Abstract

Provided are an aerosol generating article including a medium portion, and at least one filter portion, in which the filter portion is flavored, and the flavored filter portion is positioned in a tobacco end (TE) portion of the aerosol generating article, and an aerosol generating system including the same.

First claim

What is claimed is:

1 . An aerosol generating article comprising:
a medium portion; and at least one filter portion, wherein the filter portion is flavored, and the flavored filter portion is positioned in a tobacco end (TE) portion of the aerosol generating article.

2 . The aerosol generating article of claim 1 , wherein the flavored filter portion is positioned in both the TE portion and a mouth end (ME) portion.

3 . The aerosol generating article of claim 1 , wherein the filter portion comprises cellulose acetate (CA) and a plasticizer.

4 . The aerosol generating article of claim 1 , wherein the filter portion is flavored with a flavoring solution comprising a flavoring agent and a solvent.

5 . The aerosol generating article of claim 4 , wherein the flavoring agent comprises one or more selected from the group consisting of rosemary, eucalyptol, licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, mandarin oil, catechin, grapefruit, caraway, cognac, jasmine, menthol, ylang-ylang, sage, spearmint, ginger, coriander, and coffee.

6 . The aerosol generating article of claim 4 , wherein the solvent comprises one or more of propylene glycol (PG) and medium-chain triglyceride (MCTG) having 8 to 10 carbon atoms.

7 . The aerosol generating article of claim 6 , wherein the MCTG is included in a maximum amount of 0.6 mg in the flavored filter portion.

8 . The aerosol generating article of claim 1 , wherein the medium portion comprises one or more of reconstituted tobacco, cut tobacco leaves and tobacco granules.

9 . The aerosol generating article of claim 8 , wherein one of more of the reconstituted tobacco, cut tobacco leaves and tobacco granules are pH-treated to have a pH of 7.0 to 9.5.

10 . The aerosol generating article of claim 9 , wherein a pH treatment is a method of spraying a pH adjuster comprising one or more selected from the group consisting of potassium carbonate (K 2 CO 3 ), sodium bicarbonate (NaHCO 3 ), and calcium oxide (CaO) onto surfaces of one or more of the reconstituted tobacco, cut tobacco leaves and tobacco granules.

11 . The aerosol generating article of claim 8 , wherein one or more of the reconstituted tobacco, cut tobacco leaves and tobacco granules generate volatile free nicotine under non-heating conditions or under low-temperature heating conditions of 0° C. to 150° C.

12 . The aerosol generating article of claim 1 , wherein the flavored filter portion is positioned in both the TE portion and an ME portion, and
the flavored filter included in the ME portion comprises a maximum amount of 0.6 mg of MCTG.

13 . An aerosol generating system comprising:
an aerosol generating device comprising a battery, a controller, and a vaporizer; and an aerosol generating article comprising a medium portion and at least one portion, wherein the filter portion is flavored, and the flavored filter portion is positioned in a tobacco end (TE) portion of the aerosol generating article.

14 . The aerosol generating system of claim 13 , wherein
the aerosol generating device comprises a heater, and the heater does not heat the aerosol generating article or heats the aerosol generating article at a temperature of 0° C. to 150° C.
