How to tell whether a thermos cup is true or false? Identification chart of authenticity of gourmet chef's mug

Japanese thermos thermos thermos flask is exquisite in workmanship, good in heat preservation effect, completely watertight and not heavy when filled with a glass of water. So how do you tell whether the thermos cup is true or false? Master chef's identification chart of true and false thermos cups.

Official authenticity query method

Many purchasing sellers mentioned that the Japanese version of Malaysian cooking is better than the domestic version, which is more due to the psychological function of obsequiousness and the need of purchasing publicity. In fact, it is unrealistic to expect every detail of the vacuum flask to be perfect for the vacuum flask whose price is mostly around 300 yuan, no matter whether buying foreign versions or domestic licensed cookers. Tens of thousands of industrial products, mass production, can not reach the fineness similar to seiko watch and handmade big-name bags. After all, in Macau, Japan and other countries, 100 RMB can buy a gourmet thermos cup.

For the anti-counterfeiting query method of the serial number of domestic gourmet thermos cups, as shown below, after scraping off the anti-counterfeiting coating, you can query the authenticity through the webpage /security.php or dial 400.

Distinguish the authenticity of a gourmet's thermos cup.

1, bottle cap appearance

Authentic bottle caps are frosted outside, so don't worry about dropping them when you hold them in your hand. There are also some fake thermos cups, and there is no matte outside the bottle cap, which feels sticky and soft.

Step 2: Bottle bottom

At the bottom of the bottle, the genuine thermos thermos thermos mug not only has the qualified inspection certificate, but also has the stamped English logo, which looks neat and three-dimensional. Moreover, some fakes are easily overlooked at the bottom of the bottle, and the English logo can't be found at all. Although some high imitations can see English logo, the printing is not clear, and the engraving of 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 very wide. It is easy to see that the work inside is fine and it is convenient to put some ice cubes. The mouth of the imitation bottle is relatively thin and the material is relatively thin. In addition, the genuine bottle cap adopts silicone gasket, which has good sealing and heat preservation. But most fakes only use ordinary rubber washers. Although there is no difference in heat preservation effect in a short time, the heat preservation effect will obviously decrease after a long time of use.

4. Details

Mainly look at the bottle cap, because the design of the bottle cap is more complicated, so it is easier to distinguish. The genuine bottle cap is open, which is convenient for cleaning and will not affect the heat preservation effect. The air outlet and air return hole are also very fine. After the imitation bottle cap is removed, the work inside is rough, and there are obvious injection and melting residues at the two pores. Look carefully, there are still many scratches and traces.

Step 5 pack

In terms of packaging, the packaging box of genuine THERMOS thermos mug is hard and the surface looks angular. The packaging of fake goods may be to save costs, and the material is poor. It's easy to wrinkle when you press it with your hand, giving people a feeling of collapse when you can't stand up. Imagine how this can protect the thermos.

6. Check the packaging details of the therapist's thermos cup.

For buying children's shoes similar to Japanese thermos cups, please refer to the general methods of netizens to identify them. It is easier to copy the packaging carton and instructions. Many imitation cups can be said to be no worse than the real ones, but there are still some imitations that are unwilling to invest in the cost. As shown in the circle below, due to cheap printing, the instructions of the fake cooker actually seem to be scratched by ink.

7. Check the appearance details of the thermos cup.

Making thermos cups in batches needs corresponding molds just like making pots, pans and pots, and the well-matched molds involve high mold opening cost, so fake thermos cups can't be imitated by 100% in many details. The integrated manufacturing process of the thermos cup can't be completed by a small workshop, so as shown in the following figure, there is an obvious base at the bottom of the fake cup, which is a serious injury to many fakes.

In addition, for example, the gloss and thickness of metallic paint on the surface of the cup, there is a difference between true and false cookers, but these need genuine products to compare. As shown in the following figure, compared with the bottom label of genuine thermos cup, the label of fake cup is crooked, while the label of genuine thermos cup is neat, and the bottom label and brand logo are in a straight line with the brand logo on the cup body.

There are also related patented technologies, such as the lid lock switch of gourmet thermos cups, which is also a place where fakes are prone to problems. As shown in the red circle below, there should be a small bump above the buckle (the comparison in the picture), but the fake does not. There are only two obvious injection points on the back of the genuine buckle, while there are four obvious injection points on the back of the fake buckle.

8. Check the internal details of the vacuum flask.

The silica gel pad in the cover of the thermos cup has the function of sealing and heat preservation, and must meet the food hygiene standards. The silica gel pad in the fake cup cover has obvious odor, and the material source is unknown. Authentic silicone pad has only a faint taste. Comparing the authenticity of the picture below, the genuine products in the red circle have recyclable signs, but the fake products do not.

In addition, compared with the side where the inner cup mouth can be rotated and unscrewed, it can be found that the counterfeit has an obviously rough injection mouth, but the corresponding position of the genuine one does not. This kind of injection port with abrupt surface is usually polished off, which also reflects the gap in the manufacturing process of fake molds.

Basic knowledge of distinguishing true from false

1. Simple identification method of thermal insulation performance: pour boiling water into a thermos cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the outer surface of the cup by hand. If the temperature of the cup is obviously increased, especially if the lower part of the cup is heated, it means that the product has lost its vacuum degree and can't achieve good insulation effect, but the lower part of the thermos cup is always cold. Myth: Some people use their ears to determine whether there is a hissing sound, but they can't hear whether it is a vacuum.

2. Sealing performance appraisal method: After the cup is filled with water, tighten the bottle stopper or cup cover clockwise, and put the cup flat on the table, without water seepage; The screw-in and screw-out of the cup (pot) cover and the cup mouth should be flexible without gap. Fill a glass of water, turn it upside down for four or five minutes, or shake it a few times to verify whether it leaks.

3. Identification method of plastic parts: New food-grade plastic features: small smell, bright surface, no burr, long service life and difficult aging. Ordinary plastics or recycled plastics are characterized by large smell, deep color, many burrs, easy aging and easy fracture. This will not only affect the service life, but also affect the hygiene of drinking water.

4. Simple capacity identification method: the depth of the inner tank is basically consistent with the height of the outer shell, and the capacity (phase difference 16- 18mm) is in line with the nominal value. In order to cut corners and make up for the weight of missing materials, some domestic brands add sand and cement blocks to the cups. Myth: The cup weight is not necessarily good.

5. Simple identification method of stainless steel material: There are many specifications of stainless steel material, among which 18/8 means that this stainless steel material contains 18% chromium and 8% nickel. The materials that meet this standard are green products that meet the national food-grade standards, and the products are rust-proof and corrosion-resistant. Ordinary stainless steel cups are pale or dark in color. If it is soaked in salt water with the concentration of 1% for 24 hours, it will produce rust spots, and some elements contained in it will exceed the standard, which will directly endanger human health.

6. Identification method of cup appearance: See whether the surface polishing of inner container and outer container is uniform and consistent, and whether there are bumps and scratches; Second, see if the welding of the mouth is smooth and consistent, which is related to whether you feel comfortable when drinking water; Third, check whether the internal seal is tight and whether the plug and the cup match; Look at the mouth of the cup, the rounder the better.

7. Check the labels of cups and other accessories: see if the product name, capacity, caliber, manufacturer's name and address, adopted standard number, usage method and precautions in use are indicated. Japan is a country that attaches importance to quality, and will clearly indicate the performance of products in strict accordance with the requirements of relevant standards.
