Aluminum screw packaging tin and manufacturing method thereof

Abstract

The invention discloses an aluminum screw packaging tin, which comprises a tin bottom, a tin body, a tin shoulder, a tin neck and a tin mouth, wherein an external thread is arranged on the outer wall of the tin neck, an annular groove is arranged below the external thread in the outer wall of the tin neck, and a convex ring is formed between the annular groove and the external thread. The invention also discloses a manufacturing method of the aluminum screw packaging tin, which comprises the following steps: roasting an aluminum sheet; stamping; trimming; cleaning; carrying out protective treatment; retracting to form the tin neck; and shaping the tin neck: rolling an external thread on the outer wall of the tin neck close to the screw, and then indenting an annular groove below the external thread in the outer wall of the tin neck to form an annular convex edge between the annular groove and the external thread. The invention has advantages of beautiful integral appearance, good visual effect, thin wall, low manufacturing cost, good forgery prevention effect, high added value, high grade and the like, and can fixedly lock the threaded cover locking mouth ring connected with the tin mouth.

Description

[technical field] [0001] The invention relates to an aluminum screw packaging can and a manufacturing method thereof. [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. , At the same time, the moisture-proof and water-proof labels on the glass packaging jars are poor, which makes the transporta...

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.

At the same time, the label on the glass packaging jar is moisture-proof and has poor water resistance, which makes the transportation and storage cost high

For this reason, people began to use aluminum screw-top packaging cans. The wall thickness of the existing aluminum screw-top packaging cans is generally greater than 2 mm, and the walls of the packaging cans are thicker, so that the product uses more materials and the manufacturing cost is high.

In addition, the existing aluminum screw-top packaging cans are directly provided with threads or sleeves with external threads on the outer wall of the can neck near the mouth of the tank, because the part below the thread on the outer wall of the can neck does not have any decoration. shape, and did not take into account the settings for effectively fixing and locking the screw cap of the tank mouth, so that the whole packaging tank is not beautiful enough, and the anti-counterfeiting effect is poor; for this reason, it is necessary to improve the existing technology
