An aerosol generating article (10; 110) comprising: an aerosol generating substrate; a mouthpiece in axial alignment with the aerosol generating substrate; a tipping wrapper (20; 120) wrapped around the mouthpiece and at least a portion of the aerosol generating substrate, the tipping wrapper comprising: a first weakening line extending circumferentially around at least a portion of the tipping wrapper (20; 120); a removable tipping wrapper portion (26; 126) extending downstream from the at least one weakening line; an upstream tipping wrapper portion extending upstream from the first weakening line, wherein the upstream tipping wrapper portion is attached to a downstream portion of the aerosol generating substrate and an upstream portion of the mouthpiece; and a longitudinal edge (28; 128) extending along the outer surface of the mouthpiece, the longitudinal edge (28; 128) comprising a tipping wrapper projection (32; 132) downstream of the first weakening line on the removable tipping wrapper portion (26; 126) and a first straight line portion (30; 130) extending upstream from the tipping wrapper projection (32; 132), wherein the tipping wrapper projection (32; 132) comprises a first curved transition portion (38; 138) connecting the first straight line portion (30; 130) of the longitudinal edge (28; 128) to the remainder of the tipping wrapper projection (32; 132) and wherein the first curved transition portion (38; 138) follows a convex curve. an aerosol generating substrate; a mouthpiece in axial alignment with the aerosol generating substrate; a tipping wrapper (20; 120) wrapped around the mouthpiece and at least a portion of the aerosol generating substrate, the tipping wrapper comprising: a first weakening line extending circumferentially around at least a portion of the tipping wrapper (20; 120); a removable tipping wrapper portion (26; 126) extending downstream from the at least one weakening line; an upstream tipping wrapper portion extending upstream from the first weakening line, wherein the upstream tipping wrapper portion is attached to a downstream portion of the aerosol generating substrate and an upstream portion of the mouthpiece; and a longitudinal edge (28; 128) extending along the outer surface of the mouthpiece, the longitudinal edge (28; 128) comprising a tipping wrapper projection (32; 132) downstream of the first weakening line on the removable tipping wrapper portion (26; 126) and a first straight line portion (30; 130) extending upstream from the tipping wrapper projection (32; 132), wherein the tipping wrapper projection (32; 132) comprises a first curved transition portion (38; 138) connecting the first straight line portion (30; 130) of the longitudinal edge (28; 128) to the remainder of the tipping wrapper projection (32; 132) and wherein the first curved transition portion (38; 138) follows a convex curve. a first weakening line extending circumferentially around at least a portion of the tipping wrapper (20; 120); a removable tipping wrapper portion (26; 126) extending downstream from the at least one weakening line; an upstream tipping wrapper portion extending upstream from the first weakening line, wherein the upstream tipping wrapper portion is attached to a downstream portion of the aerosol generating substrate and an upstream portion of the mouthpiece; and a longitudinal edge (28; 128) extending along the outer surface of the mouthpiece, the longitudinal edge (28; 128) comprising a tipping wrapper projection (32; 132) downstream of the first weakening line on the removable tipping wrapper portion (26; 126) and a first straight line portion (30; 130) extending upstream from the tipping wrapper projection (32; 132), wherein the tipping wrapper projection (32; 132) comprises a first curved transition portion (38; 138) connecting the first straight line portion (30; 130) of the longitudinal edge (28; 128) to the remainder of the tipping wrapper projection (32; 132) and wherein the first curved transition portion (38; 138) follows a convex curve.
