Abstract

The present invention describes articles, such as smoking articles, that can provide an inhalable substance in a form suitable for inhalation by a consumer. The article comprises a cartridge with an inhalable substance medium therein, control housing that includes an electrical energy source and an electrical power source, and a heating member that may be located in either the cartridge or the control housing. The control housing further may include puff-actuated current actuation components and current regulation components.

Claims

1. A reusable control unit for use with a disposable smoking article, the reusable control unit comprising a control housing including:

a receiving end for receiving an engaging end of the disposable smoking article and having an electrical energy source that includes a projection extending outwardly therefrom and that includes a component that forms an electrical connection with electrical contacts on a separate electrical heating member; and

a control unit section that houses a power source, a switching component that actuates flow of electrical current from the electrical energy source to the electrical heating member, and a flow regulating component that regulates a previously initiated current flow from the electrical energy source to the electrical heating member, wherein the component that forms an electrical connection with the electrical contacts is located on the projection.

2. The reusable control unit of claim 1, wherein the power source includes a battery.

3. The reusable control unit of claim 1, wherein the electrical energy source includes a capacitor.

4. The reusable control unit of claim 1, wherein the switching component comprises a puff-actuated switch.

5. The reusable control unit of claim 1, wherein the switching component comprises a pushbutton.
