Inhaler mouthpiece with flavour element
An inhaler article includes a body extending along a longitudinal axis from a mouthpiece end to a distal end, a mouthpiece air outlet and a distal air inlet, and a capsule cavity within the body and bounded downstream by a mouthpiece. A separator is between the capsule cavity and the mouthpiece including at least one aperture to form an air flow path from the distal air inlet through the capsule cavity, through the mouthpiece to the mouthpiece air outlet. A coating layer of flavour is disposed on an interior surface of the mouthpiece and a protective layer disposed on the coating layer of flavour.
1 . An inhaler article comprising:
a body extending along a longitudinal axis from a mouthpiece end to a distal end;
a mouthpiece air outlet and a distal air inlet;
a capsule cavity within the body and bounded downstream by a mouthpiece;
a separator between the capsule cavity and the mouthpiece comprising at least one aperture to form an air flow path from the distal air inlet through the capsule cavity, through the mouthpiece to the mouthpiece air outlet; and
a coating layer of flavour disposed on an interior surface of the mouthpiece and configured to be in fluid communication with the air flow path and a protective layer disposed on and removably adhered to the coating layer of flavour, wherein the protective layer is configured to be in fluid communication with the air flow path when disposed on the coating layer of flavour and configured to be manually removed from the coating layer of flavour by a user.
2 . The inhaler article of claim 1 , wherein the coating layer of flavour defines at least a portion of a mouthpiece air channel in airflow communication with the capsule cavity.
3 . The inhaler article of claim 1 , wherein the coating layer of flavour is disposed between the protective layer and a mouthpiece inner surface.
4 . The inhaler article of claim 3 , wherein the coating layer of flavour forms a gel layer.
5 . The inhaler article of claim 3 , wherein the protective layer has a thickness in a range from about 20 micrometres to about 60 micrometres.
6 . The inhaler article of claim 1 , wherein the coating layer of flavour forms a gel layer.
7 . The inhaler article of claim 6 , wherein the coating layer of flavour defines an open cylinder.
8 . The inhaler article of claim 1 , wherein the protective layer has a thickness in a range from about 20 micrometres to about 60 micrometres.
9 . The inhaler article of claim 8 , wherein the protective layer comprises foil, paper, polymer, or combinations thereof.
10 . The inhaler article of claim 1 , wherein the coating layer of flavour defines an open cylinder.
11 . The inhaler article of claim 1 , wherein the protective layer adheres to the coating layer of flavour and the protective layer defines a cylinder being coaxial with the body longitudinal axis.
12 . The inhaler article of claim 1 , wherein the protective layer comprises foil, paper, polymer, or combinations thereof.
13 . The inhaler article of claim 1 , further comprising a mouthpiece endcap sealing the mouthpiece air outlet, the mouthpiece endcap is configured to be removable from the mouthpiece end to expose the mouthpiece air outlet.
14 . The inhaler article of claim 13 , further comprising a circumferential line of weakness forming an interface between the mouthpiece endcap and the mouthpiece end.
15 . The inhaler article of claim 13 , wherein the mouthpiece endcap has an outer diameter equal to an outer diameter of the inhaler article body, and the mouthpiece endcap is coaxial with the inhaler article body.
16 . The inhaler article of claim 13 , wherein the protective layer is fixed to the mouthpiece endcap and is configured to be removed from the mouthpiece end with the mouthpiece endcap.
17 . The inhaler article of claim 16 , wherein the protective layer defines a spiral configuration when removed from the mouthpiece end.
18 . The inhaler article of claim 17 , further comprising a circumferential line of weakness forming an interface between the mouthpiece endcap and the mouthpiece end.
19 . The inhaler article of claim 1 , further comprising a capsule disposed within the capsule cavity.
20 . The inhaler article of claim 19 , wherein the capsule contains pharmaceutically active particles comprising nicotine, the pharmaceutically active particles having a mass median aerodynamic diameter in a range from about 0.5 micrometres to about 4 micrometres.
