Abstract

The invention relates to a closure cap for a container for receiving medical liquids, in particular a BFS vial which is produced by a blow-fill seal process, and to a BFS container with such a closure cap. The closure cap according to the invention has a cover part and an edge part, with an injection part arranged in the cover part. The injection part has an outwardly directed connection part with a conical recess for receiving the cone stem of a needleless injection syringe in a seal-forming manner, and an inwardly directed closure part which has a self-sealing membrane for closing the recess of the connection part. The self-sealing membrane is slotted. The closure cap according to the invention allows a liquid to be injected without use of an injection needle.

Claims

1. Closure cap for a container for receiving medical liquids, and in particular a BFS container, which closure cap has a cover portion and an rim portion, characterised in that there is arranged in the cover portion an injection part for the injection of a medical liquid which has an outward-pointing portion for connection having a conical recess to receive the conical tip of a needleless injection syringe while forming a seal against it, and an inward-pointing closing-off portion which has a self-sealing membrane to close off the recess in the portion for connection, which self-sealing membrane is slit.

2. Closure cap according to claim 1, characterised in that the closing-off portion of the injection part has a recess in which the self-sealing membrane is inserted by being snapped into place.

3. Closure cap according to claim 1, characterised in that the closing-off portion of the injection part has an inwardly projecting rim which fixes the self-sealing membrane in place in the recess by a clamping action.

4. Closure cap according to claim 1, characterised in that the closing-off portion of the injection part having the self-sealing membrane is so designed that, when the conical tip of an injection syringe is inserted, the membrane is compressed in the axial direction in the recess, thus causing the membrane to be opened.

5. Closure cap according to claim 1, characterised in that the recess in the closing-off portion of the injection part has a first cylindrical section which merges with the cover portion, and a second cylindrical section which follows on from the first cylindrical section and which is of a larger inside diameter than the first cylindrical section.

6. Closure cap according to claim 5, characterised in that the self-sealing membrane has an annular section which is arranged in the second cylindrical section of the recess, and a dished section which follows on from the annular section by way of a central web and which is arranged in the first cylindrical section.

7. Closure cap according to claim 6, characterised in that the dished section of the self-sealing membrane has a bowl-like depression.

8. Closure cap according to claim 1, characterised in that the portion for connection of the injection part has an outside thread.

9. Closure cap according to claim 1, characterised in that the portion for connection is sealed off by a break-off part which is connected to the top end of the portion for connection via an annular zone for fracture.

10. Closure cap according to claim 9, characterised in that the break-off part has a lateral tab for gripping which extends to the rim portion of the closure cap.

11. Closure cap according to claim 1, characterised in that there is arranged in the cover portion a withdrawal part to allow a medical liquid to be withdrawn with a spike, which withdrawal part has an outward-pointing portion for connection having a recess for receiving a spike, and an inward-pointing closing-off portion which has a piercable membrane for closing off the recess in the part for connection.

12. Closure cap according to claim 11, characterised in that the piercable membrane in the withdrawal part is inserted in the recess by being snapped into place.

13. Closure cap according to claim 12, characterised in that the closing-off portion of the withdrawal part has an inwardly projecting rim which fixes the piercable membrane in place in the recess by a clamping action.

14. Closure cap according to claim 11, characterised in that the closing-off portion of the withdrawal part is closed off by a break-off part which is connected to the top end of the portion for connection via an annular zone for fracture.

15. Closure cap according to claim 14, characterised in that the break-off part of the withdrawal part has a lateral tab for gripping which extends to the rim portion of the
