Abstract
Flavor delivery articles employ an electrical resistance heating element and an electrical power source to provide a flavored aerosol. The articles advantageously comprise a disposable portion and a reusable controller. The disposable portion normally includes a flavor substance and an air permeable resistance heating element having a surface area greater than 1 m.sup.2 /g, which usually carries an aerosol forming substance. The reusable controller normally includes a puff-actuated current actuation means, a time-based current regulating means to control the temperature of the heating element, and a battery power supply.
Claims136
A disposable portion of a flavor delivery article containing a flavor substance for use with a source of electrical power comprising:
- (a) an electrical resistance heating element having a surface area greater than 1 m.sup.2 /g;
- and
- (b) aerosol forming substance carried by the heating element prior to use.
A disposable portion of a flavor delivery article containing a flavor substance for use with a source of electrical power comprising:
- (a) an air passageway at least partially through the disposable portion;
- (b) an air permeable electrical heating element located in the air passageway;
- and
- (c) an aerosol forming substance.
A flavor delivery article containing a flavor substance or use with a source of electrical power comprising:
- (a) an electrical resistance heating element having a surface area greater than 1 m.sup.2 /g;
- (b) aerosol forming substance carried by the heating element prior to use;
- and
- (c) puff actuated control means for permitting current flow through the heating element during draw by the user.
A flavor delivery article containing a flavor substance for use with a source of electrical power comprising:
- (a) an electrical resistance heating element;
- (b) aerosol forming substance;
- (c) switch means for actuating and deactuating current flow through the heating element;
- and
- (d) time based means for (i) permitting unrestricted current flow through the heating element for an initial predetermined time period upon current actuation, and (ii) for subsequently regulating current flow until current deactuation.
A flavor delivery article containing a flavor substance for use with a source of electrical power comprising:
- (a) an air passageway at least partially through the article;
- (b) an air permeable electrical resistance heating element located in the air passageway;
- (c) an aerosol forming substance;
- (d) puff actuated control means for permitting current flow through the heating element during draw by the user;
- and
- (e) a mouth end.
