Beta container for an alpha-beta port system

A beta container for an alpha-beta port system, the beta container comprising:

• a sheath for receiving a transport material;
• a flange part, the flange part comprising:
• a through opening for transferring the transport material into or out from the sheath,
• a first interface designed for reversible connecting to an alpha connection of the alpha-beta port system, and
• a second interface designed for releasably attaching a beta cover that closes the through opening;
• wherein an edge of the sheath is connected in a material-fitting manner to a first surface of a ring that encompasses around a jacket surface of the flange part, the first surface and the jacket surface comprising different materials;
• and
• a first seal arranged between the ring and the jacket surface.

A method of sterilely transferring material from a container interior into or out from an isolation space of an alpha-beta port system, the method comprising:

• obtaining beta container, wherein the beta container comprises:
• a sheath for receiving a transport material, and
• a flange part, the flange part comprising:
• a through opening for transferring the transport material into or out from the sheath,
• a first interface designed for reversible connecting to an alpha connection of the alpha-beta port system, and
• a second interface designed for releasably attaching a beta cover that closes the through opening,
• wherein at least one of:
• an edge of the sheath is connected in a material-fitting manner to a first surface of a ring that encompasses around a jacket surface of the flange part, the first surface and the jacket surface comprising different materials,
• an elastic bellows is fastened to the flange part in such a way that, in a relaxed state, the bellows is compressible and at least one of engages over the second interface or projects out of the through opening on a side facing away from the sheath, or
• at least one transponder designed for transmitting an identification is arranged at the flange part;
• and
• at least one of:
• transmitting an identification by the transponder,
• reversibly connecting the beta container via its first interface to an alpha port of the alpha-beta port system, connecting a beta cover of the beta container to an alpha door of the alpha port, and opening the beta cover, or
• relaxing the bellows such that the bellows at least one of overlaps the second interface or protrudes from the through opening.
