Japan’s thermos thermos cup is exquisite, has good thermal insulation effect, does not leak at all, and is not heavy when filled with a glass of water. So how to identify the authenticity of a Thermos thermos cup? Identification chart of the authenticity of a Thermos thermos cup.
Official authenticity check method
Many purchasing agent sellers mentioned that the Japanese version of Malaysian thermos is better than the domestic version, which is more due to the psychology of favoring foreigners and the need for purchasing agents. In fact, whether you are purchasing a foreign version or a domestically produced thermos cup, you should not look at the thermos cups with the price of around 300 yuan. Do you expect every detail of the thermos cup to be flawless? Realistic. Industrial products produced in multiple batches, often tens of thousands of pieces, cannot reach the level of precision similar to Seiko watches or handmade big-name bags. After all, in countries such as Macau and Japan, a Thermos thermos cup can be purchased for more than 100 RMB.
For the anti-counterfeiting query method of the serial number of the domestic Thermos thermos cup, as shown in the figure below, after scraping off the anti-counterfeiting coating, you can check the authenticity through the web page/security.php or dial 400.
How to identify the authenticity of Thermos thermos cups
1. Appearance of the bottle cap
The outside of the genuine bottle cap is frosted, so you don’t have to worry about it getting dirty in your hands. fall off. As for some fake Thermos thermos bottles, the outside of the bottle cap is not frosted, feels sticky to the touch, and has a soft texture.
2. Bottom of the bottle
As for the bottom of the bottle, the genuine THERMOS thermos cup not only has an inspection certificate, but also has a steel-stamped English logo, which looks neat and three-dimensional. For some fakes, it is easier to overlook the bottom of the bottle, and the English logo cannot be found at all. Although you can see the English logo on some high imitation products, the printing is not very clear and the steel seal is relatively shallow.
3. Bottle cap and bottle mouth
When you open the thermos cup, you can see that the mouth of the cup is wide, and you can easily see the fine workmanship inside, and put some ice cubes inside. It's also very convenient. The mouth of the imitation bottle is relatively thinner, and the material is relatively thinner in comparison. In addition, the genuine bottle cap uses a silicone gasket, which has better sealing and heat preservation properties. However, most fakes only use ordinary rubber gaskets. Although there is no difference in the insulation effect in a short period of time, the insulation effect will significantly decrease over time.
4. In terms of details
The main thing is to look at the bottle caps. Because the design of the bottle caps is more complicated, it is easier to distinguish. The genuine bottle cap is open, which is more convenient if you want to clean it, and it will not affect the heat preservation effect. The air outlet and air return holes are also made more precisely. After the imitation bottle cap is removed, the workmanship inside is relatively rough. There are obvious melting residues at the two pores. If you look closely, there are many scratches and imprinted impurities.
5. Packaging
In terms of packaging, the packaging box of the genuine THERMOS thermos cup is made of relatively hard material and has sharp edges on the surface. The packaging of fake products may be to save costs, but the material is relatively poor. When pressed by hand, wrinkles will easily appear, giving people a feeling of being unable to stand up. Imagine how this will affect the thermos cup. protective effect.
6. Check the packaging details of the Thermos Thermos Cup
For children’s shoes similar to the Japanese version of the Thermos Thermos Cup, here is the method of netizen Fatty to identify them. It is relatively easy to imitate packaging cartons and instructions. The packaging of many imitation cups can be said to be no worse than the real ones. However, there are still some imitations that are not willing to invest in costs and the differences are obvious. As shown in the circle in the picture below, the fake Thermos The instruction manual actually had ink scratches due to cheap printing.
7. Check the appearance details of the Thermos thermos cup
Batch production of thermos cups requires corresponding molds just like making pots and pans, and fine matching molds involve expensive mold opening. Cost, so the fake Thermos thermos cup cannot be imitated 100% in many details.
The one-piece production process of the Thermos thermos cup cannot be completed by small workshops, so as shown in the picture below, the bottom of the fake cup has an obvious base, which is a flaw in many fakes.
