  • THP Tobacco Heated Product
  • Smoking articles such as cigarettes, cigars and the like burn tobacco during use to create tobacco smoke. Attempts have been made to provide alternatives to these articles that burn tobacco by creating products that release compounds without burning. Examples of such products are heating devices which release compounds by heating, but not burning, the material.
  • the material may be for example tobacco or other non-tobacco products, which may or may not contain nicotine.
  • These heating devices may include a housing which holds internal components is held by the user.
  • An aerosol generating device may be provided with a housing which contains some or all of the components for generating an aerosol from a received consumable. Parts of the device housing are held by the user while the device is carried, or when it is used to generate an aerosol. The particular form of the housing can therefore affect or improve the usability of the device.
  • the housing of the device is used to accommodate the components and functionality which generate the aerosol, and isolate some components internally from the user.
  • the shape and size of the housing can therefore also be influenced by the underlying functionality of the device.
  • a device which generates aerosol by heating of a tobacco product in a heat-not-burn arrangement could be provided with a housing which accommodates a power source, a circuit and a form of heating zone.
  • a THP device there may be a large number of components to be accommodated and isolated from the user.
  • the usability of the device can be improved by providing the housing with a shape which generally conforms to being gripped by a user’s hand.
  • the housing may be provided with surfaces which are flat or given a certain curvature so as to be easily held or gripped in a hand.
  • the form of the housing may therefore be influenced by both the usability of the device and the accommodation of the aerosol generating functionality.
  • particular housing forms and shapes can be particularly desirable or advantageous to one or more particular types of aerosol generator.
  • a combination of planar and convex outer surfaces may be particularly easy to grip during use of the device, while providing space for accommodating particular components.

  • the tactile feedback can, in particular, be affected by a surface texture of parts of the housing.
  • a surface which has a texture with a relatively high roughness can impart the feeling of an device which is easy to grip, and can provide a reassuring tactile feedback.

  • One removable housing component may comprise a side panel with a generally curved, convex shape, which conforms to the user grip.
  • This section of the housing may be particularly influential on the overall user impression, because the convex outer surfaces are those most commonly held or gripped by the user during use of the device.

It is also desirable to provide a removable housing component and device housing which may be easily manufactured at a large scale. It is therefore a benefit to be able to control a gap which might be formed between removable component and underlying housing, to account for manufacturing tolerances.
