At present, plastic infusion bottles gradually replace traditional glass infusion bottles, and because of the special medication of large infusion products, plastic infusion soft packages such as PP soft bags, upright soft bags and plastic bottles of plastic containers are all required to be provided with a ring at the bottom of the container so as to facilitate hanging in clinical medication of hospitals and have strict requirements on the direction of hanging rings in clinical medicine hanging bags.
In the actual production process, most large transfusion enterprises adopt the following two modes for producing the rotatable hanging ring at the bottom of the container:
1. designing a pouring gate on the blank body, manufacturing a bottle blank with the pouring gate through injection molding equipment, sleeving the manufactured lifting ring on the pouring gate by manpower or equipment before heating the bottle manufacturing equipment, and then blowing the bottle blank into a bottle after welding a plug;
2. designing a pouring gate on the blank body, manufacturing a bottle blank with the pouring gate through injection molding equipment, stretching and blowing the bottle blank into a bottle through bottle manufacturing equipment, sleeving a lifting ring on the pouring gate through manual or other equipment after filling or sterilization, and welding a plug for molding.

When the invention is produced by injection molding, firstly, polypropylene or polyethylene granules are plasticized by an injection molding device heating device, fluid colloid is injected by an anti-drop cap 5 through an extrusion device, the colloid is poured into a blank body 1 and a pouring gate post 2 in sequence through a mold runner, when the pouring gate post 2 is poured, the colloid also respectively finishes pouring of an outer ring 3, a first reinforcing part 7 and a connecting strip 4 along the runner of a pouring rib of an inner ring 6 of an inner lifting ring in the mold, finally, the colloid respectively finishes pouring of an outer ring of the inner ring 6, an inner ring of the inner ring 6 and the pouring rib along the pouring rib, and finally, the colloid finishes the whole glue injection process after pouring the anti-drop cap 5, and finally, the integrally formed bottle blank is obtained after cooling and forming. After the integrally formed bottle blank is formed, the pouring rib 10 between the inner ring 6 and the pouring post 2 is only required to be torn off by hands, tools or dies, so that the hanging ring can be rotatably connected to the blank body 1.
When the bottle blank manufactured by the method of the invention is blown into a hanging bottle and filled with liquid, the weight is increased, the stress between the connecting strip 4 and the outer ring 3 is larger when the hanging bottle is hung on the hanging frame through the outer ring 3, and in order to ensure the firmness of the hanging bottle when the hanging bottle is hung vertically or rotated, one end of the connecting strip 4 is provided with a first reinforcing part 7 with a strip-shaped cross section, and in particular, in the embodiment, a round angle can be formed between the first reinforcing part 7 and the outer ring 3.
As shown in figure 2, a connecting strip 4 which is spirally and rotationally connected is arranged between the hanging ring and the pouring gate column 2 on the blank body 1, wherein the connecting strip 4 is fixedly connected with the outer ring 3, and the bottle blank is convenient to fix in use after being blown into a hanging bottle in order to ensure the strength. The connecting strip 4 and the pouring column 2 are matched through the inner ring 6 and the pouring column 2 to form a hole shaft structure, and the connecting strip 4 is limited on the pouring column 2 through the anti-drop cap 5, so that bottle blanks or hanging bottles made of bottle blanks can rotate on the connecting strip 4 of the hanging ring through the pouring column 2. The hanging ring and the hanging bottle can rotate, so that the problem that when a patient is treated and the transfusion process is moved, the hanging ring is inconvenient to hang medicines due to incorrect welding direction of the hanging ring, and the transfusion tube is wound and knotted to cause insufficient medicine feeding and blood return of the patient due to the fact that the transfusion tube cannot rotate in the transfusion process is solved. Also is convenient for the patient to turn over, change the position of the lower bed and the like during transfusion. The connecting strip 4 adopts the spiral type to enable the hanging bottle to be changed into a similar straight line under the action of the gravity of the hanging bottle when the hanging bottle is used, the length of the hanging bottle after the hanging ring is increased under the condition that the outer diameter of the hanging ring is not increased, the hanging bottle is convenient to hang on an infusion support through the hanging ring, the upright degree of the hanging bottle manufactured by the bottle blank during hanging is improved, and a user is convenient to hang and take the hanging bottle.
Example 2:
the present embodiment is further optimized based on embodiment 1, and the improvement compared with embodiment 1 is mainly described in this embodiment, and the same point is not repeated, in this embodiment, the blank 1 and the lifting ring are integrally formed, but the blank 1 and the lifting ring are formed into a cavity by two dies, after the whole colloid pouring is completed, the blank 1 is maintained in pressure, cooled and formed according to the injection molding process, the die clamping neck of the blank 1 is still, the outer ring 3 and the connecting strip 4 of the lifting ring are clamped by the die clamping lifting ring of the lifting ring part and are moved backwards for 1-2mm, and the pouring rib between the inner ring 6 of the lifting ring and the pouring post 2 is broken in the moving process, so that the inner ring 6 of the lifting ring can rotate around the pouring post 2 to complete the rotatable process of the lifting ring. At the same time, the mold clamping part of the hanging ring part is opened. When the clamping part of the mould of the lifting ring part is opened, the ejection mechanism of the mould of the part of the blank 1 ejects the formed rotatable blank 1 of the lifting ring out of the mould to complete the whole injection molding process. Finally, the preparation: the spiral hanging ring formed by integrally forming the embryo ring can rotate the bottle embryo. The production efficiency is further improved, and the production method provided by the invention has the advantages of high production efficiency and good product quality, and the casting rib 10 is brittle fracture and has no adverse phenomena such as burrs, wiredrawing and the like.
The method provided by the invention is simplified in terms of production flow, improves production efficiency, does not need to weld the plug (namely the anti-drop cap 5 in the invention), eliminates workshop environment pollution caused by welding the plug, eliminates risk of pollution to the bottle body or medicines, and is beneficial to guaranteeing product quality.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
