         5 . The appliance of  claim 1 , wherein the gasket comprises a further seal extending around an upstream end of the gasket. 
     
     
         6 . The appliance of  claim 5 , wherein the outer wall comprises an upstream end and the further seal engages with the upstream end of the outer wall. 
     
     
         7 . The appliance of  claim 6 , wherein the outer wall comprises first part and a second part, wherein the second part comprises the upstream end of the outer wall. 
     
     
         8 . The appliance of  claim 7 , wherein the first part engages with the seal and the centralising feature. 
     
     
         9 . The appliance of  claim 7 , wherein the second part comprises an annulus having a flange and the first part comprises a cooperating projection wherein the flange engages against the cooperating projection of the first part. 
     
     
         10 . The appliance of  claim 9 , wherein the further seal urges the flange against the cooperating projection. 
     
     
         11 . The appliance of  claim 1 , wherein the centralising feature comprises a convex surface extending from the inner wall towards the outer wall. 
     
     
         12 . The appliance of  claim 11 , wherein the convex surface is hemispherical. 
     
     
         13 . The appliance of  claim 1 , wherein the outer wall comprises an inner surface and the inner surface comprises a cooperating centralising feature. 
     
     
         14 . The appliance of  claim 13 , wherein the cooperating centralising feature comprises a plurality of discrete points of contact radially disposed around the inner surface. 
     
     
         15 . The appliance of  claim 14 , wherein the cooperating centralising feature comprises at least three ribs extending radially inwards of the inner surface towards the inner wall. 
     
     
         16 . The appliance of  claim 15 , wherein the at least three ribs comprises four ribs. 
     
     
         17 . The appliance of  claim 13 , wherein the centralising feature only engages with the cooperating centralising feature. 
     
     
         18 . The appliance of  claim 1 , wherein the seal extends continuously around the gasket. 
     
     
         19 . The appliance of  claim 1 , wherein the seal extends continuously between the outer wall and the inner wall.
