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.

First claim

The invention claimed is:

1. 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.

2. A stack of caps, comprising;
a plurality of caps according to claim 1 ,
wherein said each cap is placed one inside another.

3. An extinguisher cap dispenser, comprising:
a housing portion defining a compartment configured to receive a plurality of caps and comprising a compartment opening configured to receive a combustion zone of a smoking article into the compartment; and
a lid portion moveable between an open position and a closed position and being configured to open and to close the compartment opening,
wherein the compartment contains at least one cap according to claim 1 .

4. The extinguisher cap dispenser according to claim 3 ,
wherein the compartment is sized to accommodate a single stack of caps
arranged such that only a cap of the single stack that is nearest the compartment opening is accessible by a user, and
wherein said each cap is placed one inside another.

5. The extinguisher cap dispenser according to claim 3 ,
wherein the compartment contains a stack of the caps
wherein said each cap is placed one inside another.

6. A pack of smoking articles, comprising:
a container containing at least one smoking article; and
a stack of a plurality of caps according to claim 1 ,
wherein said each cap is placed one inside another.

7. The cap according to claim 1 , wherein the heat reactive material comprises an intumescent material.

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

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

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

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

12. The cap according to claim 1 , wherein an end of the cap body opposite the opening is closed.
