3 Types to Choose A Vacuum Insulated Bottle

How big a insulated bottle should I buy?

Choosing the right size is the first step. Choosing the right insulated bottle for your needs can avoid carrying an overweight/oversized bottle, and it can meet your daily drinking needs. As small as 8 ounces, roughly 64 ounces, or larger, insulated bottles come in a variety of capacity sizes. 12-ounce bottle can hold almost a can of soda, and 16-ounce bottle is the choice of most people. If you need to use it outdoors or in sports, then you can choose a larger capacity, 64-ounce bottle can hold about 2 liters of drinks.

Which is the best material for a vacuum insulated bottle?

The inner liner of the insulated bottle is particularly important as it comes into direct contact with the drinks and must be food grade. Secondly, it also needs to be corrosion resistant and easy to clean. The most commonly used materials are 304 grade stainless steel and 316 grade stainless steel, which are corrosion resistant, recyclable and environmentally friendly, usually stamped on the bottom of the bottle or marked on the box. 316 stainless steel is more resistant to corrosion, but more expensive. If you regularly make drinks (milk, coffee, etc.) in the bottle, 316 stainless steel is recommended. As for tea, the corrosion of stainless steel is relatively small, so whether it is tea or fruit tea, choosing 304 stainless steel is enough.

It is important to note that the insulated bottle is usually double-walled, and the stainless steel level of the liner and shell may not be the same. Some insulation bottles are made of 304, but the shell is made of 204. Choose insulation bottles to ensure that the inner liner is made of food-grade stainless steel, and the shell is based on your budget and preferences.

It is also important to choose a BPA-free material for the lid of the insulated bottle to ensure the health and safety of the drink. It is important to note that the silicone gasket inside the lid should also be chosen to be food-grade silicone.

Choose a durable, non-scratchy casing for your insulated bottle. If you need to use it outdoors, choose one that is lightweight and non-slip. If you use it for office use, then it is best to use a non-slip material for the bottom.

How do a vacuum insulated bottle work?

Originally designed for food containers, vacuum insulation eliminates temperature variations by creating an airless space between the stainless steel inner and outer walls, thus maintaining the proper temperature of the beverage and preventing the outer walls from heating or sweating.

There are three ways of heat transmission: Radiation, Convection, Conduction. The structure of the vacuum insulated bottle perfectly prevents all three types of heat transfer. The silver-white surface inside the insulated bottle can reflect the radiation of the hot water, the vacuum layer between the double-layer stainless steel walls can block the heat transfer, and the bottle cap that is not easy to transfer heat can prevent the heat convection.

For stainless steel insulated bottle, double vacuum insulation is the best option. Looking into the thermos from top to bottom, you will see two layers of steel connected at the top and separated by an empty space in between.

Finally, the current insulation bottle on the market in a variety of shapes, in determining the quality of the chosen insulation bottle, choose their favourite insulation bottle shape, will greatly improve the daily use of insulation cup.
