Medicine bottle is a common medicine outer package. It can store both solid drugs such as tablets and liquid drugs such as potions. In the 1980s, most of the medicine bottles produced all over the world used glass as the bottle body data, and the lid used a metal unscrew lid. The major defects of this bottle are: it is not resistant to long-distance transportation, high crushing rate, and the bottle cap is not tightly closed, which is easy to cause liquid leakage, microbial pollution, mildew of the inner medicine liquid, etc. This old glass bottle has rarely been selected by pharmaceutical manufacturers in the West and China. Instead, it is a plastic bottle and pull cap made of high transparent polyester material. These newly developed medicine bottles are not only transparent, but also resistant to falling, impact and biocompatibility. Some of them are very convenient to open due to the use of lid pulling skills. Some drugs and precision medical devices are simply degenerated or damaged in a humid environment, resulting in decreased efficacy or even failure, as well as functional changes of precision medical devices. The outer packaging of such products shall be materials that can completely isolate moisture and oxygen.

Among many medical solid plastic bottles, plastic bottle is a kind of packaging container widely used. It is used in many pharmaceutical packaging. Although the quotation of injection blow molding equipment and extrusion blow molding equipment are relatively high, the production quality is very good, the degree of automation is also very high, and the production power is also very high. Most solid polyolefin plastic bottles produced and used in China use injection blow molding equipment, The domestic injection blow molding support machine has gradually reached and approached the level of relevant imported equipment, which provides very good conditions for the production of polyolefin solid plastic bottles. The molding skills of polyester solid plastic bottle mainly use the blow molding skills of injection and stretching. The raw materials of polyester are plasticized and symmetrical in the plastic barrel. In the future, the bottle blank with threaded bottle mouth is produced and processed by injection mold, and then the bottle blank mouth mold is longitudinally stretched through the stretching rod in the blow mold, The strength of the solid plastic bottle made by this method is very high, and the standardized size of the bottle mouth and thread is also relatively accurate. The standardized stability function of the solid plastic bottle body is very strong, the appearance is bright and the transparency is very good, especially for the packaging of liquid and solid drugs.
