Abstract
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 (3a) and a flange-like rim portion (2), wherein the rim portion (2) extends from the side wall (3a) 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 (3a) until it reaches the side wall, and—curing the sealing composition (4) after the migration towards the side wall (3a).
