Double-waist aluminum packaging tin and production method

Abstract

The invention discloses a double-waist aluminum packaging tin, which comprises a tin bottom, wherein the edge of the tin bottom extends upward to form a lower tin body; the upper of the lower tin body shrinks upward to form a first level tin waist; the upper of the first level tin waist shrinks upward to form a second level tin waist; the upper of the second level tin waist shrinks upward again to form an upper tin body; the upper of the upper tin body shrinks upward to form a tin shoulder; and the upper part of the tin shoulder is flanged to form a tin port with a lip. The invention also discloses a production method for the double-waist aluminum packaging tin. The method comprises the following steps: frying slices, punching; finishing; cleaning; protection treatment; and necking which is as follows: open of the crude tin blank is shrunk to form the first level tin waist, the lower tin body is partly formed between the first tin waist and the tin bottom, the upper part of the first level tin waist is shrunk upwardly to form the second level tin waist, the upper part of the second level tin waist is shrunk upwardly again to form the upper tin body, the upper part of the upper tin body is shrunk upwardly to form the tin shoulder, and the upper part of the tin shoulder is flanged to the tin port with lips. The invention has the advantages of easy and firm holding, overall attractive appearance, strong vision and touch stereoscopic impression, high added value, high grade and the like.

Description

[technical field] [0001] The invention relates to an aluminum packaging can and a manufacturing method. [Background technique] [0002] A packaging can is a packaging container widely used in various industries, and can be used to hold beverages, liquors, etc. The packaging tank is easy to operate, safe and reliable, and is deeply loved by users. [0003] At present, the packaging jars used in the market are generally made of glass, and the glass packaging jars have the following disadvantages: poor light-shielding performance, unable to adapt to the filling in them; The body is not easy to print, and is usually marked with a label, which has poor anti-counterfeiting properties. At the same time, the label on the glass packaging jar has poor moisture-proof and water-proof performance, which makes transportation and storage costs high. For this reason, people began to use aluminum packaging cans, but because the outer wall surface of cylindrical cans is relatively smooth, w...

Problems solved by technology

[0003] At present, the packaging jars used in the market are generally made of glass, and the glass packaging jars have the following disadvantages: poor light-shielding performance, unable to adapt to the filling in them; The body is not easy to print, and is usually marked with a label, which has poor anti-counterfeiting. At the same time, the label on the glass packaging jar has poor moisture-proof and water-proof performance, which makes the transportation and storage costs high.

For this reason, people began to use aluminum packaging cans, but because the outer wall surface of cylindrical cans is relatively smooth, when people are not careful or their grip is loose, the packaging cans are easy to slip from their hands, and the overall appearance is not beautiful enough, and the visual effect is relatively poor. It is necessary to improve the existing technology
