow cavity structure. When an empty-tube part is provided
inside the hollow cavity section 3, an air vent 31 penetrates through the outer sleeve
1 and the empty-tube part. The air vent 31 is to introduce air into the hollow cavity
section, so as to reduce aerosol temperature and suction resistance, thus, determine
whether the air vent 31 is needed according to the actual aerosol temperature and
suction resistance. When it is necessary to set the air vent 31, preferably by penetrating
through. Certainly, except for penetrating through, it is also possible to use permeable
paper as the outer sleeve or the empty paper tube in the hollow cavity section, as
long as air can be introduced into the hollow cavity section.
[0017] Preferably, there is a binder between the outer surface of the plugging part 2 and
the inner surface of the outer sleeve 1, and there is a binder between the outer surface
of the filtering part 4 and the inner surface of the outer sleeve 1. The binder is
selected from ordinary lap adhesive.
[0018] Preferably, the outer sleeve 1 is made of paper and non-woven fabric. The anti-seepage

foil layer, which is added to the inner wall of the cigarette paper tube by paste;
the aluminum foil layer can play the role of water-proof and / or oil-proof, but also
conducting and preserving heat, so that the smoking material on the inner wall of
the cigarette is evenly heated.
[0019] Preferably, the water-proof layer and / or oil-proof layer are coated on the inner
wall of the cigarette paper tube by spraying.
[0020] As moisture in the smoking material during cigarette storage seeps to the outside
of the cigarette paper tube and results in yellow spots, it is necessary to add a
water-proof layer to the inner wall of the cigarette paper tube filled with smoking
material. The water-proof layer is made of AKD, cationic rosin gum or non-iron aluminum
sulfate mix and paraffin material, so as to prevent moisture in the smoking material
from seeping to the outside of the cigarette paper tube.
[0021] Similarly, smoking agents, flavors and fragrances are added to smoking materials,
during long-term placement, smoking agents in the smoking materials may carry flavors
and fragrances to seep to the outside of the paper tube, resulting in yellow spots
and affecting appearances of paper tubes, as smoking agents are oily, it is necessary
to add an oil-proof layer to the inner wall of the cigarette paper tube filled with
smoking materials. The oil-proof layer is made of fluorocarbon organic matter, modified
starch, AKD and paraffin mixture, AKD and modified starch mixture, so as to prevent
smoking agents in smoking material carrying flavors and fragrances to seep to the
outside of the paper tube and occurrence of yellow spots.

[0035] That is, the filter-tip rod in step 1 can be a single filter tip, i.e., the outer
sleeve 1 includes a plugging part 2, a hollow cavity section 3, a filtering part 4

