Closure cap for a container for receiving medical liquids, and container for receiving medical liquids
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.
1. A closure cap for a container for receiving medical liquids having a cover portion and a rim portion, comprising:
an injection part for the injection of a medical liquid being arranged in the cover portion; wherein the injection part comprises:
an injection 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, wherein the injection outward-pointing portion for connection is sealed off by a break-off part which is connected to a top end of the injection outward-pointing portion for connection via an annular zone for fracture, the break-off part having a lateral tab for gripping which extends to the rim portion of the closure cap, and
an injection inward-pointing closing-off portion which has a self-sealing membrane to close off the conical recess in the portion for connection, wherein the self-healing membrane is slit;
and
a withdrawal part to allow a medical liquid to be withdrawn, wherein the withdrawal part comprises:
a withdrawal outward-pointing portion for connection having a recess for receiving a spike, and
a withdrawal inward-pointing closing-off portion which has a piercable membrane for closing off the recess in the withdrawal outward-pointing connection, the closing-off portion being closed off by a break-off part which is connected to the a top end of the withdrawal outward-pointing portion for connection via an annular zone for fracture, the break-off part having a lateral tab for gripping which extends to the rim portion of the closure cap.
2. A closure cap according to claim 1 , wherein the self-sealing membrane is inserted in the recess of the inward-pointing closing-off portion of the injection part by a snap fit.
3. A closure cap according to claim 2 , wherein the inward-pointing closing-off portion of the injection part has an inwardly projecting rim which fixes the self-sealing membrane in place in the recess in the closing-off portion of the injection part by a clamping action.
4. A closure cap according to claim 1 , wherein the inward-pointing closing-off portion of the injection part is configured to compress the self-sealing membrane in the axial direction in the recess of the injection part when the conical tip of an injection syringe is inserted, to thereby cause the membrane to be opened.
5. A closure cap according to claim 1 , wherein the recess in the inward-pointing closing-off portion 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. A closure cap according to claim 5 , wherein the self-sealing membrane has an annular section which is arranged in the second cylindrical section of the recess of the injection part, 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. A closure cap according to claim 6 , wherein the dished section of the self-sealing membrane has a bowl-like depression.
8. A closure cap according to claim 1 , wherein the outward-pointing connection portion of the injection part has an outside thread.
9. A closure cap according to claim 1 , wherein the outward-pointing connection portion is sealed off by a break-off part which is connected to one end of the connection portion via an annular fracture zone.
10. A closure cap according to claim 1 , wherein the piercable membrane in the withdrawal part is inserted in the recess of the withdrawal outward-pointing connection portion by a snap fit.
11. A closure cap according to claim 10 , wherein the closing-off portion of the withdrawal part has an inwardly projecting rim which fixes the piercable membrane in place in the recess of the outward-pointing connection portion by a clamping action.
12. A closure cap of claim 1 , wherein the closure cap is a blow-fill-seal (BFS) container.
