Smoking article comprising extinguisher element

A smoking article comprising a tobacco rod and a mouthpiece secured to a downstream end of the tobacco rod, the mouthpiece comprising:

• a tubular element defining a longitudinal channel, wherein the tubular element is provided adjacent the downstream end of the tobacco rod;
• a downstream segment of filter material, wherein the downstream segment of filter material is downstream of the tubular element and spaced apart from the tubular element to define a cavity between the tubular element and the downstream segment of filter material;
• and
• an extinguisher element comprising:
• a compressible reservoir provided in the cavity between the tubular element and the downstream segment of filter material, the compressible reservoir containing a liquid;
• a neck portion extending in a longitudinal direction upstream from the reservoir and having an open end, wherein the neck portion is received in the longitudinal channel of the tubular element such that the open end is proximate the downstream end of the tobacco rod;
• and
• a seal provided over the open end of the neck portion, wherein upon compression of the reservoir during use, the seal is broken and the liquid from the reservoir is releasable through the neck portion directly into the tobacco rod,
• wherein the compressible reservoir has an outer diameter which is substantially the same as an outer diameter of the downstream segment of filter material.

A method of manufacturing a mouthpiece for a smoking article, the method comprising the steps of:

• providing a tubular element having a longitudinal channel;
• providing an extinguishing element comprising a compressible reservoir;
• a neck portion extending from the reservoir and having an open end;
• and a seal provided over the open end of the neck portion;
• inserting the neck portion of the extinguishing element into the longitudinal channel of the tubular element;
• combining the tubular element and the extinguishing element with a segment of filter material such that the reservoir of the extinguishing element is positioned between the tubular element and the segment of filter material and such that a compressible reservoir outer diameter is substantially the same as a filter material downstream segment outer diameter;
• and
• circumscribing the tubular element, the extinguishing element and the segment of filter material with a wrapper to form the mouthpiece.
