Cool pipe with self ignition means

Abstract

A pipe including self-contained means for igniting the tobacco has an outer bowl and an inner sub-bowl placed in the outer bowl. The sub-bowl is of smaller size than the outer bowl to define a smoke cavity between the outside wall of the sub-bowl and the inside wall of the outer bowl. The sub-bowl includes a plurality of holes adjacent its top above the tobacco level to enable the smoke generated in the tobacco to be drawn through the holes into the smoke cavity and through the pipe stem, outwardly extending from the outside bowl in a conventional manner. A third container including a heating element energizeable from an external power source is located at the base of the sub-bowl to receive and ignite the tobacco. An air vent tube is provided in one embodiment, extending through the wall of the outer bowl to the smoke cavity to cut the density of the smoke produced, The vent can be closed by the user's finger, as desired. Also, a light is provided in the wall of the outer bowl to indicate the energization of the heating element. The thermal insulation properties of the sub-bowl enable the pipe to be easily handled and to develop a cool smoke.
