Description
Technical Field
The invention relates to the technical field of containers, in particular to a container and a manufacturing method thereof.
Background
The thermos cup and the kettle are common containers for drinking water or containing real objects. The inner container and the outer shell of the metal vacuum cup on the market are usually made of stainless steel, and the stainless steel of the inner container can not contain drinks with acidity, milk and the like. At present, a plurality of manufacturers begin to use the titanium material as the inner container of the vacuum cup, but the titanium metal is expensive and is difficult to weld with the stainless steel shell, so that the titanium vacuum cup is high in price, and the popularization of the titanium vacuum cup is influenced. And a vacuum cup using enamel or ceramic as an inner container, wherein the enamel or ceramic has high hardness, high temperature resistance, wear resistance and other excellent performances. For example, the Chinese invention patent (application number: CN201220218821.9) discloses a titanium double-layer vacuum cup, which comprises a cup body and a cup cover, wherein the cup body comprises a titanium metal inner container and a titanium metal outer shell, a gap layer is arranged between the titanium metal inner container and the titanium metal outer shell, the inner container and the outer shell of the cup body are both made of titanium metal with the titanium content of 95 percent or more, and the gap layer is internally vacuum or air. In the patent, because titanium metal is soft, a single-layer titanium metal is used as the inner container, and the thickness of the inner container cannot be too thin, the inner container and the shell of the vacuum cup are both made of titanium alloy, so that the price is too high, and the vacuum cup cannot be popularized in the public. For another example, the chinese patent application No. CN202010068652.4 discloses a vacuum cup with a titanium composite inner container, which comprises an inner container body and a shell. The inner container body is formed by a first inner container layer and a second inner container layer in one step through a spinning process, and the first inner container layer and the second inner container layer are arranged concentrically. The first inner container layer is made of stainless steel material or copper material or iron material or aluminum material, and the second inner container layer is made of titanium material. The lower extreme of inner bag body is equipped with first bottom and second bottom. The first bottom layer and the second bottom layer are formed in one step through a stretching process, the first bottom layer is fixedly connected with the lower end part of the first inner container layer through laser welding or brazing, and the second bottom layer is fixedly connected with the lower end part of the second inner container layer through laser welding or brazing. The shell is arranged on the outer side of the first inner container layer and is connected with the outer side wall of the first inner container layer. Although the liner of the vacuum cup in the patent is made of double-layer composite materials, the liner of the vacuum cup is scrapped due to the bad phenomenon of layering generated in the vacuum pumping process and is difficult to weld with a stainless steel shell, and because different metals have different melting points, the stainless steel bars are roll-welded outside titanium, so that the welding problem is solved, but the roll welding cannot ensure vacuum sealing.