In addition, there are differences between genuine and fake thermos, such as the gloss and thickness of the metallic paint on the surface of the cup, but these require a genuine product for comparison to make the effect obvious. As shown in the picture below, comparing the bottom labels of real and fake THERMOS cups, the label of the fake cup is askew, while the label of the genuine Thermos cup is neatly pasted, and the bottom label, brand logo and the brand logo on the cup body are in a straight line.
The lid lock switch of the Thermos thermos cup has related patented technology, which is also where fakes are prone to problems. As shown in the red circle in the picture below, there should be a small bump on the top of the buckle (for the comparison model in the picture), but there is not in the fake one. There are only two obvious injection points on the back of the genuine buckle, while the fake one There are four obvious injection points on the back of the buckle.
8. Check the internal details of the Thermos thermos cup
The silicone pad inside the lid of the thermos cup has the function of sealing and heat preservation and must comply with food hygiene standards. The fake silicone pad inside the cup lid has an obvious odor, and the source of the material is unknown. The authentic silicone pad only has a slight smell. As shown in the comparison of authenticity and authenticity in the picture below, the genuine product in the red circle has a recycling mark, but the fake one does not.
In addition, when comparing the side of the inner cup mouth that can be rotated and unscrewed, it can be found that the fake has an obviously rough injection molding mouth, while the genuine product does not have the corresponding position. This kind of abrupt injection port on the surface should be removed by polishing under normal circumstances, which also reflects the gap in the fake mold manufacturing process.
Basic common sense in distinguishing true from false
1. Simple identification method of thermal insulation performance: Pour boiling water into the thermos cup and tighten the cork or lid clockwise for 2-3 minutes, then use your hands Touch the outer surface of the cup body. If the cup body is obviously warm, especially the lower part of the cup body, it means that the product has lost its vacuum and cannot achieve good heat preservation effect. The lower part of the insulated cup body is always cool. Misunderstanding: Some people use their ears to hear whether there is a sizzling sound to determine its thermal insulation performance. The ears cannot tell whether there is a vacuum.
2. Sealing performance identification method: After adding water to the cup, tighten the bottle stopper or cup lid clockwise, place the cup flat on the table, there should be no water seeping out; the cup (pot) lid and The cup mouth should be flexibly screwed in and out without any gaps. Fill a cup of water and hold it upside down for four or five minutes, or shake it vigorously a few times to verify whether there is water leakage.
3. How to identify plastic accessories: Features of new food-grade plastics: low odor, bright surface, no burrs, long service life and not easy to age. The characteristics of ordinary plastics or recycled plastics: strong smell, dark color, many burrs, and plastics are easy to age and break. This will not only affect the service life, but also affect drinking water hygiene.
4. Simple capacity identification method: the depth of the inner tank is basically the same as the height of the outer shell (the difference is 16-18mm). The capacity is consistent with the nominal value. Some domestic brands cut corners to make up for the missing weight of materials. , add sand and cement blocks to the cup. Myth: A heavier cup does not necessarily mean a better cup.
5. Simple identification method of stainless steel materials: There are many specifications of stainless steel materials, among which 18/8 means that the stainless steel material contains 18 chromium and 8 nickel. Materials that meet this standard meet the national food grade standards and are green and environmentally friendly products. , products are rust-proof and corrosion-resistant. Ordinary stainless steel cups are white or dark in color. If they are soaked in salt water with a concentration of 1 for 24 hours, rust spots will appear. Some of the elements they contain exceed standards and directly endanger human health.
6. How to identify the appearance of the cup: First, check whether the surface polishing of the inner and outer tanks is even and consistent, and whether there are bumps and scratches; second, check whether the mouth welding is smooth and consistent, which is related to Whether it feels comfortable when drinking water; third, check whether the internal seal is tight and whether the screw plug matches the cup body; fourth, check the mouth of the cup, the rounder the better.
