Tired of round water bottles? KingStar has developed flat 18/8 flasks with a double-wall structure. These square tumblers are sought after for their trendy look and compact design. To fully appreciate how these flat vacuum insulated cups work, let’s explore some key aspects of insulated water bottles. This article will explain the principles behind vacuum insulation and enhance your understanding of drinkware.
How Do Vacuum Insulated Flasks Work?
To begin with, water bottles are designed with a double-wall structure to achieve temperature retention. The air between the inner layer and the outer layer needs to be pumped out. This is done using a narrow tube from the bottom of the bottle. The purpose is to create a vacuum insulation layer.
The tumbler then needs to be well sealed to prevent air coming inside. Since heat can not transfer in vacuum, thermoses can keep beverages hot or cold for a significantly longer period.
Why Vacuum Insulated Vessels Usually Adopt Round Shape?
When pressure is applied, for a round bottle, the curved surface allows for uniform stress distribution. It spreads evenly across the entire surface, reducing the risk of deformation. That’s why water bottle is mostly cylindrical, enabling it withstanding huge pressure.

Why Should You Own A Square Insulated Tumbler?
1. First, a flat water bottle is the perfect companion for daily commutes. Since its shape is square, it won’t occupy extra space. This space-saving mug can easily fit in your purse or even pocket, which is ideal for daily commutes. Whether in a crowded subway or on a bus, its compact design allows you to stay hydrated on the go.
2. In addition, if you are looking for a non-mainstream product in this urban society, an innovative flat drink bottle is the perfect choice. It helps to celebrate your individuality in a world where popular culture is prevailing.
Is Making Flat Vacuum Insulated Thermoses More Difficult Than Traditional Ones?
The answer is yes! Manufacturing flat insulated flasks is much more difficult from the following perspectives:
-
Technical challenges:
As we know, stress is distributed across the surface, when pressure is applied. But for a flat or rectangular vacuum-insulated vessel, stress will concentrate at corners or edges. This will lead to potential buckling or cracking.
-
Higher cost:
Due to uneven air pressure, the inner and outer walls of flat insulated thermoses may deform over time and eventually fit together. To prevent this deformation, both walls must be significantly thicker. This results in more raw material consumption, which substantially raises the cost and the weight of the bottles.
-
Manufacturing complexity:
The manufacturing process for round bottles is mature and well-established. However, molds and equipment for flat water bottle production are far less accessible. To produce flat water jugs, it requires more time and expenses in design and testing to ensure insulation and stability.
