With the innovation of Thermos Flask's products and technology, a special manufacturing process which can avoid the damage of the cup gall bladder and air leakage--no-tail vacuum technology was born.

What is the vacuum cup without tail, first of all, we first understand the structure of the traditional thermos.

The traditional Thermos cup is usually made of two layers of glass or stainless steel, the middle vacuum, to insulate heat transfer, so the bottom of the cup gall bladder has a suction tail, this suction tail is easy to touch bad or gas leakage, therefore, no tail vacuum technology was born, no tail vacuum technology is the use of special welding technology, so there is no sharp end of the suction tail, to avoid a bad suction tail and damage cup gall bladder or due to air leakage and affect the use of the effect of the thermos.

At present the market on the sale of stainless steel vacuum mug, due to the vacuum of the technical means of different, generally divided into: a tail vacuum and no tail vacuum two kinds.

The tail vacuum is a traditional technology, and no tail vacuum is one of the most advanced technology at home and abroad. The difference between the stainless steel vacuum mug and the vacuum Thermos Cup produced by the technology without tail vacuum is mainly embodied in the following points:

1, the technology is different: "has the tail vacuum" to be called the tube type vacuum is the traditional vacuum craft, uses is "The Pressure seal technology", this technical measure in the microscopic cannot completely guarantee airtight; No tail vacuum "is the most advanced vacuum technology at home and abroad, that is, the vacuum flask in the environment, the computer to control the completion of pumping, sealing, cooling process, the use of" melt sealing technology "can ensure a long-term no air leakage.

2, the equipment is different: "No tail vacuum" cup of equipment is a large equipment, high degree of automation, high level of product quality, the cost is also expensive, and management and use of technology complex, not easy to master, the single product power consumption is higher than "there is a vacuum" several times, so at present, only a few enterprises fully grasp and use this technology. But this kind of craft technology product quality is high, the performance is better, it will become the vacuum flask technology which the mainstream of the manufacturing industry.

3., the vacuum is higher, the heat preservation time is longer: because the vacuum Thermos Cup is in the near 1000 ℃ condition vacuum and the seal welds, at this time its vacuum degree and has the tail vacuum is same, when the product returns to the room temperature, its vacuum degree will be much higher than "has the tail vacuum".

4, effective Capacity: because there is no "tail vacuum" like the mouse tail, do not need to set a "hidden tail room", so effective space. Compared with the product of "tail vacuum", the effective space inside the vacuum flask is much larger.
