Filtered single dose smoking device

Abstract

A filtered, tubular smoking device having an externally accessible single dose bowl at one end and a mouthpiece at an opposing end. A longitudinal bore connects the bowl to the mouthpiece to enable smoke generated from the combustion of smoking material in the bowl to be inhaled. The tubular member is made up of a mouthpiece portion removeably engaged to a shank portion. The mouthpiece portion is provided with a chamber coaxial with the longitudinal bore and having an increased diameter over that of the bore in order to sealingly receive a filter therein. The filter is compressed longitudinally and thereby expanded radially to ensure a sealed engagement in the chamber. However, the filter may removed, discarded and replaced by disengaging the mouthpiece portion from the shank portion in order to gain access to the filter chamber.
