The present invention proposes a method for providing a rubber-elastic sealing member onto a capsule ( 1 ) intended for producing a beverage in a beverage production device, wherein the capsule has a body portion ( 3 ) having a side wall ( 3 a ) and a flange-like rim portion ( 2 ), wherein the rim portion ( 2 ) extends from the side wall ( 3 a ) of the body portion ( 3 ), the method comprising the steps of: —applying an uncured sealing composition ( 4 ) in a liquid or viscous state onto the rim portion ( 2 ) of the capsule ( 1 ), —heating said applied sealing composition ( 4 ) such that the sealing composition at least partially migrates towards the side wall ( 3 a ) until it reaches the side wall, and—curing the sealing composition ( 4 ) after the migration towards the side wall ( 3 a ). |
