Then, the functions and effects of the medicated cigarette 1 of present embodiment are illustrated.In smoking cigarettes 1, if in tobacco rod
2 main flumes for producing are flowed into filter plug 4, main flume when by filtering the filtering material 41 in section S1, tar and
Filtered into branch in the cigarettes such as nicotine.Further, since the CO being contained in main flume is gas phase composition, therefore, will not be by
Filtering material 41 is filtered.Because the passage 31 for being arranged in the joint scraps of paper is configured with the filtration section S1 of filter plug 4, lead to
Cross air that passage 31 is imported into and mixed by filtering the main flume of section S1.Thus, composition in the cigarette of main flume
It is diluted, is contained in the tar of main flume, nicotine, CO etc. and reduces.
But, the filter plug 4 of present embodiment takes low filtration highly diluted design, i.e. from the air that passage 31 is imported
Dilution and the low filtration highly diluted of the Balancing relization between the filtration of filtering material 41.More specifically, by filter plug 4
The interval configuration in local there is no the section of the function of filtering main flume, i.e. leading portion section S2 and suction nozzle end section S3, so as to
Realize low filtration highly diluted.
Here, leading portion section S2 and suction nozzle end section S3 be provided with respectively with hollow form the first medium pore 42a and
The medium pore filter plug 42,43 of the second medium pore 43a.It is first central except hollow form in the cross section of medium pore filter plug 42
Region beyond the 42a of hole is compressed into the fibre bundle of shape and occupies.Therefore, on the cross section of medium pore filter plug 42, fibre bundle
The aeration resistance in the region for occupying is it may be said that the big many of aeration resistance than the first medium pore 42a.Equally, medium pore filter plug 43
In cross section in the region in addition to the second medium pore 43a of hollow form be compressed into the fibre bundle of shape and occupy.Therefore, exist
On the cross section of medium pore filter plug 43, the aeration resistance in the region that fibre bundle is occupied is it may be said that more logical than the first medium pore 43a
The big many of atmidometer.Therefore, the main flume for having passed through to filter section S1 flows successively through the first minimum medium pore of aeration resistance
42a and the second medium pore 43a, is finally attracted in oral cavity from suction nozzle end.So, in the filter plug 4 of present embodiment, only in mistake
Filter section S1 has the filtering function of composition in the cigarette for filtering main flume, follow-up leading portion section S2 and suction nozzle end section S3 not
With the filtering function to composition in cigarette.Thus, the balance of the dilution and filtration of main flume reaches low filtration highly diluted, can drop
Ratios of the low CO relative to tar.As a result, the smoking mouthfeel of medicated cigarette 1 strengthens, its fragrance can be lifted.
Further, from suppressing from the aspect of in smoking, tar is partly attached on the suction nozzle end face of filter plug 4, this reality
The medicated cigarette 1 for applying mode specifies that the magnitude relationship between the sectional area on two insertion roads is, the second medium pore 43a in suction nozzle end section S3
Sectional area it is bigger than the sectional area of the first medium pore 42a in leading portion section S2.Hereinafter, the comparative example with reference to shown in Fig. 4 and Fig. 5
Illustrate the filter plug 4 of present embodiment.
Fig. 4 is the profilograph of the filter plug 40 of comparative example.In filter plug 40, filtering material is continuously provided with from front
410 and medium pore filter plug 430.The filtering material 410 and medium pore filter plug 430 of filter plug 40 is substantially and present embodiment
Filter plug 4 filtering material 41 and medium pore filter plug 43 it is equal.That is, compared with from the filter plug 4 shown in Fig. 1, eliminate
Beyond leading portion section S2 (medium pore filter plug 42), the composition of the filter plug 40 of comparative example is substantially equal.
Suction with comparative example filter plug 40 medicated cigarette when, from tobacco rod side inflow to the main flume of filter plug 40 according to
The secondary medium pore 430a for flowing through filtering material 410 and medium pore filter plug 430 and be attracted in oral cavity.Fig. 5 is to show schematically
The figure of the local tar pollution on the suction nozzle end face of the filter plug 40 of comparative example.When the medicated cigarette of comparative example is aspirated, tar is easy
(edge part) around medium pore 430a on suction nozzle end face is attached to locally, and, the tar pollution on suction nozzle end face
Easily become obvious.
On the other hand, the filter plug 4 of present embodiment is by by the sectional area of the second medium pore 43a of suction nozzle end section S3
It is set as that the sectional area of the first medium pore 42a of the leading portion section S2 of upstream than being continuously arranged at suction nozzle end section S3 is big, energy
The tar pollution of the locality of (edge part) around the second medium pore 43a on suction nozzle end face is enough made to become to be difficult to discover.
That is, as shown in figure 1, in the filter plug 4 of present embodiment, positioned at the inboard leading portion section S2 of suction nozzle end face and
The boundary position of suction nozzle end section S3, the flow path cross sectional area of main flume increase (the first medium pore 42a → the second medium pore
43a).And, leading portion section S2 and suction nozzle end section S3 boundary position from the first medium pore 42a to the second medium pore 43a
During inflow, main flume extends to cross-sectional direction and flows into the second medium pore 43a.Therefore, after medium pore filter plug 42
End face, around the first medium pore 42a, (edge part) can produce the tar attachment of locality.However, as shown in figure 1, central authorities
The rear end face of hole filter plug 42 is configured in the position from the suction nozzle end face length of lateral extent suction nozzle end section S3 inwards.Therefore, have
Even if having the tar attachment that locality is produced around the first medium pore 42a of the rear end face in medium pore filter plug 42, Jiao
Oily pollution is also difficult to the advantage recognized by smoker.
