How to Choose a Healthy Thermos Cup

Every time arrived this season, the thermos cup of all sorts of brand and price begin to flood on market. Face the cup of full of beautiful things in eyes,lots of friends feel hard to buys oneself gratified and satisfactory. Generally, the price of a better thermos cup on the market is relatively more expensive. If the cup can't meet our basic needs, it is really not worth it. The following is a small series of carefully arranged how to correctly choose the thermos cup,for your reference, I hope to help friends in need.

1 .The principle of the thermos cup

Before we know how to choose the thermal water bottle, we say about the operation principle of vacuum cup first.Actually the thermal bottle is a vacuum containers made from ceramic or stainless steel,keep-warm top cover, seal, vacuum insulation can make in inside the liquid such as water slow cooling or keep cool,keep refreshing, So as to achieve the purpose of heat preservation.

2. Identification of the holding time of the thermos cup

Now many businesses in order to achieve their own thermos cup sales, will vigorously advocate its insulation duration, in order to meet people's demand for thermos cup. But there's actually no criterion of how long a thermos cup should keep temperature, so here's a simple test.
In the room temperature of 20℃ environment, injected ice, filled and standing state, after 6 hours, the ice does not melt, indicating that this thermos cup is relatively high quality. We add 98℃ boiled water in the same environment. After 6 hours, the water temperature is above 60℃, which is also considered as a high-quality thermos cup. So, in simple terms, the average thermos cup can keep the water warm for more than 6 hours, which is relatively high quality.
Of course, there are other factors that can affect how long the cup stays warm or cool, such as the temperature of the cup itself and the size of the water.

3. Misunderstandings and skills in the purchase of thermos cups

Most people make a lot of mistakes when it comes to thermos, and end up buying poor quality or expensive ones. But at the end of the day, we need to be practical. So I will give you a summary of a few stainless steel cup selection errors and skills.

Selection myth

The more expensive the thermos, the better

The production process of the thermos cup is not complex, vacuum insulation technology is not what high technology, even if there are differences in the price of materials, it will not sell to a very expensive price, so not necessarily the more expensive the thermos cup is the more heat preservation, we should first avoid the first mistake when choosing the thermos cup: the more expensive the more insulate!
The heavier the thermos, the better

The reason why thermos cups are so heavy is that many manufacturers add magnets or insulation to them in the process of making them. If you buy a thermos bottle that is heavier than the average thermos.Sounds like somethings are running when you shake,The vacuum cup is definitely not a vacuum, the insulation performance is not necessarily good. So it's not that the heavier the thermos, the better.
Brand thermos cup is reliable

Many friends will look for the brand to buy vacuum cup, of course, the big brands to a certain extent, have good quality guarantee of the right, but relatively speaking, the brand of the vacuum cup is also more expensive, just as we said before, the quality is not the more expensive the better, as long as the heat preservation effect is good, is also practical for itself, relatively higher cost performance, that’s the most appropriate.

Selection skills

A good thermos cup can be felt from the packaging to the appearance. We can observe the quality of the inside and outside surface of the thermos cup.

First look at the label or instruction manual of the cup.

General formal manufacturers will have written product model, name, volume, materials, production address, manufacturer, standard number, after-sales, use methods and so on. If you don't have any of those things then that's a problem.

A look at the inner and outer gallbladder surface polishing is uniform, whether there are bumps and scratches or burrs;
Second, see whether the mouth welding is smooth and consistent, which is related to the feeling of drinking water is comfortable;
Three to see whether the internal seal is tight, the screw plug and cup body match;
Four look at the mouth of the cup, the more round the better, immature technology will appear not round.
Insulation performance identification method

Pour the boiled water into the thermos cup, close the cork and leave for a few minutes, then touch the cup body with your hand. If there is obvious warm phenomenon, especially the bottom of the cup is hot, it means that the cup has lost the vacuum degree and the heat preservation performance is not good. If the cup is always cool, it means that the heat preservation effect of the cup is good.
Sealing performance identification method

This method is relatively simple, most people should know, that is to fill the glass with water, and then upside down, or vigorously shake, you can verify whether its sealing performance is good.
Plastic parts identification method

No matter what kind of insulation material, there are generally plastic accessories in it. Whether the parts used are healthy and environmental protection is a very key thing. It can be identified by smelling. If it's plain plastic, the overall shape of the thermos isn't much better.
