Abstract

The invention relates to a closure cap (1) for a container (2) for receiving a pharmaceutical substance, in particular for an infusion or transfusion bottle, with a flanged cap (4) which is suitable for engagement around a container neck (8) and which has a metal film layer, wherein the flanged cap (4) also has a recess (5) that is covered by a plastic lid (3), the plastic lid (3) is connected to the flanged cap (4) by means of at least one connection element (9) formed on the underside, and the plastic lid (3) is removable at least in part. In order to provide a closure cap for a container for receiving a pharmaceutical substance, which container is safe to handle and meets strict demands regarding its tamper-proofing, it is proposed that the plastic lid (3) is connected to the flanged cap (4) via a plurality of connection elements (9) which are formed on its underside and pass through associated connection openings (11) formed in the flanged cap (4), and that the plastic lid (3), in order to expose the recess (5), has a tear-off tab (12) which extends from a coverage of the recess (5) as far as an edge of the plastic lid (3), wherein no connection between the plastic lid and the flanged cap (4) is formed in the area of the tear-off tab (12).

Claims

1. Closure cap (1) for a container (2) for receiving a pharmaceutical substance, in particular for an infusion or transfusion bottle, having a flanged cap (4) which is suitable for engaging around a container neck (8) and which has a metal foil layer, the flanged cap (8) also having a cut-out (5) which is overlaid by a plastics cover (3), the plastics cover (3) being connected in a holding manner to the flanged cap (4) by means of at least one connecting element (9) formed on the underside, and the plastics cover (3) being removable at least in part, wherein the plastics cover (3) is connected to the flanged cap (4) by way a plurality of connecting elements (9) formed on the underside of the cap and engaging through connecting openings (11) formed for this purpose in the flanged cap (4), and wherein the plastics cover (3) has a tear-off tab (12) for exposing the cut-out (5), the tab extending from a location overlying the cut-out (5) as far as an edge of the plastics cover (3) without any connection being formed between the plastics cover and the flanged cap (4) in the region of the tear-off tab (12).

2. Closure cap according to claim 1, wherein the plastics cover (3) remains connected to the flanged cap (4) by way of the connecting elements (9) even after the opening has been exposed.

3. Closure cap according to claim 1, wherein more than two connecting elements (9) are provided, preferably four.

4. Closure cap according to claim 1, wherein the connecting elements (9) are distributed at equal angular intervals.
