An Easy to Fill and Easy to Assemble Aerosolization Module for an Aerosol Generating System

Abstract

An aerosolization module for an aerosol generating device includes a reservoir and a first cover made of a resilient material and fitted into an opening of the reservoir. The first cover forms a channel which extends from outside the reservoir to its inner volume. The channel makes it possible to fill the reservoir with vaporizable material. The aerosolization module further includes a second cover configured to be mounted on the first cover, the second cover including a protrusion configured to tightly plug the channel formed by the first cover and thereby close the reservoir when the second cover is mounted on the first cover. The aerosolization module is easy to fill and easy to assemble. A method of assembling the aerosolization module is also provided.

1 . An aerosolization module for an aerosol generating device comprising:
 a reservoir comprising at least one wall that defines an inner volume adapted to receive a vaporizable material, said at least one wall defining an opening,   a first cover made of a resilient material, the first cover being fitted into the opening and forming a channel which extends from outside the reservoir to the inner volume of the reservoir, the channel making it possible to fill the reservoir with the vaporizable material to be aerosolized; and   a second cover configured to be mounted on the first cover, the second cover comprising a protrusion configured to plug the channel formed by the first cover and thereby close the reservoir when said second cover is mounted on the first cover.   
     
     
         2 . The aerosolization module according to  claim 1 , wherein the first cover is made of silicone. 
     
     
         3 . The aerosolization module according to  claim 1 , wherein the second cover is made of silicone. 
     
     
         4 . The aerosolization module according to  claim 1 , wherein the opening is located at an opposite end to a mouthpiece of the aerosolization module. 
     
     
         5 . The aerosolization module according to  claim 1 , further comprising a heater assembly comprising a heater and a heater holder, the heater assembly being fastened to the reservoir. 
     
     
         6 . The aerosolization module according to  claim 5 , wherein the heater holder comprises a through-hole aligned with the channel formed by the first cover. 
     
     
         7 . The aerosolization module according to  claim 6 , wherein the reservoir and the heater holder form a central tube in the aerosolization module, the heater extending along the central tube. 
     
     
         8 . The aerosolization module according to  claim 7 , wherein the heater is installed in the central tube, is wrapped around the central tube, or forms a portion of the central tube. 
     
     
         9 . The aerosolization module according to  claim 7 , wherein the central tube comprises at least one lateral hole to feed the heater with vaporizable material contained in the reservoir. 
     
     
         10 . The aerosolization module according to  claim 7 , wherein the first cover and the second cover define a path for providing air to the central tube. 
     
     
         11 . The aerosolization module according to  claim 5 , wherein the heater is surrounded by a porous material, which regulates a flow of vaporizable material from the reservoir to the heater. 
     
     
         12 . The aerosolization module according to  claim 1 , further comprising electrical contacts mounted on the second cover, the electrical contacts being adapted for electrical connection of the aerosolization module to a battery module. 
     
     
         13 . An aerosol generating device comprising the aerosolization module according to  claim 1 , and a battery module connected to the aerosol generating device. 
     
     
         14 . A method for assembling an aerosolization module, the method comprising the steps of:
 providing a reservoir, a first cover, and a second cover,   fitting the first cover into an opening of the reservoir, the first cover forming a channel which extends between outside the reservoir and an inner volume of the reservoir,   filling the reservoir with vaporizable material by the channel, and   mounting the second cover on the first cover, thereby plugging the channel with a protrusion of the second cover.   
     
     
         15 . The method according to  claim 14 , further comprising the steps of:
 before fitting the first cover, fastening a heater assembly comprising a heater and a heater holder to the reservoir or to the first cover; and   mounting electrical contacts on the second cover, the electrical contacts being configured, once mounted on the second cover, to provide the heater with electricity.
