Abstract

The present invention relates to a smoking article which has the appearance of a conventional pipe. The pipe of the present invention is capable of producing substantial quantities of aerosol, preferably without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products.

These and other advantages are obtained by providing a pipe which includes a disposable cartridge containing a short, i.e., less than about 30 mm long, preferably carbonaceous, fuel element, a physically separate aerosol generating means including an aerosol forming substance, and means for retaining the cartridge within the pipe bowl.

Claims

1. A pipe having a bowl comprising:

(a) a replaceable cartridge, which cartridge comprises;

(i) a fuel element less than about 30 mm in length; and

(ii) a physically separate aerosol generating means in a conductive heat exchange relationship with the fuel element, the aerosol generating means including at least one aerosol forming material; and

(b) means for retaining the cartridge in the bowl of the pipe, the retaining means being adapted to permit removal and replacement of the cartridge.

2. The pipe of claim 1, further comprising means for ejecting the cartridge from the bowl of the pipe.

3. The pipe of claim 1, wherein the retaining means comprises a removable member having a passageway in communication with the passageway of the stem of the pipe, the passageway in the removable member being adapted to receive the removable cartridge.

4. The pipe of claim 1, wherein the cartridge comprises a conductive container which encloses at least a portion of the aerosol generating means.

5. The pipe of claim 1, wherein the cartridge does not extend above the rim of the pipe bowl.
