## Abstract

A cap for extinguishing a smoking article is provided, including a hollow cap body having an opening configured to receive a combustion zone of a smoking article, the cap body including an intumescent heat reactive material configured to deform in response to heat from the combustion zone such that at least part of the cap body fits tightly against the smoking article to substantially prevent a supply of air to the combustion zone.

## Claims

A cap for extinguishing a smoking article, the cap comprising:
a hollow cap body having an opening configured to receive a combustion zone of a smoking article, the cap body comprising a heat reactive material configured to deform in response to heat from the combustion zone such that at least part of the cap body fits tightly against the smoking article to substantially prevent a supply of air to the combustion zone, wherein the cap body tapers outwardly towards the opening such that a stack of such caps can be formed by placing one inside another: and
a non-stick layer disposed on an exterior of the cap body and configured to facilitate removal of the cap from the stack of the caps.

### Claim 8 (depends on 1)

The cap according to claim 1, wherein the heat reactive material is a heat reactive coating on an interior surface of the cap body.

### Claim 9 (depends on 1)

The cap according to claim 1, wherein the heat reactive material comprises a heat shrink material.

### Claim 10 (depends on 1)

The cap according to claim 1, wherein the cap body further comprises a heat insulating material disposed outwardly from the heat reactive material.

### Claim 11 (depends on 1)

The cap according to claim 1, wherein the cap body is cup shaped.
