FIELD: sealing devices.
SUBSTANCE: sealing device formed of synthetic material having properties identical to or better than stopper cork properties may be used in all stopper cork applications. Sealing device is used to seal vine or strong drink containers. The sealing device is formed by thermoshaping of elastomeric material, wherein the foamed elastomeric material is obtained by foaming supercritical fluid medium.
EFFECT: possibility to take initial shape after compression, improved gas permeability, possibility to use corkscrew to extract the sealing device from container without the risk of container content pollution with sealing device materials or substances.
