Description

Aerosol generating device having a movable housing portion

The present disclosure relates to an aerosol generating device including a first housing portion and a second housing portion movable relative to the first housing portion. The disclosure also relates to an aerosol-generating article comprising a first mouthpiece element at a first end of the aerosol-generating article and a second mouthpiece element at a second end of the aerosol-generating article. The present disclosure also relates to an aerosol-generating article comprising a wrapper and a plurality of spaced apart indicia on an exterior surface of the wrapper.

A number of electrically operated aerosol-generating systems have been proposed in the art in which an aerosol-generating device with an electric heater is used to heat an aerosol-forming substrate, such as a cigarette plug. The aerosol-generating substrate can be provided as part of an aerosol-generating article inserted into the cavity of an aerosol-generating device.

Typically, an aerosol-generating device includes a housing, defining a cavity for receiving an aerosol-generating article. The housing may have a shape that attempts to provide some ergonomic advantage to the user, but typically the size and shape of the housing is driven by the need to accommodate the cavity, electric heater, power supply, and control electronics. Accordingly, known aerosol-generating devices are often sized and shaped to provide only limited ergonomic benefits to the user.

It would be desirable to provide an aerosol-generating device that can provide improved ergonomic benefits to the user.

Aerosol-generating articles typically include an aerosol-forming substrate, such as a cigarette plug, and a mouthpiece downstream of the cigarette plug. Typically, the mouthpiece includes a filter element. These aerosol-generating articles can provide users with limited options for customizing their user experience. Accordingly, some users may attempt to use aerosol-generating articles in ways not intended by the manufacturer. For example, a user may attempt to use an aerosol-generating article without fully inserting the aerosol-generating article into the aerosol-generating device, such that only a portion of the aerosol-forming substrate is heated. However, the result is that some of the aerosol-forming substrate is not heated and is therefore wasted. Additionally, using aerosol-generating articles in this manner can reduce consistency from one user experience to the next. Other users may remove portions of the aerosol-forming substrate by cutting the aerosol-generating article prior to insertion into the aerosol-generating device. This leads to the additional problem of reducing the resistance to suction, which can also adversely affect the user experience.

It would be desirable to provide aerosol-generating articles that can facilitate customization of the user experience.
