An Aerosol Generating Device

Abstract

An aerosol generating device includes a main body configured to receive an aerosol generating article. The main body includes an outer casing, an inner casing (20), and an inner cover. The inner cover is secured to a periphery of the inner casing to define a space between the inner surface of the inner cover and an inner surface of the inner casing. The aerosol generating device further includes an outer cover positioned over the inner cover and having an inner surface and an outer surface. The outer surface of the outer casing and the outer surface of the outer cover define an external surface of the aerosol generating device, and a periphery of the outer cover contacts a periphery of the outer casing so that the outer surface of the outer cover lies substantially flush with the outer surface of the outer casing to define a continuous external surface.

1 . An aerosol generating device comprising a main body configured to receive an aerosol generating article, the main body comprising:
 an outer casing having an inner surface and an outer surface;   an inner casing positioned inside the outer casing adjacent to the inner surface;   an inner cover having an inner surface and an outer surface, the inner cover being secured to a periphery of the inner casing to define a space between the inner surface of the inner cover and an inner surface of the inner casing;   an outer cover having an inner surface and an outer surface, the outer cover being positioned over the inner cover;   wherein the outer surface of the outer casing and the outer surface of the outer cover define an external surface of the aerosol generating device, and a periphery of the outer cover contacts a periphery of the outer casing so that the outer surface of the outer cover lies substantially flush with the outer surface of the outer casing to define a continuous external surface.   
     
     
         2 . The aerosol generating device according to  claim 1 , wherein the aerosol generating device has a proximal end, a distal end, and a longitudinal direction extending between the proximal end and the distal end, and wherein the periphery of the outer cover is curved in a transverse direction relative to the longitudinal direction between a front and a rear of the aerosol generating device and the periphery of the outer casing is also curved in said transverse direction so that the flush outer surfaces of the outer cover and the outer casing define a curved continuous external surface in said transverse direction. 
     
     
         3 . The aerosol generating device according to  claim 1 , wherein:
 the main body includes a peripherally extending groove;   the outer cover includes a peripherally extending rim and a peripherally extending collar positioned inwardly with respect to the peripherally extending rim; and   the peripherally extending collar is positioned in the peripherally extending groove and the peripherally extending rim contacts the periphery of the outer casing.   
     
     
         4 . The aerosol generating device according to  claim 3 , wherein the peripherally extending collar is spaced inwardly from the periphery of the outer casing. 
     
     
         5 . The aerosol generating device according to  claim 3 , wherein the periphery of the outer casing includes a peripherally extending ledge and the peripherally extending rim of the outer cover contacts the peripherally extending ledge of the outer casing. 
     
     
         6 . The aerosol generating device according to  claim 3 , wherein the peripherally extending groove has a depth which is greater than a depth of the peripherally extending collar. 
     
     
         7 . The aerosol generating device according to  claim 3 , wherein the peripherally extending groove is defined between a peripheral portion of the inner cover and a peripheral portion of the outer casing. 
     
     
         8 . The aerosol generating device according to  claim 1 , further comprising at least one attachment element for releasably attaching the outer cover to the inner cover. 
     
     
         9 . The aerosol generating device according to  claim 8 , wherein the attachment element comprises a magnet. 
     
     
         10 . The aerosol generating device according to  claim 1 , further comprising a snap-fit connection structure for securing the inner cover to the inner casing. 
     
     
         11 . The aerosol generating device according to  claim 1 , wherein the outer casing comprises a metal. 
     
     
         12 . The aerosol generating device according to  claim 1 , wherein the outer cover comprises a plastics material. 
     
     
         13 . The aerosol generating device according to  claim 1 , wherein the aerosol generating device comprises an aerosol generating unit in the space defined between the inner surface of the inner cover and the inner surface of the inner casing, the aerosol generating unit including a cavity for receiving an aerosol generating article. 
     
     
         14 . The aerosol generating device of  claim 11 , wherein the metal comprises aluminium.
