Definitions
- the invention relates to a closure cap for a container filled with a medicinal liquid, which container is designed in particular as a bottle.
- the invention also relates to a method for assembling the closure cap of a medical container.
- containers for the storage of medical liquids, such as infusion solutions, containers, in particular bottles, are known which have a piercing sealing element in order to remove the liquid by means of a transfer device, for example by means of a spike of a transfer system, or to remove liquid, such as a pharmaceutical active ingredient f to be injected into the medicinal container, for example by means of a needle syringe.
- the sealing element is in particular resealable and is pierced with a spike or a needle.
- Spikes are secretly referred to as hollow needles that have a larger diameter than metal needles and are mostly made of plastic or metal.
- a base body made of plastic is blown, then filled with the medicinal liquid, hermetically sealed and finally connected to a closure cap, which is provided with the sealing element.
- Such a container is known in particular from document WO 2016/156 242 A1 (Fresenius Kabi GmbH).
- the closure cap shown in this document comprises a sealing element that is convex on the upper side.
- the sealing element can be wiped off easily, which is required by regulatory provisions in some countries.
- the sealing element In order to fix the sealing element in the cap, the sealing element has an annular, axially extending web at the edge on the upper side and the lower side, which is seated in a complementary groove of the closure cap.
- this can be inserted into the cap when viewed from the inside.
- a collar of the closure cap that extends around the sealing element is then crimped so that the sealing element is fixed and clamped in such a way that adequate tightness is ensured and the sealing element is held securely.
- the beading of the collar requires a suitable system for this purpose, which can be constructed in a complex manner for the specific system, in particular if this is located, for example, in an aseptic part of the production system.
- the invention is based on the object of simplifying the assembly of the sealing element or sealing elements of a closure cap for a container filled with a medicinal liquid.
- the closure cap should be particularly safe, both when it is assembled and when it is subsequently used in the assembled state on the medical container.
- the object of the invention is already achieved by a closure cap for a container filled with a medicinal liquid and by a method for fitting a closure cap for a container filled with a medicinal liquid according to one of the independent claims.
- the invention relates to a closure cap for a container filled with a medicinal liquid, the closure cap having at least one connection with a sealing element which can be pierced with a spike or a needle to remove the medicinal liquid, on an inside of the closure cap a flap is arranged, which is connected to the base body by means of a hinge, and wherein the sealing element is fixed on or in the closure cap by the flap folded against the base body.

- connections can also be provided by different sealing elements, for example a connection for a spike (for removal) and a further connection for a needle (for addition).
- a Luer connection for connecting a Luer syringe or a Luer lock syringe can also be provided, for example.
- all sealing elements are designed to be wipeable.
- the flap is preferably designed as a single flap which fixes the sealing elements of the at least two connections on or in the closure cap.
- the flap can also have two or more through-holes, which in the installed state overlap with the piercing area of a respective sealing element.
