How to design a vacuum water bottle that can be produced? How to design a vacuum insulated stainless steel water bottle with excellent heat insulation performance, durability and fashion? This is a huge challenge faced by many designers.


The double-wall stainless steel vacuum insulated water bottle is different from the single-wall stainless steel water bottle. The design is more difficult due to the existence of a vacuum layer between the inner wall and the outer wall.


Recommendations for designing vacuum flasks


1. Pay attention to the distance between the inner and outer walls of the vacuum flask

The distance between the inner wall and the outer wall is usually 3mm, with a minimum of 2mm. There must be a vacuum layer with enough space to achieve the insulation effect.


2. Pay attention to the thickness of the stainless steel inner and outer walls of the vacuum flask

When the diameter of the vacuum flask is less than 70mm, stainless steel with a thickness of 0.4mm is usually used; for vacuum flask with a diameter greater than 70mm, stainless steel with a thickness of 0.5mm, 0.6mm or 0.7mm is used according to actual needs. The thicker the stainless steel, the more durable it is, but the higher the cost.


3. Selection of the metal material of the vacuum flask

The material of the vacuum flask is mostly 18/8 stainless steel (SUS304 stainless steel) and 201 stainless steel. Because 201 stainless steel is harmful to the human body, 201 stainless steel cannot be used for the inner wall of vacuum flask. Water bottles made of 201 stainless steel cannot pass the FDA test. For the thermal insulation container used for medical equipment items, or the thermal insulation container related to medical treatment, it needs to be made of 316 stainless steel.


4. Choose the plastic material of the lid/cap

Most of the cap materials are PP, Tritan and AS, and none of them contain BPA.
