Reservoir for refilling an article of an aerosol provision system

Abstract

A reservoir for refilling an article of an aerosol provision system includes a reservoir body configured to store aerosol-generating material, and a moveable component within the reservoir body. The moveable component is configured to move within the reservoir body as aerosol generating material is transferred from the reservoir. The moveable component co-operates with an internal surface of the reservoir body to prevent the reservoir from being refilled with aerosol-generating material.

1 . A reservoir for refilling an article of an aerosol provision system, comprising:
 a reservoir body configured to store aerosol-generating material; and   a moveable component within the reservoir body and configured to move within the reservoir body as aerosol generating material is transferred from the reservoir,   wherein the moveable component co-operates with an internal surface of the reservoir body to prevent the reservoir from being refilled with aerosol-generating material.   
     
     
         2 . The reservoir of  claim 1 , further comprising a reservoir outlet, wherein aerosol-generating material is transferred from the reservoir through the reservoir outlet. 
     
     
         3 . The reservoir of  claim 2 , wherein the moveable component is configured to move towards the reservoir outlet as aerosol generating material is transferred from the reservoir. 
     
     
         4 . The reservoir of  claim 2 , wherein the reservoir body comprises an opening at a side of the reservoir body opposite the reservoir outlet. 
     
     
         5 . The reservoir of  claim 2 , wherein reservoir body comprises a neck configured to engage with a refilling device, and the reservoir outlet is located at the neck. 
     
     
         6 . The reservoir of  claim 1 , wherein the internal surface of the reservoir body comprises a ridge configured to engage with the moveable component to prevent the reservoir from being refilled with aerosol-generating material. 
     
     
         7 . The reservoir of  claim 6 , wherein the ridge extends around a perimeter of the internal surface of the reservoir body. 
     
     
         8 . The reservoir of  claim 6 , wherein the internal surface of the reservoir body comprises a plurality of ridges circumferentially distributed around a perimeter of the internal surface of the reservoir body. 
     
     
         9 . The reservoir of  claim 7 , wherein the moveable component comprises one or more flanges at one end of the moveable component, the flanges extending radial outwards and configured to engage with the ridge when the moveable component has moved past the ridge to prevent the moveable component from moving back past the ridge. 
     
     
         10 . The reservoir of  claim 1 , wherein the moveable component comprises an o-ring configured to co-operate with the internal surface of the reservoir body. 
     
     
         11 . The reservoir of  claim 10 , wherein the moveable component further comprises a stopper, wherein the stopper is configured to move within the reservoir body separately from the o-ring in order to prevent the reservoir from being refilled with aerosol-generating material. 
     
     
         12 . The reservoir of  claim 6 , wherein reservoir body comprises a neck configured to engage with a refilling device, and wherein the ridge is located at the neck. 
     
     
         13 . The reservoir of  claim 12 , wherein the moveable component comprises a neck configured to fit inside the neck of the reservoir body, the neck of the moveable component comprising a clip extending radially outwards and configured to engage with the ridge when the neck of the moveable component has moved past the ridge to prevent the moveable component from moving back past the ridge. 
     
     
         14 . The reservoir of  claim 13 , wherein the moveable component comprises a seal and a stopper, the seal comprises an opening, the neck of the moveable component is on the stopper, and the neck of the moveable component passes through the opening in the seal. 
     
     
         15 . The reservoir of  claim 12 , wherein the moveable component comprises a seal and a stopper, the seal comprises a neck configured to fit inside the neck of the reservoir body, the neck of the seal comprising a groove extending radially inwards from the neck of the seal and configured such that the ridge fits inside the groove to prevent the reservoir from being refilled with aerosol-generating material. 
     
     
         16 . The reservoir of  claim 1 , wherein the moveable component comprises a seal and a stopper, the seal is configured to co-operate with the internal surface of the reservoir body, and the stopper is configured to move within the reservoir body separately from the seal in order to prevent the reservoir from being refilled with aerosol-generating material. 
     
     
         17 . The reservoir of  claim 16 , wherein a portion of the stopper tapers inwardly compared to the internal surface of the reservoir body, and the stopper is caused to move separately from the seal due to a deflection of a central portion of the seal. 
     
     
         18 . The reservoir of  claim 16 , wherein the seal is annular in shape and comprises an opening at the center of the seal, a portion of the stopper passes through the opening in the seal, and a radially outer portion of the seal engages with a radially outer portion of the internal surface of the reservoir body.
