Rotatable hanging ring bottle blank convenient to be produced

Abstract

The invention discloses a rotatable hanging ring bottle blank convenient to be produced, and belongs to the technical field of bottle blanks of infusion bottles. The bottle blank comprises a cylindrical blank body integrally formed, wherein a cavity is formed in the blank body, one end of the blank body is provided with an opening part which leads to the cavity, and the other end of the blank bodyis a closed end; the side, outside the cavity, of the closed end is connected with a pouring column, and the pouring column and a hollow cone body are coaxially arranged; a hanging ring is connectedto the pouring column, the hanging ring comprises an outer ring, a connecting rib key, an inner ring and a foldable orientation groove, the outer ring is connected with the connecting rib key throughthe foldable direction groove; the inner ring is in a circular ring shape and is composed of an outer ring of the inner ring, an inner ring of the inner ring and pouring ribs, one end of each pouringrib is arranged on the side wall of the inner ring of the inner ring, and the other end of the pouring rib is connected with the pouring column; a conical limiting cap is arranged at the tail end of the pouring column, and the diameter of the limiting cap is larger than that of the inner ring of the inner ring; the blank body is integrally formed with the pouring column, the pouring ribs, the inner ring, the connecting rib key and the outer ring correspondingly.

Description

technical field [0001] The invention relates to the technical field of hanging bottle preforms, and more specifically relates to a 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] In the actual production process, most infusion companies adopt the following two methods for the production of the rotatable lifting ring at the bottom of the container: [0004] 1. A gate is designed on the embryo bod...

Problems solved by technology

[0006] 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

[0007] 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

[0008] 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.
