Abstract: A package that may be employed to store a tobacco-containing material is provided. The package may include a container and a valve assembly. The container may include a body portion and a cover configured to engage the body portion. The body portion may define an internal space therein. The valve assembly may be configured to affect an atmosphere within the internal space of the container. For example, the valve assembly may remain closed except when releasing pressure from the internal space. Thereby, by way of further example, the valve assembly may vent the container so as to avoid damage thereto, while reducing moisture loss from the tobacco-containing material stored in the internal space.

Abstract: The present disclosure relates to an aerosol delivery device that includes a reservoir housing that defines a mouthpiece channel. The aerosol delivery device includes a sealing member configured to be received within the reservoir housing to define a reservoir chamber configured to retain an aerosol precursor composition therein. The aerosol delivery device also includes a substrate member that is configured to be received within the reservoir housing and to be directly engaged with a vaporizing assembly for forming an aerosol. The reservoir housing, sealing member, substrate member, and/or vaporizing assembly can be used for forming aerosols with precise and reproducible compositions.

Abstract: The invention provides an smokeless tobacco composition adapted for oral use, the composition including a tobacco material and an effervescent material. The effervescent material includes an acid component and a base component, wherein the acid component includes a triprotic acid such as citric acid and at least one additional acid. The invention also provides a method for making a smokeless tobacco composition that involves first forming a granulation mixture, granulating the granulation mixture, and then blending the resulting granules with further blending components. Thereafter, the material can be formed into a predetermined shape, such as by compression or extrusion. The acid component of the effervescent material is divided into two portions, the first portion added to the granulation mixture and the remaining portion added during the blending step.

Abstract: A pouched product adapted for release of a water-soluble component therefrom is provided herein. The pouched product can include an outer water-permeable pouch defining a cavity containing a composition that includes a water-soluble component capable of being released through the water-permeable pouch and has a surface area, wherein the outer water-permeable pouch can include a nonwoven web including a plurality of heat sealable binder fibers blended with a second plurality of dissimilar fibers. The nonwoven web can be carded, hydroentangled and point bonded.

Abstract: The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides a heating member that can be formed of a heating element conformed to a heater substrate configured as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size. In some embodiments, the disclosure provides methods of forming an aerosol delivery device, which can include providing a shell, providing a heating member formed of a heating element conformed to a substrate, configuring the heating member as a truncated cone (or similar shape) having a first end of a first size and a second end of greater size, and inserting the heating member within the shell.

Abstract: A pouched product configured for insertion into the mouth of a user of that product is provided herein. The pouched product can include an outer water-permeable pouch defining a cavity containing a composition adapted for oral use and having a surface area, wherein the outer water-permeable pouch can include a nonwoven web including a first plurality of continuous filament heat sealable binder fibers oriented substantially parallel to each other in a first direction, a second plurality of continuous filament heat sealable binder fibers oriented substantially parallel to each other in a second direction, wherein the first direction and the second direction are substantially perpendicular to each other, and wherein the first plurality of continuous filament heat sealable binder fibers and the second plurality if continuous filament heat sealable binder fibers are bonded with a heated lamination process.

Abstract: The invention provides a smokeless tobacco composition adapted for oral use, the composition including a tobacco material and an effervescent material. The effervescent material includes a sugar material containing an entrapped gaseous component, such that release of the entrapped gaseous component occurs upon dissolution of the sugar material in the oral cavity. The invention also provides a method for making a smokeless tobacco composition that involves mixing a tobacco material with an effervescent material, the mixing step including either admixing a granulated composition comprising a tobacco material with a gasified sugar material in particulate form, or forming a gasified sugar material in situ by mixing a water source with a molten composition comprising a tobacco material and a sugar alcohol.

Abstract: The invention provides a tobacco product including a flavorful tobacco composition in the form of an extract of a fire-cured tobacco material. Exemplary tobacco products include smoking articles, smokeless tobacco compositions, and aerosol-generating devices that do not burn tobacco. The invention also provides a process for preparing a smokeless tobacco composition, the method including: mixing a fire-cured tobacco material having a first benzo[a]pyrene concentration with water to produce an aqueous slurry; maintaining the slurry for a time and at a temperature sufficient to form a fire-cured tobacco extract, the aqueous fire-cured tobacco extract exhibiting a second benzo[a]pyrene concentration lower than the first benzo[a]pyrene concentration; separating the aqueous fire-cured tobacco extract from a residual pulp material, and mixing the aqueous fire-cured tobacco extract with a tobacco or non-tobacco plant material to form a smokeless tobacco composition.
