Publication number: 20200390150Abstract: The present disclosure relates to aerosol delivery devices and related methods of delivering aerosol to a user. The aerosol delivery devices may include a housing providing multiple aerosol pathways having a mouth-end opening through which aerosol can be inhaled by a user, the housing defining a first aerosol delivery pathway in fluid communication with the mouth-end opening and a second aerosol delivery pathway separate from the first aerosol delivery pathway and in fluid communication with the mouth-end opening. An atomizer including a heating element or piezoelectric element and a liquid transport element in fluid communication with an aerosol precursor composition is provided in fluid communication with the first aerosol delivery pathway. A flavorant-infused material is positioned within the second aerosol delivery pathway and adapted to produce a second aerosol upon contact between the flavorant-infused material and flowing air.Type: ApplicationFiled: August 28, 2020Publication date: December 17, 2020Inventors: Sawyer Hubbard, Eric Taylor Hunt, Karen V. Taluskie, Stephen Benson Sears, Donna Walker Duggins, Michael F. Davis

Publication number: 20170360767Abstract: The invention provides a multi-layered pharmaceutical composition comprising two or more formulations with varying properties. In some embodiments, the pharmaceutical compositions provide combinations of different organoleptic properties within the same product. In certain embodiment, these combinations allow for a modified release profile of active ingredients as the user enjoys the pharmaceutical composition. The invention further provides methods for making and using the pharmaceutical composition.Type: ApplicationFiled: August 31, 2017Publication date: December 21, 2017Inventors: Donna Walker Duggins, John-Paul Mua, Darrell Eugene Holton, Jr., Daniel Verdin Cantrell

Publication number: 20170065000Abstract: An aerosol delivery system is provided, comprising a control body portion including a first elongate tubular member having a power source disposed therein. A cartridge body portion includes a second tubular member having opposed first and second ends. One of the first and second ends is removably engaged with one end of the control body portion. The cartridge body portion further comprises a first aerosol generation arrangement disposed within the second tubular member and configured to operably engage the power source upon engagement between the control body portion and the cartridge body portion. A second aerosol generation arrangement is disposed between the first aerosol generation arrangement and a mouth-engaging end of the aerosol delivery system, the second aerosol generation arrangement being either removably engaged with the cartridge body portion or housed within the second tubular member of the cartridge body portion. An associated method is also provided.Type: ApplicationFiled: November 18, 2016Publication date: March 9, 2017Inventors: Stephen Benson Sears, Karen V. Taluskie, Michael F.

Patent number: 9375033Abstract: A smokeless tobacco gel product is providing, including a tobacco material in an amount of at least about 0.01 weight percent, based on the total weight of the smokeless tobacco gel product; at least about 50 percent by weight of one or more sugar alcohols; a humectant in an amount of at least about 0.1 weight percent; and water in an amount of at least about 10 weight percent. The tobacco material (e.g., particulate tobacco or a tobacco extract such as tobacco-derived nicotine) can be present in an amount of about 0.1 to about 10 weight percent. The humectant amount can be varied to vary the properties of the gel product, with more paste-like consistency achieved with a humectant amount of at least about 7 weight percent, and more syrup-like consistency achieved with a humectant amount of less than about 6 weight percent.Type: GrantFiled: February 14, 2014Date of Patent: June 28, 2016Assignee: R.J.
