How to Identify Good Thermal Bottle

Tips of purchasing

There are many kinds of stainless steel insulating cups sold on the market, and the price difference is very large. For some consumers, they do not understand the principle and often spend a lot of money to buy unsatisfactory products. How can we buy high quality vacuum insulating cups?

First of all, it depends on the appearance of the cup. See if the polishing of the inner and outer surfaces is uniform, whether there are bruises and scratches.

Second, to see whether the mouth welding is smooth and consistent, which is related to whether the feeling of drinking water together is comfortable;

Third, the quality of plastic parts is poor. Not only will it affect the service life, but also the sanitation of drinking water.

Fourth, see if the internal seal is tight. Whether the screw plug and cup body fit properly. Whether it is free to spin in and out, whether it leaks water. Fill a glass of water and put it upside down for four or five minutes or shake it forcefully for a few minutes to verify the leak. Looking at the insulation performance, this is the main technical index of the insulation cup. Generally, it is impossible to check according to the standard when purchasing, but it can be checked by hand after filling the hot water. The lower part of the cup will be hot after two minutes of filling the non-insulated cup with hot water, while the lower part of the insulated cup will always be cool.

Specifically, there are several methods as follows:

1. Simple identification method of vacuum insulation performance: Pour boiling water into the insulating cup, tighten the bottle stopper clockwise or the cup cover for 2-3 minutes, then touch the outside surface of the cup body with your hand. If there is obvious warm phenomenon in the cup body, it means that the product has lost its vacuum and can not achieve good insulation effect.

2. Sealing performance identification method: after adding water to the cup, tighten the bottle stopper and cap clockwise, place the cup flat on the table, there should be no water leakage; the cup cap and the cup mouth should be flexible, no gap.

3. Identification of plastic parts: The characteristics of food-grade new plastics are small odor, bright surface, no burr, long service life and not easy to aging. Ordinary plastics or recycled plastics are characterized by large odor, dark color, many burrs, and easy aging and fracture of plastics.

4. Simple capacity identification method: the depth of the inner gallbladder is basically the same as the height of the outer shell, (16-18MM difference) and the capacity is consistent with the nominal value. Some of the poorer insulating cups add sand and cement blocks to make up for the missing weight. Myth: Heavy cups (pots) are not necessarily good.

5. Simple identification method of stainless steel material: stainless steel material specifications are many, of which 18/8 indicates that the stainless steel material composition contains 18% chromium and 8% nickel. Material that meets this standard meets the national food-grade standard is green environmental protection products, products are rust-proof and corrosion-resistant. The color of ordinary stainless steel cup is white and dark. If it is soaked in 1% salt water for 24 hours, rust spots will appear. Some elements in the cup exceed the standard, which directly endangers human health.

Maintenance method

In the use process, collision and impact should be avoided to avoid damaging the cup or plastic, resulting in thermal insulation failure or leakage. When tightening the screw plug, the force should be appropriate, and do not rotate excessively, so as to avoid the failure of the screw. When drinking coffee, tea or drinks regularly, the inner gallbladder will discolor, which is a normal phenomenon. It can be removed with toothpaste toothbrush.

Four Ways to Identify the Quality of Thermal Cup

In the market, the quality of insulating cups varies from good to bad. How to identify ordinary consumers? Industry insiders suggest that we should focus on the insulation performance of its inner liner structure, the sealing degree of the cup cap and bottle body, whether the material releases harmful substances, etc. Specifically, we can identify them by four methods.

This is the main technical index of insulating cup. After filling with boiling water, tighten the bottle stopper or cup cap clockwise and touch the outer and lower parts of the cup body with hands after 2-3 minutes. If there is obvious warm phenomenon on the cup body and the upper part of the cup body, it shows that the inner gallbladder has lost its vacuum and can not achieve good insulating effect.

The second trick is to identify the sealing performance by filling a glass of water and inverting it for four or five minutes, tightening the lid, placing the cup flat on the table, or throwing it forcefully for several times. If there is no leakage, the sealing performance is good. In addition, it is necessary to see whether the cap and the mouth of the cup are flexible and whether there is a gap.

Environmentally friendly identification of plastic accessories is also a matter of concern. It can be identified by smell. If the cup is made of food-grade plastics, it will have smaller odor, bright surface, no burr, long service life and not easy to aging. Ordinary plastics or recycled plastics will have large odor, dark color, more burrs and easy to aging and fracture.

Collapse Editing Instructions for Use of this Paragraph

1. Before the new product is used, it must be ironed several times with boiled water (or with some food detergent) for high temperature disinfection. (2) Before use, preheat (or pre-cool) with boiling water (or cold water) for 5-10 minutes in order to improve the insulation effect.

3. Please fill up the water in a hurry so as not to overflow the scald when tightening the cap.

4. Drink slowly when you are hot to avoid scalding.

5. Carbonated drinks such as milk, milk products and fruit juice should not be kept for a long time.

6. After drinking, please tighten the cup cover to ensure hygiene and cleanliness.

7. Soft cloth and edible detergent diluted by warm water should be used for cleaning. Do not use alkaline bleaching agent metal vegetable melon cloth, chemical cloth, etc.

8. The inner side of stainless steel cup sometimes produces some red rust spots due to the influence of iron and other substances in the contents. It can be soaked in diluted vinegar with warm water for 30 minutes and then cleaned thoroughly.

9. In order to prevent odor or stain, and can be used for a long time. After use, please clean and dry it thoroughly.
