The water sealing part and the necking part are in abutting fit with a sealing ring arranged at the lower end of the cup cover to form water seal.

The stainless steel shell is formed by welding the shell body and the shell bottom, a vacuum layer is arranged between the inner container and the stainless steel shell, and threads used for screwing the cup cover are arranged at the upper port of the stainless steel shell.

Compared with the prior composite liner technology, the utility model has the beneficial effects that:

1. by adopting the technical scheme, the inner container is a first inner container made by stretching a titanium metal wafer and a second inner container made by stretching a stainless steel wafer, the first inner container is concentrically and tightly matched and arranged in the second inner container, the upper end opening part of the second inner container is connected with the upper end opening part of the stainless steel shell in a welding manner, the double-layer composite inner container with the structure is made by stretching, only one welding part is arranged at the cup opening, the welding times are reduced, meanwhile, the generation of welding defective products is greatly reduced, the production efficiency is improved, a seamless inner container can be further obtained, the hidden danger of dirt storage and dirt holding due to the welding seam in the inner container is avoided, and the use is more sanitary and healthy;

2. the first inner container and the second inner container are integrally spun by the spinning machine to form a spinning section on the body part of the inner container, and the structure is beneficial to mass production, reduces the weight of the cup body, saves materials and has lower cost;

3. the first inner container and the second inner container are integrally formed through necking by the air compressor, so that a water sealing part, a necking part and a shoulder part are formed at the upper end opening part of the inner container from top to bottom, and the structure not only meets the water sealing function, but also can enable the first inner container and the second inner container to be matched more tightly, and avoids the first inner container and the second inner container from being loosened;

4. the whole cup body is welded only between the stainless steel of the cup mouth and the stainless steel, the technology is mature, and the production efficiency and the qualified rate are high.