[0043] Compared with the prior art, the present disclosure has the following beneficial
effects:
- 1. The outer layer of the plugging part of the present disclosure is a groove corrugated
tube wall, the axial hollow cavity formed by the groove structure can be used as an
airflow channel for aerosol circulation, further, an aroma-enhancing material layer
and/ or a smoking layer is provided on the groove corrugated layer 213, to further
supplement aroma of the aerosol passing through and increase smoke amount. The multi-layer
groove corrugated layers support each other, so that more airflow channels can be
reserved as much as possible while ensuring plugging of aerosol generating materials.
The present disclosure eliminates the multi-hole firmware section for the first time,
combining the groove corrugated part with the bulk aerosol source-material granules,
as the tube wall of the groove corrugated structure and the plugging structure in
the tube cavity can play the role of constraining of aerosol source-material granules,
the multi-hole firmware is not needed.
- 2. A convergent sheet rod 221 is provided in the tube cavity of the plugging part
of the present disclosure, the volume of the convergent sheet rod 221 accounts for
30-80% of that of the tube cavity 22, the convergent sheet rod can block granular
aerosol generating materials, but also reserve more airflow channels as much as possible.
Further, the convergent sheet rod divides the central hollow cavity into a plurality
of airflow channels, which can disperse aerosol, and the large contact area between
the sheet rod and aerosol can facilitate reduction of aerosol temperature. The structure
can ensure the effect of plugging, cooling and resistance at the same time. More importantly,
the volume of the convergent sheet rod 221 of the present disclosure accounts for
30-80% of that of the tube cavity 22 (before smoking), when exceeding the filling
amount, suction resistance may increase greatly; when it is below the filling amount,
it is difficult to block aerosol generating materials while cooling aerosol.
- 3. In the preferred embodiment of the present disclosure, the convergent sheet rod
221 deforms when the temperature reaches 120°C. That is, during smoking, the convergent
sheet rod shrinks by heat and blocks part of central airflow, as the diameter of the
airflow channel changes, more aerosols flow into the groove corrugated structure of
the tube wall, and the groove corrugated layer 213 is also provided with an aroma-enhancing
material layer and / or a smoking material layer, so that more aerosols can be in
contact with aroma-enhancing materials and / or smoking materials, thereby further
improving effect of aerosol flavoring and increasing smoke amount.
[0044] As for the preparation method:
4. Each unit except the aerosol generating granule section is formed by rolling and
compounding in the present disclosure, a hollow cavity that can be filled with aerosol
generating material is reserved during compounding, cutting is carried out as needed
after compounding, and the filter rod filled with aerosol generating matrix accommodating
cavity 5 after cutting is placed vertically, the aerosol generating material is filled
into the aerosol generating matrix accommodating cavity 5, as both the plugging part
2 and the filtering part 4 are formed by compounding and rolling, it is easier to
locate the plugging part 2 and the filtering part 4 in the axial position, so as to
ensure consistency of axial lengths of the hollow cavity section 3 of different samples.
5. As the plugging part 2 and filtering part 4 are formed by compounding and rolling,
the binder can be more easily applied between the outer surface of the plugging part
2 and the filtering part 4 and the inner surface of the paper tube, so as to ensure
that no displacement occurs at both ends during smoking or transportation.
6. Compounding and then filling is used to prepare aerosol generating products in
the present disclosure, which can simultaneously compound a plurality of filter tips,
and filling the aerosol generating materials after cutting, except for the aerosol
generating material, other units are prepared by compounding, efficiency of each unit
is greatly improved compared with individual filling.
7. The flowing aerosol generating material is filled through squeezing in the present
disclosure, then the aerosol generating matrix accommodating cavity 5 is vertically
downward, place it on the plane to dry and expand at a certain temperature, so that
the aerosol generating material is solidified to form a fixed aerosol generating matrix
6 in the aerosol generating matrix accommodating cavity 5, production efficiency is
higher by squeezing, and the aerosol generating rod 6 obtained after drying and expansion
has a pore structure, which can facilitate release and circulation of aerosol. The
purpose of drying and expanding at a certain temperature on the plane after inversion
is to make the end face of the aerosol generating rod 6 away from the filtering part
even.

which is a volume reserved for expansion of the aerosol generating material.
[0060] In step 3, the drying temperature depends on the solvent in the aerosol generating
material, in this embodiment, the solvent is water, the drying temperature is 60°C,
with drying time of 1h.
[0061] The hollow cavity section 3 also includes an empty-tube part inside, which can be
made of paper. An air vent 31 that axially penetrates the outer sleeve 1 is provided

deforms when the temperature reaches 120-180°C. More preferably, deformation occurs
when the temperature reaches 120°C. That is, the plugging part 2 of the present disclosure
has its own outer layer 211 instead of taking the outer sleeve 1 as the outer layer.
[0067] The convergent sheet rod 221 is converged by heat-shrinkable materials. The heat
shrinkable materials are selected from polylactic acid. The volume of the convergent
sheet rod 221 accounts for 45% of that of the tube cavity 22, that is, the filling

Embodiment 2
[0071] The multi-sectional aerosol generating products are prepared in this embodiment according
to the preparation method 2, the differences between this embodiment and embodiment
1 are as follows: 1. In step 1, the filter-tip rod can be divided into four filter
tips, and the four filter tips are connected by the filtering part 4 and the aerosol
generating matrix accommodating cavity 5; at this time, there is also a cutting step
between step 1 and step 2, which is to cut at the connected filtering part 4 and the
connected aerosol generating matrix accommodating cavity 5, to cut the filter-tip
rod into four filter tips. The axial length of the filtering part at the joint is
twice that of the filter in a single filter tip, similarly, the axial length of the
aerosol generating matrix accommodating cavity reserved at the joint is twice that
of the aerosol generating matrix accommodating cavity in a single filter tip, so that
each filter tip has a complete set of a filtering part and an aerosol generating matrix
accommodating cavity after cutting. 2. In step 2, the flowing aerosol generating material
is filled into the aerosol generating matrix accommodating cavity 5 in two parts,
wherein, a first part of the aerosol generating material is squeezed into the aerosol

