Description

Technical Field

[0001] The utility model relates to the technical field of spiral thinning cups, in particular to a low metal thermal conductivity spiral thinning cup. Background Art

[0002] Traditional thermoses are usually made of stainless steel, and the insulation effect is achieved by welding the inner and outer liner and vacuuming. However, there are rigid requirements for the thickness of this material. If it is too thin, it is easy to deform during vacuuming. Common stainless steel material thicknesses are 0.4 mm, 0.5 mm and 0.6 mm, etc. In order to solve the above problems, the spin-thinning technology was born. This technology thins the inner liner from 0.4 mm to 0.15 mm after vacuuming the stainless steel water cup, thereby reducing the weight of the water cup.

[0003] For example, a Chinese patent (publication number: CN215457111U) discloses an integrated stainless steel titanium composite liner thermos cup, comprising an inner liner and a stainless steel outer shell, characterized in that: the inner liner comprises a first inner liner made by stretching a titanium metal disc and a second inner liner made by stretching a stainless steel disc, the first inner liner is concentrically and tightly fitted in the second inner liner, and the upper port of the second inner liner is connected to the upper port of the stainless steel outer shell by welding. The integrated stainless steel titanium composite liner thermos cup of this utility model has only one weld at the cup mouth, which eliminates the hidden danger of dirt and grime hidden in the inner liner due to the weld. It is more hygienic and healthy to use, with fewer welding times, high production efficiency, high pass rate, and is conducive to mass production. The overall thin structure of the double-layer inner liner also makes the two layers of the inner liner fit more tightly, and the weight of the cup body is reduced to the weight of a conventional inner liner, saving materials and lowering costs.

[0004] The above-mentioned one-piece stainless steel titanium composite liner thermos cup still has certain shortcomings. The first liner and the second liner are spun on a thinning machine as a whole to form a thinned section on the liner body. This structure is conducive to mass production and reduces the weight of the cup body. The thinned cup is made of metal material to provide good thermal conductivity. However, during the use of the thinned cup, due to the poor protection performance of the metal material, it is easily damaged by the external environment, affecting the thermal insulation of the liner. Therefore, this application proposes a low metal thermal conductivity thinned cup to solve the above problems. Utility Model Content
