Problems solved by technology

In the above-mentioned patents, since the composite liner is welded into pipes and then plugged to form a composite cylinder, the composite cylinder is welded to the corresponding titanium bottom and stainless steel bottom respectively, and the outer stainless steel body of the liner is welded to the stainless steel bottom to form a ring. Weld seam, if there is a false weld in this weld seam, it will cause the thermos cup to fail to form a vacuum layer when vacuuming, resulting in product scrapping and directly affecting the yield of the thermos cup

Embodiment 1

[0033] A kind of manufacturing method of liner, such as Figure 1 to Figure 3 shown, including the following fabrication steps:

[0034] Step 1, the metal sheet is processed to form a cylindrical outer layer liner 101 with an opening at one end and a bottom at the other end;

[0035] Step 2, after molding the inner liner 102, insert the mouth of the outer liner 101 into the outer liner 101 to form the inner liner body 1;

[0036] Step 3, processing the liner body 1 so that the inner wall of the outer liner 101 and the outer wall of the inner liner 102 are closely attached;

[0037] Step 4, shrinking the mouth of the liner body 1 . The outer layer liner 101 is integrally formed by stretching or formed by welding the outer layer cylinder and the outer bottom. After the inner layer liner 102 is put into the mouth of the outer layer liner 101, the outer layer liner 101 and the outer layer liner are processed. The inner layer liner 102 is tightly fitted and discharges the air be...

Embodiment 2

[0043] A kind of manufacturing method of liner, such as figure 1 , figure 2 as well as Figure 4 As shown, the outer liner 101 in step 1 includes an outer cylinder 1011 and an outer bottom 1012 , and the outer bottom 1012 is welded to the lower end of the outer cylinder 1011 . The molding method of the outer inner liner 101 is simplified, and the manufacturing cost of the outer inner liner 101 is reduced.

[0044] In step 1, the stainless steel plate, copper plate or aluminum plate is crimped to form the outer cylinder 1011, the curled butt joint of the outer cylinder 1011 is a longitudinal weld 2, and the longitudinal weld 2 extends longitudinally along the axis of the outer cylinder 1011 . The molding method of the outer cylinder body 1011 is simplified, and the processing efficiency of the outer cylinder body 1011 is improved.

Embodiment 3

[0046] A kind of manufacturing method of liner, such as Figure 5 and Image 6 As shown, the difference from Example 1 is that in step 2, the mouth of the inner liner 102 is necked after the inner liner 102 is formed, and then the mouth of the outer liner 101 is inserted into the outer layer. The liner body 1 is formed in the liner 101 .

[0047] In step 4, the outer liner 101 is necked. Insert the inner liner 102 after the necking process into the outer liner 101 for processing, and then perform shrinking processing on the mouth of the outer liner 101, so that the gap between the mouths of the inner liner 102 and the outer liner 101 is There is a gap between them, which simplifies the processing method of the inner tank body 1 mouth.

Abstract

The invention relates to the technical field of heat preservation containers, and discloses a manufacturing method of an inner container and a container with the inner container, and the manufacturing method comprises the following manufacturing steps: step 1, a stainless steel plate or a copper plate or an aluminum plate is processed to form a cylindrical outer-layer inner container with an opening at one end and a bottom at the other end; 2, the inner-layer inner container is formed and then inserted into the outer-layer inner container from the opening of the outer-layer inner container to form an inner container body; 3, the inner container body is machined, so that the inner wall of the outer-layer inner container is tightly attached to the outer wall of the inner-layer inner container; and 4, necking processing is conducted on the opening portion of the inner container body. The outer-layer inner container is integrally formed or formed by welding the barrel and the bottom, the inner-layer inner container is inserted from the opening of the outer-layer inner container and tightly attached through the rotary thinning or bulging technology, and the sealing performance of the inner container body and the structural stability are improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation containers, in particular to an inner container and a method for manufacturing a container with the inner container. Background technique [0002] At present, the thermos cups on the market are basically stainless steel vacuum thermos cups, and the acid resistance and heavy metal content of 304 stainless steel can no longer meet the daily use scenarios of consumers, such as tea, beverages, acidic drinks or food. The process is prone to acid corrosion or the precipitation of heavy metals, which will affect human health. In recent years, due to the advantages of titanium material itself, the above shortcomings of 304 stainless steel can be solved, making it healthier, but the price of titanium material is high, and existing titanium cups have poor thermal insulation performance and chronic air leakage. In the prior art, the inner tank of the composite titanium cup is made of the inner an...
