Container having a base and a lid

Abstract

A container for a tobacco product having a base and a lid, the lid comprises an outer skirt and a first abutment projection. The abutment projection runs circumferentially on an inside surface of the lid, adjacent to the outer skirt. The base comprises a side wall configured to contact an outward-facing surface of the first abutment projection during closure of the lid, such that the side wall is outwardly deflected and contacts an inside surface of the outer skirt of the lid, sealing the container when the lid is closed.

1 . A container for a tobacco product comprising:
 a lid comprising:
 an outer skirt; and 
 a first abutment projection, the abutment projection running circumferentially on an inside surface of the lid, adjacent to the outer skirt; and 
   a base comprising a side wall configured to contact an outward-facing surface of the first abutment projection during closure of the lid, such that the side wall is outwardly deflected and contacts an inside surface of the outer skirt, sealing the container when the lid is closed.   
     
     
         2 . The container of  claim 1  wherein, during closure, the outward-facing surface of the first abutment projection is angled relative to the side wall of the base to improve the deflection of the side wall of the base upon closure of the container. 
     
     
         3 . The container of  claim 1  wherein the side wall of the base contacts both the inside wall of the outer skirt and the first abutment projection when the lid is closed. 
     
     
         4 . The container of  claim 1  wherein the first abutment projection forms a complete circumferential loop on the inside surface of the lid. 
     
     
         5 . The container of  claim 1  further comprising a releasable retention mechanism, the releasable retention mechanism comprising:
 a lid coupling portion positioned on an inward-facing surface of the outer skirt; and 
 a base coupling portion positioned on an outward-facing surface of the side wall of the base, 
 wherein the coupling portions are configured to engage upon closure of the lid such that the lid is retained in the closed position, 
 wherein the engaged coupling portions are configured to release upon application of an appropriate force by a user. 
 
     
     
         6 . The container of  claim 1  further comprising a second abutment projection, wherein the second abutment projection is positioned on an inward facing surface of the outer skirt and is configured to contact the side wall of the base upon closure of the container. 
     
     
         7 . The container of  claim 1  wherein there are at least three contact points between the lid and base when the container is closed. 
     
     
         8 . The container of  claim 1  wherein a portion of the base side wall is angled inwards so as to increase the contact force between the side wall and the first abutment projection of the lid upon closure. 
     
     
         9 . The container of  claim 1  wherein a tip of the base side wall is angled outwards such that contact between a tip of the side wall and an inward facing surface of the outer skirt is increased upon closure. 
     
     
         10 . The container of  claim 1  wherein at least a portion of the container is made from a tailored oxygen transmission polymer. 
     
     
         11 . The container of  claim 1  further comprising tobacco contained therein.
