A sterile plastic bottle embryo

Abstract

The invention provides a sterile plastic bottle embryo, which comprises a bottle embryo opening, a bottle embryo neck, a bottle embryo body and a bottle embryo bottom. The sterile plastic bottle embryo is integrally formed through injection molding, and the purposes of saving materials, lowering the cost and preventing explosion can be achieved while airtightness of the bottle opening is ensured;antibacterial performance of the bottle embryo is high, the excellent antibacterial performance is achieved in both sunlight and shade, the antibacterial effect is lasting, stable and safe, and the application range is wide; meanwhile, the advantages of static electricity preventing, high temperature resistance, inflaming retarding, aging resistance, ultraviolet ray resistance and the like are also achieved, and the sterile plastic bottle embryo is suitable for being applied to the fields such as foods, drugs and cosmetic packages; and additionally, the bottle embryo is easy to degrade in thenatural environment and meets the requirement of environmental protection.

Description

Technical field [0001] The invention relates to the field of plastic packaging bottles, in particular to a sterile plastic preform. Background technique [0002] At present, the bottom of the preform on the market is mostly arc-shaped, and the thickness of the preform body and the bottom of the preform are the same. After blow molding, there is often plastic accumulation at the bottom of the bottle. This part of plastic is not very useful and not only unsightly. It also causes a waste of materials. In addition, if the wall thickness of the preform body of this kind of preform is too thin, the bottle will explode during blow molding, which will affect the appearance and use. [0003] The patent application number 201320332806.1 discloses a hot-filled lightweight beverage bottle mouth. Compared with ordinary bottle mouths, the overall height, thread width and wall thickness of the bottle mouth are reduced, which saves materials and guarantees the bottle The hot-filling performance o...

Problems solved by technology

However, the above-mentioned nano-antibacterial agents such as nano-titanium dioxide will only produce strong antibacterial effects when irradiated by ultraviolet rays, and their antibacterial ability is greatly affected by the environment. When the plastic bottle is stored in a shaded place, its antibacterial effect is poor. When placed in sunlight, it will affect the quality of medicines or food stored in the bottle
