The invention discloses a plastic combined cover for a biological agent. The plastic combined cover comprises a top cover and a lower cover connected with the top cover in a clamped mode, the top cover comprises a top cover body with the bottom face in a plane shape, a first protrusion is arranged in the center of the top cover body, and a plurality of second protrusions connected with the top cover body are arranged in the circumferential direction of the first protrusion; and the lower cover comprises a cylinder and a connecting plate connected to one end of the cylinder, a center hole matched with the first protrusion is formed in the center of the connecting plate, a plurality of connecting holes matched with second protrusions are further formed in the connecting plate, and a plurality of clamping blocks are arranged on the inner wall of the cylinder. According to the combined cover, the design of the top cover and the lower cover is adopted, the top cover can be fixed by inserting the first protrusion of the top cover into the center hole of the lower cover, the second protrusion on the top cover is connected into the connecting hole and pressed on the butyl rubber plug of a penicillin bottle to fix the butyl rubber plug, and liquid medicine is prevented from flowing out; the sealing is convenient, and the sealing effect is good; and the two-piece combined cover design is adopted, so that the sealing cost is low.
Description
technical field [0001] The invention relates to the technical field of composite caps, in particular to plastic composite caps for biological preparations. Background technique [0002] In the prior art, butyl rubber stoppers are usually used to seal the infusion container. After the butyl rubber stopper is inserted into the container, it can be further sealed through the sealing film to ensure that the butyl rubber stopper will not be separated from the container and cause reagent loss. In addition, it can also be fixed by a combined cover Butyl stopper. [0003] Combination caps are generally composed of an outer cover, an inner cover and a lower cover, etc. The outer cover is provided with an easy-to-open part. When in use, the easy-to-open part on the outer cover needs to be opened, and the butyl rubber plug can be removed by piercing the puncture needle. reagent. In the prior art, the opening part is designed on the outer cover, and the opening part is inconvenient to...
