Abstract: A wrapper of a smoking article comprising a base web and banded regions comprising a leading edge, a trailing edge and a plurality of add-on material-free openings between said leading edge and said trailing edge. The add-on material-free openings establish a predetermined, nominal opened-area within said banded regions to control diffusivity. The add-on material can be applied by a gravure roller comprising a surface region with cells, cell-free areas and a chevron shape.

Abstract: An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.

At least one first heater is operable upon at least one portion of the at least one first wick to at least partially volatilize the pre-vapor formulation and form a vapor. A support plate is operable to support the at least one first heater and at least partially support the at least one first wick, the support plate being operable to form an electrical connection between the at least one first heater and a power supply.

Abstract: A cartridge for an e-vaping device includes a reservoir configured to hold a pre-vapor formulation and a channel structure that includes a channel surface with one or more open-microchannels. An open-microchannel in the channel structure may be in fluid communication with the reservoir and may transport pre-vapor formulation from the reservoir to a heating element based on capillary action of the pre-vapor formulation through the open-microchannels. The heating element may vaporize the pre-vapor formulation drawn through one or more open-microchannels. The cartridge may be independent of fibrous dispensing interfaces, including one or more wicks. Fabrication of such a cartridge may be simplified, faster, cheaper, some combination thereof, or the like relative to fabrication of a cartridge that includes a fibrous or soft dispensing interface to draw pre-vapor formulation from a reservoir to a heating element.

Abstract: A cartridge for an e-vaping device enables separate vapors to be formed proximate to separate, respective ends of the cartridge. The cartridge includes multiple reservoirs and separate vaporizer assemblies coupled to separate reservoirs on opposite ends of the reservoirs. The separate reservoirs may hold separate pre-vapor formulations. The separate vaporizer assemblies may draw separate pre-vapor formulations from separate reservoirs towards opposite ends of the cartridge and vaporize the separate pre-vapor formulations via operation of separate heaters proximate to the separate ends. The separate heaters may be independently controlled to independently control vapor formation at the separate ends. The heaters may be controlled to independently control vapor formation rates proximate to the separate ends. The heaters may be controlled to form separate vapors at least one of simultaneously, concurrently, and at different times.

Abstract: A vaporizer assembly for an e-vaping device includes a heater coil structure, a set of electrical lead structures coupled to opposite ends of the heater coil structure, and a non-conductive connector structure connected to each of the electrical lead structures, such that the electrical lead structures are coupled together independently of the heater coil structure. The vaporizer assembly may contact a dispensing interface structure through the heater coil structure. The vaporizer assembly may heat pre-vapor formulation drawn from a reservoir by the dispensing interface. The heater coil structure may define a surface, and the vaporizer assembly may apply a mechanical force to the dispensing interface structure, such that the heater coil structure is in compression with the dispensing interface structure and the heater coil structure surface is substantially flush with a surface of the dispensing interface structure. The heater coil structure may define a three-dimensional surface.
