How to choose a thermos cup? What are the techniques to make a good cup stand out? How to choose a thermos cup? What are the tips for choosing a thermos cup? What should I pay attention to when purchasing a thermos cup? Teach you how to select high-quality insulated cups! Through the online shopping platform of Taobao alone, it is not difficult to find that the prices of stainless steel insulated cups sold in major Taobao stores vary greatly, ranging from 10 yuan insulated cups to outdoor gift insulated cups priced at over 300 yuan. From the evaluation details of various online purchases, the quality evaluation varies greatly. To choose a truly healthy thermos cup, you can distinguish its authenticity from the following points.
1. Look at the anti-counterfeiting label. Firstly, check if the label or instruction manual of the stainless steel insulated cup has the manufacturer's anti-counterfeiting label.
2. Look at the appearance. From the appearance of the vacuum insulated cup, the appearance mainly depends on whether the polishing of the inner and outer surfaces is uniform and consistent, and whether there are any bumps, scratches or burrs; Secondly, check whether the welding at the mouth is smooth and consistent, which is related to whether the feeling when drinking water is comfortable; Check if the internal seal is tight and if the plug matches the cup body; Finally, look at the rim of the cup four times. The rounder the better, as immature techniques may result in a lack of roundness.
3. Check the sealing. When checking if it is sealed, first twist off the cup lid to see if it fits perfectly with the cup body. Then add hot water (preferably hot water) to the cup and invert it for two to three minutes to see if there is any water seeping out.
4. Thermal insulation testing. Because the vacuum insulated cup uses vacuum insulation technology, it can prevent heat from transferring to the outside under vacuum conditions, thereby achieving insulation effect. So to test the insulation effect of a vacuum insulated cup, simply pour 100 degree hot water into the cup, and after two or three minutes, touch each part of the vacuum insulated cup with your hand to see if it is hot. If any part heats up, the temperature will be lost from that place. It is normal for there to be slight heating in areas like the mouth of a cup.
5. Identify the plastic material. A high-quality stainless steel vacuum insulated cup uses food grade plastic, which has a low odor, a shiny surface, no burrs, a long service life, and is not easily aged. Counterfeit and inferior thermos cups are usually made of ordinary plastic or recycled plastic, which have the characteristics of strong odor, dark color, many burrs, easy aging and breakage of plastic, and will also emit a foul odor after a long time. This not only shortens the lifespan of vacuum insulated cups, but also poses a threat to our physical health.
6. Detect capacity. Because stainless steel vacuum insulated cups are double layered, there may be some discrepancies between the actual capacity of the cups and what we see. First, check if there is not much difference between the depth of the inner liner and the height of the outer layer of the vacuum insulated cup (usually 18-22mm). Many small factories often focus on materials to reduce costs, which may affect the capacity of the vacuum insulated cup.
7. Identify the stainless steel material. The high-quality stainless steel insulated cup is made of 304 stainless steel material, which meets the national food grade standards and is a green and environmentally friendly product. This material is strong, hard, not easily deformed, has a bright color, and will not rust; Counterfeit and inferior thermos cups are mostly made of ordinary 201 stainless steel material, which has excessive manganese content and low chromium and nickel content. It is not only prone to deformation and rusting, but also has a white or dark color. If soaked in 1% salt water for 24 hours, rust spots will appear, and some of the elements contained in it exceed the standard, directly endangering human health.
8. Baking process. High quality stainless steel insulated cups use pearl baking paint technology. The biggest advantage of baking paint technology is that its color is brighter, more durable and beautiful, less prone to smudging, less prone to paint peeling, and never fades; Counterfeit thermos cups often use spray painting technology, which results in a dull color and a thin and fragile paint layer. After a period of use, they will peel off like fish scales, making them prone to smudging and affecting their appearance.
