Plastic bottle cap of infusion bottle

Abstract

The invention discloses a plastic bottle cap of an infusion bottle. The plastic bottle cap of the infusion bottle comprises an outer cover and a rubber mat; the outer cover comprises an upper cylinder and a lower cylinder; the rubber mat is clamped in the upper cylinder of the outer cover; a circle of bulges are formed on the inner wall of the upper cylinder; and a circle of grooves which are tightly matched with the bulges are formed on the outer side of the rubber mat. The plastic bottle cap of the infusion bottle is opened conveniently; the exfoliation rate of rubber mat puncture is low; astructure is simple, the plastic bottle cap of the infusion bottle is convenient to use and manufacture; manufacturing cost is reduced; and the yield of a product is increased at the same time.

Description

technical field [0001] The invention relates to the field of packaging of transfusion medicines, in particular to a combined cover matched with a plastic transfusion container. Background technique [0002] At present, large-volume injections are directly infused into human veins. Because of their rapid drug effects, they are widely used in medical treatment. Intravenous injections inevitably require a large number of infusion bottles. At present, plastic packaging materials for large-volume infusions are widely used, especially plastic composite covers. The existing combined cover is usually a pull-ring type. This pull-ring combined cover is composed of an outer cover, a rubber pad and an inner cover. The rubber pad is sandwiched between the outer cover and the inner cover. The outer cover, the rubber pad and the inner cover A combined sealing layer is formed between the three covers. The pull ring is arranged on the top of the outer cover. When the combined cover is used,...

Problems solved by technology

This kind of bottle cap has disadvantages in actual use. When the infusion needle is inserted, the debris generated when the rubber pad and the inner cover are punctured will be brought into the infusion, causing foreign matter in the infusion. These debris will even block the needle hole and cause the infusion to be interrupted. The structure of the bottle cap is complex and the product cost is high
