Description

technical field [0001] The invention relates to the technical field of hanging bottle preforms, and more specifically relates to a spiral-shaped rotatable hanging ring preform which is convenient for production. Background technique [0002] At present, plastic hanging bottles have gradually replaced traditional glass hanging bottles. Due to the particularity of drug use of large infusion products, PP soft bags, upright soft bags, plastic bottles and other plastic infusion soft packaging for plastic containers need to be provided with a ring at the bottom of the container. In order to facilitate the hanging during clinical medicine in the hospital and there are strict requirements on the orientation of the suspension ring when hanging the medicine bag clinically. [0003] The hanging bottle of the traditional structure is hung on the hook through the ring. Due to the limited size of the hanging ring, the length of the hanging ring is relatively short when hanging the bottle,...

Problems solved by technology

[0009] In mode 1, the cleaning of lifting rings and welding fumes can easily damage the cleanliness of the clean environment in the pharmaceutical production area, resulting in non-compliance of dust particles in the clean environment, contaminating containers or pharmaceuticals

[0010] In method 2, welding the lifting ring after filling or after sterilization is not only inefficient, but unqualified welding also causes waste of medicines and there is a risk of leakage due to improper welding

[0011] In the above two methods, in addition to the above problems, there is also a common problem: the number of parts increases during the production process, and the preforms and lifting rings need to be produced separately and then the plugs are welded. The operation process is complicated and the production efficiency is low.
