The invention relates to a closure cap for a container which is filled with a medical liquid and which has a mouth section sealed with a piercable membrane. The closure cap has a main closure body (1) in cap form and a drinking nozzle (4), having an opening (4a) for drinking from, which can be pivoted between a first position in which the drinking nozzle rests against the closure cap and a second position in which the drinking nozzle is distant from the closure cap. The closure cap also has means (20, 22) for piercing the membrane sealing the mouth section of the container which co-operate with the drinking nozzle in such a way that the membrane is pierced when the drinking nozzle (4) is pivoted, thus causing a connection to be made between the opening (4a) in the drinking nozzle (4) and the interior of the container. The closure cap is distinguished by the fact that, as well as the opening (4a) in the drinking nozzle (4) for drinking from, the main closure body (1) also has an opening (20a, 24) for supplying the container with air when drinking. The means (20, 22) for piercing the membrane co-operate with the drinking nozzle in such a way that, when the drinking nozzle is pivoted, a connection is made not only between the interior of the container and the opening for drinking from but also between the interior of the container and the opening for supplying air. Because both connections to the interior of the container can be made simply by pivoting the drinking nozzle, handling is simplified.本發明有關一供填注有醫療液體之容器用的封閉蓋,且該封閉蓋具有一以可刺穿隔膜密封之嘴部區段。該封閉蓋具有一主要封閉本體(1),其呈蓋子形式;與一喝飲噴嘴(4),其具有一用於由該噴嘴喝飲之出口(4a),該喝飲噴嘴可於該喝飲噴嘴停靠在該封閉蓋之第一位置、及該喝飲噴嘴係遠離該封閉蓋的第二位置之間樞轉。該封閉蓋亦具有機構(20,22),用於刺穿密封該容器之嘴部區段的隔膜,其以此一當該喝飲噴嘴(4)樞轉時刺穿該隔膜之方式與該喝飲噴嘴配合,如此在該喝飲噴嘴(4)中之出口(4a)及該容器內部之間造成一連接。該封閉蓋係藉由以下事實所區別,即除了該喝飲噴嘴(4)中用於喝飲之出口以外,該主要封閉本體(1)亦具有一入口(20a,24),用於當喝飲時以空氣供給該容器。用於刺穿該隔膜之機構(20,22)與該喝飲噴嘴(4)以下列方式配合,即當該喝飲噴嘴樞轉時,不只在該容器之內部及用於喝飲的出口之間、同時也在該容器之內部及用於供給空氣的入口之間造成一連接。因為可僅只藉由樞轉該喝飲噴嘴造成至該容器之內部的兩種連接,所以處理被簡化。1‧‧‧主要封閉本體2‧‧‧覆蓋部份3‧‧‧側緣部份4
