After filter tip makes cigarette, the cigarette 2 months conditions (condition G) are further stored with packaged configuration.To have passed through condition A
Each cigarette of~G implements the measurement to menthol amount in cigarette and tar content.
[table 4]
Table 4
Table 5 and Fig. 1 show the result of test.Reduced rate shown in table 5 be indicate with without implement filter tip storage and with
When the M/T ratio of the condition A of the storage of cigarette pack form compares, it is each under the conditions of M/T ratio reduced rate value.Fig. 1 is shown
The reduced rate of M/T ratio under the conditions of each.
[table 5]
Following result can be obtained according to table 5 and Fig. 1: the storage period of filter tip and with the storage period of the packaged configuration of cigarette
Between it is longer, the value of obtained menthol amount is smaller.In addition, the aeration resistance of confirmation filter tip is bigger, the reduced rate of M/T ratio is got over
Greatly, it is known that: reference example 2~4 is compared with the reference example 1 for meeting the essential condition of filter tip aeration resistance of claim 1, M/T
The reduced rate of ratio is big.It is thought that because, the filter tip of low pass atmidometer since tow weight is low, with high aeration resistance
Filter tip compare, absorption of the menthol to filter tip can be reduced, the release efficiency of per unit menthol amount is high.
It is confirmed by above result: by using the low filter tip of the aeration resistance of filter tip, readily and stably keeping cigarette
In menthol amount.It, can also be same by the high conditional combination of the low filter tip of aeration resistance and ventilation ratio
Ground obtains the effect, and the amount that can make menthol in cigarette increases, and the perfume (or spice) of menthol is also readily and stably kept after storage
Cigarette.
5~8 > of < reference example
Menthol flavoring amount in filter tip be set as every 1 contained in amount be 8mg or more in the case where, in order to verify
The amount of menthol becomes more stable in cigarette, and filter tip aeration resistance is set as constant, implements to change the menthol in filter tip
The test of flavoring amount and the storage period of filter tip.Table 6 shows the menthol flavoring amount in filter tip.It should be noted that
Herein also in the same manner as reference example 1~4, in order to remove the influence of other impact factors, it is not provided with venthole in filtering mouth, only
The aeration resistance of filter tip is changed, test is implemented.
[table 6]
The storage environment of filter tip is implemented, about filtering in the same manner as reference example 1~4 under 22 DEG C of temperature, humidity 60%
