Abstract

The invention relates to a closure cap for a container filled with a medical liquid. The closure cap has at least one connection with a scaling element which can be pierced by a spike or a needle to remove the medical fluid. A flap is arranged on an inner side of the closure cap and is connected to the main body by means of a hinge. The sealing element is fixed to the closure cap by the flap folded against the main body.

First claim

The invention claimed is:

1. A closure cap for a container filled with a medical liquid, the closure cap comprising:
a base body and at least one connection with a sealing element which can be pierced with a spike or a needle to remove the medical liquid, and
a flap arranged inside on an underside of the base body of the closure cap and connected to the base body by a hinge,
the sealing element being fixed to the closure cap by the flap folded against the base body.

2. The closure cap according to claim 1 , wherein the sealing element is closed with a tamper-evident closure, in particular is covered with a break-off piece which is connected to the base body of the closure cap via a predetermined breaking point surrounding the sealing element.

3. The closure cap according to claim 1 , wherein the sealing element has a circumferential ring which sits in a groove of the base body and/or the flap.

4. The closure cap according to claim 1 , wherein the flap folded against the base body is latched to the base body.

5. The closure cap according to claim 1 , wherein the flap is designed as a plate with at least one opening in which a piercing region of the sealing element is located.

6. The closure cap according to claim 1 , wherein the hinge is designed as a film hinge.

7. The closure cap according to claim 1 , wherein the closure cap has at least two connections, each with a sealing element.

8. The closure cap according to claim 7 , wherein the flap is designed as a single flap which fixes the sealing elements of the at least two connections to the closure cap.

9. The closure cap according to claim 1 , wherein the hinge is arranged on a long side of the flap, wherein the flap is latched to the base body on an opposite long side.

10. The closure cap according to claim 9 , wherein a latching body of the base body engages around a corner of the opposite long side of the flap.

11. The closure cap according to claim 10 , wherein the corner is rounded.

12. The closure cap according to claim 1 , wherein the base body and the flap are part of a one-piece plastic injection-molded part.

13. The closure cap according to claim 7 , where the closure cap has exactly two connections, each with a sealing element.

14. A container filled with a medical liquid comprising a closure cap according to claim 1 .

15. The container according to claim 13 , wherein the container comprises a bottle produced using a Blow-Fill-Seal (BFS) or a Strech-Blow-Molding (SBM) process.

16. The container according to claim 15 , wherein the container is sterilized.

17. A method for assembling a closure flap for a container filled with a medical liquid, in particular for the container according to claim 14 , comprising the steps:
providing a closure cap which has a base body with at least one opening for a connection, wherein the closure cap has inside on an underside of the base body a flap with at least one opening which can be folded relative to the base body;
inserting a sealing element inside in front of the opening of the base body or in front of the opening of the flap; and
folding the flap onto the base body, wherein the flap is fixed in an end position on the base body and the sealing element is fixed between the opening of the base body and the opening of the flap.

18. The method according to claim 17 , wherein the sealing element is inserted into the opening of the base body or the flap in such manner that it is held centred centered and securely in position.
