The present disclosure relates to reservoirs for storing products in electronic smoking articles. The reservoir is manufactured from cellulose acetate fiber, thermoplastic fiber, non-thermoplastic fiber, or a combination thereof. The reservoir is substantially tubular in shape and is adapted to accommodate internal components of the smoking article thereby increasing reservoir capacity. The internal components particularly can comprise an atomizer, which may include a braided wick.

Electronic smoking article with improved storage and transport of aerosol precursor compositions

The present disclosure relates to an electronic smoking article that provides for improved aerosol delivery. Particularly, the article provides for separate delivery of two or more components of an aerosol precursor composition to one or more heaters so as to control the rate of delivery or the rate of heating of the separate components of the aerosol precursor composition.

Reservoir and heater system for controllable delivery of multiple aerosolizable materials in an electronic smoking article

The present disclosure relates to a cartridge for an aerosol delivery device such as a smoking article. The cartridge may include a base, a reservoir substrate, and an atomizer. The reservoir substrate may define a cavity therethrough. The atomizer may comprise a liquid transport element and a heating element extending at least partially about the liquid transport element. The atomizer may extend through the cavity through the reservoir substrate such that the heating element is positioned proximate an end of the reservoir substrate. Ends of the liquid transport element may extend to an opposing end of the reservoir substrate. A related method for assembling a cartridge for a smoking article is also provided.

Aerosol delivery device

The present disclosure relates to electronic smoking articles exhibiting improved moisture control of a reservoir contained therein. The reservoir can be formed of fibrous materials, such as cellulose acetate fiber, thermoplastic fiber, non-thermoplastic fiber, or a combination thereof. The disclosure further provides methods for forming electronic smoking articles and methods of packaging electronic smoking articles (including cartridges thereof) so as to improve moisture control of the reservoir.

Electronic smoking article with improved storage of aerosol precursor compositions

The present disclosure relates to atomizers for an aerosol delivery device such as a smoking article. The atomizer may include a liquid transport element and a wire extending along at least a portion of a longitudinal length thereof. The wire may define contact portions configured to engage heater terminals and a heating portion configured to produce heat. The heating portion may include a variable coil spacing. In other atomizers, the wire may extend at least partially through the liquid transport element proximate the contact portions. Related inputs, cartridges, aerosol production assemblies, and methods of forming atomizers are also provided.

Atomizer for an aerosol delivery device and related input, aerosol production assembly, cartridge, and method

The present disclosure relates to an aerosol delivery device. The aerosol delivery device may include a control body and a cartridge. The cartridge may include a base, a flow director, an outer body, a reservoir substrate, an outer body, and a mouthpiece. Heating elements may be molded into the flow director. The flow director may be welded to the base and the outer body, or the base and the flow director may include deformable ribs that engage the outer body. The flow director and the outer body may cooperatively define a reservoir compartment in which the reservoir substrate and the atomizer are received. The flow director and the base may define an electronics compartment in which an electronic control component is received. A related assembly method is also provided.

Sealed cartridge for an aerosol delivery device and related assembly method

Methods for producing dissolving grade pulp and microcrystalline cellulose from tobacco are provided. The methods include chemical pulping a tobacco input to form a tobacco pulp. Chemical pulping the tobacco input includes combining the tobacco input with a strong base defining a weight from about 5% to about 50% of the tobacco input, and heating the tobacco input and the strong base with an H-factor from about 500 to about 3,300. Further, the methods include bleaching the tobacco pulp to produce a dissolving grade pulp. Bleaching the tobacco pulp may include chlorination of the tobacco pulp with a chlorine dioxide solution, and caustic extraction of the tobacco pulp with a second strong base. A related tobacco-derived microcrystalline cellulose product is also provided, which can be used as a binder, a filler, and/or a texturizer in a tobacco product, such as a smokeless tobacco product.

Method for producing microcrystalline cellulose from tobacco and related tobacco product

The present disclosure relates to atomizers for an aerosol delivery device such as a smoking article. The atomizer may include a liquid transport element and a wire continuously extending along a longitudinal length thereof. The wire may define end portions, contact portions, and a heating portion. The wire may be continuously wound about the liquid transport element such that each of the portions of the wire defines coils. A related input, cartridge, and method of forming atomizers also provided.
