Combined cover for flexible infusion package

The utility model discloses a combined cover for a flexible infusion package, which belongs to the technical field of medical devices. The combined cover comprises an inner cover and an outer cover with a pull ring, wherein threads are arranged on the inner wall of the inner cover, a rubber plug is arranged between the outer cover and the inner cover; and one or more infusion holes are arranged on the rubber plug. As the combined cover comprises the inner cover and the outer cover with the pull ring; the threads are arranged on the inner wall of the inner cover, the rubber plug is arranged between the outer cover and the inner cover so that a liquid medicine can be isolated from the rubber plug so as to prevent the rubber plug from contacting the liquid medicine, thereby ensuring the quality of the liquid medicine.
