The present invention relates to a sealing cap for an infusion pack, and more particularly, to facilitate the administration of a chemical solution by allowing the chemical liquid filled in the fluid pack to flow smoothly into the sealing cap, and to block the contact of the rubber before the chemical liquid to administer the chemical liquid. It relates to a sealing cap for an infusion pack to increase the safety of patients receiving.

In general, the sap pack refers to a plastic pack stored in a saline solution, nutrients, glucose and other sap and kept blocked from the outside, mainly used in bottles, clinics.

The lower part of the infusion pack is equipped with a sealing cap, and by inserting a needle or the like before the rubber is mounted in the center of the sealing cap, the contents of the infusion pack can be administered to the human body. That is, in order to maintain the sealed state of the contents of the sap pack and to administer to the human body, a sealing cap for inserting a needle or the like is necessary.

1 is a view showing an example of a conventional sealing cap known as the Korean Utility Model Registration No. 20-0308933 (name: sealing cap for the sap pack), the main body (1) and the sealing member (2) and It consists of a cover member (3).

In other words, the main body 1 is inserted into and connected to the inlet of the infusion pack, and the sealing member 2 made of rubber in the body 1 to prevent inflow of external air into the infusion pack or leakage of the infusion from the infusion pack 2. Is placed in the insert. In addition, the cover member 3 is surrounded by injection molding at one end of the main body 1 so that the sealing member 2 is not separated from the main body 1.

That is, the sealing member 2 is inserted into the center of the main body 1, and the cover member 3 is molded to cover the sealing member 2 and a part of the main body 1, thereby forming the main body 1 of the infusion pack. It can be mounted in a sealed state in the inlet.

However, the conventional sealing caps including the sealing cap for the conventional sap pack is connected to the lower end of the body using a soft tube when fitted in the sap pack, the sealing cap for the conventional sap pack is very close to the bottom of the body By molding into a small round shape, the lower end of the body is caught around the tube. Therefore, there is a closed end that causes breakage and deformation of the tube and mass production of a large number of defective products.

In addition, the conventional sealing caps including the sealing cap for the conventional sap packs were manufactured using a polycarbonate (PC), the polycarbonate has the advantage of being transparent and hard, but the injection conditions during injection It was difficult and the flow of resin was not good, there was a problem of high product defect rate.

On the other hand, Figure 2 shows an example of another sealing cap known as domestic registered utility model publication No. 20-0359666 (name: infusion sealing tip for infusion pack), the integrated tip is the lower body ( The separation preventing boss 11, the pressing boss 12 and the peeling preventing boss 13 are formed in 10, and the inner projection 21 and the through-hole 22 are formed in the sealing rubber radio 20. And, it is a structure for injection molding the upper end cap 30 having an annular projection 32 on the upper end of the lower body (10).

However, the conventional one-piece tip for other infusion packs also had a drawback in which the above-mentioned conventional problems are derived as they are, and in addition to this, there were disadvantages that further caused other problems.

That is, the other conventional one-piece tip for the sap pack is characterized in that the sealing rubber radio is protruded to the upper end of the lower body, there is a problem that the assembly of the lower body and the sealing rubber is unstable, in particular due to this problem the top cap Due to the vibration of the lower body during the movement of the lower body for the injection of the occurrence of the phenomenon that the detached or flipped from the lower body frequently occurs a closed end to produce a lot of defective products.

In addition, the integrated tip assembled through the above-described method has a problem that the assembly of the sealing rubber is unstable, so that the risk of leakage of the chemical liquid filled in the sap pack is greatly reduced, thereby greatly reducing the reliability of the product.

Accompanying drawings Figure 3 is for the patent application No. 0725653 "seal pack sealing cap" patented by the present applicant to solve the problems as described above, when described below the rubber field 120 to the top of the body 110 Inserted into the departure prevention portion 111 protruding in the circumference, the space portion (circumference between the seating portion 113 and the departure prevention portion 111 in the center of the body 110, the rubber seat 120 is seated ( 112 is formed in a hollow state, and forms a chamfered outer periphery of the insertion portion 115 of the bottom of the body (110).
