Since each of the second outer wall holes 40b1 to 40b3 has the same configuration except for the position where it is disposed, in the present embodiment, the second outer wall holes 40b1 to 40b3 are simply indicated as the second outer wall holes 40b as appropriate. .

(3) Operation and Effect As described above, the non-heating type flavor inhaler 1 according to the present embodiment fills the cylindrical member 10 having the outer wall 11 that forms the cavity 15 and the cavity 15 of the cylindrical member 10. Flavor source 30 to be used.

  The tubular member 10 has a first end 21 through which air flows in and a second end 22 through which air flows out, and also includes a first outer wall hole 40a and a second outer wall hole 40b through which air flows. The first end 21 is provided with a first filter wall 51, and the second end 22 is provided with a second filter wall 52.

  Here, when the user starts sucking flavor from the non-heated flavor inhaler 1 in the state shown in FIG. 2, the flavor source 30 is directed toward the second end 22 side, which is the outflow destination of air. To move to the second filter wall 52.

  In the non-heating type flavor inhaler 1 according to the present embodiment, air flows into the cavity 15 of the tubular member 10 from the first end portion 21, the first outer wall hole 40a, and the second outer wall hole 40b. Therefore, when air flows only from the first end portion 21 of the cylindrical member 10, that is, when air flows only along the axis AX direction, the flow of air toward the second filter wall 52 is reduced. Inside, the flow of air along only the direction of the axis AX is suppressed.

  Further, the first outer wall hole 40a is a flavor source 30 filled in the cavity 15 in a state in which the axis AX direction is directed along the vertical direction Vd so that the second end 22 of the cylindrical member 10 is positioned below. Are provided at positions adjacent to each other.

  Here, the state in which the axis AX direction is directed along the vertical direction Vd so that the second end portion 22 is positioned below is a state in which the flavor source 30 simulates a state in which the flavor source 30 is most closely packed on the second filter wall 52. is there. That is, the 1st outer wall hole 40a is provided in the position adjacent to the flavor source 30 in the state which simulated the state where the flavor source 30 with which it was filled closely to the 2nd edge part 22 side.

  By providing the 1st outer wall hole 40a in the non-heating type flavor suction device 1 so that it may become the positional relationship mentioned above, it can suppress more reliably that the flavor source 30 concentrates on the 2nd filter wall 52. FIG. Specifically, by providing the first outer wall holes 40a1 to 40a3, at the time of flavor suction, in addition to the air flow along only the axis AX direction derived from the first end portion 21, it intersects with the axis AX direction. A flow of air along the direction is generated. Further, by providing the first outer wall holes 40a1 to 40a3, the flow of air derived from the first outer wall holes 40a1 to 40a3 becomes dominant, and as a result, the flow of air given to the flavor source 30 is changed from a plurality of directions. Can be given. Thereby, it is possible to prevent the flavor source 30 from being concentrated on the second filter wall 52 at the time of flavor suction.

  In other words, in the prior art, since only the air flow in the direction of the axis AX occurred, the flavor sources 30 were abruptly concentrated on the second filter wall 52, but in the present embodiment, as described above, the first By providing the 1 outer wall holes 40a1 to 40a3, it is possible to generate an air flow along a direction different from the direction of the axis AX, and thus it is possible to effectively suppress the concentration of the flavor sources 30 rapidly.

  Thus, according to the non-heating type flavor inhaler 1, it is possible to suppress the rapid movement of the flavor source 30 to the second filter wall 52 and the rapid congestion near the second filter wall 52 at the start of flavor suction. .

  That is, according to the non-heating type flavor inhaler 1, it is possible to suppress a sense of discomfort given to the user by the movement of the flavor source at the start of flavor suction.

  3, the distance Lb between the second filter wall 52 and the first outer wall hole 40a in the axis AX direction is preferably in the range of 0.5 mm or more and 5.0 mm or less. More preferably, it is 7 mm or more and 2.0 mm or less.

  Here, the air flowing into the cavity 15 of the tubular member 10 flows in from the first end portion 21, the first outer wall hole 40a, and the second outer wall hole 40b, but most of the air flowing into the cavity 15 is plural. Of the first outer wall holes 40a1 to 40a3, the first outer wall hole 40a1 is located closest to the second filter wall 52 side. Therefore, in order to reduce the impact caused by the flavor source 30 during suction, it is preferable to provide the first outer wall hole 40a as close to the second filter wall 52 as possible so as to reduce the distance Lb.

  On the other hand, the air flowing from the first outer wall hole 40a to the second filter wall 52 and the flavor source 30 can effectively contact each other by keeping the distance between the first outer wall hole 40a and the second filter wall 52 at a certain level or more. As a result, a suitable amount of flavor can be supplied into the oral cavity. Therefore, in this embodiment, it is preferable that the distance Lb is 0.5 mm or more.