the aerosol generating material.
Embodiment 3
[0072] In the embodiment, the multi-sectional aerosol generating product prepared by the
preparation method 1, the structure of the plugging part in the aerosol generating
product is the same as that in embodiment 1, including the following steps:
Step 1, preparation of filter-tip rod:
An outer sleeve 1 is used to wrap a plugging part 2 and a filtering part 4, there
is a first axial length of the interval between the plugging part 2 and the filtering
part 4, the length is a hollow cavity section 3 limited by the outer sleeve 1,
One end of the plugging part 2 far away from the hollow cavity section 3 forms an
aerosol generating matrix accommodating cavity 5 limited by the outer sleeve 1.
Step 2, filling of the aerosol generating matrix 6:
The filter-tip rod is in a vertical state, wherein the aerosol generating matrix accommodating
cavity 5 is vertically upward, and the aerosol generating matrix 6 is filled into
the aerosol generating matrix accommodating cavity 5.
[0073] The filter-tip rod in step 1 is prepared in a horizontal state.
[0074] In step 2, the aerosol generating matrix 6 is granular. In this case, there is also
a sealing step after step 2, so that the aerosol generating matrix accommodating cavity
5 containing the aerosol generating matrix 6 away from the end face of the filtering
section can form a sealing film 7.
[0075] In step 1, the filter-tip rod can be divided into two filter tips, and the two filter
tips are connected by the aerosol generating matrix accommodating cavity 5; at this
time, there is also a cutting step between step 1 and step 2, which is cut at the
connected aerosol generation matrix accommodating cavity 5, to cut the filter-tip
rod into two filter tips. The joint has twice the axial length of the aerosol generating
matrix accommodating cavity 5, so that each filter tip has a complete aerosol generating
matrix accommodating cavity after cutting.
[0076] The hollow cavity section 3 also includes an empty-tube part inside, which can be
made of paper. An air vent 31 that axially penetrates the outer sleeve 1 is provided
on the outer sleeve 1 in the hollow cavity section 3. When an empty-tube part is provided
inside the hollow cavity section 3, the air vent 31 penetrates through the outer sleeve
1 and the empty-tube part.
[0077] There is a binder between the outer surface of the plugging part 2 and the inner
surface of the outer sleeve 1, and there is a binder between the outer surface of
the filtering part 4 and the inner surface of the outer sleeve 1.
[0078] The outer sleeve 1 is made of paper.
Embodiment 4
[0079] The multi-sectional aerosol generating products are prepared in this embodiment according
to the preparation method 1, the differences between this embodiment and embodiment
3 are as follows: 1. In step 1, the filter-tip rod can be divided into four filter
tips, and the four filter tips are connected by the filtering part 4 and the aerosol
generating matrix accommodating cavity 5; at this time, there is also a cutting step
between step 1 and step 2, which is to cut at the connected filtering part 4 and the
connected aerosol generating matrix accommodating cavity 5, to cut the filter-tip
rod into four filter tips. The axial length of the filtering part at the connection
is twice that of the filter in a single filter tip, similarly, the axial length of
the aerosol generating matrix accommodating cavity reserved at the connection is twice
that of the aerosol generating matrix accommodating cavity in a single filter tip,
so that each filter tip has a complete set of a filtering part and an aerosol generating
matrix accommodating cavity after cutting. 2. the aerosol generating matrix 6 in step
2 is paste-like, in this case, the sealing step is not needed.
Embodiment 5
[0080] The difference between this embodiment and embodiment 1 lies only in that, the volume
of the convergent sheet rod 221 in this embodiment accounts for 90 % of the volume
of the tube cavity 22, that is, the filling amount of the polylactic acid sheet in
the tube cavity 22 is 90 %.
[0081] Sensory evaluation is performed on the aerosol generating products prepared by embodiment
1 and embodiment 5, and the scores are shown in Table 1.
[0082] The basis is Q/YNZYJ07.022.

[0083] It can be seen from table 1 that, there are insignificant differences between aerosol
generating products in embodiment 1 and embodiment 5 in terms of fragrances, irritant
improvement, strength, harmony and taste, however, smoke amount of aerosol generating
products in embodiment 5 during smoking is far less than that in embodiment 1, the
reason lies in that, the volume of the convergent sheet rod 221 in embodiment 5 accounts
for 90% of that of the tube cavity 22, that is, the volume of the airflow channel
accounts for 10% before smoking, the convergent sheet rod 221 deforms by heat during
smoking, blocking most of the airflow channels, aerosol can only pass through the
groove corrugated structure of the tube wall, resulting in a significant decrease
in the smoke amount, the small amount of smoke may result in bad performances in fragrances,
irritant improvement, strength, harmony and taste. Besides, during smoking, sensory
evaluators also obviously feel that suction resistance of aerosol generating products
in embodiment 5 is large with poor smoking feeling. Thus, in actual smoking, deformation
of the convergent sheet rod 221 by heat may properly block part of the central airflow
channel, so that aerosol can pass through the groove corrugated layer to improve aroma-enhancing
effect, however, it may also lead to reduction of airflow channels; thus, it is necessary
to take into account effects of smoke amount and aroma enhancement. The volume of
the convergent sheet rod 221 in the present disclosure accounts for 30-80% of that
of the tube cavity 22.
