What is the difference between the double-layer bottom structure and the triple-layer bottom structure of a stainless steel thermos?

Hello everyone, "Dong Dong Talk Cup" is here. Recently, during business dealings, I have encountered a customer who has his own obsession with the structure of the bottom of a thermos cup. Today, I will talk to you about why some stainless steel thermos cups have double-layer bottoms and some have three-layer bottoms? http://www.zhanyict.com/en/ProductsDetail-VB-10445.htmlDoes the different number of layers of the bottom affect the function of the thermos cup?

The difference between double-layer bottom and triple-layer bottom of stainless steel thermos cup is still determined by product structure design. Some water cups cannot meet the requirements of double-layer bottom due to capacity and shape, so triple-layer bottom design is adopted; some products do not need triple-layer bottom, after all, adding a layer of bottom will increase not only material cost but also production cost. http://www.zhanyict.com/en/ProductsDetail-VB-10445.htmlHowever, considering that the vacuum tail at the bottom of double-layer bottom will affect the beauty of appearance, an additional layer of bottom is added to cover it. This is also called tail and no tail in the industry.

As for the method of using vacuum technology to achieve heat preservation, the three-layer bottom product is not more heat-insulating than the double-layer bottom product, but it does extend the heat preservation period of the thermos. http://www.zhanyict.com/en/ProductsDetail-VB-10445.htmlIf the bottom of the double-layer bottom thermos is not covered with a gasket made of silicone or other materials, the vacuum position will be directly exposed. Bumps during use may cause the glass beads that block the vacuum hole to fall off, thus destroying the vacuum effect.

Some thermos cups do not use the vacuum evacuation process, but are filled with insulation materials for insulation. In this way, the insulation effect of the triple bottom is indeed better than that of the double bottom. http://www.zhanyict.com/en/ProductsDetail-VB-10445.htmlThis reinforcement layer can further reduce the loss of heat energy through the bottom and provide a longer insulation effect.

In terms of design structure, in addition to the different number of bottom layers, stainless steel thermos cups may also have innovations in the cup lid and cup mouth design. For example, some thermos cups use a rotating plug-in sealing lid, which can lock in heat more effectively; the factory where the editor works has developed a thermos cup for a customer. http://www.zhanyict.com/en/ProductsDetail-VB-10445.htmlThe cup body has a window, and the window position is blocked by tritan material to facilitate users to observe the actual volume of the drink in the cup. Although the window position is blocked by double-layer material, it seems that it should be more heat-insulating in principle, but in fact it is just the opposite. This case is quite special. Friends who need to know more can send a private message to the editor.

These different designs do have different insulation effects, but in actual production, there are many factors that affect the insulation effect of water cups. http://www.zhanyict.com/en/ProductsDetail-VB-10445.htmlIn comparison, the difference between the double-layer bottom and the triple-layer bottom does not seem to be so prominent and important in affecting the insulation effect of the thermos cup.
