Nowadays, cold air invades, and people begin to feel the cold in winter. At this time, it will be a very pleasant thing to have a beautiful and durable thermos cup on hand, and you can drink hot tea at any time. Compared with the simple container function of the traditional glass thermos, the current thermos has become a product that is compatible with leisure, tourism and sports. Moreover, it has many advantages such as light weight, anti-breakage, convenient use, better and better heat preservation performance, and distinctive shape, etc., and it is also favored by more and more consumers and quickly became popular.
as a vacuum flask invented by Japan in the last century, has also undergone continuous renewal and technological improvement. At present, the styles and types of vacuum flasks sold on the market have made great progress, and various businesses have accelerated their creativity and launched new products one after another. For example, there are traditional thermal insulation cups and travel pots; various and colorful automobile cups that have been popular with foreign businessmen in the past two years; password cups to protect personal drinking water health, and so on. Not long ago, it won the 2010 Red Dot Design Award and IDEA Award, and the vacuum flask named "heartea" is also quite eye-catching. In addition to its simple appearance, this vacuum flask is also designed with a small LED light on the wall of the cup. It will change the color according to the different temperatures in the cup, which is convenient for users to grasp the water temperature. If it is red, it means the cup The water temperature inside is 75 to 90 degrees Celsius, so be careful not to burn your mouth.
Although it looks simple and creative, it can be regarded as a big improvement for daily necessities like thermos cups. According to a salesperson in a thermos cup store, the most popular products on the market are bullets, bachelor cups, tea cups, travel pots and other insulation series products. There are also some new products in the travel pot series. For example, there is a newly designed multifunctional one-pot double-lid travel pot with a small bowl that can be used by multiple people. The unique bottom design has two foldable stainless steel spoons inside, which is easy to use. .
The information provided by the China Cup Products Professional Committee of the Daily Sundries Industry Association shows that the current domestic thermal insulation glass manufacturers are mainly located in Guangdong, Shanghai and Zhejiang, of which Zhejiang Yongkang is the most concentrated. At present, Yongkang has more than 800 thermal insulation glass production and supporting enterprises. The average annual output will exceed hundreds of millions of products, including high, medium and low grades and specifications. Yongkang has become the country's largest production base for insulating glass. As the two major production bases of vacuum flasks in the country, the gap between Yongkang and Guangdong enterprises is also very obvious, which is mainly reflected in independent research and development capabilities and product quality. The export price of the same thermos cup produced in Yongkang is about 11 US dollars, while the export price of Guangdong production is more than 14 US dollars. In the domestic market, the same cup can be sold for 50 to 60 yuan from Yongkang and 70 to 80 yuan for Guangdong.
It is understood that at present, my country has formulated various national standards for stainless steel food containers, but since it is not mandatory, most companies in Yongkang still use their own corporate standards. According to industry insiders, with the increase in the price of raw materials and the pressure of appreciation of the renminbi, companies in the thermos cup industry in Yongkang have switched from imported materials to domestic ones, causing the quality of the entire industry to decline. In addition, some thermos cup manufacturers also use plastic parts that do not meet the sanitary standards of primary and secondary recycled materials, which also leads to a decline in product quality.
In recent years, the Yongkang vacuum flask industry has gradually begun to focus on product upgrading and self-brand formation. For example, insulation cup manufacturers such as Zhejiang Yongkang Yipinshi Cup Industry Co., Ltd. have increased scientific and technological investment, introduced advanced equipment and technical personnel, and carried out bold innovations in insulation cup styles, patterns and packaging, and successfully developed office cups and children's insulation Cups, travel pots and other products are welcomed by domestic and foreign markets. At present, there are 6 enterprises with an annual output value of more than 100 million yuan in the Yongkang vacuum flask industry. The production and sales volume of stainless steel vacuum flasks has accounted for half of the country, and more than 70% of the products are exported.
There are many varieties of stainless steel vacuum flasks currently on the market, and the prices vary greatly. For many consumers, they often spend a lot of money to buy products that are not satisfactory. How can I buy a high-quality vacuum flask? Experts suggest that the first thing to look at is the appearance of the cup. First, check whether the inner and outer bladder surfaces are uniformly polished, whether there are bruises and scratches; second, whether the mouth welding is smooth and consistent, which is related to whether you feel comfortable when drinking water; third, whether the quality of the plastic parts is Poor quality of parts will not only affect the service life, but also affect the sanitation of drinking water; fourthly, see whether the internal seal is tight. Whether the screw plug and the cup body fit properly. Whether it is easy to rotate in and out, and whether it is leaking. Look at the thermal insulation performance, this is the main technical index of the vacuum flask. In general, it is impossible to check according to the standard when purchasing, but you can check it by hand after filling it with hot water. The lower part of the cup body will heat up two minutes after the non-insulated cup is filled with hot water, while the lower part of the insulated cup is always cool.
Experts also remind consumers to avoid collisions and impacts during use to avoid damaging the cup or plastic, causing insulation failure or water leakage. Use proper force when tightening the screw plug, and do not rotate it excessively to avoid screw failure.
