Abstract

A self-extinguishing pipe is described for use with tobacco or other smoking material. The pipe is made in two parts, a body and an endpiece, and holds a filter internally. The endpiece includes a reservoir for the tobacco or other smoking material at one end which has an adjustable base for changing the depth of the reservoir. The two-part construction and adjustable base facilitate cleaning of the pipe, replacement of the filter, and removal of ash without needing additional tools. The depth of the reservoir is adjusted by rotating an inner component of the endpiece in relation to a surrounding cowl. Various bores through the body of the pipe and the components of the endpiece communicate with each other so as to form an air passage from the smoking material to the mouth end of the pipe, thereby allowing smoke to be drawn into the user's mouth.

Claims22

Dependent claims

A pipe for use with smoking materials, the pipe comprising:

an elongated body having a longitudinal axis and opposite ends, the ends having openings therein, the body having an interior wall defining a passage extending through the body and communicating with the openings at the ends;
an endpiece removably secured to one of the ends of the body, the endpiece having portions defining a reservoir for smoking materials, the reservoir in communication with the passage in the body when the endpiece is secured to the body;
the reservoir comprising a base and a side extending from the base and terminating in an edge and having a depth measurable from the edge of the reservoir;
and
means for varying the volume of the reservoir between a maximum volume and a minimum volume by rotating the body relative to the endpiece about the longitudinal axis, whereby the means for varving the volume advances the base toward the edge to decrease the depth of the reservoir when the body is rotated relative to the endpiece in a first direction and retracts the base away from the edge to increase the depth of the reservoir when the body is rotated relative to the endpiece in a second direction.
