Patent ID: 8672155

Claim:
A closure cap, for a container filled with a medical liquid which has a mouth section sealed with a pierceable membrane, having a main closure body in cap form which has a covering part and a skirt part, a drinking nozzle, having an opening for drinking from, which can be pivoted between a first position in which the drinking nozzle rests against the main closure body and a second position in which the drinking nozzle is distant from the main closure body, a tubular body for piercing the membrane which co-operates with the drinking nozzle in such a way that the membrane is pierced when the drinking nozzle is pivoted, thus causing a connection to be made between the opening in the drinking nozzle and the interior of the container, the drinking nozzle extending outwards beyond the tubular body, the tubular body having at its top end an opening for supplying air to the container when drinking and having at its bottom end a cutting edge, the tubular body being arranged on the main closure body to be pivotable with the drinking nozzle in such a way that, when the drinking nozzle is pivoted, the membrane is pierced by the cutting edge of the tubular body, thus causing a connection to be made between the interior of the container and both the drinking opening and the opening for supplying air.
