Abstract
A cigarette is provided including a reusable, air-permeable shell having a cavity and smokable material for being positioned in the cavity and smoked in the shell. The shell conceals and retains the smokable material before, during, and after smoking. A method of making a cigarette is also described.
Claims18
A device, for use in smoking a rod of smokable material, comprising:
- an air permeable shell adapted to conceal and retain the rod of smokable material before, during, and after smoking;
- the shell being reusable to conceal and retain a subsequent rod of smokable material after a preceding rod of smokable material has been smoked, the shell having a permeability of greater than 5 Coresta units;
- an air permeable cap attachable to at least one end of the shell;
- an air permeable wrapper around the shell;
- and
- wherein the wrapper material is paper.

A device for use in smoking a rod of smokable material, comprising:
- an air permeable shell adapted to conceal and retain the rod of smokable material before, during, and after smoking;
- the shell being reusable to conceal and retain a subsequent rod of smokable material after a preceding rod of smokable material has been smoked, the shell having a permeability of greater than 5 Coresta units;
- an air permeable cap attachable to at least one end of the shell;
- an air permeable wrapper around the shell;
- and wherein the wrapper material is sufficiently sensitive to heat that the wrapper material discolors as a result of heat generated by a burning rod of smokable material concealed in the shell and provides an indication of what portion of the rod of smokable material has been smoked.

A device for use in smoking a rod of smokable material, comprising:
- an air-permeable shell adapted to conceal and retain a rod of smokable material before, during, and after smoking, the shell being reusable to conceal and retain a subsequent rod of smokable material after a preceding rod of smokable material has been smoked, the shell having a permeability of greater than 5 Coresta units;
- and
- an air permeable cap attachable to at least one end of the shell;
- and
- one or more pieces of material disposed sufficiently proximate an exterior surface of the shell that the pieces of material act as heat sinks to reduce a burn rate of a burning rod of smokable material.
