Preparation process of large infusion container based on integration of injection, blowing, filling and sealing

Abstract

The invention discloses a preparation process of a large infusion container based on injection-blowing-filling-sealing integration. The preparation process comprises the following steps: step 1, melting granules and carrying out blow molding to form a blank body; 2, the manufactured blank is transferred to a container forming mechanism; 3, the blank body is subjected to blow molding to form a container; and step 4, cleaning the container and completing filling and sealing. The granular material is prepared into a blank body through the blank body forming mechanism, the blank body is cooled by the out-of-mold temperature accurate control mechanism, so that the molecular intergranular rearrangement of the blank body is realized, the molecular stress is reduced, and the stress is further eliminated through the waiting of the transfer area, which is an important procedure for obtaining high transparency and is also a core process different from a BFS or ASB manufacturing method.

Description

technical field [0001] The invention relates to the technical field of forming and filling horizontal large infusion plastic infusion containers, in particular to a preparation process for large infusion containers based on the integration of injection, blowing, filling and sealing. Background technique [0002] Human intravenous infusion is the most widely used and most important treatment method in clinical practice. The safety of drugs is closely related to the packaging form, material and manufacturing process. After the infusion container is soft and plasticized, it solves the problem that the glass bottle container cannot be completely sealed for infusion, especially with the launch of the new type of infusion packaging of Sichuan Kelun Pharmaceutical Co., Ltd. - the vertical polypropylene infusion bag (referred to as "standing bag") , to solve the secondary pollution generated in the infusion process and meet the special conditions of use such as airdrops. The indust...

Problems solved by technology

The disadvantage is that the light transmittance is only two-thirds of that of the two-step method, and the production efficiency has been greatly improved year-on-year. However, the two-step method is still lower than that of the two-step method. The containers made need to be transported before they can be washed, filled, Sealing and other manufacturing processes, there is still a risk of contamination in the container turnover link

[0006] The advantages of the container produced by the two-step method (injection molding - bottle blowing) are: high transparency, which can generally reach more than 95%, can realize fully sealed infusion and can realize complete self-draining, and the production efficiency and material utilization rate are higher than those of ASB and BFS. High; the disadvantage is that the infusion container is manufactured separately on two equipments, and there is a risk of contamination when the embryos collide with each other during the transfer process of the injection molded embryos
