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

Embodiment 1

[0052] A sterile plastic preform, comprising a preform mouth 1, a preform neck 2, a preform body 3 and a preform bottom 4, the four are integrally formed by injection molding, the preform mouth 1, the preform neck 2, the preform The preform body 3 and the preform bottom 4 are integrally formed by injection molding. There is a thread 5 on the outside of the preform mouth 1, the bevel angle of the cut surface of the thread 5 is 45°, and the bevel angle of the cut surface is 10°.

[0053] Further, the preform bottom 4 is arc-shaped and connected with the preform body 3 in a straight line, and the preform body 3 passes through the preform neck 2 and the preform mouth 1 are connected in a streamlined shape; the thread 5 is a discontinuous thread 5 with a fracture, in a rising and spiraling state, the angle between the fractures is 47°, the thread height is 7.5mm, and the upper surface and the lower surface are in a straight line Transition; the radius of the preform opening 1 is 9....

Embodiment 2

[0062] The difference from Example 1 is that the ratio of the thickness of the preform body 3 to the thickness of the preform bottom 4 is 1.2:1.

Embodiment 3

[0064] The difference from Example 1 is that the ratio of the thickness of the preform body 3 to the thickness of the preform bottom 4 is 1.5:1.

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 an aseptic plastic bottle embryo. Background technique [0002] At present, the preform bottom of the preform in the market is mostly arc-shaped, and the preform body and the preform bottom have the same thickness. After blow molding, there are often plastic accumulations at the bottom of the bottle. This part of the plastic is not very useful, not only unsightly Moreover, it causes a waste of materials. In addition, if the wall thickness of this type of preform is relatively thin, the bottle will easily burst during blow molding, which will affect the appearance and use. [0003] The patent with the application number 201320332806.1 discloses a hot-fill lightweight beverage bottle mouth. Compared with ordinary bottle mouths, the overall height of the bottle mouth, thread width and wall thickness are reduced, saving materials and ensuring bottle In addition, this utility...
