What are the differences between vacuum cups and thermos cups?

In modern life, whether at home, in the office or traveling outdoors, we need a container that can maintain the temperature of our drinks for a long time. The two most common types currently on the market are vacuum cups and thermos cups. Although they both have some insulation capabilities, there are some significant differences between them. This article will detail the main differences between these two cups.

First, let’s take a look at the vacuum cup. A vacuum cup is a cup with a vacuum inside. This design can effectively prevent the transfer of heat, thereby achieving the effect of heat preservation. Vacuum cups are usually very insulating and can keep drinks hot for hours. Additionally, another advantage of vacuum cups is that they are lightweight and easy to carry. However, the disadvantage of vacuum cups is that their insulation effect is greatly affected by the outside temperature. If the outside temperature is too low, the insulation effect of the vacuum cup may be greatly reduced.

Next, let’s take a look at the thermos cup. The design principle of the thermos cup is to prevent the transfer of heat through a double-layer structure, thereby achieving the effect of heat preservation. The inner layer of the thermos cup is usually made of stainless steel or glass, and the outer layer is made of plastic or metal. This design not only effectively maintains the temperature of the drink, but also forms a thermal insulation layer on the outside of the cup to prevent heat loss. Therefore, thermos cups generally provide better insulation than vacuum cups and can maintain the temperature of beverages for several hours or even a whole day. In addition, another advantage of thermos cups is that their insulation effect is not affected by the outside temperature. Even in cold environments, thermos cups can maintain good insulation effects.

In addition to the heat preservation effect, vacuum cups and thermos cups also have some differences in other aspects. For example, vacuum cups are generally lighter and more portable than thermos cups. The thermos cup is usually more durable than the vacuum cup and is more suitable for long-term use. In addition, the appearance designs of vacuum cups and thermos cups are also different. Vacuum cups are usually simpler, while thermos cups have more colors and patterns to choose from.
