Abstract

Sealing piston includes a breaker shaped body formed from a resin of sufficient rigidly to provide a rigid form for the piston. The body has a ring shaped wall with a wall surface located at a small and equal distance from the inner wall of the capsule, when the piston is located inside the capsule. A sealing material is attached to the body consisting of a considerably softer and elastic resin material than the resin material of the body with the sealing material extending as a thin layer over the whole outer surface of the ring wall. The sealing material is connected to the outer surface by a resin to resin connection with the ring wall pressing the sealing material firmly against the inner surface of the capsule in order to fit the sealing material to the shaoe of the inner surface when the piston is inside the capsule.
