Abstract

Claims (54)

1. A method for producing a subunit of a Heat Not Burn (HNB) smoking article, comprising:

arranging a tubular body on an end face of a rod-shaped body; and

attaching the tubular body to the rod-shaped body,

wherein attaching the tubular body to the rod-shaped body comprises adhering a cover strip to the tubular body and to the rod-shaped body such that the cover strip attaches the tubular body to the rod-shaped body;

wherein arranging the tubular body on the end face of the rod-shaped body comprises arranging a double-length tubular body between the end face of the rod-shaped body and a corresponding additional end face of an additional rod-shaped body,

wherein attaching the tubular body to the rod-shaped body comprises attaching the double-length tubular body to the rod-shaped body and to the additional rod-shaped body, and

wherein, after attaching the double-length tubular body to the rod-shaped body and to the additional rod-shaped body, the method further comprises:

cutting the double-length tubular body down a center of the double-length tubular body;

wherein attaching the double-length tubular body to the rod-shaped body and to the additional rod-shaped body comprises attaching the double-length tubular body to the rod-shaped body and the additional rod-shaped body via a double-width cover strip;

wherein cutting the double-length tubular body down the center of the double-length tubular body comprises:

orienting a longitudinal axis of the double-length tubular body horizontally when cutting double-length tubular body down the center of the double-length tubular body; and

cutting the double-length tubular body into two separate pieces and to produce two separate structures,

wherein a first piece of the two separate pieces is the tubular body and a first structure of the two separate structures is the tubular body attached to the rod-shaped body, and

wherein a second piece of the two separate pieces is an additional tubular body, and a second structure of the two separate structures is the additional tubular body attached to the additional rod-shaped body;

orienting the tubular body attached to the rod-shaped body such that a longitudinal axis of the tubular body and a longitudinal axis of the rod-shaped body are vertically oriented, and a cavity of the tubular body is open at a top of the tubular body, which is above the rod-shaped body; and

filling the cavity of the tubular body with a filling material from above the tubular body.

2. The method according to claim 1 ,

wherein the cover strip is adhered to the tubular body and to the rod-shaped body over the entire surface of the cover strip.

3. The method according to claim 1 ,

wherein the rod-shaped body is a heat source, and

wherein the cover strip is adhered to at most 30% of a lateral surface area of the heat source.

4. The method according to claim 1 ,

wherein, prior to attaching the tubular body to the rod-shaped body, coating an inside of the tubular body with a metal and/or organic coating.

5. The method according to claim 4 ,

wherein the metal and/or organic coating is stable at temperatures of up to at least 350 degrees Celsius.

6. The method according to claim 1 ,

wherein the tubular body is made of cellulose.

7. A subunit of a Heat Not Burn (HNB) smoking article, comprising:

a rod-shaped body,

wherein the rod-shaped body has a cavity arranged thereon; and

a tubular body arranged on, and attached to, an end face of the rod-shaped body,

wherein the cavity of the tubular body is filled with a filling material,

wherein the subunit of the Heat Not Burn (HNB) smoking article is produced according to the method of claim 1 .

8. The subunit according to claim 7 ,

wherein the cover strip is adhered to the tubular body and to the rod-shaped body over an entire surface of the cover strip.

9. The subunit according to claim 7 ,

wherein the rod-shaped body is a heat source, and

the cover strip is adhered to at most 30% of a lateral surface area of the heat source.

10. The subunit according to claim 9 ,

wherein the cover strip is adhered to 20% to 30% of the lateral surface area of the heat source.

11. The subunit according to claim 7 ,

wherein the tubular body is coated on an inside of the tubular body with a metal and/or organic coating.

12. The subunit according to claim 11 ,

wherein the metal and/or organic coating is stable at temperatures of up to at least 350 degrees Celsius.

13. The subunit according to claim 7 ,

wherein the tubular body is made of cellulose.

14. A Heat Not Burn smoking article, comprising:

a subunit according claim to 7 .

15. The heat not burn smoking article according to claim 14 , wherein the cover strip is adhered to the tubular body and to the rod-shaped body over an entire surface of the cover strip.

16. The heat not burn smoking article according to claim 14 , wherein the rod-shaped body is a heat source, and the cover strip is adhered to at most 30% of a lateral surface area of the heat source.

17. The heat not burn smoking article according to claim 16 , wherein the cover strip is adhered to 20% to 30% of the lateral surface area of the heat source.

18. The heat not burn smoking article according to claim 14 , wherein the tubular body is coated on an inside of the tubular body with a metal and/or organic coating.

19. The heat not burn smoking article according to claim 18 , wherein the metal and/or organic coating is stable at temperatures of up to at least 350 degrees Celsius.

20. The heat not burn smoking article according to claim 14 , wherein the tubular body is made of cellulose.
