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.

Cartridge for electronic vaping device

An electronic cigarette includes a liquid supply including liquid material, a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol, a wick in communication with the liquid material and in communication with the heater such that the wick delivers the liquid material to the heater, at least one air inlet operable to deliver air to a central air passage upstream of the heater, and a mouth end insert having at least two diverging outlets. The electronic cigarette can also include an air flow diverter which directs incoming air away from a heating zone of the heater.

In one embodiment, the electronic vaping device includes a cartridge and a battery section. The cartridge and the battery section are connectable so as to define an air inlet between a portion of the cartridge and a portion of the battery section.

Electronic vaping device

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.

An electronic smoking article includes a liquid supply including liquid material, a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol, a wick in communication with the liquid material and in communication with the heater such that the wick delivers the liquid material to the heater, at least one air inlet operable to deliver air to a central air passage upstream of the heater, and a mouth end insert having at least two diverging outlets.

A cartridge for an e-vaping device enables simultaneous vaporization of different pre-vapor formulations to form a vapor for vaping by an adult vaper. The cartridge includes a dispensing interface coupled to a plurality of reservoirs and a heater coupled to the dispensing interface in a housing. The dispensing interface may include a trunk and separate roots extending into separate reservoirs, such that the dispensing interface draws different pre-vapor formulations from the reservoirs to the trunk via the separate roots. The heater is coupled to the trunk, such that the heater is operable to simultaneously vaporize the different pre-vapor formulations drawn into the trunk.

Combined cartridge for electronic vaping device

A base for an e-vaping device is configured to couple with multiple cartridges configured to generate separate, respective dispersions. The cartridges may include one or more atomizer assemblies or vaporizer assemblies. The base may include multiple connectors electrically coupled to the power supply. The connectors may be configured to couple multiple dispersion generators to a power supply of the base. The base may include control circuitry configured to independently control dispersion generation by dispersion generators coupled to the base. The control circuitry may independently control dispersion generation by the first and second cartridges based on cartridge information accessed through at least one of the first and second connectors. The control circuitry may control dispersion generation by controlling power supplied to the dispersion generators.

The non-combustible tobacco vaping insert includes a filter having a first diameter, and a tobacco element with a first end contacting the filter, the tobacco element having a second diameter that is smaller than the first diameter of the filter. The cartridge includes a housing, where the cartridge defines an air passage within the housing, and a vaping insert is positioned in at least one first portion of the air passage. The vaping insert is non-combustible and is configured to allow vapor to pass through the vaping insert prior to exiting the cartridge. The vaping insert includes a filter having a first diameter, and a tobacco element with a first end contacting the filter, the tobacco element having a second diameter that is smaller than the first diameter of the filter.

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.

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.

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.

A cartridge of an electronic vaping device includes a flavor carrier. The flavor carrier includes an outer housing extending in a longitudinal direction, an inner housing extending in the longitudinal direction, and a flavor chamber between the outer housing and the inner housing. The outer housing includes at least one outer housing perforation defined in a wall of the outer housing. The inner housing includes at least one inner housing perforation defined in a wall of the inner housing. The flavor chamber is configured to contain a flavoring material.
