International Classification:

A24F 302
A24F 904
A24F 912

US Classification:

131244

Abstract:

A cleaning unit used to clean condensates formed during use of a component of a smoking system. The component can be a heating fixture having a cigarette receiving section and a plurality of longitudinally extending circumferentially spaced apart heating elements located within a can which accumulates the condensates. During a cleaning operation, the heating fixture is fitted within a cavity in the cleaning unit such that the cigarette receiving end of the heating fixture engages an O-ring and the terminal base portion abuts against an indented stop in an interior sidewall of a removable portion of the housing. The cleaning unit includes a water inlet connected to a source of pressurized water such as a faucet and a spray member extends into the cigarette receiving section to spray jets of water against the interior of the can. The housing can include a main flow passage which supplies pressurized water to the spray member and one or more bypass passages whereby water used to clean the heating fixture can exit the housing through one outlet and water which bypasses the heating fixture can exit the housing through other outlets. The housing can include a pulsating mechanism to pulsate jets of pressurized water against the interior of the heating fixture.

Assignee:

Philip Morris Incorporated - New York NY

International Classification:

A24B 1500

US Classification:

131359

Abstract:

This invention relates to a heat source comprising metal carbide and a method for preparing the same using a reducing/carbidizing atmosphere. The metal carbide heat sources of this invention have ignition temperatures that are substantially lower than conventional carbon particles normally used in carbonaceous heat sources, while at the same time provide sufficient heat to release a flavored aerosol from a flavor bed for inhalation by the smoker. Upon combustion, the heat sources produce substantially no carbon monoxide.

International Classification:

A24B 1500

US Classification:

131359

Abstract:

A chemical heat source comprising metal nitride, metal oxide and carbon, particularly useful in smoking articles, and methods of making the heat source are provided. The metal nitride of the heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time provides sufficient heat to release a flavored aerosol from a flavor bed for inhalation by the smoker. Upon combustion the heat source produces virtually no carbon monoxide. The metal nitride is prepared by pre-forming the starting materials into a desired shape, and converting them to metal nitride in situ, without substantially altering the shape of the starting materials.

International Classification:

A24F 4700

US Classification:

131329

Abstract:

Methods and apparatuses for cleaning an electrical lighter are provided. A sleeve, e. g. , ceramic or metal, surrounds the heater fixture, and a resistive heating element is in thermal proximity with the sleeve. The resistive heating element is either a dedicated element or the cigarette heating elements. The sleeve serves as a aerosol barrier and condensate accumulator to protect other components. Periodically, e. g. , substantially contemporaneously with a battery recharge, the heating element is activated to thermally liberate condensates deposited on the sleeve during smoking and also heats, and thereby cleans, other components. Also, a cleaning element is optionally inserted into the cigarette receptacle of the electrical lighter or placed at the exit thereof to absorb, attract and/or catalytically break down the thermally liberated condensates. The sleeve also directs a desired flow path for drawn air within an electrical lighter toward the cigarette.
