Abstract

Provided is a heat-not-burn flavor inhalation article that is to be used with an electric heating device that comprises an inductor for electromagnetic induction heating. The heat-not-burn flavor inhalation article comprises: a flavor generation segment filler that includes an aerosol base material; a flavor generation segment that includes a plate-shaped susceptor for electromagnetic induction heating the flavor generation segment filler; and a mouthpiece segment for inhaling a flavor component. The compressive change rate of the flavor generation segment and the mouthpiece segment as measured in accordance with a specific compressive change rate measurement method by pressing an airflow-direction center part of each segment is at least 70%.

First claim

What is claimed is:

1 . A non-combustion-heating-type flavor inhalation article used with an electrical heating type device comprising an inductor for electromagnetic induction heating, the non-combustion-heating-type flavor inhalation article comprising:
a flavor-generating segment that includes a flavor-generating-segment filler containing an aerosol-source material and a plate-shaped susceptor for electromagnetic induction heating of the flavor-generating-segment filler; a mouthpiece segment for inhaling a flavor component; and a lining sheet that wraps at least a part of the flavor-generating segment and entire of the mouthpiece segment; wherein the mouthpiece segment comprises a cooling segment and a filter segment that are arranged downstream side of the flavor-generating segment in an airflow-direction, the lining sheet is formed of two sheets, the two sheets are consisting of a first sheet and a second sheet arranged downstream and outer side of the first sheet, the first sheet wraps entire of the flavor-generating segment and a part of the cooling segment, and the second sheet wraps at least entire of the filter segment and a part of the cooling segment, a compression change rate of each of the segments, as measured by pressing each airflow-direction central part of the flavor-generating segment and the mouthpiece segment of the non-combustion-heating type flavor inhalation article in accordance with a compression change rate measurement method below, is 70% or greater, where compression change rate measurement method: a load F of 2 kgf is applied to 10 or 20 samples simultaneously, the 10 or 20 samples being arranged side by side in a horizontal direction, from an upper side to a lower side by using a measuring instrument DD60A manufactured by Borgwaldt Co., Ltd.; after the load F has been applied for 5 seconds, an average of diameters of rod portions is measured; a compression change rate (%) is expressed by a formula below;
compression change rate (%)=100×( Dd (diameter after deformation))/( Ds (diameter before deformation))

where Dd stands for the diameter of each of the rod portions that has been reduced as a result of the load F being applied to the rod portion, and Ds stands for the diameter of each of the rod portions before the load F is applied; in the method, measurement is performed 10 times for each set of 10 or 20 samples, and an average value of results of the measurement performed 10 times is used as a measurement result.

2 . The non-combustion-heating-type flavor inhalation article according to claim 1 ,
wherein the flavor-generating-segment filler comprises at least one selected from tobacco leaves, shredded tobacco, a tobacco sheet, tobacco granules, a nicotine-carrying ion-exchange resin, and a tobacco extract.

3 . The non-combustion-heating-type flavor inhalation article according to claim 2 ,
wherein the flavor-generating-segment filler comprises a tobacco sheet, and the tobacco sheet is inserted in a gathered manner after being crimped.

4 . The non-combustion-heating-type flavor inhalation article according to claim 1 ,
wherein a filling density of the flavor-generating-segment filler in the flavor-generating segment is 0.2 g/cm 3 to 0.7 g/cm 3 .

5 . The non-combustion-heating-type flavor inhalation article according to claim 1 ,
wherein the mouthpiece segment further comprises a filter segment, and the filter segment comprises a filter element and wrapping paper wrapping the filter element, the wrapping paper having a thickness of 40 μm to 100 μm, and a basis weight of 23 gsm to 90 gsm.

6 . The non-combustion-heating-type flavor inhalation article according to claim 1 ,
wherein the mouthpiece segment comprises a cooling segment and a filter segment.

7 . The non-combustion-heating-type flavor inhalation article according to claim 5 ,
wherein the non-combustion-heating-type flavor inhalation article further comprises an end segment and a support segment, and the end segment, the support segment, and the filter segment contain cellulose acetate fibers.

8 . The non-combustion-heating-type flavor inhalation article according to claim 7 ,
wherein the end segment, the support segment, and the filter segment are each a solidified member containing cellulose acetate fibers and a plasticizer.

9 . A non-combustion-heating-type flavor inhalation product, the non-combustion-heating-type flavor inhalation product comprising:
the non-combustion-heating-type flavor inhalation article according to claim 1 ; and an electrical heating type device, wherein the electrical heating type device comprises
an inductor for electromagnetic induction heating,
a power source that supplies operation power to the inductor,
a control unit for controlling the inductor, and
a heating chamber into which the non-combustion-heating-type flavor inhalation article can be inserted via an insertion slot.
