the first opening obturated by a first pierceable self-sealing membrane, and the injection site configured to provide access to a second opening for injecting the additive, the second opening obturated by a second pierceable self-sealing membrane, the first and second pierceable membranes having different configurations; and
shoulders for engaging beneath at least one of the first and second membranes, said shoulders having a first position for receiving the at least one of the first and second membranes, and a second position for anchoring the at least one of the first and second membranes. Description
The present invention relates to a closing cap for a container which is filled with a medical liquid, in particular for infusion or transfusion, in particular a bottle-shaped container filled with a liquid for parenteral feeding. Moreover, the invention relates to a container for a medical liquid for infusion or transfusion, in particular a bottle-shaped container to be filled with a liquid for parenteral feeding, which has one such closing cap.
An objective of the present invention is to make available a closing cap for containers with a removal and injection site which are filled with medical liquids, in particular liquids for infusion or transfusion, said closing cap permitting reliable handling when removing the medical liquid and injecting the additive.
The membrane of the removal site can be configured in such a way that the port can be pierced with a piercing part (spike), the spike being held fast in the presence of tensile load and the removal site being securely sealed, whilst the membrane of the injection site can be designed in such a way that the port is tight after puncturing and removal of the cannula.
The self-sealing membrane of the removal site preferably has an outer annular portion, which is followed by a middle annular portion with an upper and lower seating face, said middle annular portion being held in a clamped manner in the cap. The middle annular portion transforms into an inner plate-shaped portion, at the upper side of which a trough-shaped recess is formed. The inner plate-shaped portion preferably has a flat underside. The special configuration of the membrane ensures on the one hand that the spike is guided and held securely when piercing the membrane and on the other hand guarantees that, after withdrawal of the spike, the membrane reliably seals again even in the presence of relatively high internal pressure in the container. It has been shown in tests that the special configuration of the membrane is decisive for the immediate re-sealing, the sealing of the membrane being increased further with increasing internal pressure in the packaging.
FIG. 1 shows a first example of an embodiment of the closing cap according to the invention in a cut-away view.
Lid part 2 of cap 1 has two openings 8, 9 with a preferably circular cross-section, said openings being arranged at a distance from one another. A first self-sealing membrane 10 for removal site 6 sits in first opening 8 and a second self-sealing membrane 11 for the injection site in second opening 9. The two membranes are configured differently. They are made from an elastic material, preferably from a synthetic rubber, preferably from polyisoprene.
Second membrane 11 for injection site 7, which is thicker than first membrane 10, has an outer annular portion 11 a with an upper and lower seating face, said outer annular portion being held in a clamped manner in the cap. Annular portion 11 a is followed directly by an inner plate-shaped portion 11 b, at the upper and lower side of which an upper and a lower trough-shaped recess 11 c, 11 d are formed. Trough-shaped recesses 11 c and 11 d of second membrane 11 have a smaller depth than trough-shaped recess 10 d of first membrane 10.
The two membranes 10, 11 are held in a clamped manner by means of a retaining plate 13, which is inserted in a snap-in or lock-in manner into side part 3 of the cap. The edge of retaining plate 13 sits in an annular groove 14, which runs at the inside of side part 3 beneath lid part 2.
Membranes 10, 11 are first inserted into openings 8, 9 (FIG. 3 a). Shoulders 15′, 16′ are then turned up in such a way that they lie adjacent to the lower seating faces of the membranes, so that the membranes are held in a clamped manner. In the case of membrane 11 of injection site 7, it is sufficient to bend shoulder 16′ through 90°. Shoulder 15′ of removal site 6, on the other hand, is flanged around outer annular portion 10 a of the membrane (FIG. 3 b).
FIG. 5 shows a bottle-shaped container 33 which is obturated with closing cap 1. Closing cap 1 is welded fast to head 34 of bottle. A rubber gasket (not shown) sits between closing cap 1 and bottle head 34. The container is filled with a liquid for parenteral feeding. The container can however also be filled with an infusion or transfusion solution.
