Four ways to identify the pros and cons of a vacuum flask

The quality of thermos cups on the market varies from good to bad. How should ordinary consumers distinguish it? Industry insiders suggest that attention should be paid to the thermal insulation performance of the inner tank structure, the degree of sealing between the cup cover and the bottle body, and whether the material releases harmful substances, etc., which can be identified by four methods.

The first step is to identify the insulation of the inner tank. This is the main technical indicator of the thermos cup. After filling it with boiling water, turn the cork or lid clockwise and touch the surface and bottom of the cup with your hands after 2 to 3 minutes. If you find the cup There is obvious warming of the body and the upper part of the cup, which means that the inner tank has lost its vacuum degree and cannot achieve a good heat preservation effect.

Trick 2 Identification of sealing performance Fill a glass of water upside down for four or five minutes, tighten the lid, place the cup flat on the table, or shake it a few times. If there is no leakage, it indicates that the sealing performance is good; Check whether the screwing between the lid and the mouth of the cup is flexible and whether there is a gap.

Three tricks to identify the environmental protection of accessories The environmental protection of plastic accessories is also a matter of concern, which can be identified by smelling. If the cup is made of food-grade plastic, it will have a small smell, a bright surface, no burrs, and a long service life that is not easy to age. ; Ordinary plastics or recycled plastics have a big smell, dark color, many burrs, and plastics are easy to age and break easily.
