Problems solved by technology

Problems in the above-mentioned invention patents: because the titanium steel double-layer liner is not fully bonded, there will be water between the titanium layer and the steel layer in the manufacturing process due to water rising, cleaning and vacuuming. Penetration requires subsequent drying for a long time to dry the infiltration water, which increases production costs
Although the above-mentioned patent is also a titanium-steel double-layer composite cup, the titanium layer of the inner tank and the steel layer of the inner tank are plugged in. In fact, there is a gap and separation between the two layers. The titanium inner tank can be taken out. Titanium cups have poor thermal insulation performance

Embodiment 1

[0035] a liner, such as Figure 1 to Figure 3 As shown, it includes an inner container body 1, which is composed of an outer layer inner container 2 and an inner layer inner container 3, and also includes a seam welding ring 8 arranged between the outer layer inner container 2 and the inner layer inner container 3. Roll welding rings 8 are evenly distributed from the bottom of the inner container to the mouth of the inner container. The connection strength between the outer liner 2 and the inner liner 3 is enhanced, and water or impurities are prevented from entering the outer liner 2 and the inner liner 3, which affects the use of the inner liner 1.

[0036] The inner liner 3 is made of titanium material, and the outer liner 2 is made of metal material other than titanium material. The outer liner 2 is made of stainless steel, copper or aluminum. The thickness of liner 1 is 0.05-0.5 mm, and the thickness of inner liner 3 is 0.03-0.2 mm. When the inner tank body 1 is filled...

Embodiment 2

[0040] A kind of manufacturing method of liner, such as figure 1 , figure 2 , Figure 4 , Figure 5 Shown, be used to manufacture a kind of liner described in embodiment 1, comprise the following steps:

[0041] Step 1, taking the inner liner blank formed by compounding the outer liner 2 and the inner liner 3;

[0042] Step 2, process the liner blank by the seam welding process, so that a seam welding ring 8 is formed between the outer liner 2 and the inner liner 3

[0043] Step 3, performing hot or cold spinning processing on the side wall of the liner blank to form the liner body 1 including the outer liner 2 and the outer liner 2 . The liner body 1 is the liner of the thermos cup or the liner of the pot.

[0044] The seam welding process in step 2 includes:

[0045] 1), inserting the copper mandrel 4 connected to the negative pole of the power supply inside the inner liner 3 and driving the inner liner blank to rotate;

[0046] 2), the seam welding wheel 5 connected...

Embodiment 3

[0054] A kind of manufacturing method of liner, such as Figure 1 to Figure 3 as well as Figure 5 As shown, the difference from Example 1 is that when the inner container body 1 is a thermos cup inner container, step 4 is also included, and the mouth of the inner container body 1 is screwed and compressed to form a cup mouth 9 . The liner body 1 is formed into a thermos cup liner. When the thermos cup is filled with a solution, the inner liner 3 made of titanium material is in contact with the solution to improve the hygiene and health of the thermos cup when it is filled with a solution.

[0055] The invention also discloses a manufacturing method of a container. After the inner container is manufactured as above, step 5 is also included. The connection is fixed and sealed, and a vacuum is drawn between the inner tank body 1 and the outer shell 12.

Abstract

The invention relates to the field of inner containers, and discloses an inner container, a container and a manufacturing method. The inner container comprises an inner container body composed of an outer-layer inner container and an inner-layer inner container, and the inner container further comprises a roll welding ring arranged between the outer-layer inner container and the inner-layer inner container. The method further comprises the following steps that 1, an inner container blank formed by an outer-layer inner container and an inner-layer inner container is taken; 2, the inner container blank is machined through a roll welding process, so that a roll welding ring is formed between the outer-layer inner container and the inner-layer inner container; and 3, hot or cold spinning machining is conducted on the side wall of the inner container blank to form an inner container body comprising the outer-layer inner container and the outer-layer inner container. After the ring roll welding process is adopted for the wall part of the inner container blank, the connection strength between the outer-layer inner container and the inner-layer inner container is enhanced.

Description

technical field [0001] The invention relates to the field of inner pots, in particular to an inner pot, a container and a manufacturing method. Background technique [0002] At present, the titanium metal liner on the market is often complex in structure and of low use value. In order to look good and not rust, it is made of titanium alloy or stainless steel. Titanium alloy is expensive, and stainless steel contains heavy metals, which is not good for human health. For example, the invention patent application 202010068652.4 discloses a thermos cup with a titanium composite liner and its manufacturing process, including the liner body, the liner body includes a first liner layer and a second liner layer, the first liner layer and The second inner liner layer is concentrically arranged, the first inner liner layer is made of stainless steel or copper material or iron material or aluminum material, the second inner liner layer is made of titanium material, and the lower end of...
