Such cups are typically relatively heavy, typically weighing above 300g for a 450ml capacity, which is not comfortable for use by both outages and children. Although some companies or brands pay attention to the problem of heavy weight of the vacuum cup, the vacuum cup aims to manufacture a light-weight vacuum cup, for example, 316 stainless steel is selected for Jiuyang, and the weight of the cup reaches about 300g by reducing the thickness of the inner wall of the cup to 0.12 mm; the Supol cup body is made of 304 stainless steel materials, and the cup wall of the cup body is reduced to 0.12mm, so that the overall weight of the cup is reduced, and the weight of a 350ml cup is about 200 g; the THERMOS pushes out a light-weight cup, and the weight of 350ml is 225 g; however, the existing lightweight vacuum cups in the market still take stainless steel as the main cup body material, the inner wall thickness and the outer wall thickness are reduced through a special process, and although the lightweight vacuum cups are lighter than conventional vacuum cups, the density of the stainless steel is 7.7-8 g/cm³Meanwhile, the weight of the product is larger, and the product is difficult to be further thinned and lightened due to the limitation of process technology, and the lightest weight can only reach more than 200 g.

The PP has the smallest density of all synthetic resins and is 0.90-0.91 g/cm³The heat-resistant PP plastic is only stainless steel 1/8, the PP material has very good stress cracking resistance, very high bending fatigue life and very good heat resistance, the heat-resistant PP plastic is the best heat resistance in five general plastics, and the PP product can be used in a high-temperature environment below 100 ℃ for a long time. The product will not deform obviously when the temperature reaches 150 deg.C, and has excellent chemical stability and inertness to most of acid, alkali, salt and oxidant. PP is a crystalline polymer, and the particles do not melt below a certain temperature, unlike PE or PVC which softens with increasing temperature during heating. Once a certain temperature is reached, the PP particles melt rapidly and can be converted completely to the molten state within a few degrees. The melt viscosity of PP is relatively low, so that it is shapedThe melt viscosity is smaller particularly when the melt flow rate is higher, and the melt is suitable for injection molding of large thin-wall products.

Therefore, the temperature of the water drunk in cold days is not higher than 50 ℃.

The existing stainless steel vacuum thermos cup conforms to the national standard GB/T29606-. According to the standard, taking the most common vacuum cup of 0.4-0.6L as an example, the hot water of 90 degrees can still be kept at more than 40 degrees after 12 hours in the cup. According to daily use habits, 500mL of water can be drunk within 4 hours, and the heat preservation performance of the stainless steel vacuum heat preservation cup is excessive. When people go out for a short time, do exercises, go out to play with children, or drink a cup of water within 4 hours indoors, the water in the cup is too hot, which causes inconvenience for use, and few vacuum cups on the market can be attached to the use scene.

In order to cool down the hot water in the stainless steel vacuum thermos cup, the cover needs to be opened for heat dissipation. The heat preservation performance of the vacuum heat preservation cup is excessive, but the common cup does not have the heat preservation capacity, the hot water in the cup is cooled too fast, and finally, only cold water is left after drinking. There is a need for vacuum cups having insulation properties intermediate between those of vacuum cups and conventional cups. The utility model provides a soft shell thermos cup accords with above-mentioned requirement, and thermal insulation performance is moderate, and more lightly durable, and is particularly suitable for going out to carry.
