Problems solved by technology

[0002] General food cans use tinplate, glass and glue, while glass is relatively stable but bulky, heavy and easy to break, which is not conducive to recycling
However, rubber is not suitable for long-term storage. It will release harmful substances at high temperatures, which will have a certain impact on the stored liquid substances, and it is also not conducive to packaging and recycling, causing pollution to the environment.
The traditional tinplate outer packaging such as: beverages, etc., because of the use of the inner coating, which contains bisphenol A, since 2012, the United States PDA / California 65, Europe and other countries ROSH / DN71, etc. The surface in contact has been set to strict standards and content control, and tinplate is always iron coated, the welding surface and itself are easy to oxidize and rust, which is not conducive to long-term storage

Embodiment Construction

[0023] The best embodiment of the present invention will be further described in detail below.

[0024] like figure 1 As shown, the tank body includes a bottom 1, a tank body 2, a cover 3, a mouth 4, and a knob 5. The cross section of the tank body 2 is a transparent body with a square or circular or other shape, and the lower part of the transparent body is sealed. The bottom 1 is set, and the upper part of the transparent body is sealed with a cover 3. The cover 3 is provided with a mouth 4 near the edge, and a knob 5 is sealed on the mouth 4.

[0025] The bottom 1, the tank body 2 and the tank body 2 and the cover 3 are sealed and connected by folding and pressing.

[0026] The face cover 3 is provided with a hole, and the mouth 4 is an inverted T-shaped structure. After the mouth 4 passes through the hole, the bottom of the mouth 4 is closely attached to the lower side of the face cover 3 and pressed tightly to make it tightly connected.

[0027] The outer wall of the mo...

Abstract

The invention discloses a tank body and a production process. The tank body includes a bottom, a tank body, a cover, a mouth and a knob. The cross section of the tank body is a transparent body such as a square or a circle, and the lower part of the transparent body is sealed. The bottom and the upper part of the transparent body are sealed with a cover, and the cover is provided with a mouth near the edge, and a knob is sealed on the mouth. Its production process includes the following steps: 1. Select rectangular raw materials, and weld the seams after rolling; 2. Expand and shape the product in step 1 through a hydraulic press; 3. According to the cross-sectional shape of the can body in step 2, Select the original material with the same cross-sectional shape as the cover, and press the mouth and the cover with the mouth of the inverted T-shaped structure with a press; 4. According to the cross-sectional shape of the can body in step two, select the raw material with the same cross-sectional shape as the bottom; 5. Use an automatic seaming machine to compress the cover and bottom by folding and compacting. It is small in size, light in weight, not easy to damage, easy to recycle and reuse; no pollution, no harmful substances, and can be stored for a long time.

Description

technical field [0001] The invention belongs to the technical field of machinery manufacturing, and specifically relates to a can body and a production process for packaging all liquids such as cans, wines, beverages, liquid condiments, edible oils, solvents, paints, and the like. Background technique [0002] Generally, tinplate, glass and glue are used for food cans, and glass is relatively stable but bulky, heavy and easy to break, which is not conducive to recycling. However, rubber is not suitable for long-term storage. It will release harmful substances at high temperatures, which will have a certain impact on the preserved liquid substances, and it is also not conducive to packaging and recycling, causing pollution to the environment. The traditional tinplate outer packaging such as: beverages, etc., because of the use of the inner coating, which contains bisphenol A, since 2012, the United States PDA / California 65, Europe and other countries ROSH / DN71, etc. The cont...