  If the distance Lb is 5.0 mm or less, the air flowing in from the first end portion 21 and the air flowing in from the first outer wall hole 40a do not merge at a position away from the second filter wall 52. The air flowing in the direction intersecting the axis AX direction is likely to be generated in the vicinity of the second filter wall 52, and the air flow along only the axis AX direction can be more reliably reduced. That is, in order to effectively disperse the air flow focused on the second filter wall 52, the distance Lb is preferably 5.0 mm or less.

(4) Comparative evaluation 1
Next, comparative evaluation of the non-heating type flavor inhaler according to the present embodiment will be described. First, the non-heating type flavor inhaler according to Examples 1 and 2 and the non-heating type flavor inhaler according to Comparative Example 1 were prepared.

  As Example 1, an unheated flavor inhaler having the shape shown in FIGS. 1 and 2 was produced. Specifically, a plastic molded body was used as the cylindrical member 10, and mesh members were used as the first filter wall 51 and the second filter wall 52. The cylindrical member 10 includes a cylindrical outer wall 11 having a length of 42 mm in the vertical direction (AX direction) and protrusions 21a and 22a each having a length of 4 mm in the vertical direction. Moreover, the tobacco powder grain which shape | molded the tobacco leaf was used as a flavor source. The flavor source was filled so that the distance from the second filter wall 52 to the upper end of the flavor source was 25 mm when the second end portion 22 was left to stand below the vertical direction.

  In the first embodiment, a plurality of first outer wall holes 40 a and a plurality of second outer wall holes 40 b are provided on the tubular member 10. In addition, the distance between the first outer wall hole 40a1 (hereinafter also referred to as the nearest first outer wall hole 40) closest to the second filter wall 52 and the second filter wall 52 among the plurality of first outer wall holes 40a. The nearest first outer wall hole 40a1 was formed in the tubular member 10 so that Lb was 1.0 mm. Further, at the same time when the nearest first outer wall hole 40a1 is formed, the nearest first outer wall hole along the axis AX direction of the tubular member 10 extends from the nearest first outer wall hole 40a1 to immediately before the first filter wall 51. A plurality of first outer wall holes 40a and a plurality of second outer wall holes 40b other than 40a1 were formed. Each of the plurality of first outer wall holes 40a and the plurality of second outer wall holes 40b was provided such that the distance (pitch) between the centers of the holes had an interval of 2.0 mm. In this way, a plurality of first outer wall holes 40 a and a plurality of second outer wall holes 40 b are provided in a predetermined region of the tubular member 10. Similarly, the plurality of first outer wall holes 40 a and the plurality of second outer wall holes 40 b are further provided in a row on the opposite side of the outer wall 11 of the cylindrical member 10 with respect to the axis AX of the cylindrical member 10. That is, the non-heating type flavor inhaler of Example 1 has two rows of a plurality of first outer wall holes 40a and a plurality of second outer wall holes 40b. In addition, each diameter (hole diameter) of the some 1st outer wall hole 40a and the some 2nd outer wall hole 40b was 0.5 mm.

  Further, as Example 2, a non-heated flavor inhaler in which the position of the nearest first outer wall hole 40a1 was changed so that the distance Lb from the second filter wall 52 was 10.0 mm was produced. In addition, Example 2 has the same configuration as that of Example 1 except for the configuration of the distance Lb.

  Moreover, as Comparative Example 1, a non-heating type flavor suction device in which the first outer wall hole 40a and the second outer wall hole 40b were not formed was produced. Note that Comparative Example 1 has the same configuration as that of Example 1 except that the first outer wall hole 40a and the second outer wall hole 40b are not formed.

(Measurement of ventilation resistance)
Using the method according to ISO 6565-1997 Draw resistance of cigarettes and pressure drop of filter rods, the ventilation resistance of the non-heated flavor inhalers of Examples 1 and 2 and Comparative Example 1 was measured. Specifically, when viewed from the upstream side of the flowing air, devices were connected in the order of a non-heated flavor suction device, a differential pressure gauge, a mass flow controller, and a vacuum pump. And it attracted | sucked with 1050 ml / sec with the vacuum pump, and the ventilation resistance of each non-heating type flavor suction device was measured. The measurement results are shown in Table 1.

(Sensory evaluation of impact during suction)
Using the flavor inhalers of Examples 1 and 2 and Comparative Example 1 described above, a flavor suction operation was performed on 20 evaluators, and a sensory evaluation test was performed on each non-heated type flavor inhaler. Specifically, a sensory evaluation test was performed to evaluate the impact derived from the flavor source during the non-heating type flavor suction operation. The results are shown in Table 1.

   As is clear from the evaluation results of Table 1 above, there are a large number of evaluators who answered that the impact was anxious in Comparative Example 1, whereas in Examples 1 and 2, the evaluation was that the impact was not anxious. The number of people became large. Thus, in Examples 1 and 2, it was proved that the effect of suppressing the uncomfortable feeling caused by the impact was superior to that of Comparative Example 1. In addition, it was proved that Example 1 was able to more effectively suppress the uncomfortable feeling caused by the impact during the suction operation compared to Example 2.