Then, flow velocity (flow) difference of the main flume for the central side in the second medium pore 43a being flowed with outer circumferential side
Illustrate.The cross-sectional area of the second medium pore 43a is bigger than the first medium pore 42a, therefore, although in the second medium pore 43a
Heart side is overlapped in the axial direction with the first medium pore 42a, however, outer circumferential side is not but overlapped with the first medium pore 42a in the axial direction.Its
As a result, compared with the central side of the second medium pore 43a, the flow velocity (flow) of the main flume of periphery side region is relatively slack-off (to be become
It is few).So, by make the second medium pore 43a outer circumferential side flow main flume flow velocity (flow) reduce, can make from
The rear end of the second medium pore 43a is attracted to intraoral main flume and is reduced with the frequency of suction nozzle end contact.Therefore, it is possible to make
The tar attachment of the locality of (edge part) around the second medium pore 43a on suction nozzle end face is not allowed to be also easy to produce.As a result, energy
Enough suppress the tar pollution on the suction nozzle end face of filter plug 4, be allowed to be difficult to discover.
Further, according to present embodiment, need not arrange filter plug 4 cross section integrally become hollow (cavity) cavity or
The sections such as recess, it becomes possible to realize the low filtration highly diluted of filter plug 4.Accordingly, can be between the whole district of the length direction of filter plug 4
Prevent the not enough situation of hardness.Therefore, can suppress before smoking or occur during smoking the bad of 4 careless deformation of filter plug
Situation.As described above, according to the medicated cigarette 1 of present embodiment, making the tar pollution of the suction nozzle end face of filter plug 4 become to be difficult to examine
Feel, and can prevent the hardness of filter plug 4 not enough well.
Further, the filter plug 4 of present embodiment is set to the length of the length than leading portion section S2 of suction nozzle end section S3
It is short.Here, the thickness (wall thickness) of medium pore filter plug 43 is thinner than the thickness (wall thickness) of medium pore filter plug 42, therefore, by making
The length of medium pore filter plug 43 is shorter than the length of leading portion section S2, and the hardness deficiency that can be more reliably prevented from filter plug 4 is bright
It is clear.
In addition, in the present embodiment, the first medium pore 42a and the second medium pore 43a in filter plug 4 is configured to together
Axle.By this composition, the frequency of the main flume and suction nozzle end contact flowed out from the second medium pore 43a on suction nozzle end face can be made
Spend the second medium pore 43a it is whole around more uniformly reduce.As a result, Jiao on the suction nozzle end face of filter plug 4 can be made
Oily pollution becomes more to be difficult to discover.
Further, in the present embodiment, as the filtration section S1 in the leading section positioned at filter plug 4 is provided with filter material
Material 41, therefore, it can the cigarette for playing the filtering material 41 for preventing the tobacco shred 21 of tobacco rod 2 from entering in (spilling) filter plug 4
The effect of silk spillover alleviation unit.That is, the filtering material 41 for filtering section S1 is doubled as tobacco shred spillover alleviation unit.Tobacco shred overflows
As long as suppressing unit with the function of preventing tobacco shred 21 from entering in filter plug 4, filtering material 41 is just not limited to.Such as metal or tree
Mesh material etc. made by fat etc., can be using various compositions as tobacco shred spillover alleviation unit.However, such as present embodiment, leading to
Crossing makes tobacco shred spillover alleviation unit double as filtering material 4, it is possible to decrease the material cost of filter plug 4, and is prevented from manufacturing work
The complication of skill.
Further, in the present embodiment, the passage 31 of filter plug 4 is configured in position corresponding with section S1 is filtered.
By using this structure, having the advantages that swimmingly the air of ventilation can be directed in filter plug 4 from passage 31.
In addition, passage 31 is configured in filtration section S1.And, such as present embodiment, by passage 31 is configured at suction nozzle end
The upstream side of section S3, is made front using the flowing of the air of the ventilation (dilution) being directed in filter plug 4 from passage 31
Section section S2 the first medium pore 42a flowing main flume be close to first medium pore 42a central side and easily by.
That is, make from the flowing of 31 leaked-in air of passage to be close to the outer circumferential side of the first medium pore 42a, so that the flowing of main flume
The central side of the first medium pore 42a is close to, their downstream side flowings are made in this condition.This main flume and dilution are empty
The flowing of gas is still maintained in the second medium pore 43a by suction nozzle end section S3, therefore, further lifted central from second
The rear end of hole 43a is attracted to the effect of intraoral main flume and the frequency reduction of suction nozzle end contact.Therefore, it can make
Tar pollution on the suction nozzle end face of filter plug 4 becomes more to be difficult to discover.Above-mentioned " makes main flume be close to the first medium pore
The central side of 42a by " effect passage 31 can be configured by the upstream side of suction nozzle end section S3 in filter plug 4 and obtain
.
Accordingly it is also possible to the configuration example shown in Fig. 6 is like that, passage 31 is properly configured at corresponding to leading portion section S2
