Light drinking water bottle

Abstract

The invention relates to a container for filling drinking liquid, and in particular relates to a light drinking water bottle. The light drinking water bottle comprises a drinking water bottle body, wherein the drinking water bottle body is manufactured by drawing and blowing-molding a light bottle blank, the wall thickness of the blank body of the light bottle blank is 2-3.8mm, the cross section of the blank bottle of the light bottle blank is cone-shaped, an included angle between two side edges of the cross section of the blank bottle is 55-65 degrees, the total draw ratio of the drinking water bottle body is 12-16, and the one-way draw ratio of the drinking water bottle body is 3.8-5. According to the invention, by optimizing and designing the blank body and the blank bottom of the bottle blank, the material consumption of the drinking water bottle body can be reduced, the consumption of raw materials is reduced while enough structural strength of the drinking water bottle is ensured, and the production cost is lowered.

Description

technical field [0001] The invention relates to a container for filling drinking liquid, in particular to a lightweight drinking water bottle. Background technique [0002] Existing drinking water bottles are generally made of PET materials. With the rapid development of the bottled water industry in recent years, the demand for PET materials is also increasing, which not only causes a large consumption of resources, but also drives The price of PET material keeps rising, and the production cost of a single drinking water bottle keeps increasing. In order to solve the above problems, people need to reduce the amount of PET material of a single drinking water bottle as much as possible in the production process to reduce the cost, but after reducing the amount of PET material of a single drinking water bottle, the structural strength of the drinking water bottle will be reduced. The body of the water bottle becomes soft and it is difficult to guarantee the effect of use. C...