As is apparent from the results of the ventilation resistance measurement, when mesh is used as the first and second filter walls, the non-heating type flavor inhaler having the first outer wall hole 40a and the second outer wall hole 40b is It can be seen that it has a ventilation resistance of 15.0 mmH ₂ O or less.

(Measurement of ventilation resistance fluctuation during suction operation)
Then, the non-heating type flavor suction device of Example 1 and the non-heating type flavor suction device of the comparative example 1 were used, and the change of ventilation resistance at the time of suction operation in each non-heating type flavor suction device was measured.

  First, a test apparatus was prepared. Specifically, a mass flow controller (SEC-B40, manufactured by Horiba ESTEC Co., Ltd.), a solenoid valve (manufactured by AG-43-02-4 CDK), between a vacuum pump (linicon lv660 manufactured by Nitto Kohki Co., Ltd.) and a flavor suction device. By arranging the differential pressure gauge (DP45-28 validine engineering corporation) in order from the vacuum pump side (downstream side of the system) and connecting the differential pressure gauge to the data logger (NR600 Keyence) and PC, A test apparatus that can visualize changes with time was prepared.

  In addition, in a state where the electromagnetic valve of the test apparatus is closed, that is, in a state where air inflow from each non-heated flavor suction device to the vacuum pump is suppressed, the air suction output of the vacuum pump is stabilized at 5 L / min. Adjusted. Thereafter, air was sucked from the flavor suction device by releasing the electromagnetic valve. At this time, using a differential pressure gauge, the change in ventilation resistance with time immediately after air suction was measured. The measurement results are shown in FIG.

  As is clear from FIG. 4, in the non-heated flavor inhaler of Comparative Example 1, a large decrease in ventilation resistance and a recovery behavior of the decrease are observed within 0.1 second from the start of suction. On the other hand, in the non-heating type flavor inhaler of Example 1, there is no such large fluctuation | variation of ventilation resistance, etc., and it turns out that very stable ventilation resistance is shown immediately after the suction start. Since the impact derived from the flavor source occurs immediately after the start of suction, it can be said that the difference in the temporal change in the ventilation resistance led to the difference in the results of the sensory evaluation described above. That is, it has been proved that the present invention is excellent in the effect of suppressing the fluctuation amount of the ventilation resistance within an extremely short time of 0.1 seconds after the start of suction.

(5) Comparative evaluation 2
Next, a sensory evaluation test was performed on the non-heated flavor inhaler by changing the configuration of the first filter wall and the second filter wall. First, the non-heating type flavor suction device of Examples 3 and 4 and Comparative Example 2 was prepared.

  Specifically, as Example 3, a non-heating type flavor inhaler using an acetate filter for the first filter wall and the second filter wall was produced. Example 3 has the same configuration as that of Example 1 described above, except for the configuration of the first filter wall and the second filter wall.

  Next, as Example 4, a non-heated flavor inhaler using an acetate filter for the first filter wall and the second filter wall was produced. Example 4 has the same configuration as that of Example 2 described above, except for the configuration of the first filter wall and the second filter wall.

  Next, as Comparative Example 2, a non-heating type flavor inhaler using an acetate filter for the first filter wall and the second filter wall was produced. Comparative Example 2 has the same configuration as Comparative Example 1 described above except for the configuration of the first filter wall and the second filter wall.

  In Examples 3 to 4 and Comparative Example 2, the acetate filters used for the first and second filter walls both have a thickness of 5 mm with respect to the axis AX direction of the non-heated flavor inhaler. It was.

(Sensory evaluation of impact during suction)
Using the flavor inhalers of Examples 3 and 4 and Comparative Example 2 described above, 20 evaluators were allowed to perform a flavor suction operation, and a sensory evaluation test was performed on each non-heated flavor inhaler. Specifically, a sensory evaluation test was performed to evaluate the impact derived from the flavor source during the non-heating type flavor suction operation. The results are shown in Table 2.

As is clear from the results of Table 2 above, even in the case where acetate filters are used as the first and second filter walls, in Examples 3 and 4, the impact during the suction operation is extremely effectively reduced. It was proved. That is, it has been proved that the non-heated flavor inhaler having the first outer wall hole 40a and the second outer wall hole 40b extremely effectively reduces the impact during the suction operation. In addition, it was proved that Example 3 was able to more effectively suppress the uncomfortable feeling caused by the impact during the suction operation compared to Example 4. In addition, when an acetate filter is used as the first and second filter walls, the non-heated flavor inhaler having the first outer wall hole 40a and the second outer wall hole 40b has a ventilation resistance of 25.0 mmH ₂ O or less. It can be seen that
