Sealing cap for a container for holding a medical liquid
A sealing cap for a container for holding a medical liquid comprising a cap body, which bounds an interior and has at least one opening, and at least one connection device, which is arranged on the cap body and to which a conveying device for feeding a medical liquid into the container or for removing a medical liquid from the container can be connected. The connection device has a sealing element, arranged on the cap body. The connection device has a break-off piece, which, in an initial state, is firmly connected to the cap body and covers the outer face of the sealing element in the outward direction. The break-off piece is connected to the cap body by means of a pre-determined breaking point. In addition, the sealing element is convex on the outer face.
1. A sealing cap for a container for holding a medical liquid, the sealing cap comprising
a cap body and
a connecting device that is arranged on the cap body,
wherein the connecting device comprises
a sealing element arranged on the cap body to seal an opening in the cap body, the sealing element comprising an outside surface that faces away from an interior defined by the cap body and being convex on the outside surface thereof, wherein the outside surface of the sealing element protrudes outward in relation to a top surface off the cap body,
a break-off part that, in an initial state, is fixedly connected to the cap body and covers the outside surface of the sealing element, and
a pre-determined breaking point that connects the break-off part to the cap body such that the break-off part detaches from the cap body along the predetermined breaking point,
wherein the connecting device is connectable to a conveying device that is able to be positioned against the outside surface while conveying medical liquid into the container or drawing medical liquid from the container.
2. The sealing cap as claimed in claim 1 , wherein an interior between the break-off part and the outside surface of the sealing element is sterile.
3. The sealing cap as claimed in claim 1 , wherein a sealing head of the sealing element extends through the opening and forms the outside surface.
4. The sealing cap as claimed in claim 1 , wherein a center of the convex outside surface of the sealing element is above an outer upper edge of a sealing head of the sealing element, wherein the distance between the center and the outer upper edge is between 0.3 millimeters and 0.7 millimeters.
5. The sealing cap as claimed in claim 1 , wherein the predetermined breaking point extends around the opening.
6. The sealing cap as claimed in claim 1 , wherein the connecting device is a first connecting device for removing a medical liquid and wherein the sealing cap further comprises a second connecting device for supplying a medical liquid.
7. The sealing cap as claimed in claim 6 , wherein each connecting device comprises a sealing element and wherein the sealing elements of the connecting devices are identical in structure.
8. The sealing cap as claimed in claim 7 , wherein each sealing element comprises a sealing head, which forms the outside surface, and a sealing body which connects to the sealing head, wherein a ring collar that holds the sealing body on a holding device extends around the positioning direction and wherein a flange connects the ring collar to the sealing body.
9. The sealing cap as claimed in claim 6 , wherein each connecting device comprises a sealing element and wherein the sealing elements of the connecting devices differ from each other in structure.
10. The sealing cap as claimed in claim 9 , wherein the sealing element of the first connecting device comprises a sealing head, which realizes the outside surface, and a sealing body, which connects to the sealing head, wherein a ring collar that extends around the positioning direction holds the sealing body on a first holding device of the cap body, and wherein a flange connects the ring collar to the sealing body.
11. The sealing cap as claimed in claim 9 , wherein the sealing element of the second connecting device comprises a sealing head, which forms the outside surface, and a sealing body, which connects to the sealing head and wherein and edge portion, which extends around the positioning direction, holds the sealing body on a second holding device of the cap body.
12. The sealing cap as claimed in one of claim 9 , wherein the sealing elements, when viewed along the positioning direction, comprise a different thickness which is to be pierced by the conveying device.
13. The sealing cap of claim 1 , wherein the sealing element comprises a sealing head having an outer edge and a convex portion on an outside surface that is remote from an interior of the container and wherein a center of the convex outside surface is between 0.3 millimeters and 0.7 millimeters above the outer edge.
14. The sealing cap of claim 1 , wherein the sealing element comprises a sealing head having an outer edge and a convex portion on an outside surface that is remote from an interior of the container and wherein a center of the convex outside surface is between 0.3 millimeters and 0.7 millimeters above the outer edge.
15. A manufacture comprising: a bottle including a sealing cap as recited in claim 1 .
16. The manufacture of claim 15 , wherein the bottle is filled with an infusion solution.
