  • Publication number: 20210300643
    Abstract: A sealing cap for a container for holding a medical liquid comprises a cap body and a connection device having a sealing element arranged on the cap body. The sealing element is arranged at the opening and is retained in the cap body in a clamped manner by a, preferably annular, flanged rim. The connection device has a break-off piece, which is firmly connected to the cap body and covers an outer face of the sealing element in the outward direction. The break-off piece is integral with the cap body, is connected to the cap body by a predetermined breaking point where the break-off piece can be detached from the cap body. The sealing element outer face is substantially flat and is accessible for wiping to provide a sealing cap having a sealing element arranged that can be simply and reliably disinfected.

  • Patent number: 11013663
    Abstract: A container for a medical liquid, comprising a connection piece via which a medical liquid can be pumped into or out of the container, an attachment part which can be attached to the connection piece and connected to a pump device to pump a medical liquid or out of the container, and a sealing element for sealing a passage between the connection piece and the attachment part. The sealing element has a slot opening which is closed against a liquid flow when the pump device is not attached to the attachment part and which is open when the pump device is attached to the attachment part such that a medical liquid can be pumped through the slot opening. The attachment part has a connection portion with an opening into which the connection piece can be inserted along an insertion direction in order to connect to the attachment part.
