The transparent bottle of moulding by the pp material manufacturing salable is in the market infused, and link is too many on manufacturing technology, need purchase the injection mold of injection machine and several specifications and the blow mold of several specifications.Production process will be made bottle base earlier, stored 5-12 hour, and then go up the professional bottle blowing machine of making after heating, use the high pressure air blow molding, finally also will make suspension ring, burn-on at afterbody, manufacture process will be finished on three machines, very loaded down with trivial details, the infusion bottle of packing medicine is handled bad on each production link, all can cause the pollution to medicine.Once input is very big, the manufacturing cost height.In addition, plastic bottle needs aerofluxus in use, easily causes secondary pollution.
The utility model content
The purpose of this utility model provides a kind of rational in infrastructure, make things convenient for mechanization bag, fill and encapsulation, effectively stop the blow molding medical bag of loading liquid seepage and leakage, it can either guarantee the pollution-free performance of bag, fill and infusion process, can realize low-cost high-speed production again, solve many defectives that existing non-PVC material transfusion bag and polypropylene infusion bottle exist.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of blow molding medical bag is characterized in that described medical bag comprises bag, and bag is provided with the filling exit and the suspension ring of protrusion, described bag, filling exit and the suspension ring structure that is formed in one.
